From 15b2355343d542e991a517f56443cd276e412b92 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 4 Mar 2026 08:21:44 +0000 Subject: [PATCH 001/114] Expand 003 dynamic IR construction with five detailed proposals MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Analyze the full query pipeline (DSL → RawSelectInput → Desugar → Canonicalize → Lower → IRSelectQuery) and propose five approaches for dynamic query building: raw IR helpers (A), fluent builder (B), dynamic DSL with string resolution (C), extending SelectQueryFactory (D), and composable path objects (E). Includes comparison matrix, code examples, and a phased implementation plan.

But a CMS (or any data-driven UI) needs to build queries **at runtime**: the user picks which shape to query, which properties to include, possibly chains like `person.friends.name`, all from configuration or UI state. Today the only way to do this is to construct raw IR objects by hand — verbose, error-prone, and requires deep knowledge of the IR types. -1. **Variable shapes**: Build queries where the target shape is determined at runtime, not compile time. -2. **Variable property paths**: Construct traversal paths dynamically (e.g. from a configuration or user input). -3. **Shared path endpoints (variables in DSL)**: When the result of one path needs to be referenced in another path — e.g. "find persons whose best friend's hobby matches any of their own friends' hobbies". This requires introducing variable-like references into the DSL. -4. **Programmatic IR building**: Utility functions to construct `SelectQuery`, `CreateQuery`, etc. directly without going through the Shape DSL pipeline. Useful for generated queries, migration scripts, admin tools. -5. **IR composition**: Combining partial IR fragments into larger queries. +We need a **public, dynamic query-building API** that sits between the static DSL and the raw IR. -## Relationship to SPARQL conversion (001) +--- + +## Architecture Recap + +The current pipeline looks like: + +``` +Shape DSL (proxy tracing) + ↓ produces RawSelectInput (select/where/sortBy paths) +IRDesugar + ↓ DesugaredSelectQuery +IRCanonicalize + ↓ CanonicalDesugaredSelectQuery +IRLower + ↓ IRSelectQuery (final IR) +buildSelectQuery() ← IRPipeline.ts orchestrates the above + ↓ +irToAlgebra → algebraToString → SPARQL +``` + +The `SelectQueryFactory` wraps the proxy-tracing DSL and calls `buildSelectQuery(rawInput)`. But `buildSelectQuery` also accepts a pre-built `IRSelectQuery` directly (pass-through). That's two possible injection points. + +--- + +## Proposals + +### Option A: Low-level IR Builder (direct IR construction) + +Expose helper functions that produce `IRSelectQuery` objects directly. No proxy tracing, no desugar/canonicalize/lower — you build the final IR yourself with helpers that reduce boilerplate. + +```ts +import { ir } from 'lincd/queries'; + +const query = ir.select({ + root: ir.shapeScan(PersonShape), // → IRShapeScanPattern + patterns: [ + ir.traverse('a0', 'a1', namePropertyShape), // → IRTraversePattern + ir.traverse('a0', 'a2', friendsPropertyShape), + ir.traverse('a2', 'a3', namePropertyShape), + ], + projection: [ + ir.project('name', ir.prop('a1', namePropertyShape)), + ir.project('friendName', ir.prop('a3', namePropertyShape)), + ], + limit: 10, +}); + +// query is a valid IRSelectQuery — pass to store directly +const results = await store.selectQuery(query); +``` + +**Pros:** Full control. No magic. Easily serializable. Works for any query the IR supports (including future MINUS, CONSTRUCT, etc.). + +**Cons:** Verbose. Alias management is manual. Feels like writing assembly. No type inference on results. + +**Best for:** Migration scripts, code generators, admin tooling, advanced one-offs. + +--- + +### Option B: Mid-level Query Builder (fluent chain API) + +A builder that knows about shapes and property shapes, auto-manages aliases, and produces IR via the existing pipeline. This is the "one layer up" from raw IR — it uses `NodeShape` / `PropertyShape` objects but doesn't require a Shape class or proxy tracing. + +```ts +import { QueryBuilder } from 'lincd/queries'; + +const results = await QueryBuilder + .from(PersonShape) // root shape scan + .select(p => [ // p is a dynamic path builder + p.prop(namePropertyShape), // select name + p.prop(friendsPropertyShape) // traverse to friends + .prop(namePropertyShape), // then select their name + ]) + .where(p => + p.prop(agePropertyShape).gte(18) + ) + .limit(10) + .exec(); +``` + +Under the hood, `.from(PersonShape)` creates a root context. `.prop(propertyShape)` appends a step. The builder produces a `RawSelectInput`-equivalent and feeds it through `buildSelectQuery()`. + +**Pros:** Familiar fluent pattern. Shape-aware (validates property belongs to shape). Auto-alias management. Can leverage existing pipeline passes. Mid-complexity. + +**Cons:** New API surface. Need to design the chain types carefully. Result types would be `ResultRow[]` (no static type inference unless we layer generics). + +**Best for:** CMS-style dynamic queries where you know the shapes at runtime. + +--- + +### Option C: "Dynamic DSL" — runtime shape + property path resolution + +Keep the existing DSL patterns but accept string-based or reference-based shape/property lookups. The API looks almost identical to the static DSL but everything is resolved at runtime. + +```ts +import { DynamicQuery } from 'lincd/queries'; + +// By shape + property shape references (most reliable) +const results = await DynamicQuery + .shape(PersonShape) + .select([ + namePropertyShape, // simple property + [friendsPropertyShape, namePropertyShape], // chained path: friends.name + { hobby: [hobbiesPropertyShape, labelPropertyShape] }, // aliased path + ]) + .where(agePropertyShape, '>=', 18) + .limit(10) + .exec(); + +// Or by string labels (convenient, resolves via shape metadata) +const results = await DynamicQuery + .shape('Person') + .select(['name', 'friends.name', { hobby: 'hobbies.label' }]) + .where('age', '>=', 18) + .exec(); +``` + +Internally this would: +1. Resolve shape name → `NodeShape` +2. Parse property paths (string or reference arrays) → walk `NodeShape.properties` to find each `PropertyShape` +3. Build a `RawSelectInput` from the resolved paths +4. Feed into `buildSelectQuery()` + +**Pros:** Extremely CMS-friendly. Accepts strings (for config files, URL params, user input). Path chains are intuitive (`'friends.name'`). Minimal API surface. + +**Cons:** String resolution adds a lookup cost and error surface. No compile-time type safety (result is `ResultRow[]`). Need to handle ambiguous/missing property names. + +**Best for:** Config-driven CMS queries, REST/GraphQL endpoint generation, admin UIs. + +--- + +### Option D: Hybrid — Extend `SelectQueryFactory` to accept dynamic inputs + +Instead of a new API, extend the existing `SelectQueryFactory` to accept property shapes directly, bypassing proxy tracing. The factory already has all the machinery (`toRawInput()`, `build()`, `exec()`). + +```ts +import { Shape } from 'lincd'; + +// New static method on Shape — mirrors .select() but with explicit property shapes +const results = await Shape.dynamicSelect(PersonShape, { + select: [ + namePropertyShape, + [friendsPropertyShape, namePropertyShape], + ], + where: { + property: agePropertyShape, + operator: '>=', + value: 18, + }, + limit: 10, +}); + +// Or: use the existing factory with a new input mode +const factory = new SelectQueryFactory(PersonShape); +factory.addSelection(namePropertyShape); +factory.addSelection([friendsPropertyShape, namePropertyShape]); +factory.setWhereClause(agePropertyShape, '>=', 18); +factory.setLimit(10); +const results = await factory.exec(); +``` + +**Pros:** Reuses existing `SelectQueryFactory` infrastructure. Minimal new code. Familiar patterns. + +**Cons:** `SelectQueryFactory` is already complex (1800+ lines). Adding more modes increases complexity. May conflict with proxy-based initialization. + +**Best for:** Incremental adoption. Keeps everything in one place. + +--- + +### Option E: Composable Path Objects (standalone, composable, reusable) + +Define a `PropertyPath` value object that can be composed, stored, and reused. Queries are built by combining paths. + +```ts +import { path, select } from 'lincd/queries'; + +// Define reusable paths +const name = path(PersonShape, namePropertyShape); +const friendsName = path(PersonShape, friendsPropertyShape, namePropertyShape); +const age = path(PersonShape, agePropertyShape); + +// Compose into a query +const query = select(PersonShape) + .fields(name, friendsName) + .where(age.gte(18)) + .limit(10); + +const results = await query.exec(); + +// Paths are reusable across queries +const otherQuery = select(PersonShape) + .fields(name) + .where(friendsName.equals('Alice')); +``` + +**Pros:** Maximally composable. Paths are first-class values — store them, pass them around, derive from them. Good for CMS schemas where paths are defined in config. + +**Cons:** New concept (path objects). Need to design path composition carefully (what happens when you extend a path from one shape into another?). + +**Best for:** Schema-driven systems where field selections are defined as data. + +--- + +## Comparison Matrix + +| Concern | A (Raw IR) | B (Fluent Builder) | C (Dynamic DSL) | D (Extend Factory) | E (Path Objects) | +|---|---|---|---|---|---| +| Verbosity | High | Medium | Low | Medium | Low | +| Type safety | None | Partial | None | Partial | Partial | +| Learning curve | Steep | Medium | Low | Low | Medium | +| CMS friendliness | Low | High | Highest | Medium | High | +| String-based input | No | No | Yes | No | No | +| Composability | Manual | Chain only | Limited | Chain only | Excellent | +| New API surface | Small (helpers) | Medium (new class) | Medium (new class) | Small (extends existing) | Medium (new types) | +| Reuses pipeline | No (bypass) | Yes | Yes | Yes | Yes | +| Mutation support | Separate | Could extend | Could extend | Could extend | Separate | + +--- + +## Recommendation for CMS + +For a CMS, **Option C (Dynamic DSL)** is the fastest path to productivity: +- You already have `NodeShape` / `PropertyShape` metadata at runtime +- String paths like `'friends.name'` map naturally to CMS field configs +- The implementation can resolve strings via existing `getPropertyShapeByLabel()` +- Feeds directly into the existing pipeline — minimal new code + +**Option B (Fluent Builder)** is the best long-term investment: +- Clean separation of concerns +- Works well as the backbone that Option C delegates to +- Can be extended for mutations (create/update builders) + +**Suggested approach: B + C layered.** Build the fluent builder (B) first as the core engine.

The trick is that `RawSelectInput.select` expects `SelectPath` — which is `QueryPath[] | CustomQueryObject`. A `QueryPath` is an array of `QueryStep` objects, where each step has a `.property` (PropertyShape). + +This means `QueryBuilder.toRawInput()` can produce the same structure directly: + +```ts +// Inside QueryBuilder +private toRawInput(): RawSelectInput { + const select: QueryPath[] = this._selections.map(sel => { + const steps = this.selectionToSteps(sel); + return steps.map(prop => ({ property: prop })); // QueryStep + }); + + return { + select, + shape: this._shape, + limit: this._limit, + offset: this._offset, + singleResult: false, + where: this._where.length ? this.buildWherePath() : undefined, + }; +} +``` + +This is the key insight: **we don't need to create new pipeline stages.** We produce the same `RawSelectInput` that proxy tracing produces, but we build it from explicit property shape references instead of proxy interception. + +--- + +## Open Questions + +1. **Result typing:** Dynamic queries can't infer result types statically. Should we provide a generic `ResultRow` type, or allow users to pass a type parameter (`QueryBuilder.from(PersonShape)`)? + +2. **Mutation builders:** Should `QueryBuilder` also support `.create()`, `.update()`, `.delete()` methods? The mutation IR (`IRCreateMutation`, etc.) is simpler — it might be easier to just expose the existing `buildCanonicalCreateMutationIR()` etc. directly. + +3. **Validation:** Should the builder validate that property shapes actually belong to the root shape (or its traversed shapes)? This catches errors early but adds overhead. + +4. **Where clause composition:** The static DSL uses proxy chaining for where clauses (`p.name.equals('John').and(p.age.gte(18))`). The builder needs a different pattern. Options: + - Condition objects: `where(age.gte(18))` — simple and explicit + - Nested callback: `where(p => p.prop(age).gte(18).and(p.prop(name).equals('John')))` — closer to DSL feel + - Plain objects: `where({ property: age, operator: '>=', value: 18 })` — most serializable (good for CMS configs stored as JSON) + +5. **Path reuse across queries:** If paths are first-class (Option E influence), they could be defined once in a CMS schema config and reused across list views, detail views, filters, etc. + +--- + +## Implementation Plan + +### Phase 1: Core builder (Option B) +- [ ] `PropertyPath` value object +- [ ] `PathBuilder` with `.prop()` and comparison methods +- [ ] `QueryBuilder` with `.from()`, `.select()`, `.where()`, `.limit()`, `.offset()`, `.build()`, `.exec()` +- [ ] Internal `toRawInput()` bridge to existing pipeline +- [ ] Tests: verify builder-produced IR matches DSL-produced IR for equivalent queries -These dynamic IR features produce the same IR types (`SelectQuery`, etc.) that the SPARQL conversion layer consumes.

This leads to: + +1. **Duplication** — The PersonCard needs `name + avatar + address.city`. The PersonDetail also needs those, plus more. If you change the card's fields, you have to remember to update the detail page too. + +2. **No query merging** — In the drag-drop builder, a user drops a PersonCard and a HobbyList onto a page. Each component has its own query. Ideally the system merges them into one SPARQL query that fetches everything needed for both. Without a composable selection type, merging is ad-hoc. + +3. **No incremental building** — The NL chat wants to start with "show people" (basic fields), then the user says "also show their hobbies" — you need to extend the selection, not rebuild it from scratch. + +### Solution: `FieldSet` — a composable, reusable selection set + +A `FieldSet` is a named collection of property paths rooted at a shape. It's the E-style path object idea, but designed as a *set of paths* rather than individual paths, because in practice you almost always want a group. + +```ts +import { FieldSet } from 'lincd/queries'; + +// ── Define reusable field sets ────────────────────────────────── + +// A concise summary of a person — used in cards, table rows, autocompletes +const personSummary = FieldSet.for(PersonShape, [ + 'name', + 'email', + 'avatar', +]); + +// Full address — used in forms, detail pages, map components +const fullAddress = FieldSet.for(AddressShape, [ + 'street', + 'city', + 'postalCode', + 'country', +]); + +// Person's address, using a nested FieldSet +const personAddress = FieldSet.for(PersonShape, { + address: fullAddress, // nest: person.address.{street, city, ...} +}); + +// Person card = summary + address city only +const personCard = FieldSet.for(PersonShape, [ + personSummary, // include another FieldSet + 'address.city', // plus one extra path +]); + +// Person detail = card + more +const personDetail = FieldSet.for(PersonShape, [ + personCard, // everything the card needs + 'bio', + 'age', + { friends: personSummary }, // friends, using the same summary view + 'hobbies.label', +]); +``` + +### CMS surface examples + +#### 1.

Drag-and-drop builder — merging component requirements + +Each component declares its data requirements as a `FieldSet`. When the user drops components onto a page, the builder merges them. + +```ts +// Component declarations (could be decorators, static props, or metadata) +const personCardFields = FieldSet.for(PersonShape, ['name', 'avatar', 'address.city']); +const hobbyListFields = FieldSet.for(PersonShape, ['hobbies.label', 'hobbies.description']); +const friendGraphFields = FieldSet.for(PersonShape, [ + 'name', + { friends: FieldSet.for(PersonShape, ['name', 'avatar']) }, +]); + +// User drops PersonCard + HobbyList onto a page +// Builder merges their field sets into one query +const merged = FieldSet.merge([personCardFields, hobbyListFields]); +// merged = ['name', 'avatar', 'address.city', 'hobbies.label', 'hobbies.description'] + +const results = await QueryBuilder + .from(PersonShape) + .include(merged) + .exec(); + +// Each component receives the full result and picks what it needs — +// no over-fetching because we only selected the union of what's needed +``` + +#### 4.

These imply chained resolution: first resolve `address` on the `from` shape, then `city` on `address`'s valueShape. The target side similarly resolves `'address.addressLocality'` step by step. This makes dotted path mapping work, but should the adapter also support structural differences where one shape has a flat property and the other has a nested path?

A FieldSet can **export** a binding — declaring "I traverse to this endpoint and name it, so other FieldSets or where clauses can reference it." +A FieldSet can **export** a binding (label an endpoint with `.as()`) or **consume** a binding (constrain a path with `.joins()`). When FieldSets are merged into one query, exports and consumers connect automatically. ```ts -// ── FieldSet with an exported binding ─────────────────────────── - -// "Best friend's hobby" — traverses deep and names the endpoint +// FieldSet A: traverses to bestFriend's hobby and labels the endpoint 'hobby' const bestFriendHobby = FieldSet.for(PersonShape, (p) => [ - p.path('bestFriend.favoriteHobby').as('sharedHobby'), + p.path('bestFriend.favoriteHobby').as('hobby'), ]); +// This FieldSet says: "I select bestFriend.favoriteHobby and I call that endpoint 'hobby'" -// "Hobbies that match" — joins on the named binding +// FieldSet B: traverses to hobbies and constrains to the 'hobby' endpoint const matchingHobbies = FieldSet.for(PersonShape, (p) => [ - p.path('hobbies').joins('sharedHobby'), + p.path('hobbies').joins('hobby'), ]); +// This FieldSet says: "I select hobbies, but only those that are the same node as 'hobby'" -// Compose them — the binding connects the two FieldSets +// When included together, the binding connects them: const query = QueryBuilder .from(PersonShape) - .include(bestFriendHobby) - .include(matchingHobbies) + .include(bestFriendHobby) // exports 'hobby' binding + .include(matchingHobbies) // consumes 'hobby' binding .exec(); -// → the merge sees that 'sharedHobby' is exported by bestFriendHobby -// and consumed by matchingHobbies — they share a ?variable ``` -This works because: -1. `FieldSet.merge()` collects all binding declarations across included FieldSets -2.

Risk: name collisions when merging independently authored FieldSets. + - **Per-FieldSet with export**: each FieldSet has its own namespace. `.as()` is local; an explicit `.export('name')` publishes it to the query scope. More safe but more verbose. + - **Hierarchical**: FieldSets inherit parent scope. A sub-FieldSet (nested under a traversal) can see parent bindings but not vice versa. + - **Recommendation**: Start with per-query (simple), add namespacing later if collision becomes a real problem. + +2. **Binding validation**: When should we error on an unresolved `.joins()` reference? + - **Eagerly** (at FieldSet creation): impossible — the exporting FieldSet might not be included yet. + - **At query build time** (when `toRawInput()` or `build()` is called): best option. All FieldSets have been included, so we can check that every `.joins('x')` has a matching `.as('x')`. + - **At SPARQL generation**: too late, confusing error messages. + - **Recommendation**: Validate at `build()` time. Clear error: "Binding 'hobby' is referenced by `.joins('hobby')` but no path declares `.as('hobby')`. Did you forget to include a FieldSet?" + +3. **Multiple exporters**: What if two FieldSets both declare `.as('hobby')`? + - **Error**: strictest, prevents confusion. + - **Last-wins**: simple but fragile. + - **Merge if compatible**: if both paths end at the same shape/type, allow it (they agree on the semantic). If they disagree, error. + - **Recommendation**: Error by default. Users should use one FieldSet for one binding name. + +4. **Cross-shape bindings**: The examples above show bindings connecting two different shapes (UserShape + ProductShape). This requires multi-shape queries — a separate feature. Should bindings be designed now to handle this, or scoped to single-shape queries first? + - **Recommendation**: Design the binding types to be shape-agnostic (just string labels + path references). Multi-shape query support can land later; bindings "just work" with it because they're resolved at the IR level where shapes are already flattened to aliases. + +5. **Binding + OPTIONAL**: If a path with `.joins()` is inside an OPTIONAL block, the semantics change — the join only applies when the OPTIONAL matches.

When the adapter uses `{id: someIRI}` references, those are used directly. But what about dotted paths like `'address.city'`? These imply chained resolution: first resolve `address` on the `from` shape, then `city` on `address`'s valueShape. The target side similarly resolves `'address.addressLocality'` step by step. This makes dotted path mapping work, but should the adapter also support structural differences where one shape has a flat property and the other has a nested path? (e.g. `'city'` → `'address.addressLocality'`). Probably yes, but that's a later extension.

Same name = same variable, period. -The key: both `ex:favoriteHobby ?hobby` and `ex:hobbies ?hobby` use the same `?hobby`. Only people whose hobbies list includes their best friend's favorite are returned. +**What v1 must do to prepare:** -#### How bindings compose with FieldSets - -A FieldSet can **export** a binding (label an endpoint with `.as()`) or **consume** a binding (constrain a path with `.joins()`). When FieldSets are merged into one query, exports and consumers connect automatically. - -```ts -// FieldSet A: traverses to bestFriend's hobby and labels the endpoint 'hobby' -const bestFriendHobby = FieldSet.for(PersonShape, (p) => [ - p.path('bestFriend.favoriteHobby').as('hobby'), -]); -// This FieldSet says: "I select bestFriend.favoriteHobby and I call that endpoint 'hobby'" - -// FieldSet B: traverses to hobbies and constrains to the 'hobby' endpoint -const matchingHobbies = FieldSet.for(PersonShape, (p) => [ - p.path('hobbies').joins('hobby'), -]); -// This FieldSet says: "I select hobbies, but only those that are the same node as 'hobby'" - -// When included together, the binding connects them: -const query = QueryBuilder - .from(PersonShape) - .include(bestFriendHobby) // exports 'hobby' binding - .include(matchingHobbies) // consumes 'hobby' binding - .exec(); -``` - -Generated SPARQL: -```sparql -SELECT ?person ?hobby WHERE { - ?person a ex:Person . - ?person ex:bestFriend/ex:favoriteHobby ?hobby . ← exported as 'hobby' - ?person ex:hobbies ?hobby . ← joined to 'hobby' -} -``` - -The merge collects binding declarations across all FieldSets. A `.joins('hobby')` in one FieldSet matches `.as('hobby')` from another. At the IR level, both paths get the same alias → same SPARQL variable. - -#### More realistic CMS examples - -```ts -// ── "Products in the same category as the user's wishlist" ────── -// -// Two shapes involved: UserShape and ProductShape -// The binding connects them: user's wishlist category = product's category - -const wishlistCategory = FieldSet.for(UserShape, (p) => [ - p.path('wishlist.category').as('cat'), // label: the category node -]); -// Traverses: user → wishlist → category → ?cat - -const productsInCategory = FieldSet.for(ProductShape, (p) => [ - p.path('category').joins('cat'), // must be the same category node - p.path('name'), - p.path('price'), -]); -// Traverses: product → category → ?cat (same node!) - -// Generated SPARQL: -// SELECT ?cat ?productName ?productPrice WHERE { -// ?user ex:wishlist/ex:category ?cat . ← path A ends at ?cat -// ?product ex:category ?cat . ← path B ends at ?cat (same node) -// ?product ex:name ?productName . -// ?product ex:price ?productPrice . -// } -// Note: multi-shape queries are a separate feature, but bindings compose with it. - - -// ── "Articles written by friends of the current user" ─────────── -// -// Binding: the friend node = the article's author - -const userFriends = FieldSet.for(UserShape, (p) => [ - p.path('friends').as('friend'), // label: the friend node -]); -// Traverses: user → friends → ?friend - -const articlesByFriends = FieldSet.for(ArticleShape, (p) => [ - p.path('author').joins('friend'), // author must be the friend node - p.path('title'), - p.path('publishedAt'), -]); -// Traverses: article → author → ?friend (same node as user's friend!) - -// Generated SPARQL: -// SELECT ?friend ?title ?publishedAt WHERE { -// ?user ex:friends ?friend . ← path A ends at ?friend -// ?article ex:author ?friend . ← path B ends at ?friend -// ?article ex:title ?title . -// ?article ex:publishedAt ?publishedAt . -// } - - -// ── NL chat: incrementally adding a binding ───────────────────── -// Step 1: "Show me people and their hobbies" -let chatQuery = QueryBuilder.from(PersonShape) - .select(['name', 'hobbies.label']); - -// Step 2: "Now show which of their friends share the same hobbies" -// The LLM generates code that: -// 1.

Risk: name collisions when merging independently authored FieldSets. - - **Per-FieldSet with export**: each FieldSet has its own namespace. `.as()` is local; an explicit `.export('name')` publishes it to the query scope. More safe but more verbose. - - **Hierarchical**: FieldSets inherit parent scope. A sub-FieldSet (nested under a traversal) can see parent bindings but not vice versa. - - **Recommendation**: Start with per-query (simple), add namespacing later if collision becomes a real problem. - -2. **Binding validation**: When should we error on an unresolved `.joins()` reference? - - **Eagerly** (at FieldSet creation): impossible — the exporting FieldSet might not be included yet. - - **At query build time** (when `toRawInput()` or `build()` is called): best option. All FieldSets have been included, so we can check that every `.joins('x')` has a matching `.as('x')`. - - **At SPARQL generation**: too late, confusing error messages. - - **Recommendation**: Validate at `build()` time. Clear error: "Binding 'hobby' is referenced by `.joins('hobby')` but no path declares `.as('hobby')`. Did you forget to include a FieldSet?" - -3. **Multiple exporters**: What if two FieldSets both declare `.as('hobby')`? - - **Error**: strictest, prevents confusion. - - **Last-wins**: simple but fragile. - - **Merge if compatible**: if both paths end at the same shape/type, allow it (they agree on the semantic). If they disagree, error. - - **Recommendation**: Error by default. Users should use one FieldSet for one binding name. - -4. **Cross-shape bindings**: The examples above show bindings connecting two different shapes (UserShape + ProductShape). This requires multi-shape queries — a separate feature. Should bindings be designed now to handle this, or scoped to single-shape queries first? - - **Recommendation**: Design the binding types to be shape-agnostic (just string labels + path references). Multi-shape query support can land later; bindings "just work" with it because they're resolved at the IR level where shapes are already flattened to aliases. - -5. **Binding + OPTIONAL**: If a path with `.joins()` is inside an OPTIONAL block, the semantics change — the join only applies when the OPTIONAL matches. Is that intended? Should we warn? - -6. **Serialization**: How do bindings serialize in `FieldSet.toJSON()`? - ```json - { - "shape": "PersonShape", - "fields": [ - { "path": "bestFriend.favoriteHobby", "as": "hobby" }, - { "path": "hobbies", "joins": "hobby" } - ] - } - ``` - Simple and JSON-friendly — good for CMS builders that store field configs. - -7. **Naming convention**: `.joins()` might be confused with SQL joins. Alternatives: - - `.sameAs('hobby')` — clear but overloaded (owl:sameAs in RDF) - - `.sharesWith('hobby')` — descriptive but verbose - - `.bindsTo('hobby')` — neutral - - `.constrainTo('hobby')` — explicit about what it does - - `.joins('hobby')` — short and technically accurate for graph joins - - **Open**: which reads best to CMS developers who may not know SPARQL? - -#### What this means for v1 design - -The v1 types should **reserve space** for bindings even if the implementation is deferred: +Reserve optional fields in the v1 types. These cost nothing — they're ignored by `toRawInput()` until binding support is implemented. But they ensure FieldSets and QueryBuilders created now can carry `.as()` declarations that activate later. ```ts class PropertyPath { - readonly steps: PropertyShape[]; - readonly rootShape: NodeShape; - readonly bindingName?: string; // ← reserved for .as() - - as(name: string): PropertyPath { - return new PropertyPath(this.steps, this.rootShape, name); - } + readonly bindingName?: string; // reserved for .as() + as(name: string): PropertyPath { ... } + matches(name: string): PropertyPath { return this.as(name); } // sugar } type FieldSetEntry = { path: PropertyPath; alias?: string; scopedFilter?: WhereCondition; - bindingName?: string; // ← reserved: exported binding - joinBinding?: string; // ← reserved: consumed binding + bindingName?: string; // reserved: .as() on this entry }; type WhereConditionValue = | string | number | boolean | Date | NodeReferenceValue - | { $ref: string }; // ← reserved: binding reference + | { $ref: string }; // reserved: binding reference -// QueryBuilder internal state class QueryBuilder { - private _bindings: Map; // ← reserved - // ... + private _bindings: Map; // reserved } ``` -This costs nothing in v1 — the fields are optional, ignored by `toRawInput()` until binding support is implemented. But it means FieldSets created now can carry `.as()` declarations that "just work" when bindings land. - -#### What needs to change in the IR for bindings - -Not much. The core idea: when two paths declare the same binding name, `LoweringContext` gives them the same alias → same SPARQL variable. - -``` -Today (no bindings): - person → bestFriend → a1 → favoriteHobby → a2 ?a2 = ?hobby1 - person → hobbies → a3 ?a3 = ?hobby2 (different!) - -With bindings: - person → bestFriend → a1 → favoriteHobby → a2 a2 is named 'hobby' - person → hobbies → a2 reuses a2 → same ?variable! -``` - -The change to `LoweringContext` is one new map: - -```ts -class LoweringContext { - private namedBindings = new Map(); // bindingName → alias - - getOrCreateTraversal(from: string, property: string, bindingName?: string): string { - // If this traversal endpoint has a binding name, register or reuse it - if (bindingName) { - if (this.namedBindings.has(bindingName)) { - // Another path already claimed this name → reuse the same alias - return this.namedBindings.get(bindingName); - } - const alias = this.nextAlias(); - this.namedBindings.set(bindingName, alias); - // ... create traverse pattern as normal - return alias; - } - // ... existing dedup logic unchanged - } - - resolveBinding(name: string): string { - const alias = this.namedBindings.get(name); - if (!alias) throw new Error(`Unknown binding: ${name}`); - return alias; - } -} -``` - -The change to `IRTraversePattern` is one optional field: - -```ts -type IRTraversePattern = { - kind: 'traverse'; - from: IRAlias; - to: IRAlias; - property: string; - filter?: IRExpression; - bindingName?: string; // ← new: names this endpoint for reuse -}; -``` +**QueryBuilder string API** (also reserved for later): +- `.bind('name', 'path')` — label the endpoint of a path +- `.constrain('path', 'name')` — constrain a path's endpoint to match a named binding -Everything downstream (`irToAlgebra`, `algebraToString`) already works with aliases.

Extend/omit/pick create new arrays. But the entries themselves reference PropertyShapes (which are mutable objects in the current codebase). Should FieldSet deep-freeze its entries? Or is it sufficient that the FieldSet *array* is new (so you can't accidentally mutate the list), while PropertyShape references are shared? Probably the latter — PropertyShapes are effectively singletons registered on NodeShapes. -11. **Shared variable bindings — see dedicated section above** ("Variable reuse and shared bindings") for detailed API options, open questions (scope, validation, multiple exporters, cross-shape, OPTIONAL semantics, serialization, naming), and IR changes. +11. **Shared variable bindings** — moved to [008-shared-variable-bindings.md](./008-shared-variable-bindings.md). For 003, just reserve optional `bindingName` fields in v1 types (see "forward-compatibility" section above). 12. **ShapeAdapter property format — string vs reference resolution:** When the adapter `properties` map uses strings, the string is resolved as a property label on the respective shape (`from` shape for keys, `to` shape for values). When the adapter uses `{id: someIRI}` references, those are used directly. But what about dotted paths like `'address.city'`? These imply chained resolution: first resolve `address` on the `from` shape, then `city` on `address`'s valueShape. The target side similarly resolves `'address.addressLocality'` step by step. This makes dotted path mapping work, but should the adapter also support structural differences where one shape has a flat property and the other has a nested path? (e.g. `'city'` → `'address.addressLocality'`). Probably yes, but that's a later extension. diff --git a/docs/ideas/008-shared-variable-bindings.md b/docs/ideas/008-shared-variable-bindings.md new file mode 100644 index 0000000..a476ccd --- /dev/null +++ b/docs/ideas/008-shared-variable-bindings.md @@ -0,0 +1,398 @@ +--- +summary: Shared variable bindings — let multiple property paths end at the same SPARQL variable via `.as()` naming, enabling structural joins without FILTER. +packages: [core] +depends_on: [003-dynamic-ir-construction] +--- + +# Shared Variable Bindings + +## Status: design + +## Problem + +Some queries need **two different property paths to end at the same node**.

charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 3a — FieldSet: - Immutable composable collection of PropertyPaths for shape field selection - Static constructors: for() (string/callback/PropertyPath), all(), merge() - Composition: select(), add(), remove(), set(), pick() - Nesting support via object form: { friends: ['name', 'hobby'] } - Integrated with QueryBuilder via .select(fieldSet) and .fields() Phase 3b — Mutation builders: - CreateBuilder: immutable fluent builder for create mutations with .set()/.withId() - UpdateBuilder: immutable fluent builder with .for()/.set(), guards on missing target - DeleteBuilder: immutable builder for delete mutations - All implement PromiseLike for await-triggered execution - All delegate to existing factories for identical IR generation Tests: 39 new tests (544 total passing), IR equivalence verified against DSL. https://claude.ai/code/session_01JCtsSZg1vcWZ5jzhgH4TYy --- jest.config.js | 2 + src/index.ts | 17 ++ src/queries/CreateBuilder.ts | 136 +++++++++++++++ src/queries/DeleteBuilder.ts | 108 ++++++++++++ src/queries/FieldSet.ts | 271 +++++++++++++++++++++++++++++ src/queries/QueryBuilder.ts | 39 ++++- src/queries/UpdateBuilder.ts | 142 +++++++++++++++ src/tests/field-set.test.ts | 195 +++++++++++++++++++++ src/tests/mutation-builder.test.ts | 246 ++++++++++++++++++++++++++ 9 files changed, 1150 insertions(+), 6 deletions(-) create mode 100644 src/queries/CreateBuilder.ts create mode 100644 src/queries/DeleteBuilder.ts create mode 100644 src/queries/FieldSet.ts create mode 100644 src/queries/UpdateBuilder.ts create mode 100644 src/tests/field-set.test.ts create mode 100644 src/tests/mutation-builder.test.ts diff --git a/jest.config.js b/jest.config.js index d425e39..3f4c6c9 100644 --- a/jest.config.js +++ b/jest.config.js @@ -27,6 +27,8 @@ module.exports = { '**/sparql-negative.test.ts', '**/sparql-fuseki.test.ts', '**/query-builder.test.ts', + '**/field-set.test.ts', + '**/mutation-builder.test.ts', ], testPathIgnorePatterns: ['/old/'], transform: { diff --git a/src/index.ts b/src/index.ts index 41ff537..365f82d 100644 --- a/src/index.ts +++ b/src/index.ts @@ -40,6 +40,10 @@ import * as Sparql from './sparql/index.js';

These should verify that `Awaited p.name)>` resolves to the same types as the DSL path. Result types must stay **identical** — how types are generated internally is free to change, but the resolved types consumers see must not change. -- Example smoke tests to add to a new `query-builder.types.test.ts` (compile-only, `describe.skip`): +- New `query-builder.types.test.ts` (compile-only, `describe.skip`) mirroring key patterns from `query.types.test.ts`: ```ts test('select literal property', () => { const promise = QueryBuilder.from(Person).select(p => p.name); @@ -790,9 +814,47 @@ private clone( const single = null as unknown as Result; expectType(single.name); }); + test('select with chaining preserves types', () => { + const promise = QueryBuilder.from(Person) + .select(p => [p.name, p.friends]) + .where(p => p.name.equals('x')) + .limit(5); + type Result = Awaited; + const first = (null as unknown as Result)[0]; + expectType(first.name); + expectType(first.friends[0].id); + }); + test('sub-select', () => { + const promise = QueryBuilder.from(Person).select(p => + p.friends.select(f => ({name: f.name, hobby: f.hobby})), + ); + type Result = Awaited; + expectType((null as unknown as Result)[0].friends[0].name); + }); + test('count', () => { + const promise = QueryBuilder.from(Person).select(p => p.friends.size()); + type Result = Awaited; + expectType((null as unknown as Result)[0].friends); + }); + test('date type', () => { + const promise = QueryBuilder.from(Person).select(p => p.birthDate); + type Result = Awaited; + expectType((null as unknown as Result)[0].birthDate); + }); + test('boolean type', () => { + const promise = QueryBuilder.from(Person).select(p => p.isRealPerson); + type Result = Awaited; + expectType((null as unknown as Result)[0].isRealPerson); + }); + test('string path — no type inference (any)', () => { + const promise = QueryBuilder.from('my:PersonShape').select(['name']); + type Result = Awaited; + // Result is any — string-based construction has no type inference + expectType(null as unknown as Result); + }); ``` -**Risk:** The `QueryResponseToResultType` conditional type is complex and may not resolve cleanly when the `R` generic is still abstract. If this happens, fall back to keeping `Result = any` at the QueryBuilder level and only resolve types when `Shape.select()` provides concrete types (in 4.4b). This fallback still means the DSL result types stay identical — only the direct QueryBuilder API would lose types. The DSL types must NEVER regress. +**Risk (largely mitigated):** Type probe confirms `QueryResponseToResultType` resolves correctly through class generics and `Awaited`. The incremental 6-step approach means any step that fails can be diagnosed in isolation without rolling back prior steps.

The conditional type `T extends FieldSet` will match actual FieldSet instances. This is correct since after 12c, `.select()` returns real FieldSets. + +2. **`getQueryPaths()` and `parentQueryPath`** — These are currently on SubSelectResult but not on FieldSet. Phase 12c must add them (either as methods/getters or stored properties) so that existing code in `BoundComponent`, `isSubSelectResult` duck-checks, and `fieldSetToSelectPath` continues to work. FieldSet already has `entries` which can produce query paths via `fieldSetToSelectPath()`, so `getQueryPaths()` can be a computed method. + +3. **`traceResponse` field** — SubSelectResult stores `traceResponse` (the raw callback return). FieldSet currently doesn't store this — it processes it into entries during construction. For the phantom `__response` type to work, we don't need the runtime value, just the `declare` field. But `extractSubSelectEntriesPublic` uses `traceResponse` at runtime. Two options: + - Store `traceResponse` on FieldSet (adds runtime field) + - Process it eagerly during `forSubSelect()` construction (cleaner — no raw trace needed after construction) + + **Recommendation:** Process eagerly. The FieldSet already processes the trace into entries in `for()`, so `forSubSelect()` should do the same. + +4. **Duck-type check in FieldSet.ts** — `isSubSelectResult()` checks for `getQueryPaths` and `parentQueryPath`. After 12c, sub-selects return FieldSet instances. The duck-type check should be updated to `obj instanceof FieldSet` (possible since FieldSet.ts owns the class) or kept as structural check with updated comment. + +5. **Backward compatibility** — The deprecated `SelectQueryFactory` alias can be updated to point to `FieldSet` with matching generics: `type SelectQueryFactory = FieldSet`. Shape parameter `S` is lost but may be acceptable for deprecated usage.

All 20 probes compile cleanly. Key finding: the type system handles 3+ levels of .select() nesting correctly. Custom object keys wrapping sub-selects use the source property name (e.g. bestFriend) rather than the user's alias key — documented as expected behavior. https://claude.ai/code/session_01JCtsSZg1vcWZ5jzhgH4TYy --- src/test-helpers/query-fixtures.ts | 85 +++++++ src/tests/query.types.test.ts | 105 +++++++++ src/tests/type-probe-deep-nesting.ts | 332 +++++++++++++++++++++++++++ 3 files changed, 522 insertions(+) create mode 100644 src/tests/type-probe-deep-nesting.ts diff --git a/src/test-helpers/query-fixtures.ts b/src/test-helpers/query-fixtures.ts index d1cdf02..4ed0492 100644 --- a/src/test-helpers/query-fixtures.ts +++ b/src/test-helpers/query-fixtures.ts @@ -357,4 +357,89 @@ export const queryFactories = { queryBuilderPreload: () => QueryBuilder.from(Person).select((p) => [p.name]).preload('bestFriend', componentLike), selectAllEmployeeProperties: () => Employee.selectAll(), + + // --- Deep nesting boundary tests (Phase 12 validation) --- + + // Triple-nested sub-selects: 3 levels of .select() + tripleNestedSubSelect: () => + Person.select((p) => + p.friends.select((f) => + f.bestFriend.select((bf) => + bf.friends.select((ff) => ({name: ff.name, hobby: ff.hobby})), + ), + ), + ), + + // Double nested: singular → plural + doubleNestedSingularPlural: () => + Person.select((p) => + p.bestFriend.select((bf) => + bf.friends.select((f) => ({name: f.name, hobby: f.hobby})), + ), + ), + + // Double nested: plural → singular + doubleNestedPluralSingular: () => + Person.select((p) => + p.friends.select((f) => + f.bestFriend.select((bf) => ({name: bf.name, isReal: bf.isRealPerson})), + ), + ), + + // Sub-select returning array of paths (not custom object) + subSelectArrayOfPaths: () => + Person.select((p) => + p.friends.select((f) => [f.name, f.hobby, f.birthDate]), + ), + + // Sub-select on singular returning array of paths + subSelectSingularArrayPaths: () => + Person.select((p) => + p.bestFriend.select((bf) => [bf.name, bf.hobby, bf.isRealPerson]), + ), + + // Sub-select with count in custom object + subSelectWithCount: () => + Person.select((p) => + p.friends.select((f) => ({ + name: f.name, + numFriends: f.friends.size(), + })), + ), + + // Mixed: plain path + sub-select in array + mixedPathAndSubSelect: () => + Person.select((p) => [ + p.name, + p.friends.select((f) => ({name: f.name, hobby: f.hobby})), + ]), + + // Multiple sub-selects in array + multipleSubSelectsInArray: () => + Person.select((p) => [ + p.friends.select((f) => ({name: f.name})), + p.bestFriend.select((bf) => ({hobby: bf.hobby})), + ]), + + // Sub-select + one() unwrap + subSelectWithOne: () => + Person.select((p) => + p.friends.select((f) => ({name: f.name, hobby: f.hobby})), + ) + .where((p) => p.equals(entity('p1'))) + .one(), + + // selectAll() on sub-select plural + subSelectAllPlural: () => + Person.select((p) => p.friends.selectAll()), + + // selectAll() on sub-select singular + subSelectAllSingular: () => + Person.select((p) => p.bestFriend.selectAll()), + + // Employee sub-select (inheritance) + employeeSubSelect: () => + Employee.select((e) => + e.bestFriend.select((bf) => ({name: bf.name, dept: bf.department})), + ), };

This section captures what's good, what's concerning, and what's bad in the current type system state. + +### What's Good + +- **Phantom types in FieldSet** — `declare readonly __response: R` carries type info with zero runtime cost. Clean pattern. +- **Proxy-based path tracing** — `ProxiedPathBuilder.ts` cleanly captures `p.friends.bestFriend.name` chains. +- **QueryBuilder generic flow** — `S` (shape), `R` (response), `Result` stay consistent through `.select()`, `.one()`, `.where()`, `.limit()`. +- **PromiseLike integration** — `await builder` works without losing types. +- **Type probe tests** — `type-probe-4.4a.ts` and `type-probe-deep-nesting.ts` cover 4+ levels of nesting, sub-selects, custom objects, inheritance. Solid coverage. + +### What's Concerning + +- **CreateQResult** (SelectQuery.ts:415–493) — 12+ levels of conditional nesting. There's a TODO comment saying "this must be simplified and rewritten" and "likely the most complex part of the type system". It recursively self-calls. +- **GetQueryObjectResultType** (SelectQuery.ts:324–370) — 10+ conditional branches. Hard to trace. +- **Silent `never` fallthrough** — `QueryResponseToResultType`, `GetQueryObjectResultType`, `ToQueryPrimitive` all end with `: never`. If a type doesn't match any branch, it silently becomes `never` instead of giving a useful error. +- **QResult's second generic** — `QResult` is completely unconstrained. Any garbage object type gets merged in. +- **Generic naming** — mostly consistent (`S`, `R`, `Source`, `Property`) but `QShapeType` vs `ShapeType` vs `T` appear inconsistently in the conditional types. + +### What's Bad + +- **~44 `as any` casts in production code** — the biggest cluster is `Shape.ts` (10 casts for static method factory bridging) and `SelectQuery.ts` (20+ casts for proxy construction, generic coercion, shape instantiation). + - **Root cause:** `ShapeType` (the class constructor type) and `typeof Shape` (the abstract base) don't align. Every `Shape.select()`, `Shape.update()`, `Shape.create()`, `Shape.delete()` starts with `this as any`. This is the single biggest type gap. +- **IRDesugar shape resolution** — `(query.shape as any)?.shape?.id` because `RawSelectInput.shape` is typed as `unknown`. The runtime value is actually always a `ShapeType` or `NodeShape`. + +### Commented-Out Dead Code (still present) + +| Location | What | +|---|---| +| SelectQuery.ts:1365–1370 | Old `where()` method | +| SelectQuery.ts:1402–1428 | Old property resolution, TestNode, convertOriginal | +| SelectQuery.ts:733–746 | Abandoned TestNode approach | +| SelectQuery.ts:1441, 1462 | Debug `console.error`, old proxy return | +| SelectQuery.ts:1729–1740 | Old countable logic | +| MutationQuery.ts:266–269 | Commented validation | +| ShapeClass.ts:137–161 | `ensureShapeConstructor()` entirely commented out | + +### Incomplete Features (TODOs) + +| Location | What | +|---|---| +| MutationQuery.ts:33 | "Update functions not implemented yet" | +| QueryContext.ts:8 | "should return NullQueryShape" | +| SelectQuery.ts:693–697 | Async shape loading | +| SelectQuery.ts:1615–1616 | Consolidate QueryString/Number/Boolean/Date into QueryPrimitive | + +--- + +## Proposed Phases: Type System Cleanup + +### Phase 13: Dead Code Removal + +**Effort: Low | Impact: Clarity** + +Remove all commented-out dead code identified in the review.

This matches the natural decision points in the conditional. +2. **Should `GetQueryObjectResultType` be simplified in the same phase?** It has 10+ branches and is closely related. **Recommendation:** Yes, tackle both together — they share the same decomposition pattern and the type probes test them jointly. + +--- + +### Phase 17: getQueryPaths Monkey-Patch Cleanup + +**Effort: Medium | Impact: Code health, enables Phase 18** + +Factor the `getQueryPaths` monkey-patch into the FieldSet class properly.

Eagerly (store in constructor) avoids repeat computation. **Recommendation:** Lazily — `getQueryPaths()` is called at most once per FieldSet, and computing from entries is cheap. No need to store extra state. +2. **Keep `getQueryPaths` on QueryBuilder too?** QueryBuilder.ts:366 has its own `getQueryPaths()`. After this phase, should it delegate to `this.fields().getQueryPaths()`? **Recommendation:** Yes — single source of truth.

After this phase, QueryBuilder won't need it, but it may still be useful for debugging/inspection. **Recommendation:** Deprecate with `@deprecated` JSDoc — keep available but mark for future removal. Remove from QueryBuilder's imports. +2. **New function name: `desugarFieldSetQuery` or overload `desugarSelectQuery`?** An overload keeps one entry point. A new function is clearer about the two code paths. **Recommendation:** New function `desugarFieldSetQuery()` — clearer separation, easier to trace, and the old function stays untouched for backward compat. +3. **Should FieldSet carry `where`, `sortBy`, `limit`, `offset` directly?** Currently these live on QueryBuilder, not FieldSet. The new `RawFieldSetInput` still needs these from QueryBuilder. **Recommendation:** Keep them on QueryBuilder for now — FieldSet is the "what to select", QueryBuilder is the "how to query". Don't conflate concerns. --- -### Future TODO (out of scope for now) +### Phase 19: Shape Factory Redesign + `as any` Reduction + +**Effort: High | Impact: Type safety — addresses root cause of ~44 `as any` casts** + +The root cause: `ShapeType` (a class constructor `{ new(...args): S }`) and `typeof Shape` (the abstract base with static methods) don't align.

charset=UTF-8 Content-Transfer-Encoding: 8bit Define ShapeConstructor — a concrete (non-abstract) constructor type that includes static properties (shape, targetClass). Use it as: - The `this` parameter in all Shape static methods (select, selectAll, update, create, delete, mapPropertyShapes, getSetOf) - The shape field type in all Builders and their Init interfaces - The parameter type in mutation factory constructors - The parameter type in resolveShape, createProxiedPathBuilder, evaluateSortCallback, and FieldSet methods This eliminates the root cause of most `as any` casts: the mismatch between ShapeType (abstract new) and what runtime code needs (concrete new + static property access). Cast count: ~44 → ~31 in query files + Shape.ts. Remaining casts are inherent to proxy/dynamic patterns (callback generics, dynamic property access by string key). https://claude.ai/code/session_01P1bPzwN55G6NHXVH1dDQpV --- docs/plans/001-dynamic-queries.md | 73 +++++++------ src/queries/CreateBuilder.ts | 18 ++-- src/queries/CreateQuery.ts | 4 +- src/queries/DeleteBuilder.ts | 10 +- src/queries/DeleteQuery.ts | 4 +- src/queries/FieldSet.ts | 25 ++--- src/queries/ProxiedPathBuilder.ts | 6 +- src/queries/QueryBuilder.ts | 20 ++-- src/queries/SelectQuery.ts | 6 +- src/queries/UpdateBuilder.ts | 10 +- src/queries/UpdateQuery.ts | 4 +- src/queries/resolveShape.ts | 10 +- src/shapes/Shape.ts | 165 ++++++++++++++++-------------- 13 files changed, 190 insertions(+), 165 deletions(-) diff --git a/docs/plans/001-dynamic-queries.md b/docs/plans/001-dynamic-queries.md index cfc1039..a962bfa 100644 --- a/docs/plans/001-dynamic-queries.md +++ b/docs/plans/001-dynamic-queries.md @@ -3535,52 +3535,59 @@ Remove all dead code from the old IR layer. **Effort: High | Impact: Type safety — addresses root cause of ~44 `as any` casts** -The root cause: `ShapeType` (a class constructor `{ new(...args): S }`) and `typeof Shape` (the abstract base with static methods) don't align.

Change getShapeClass() return type from `typeof Shape` to `ShapeConstructor | undefined` — eliminates `as unknown as ShapeConstructor` casts at call sites (resolveShape.ts, FieldSet.ts) and removes `as any` casts for `new shapeClass()` (SelectQuery.ts). 2. Update FieldSet.resolveShapeInput() to look up ShapeConstructor from NodeShape via getShapeClass(), so NodeShape callers get the full ProxiedPathBuilder proxy (sub-selects, .size(), evaluations, etc.) instead of the limited string-only fallback. 3.

Create them, compose them, and feed them into queries. + +**Creating a FieldSet:** +```typescript +import {FieldSet} from '@_linked/core'; + +// From a Shape class with string field names +const fs = FieldSet.for(Person, ['name', 'knows']); + +// From a Shape class with a type-safe callback +const fs = FieldSet.for(Person, p => [p.name, p.knows]); + +// From a shape IRI string (when you only have the shape's IRI) +const fs = FieldSet.for('https://schema.org/Person', ['name', 'knows']); + +// Select all decorated properties +const allFields = FieldSet.all(Person); + +// Select all properties with depth (includes nested shapes) +const deep = FieldSet.all(Person, {depth: 2}); +``` + +**Nested fields:** +```typescript +// Dot-separated paths for nested properties +const fs = FieldSet.for(Person, ['name', 'knows.name']); + +// Object form for nested sub-selections +const fs = FieldSet.for(Person, [{knows: ['name', 'hobby']}]); +``` + +**Composing FieldSets:** +```typescript +const base = FieldSet.for(Person, ['name']); + +// Add fields +const extended = base.add(['knows', 'birthDate']); + +// Remove fields +const minimal = extended.remove(['birthDate']); + +// Pick specific fields +const picked = extended.pick(['name', 'knows']); + +// Merge multiple FieldSets +const merged = FieldSet.merge([fieldSet1, fieldSet2]); +``` + +**Inspecting a FieldSet:** +```typescript +const fs = FieldSet.for(Person, ['name', 'knows']); +fs.labels(); // ['name', 'knows'] +fs.paths(); // [PropertyPath, PropertyPath] +``` + +**Use cases:** + +```typescript +// CMS: user picks fields from a UI +const fields = FieldSet.for(Person, userSelectedFields); +const results = await QueryBuilder.from(Person).select(fields); + +// API gateway: accept fields as query parameters +const fields = FieldSet.for(Person, req.query.fields.split(',')); +const results = await QueryBuilder.from(Person).select(fields); + +// Component composition: merge field sets from child components +const merged = FieldSet.merge([headerFields, sidebarFields, contentFields]); +const results = await QueryBuilder.from(Person).select(merged); + +// Progressive loading: start minimal, add detail on demand +const summary = FieldSet.for(Person, ['name']); +const detail = summary.add(['email', 'knows', 'birthDate']); +``` + +### Mutation Builders + +The mutation builders are the programmatic equivalent of `Person.create(...)`, `Person.update(...)`, and `Person.delete(...)`. They accept Shape classes or shape IRI strings. + +```typescript +import {CreateBuilder, UpdateBuilder, DeleteBuilder} from '@_linked/core'; + +// Create — equivalent to Person.create({name: 'Alice'}) +const created = await CreateBuilder.from(Person) + .set({name: 'Alice'}) + .withId('https://my.app/alice'); + +// Update — equivalent to Person.update({id: '...'}, {name: 'Alicia'}) +const updated = await UpdateBuilder.from(Person) + .for({id: 'https://my.app/alice'}) + .set({name: 'Alicia'}); + +// Delete — equivalent to Person.delete({id: '...'}) +const deleted = await DeleteBuilder.from(Person, {id: 'https://my.app/alice'}); + +// All builders are PromiseLike — await them or call .build() for the IR +const ir = CreateBuilder.from(Person).set({name: 'Alice'}).build(); +``` + +### JSON Serialization + +Queries and FieldSets can be serialized to JSON and reconstructed — useful for saving query configurations, sending them over the wire, or building query editor UIs. + +```typescript +// Serialize a QueryBuilder +const query = QueryBuilder.from(Person) + .select(p => [p.name, p.knows]) + .where(p => p.name.equals('Semmy')); + +const json = query.toJSON(); +// json is a plain object — store it, send it, etc. + +// Reconstruct from JSON +const restored = QueryBuilder.fromJSON(json); +const results = await restored; + +// FieldSet serialization works the same way +const fs = FieldSet.for(Person, ['name', 'knows']); +const fsJson = fs.toJSON(); +const restoredFs = FieldSet.fromJSON(fsJson); +``` + +Example JSON output for `QueryBuilder.from(Person).select(p => p.name).toJSON()`: +```json +{ + "shape": "https://schema.org/Person", + "fields": [{"path": "name"}] +} +``` + ## TODO - Allow `preloadFor` to accept another query (not just a component).

No new pipeline stages were needed. + +### Key Design Decisions + +**1. DSL and QueryBuilder are the same system.** +The DSL is syntactic sugar. `Person.select(p => [p.name])` internally creates a `QueryBuilder`, which holds a `FieldSet`. One shared `ProxiedPathBuilder` proxy implementation powers both paths. + +**2. Immutable builders, PromiseLike execution.** +Every `.where()`, `.select()`, `.limit()`, etc. returns a new builder (shallow clone). `QueryBuilder implements PromiseLike` so `await` triggers execution. No `nextTick`, no mutable state, no `PatchedQueryPromise`. + +**3. FieldSet as the canonical query primitive.** +FieldSet is a named, immutable, serializable collection of `FieldSetEntry` objects rooted at a shape. Entries carry property paths, scoped filters, sub-selects, aggregations, evaluations, and preloads. All query information flows through FieldSet before reaching the IR pipeline. + +**4. Direct FieldSet-to-desugar conversion.** +Phase 18 eliminated the `SelectPath` / `QueryPath` intermediate representation. `desugarSelectQuery()` accepts FieldSet entries directly via `RawSelectInput.entries`, removing the `fieldSetToSelectPath()` bridge that had been used as an intermediate step. + +**5. Targeting via `.for()` / `.forAll()`.** +`.for(id)` sets a single subject (implies `singleResult`). `.forAll(ids?)` generates a `VALUES ?subject { ... }` clause for multi-ID filtering. Both accept `string | NodeReferenceValue`. Mutually exclusive — calling one clears the other. + +**6. Mutation builders follow the same pattern.** +`CreateBuilder`, `UpdateBuilder`, `DeleteBuilder` are immutable, PromiseLike, and delegate to existing `MutationQueryFactory.convertUpdateObject()` for input normalization. `UpdateBuilder` requires `.for(id)` before execution (enforced at runtime with a guard). + +**7. `toRawInput()` bridges to the existing pipeline.** +QueryBuilder produces `RawSelectInput` — the same structure the old proxy tracing produced. The existing `buildSelectQuery()` → IRDesugar → IRCanonicalize → IRLower → irToAlgebra chain is reused unchanged. + +### Resolved Design Decisions + +- **Scoped filter merging** — AND by default. OR support deferred. +- **Immutability implementation** — shallow clone with structural sharing deferred unless benchmarks show need. +- **SelectPath elimination** — Phase 18 implemented direct FieldSet-to-desugar conversion, removing the SelectPath roundtrip that was the last legacy bridge. +- **SubSelectResult elimination** — Phase 12 replaced the type-only `SubSelectResult` interface with `FieldSet` phantom generics, unifying runtime and type representations. + +--- + +## 3.

The largest clusters are in `Shape.ts` (static method factory bridging where `this` type doesn't align with `ShapeConstructor`) and `SelectQuery.ts` (proxy construction, generic coercion). These are inherent to the proxy/dynamic pattern and would require deeper type system work to eliminate. + +### `traceFieldsFromCallback` Fallback + +The old simple proxy fallback in `FieldSet.ts` still exists for NodeShape-only paths where no `ShapeClass` can be resolved. The `ProxiedPathBuilder` is the primary path for all ShapeClass-aware construction. + +### CreateQResult Type Complexity + +`CreateQResult` (SelectQuery.ts) has 12+ levels of conditional nesting with recursive self-calls. Deferred to a separate effort (`docs/ideas/011-query-type-system-refactor.md`) because the types are stable and well-tested by type probes. Risk of silently breaking inference outweighs readability benefit. + +### Type Inference Scope + +Result type inference only works when `QueryBuilder.from(ShapeClass)` receives a TypeScript class. When using a string IRI (`QueryBuilder.from('my:PersonShape')`), `S` defaults to `Shape` and result types degrade to `any`. This is by design — the string path is for runtime/CMS use where types are not known at compile time. + +### Deferred Features + +| Item | Status | +|------|--------| +| Callback-style mutation updates (`Shape.update(entity, e => { e.name = 'Bob' })`) | Not implemented — UpdateBuilder handles object-style updates.

In DSL callbacks and in QueryBuilder/FieldSet callbacks, you get the same proxy with the same methods. `.path('string')` is an escape hatch on the proxy for when the path comes from runtime data: - -```ts -// These use the same proxy, same PathBuilder, same code: -Person.select(p => [p.name, p.hobbies.select(h => [h.label])]) -FieldSet.for(PersonShape, p => [p.name, p.hobbies.select(h => [h.label])]) -QueryBuilder.from(PersonShape).select(p => [p.name, p.hobbies.select(h => [h.label])]) - -// .path() is an escape hatch for dynamic strings — available on the same proxy: -Person.select(p => [p.name, p.path(dynamicField)]) -FieldSet.for(PersonShape, p => [p.name, p.path(dynamicField)]) -``` - -This means: -- **One proxy implementation** shared between DSL and dynamic builder -- Every DSL feature (`.select()` for sub-selection, `.where()` for scoped filters, `.as()` for bindings) works in QueryBuilder callbacks too -- String forms on QueryBuilder (`.select(['name'])`, `.where('age', '>', 18)`) are convenience shortcuts that produce the same internal structures - -### Current DSL: `.select()` vs `.query()` — and the execution model - -The DSL currently has two entry points: -- **`Person.select(p => ...)`** — executes immediately via `nextTick`, returns `PatchedQueryPromise` (a Promise with chainable `.where()`, `.limit()`, `.sortBy()`, `.one()` that mutate the underlying factory before the tick fires) -- **`Person.query(p => ...)`** — returns a `SelectQueryFactory` (deferred, not executed until `.build()` is called) - -**Decided: PromiseLike execution model.** QueryBuilder implements `PromiseLike`. No more `nextTick` hack. The chain is evaluated synchronously (each method returns a new immutable builder), and execution happens only when `.then()` is called (which `await` does automatically): - -```ts -class QueryBuilder implements PromiseLike { - then(onFulfilled?, onRejected?): Promise { - return this.exec().then(onFulfilled, onRejected); - } -} - -// Await triggers execution (PromiseLike) -const result = await QueryBuilder.from(PersonShape).select((p) => [p.name]).where((p) => p.age.gt(18)); - -// Same thing via DSL sugar -const result = await Person.select(p => [p.name]).where(p => p.age.gt(18)); - -// Deferred — no await, just a builder -const builder = Person.query(p => [p.name]).where(p => p.age.gt(18)); -const result = await builder; // execute when ready -const result = await builder.exec(); // explicit alternative -``` - -This means: -- `Person.select(...)` returns a QueryBuilder (PromiseLike). Backward compatible — existing `await Person.select(...)` still works. -- `Person.query(...)` also returns a QueryBuilder. Both return the same type. `.query()` is just a signal of intent ("I'll execute this later"). -- `.where()`, `.limit()`, etc. are immutable (return new builder), not mutable.

Cleaner internals. -- `.exec()` is available for explicit execution without `await`. - -**Decided**: The DSL adopts the `.for(id)` / `.forAll()` chainable pattern instead of passing subjects as arguments. - -```ts -// Chainable .for() — matches QueryBuilder -Person.select(p => [p.name]).for(id) // single ID -Person.select(p => [p.name]).forAll([id1, id2]) // specific list of IDs -Person.select(p => [p.name]).forAll() // all instances -Person.query(p => [p.name]).for(id).exec() // deferred - -// Mutations — .for()/.forAll() required on update (type error without targeting) -Person.update({ age: 31 }).for(id) // single update — .for() required -Person.update({ age: 31 }).forAll([id1, id2]) // update specific list -Person.update({ age: 31 }).forAll() // update all instances - -// Delete — id is a required argument (delete without target makes no sense) -Person.delete(id) // single delete, id required -Person.deleteAll([id1, id2]) // delete specific list -Person.deleteAll() // delete all instances -``` - ---- - -## Proposals - -### Option A: Low-level IR Builder (direct IR construction) - -Expose helper functions that produce `IRSelectQuery` objects directly. No proxy tracing, no desugar/canonicalize/lower — you build the final IR yourself with helpers that reduce boilerplate. - -```ts -import { ir } from 'lincd/queries'; - -const query = ir.select({ - root: ir.shapeScan(PersonShape), // → IRShapeScanPattern - patterns: [ - ir.traverse('a0', 'a1', namePropertyShape), // → IRTraversePattern - ir.traverse('a0', 'a2', friendsPropertyShape), - ir.traverse('a2', 'a3', namePropertyShape), - ], - projection: [ - ir.project('name', ir.prop('a1', namePropertyShape)), - ir.project('friendName', ir.prop('a3', namePropertyShape)), - ], - limit: 10, -}); - -// query is a valid IRSelectQuery — pass to store directly -const results = await store.selectQuery(query); -``` - -**Pros:** Full control. No magic. Easily serializable. Works for any query the IR supports (including future MINUS, CONSTRUCT, etc.). - -**Cons:** Verbose. Alias management is manual. Feels like writing assembly. No type inference on results. - -**Best for:** Migration scripts, code generators, admin tooling, advanced one-offs. - ---- - -### Option B: Mid-level Query Builder (fluent chain API) - -A builder that knows about shapes and property shapes, auto-manages aliases, and produces IR via the existing pipeline. This is the "one layer up" from raw IR — it uses `NodeShape` / `PropertyShape` objects but doesn't require a Shape class or proxy tracing. - -```ts -import { QueryBuilder } from 'lincd/queries'; - -const results = await QueryBuilder - .from(PersonShape) // root shape scan - .select(p => [ // p is a dynamic path builder - p.prop(namePropertyShape), // select name - p.prop(friendsPropertyShape) // traverse to friends - .prop(namePropertyShape), // then select their name - ]) - .where(p => - p.prop(agePropertyShape).gte(18) - ) - .limit(10) - .exec(); -``` - -Under the hood, `.from(PersonShape)` creates a root context. `.prop(propertyShape)` appends a step. The builder produces a `RawSelectInput`-equivalent and feeds it through `buildSelectQuery()`. - -**Pros:** Familiar fluent pattern. Shape-aware (validates property belongs to shape). Auto-alias management. Can leverage existing pipeline passes. Mid-complexity. - -**Cons:** New API surface. Need to design the chain types carefully. Result types would be `ResultRow[]` (no static type inference unless we layer generics). - -**Best for:** CMS-style dynamic queries where you know the shapes at runtime. - ---- - -### Option C: "Dynamic DSL" — runtime shape + property path resolution - -Keep the existing DSL patterns but accept string-based or reference-based shape/property lookups. The API looks almost identical to the static DSL but everything is resolved at runtime. - -```ts -import { DynamicQuery } from 'lincd/queries'; - -// By shape + property shape references (most reliable) -const results = await DynamicQuery - .shape(PersonShape) - .select([ - namePropertyShape, // simple property - [friendsPropertyShape, namePropertyShape], // chained path: friends.name - { hobby: [hobbiesPropertyShape, labelPropertyShape] }, // aliased path - ]) - .where(agePropertyShape, '>=', 18) - .limit(10) - .exec(); - -// Or by string labels (convenient, resolves via shape metadata) -const results = await DynamicQuery - .shape('Person') - .select(['name', 'friends.name', { hobby: 'hobbies.label' }]) - .where('age', '>=', 18) - .exec(); -``` - -Internally this would: -1. Resolve shape name → `NodeShape` -2. Parse property paths (string or reference arrays) → walk `NodeShape.properties` to find each `PropertyShape` -3. Build a `RawSelectInput` from the resolved paths -4. Feed into `buildSelectQuery()` - -**Pros:** Extremely CMS-friendly. Accepts strings (for config files, URL params, user input). Path chains are intuitive (`'friends.name'`). Minimal API surface. - -**Cons:** String resolution adds a lookup cost and error surface. No compile-time type safety (result is `ResultRow[]`). Need to handle ambiguous/missing property names. - -**Best for:** Config-driven CMS queries, REST/GraphQL endpoint generation, admin UIs. - ---- - -### Option D: Hybrid — Extend `SelectQueryFactory` to accept dynamic inputs - -Instead of a new API, extend the existing `SelectQueryFactory` to accept property shapes directly, bypassing proxy tracing. The factory already has all the machinery (`toRawInput()`, `build()`, `exec()`). - -```ts -import { Shape } from 'lincd'; - -// New static method on Shape — mirrors .select() but with explicit property shapes -const results = await Shape.dynamicSelect(PersonShape, { - select: [ - namePropertyShape, - [friendsPropertyShape, namePropertyShape], - ], - where: { - property: agePropertyShape, - operator: '>=', - value: 18, - }, - limit: 10, -}); - -// Or: use the existing factory with a new input mode -const factory = new SelectQueryFactory(PersonShape); -factory.addSelection(namePropertyShape); -factory.addSelection([friendsPropertyShape, namePropertyShape]); -factory.setWhereClause(agePropertyShape, '>=', 18); -factory.setLimit(10); -const results = await factory.exec(); -``` - -**Pros:** Reuses existing `SelectQueryFactory` infrastructure. Minimal new code. Familiar patterns. - -**Cons:** `SelectQueryFactory` is already complex (1800+ lines). Adding more modes increases complexity. May conflict with proxy-based initialization. - -**Best for:** Incremental adoption. Keeps everything in one place. - ---- - -### Option E: Composable Path Objects (standalone, composable, reusable) - -Define a `PropertyPath` value object that can be composed, stored, and reused. Queries are built by combining paths. - -```ts -import { path, select } from 'lincd/queries'; - -// Define reusable paths -const name = path(PersonShape, namePropertyShape); -const friendsName = path(PersonShape, friendsPropertyShape, namePropertyShape); -const age = path(PersonShape, agePropertyShape); - -// Compose into a query -const query = select(PersonShape) - .fields(name, friendsName) - .where(age.gte(18)) - .limit(10); - -const results = await query.exec(); - -// Paths are reusable across queries -const otherQuery = select(PersonShape) - .fields(name) - .where(friendsName.equals('Alice')); -``` - -**Pros:** Maximally composable. Paths are first-class values — store them, pass them around, derive from them. Good for CMS schemas where paths are defined in config. - -**Cons:** New concept (path objects). Need to design path composition carefully (what happens when you extend a path from one shape into another?). - -**Best for:** Schema-driven systems where field selections are defined as data. - ---- - -## Comparison Matrix - -| Concern | A (Raw IR) | B (Fluent Builder) | C (Dynamic DSL) | D (Extend Factory) | E (Path Objects) | -|---|---|---|---|---|---| -| Verbosity | High | Medium | Low | Medium | Low | -| Type safety | None | Partial | None | Partial | Partial | -| Learning curve | Steep | Medium | Low | Low | Medium | -| CMS friendliness | Low | High | Highest | Medium | High | -| String-based input | No | No | Yes | No | No | -| Composability | Manual | Chain only | Limited | Chain only | Excellent | -| New API surface | Small (helpers) | Medium (new class) | Medium (new class) | Small (extends existing) | Medium (new types) | -| Reuses pipeline | No (bypass) | Yes | Yes | Yes | Yes | -| Mutation support | Separate | Could extend | Could extend | Could extend | Separate | - ---- - -## Recommendation for CMS - -**Suggested approach: B + C layered, with E-style composability baked into the core `FieldSet` primitive.** - -Build the fluent builder (B) as the core engine. Layer the string-resolving convenience API (C) on top. But instead of treating composability as a separate concern (Option E), make it a first-class feature of the builder via **`FieldSet`** — a named, reusable, composable collection of selections that any query can use. - -> **Method naming:** QueryBuilder uses `.select(fields)` for initial field selection (creation), `.setFields(fields)` / `.addFields(fields)` / `.removeFields(fields)` for modifying an existing builder's fields. FieldSet uses `.set()` / `.add()` / `.remove()` / `.pick()`. - -Option A (raw IR helpers) can come later as a power-user escape hatch. - ---- - -## Composability: Why, When, and How - -### Shapes define structure. Selections define views. - -SHACL shapes already give you composability of *structure* — `AddressShape` knows its properties, `PersonShape.address` points to `AddressShape`, and `NodeShape.getPropertyShapes(true)` walks the inheritance chain. But your CMS doesn't always want *all* properties of a shape. Different surfaces need different **views** of the same shape: - -| CMS Surface | What it needs from PersonShape | -|---|---| -| **Table overview** | `name`, `email`, `address.city` (summary columns) | -| **Edit form** | All direct properties + nested address fields | -| **Person card component** | `name`, `avatar`, `address.city` (compact display) | -| **Person detail page** | Everything the card needs + `bio`, `age`, `friends.name`, `hobbies.label` | -| **NL chat: "people in Amsterdam"** | `name`, `email` + filter on `address.city` | -| **Drag-drop builder** | Union of whatever each dropped component needs | - -The static DSL handles this fine — each component writes its own `Person.select(p => [...])`. But in a dynamic CMS, those selections aren't hardcoded. They come from: -- **Table column configs** (stored as data: `["name", "email", "address.city"]`) -- **Form field definitions** (derived from shape metadata at runtime) -- **Component data requirements** (each component declares what fields it needs) -- **LLM output** (the chat generates a field list + filter from a prompt) -- **User customization** (user adds/removes columns, reorders fields) - -### The composability problem - -Without a composable primitive, every surface builds its own flat field list. This leads to: - -1. **Duplication** — The PersonCard needs `name + avatar + address.city`. The PersonDetail also needs those, plus more. If you change the card's fields, you have to remember to update the detail page too. - -2. **No query merging** — In the drag-drop builder, a user drops a PersonCard and a HobbyList onto a page. Each component has its own query. Ideally the system merges them into one SPARQL query that fetches everything needed for both. Without a composable selection type, merging is ad-hoc. - -3. **No incremental building** — The NL chat wants to start with "show people" (basic fields), then the user says "also show their hobbies" — you need to extend the selection, not rebuild it from scratch. - -### Solution: `FieldSet` — a composable, reusable selection set - -A `FieldSet` is a named collection of property paths rooted at a shape. It's the E-style path object idea, but designed as a *set of paths* rather than individual paths, because in practice you almost always want a group. - -```ts -import { FieldSet } from 'lincd/queries'; - -// ── Define reusable field sets ────────────────────────────────── - -// A concise summary of a person — used in cards, table rows, autocompletes -const personSummary = FieldSet.for(PersonShape, [ - 'name', - 'email', - 'avatar', -]); - -// Full address — used in forms, detail pages, map components -const fullAddress = FieldSet.for(AddressShape, [ - 'street', - 'city', - 'postalCode', - 'country', -]); - -// Person's address, using a nested FieldSet -const personAddress = FieldSet.for(PersonShape, { - address: fullAddress, // nest: person.address.{street, city, ...} -}); - -// Person card = summary + address city only -const personCard = FieldSet.for(PersonShape, [ - personSummary, // include another FieldSet - 'address.city', // plus one extra path -]); - -// Person detail = card + more -const personDetail = FieldSet.for(PersonShape, [ - personCard, // everything the card needs - 'bio', - 'age', - { friends: personSummary }, // friends, using the same summary view - 'hobbies.label', -]); -``` - -### CMS surface examples - -#### 1. Table overview — columns as FieldSet - -```ts -// Table config (could be stored as JSON, loaded from DB, or user-customized) -const tableColumns = FieldSet.for(PersonShape, [ - 'name', 'email', 'address.city', 'friends.size', -]); - -// Query is one line -const rows = await QueryBuilder - .from(PersonShape) - .select(tableColumns) - .limit(50) - .exec(); - -// User adds a column in the UI → extend the FieldSet -const extendedColumns = tableColumns.add(['age']); -``` - -#### 2. Edit form — shape-derived FieldSet with `all()` - -```ts -// Select ALL properties of the shape (walks getPropertyShapes(true)) -const formFields = FieldSet.all(PersonShape); - -// Or: all direct + expand nested shapes one level -const formFieldsExpanded = FieldSet.all(PersonShape, { depth: 2 }); - -// Use in an update query -const person = await QueryBuilder - .from(PersonShape) - .select(formFields) - .one(personId) - .exec(); -``` - -#### 3. Drag-and-drop builder — merging component requirements - -Each component declares its data requirements as a `FieldSet`. When the user drops components onto a page, the builder merges them. - -```ts -// Component declarations (could be decorators, static props, or metadata) -const personCardFields = FieldSet.for(PersonShape, ['name', 'avatar', 'address.city']); -const hobbyListFields = FieldSet.for(PersonShape, ['hobbies.label', 'hobbies.description']); -const friendGraphFields = FieldSet.for(PersonShape, [ - 'name', - { friends: FieldSet.for(PersonShape, ['name', 'avatar']) }, -]); - -// User drops PersonCard + HobbyList onto a page -// Builder merges their field sets into one query -const merged = FieldSet.merge([personCardFields, hobbyListFields]); -// merged = ['name', 'avatar', 'address.city', 'hobbies.label', 'hobbies.description'] - -const results = await QueryBuilder - .from(PersonShape) - .select(merged) - .exec(); - -// Each component receives the full result and picks what it needs — -// no over-fetching because we only selected the union of what's needed -``` - -#### 4. NL chat — incremental query building - -```ts -// LLM generates initial query spec from "show me people in Amsterdam" -let fields = FieldSet.for(PersonShape, ['name', 'email']); -let query = QueryBuilder - .from(PersonShape) - .select(fields) - .where('address.city', '=', 'Amsterdam'); - -let results = await query.exec(); - -// User: "also show their hobbies" -// LLM extends the existing field set -fields = fields.add(['hobbies.label']); -results = await query.setFields(fields).exec(); - -// User: "only people over 30" -results = await query.where('age', '>', 30).exec(); - -// User: "show this as a detail view" -// Switch to a pre-defined field set (replace fields) -results = await query.setFields(personDetail).exec(); -``` - -#### 5. Shape-level defaults — `shape.all()` / `shape.summary()` - -Since shapes already know their properties, `FieldSet` can derive selections from shape metadata: - -```ts -// All properties of a shape (direct + inherited) -FieldSet.all(PersonShape) -// → ['name', 'email', 'age', 'bio', 'avatar', 'address', 'friends', 'hobbies'] - -// All properties, expanding nested shapes to a given depth -FieldSet.all(PersonShape, { depth: 2 }) -// → ['name', 'email', 'age', 'bio', 'avatar', -// 'address.street', 'address.city', 'address.postalCode', 'address.country', -// 'friends.name', 'friends.email', ..., -// 'hobbies.label', 'hobbies.description'] - -// "Summary" — properties marked with a specific group or order, or a convention -// e.g. properties with order < 5, or a custom 'summary' group -FieldSet.summary(PersonShape) -// → ['name', 'email'] (only the first few ordered properties) -``` - -This is the insight you were getting at: shapes themselves *can* define the field set, and `FieldSet.all(AddressShape)` is effectively the `address.all()` you were imagining. The difference is that `FieldSet` is *detached* from the shape — it's a value you can store, pass around, merge, extend, and serialize. - -### Scoped filters in FieldSets - -A FieldSet entry can carry a **scoped filter** — a condition that applies to a specific traversal, not to the root query. This is the difference between "only active friends" (scoped to the `friends` traversal) and "only people over 30" (top-level query filter). - -```ts -// ── FieldSet with scoped filters ──────────────────────────────── - -// "Active friends" — the filter is part of the reusable field definition -const activeFriends = FieldSet.for(PersonShape, [ - { path: 'friends.name', where: { 'friends.isActive': true } }, - 'friends.email', -]); - -// Equivalently, using the fluent path builder -const activeFriends2 = FieldSet.for(PersonShape, (p) => [ - p.path('friends').where('isActive', '=', true).fields([ - 'name', - 'email', - ]), -]); - -// Using it — the scoped filter travels with the FieldSet -const results = await QueryBuilder - .from(PersonShape) - .select(activeFriends) // friends are filtered to active - .where('age', '>', 30) // top-level: only people over 30 - .exec(); -``` - -This maps naturally to the existing IR — `IRTraversePattern` already has an optional `filter` field. The scoped filter gets lowered into that, while the top-level `.where()` becomes the query-level `IRExpression`. - -**The rule:** Scoped filters on FieldSet entries attach to the traversal they scope. Top-level `.where()` on QueryBuilder attaches to the query root. When FieldSets are merged, scoped filters on the same traversal are AND-combined. - -```ts -// Merging scoped filters -const set1 = FieldSet.for(PersonShape, [ - { path: 'friends.name', where: { 'friends.isActive': true } }, -]); -const set2 = FieldSet.for(PersonShape, [ - { path: 'friends.email', where: { 'friends.age': { '>': 18 } } }, -]); - -const merged = FieldSet.merge([set1, set2]); -// merged friends traversal has: isActive = true AND age > 18 -// merged selections: friends.name + friends.email -``` - -### FieldSet design - -```ts -class FieldSet { - readonly shape: NodeShape; - readonly entries: FieldSetEntry[]; - - // ── Construction ── - static for(shape: NodeShape | string, fields: FieldSetInput[]): FieldSet; - static for(shape: NodeShape | string, fn: (p: ProxiedPathBuilder) => FieldSetInput[]): FieldSet; - static all(shape: NodeShape | string, opts?: { depth?: number }): FieldSet; - static summary(shape: NodeShape | string): FieldSet; - - // ── Composition (all return new FieldSet — immutable) ── - add(fields: FieldSetInput[]): FieldSet; // returns new FieldSet with added fields - remove(fields: string[]): FieldSet; // returns new FieldSet without named fields - set(fields: FieldSetInput[]): FieldSet; // returns new FieldSet with exactly these fields (replaces) - pick(fields: string[]): FieldSet; // returns new FieldSet with only the named fields from existing - static merge(sets: FieldSet[]): FieldSet; // union of multiple FieldSets (deduped, filters AND-combined) - - // ── Introspection ── - paths(): PropertyPath[]; // resolved PropertyPath objects - labels(): string[]; // flat list of dot-paths: ['name', 'address.city'] - toJSON(): FieldSetJSON; // serializable form (for storage/transport) - static fromJSON(json: FieldSetJSON): FieldSet; // deserialize - - // ── Query integration ── - // QueryBuilder.select() / .setFields() / .addFields() accept FieldSet directly -} - -type FieldSetInput = - | string // 'name' or 'address.city' - | PropertyShape // direct reference - | PropertyPath // pre-built path - | FieldSet // include another FieldSet - | ScopedFieldEntry // path + scoped filter - | Record // nested: { 'hobbies': ['label', 'description'] } - | Record; // nested with FieldSet: { 'friends': personSummary } -``` - -#### Nested selection (avoiding path repetition) - -When selecting multiple properties under a deep path, flat strings repeat the prefix: - -```ts -// Repetitive — 'hobbies' appears 3 times -FieldSet.for(PersonShape, [ - 'hobbies.label', - 'hobbies.description', - 'hobbies.category.name', -]); -``` - -Use the nested object form to avoid this. The key is the traversal, the array value is sub-selections relative to that traversal's shape: - -```ts -// Nested — 'hobbies' appears once -FieldSet.for(PersonShape, [ - { 'hobbies': ['label', 'description', 'category.name'] }, -]); - -// Deeper nesting composes: -FieldSet.for(PersonShape, [ - 'name', - { 'friends': [ - 'name', - 'avatar', - { 'hobbies': ['label', 'description'] }, - ]}, -]); -``` - -Both flat and nested forms produce identical FieldSets. The nested form is what `toJSON()` could produce for compact serialization. - -#### Callback form — uses the same proxy as DSL - -The callback form passes a **ProxiedPathBuilder** — the same proxy used in the DSL. Property access (`p.name`) works via proxy. `.path('string')` is an escape hatch for dynamic paths. `.select()` for sub-selection matches the DSL exactly: - -```ts -// Callback form — proxy access, same as DSL -FieldSet.for(PersonShape, (p) => [ - p.name, - p.hobbies.select(h => [h.label, h.description, h.category.name]), -]); - -// Callback form — .path() for dynamic strings, freely mixed with proxy -FieldSet.for(PersonShape, (p) => [ - p.name, - p.path('hobbies').select(h => [h.label, h.path(dynamicField)]), -]); - -// Scoped filter — same as DSL -FieldSet.for(PersonShape, (p) => [ - p.friends.where(f => f.isActive.equals(true)).select(f => [f.name, f.email]), -]); - -// Variable binding -FieldSet.for(PersonShape, (p) => [ - p.bestFriend.favoriteHobby.as('hobby'), - p.hobbies.as('hobby'), -]); -``` - -type ScopedFieldEntry = { - path: string | PropertyPath; - where: WhereConditionInput; // scoped to the traversal in this path -}; - -type FieldSetEntry = { - path: PropertyPath; - alias?: string; // custom result key name - scopedFilter?: WhereCondition; // filter on the deepest traversal -}; -``` - -### When composability matters vs when shapes suffice - -| Situation | Shapes suffice? | FieldSet needed? | -|---|---|---| -| "Show all fields of Address" | Yes — `FieldSet.all(AddressShape)` | Technically uses FieldSet but derives from shape | -| "Table with name, email, city" | No — partial selection across shapes | Yes | -| "Card = summary; Detail = card + more" | No — incremental/layered views | Yes — `add()` | -| "Merge two component requirements" | No — union of partial views | Yes — `merge()` | -| "NL chat adds fields incrementally" | No — runtime extension | Yes — `add()` | -| "Store column config as JSON" | No — need serialization | Yes — `toJSON()`/`fromJSON()` | -| "Form with all editable fields" | Yes — `FieldSet.all(shape)` | Derives from shape, but FieldSet is the API | - -The pattern: **shapes suffice when you want everything. FieldSet is needed when you want a subset, a union, or an evolving view.** - -### Immutability of FieldSets - -Like QueryBuilder, **FieldSets are immutable**. Every `.add()`, `.remove()`, `.set()`, `.pick()` returns a new FieldSet. The original is never modified. - -```ts -const personSummary = FieldSet.for(PersonShape, ['name', 'email']); -const withAge = personSummary.add(['age']); -// personSummary is still ['name', 'email'] -// withAge is ['name', 'email', 'age'] - -const noEmail = personSummary.remove(['email']); -// → ['name'] - -const replaced = personSummary.set(['avatar', 'bio']); -// → ['avatar', 'bio'] — completely replaced - -const nameOnly = withAge.pick(['name']); -// → ['name'] — pick from existing entries -``` - -This matters when the same FieldSet is shared across components. A table extends it with a column — that doesn't affect the card component using the original. - -### Filtering on selected paths - -A path like `age` can be both **selected** and **filtered** — they're independent concerns that happen to touch the same traversal. Under the hood, the IR reuses the same alias for both (via `LoweringContext.getOrCreateTraversal()` which deduplicates `(fromAlias, propertyShapeId)` pairs). So selecting `age` and filtering `age > 30` naturally share a variable — no extra traversal. - -```ts -// FieldSet with age selected AND filtered -const adults = FieldSet.for(PersonShape, [ - 'name', - 'email', - { path: 'age', where: { 'age': { '>=': 18 } } }, - // ↑ selects age AND filters it — same traversal, same ?variable in SPARQL -]); - -// The top-level .where() can ALSO filter on age — they AND-combine -const results = await QueryBuilder - .from(PersonShape) - .select(adults) // has scoped filter: age >= 18 - .where('age', '<', 65) // additional top-level filter: age < 65 - .exec(); -// → SPARQL: WHERE { ... FILTER(?age >= 18 && ?age < 65) } -// → the ?age variable is shared between select, scoped filter, and top-level filter -``` - -This works because the existing pipeline already handles variable deduplication: -- `LoweringContext.getOrCreateTraversal()` returns the same alias when traversing the same `(from, property)` twice -- `VariableRegistry` in `irToAlgebra.ts` maps `(alias, property)` → SPARQL variable name, reusing variables automatically -- A `property_expr` in the projection and a `property_expr` in a where clause that refer to the same `(sourceAlias, property)` resolve to the same `?variable` - -### Variable reuse and shared bindings — forward-compatibility - -> Full design: [008-shared-variable-bindings.md](./008-shared-variable-bindings.md) - -Some SPARQL queries need two property paths to end at the same node (shared variable). Example: "people whose hobbies include their best friend's favorite hobby" — both `bestFriend.favoriteHobby` and `hobbies` must resolve to the same `?hobby` variable. - -The agreed API is **`.as('name')`** — label a path endpoint. If multiple paths use the same name, they share a SPARQL variable. `.matches('name')` is sugar for `.as('name')` (reads better when referencing an existing name). No type checking, no declare/consume distinction, no shape compatibility enforcement. Same name = same variable, period. - -**What v1 must do to prepare:** - -Reserve optional fields in the v1 types. These cost nothing — they're ignored by `toRawInput()` until binding support is implemented. But they ensure FieldSets and QueryBuilders created now can carry `.as()` declarations that activate later. - -```ts -class PropertyPath { - readonly bindingName?: string; // reserved for .as() - as(name: string): PropertyPath { ... } - matches(name: string): PropertyPath { return this.as(name); } // sugar -} - -type FieldSetEntry = { - path: PropertyPath; - alias?: string; - scopedFilter?: WhereCondition; - bindingName?: string; // reserved: .as() on this entry -}; - -type WhereConditionValue = - | string | number | boolean | Date - | NodeReferenceValue - | { $ref: string }; // reserved: binding reference - -class QueryBuilder { - private _bindings: Map; // reserved -} -``` - -**QueryBuilder string API** (also reserved for later): -- `{ path: 'hobbies', as: 'hobby' }` — inline in field entry arrays -- In callback form: `p.hobbies.as('hobby')` — same proxy as DSL, no separate method needed - -**IR change** (when activated): one optional `bindingName?: string` on `IRTraversePattern`, one `Map` on `LoweringContext`. Everything downstream already works with aliases. - ---- - -## Query Derivation, Extension, and Shape Remapping - -Queries need to be **derived** from other queries — not just FieldSets from FieldSets. A QueryBuilder should be a value you can fork, extend, narrow, and remap. - -### Query extension (fork + modify) - -QueryBuilder is immutable-by-default: every modifier returns a new builder. This makes forking natural. - -```ts -// Base query — reusable template -const allPeople = QueryBuilder - .from(PersonShape) - .select(personSummary); - -// Fork for different pages -const peoplePage = allPeople - .limit(20) - .offset(0); - -const activePeople = allPeople - .where('isActive', '=', true); - -const peopleInAmsterdam = allPeople - .where('address.city', '=', 'Amsterdam'); - -// Further fork -const youngPeopleInAmsterdam = peopleInAmsterdam - .where('age', '<', 30) - .setFields(personDetail); // switch view to detail (replace fields) - -// All of these are independent builders — allPeople is unchanged -``` - -This is like a query "prototype chain." Each `.where()`, `.select()`, `.setFields()`, `.addFields()`, `.limit()` returns a new builder that inherits from the parent. Cheap to create (just clone the config), no side effects. - -### Query narrowing (`.one()` / `.for()`) - -```ts -// From a list query to a single-entity query -const personQuery = allPeople; - -// Narrow to a specific person (returns singleResult: true) -const alice = await personQuery.one(aliceId).exec(); - -// Or: narrow to a set of IDs -const subset = await personQuery.for([aliceId, bobId]).exec(); -``` - -### Shape remapping — forward-compatibility - -> Full design: [009-shape-remapping.md](./009-shape-remapping.md) - -Shape remapping lets the same FieldSet/QueryBuilder target a different SHACL shape via declarative `ShapeAdapter` mappings. Components stay portable across ontologies — result keys use original labels, only SPARQL changes. - -**v1 requires no special preparation.** Shape remapping operates on the FieldSet/QueryBuilder public API. As long as `PropertyPath` exposes its `steps` and `rootShape`, and types are immutable/cloneable, the adapter can walk and remap them when it's implemented later. - ---- - -## CMS Surface Examples - -Three real CMS surfaces showing QueryBuilder + FieldSet with decided method names. - -```ts -import { FieldSet, QueryBuilder } from 'lincd/queries';

The proxy `p` in callbacks is the same `ProxiedPathBuilder` used by the DSL. - -### Key internal bridge: `toRawInput()` - -The `QueryBuilder` needs to produce a `RawSelectInput` that the existing pipeline can consume. The trick is that `RawSelectInput.select` expects `SelectPath` — which is `QueryPath[] | CustomQueryObject`. A `QueryPath` is an array of `QueryStep` objects, where each step has a `.property` (PropertyShape). - -This means `QueryBuilder.toRawInput()` can produce the same structure directly: - -```ts -// Inside QueryBuilder -private toRawInput(): RawSelectInput { - const select: QueryPath[] = this._selections.map(sel => { - const steps = this.selectionToSteps(sel); - return steps.map(prop => ({ property: prop })); // QueryStep - }); - - return { - select, - shape: this._shape, - limit: this._limit, - offset: this._offset, - singleResult: false, - where: this._where.length ? this.buildWherePath() : undefined, - }; -} -``` - -This is the key insight: **we don't need to create new pipeline stages.** We produce the same `RawSelectInput` that proxy tracing produces, but we build it from explicit property shape references instead of proxy interception. - ---- - -## Open Questions - -1. **Result typing:** Dynamic queries can't infer result types statically. Should we provide a generic `ResultRow` type, or allow users to pass a type parameter (`QueryBuilder.from(PersonShape)`)? - -2. **Mutation builders:** Should `QueryBuilder` also support `.create()`, `.update()`, `.delete()` methods? The mutation IR (`IRCreateMutation`, etc.) is simpler — it might be easier to just expose the existing `buildCanonicalCreateMutationIR()` etc. directly. - -3. **~~Validation~~ — RESOLVED (yes):** The builder validates property shapes against the root shape (and traversed valueShapes). Any invalid string/path throws an error since the base shape is known. Operator validation against `sh:datatype` too (boolean → only `=`/`!=`, numeric → all comparisons, etc.). - -4. **~~Where clause composition~~ — RESOLVED:** QueryBuilder supports two forms: - - **Proxy callback** (matches DSL): `.where(p => p.age.gt(18))` — same proxy as DSL, type-validated - - **String shorthand** (convenience): `.where('age', '>', 18)` — resolves PropertyShape, validates operator vs datatype - - Both produce the same `WhereCondition`. JSON serialization uses plain-object form: `{ path: 'age', op: '>', value: 18 }`. - - L module (006) works in callbacks for computed expressions: `.where(p => L.gt(L.times(p.age, 12), 216))` - -5. **Path reuse across queries:** If paths are first-class (Option E influence), they could be defined once in a CMS schema config and reused across list views, detail views, filters, etc. - -6. **Scoped filter merging strategy:** When two FieldSets have scoped filters on the same traversal and are merged, AND is the safe default. But should we support OR? What about conflicting filters (one says `isActive = true`, another says `isActive = false`)? Detect and warn? - -7. **QueryBuilder immutability:** If every `.where()` / `.select()` / `.setFields()` / `.addFields()` returns a new builder, do we shallow-clone or use structural sharing? For typical CMS queries (< 20 paths, < 5 where clauses) shallow clone is fine. But for NL chat where queries evolve over many turns, structural sharing could matter. - -8. **Shape adapter scope:** Should adapters map just property labels, or also handle value transforms (e.g. `age` → compute from `birthDate`)? Value transforms require post-processing results, which is a different layer. Probably keep adapters as pure structural mapping and handle value transforms separately. - -9. **~~FieldSet serialization format~~ — RESOLVED:** Serialize at the QueryBuilder/FieldSet level (not the IR level). The IR is an internal compilation target, not a storage format. - - **Shape/property identifiers use prefixed IRIs** (e.g. `"my:PersonShape"`, not `"http://data.my-app.com/shapes/Person"`). Prefixes are resolved through the existing prefix registry. Unprefixed strings resolve as property labels on the base shape — any invalid string/path throws an error since the base shape is known. - - **QueryBuilder.toJSON()** format: - ```json - { - "shape": "my:PersonShape", - "fields": [ - { "path": "name" }, - { "path": "friends.name" }, - { "path": "hobbies.label", "as": "hobby" } - ], - "where": [ - { "path": "address.city", "op": "=", "value": "Amsterdam" }, - { "path": "age", "op": ">=", "value": 18 } - ], - "orderBy": [{ "path": "name", "direction": "asc" }], - "limit": 20, - "offset": 0 - } - ``` - - **QueryBuilder.fromJSON(json, shapeRegistry)** resolves prefixed IRIs → NodeShape/PropertyShape references, throws on unknown shapes/properties. - - **FieldSet.toJSON() / FieldSet.fromJSON()** independently serializable with the same format (just `shape` + `fields`). - -10. **Immutability implementation for FieldSet:** FieldSet entries are an array of `FieldSetEntry`. Extend/omit/pick create new arrays. But the entries themselves reference PropertyShapes (which are mutable objects in the current codebase). Should FieldSet deep-freeze its entries? Or is it sufficient that the FieldSet *array* is new (so you can't accidentally mutate the list), while PropertyShape references are shared? Probably the latter — PropertyShapes are effectively singletons registered on NodeShapes. - -11. **Shared variable bindings** — moved to [008-shared-variable-bindings.md](./008-shared-variable-bindings.md). For 003, just reserve optional `bindingName` fields in v1 types (see "forward-compatibility" section above). - -12. **ShapeAdapter property format — string vs reference resolution:** When the adapter `properties` map uses strings, the string is resolved as a property label on the respective shape (`from` shape for keys, `to` shape for values). When the adapter uses `{id: someIRI}` references, those are used directly. But what about dotted paths like `'address.city'`? These imply chained resolution: first resolve `address` on the `from` shape, then `city` on `address`'s valueShape. The target side similarly resolves `'address.addressLocality'` step by step. This makes dotted path mapping work, but should the adapter also support structural differences where one shape has a flat property and the other has a nested path? (e.g. `'city'` → `'address.addressLocality'`). Probably yes, but that's a later extension. - ---- - -## Implementation Plan - -### Phase 1: Core primitives -- [ ] `PropertyPath` value object with `.prop()` chaining, comparison methods (`.equals()`, `.gt()`, etc.), `.as()`, `.matches()`, `.select()` for sub-selection -- [ ] `walkPropertyPath(shape, 'friends.name')` — string path → `PropertyPath` resolution using `NodeShape.getPropertyShape(label)` + `PropertyShape.valueShape` walking -- [ ] `ProxiedPathBuilder` — shared proxy between DSL and dynamic builder.

A new public API enables CMS-style runtime query building. - ---- - -## Architecture Decisions - -### 1. DSL and QueryBuilder are the same system - -The DSL is syntactic sugar. Both paths produce the same `RawSelectInput` and feed through the same IR pipeline: - -``` -Person.select(p => [p.name]) → QueryBuilder internally → toRawInput() → buildSelectQuery() → SPARQL -QueryBuilder.from(PersonShape).select(p => [p.name]) → same path -``` - -One shared `ProxiedPathBuilder` proxy implementation. No separate codepaths. - -### 2. Immutable builders, PromiseLike execution - -- Every `.where()`, `.select()`, `.setFields()`, `.addFields()`, `.limit()`, etc. returns a **new** QueryBuilder (shallow clone). -- `QueryBuilder implements PromiseLike` — `await` triggers execution. -- No more `nextTick`. No more mutable `PatchedQueryPromise`. -- `.exec()` available for explicit execution without `await`. - -### 3. Method naming - -| Operation | FieldSet | QueryBuilder | -|---|---|---| -| Initial selection | — | `.select(fields)` | -| Replace all | `.set(fields)` | `.setFields(fields)` | -| Add to existing | `.add(fields)` | `.addFields(fields)` | -| Remove | `.remove(fields)` | `.removeFields(fields)` | -| Keep only | `.pick(fields)` | — | -| Union | `FieldSet.merge([...])` | — | - -### 4. Targeting: `.for()` / `.forAll()` - -- `.for(id)` — single ID (implies singleResult) -- `.forAll(ids?)` — specific list or all instances (no args) -- **Update requires targeting** — `Person.update({...})` without `.for()`/`.forAll()` is a type error. -- **Delete takes id directly** — `Person.delete(id)`, `Person.deleteAll(ids?)`. -- All targeting methods accept `string | NodeReferenceValue` (i.e. an IRI string or `{id: string}`). Bulk variants (`.forAll()`, `.deleteAll()`) accept arrays of either form. This supports both raw IRIs and node references from query results. - -### 5. Mutation builders: same pattern as QueryBuilder - -The existing mutation classes (`CreateQueryFactory`, `UpdateQueryFactory`, `DeleteQueryFactory`) are mutable, imperative, and not composable. They get replaced with immutable builders that follow the same pattern as QueryBuilder: - -- `Person.create({name: 'Alice'})` → `CreateBuilder` → `await` / `.exec()` -- `Person.update({name: 'Alice'}).for(id)` → `UpdateBuilder` → `await` / `.exec()` -- `Person.delete(id)` → `DeleteBuilder` → `await` / `.exec()` -- `Person.deleteAll(ids?)` → `DeleteBuilder` → `await` / `.exec()` - -All builders are immutable (each method returns a new instance) and implement `PromiseLike` for `await`-based execution. - -**Create** doesn't need targeting (it creates a new node). **Update requires targeting** — `.for(id)` or `.forAll(ids)` must be called before execution, enforced at the type level. **Delete takes ids directly** at construction. - -The builders delegate to the existing `MutationQueryFactory.convertUpdateObject()` for input normalization, and produce the same `IRCreateMutation` / `IRUpdateMutation` / `IRDeleteMutation` that feeds into `irToAlgebra`. - -### 6. FieldSet as the composable primitive - -FieldSet is a named, immutable, serializable collection of property paths rooted at a shape. It supports: -- Construction: `FieldSet.for(shape, fields)`, `FieldSet.for(shape).select(fields)`, `FieldSet.all(shape)`, callback form with proxy -- Composition: `.add()`, `.remove()`, `.set()`, `.pick()`, `FieldSet.merge()` -- Scoped filters: conditions that attach to a specific traversal -- Serialization: `.toJSON()` / `FieldSet.fromJSON()` -- Nesting: `{ friends: personSummary }` and `{ hobbies: ['label', 'description'] }` - -### 7. Bridge to existing pipeline: `toRawInput()` - -QueryBuilder produces `RawSelectInput` — the same structure proxy tracing produces. No new pipeline stages needed. The existing `buildSelectQuery()` → IRDesugar → IRCanonicalize → IRLower → irToAlgebra chain is reused as-is. - ---- - -## Inter-Component Contracts - -### PropertyPath (value object) - -```ts -class PropertyPath { - readonly segments: PropertyShape[];

Contains `SelectQueryFactory`, `QueryShape`, `QueryShapeSet`, `QueryBuilderObject`, proxy handlers (lines ~1018, ~1286, ~1309). Refactor to delegate to QueryBuilder internally. `PatchedQueryPromise` replaced. Proxy creation extracted into shared `ProxiedPathBuilder`. -- `src/queries/QueryFactory.ts` (~5.5 KB) — Currently contains an empty `abstract class QueryFactory` (extended by `SelectQueryFactory` and `MutationQueryFactory` as a marker) plus mutation-related type utilities (`UpdatePartial`, `SetModification`, `NodeReferenceValue`, etc.) imported by ~10 files. The empty abstract class should be removed (QueryBuilder replaces it). The types stay; file may be renamed to `MutationTypes.ts` later. -- `src/queries/IRDesugar.ts` (~12 KB) — Owns `RawSelectInput` type definition (lines ~22-31). Type may need extension if QueryBuilder adds new fields. Also defines `DesugaredSelectQuery` and step types. -- `src/queries/IRPipeline.ts` (~1 KB) — Orchestrates desugar → canonicalize → lower. May need minor adjustments if `buildSelectQuery` input types change. -- `src/queries/MutationQuery.ts` — `MutationQueryFactory` input normalization logic (`convertUpdateObject`, `convertNodeReferences`, etc.) to be extracted/reused by new builders. The factory class itself is replaced. -- `src/queries/CreateQuery.ts` — `CreateQueryFactory` replaced by `CreateBuilder`. Input conversion logic reused. -- `src/queries/UpdateQuery.ts` — `UpdateQueryFactory` replaced by `UpdateBuilder`. Input conversion logic reused. -- `src/queries/DeleteQuery.ts` — `DeleteQueryFactory` replaced by `DeleteBuilder`. Input conversion logic reused. -- `src/shapes/Shape.ts` — Update `Shape.select()` (line ~125), `Shape.query()` (line ~95), `Shape.selectAll()` (line ~211) to return QueryBuilder. Update `Shape.create()`, `Shape.update()`, `Shape.delete()` to return mutation builders. Add `.for()`, `.forAll()`, `.deleteAll()` with consistent id types. -- `src/index.ts` — Export new public API (`QueryBuilder`, `FieldSet`, `PropertyPath`, `CreateBuilder`, `UpdateBuilder`, `DeleteBuilder`) alongside existing namespace. - -### Existing pipeline (no changes expected) -- `src/queries/IntermediateRepresentation.ts` (~6.7 KB) — IR types stay as-is (`IRSelectQuery`, `IRGraphPattern`, `IRExpression`, mutations) -- `src/queries/IRCanonicalize.ts` (~5 KB) — no changes (normalizes WHERE expressions) -- `src/queries/IRLower.ts` (~11 KB) — no changes (builds graph patterns and projections) -- `src/sparql/irToAlgebra.ts` (~37 KB) — no changes (IR → SPARQL algebra) -- `src/sparql/algebraToString.ts` (~12 KB) — no changes (algebra → SPARQL string) - -### Supporting files (reference, may need minor touches) -- `src/queries/IRProjection.ts` (~4.3 KB) — Result mapping and projection extraction -- `src/queries/IRAliasScope.ts` (~1.7 KB) — Alias scope management for IR variables -- `src/utils/ShapeClass.ts` (~10.6 KB) — Shape metadata and property shape utilities -- `src/queries/QueryContext.ts` (~1.3 KB) — Query execution context - -### Existing tests (must pass after refactor) -- `src/tests/ir-select-golden.test.ts` — Golden tests for full IR generation -- `src/tests/sparql-select-golden.test.ts` — Golden tests for SPARQL output -- `src/tests/query.types.test.ts` — Compile-time type inference tests -- `src/test-helpers/query-fixtures.ts` — Test shapes (Person, Dog, Pet) and query factory builders - ---- - -## Potential Pitfalls - -1. **SelectQueryFactory complexity** — It's ~2100 lines / 72 KB with 4 interrelated classes (`SelectQueryFactory`, `QueryShape`, `QueryShapeSet`, `QueryBuilderObject`) and complex proxy tracing with mutable state. Refactoring it to use QueryBuilder internally without breaking existing behavior is the highest-risk change. Strategy: keep old code paths working alongside new ones initially, validate with existing golden tests (`ir-select-golden.test.ts`, `sparql-select-golden.test.ts`), then swap. - -2. **ProxiedPathBuilder extraction** — The proxy is currently embedded in SelectQueryFactory. Extracting it into a shared module that both the DSL and QueryBuilder use requires understanding all proxy trap behaviors and edge cases (`.select()` for sub-selection, `.where()` for scoped filters, `.as()` for bindings, `.path()` escape hatch). - -3. **Scoped filter representation** — FieldSet entries can carry scoped filters. These must be correctly lowered into `IRTraversePattern.filter` fields. The existing proxy-based scoped `.where()` already does this — need to ensure the FieldSet path produces identical IR. - -4. **String path resolution** — `walkPropertyPath('friends.name')` must walk `NodeShape.getPropertyShape('friends')` → get valueShape → `getPropertyShape('name')`. Need to handle cases where property labels are ambiguous or the valueShape isn't a NodeShape. - ---- - -## Resolved design decisions - -1. **Scoped filter merging** — AND by default. OR support deferred until needed in practice. -2. **Immutability implementation** — Shallow clone. Structural sharing deferred unless benchmarks show need. -3. **Desugar pass** — Phase 18 implemented direct FieldSet → desugar conversion, eliminating the SelectPath roundtrip. - -## Future work (noted, not in scope) - -- **Raw IR helpers** — `ir.select()`, `ir.shapeScan()`, `ir.traverse()` etc. for power-user direct IR construction. -- **Result typing** — Dynamic queries use generic `ResultRow` type for now. Potential future addition: `QueryBuilder.from(shape)` type parameter for static result typing. - ---- - -## Implementation Phases - -Top-down approach: tackle the riskiest refactor first (ProxiedPathBuilder extraction from the 72KB SelectQuery.ts), then build new APIs on the clean foundation. Existing golden tests (IR + SPARQL) act as the safety net throughout. - -### Global test invariants - -1. **All existing tests must pass after every phase.** The 477+ currently passing tests (18 suites) are the regression safety net. This includes golden IR tests, golden SPARQL tests, type inference tests, mutation parity tests, and algebra tests. No existing test may be deleted or weakened — only extended. -2. **Full test coverage for all new code.** Every new public class and function gets dedicated tests covering: construction, core API behavior, immutability guarantees, edge cases (empty inputs, invalid inputs, missing values), and IR equivalence against the existing DSL where applicable. -3. **Fuseki integration tests** are environment-dependent (skipped when Fuseki is unavailable). They must not be broken but are not required to run in CI. The SPARQL pipeline (irToAlgebra, algebraToString) is untouched, so these tests remain valid. -4. **Type-checking** via `npx tsc --noEmit` must pass with zero errors after every phase. - -### Dependency graph - -``` -Phase 1 (done) - ↓ -Phase 2 (done) - ↓ -Phase 3a (done) ←→ Phase 3b (done) [parallel after Phase 2] - ↓ ↓ -Phase 4 (done) [after 3a and 3b] - ↓ -Phase 5 (done) [after 4.4a and 3a — preloadFor + component integration] - ↓ -Phase 6 (done) [forAll multi-ID — independent, small, quick win] - ↓ -Phase 7 (done) [unified callback tracing — THE foundational refactor] - 7a: Extend FieldSetEntry data model (done) - ↓ - 7b: FieldSet.for() accepts ShapeClass + NodeShape overloads (done) - ↓ - 7c: Replace traceFieldsFromCallback with ProxiedPathBuilder (done) - ↓ - 7d: toJSON for callback-based selections + orderDirection fix (done) - ↓ - 7e: Typed FieldSet — carry callback return type (done) - ↓ -Phase 8 (done) [QueryBuilder direct IR — bypass SelectQueryFactory] - ↓ -Phase 9 (done) [sub-queries through FieldSet — DSL proxy produces FieldSets] - ↓ -Phase 10 (done) [remove SelectQueryFactory] - ↓ -Phase 11 (mostly done) [hardening — API cleanup, reviewed item by item] - ↓ -Phase 12 (done) [typed FieldSet — carry response type through sub-selects] - ↓ -Phase 13–15 (done) [dead code removal, type safety quick wins, QueryPrimitive consolidation] - ↓ -Phase 16 (deferred) [CreateQResult simplification — moved to separate plan] - ↓ -Phase 17 (done) [getQueryPaths monkey-patch cleanup] - ↓ -Phase 18 (done) [remove old SelectPath IR — direct FieldSet → desugar] - ↓ -Phase 19 (done) [ShapeConstructor — eliminate ShapeType, reduce as any casts] -``` - ---- - -### Phase 1 — ProxiedPathBuilder extraction + DSL rewire ✅ - -**Status: Complete.** - -Extracted `createProxiedPathBuilder()` from `SelectQueryFactory.getQueryShape()` into `src/queries/ProxiedPathBuilder.ts`.

The existing DSL uses complex conditional types (`QueryResponseToResultType`, `GetQueryResponseType`) that `QueryBuilder.then()` currently erases to `any`. This is a type-system concern that should be addressed alongside FieldSet and serialization in Phase 4. - -#### Tasks - -**2.1 — Add `walkPropertyPath` to PropertyPath.ts** -- Implement `walkPropertyPath(shape: NodeShape, path: string): PropertyPath` -- Resolve dot-separated labels: `'friends.name'` → walk `NodeShape.getPropertyShapes(true)` by label → follow `PropertyShape.valueShape` → `getShapeClass(valueShape).shape.getPropertyShapes(true)` → match next label -- Throw on invalid segments, missing valueShape, or non-NodeShape intermediates - -**2.2 — Create `QueryBuilder.ts`** -- Immutable class: every method (`.select()`, `.where()`, `.limit()`, `.offset()`, `.orderBy()`, `.for()`, `.forAll()`) returns a new shallow-cloned instance -- `static from(shape: NodeShape | ShapeType | string): QueryBuilder` — accepts NodeShape, shape class, or prefixed IRI string (resolved via `getShapeClass()`) -- `.select(fn)` — accepts callback `(p) => [...]` using `createProxiedPathBuilder()`, stores trace response -- `.select(fields)` — accepts `string[]` (resolved via `walkPropertyPath`) -- `.where(fn)` — accepts callback producing `Evaluation` (reuses existing `processWhereClause` / `LinkedWhereQuery`) -- `.for(id)` — sets subject + singleResult, accepts `string | NodeReferenceValue` -- `.forAll(ids?)` — sets subject for multiple or all, accepts `(string | NodeReferenceValue)[]` -- `.orderBy(fn, direction?)` — stores sort trace -- `.limit(n)`, `.offset(n)` — store pagination -- `.build(): IRSelectQuery` — calls `toRawInput()` → `buildSelectQuery()` -- `.exec(): Promise` — calls `getQueryDispatch().selectQuery(this.build())` -- `implements PromiseLike` — `.then()` delegates to `.exec()` -- Private `toRawInput(): RawSelectInput` — converts internal state to the same `RawSelectInput` that `SelectQueryFactory.toRawInput()` produces (same shape: `{ select, subject, limit, offset, shape, sortBy, singleResult, where }`) - -**2.3 — Rewire `Shape.select()`, `.selectAll()`, `.query()` in Shape.ts** -- `Shape.select(fn)` and `Shape.select(subject, fn)` return `QueryBuilder` instead of patched Promise -- `Shape.selectAll()` returns `QueryBuilder` using `FieldSet.all()` (or interim: build labels from `getUniquePropertyShapes`) -- `Shape.query(fn)` returns `QueryBuilder` (template, not executed) -- Remove `nextTick` import and the `new Promise` + `nextTick` wrapping in `Shape.select()` -- Remove `PatchedQueryPromise` usage — QueryBuilder's immutable `.where()`, `.limit()`, `.sortBy()`, `.one()` replace it -- Keep backward compatibility: chaining `.where().limit().sortBy()` on the result of `Shape.select()` must still work (QueryBuilder supports all these) - -**2.4 — Deprecate `SelectQueryFactory` public surface** -- `SelectQueryFactory` stays as an internal class (still used by `QueryShape.select()`, `QueryShapeSet.select()` for sub-queries) -- Remove `patchResultPromise()` method -- Remove `onQueriesReady` / DOMContentLoaded logic (was for browser bundle lazy init — QueryBuilder's PromiseLike model doesn't need it) -- Mark `SelectQueryFactory` as `@internal` — not part of public API -

See task 4.4 below for full breakdown. - -Add `toJSON()` / `fromJSON()` to QueryBuilder and FieldSet. Final integration: verify all public API exports, remove dead code. - -**Depends on:** Phase 3a (FieldSet) and Phase 3b (mutation builders) - -#### Tasks - -**4.1 — FieldSet serialization** -- `.toJSON(): FieldSetJSON` — produces `{ shape: string, fields: Array<{ path: string, as?: string }> }` where `shape` is the NodeShape id and `path` is dot-separated labels -- `static fromJSON(json, shapeRegistry?): FieldSet` — resolves shape id via `getShapeClass()`, resolves field paths via `walkPropertyPath()` - -**4.2 — QueryBuilder serialization** -- `.toJSON(): QueryBuilderJSON` — produces the JSON format specified in the plan contracts section -- `static fromJSON(json): QueryBuilder` — reconstructs builder from JSON, resolves shape and paths - -**4.3 — Update `src/index.ts` with full public API** -- Export `QueryBuilder`, `FieldSet`, `PropertyPath`, `walkPropertyPath` -- Export `CreateBuilder`, `UpdateBuilder`, `DeleteBuilder` -- Export `WhereCondition`, `WhereOperator` -- Remove `nextTick` re-export (no longer needed) -- Keep `SelectQueryFactory` export for backward compatibility but mark deprecated - -**4.4 — Builder type threading + DSL rewire + dead code cleanup** - -This is a multi-step sub-phase that threads result types through builder generics, rewires `Shape.*()` to return builders, and removes dead code. See detailed breakdown below. - -##### Phase 4.4a — Thread result types through QueryBuilder - -**Goal:** `await QueryBuilder.from(Person).select(p => p.name)` resolves to `QueryResponseToResultType[]` instead of `any`. - -**Proven viable:** A type probe (`src/tests/type-probe-4.4a.ts`) confirms that `QueryResponseToResultType` resolves correctly when used as a computed generic parameter in a class, including through `PromiseLike`/`Awaited<>`. All 4 probe scenarios pass: standalone type computation, SingleResult unwrap, class generic propagation, and full PromiseLike chain with `Awaited<>`. - -**Type inference scope:** Result type inference only works when `QueryBuilder.from(ShapeClass)` receives a TypeScript class. When using a string IRI (`QueryBuilder.from('my:PersonShape')`), `S` defaults to `Shape` and result types degrade to `any`. This is by design — the string/NodeShape path is for runtime/CMS use where types aren't known at compile time. The `` generic is required for type inference. - -**File:** `src/queries/QueryBuilder.ts` - -**Incremental implementation steps:** - -Each step is independently verifiable with `npx tsc --noEmit` and `npm test`. - -**Step 1 — Add `Result` generic parameter (pure additive, breaks nothing):** -```ts -// Before -export class QueryBuilder - implements PromiseLike, Promise - -// After — Result defaults to any, so all existing code compiles unchanged -export class QueryBuilder - implements PromiseLike, Promise -``` -Update `QueryBuilderInit` to carry `Result` if needed, or just propagate via generics. -**Tests:** No new type tests (Result = any). Validation: `npx tsc --noEmit` + `npm test` — all existing tests pass unchanged. - -**Step 2 — Wire `then()`, `catch()`, `finally()`, `exec()` to use `Result`:** -```ts -exec(): Promise { - return getQueryDispatch().selectQuery(this.build()) as Promise; -} -then( - onfulfilled?: ((value: Result) => TResult1 | PromiseLike) | null, - onrejected?: ((reason: any) => TResult2 | PromiseLike) | null, -): Promise { ... } -catch(...): Promise { ... } -finally(...): Promise { ... } -``` -Since `Result` still defaults to `any`, this is a no-op change at runtime and compile time. -**Tests:** No new type tests (Result = any). Validation: `npx tsc --noEmit` + `npm test`. - -**Step 3 — Wire `select()` to compute `Result` via `QueryResponseToResultType`:** -This is the key step. Import `QueryResponseToResultType` and update the callback overload: -```ts -import {QueryResponseToResultType} from './SelectQuery.js'; - -select(fn: QueryBuildFn): QueryBuilder[]>; -select(labels: string[]): QueryBuilder; -select(fieldSet: FieldSet): QueryBuilder; -``` -**Tests — add to `query-builder.types.test.ts` (compile-only, `describe.skip`):** -```ts -test('select literal property', () => { - const promise = QueryBuilder.from(Person).select(p => p.name); - type Result = Awaited; - const first = (null as unknown as Result)[0]; - expectType(first.name); - expectType(first.id); -}); -test('select object property (set)', () => { - const promise = QueryBuilder.from(Person).select(p => p.friends); - type Result = Awaited; - expectType((null as unknown as Result)[0].friends[0].id); -}); -test('select multiple paths', () => { - const promise = QueryBuilder.from(Person).select(p => [p.name, p.friends, p.bestFriend.name]); - type Result = Awaited; - const first = (null as unknown as Result)[0]; - expectType(first.name); - expectType(first.friends[0].id); - expectType(first.bestFriend.name); -}); -test('select date type', () => { - const promise = QueryBuilder.from(Person).select(p => p.birthDate); - type Result = Awaited; - expectType((null as unknown as Result)[0].birthDate); -}); -test('select boolean type', () => { - const promise = QueryBuilder.from(Person).select(p => p.isRealPerson); - type Result = Awaited; - expectType((null as unknown as Result)[0].isRealPerson); -}); -test('sub-select plural custom object', () => { - const promise = QueryBuilder.from(Person).select(p => - p.friends.select(f => ({name: f.name, hobby: f.hobby})), - ); - type Result = Awaited; - expectType((null as unknown as Result)[0].friends[0].name); - expectType((null as unknown as Result)[0].friends[0].hobby); -}); -test('count', () => { - const promise = QueryBuilder.from(Person).select(p => p.friends.size());

- type Result = Awaited; - expectType(null as unknown as Result); -}); -``` -Validation: `npx tsc --noEmit` + `npm test`. - -**Step 4 — Update fluent methods to preserve `Result`:** -Change `where()`, `orderBy()`, `limit()`, `offset()`, `for()`, `sortBy()` return types from `QueryBuilder` to `QueryBuilder`: -```ts -where(fn: WhereClause): QueryBuilder { ... } -limit(n: number): QueryBuilder { ... } -// etc. -``` -Update `clone()` to propagate `Result`: -```ts -private clone(overrides: Partial> = {}): QueryBuilder { - return new QueryBuilder({...}); -} -``` -**Tests — add to `query-builder.types.test.ts`:** -```ts -test('select with chaining preserves types', () => { - const promise = QueryBuilder.from(Person) - .select(p => [p.name, p.friends]) - .where(p => p.name.equals('x')) - .limit(5); - type Result = Awaited; - const first = (null as unknown as Result)[0]; - expectType(first.name); - expectType(first.friends[0].id); -}); -test('select with .for() preserves types', () => { - const promise = QueryBuilder.from(Person) - .select(p => p.name) - .for({id: 'p1'});

- type Result = Awaited; - expectType((null as unknown as Result)[0].name); -}); -``` -Validation: `npx tsc --noEmit` + `npm test`. - -**Step 5 — Wire `one()` to unwrap array:** -```ts -one(): QueryBuilder { - return this.clone({limit: 1, singleResult: true}) as any; -} -``` -**Tests — add to `query-builder.types.test.ts`:** -```ts -test('select with .one() unwraps array', () => { - const promise = QueryBuilder.from(Person).select(p => p.name).one(); - type Result = Awaited; - const single = null as unknown as Result; - expectType(single.name); - expectType(single.id); -}); -test('.one() after chaining', () => { - const promise = QueryBuilder.from(Person) - .select(p => [p.name, p.friends]) - .where(p => p.name.equals('x')) - .one(); - type Result = Awaited; - const single = null as unknown as Result; - expectType(single.name); - expectType(single.friends[0].id); -}); -``` -Validation: `npx tsc --noEmit` + `npm test`. - -**Step 6 — Wire `selectAll()` result type:** -```ts -selectAll(): QueryBuilder, S>[]> { ... } -``` -This requires importing `SelectAllQueryResponse` from SelectQuery.ts. -**Tests — add to `query-builder.types.test.ts`:** -```ts -test('selectAll returns typed results', () => { - const promise = QueryBuilder.from(Person).selectAll(); - type Result = Awaited; - const first = (null as unknown as Result)[0]; - expectType(first.id); - expectType(first.name); -}); -``` -Validation: `npx tsc --noEmit` + `npm test`. - -**Validation (full, after all steps):** -- `npx tsc --noEmit` passes -- All existing `query-builder.test.ts` tests pass (IR equivalence unchanged) -- New `query-builder.types.test.ts` (compile-only, `describe.skip`) mirroring key patterns from `query.types.test.ts`: - ```ts - test('select literal property', () => { - const promise = QueryBuilder.from(Person).select(p => p.name);

- }); - ``` - -**Risk (largely mitigated):** Type probe confirms `QueryResponseToResultType` resolves correctly through class generics and `Awaited`. The incremental 6-step approach means any step that fails can be diagnosed in isolation without rolling back prior steps. Each step is a self-contained commit. - ---- - -##### Phase 4.4b — Rewire Shape.select() / Shape.selectAll() to return QueryBuilder - -**Goal:** `Person.select(p => p.name)` returns `QueryBuilder` instead of `PatchedQueryPromise`. Chaining (`.where()`, `.limit()`, `.one()`, `.sortBy()`) works because QueryBuilder already has these methods. - -**File:** `src/shapes/Shape.ts` - -**Changes:** - -1. Add imports: -```ts -import {QueryBuilder} from '../queries/QueryBuilder.js'; -``` - -2. Replace `Shape.select()` implementation — remove `nextTick`, `SelectQueryFactory`, `patchResultPromise`: -```ts -static select< - ShapeType extends Shape, - S = unknown, - ResultType = QueryResponseToResultType[], ->( - this: {new (...args: any[]): ShapeType}, - selectFn: QueryBuildFn, -): QueryBuilder; -// ... keep subject overloads ... -static select(this, targetOrSelectFn?, selectFn?) { - let _selectFn, subject; - if (selectFn) { _selectFn = selectFn; subject = targetOrSelectFn; } - else { _selectFn = targetOrSelectFn; } - - let builder = QueryBuilder.from(this as any).select(_selectFn); - if (subject) builder = builder.for(subject); - return builder; -} -``` - -3. Replace `Shape.selectAll()` similarly: -```ts -static selectAll( - this: {new (...args: any[]): ShapeType}, -): QueryBuilder; -// ... subject overload ... -static selectAll(this, subject?) { - let builder = QueryBuilder.from(this as any).selectAll(); - if (subject) builder = builder.for(subject); - return builder; -} -``` - -4. Remove unused imports: `nextTick`, `PatchedQueryPromise`, `GetQueryResponseType`, `SelectAllQueryResponse`. Keep `SelectQueryFactory` import only if `Shape.query()` still uses it. - -**Breaking change analysis:** -- Return type changes from `Promise & PatchedQueryPromise` to `QueryBuilder`. -- Both are `PromiseLike`, so `await Person.select(...)` still works. -- `.where()`, `.limit()`, `.one()` still exist on QueryBuilder. -- `.sortBy()` exists on QueryBuilder (added as alias for `orderBy`). -- Downstream code that explicitly typed the return as `PatchedQueryPromise` will break — but `PatchedQueryPromise` is not re-exported in `index.ts`, so it's internal only. - -**Validation:** -- All `query-builder.test.ts` IR equivalence tests pass (DSL path now IS builder path, IR should be identical by construction) -- `npx tsc --noEmit` passes -- `npm test` — all tests pass -- Verify `.where().limit().sortBy()` chaining works on `Person.select(...)` result - ---- - -##### Phase 4.4c — Rewire Shape.create() / Shape.update() / Shape.delete() to return builders - -**Goal:** `Person.create(data)` returns `CreateBuilder`, `Person.update(id, data)` returns `UpdateBuilder`, `Person.delete(id)` returns `DeleteBuilder`. - -**File:** `src/shapes/Shape.ts` - -**Changes:** - -1. Add imports: -```ts -import {CreateBuilder} from '../queries/CreateBuilder.js'; -import {UpdateBuilder} from '../queries/UpdateBuilder.js'; -import {DeleteBuilder} from '../queries/DeleteBuilder.js'; -``` - -2. Replace `Shape.create()`: -```ts -static create>( - this: {new (...args: any[]): ShapeType}, - updateObjectOrFn?: U, -): CreateBuilder { - let builder = CreateBuilder.from(this as any); - if (updateObjectOrFn) builder = builder.set(updateObjectOrFn); - return builder; -} -``` - -3. Replace `Shape.update()`: -```ts -static update>( - this: {new (...args: any[]): ShapeType}, - id: string | NodeReferenceValue | QShape, - updateObjectOrFn?: U, -): UpdateBuilder { - const idValue = typeof id === 'string' ? id : (id as any).id; - let builder = UpdateBuilder.from(this as any).for(idValue); - if (updateObjectOrFn) builder = builder.set(updateObjectOrFn); - return builder; -} -``` - -4. Replace `Shape.delete()`: -```ts -static delete( - this: {new (...args: any[]): ShapeType}, - id: NodeId | NodeId[] | NodeReferenceValue[], -): DeleteBuilder { - return DeleteBuilder.from(this as any, id as any); -} -``` - -5. Remove imports: `CreateQueryFactory`, `UpdateQueryFactory`, `DeleteQueryFactory` - -**Breaking change analysis:** -- Return type changes from `Promise` to builder (which implements `PromiseLike`). -- `await Person.create(...)` still works identically. -- Code that chains `.then()` directly on the result still works (builders have `.then()`). -- Only breaks if someone does `instanceof Promise` checks on the result. - -**Validation:** -- `mutation-builder.test.ts` passes -- `npx tsc --noEmit` passes -- `npm test` — all tests pass - ---- - -##### Phase 4.4d — Thread result types through mutation builders - -**Goal:** `await CreateBuilder.from(Person).set(data)` resolves to `CreateResponse` instead of `any`. - -**Sub-steps:** - -**Step 4.4d.1 — CreateBuilder:** -- Add `U extends UpdatePartial = UpdatePartial` generic to class -- Wire `set()` to return `CreateBuilder` -- Wire `exec/then/catch/finally` to use `CreateResponse` instead of `any` -- Update `implements` clause to `PromiseLike>` -- Validation: `npx jest --testPathPattern='mutation-builder' --no-coverage` passes - -**Step 4.4d.2 — UpdateBuilder:** -- Add `U extends UpdatePartial = UpdatePartial` generic to class -- Wire `set()` to return `UpdateBuilder` -- Wire `exec/then/catch/finally` to use `AddId` instead of `any` -- `for()` preserves `U` generic: returns `UpdateBuilder` -- Update `implements` clause to `PromiseLike>` -- Validation: `npx jest --testPathPattern='mutation-builder' --no-coverage` passes - -**Step 4.4d.3 — Verify DeleteBuilder (no changes needed):** -- DeleteBuilder already uses `DeleteResponse` throughout — just confirm. -- Validation: full `npm test` passes - -Note: `DeleteBuilder` already has proper `DeleteResponse` typing — no changes needed. - -**Validation:** -- `mutation-builder.test.ts` passes -- `npx tsc --noEmit` passes - ---- - -##### Phase 4.4e — Dead code removal - -**Goal:** Remove all legacy code no longer reachable after 4.4b and 4.4c. - -**Changes by file:** - -1. **`src/queries/SelectQuery.ts`:** - - Remove `PatchedQueryPromise` type (lines 277-287) - - Remove `patchResultPromise()` method from `SelectQueryFactory` (lines 1863-1892) - -2. **`src/shapes/Shape.ts`:** - - Remove `import nextTick from 'next-tick'` - - Remove unused imports: `PatchedQueryPromise`, `GetQueryResponseType`, `SelectAllQueryResponse` - - Remove unused imports: `CreateQueryFactory`, `UpdateQueryFactory`, `DeleteQueryFactory` - - **Remove `Shape.query()` method** (lines 95-117) — this returned `SelectQueryFactory` directly as a "template" pattern. With QueryBuilder available, this method is no longer needed. Note: this is a **breaking change** for any code using `Shape.query()`. Document in changelog. - - Remove `SelectQueryFactory` import from Shape.ts entirely (no longer used after `query()` removal) - -3. **`src/index.ts`:** - - Remove `import nextTick from 'next-tick'` (line 47) - - Remove `export {nextTick}` (line 48) - -4. **`package.json`:** - - Remove `next-tick` from dependencies if no other file imports it - -**NOT removed (still used internally):** -- `SelectQueryFactory` class — still used by `QueryBuilder.buildFactory()` for IR generation -- `QueryResponseToResultType`, `GetQueryResponseType` — still used for type inference -- `MutationQueryFactory` — still used by mutation builders for `convertUpdateObject()` - -**Validation:** -- `npx tsc --noEmit` passes -- `npm test` — all tests pass -- `grep -r 'next-tick' src/` returns no hits (only in node_modules) -- `grep -r 'PatchedQueryPromise' src/` returns no hits -- `grep -r 'patchResultPromise' src/` returns no hits - ---- - -##### Phase 4.4f — Final validation - -- Run full test suite: `npm test` -- Run type check: `npx tsc --noEmit` -- Run build: `npm run build` (if available) -- Verify no `any` leaks in builder `.then()` signatures by inspecting the `.d.ts` output or running a type-level test -- Verify `nextTick` is not imported anywhere in src/ - ---- - -##### Phase 4.4 type invariant - -**Result types must stay identical.** The resolved `Awaited` types that consumers see from `Person.select(...)`, `Person.create(...)`, `Person.update(...)`, `Person.delete(...)` must not change. The existing `query.types.test.ts` (584 lines, 50+ compile-time type assertions) is the source of truth. All tests in that file must continue to compile without modification. If a test needs to change, that indicates a type regression — escalate before proceeding. - -Internal type plumbing (how `QueryResponseToResultType` flows through generics) is free to be restructured. Only the external-facing resolved types are contractual. - -A new `query-builder.types.test.ts` must be added mirroring key patterns from `query.types.test.ts` but using `QueryBuilder.from(...)` instead of the DSL. This proves both paths resolve to the same types. - -##### Phase 4.4 dependency graph - -``` -4.4a (type threading QueryBuilder) 4.4d (type threading mutation builders) - │ │ - ▼ ▼ -4.4b (rewire Shape.select/selectAll) 4.4c (rewire Shape.create/update/delete) - │ │ - └──────────────┬─────────────────────────┘ - ▼ - 4.4e (dead code removal) - │ - ▼ - 4.4f (final validation) -``` - -4.4a and 4.4d are independent and can be done in parallel. -4.4b depends on 4.4a. 4.4c depends on 4.4d. -4.4e depends on both 4.4b and 4.4c. -4.4f is the final gate. - -**4.5 — Integration verification** -- Run all existing golden tests (select + mutation) to confirm no regressions -- Verify `QueryBuilder` and old DSL produce identical IR for every fixture in `query-fixtures.ts` -- Verify mutation builders produce identical IR for every mutation fixture - -#### Validation — `src/tests/serialization.test.ts` - -**FieldSet round-trip tests:** -- `FieldSet.toJSON — simple fields`: `FieldSet.for(Person.shape, ['name', 'hobby']).toJSON()` — assert shape is Person's id, fields array has 2 entries with `path: 'name'` and `path: 'hobby'` -- `FieldSet.fromJSON — round-trip`: `FieldSet.fromJSON(fieldSet.toJSON())` — assert `.labels()` equals original `.labels()` -- `FieldSet.toJSON — nested`: `FieldSet.for(Person.shape, ['friends.name']).toJSON()` — assert field path is `'friends.name'` - -**QueryBuilder round-trip tests:** -- `QueryBuilder.toJSON — select + where + limit`: build a query, serialize, assert JSON has expected shape/fields/where/limit -- `QueryBuilder.fromJSON — round-trip IR equivalence`: serialize a QueryBuilder, deserialize, build IR from both, assert identical IR -- `QueryBuilder.toJSON — orderBy`: assert orderBy appears in JSON with correct path and direction - -**Integration tests:** -- `full pipeline — QueryBuilder from JSON produces valid SPARQL`: deserialize a QueryBuilder from JSON, build IR, convert to SPARQL algebra, convert to SPARQL string, assert string contains expected clauses - -**Validation commands:** -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass -- `npm run build` (if available) — clean build with no errors - ---- - -### Phase 5 — preloadFor + Component Query Integration ✅ - -**Status: Complete.** - -Integrate `preloadFor` with the new QueryBuilder/FieldSet system. Ensure `linkedComponent` (in `@_linked/react`) continues to work by accepting QueryBuilder-based component definitions alongside the legacy SelectQueryFactory pattern. - -**Depends on:** Phase 4.4a (QueryBuilder with result types), Phase 3a (FieldSet) - -#### Background - -The current `preloadFor` system works like this: - -1. `linkedComponent(query, ReactComponent)` creates a new React component with a `.query` property (a `SelectQueryFactory`) -2. The component satisfies `QueryComponentLike = { query: SelectQueryFactory | Record }` -3. In a parent query: `Person.select(p => p.bestFriend.preloadFor(ChildComponent))` creates a `BoundComponent` -4. `BoundComponent.getPropertyPath()` extracts the child's `SelectQueryFactory`, calls `getQueryPaths()`, and merges the result paths into the parent query path -5. The IR pipeline wraps the component's selections in an `OPTIONAL` block (so preloaded fields don't filter parent results) - -The current system is tightly coupled to `SelectQueryFactory`. This phase extends it to work with `QueryBuilder` and `FieldSet`. - -#### Architecture Decisions - -**1. `QueryComponentLike` accepts QueryBuilder and FieldSet** - -```ts -export type QueryComponentLike = { - query: - | SelectQueryFactory - | QueryBuilder - | FieldSet - | Record | QueryBuilder>; -}; -``` - -This is backward-compatible — existing components with `{query: SelectQueryFactory}` still work. - -**2. `linkedComponent` exposes both `.query` and `.fields`** - -The `@_linked/react` `linkedComponent` wrapper should expose: -- `.query` — a `QueryBuilder` (replaces the old `SelectQueryFactory` template) -- `.fields` — a `FieldSet` derived from the query's selection - -This is a contract that `@_linked/react` implements. Core defines the interface. - -**3. `Shape.query()` is removed — use `QueryBuilder.from()` directly** - -`Shape.query()` was a convenience that returned a `SelectQueryFactory` as a "template". With QueryBuilder available, the equivalent is `QueryBuilder.from(Person).select(p => ({name: p.name}))`. `linkedComponent` in `@_linked/react` should accept a `QueryBuilder` directly instead of relying on `Shape.query()`. - -`Shape.query()` is removed in Phase 4.4e as originally planned. `@_linked/react` must update `linkedComponent` to accept `QueryBuilder` before that happens (see `@_linked/react` migration note below). - -**4. `preloadFor` on PropertyPath for QueryBuilder API** - -The proxy-based DSL (`p.bestFriend.preloadFor(comp)`) already works via `QueryBuilderObject.preloadFor()`. For the QueryBuilder/FieldSet API, preloading is expressed as a nested FieldSet input or a dedicated method: - -```ts -// Option A: FieldSet nesting with component -FieldSet.for(Person.shape, [ - 'name', - { bestFriend: PersonCardComponent.fields } -]) - -// Option B: QueryBuilder.preload() method -QueryBuilder.from(Person) - .select(p => [p.name]) - .preload('bestFriend', PersonCardComponent) - -// Option C: Both — FieldSet nesting for static, preload() for dynamic -``` - -Decision: Support **both Option A and B**. FieldSet nesting (`{ path: FieldSet }`) already works for sub-selections. Component preloading through QueryBuilder adds a `.preload()` convenience method. - -#### Tasks - -**5.1 — Extend `QueryComponentLike` type** - -**File:** `src/queries/SelectQuery.ts` - -Update the type to accept `QueryBuilder` and `FieldSet`: - -```ts -export type QueryComponentLike = { - query: - | SelectQueryFactory - | QueryBuilder - | FieldSet - | Record | QueryBuilder>; - fields?: FieldSet; // optional: component can also expose a FieldSet -}; -``` - -**5.2 — Update `BoundComponent.getParentQueryFactory()` to handle new types** - -**File:** `src/queries/SelectQuery.ts` - -Rename to `getComponentQueryPaths()` (more accurate since it now returns paths from multiple sources). Handle: -- `SelectQueryFactory` → call `getQueryPaths()` (existing) -- `QueryBuilder` → call `buildFactory().getQueryPaths()` or `toRawInput()` and extract select paths -- `FieldSet` → convert to `QueryPath[]` via the existing FieldSet→QueryPath bridge (from Phase 3a.3) - -```ts -getComponentQueryPaths(): SelectPath { - const query = this.originalValue.query; - - // If component exposes a FieldSet, prefer it - if (this.originalValue.fields instanceof FieldSet) { - return fieldSetToQueryPaths(this.originalValue.fields); - } - - if (query instanceof SelectQueryFactory) { - return query.getQueryPaths(); - } - if (query instanceof QueryBuilder) { - return query.buildFactory().getQueryPaths(); - } - if (query instanceof FieldSet) { - return fieldSetToQueryPaths(query); - } - // Record case - if (typeof query === 'object') { - // ... existing Record handling, extended for QueryBuilder values - } -} -``` - -**5.3 — Add `.preload()` method to QueryBuilder** - -**File:** `src/queries/QueryBuilder.ts` - -Add a method that creates a preload relationship: - -```ts -preload( - path: string, - component: QueryComponentLike, -): QueryBuilder { - // Resolve the path, create a BoundComponent-like structure - // that the FieldSet→QueryPath bridge can handle - // Store as additional preload entries in the builder state -} -``` - -This stores preload bindings that get merged when `toRawInput()` is called. - -**5.4 — FieldSet nesting with component FieldSets** - -**File:** `src/queries/FieldSet.ts` - -FieldSet nesting already supports `{ friends: ['name', 'hobby'] }` and `{ friends: childFieldSet }`. Verify and test that this works correctly for component preloading: - -```ts -const personCardFields = FieldSet.for(Person.shape, ['name', 'hobby']); -const parentFields = FieldSet.for(Person.shape, [ - 'name', - { bestFriend: personCardFields } -]); -``` - -The existing `resolveInputs()` handles `Record` — this just needs validation that the resulting QueryPaths produce the correct OPTIONAL-wrapped SPARQL when going through the IR pipeline. - -**5.5 — Define `ComponentInterface` for `@_linked/react` contract** - -**File:** `src/queries/SelectQuery.ts` (or new file `src/queries/ComponentInterface.ts`) - -Define the interface that React components (from `@_linked/react`) must satisfy: - -```ts -export interface LinkedComponentInterface { - /** The component's data query (QueryBuilder template, not executed) */ - query: QueryBuilder | SelectQueryFactory; - /** The component's field requirements as a FieldSet */ - fields?: FieldSet; -} -``` - -This is what `linkedComponent()` in `@_linked/react` should produce. Export from `src/index.ts`. - -**5.6 — Remove `Shape.query()` (confirm Phase 4.4e removal)** - -`Shape.query()` is removed as planned in Phase 4.4e. No changes needed here — just confirm the removal doesn't break preloadFor tests (the test fixtures in `query-fixtures.ts` should be updated to use `QueryBuilder.from(Person).select(...)` instead of `Person.query(...)`). - -#### `@_linked/react` Migration Note - -When `@_linked/core` completes Phase 5, `@_linked/react` must update its `linkedComponent` implementation: - -1. **Accept `QueryBuilder` instead of `SelectQueryFactory`:** - ```ts - // Before (current) - function linkedComponent( - query: SelectQueryFactory, - component: React.ComponentType, - ): LinkedComponent; - - // After - function linkedComponent( - query: QueryBuilder, - component: React.ComponentType, - ): LinkedComponent; - ``` - -2. **Expose `.fields` on the returned component:** - ```ts - const result = linkedComponent(query, Component); - // result.query = the QueryBuilder passed in - // result.fields = query.fields() ← derive FieldSet from the QueryBuilder - ``` - -3. **Satisfy `LinkedComponentInterface`** (exported from `@_linked/core`): - The returned component must implement: - ```ts - interface LinkedComponentInterface { - query: QueryBuilder; - fields?: FieldSet; - } - ``` - -4. **Update `linkedComponent` call sites** from `Person.query(...)` to `QueryBuilder.from(Person).select(...)`: - ```ts - // Before - const PersonCard = linkedComponent(Person.query(p => ({name: p.name})), CardComponent); - // After - const PersonCard = linkedComponent(QueryBuilder.from(Person).select(p => ({name: p.name})), CardComponent); - ``` - -5. **`linkedSetComponent`** follows the same pattern — accept `QueryBuilder` or `Record` instead of `SelectQueryFactory`. - -These changes are required before `Shape.query()` is removed in Phase 4.4e. - -#### Validation — `src/tests/preload-component.test.ts` - -**Backward compatibility tests:** -- `preloadFor with SelectQueryFactory` — existing `preloadBestFriend` fixture produces same IR as before -- `preloadFor SPARQL golden` — same SPARQL with OPTIONAL wrapper - -**New QueryBuilder-based tests:** -- `preloadFor with QueryBuilder` — `Person.select(p => p.bestFriend.preloadFor({query: QueryBuilder.from(Person).select(p => ({name: p.name}))}))` produces equivalent IR -- `preloadFor with FieldSet` — `Person.select(p => p.bestFriend.preloadFor({query: FieldSet.for(Person.shape, ['name'])}))` produces equivalent IR -- `FieldSet nesting as preload` — `FieldSet.for(Person.shape, [{ bestFriend: FieldSet.for(Person.shape, ['name']) }])` through QueryBuilder produces correct IR with OPTIONAL - -**QueryBuilder.preload() tests:** -- `QueryBuilder.preload()` — `QueryBuilder.from(Person).select(p => [p.name]).preload('bestFriend', {query: personCardQuery})` produces equivalent IR to DSL `preloadFor` - -**Validation commands:** -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass - ---- - -### Phase 6: `forAll(ids)` — multi-ID subject filtering ✅ - -**Status: Complete.** - -Implemented `_subjects` field on QueryBuilder, `forAll(ids)` normalizes and stores IDs, generates `VALUES` clause in SPARQL, with full serialization support. 6 new tests in query-builder.test.ts + 2 serialization tests. - -**Goal:** Make `Person.select(...).forAll([id1, id2])` actually filter by the given IDs instead of silently ignoring them. - -**Current problem (resolved):** Both branches of `forAll()` (with and without `ids`) do the exact same thing: `clone({subject: undefined, singleResult: false})`. The IDs parameter is discarded. - -**Approach: `VALUES` clause (Option A)** - -Use a `VALUES ?subject { }` binding, consistent with how `.for(id)` already works for single subjects. - -#### Implementation - -1. **Add `_subjects` field to `QueryBuilder`:** - - New `private readonly _subjects?: NodeReferenceValue[]` field alongside existing `_subject` - - Update `QueryBuilderInit` and `clone()` to carry `_subjects` - - `forAll(ids)` stores normalized IDs in `_subjects`, clears `_subject` - - `for(id)` clears `_subjects` (mutually exclusive) - -2. **Update `buildFactory()` to pass subjects array:** - - When `_subjects` is set, pass to `SelectQueryFactory` (new parameter or method) - - Factory generates `VALUES ?subject { ... }` in the SPARQL output - -3. **Update `SelectQueryFactory.toRawInput()`:** - - Accept plural `subjects` in the raw input - - Generate appropriate `VALUES` clause or `FILTER(?subject IN (...))` depending on what the IR pipeline supports - -4. **Serialization:** - - `toJSON()` — serialize `_subjects` as string array - - `fromJSON()` — restore `_subjects` and call `.forAll(ids)` - -#### Validation - -- Test: `Person.select(p => [p.name]).forAll([id1, id2])` produces IR with VALUES binding for both IDs -- Test: `.forAll()` without IDs still selects all (no subject filter) -- Test: `.for(id)` after `.forAll(ids)` clears the multi-subject (and vice versa) -- Test: serialization round-trip preserves subjects array -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass - ---- - -### Phase 7: Unified callback tracing — FieldSet as canonical query primitive ✅ - -**Status: Complete.** - -All sub-phases (7a–7e) implemented. FieldSetEntry extended with subSelect/aggregation/customKey. FieldSet.for() accepts ShapeClass. Callback tracing uses createProxiedPathBuilder. toJSON works for callback-based selections. FieldSet carries generic `` type parameters. - -**Goal:** Make FieldSet the single canonical declarative primitive that queries are built from. Unify FieldSet's callback tracing with the existing `QueryShape`/`ProxiedPathBuilder` proxy so nested paths, where clauses, and orderBy all work. Enable `toJSON()` for callback-based selections. Add type parameter `R` to FieldSet. - -**Current problem (resolved):** - -`FieldSet.traceFieldsFromCallback()` uses a **simple proxy** that only captures top-level string keys: -```ts -// Current: only captures 'friends', not 'friends.name' -const proxy = new Proxy({}, { - get(_target, key) { accessed.push(key); return key; } -}); -``` - -Meanwhile, `createProxiedPathBuilder()` → `QueryShape.create()` uses the **full QueryShape proxy** that: -- Resolves each key to its `PropertyShape` via `getPropertyShapeByLabel()` -- Returns nested `QueryBuilderObject` instances for traversal (`p.friends.name` works) -- Supports `.where()`, `.count()`, `.preloadFor()`, etc. -- Already handles both single-value (`QueryShape`) and set-value (`QueryShapeSet`) properties - -These should be the same code path. The DSL already solves nested path tracing — FieldSet just isn't using it. - -**Approach: Reuse `createProxiedPathBuilder` in FieldSet, extend FieldSetEntry data model, add typed generics.** - ---- - -#### Phase 7a: Extend FieldSetEntry data model - -**Goal:** Expand `FieldSetEntry` so it can carry everything that `QueryPath` / `PropertyQueryStep` currently carries. Pure data model change — no behavior changes yet. - -1. **Extend `FieldSetEntry` type:** - ```ts - type FieldSetEntry = { - path: PropertyPath; - alias?: string; - scopedFilter?: WhereCondition; // existing but unused — will be populated in 7c - subSelect?: FieldSet; // NEW: nested selections (p.friends.select(...)) - aggregation?: 'count'; // NEW: p.friends.size() - customKey?: string; // NEW: keyed results from custom objects - }; - ``` - -2. **Update FieldSet methods to preserve new fields:** - - `add()`, `remove()`, `pick()`, `merge()` — carry `subSelect`, `aggregation`, `customKey` through - - `toJSON()` / `fromJSON()` — serialize new fields where possible (sub-selects serialize recursively, aggregation as string) - - Path equality checks — entries with same path but different subSelect/aggregation are distinct - -3. **No behavior changes yet** — existing code continues to produce entries with only `path` and optional `alias`. New fields are optional and unused until 7b. - -##### Validation -- Existing FieldSet tests pass unchanged -- New test: FieldSetEntry with `subSelect` field preserved through `add()` / `pick()` / `merge()` -- New test: `toJSON()` / `fromJSON()` round-trip with `subSelect` and `aggregation` fields -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass - ---- - -#### Phase 7b: `FieldSet.for()` accepts ShapeClass + NodeShape overloads - -**Goal:** Allow `FieldSet.for()` to accept a Shape class (e.g. `Person`) in addition to `NodeShape` or string. This is prerequisite for using `createProxiedPathBuilder` which needs a Shape class. - -1. **Add ShapeClass overload to `FieldSet.for()`:** - ```ts - static for(shape: ShapeType, labels: string[]): FieldSet; - static for(shape: ShapeType, fn: (p: ProxiedShape) => any[]): FieldSet; - static for(shape: NodeShape | string, labels: string[]): FieldSet; - static for(shape: NodeShape | string, fn: (p: any) => any[]): FieldSet; - ``` - -2. **Resolve ShapeClass → NodeShape internally:** - - When given a ShapeClass, extract `shape.shape` (the NodeShape instance) - - Store the ShapeClass reference for later use in callback tracing (7c) - - `resolveShape()` updated to handle both input types - -3. **Same for `FieldSet.all()`:** - - Accept ShapeClass in addition to NodeShape/string - -4. **No callback behavior change yet** — callbacks still go through the simple proxy for now. ShapeClass is stored but the richer proxy isn't used until 7c. - -##### Validation -- Test: `FieldSet.for(Person, ['name'])` produces same FieldSet as `FieldSet.for(Person.shape, ['name'])` -- Test: `FieldSet.all(Person)` produces same FieldSet as `FieldSet.all(Person.shape)` -- Existing tests pass unchanged -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass - ---- - -#### Phase 7c: Replace traceFieldsFromCallback with ProxiedPathBuilder - -**Goal:** Replace FieldSet's simple string-capturing proxy with `createProxiedPathBuilder`. This enables nested paths, where conditions, sub-selects, and aggregations in FieldSet callbacks. - -**Core principle:** FieldSet is the canonical declarative primitive. The DSL's proxy tracing produces FieldSet entries, not a parallel QueryPath representation. - -1. **Replace `traceFieldsFromCallback` with `createProxiedPathBuilder`:** - - When given a ShapeClass, use `createProxiedPathBuilder(shape)` to get a full `QueryShape` proxy - - When given a NodeShape, reverse-lookup to ShapeClass via registry - - Pass proxy through callback: `fn(proxy)` returns `QueryBuilderObject[]` - - Convert each `QueryBuilderObject` to a `FieldSetEntry` (see step 2) - -2. **Add `QueryBuilderObject → FieldSetEntry` conversion utility:** - - Walk the `QueryBuilderObject` chain (each has `.property: PropertyShape` and `.subject: QueryBuilderObject`) - - Collect segments into a `PropertyPath` - - `.wherePath` → `scopedFilter` - - Sub-`SelectQueryFactory` result → `subSelect: FieldSet` (recursive conversion) - - `SetSize` instance → `aggregation: 'count'` - - This is the single bridge between the proxy world and the FieldSet world - -3. **Remove old `traceFieldsFromCallback`** — replaced entirely - -4. **This immediately enables:** - - Nested paths: `FieldSet.for(Person, p => [p.friends.name])` - - Where on paths: `FieldSet.for(Person, p => [p.friends.where(f => f.age.gt(18))])` - - Aggregations: `FieldSet.for(Person, p => [p.friends.size()])` - - Sub-selects: `FieldSet.for(Person, p => [p.friends.select(f => [f.name])])` - -##### Validation -- Test: `FieldSet.for(Person, p => [p.friends.name])` produces entry with 2-segment PropertyPath -- Test: `FieldSet.for(Person, p => [p.friends.where(f => f.age.gt(18))])` produces entry with `scopedFilter` populated -- Test: `FieldSet.for(Person, p => [p.friends.size()])` produces entry with `aggregation: 'count'` -- Test: `FieldSet.for(Person, p => [p.friends.select(f => [f.name])])` produces entry with `subSelect` FieldSet -- Test: existing flat callbacks `FieldSet.for(Person, p => [p.name])` still work -- IR equivalence: FieldSet-built nested query produces same IR as DSL equivalent -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass - ---- - -#### Phase 7d: `toJSON()` for callback-based selections - -**Goal:** Make `QueryBuilder.toJSON()` work when the selection was set via a callback (not just FieldSet or string[]). - -**Depends on:** Phase 7c (FieldSet callbacks now produce full entries via the real proxy) - -1. **Pre-evaluate callbacks in `fields()`:** - - When `_selectFn` is set but `_fieldSet` is not, run the callback through `createProxiedPathBuilder` to produce a `FieldSet` - - Cache the result (the callback is pure — same proxy always produces same paths) - - `toJSON()` then naturally works because `fields()` always returns a `FieldSet` - -2. **`fromJSON()` restores `orderDirection`:** - - Fix the existing bug: read `json.orderDirection` and store it - - Since the sort *key* callback isn't serializable, store direction separately — when a sort key is later re-applied, the direction is preserved - -3. **Where/orderBy callback serialization (exploration):** - - `where()` callbacks use the same `QueryShape` proxy — the result is a `WherePath` - - `orderBy()` callbacks produce a single `QueryBuilderObject` identifying the sort property - - Both could be pre-evaluated through the proxy and serialized as path expressions - - **Scope decision needed:** Is serializing where/orderBy required now, or can it wait? The `FieldSet.scopedFilter` field already exists for per-field where conditions — this could be the serialization target - -##### Validation -- Test: `QueryBuilder.from(Person).select(p => [p.name]).toJSON()` produces fields even with callback select -- Test: round-trip `toJSON()`/`fromJSON()` preserves callback-derived fields -- Test: `orderDirection` survives `fromJSON()` round-trip -- Test: nested callback selections serialize correctly (sub-selects, where, aggregation) -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass - ---- - -#### Phase 7e: Typed FieldSets — carry `R` through FieldSet - -**Goal:** When a FieldSet is built from a callback, capture the callback's return type as a generic parameter so that `QueryBuilder.select(fieldSet)` preserves type safety. - -**Depends on:** Phase 7c (FieldSet callbacks go through real proxy which produces typed results) - -1. **Add generic `R` parameter to FieldSet:** - ```ts - class FieldSet { - // When built from callback: R = callback return type - // When built from labels/string[]: R = any (no inference possible) - } - ``` - -2. **Wire callback type capture:** - ```ts - static for( - shape: ShapeType, - fn: (p: ProxiedShape) => R, - ): FieldSet; - ``` - -3. **Wire through QueryBuilder.select():** - ```ts - select(fieldSet: FieldSet): QueryBuilder[]>; - ``` - -4. **Composition preserves types where possible:** - - `.add()`, `.remove()`, `.pick()` on a typed FieldSet degrade `R` to `any` (composition changes the structure) - - `.merge()` degrades to `any` - - Only the original callback-constructed FieldSet carries the precise type - -##### Validation -- Test: `FieldSet.for(Person, p => [p.name])` → FieldSet carries type, `QueryBuilder.select(fieldSet)` resolves to typed result -- Test: `FieldSet.for(Person.shape, ['name'])` → FieldSet (no callback, no type) -- Type probe file: compile-time assertions for FieldSet → QueryBuilder result type flow -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass - ---- - -### Phase 8: QueryBuilder generates IR directly — bypass SelectQueryFactory ✅ - -**Status: Complete.** - -QueryBuilder.toRawInput() now constructs RawSelectInput directly from FieldSet when selections are set via FieldSet, labels, or selectAll. Arbitrary callbacks still use the legacy path (via _buildFactory()) until Phase 9. - -**Files delivered:** -- `src/queries/SelectQuery.ts` — exported `fieldSetToSelectPath()` (enhanced: handles aggregation, scopedFilter, subSelect), `processWhereClause()`, `evaluateSortCallback()` -- `src/queries/QueryBuilder.ts` — new `_buildDirectRawInput()`, `buildFactory` renamed to `_buildFactory()` and marked deprecated -- `src/tests/query-builder.test.ts` — 8 new tests in "QueryBuilder — direct IR generation" block - -**Scope note:** Only FieldSet/label/selectAll selections use the direct path. Arbitrary callbacks (which may produce BoundComponent, Evaluation, or SelectQueryFactory results) fall back to the legacy _buildFactory() path. Phase 9 will handle sub-selects through FieldSet, enabling more callbacks to use the direct path. - -**Original plan below for reference:** - -**Goal:** Remove the `buildFactory()` bridge. QueryBuilder converts its internal state (FieldSet-based) directly to `RawSelectInput`, bypassing `SelectQueryFactory` entirely for top-level queries. - -**Depends on:** Phase 7 (FieldSet carries full query information including where/sub-select/aggregation) - -**Current state:** `QueryBuilder.buildFactory()` creates a fresh `SelectQueryFactory`, passes the callback + state, lets the factory run the proxy tracing + `getQueryPaths()`, then calls `toRawInput()`. This is the legacy bridge. - -**Target state:** QueryBuilder holds a `FieldSet` (from Phase 7, carrying where/sub-select/aggregation). It converts `FieldSet → RawSelectInput` directly: - -#### Implementation - -1. **Build `fieldSetToRawSelectInput()` conversion:** - - Walk `FieldSetEntry[]` and produce `QueryPath[]` (the format `RawSelectInput.select` expects) - - Each `PropertyPath` segment → `PropertyQueryStep { property, where? }` - - `entry.scopedFilter` → `PropertyQueryStep.where` - - `entry.subSelect` → nested `QueryPath[]` (recursive) - - `entry.aggregation === 'count'` → `SizeStep { count, label }` - - This replaces the `SelectQueryFactory.getQueryPaths()` call - -2. **Replace `buildFactory()` with direct `toRawInput()`:** - ```ts - private toRawInput(): RawSelectInput { - const fields = this.fields(); // FieldSet with full info - return { - select: fieldSetToSelectPath(fields), - where: this._whereFn ? evaluateWhere(this._whereFn, this._shape) : undefined, - sortBy: this._sortByFn ? evaluateSort(this._sortByFn, this._shape) : undefined, - subject: this._subject, - shape: this._shape, - limit: this._limit, - offset: this._offset, - singleResult: this._singleResult, - }; - } - ``` - -3. **Evaluate where/sort callbacks independently:** - - `evaluateWhere()`: run callback through `createProxiedPathBuilder`, extract `WherePath` - - `evaluateSort()`: run callback through proxy, extract sort path + direction - - These are one-shot evaluations (same as what SelectQueryFactory.init() does) - -4. **Keep `buildFactory()` as deprecated fallback** (removed in Phase 10) - -#### Validation - -- Test: Every IR equivalence test from Phase 2 still passes when going through the new direct path -- Test: Sub-selections via FieldSet produce identical IR to DSL sub-selects -- Test: Where conditions on paths produce identical IR -- Test: Aggregations produce identical IR -- Golden SPARQL tests pass unchanged -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass - ---- - -### Phase 9: Sub-queries through FieldSet — remove SelectQueryFactory from DSL path - -**Goal:** When the DSL does `p.friends.select(f => [f.name, f.hobby])`, the sub-selection is represented as a nested `FieldSet` instead of a nested `SelectQueryFactory`. This means `QueryShape.select()` and `QueryShapeSet.select()` produce FieldSets, not factories. - -**Depends on:** Phase 8 (QueryBuilder generates IR directly from FieldSet) - -**Current sub-query flow:** -``` -p.friends.select(fn) - → QueryShapeSet.select(fn) creates new SelectQueryFactory(valueShape, fn) - → Factory stored as response element - → getQueryPaths() recurses into factory.getQueryPaths() - → Produces nested QueryPath[] -``` - -**Target sub-query flow:** -``` -p.friends.select(fn) - → QueryShapeSet.select(fn) creates FieldSet.for(valueShape, fn) - → FieldSet stored in parent FieldSetEntry.subSelect - → fieldSetToSelectPath() recurses into sub-FieldSet - → Produces nested QueryPath[] (same output) -``` - -#### Implementation - -1. **Update `QueryShapeSet.select()` to produce FieldSet:** - - Instead of `new SelectQueryFactory(valueShape, fn)`, call `FieldSet.for(valueShape, fn)` - - Store result as `FieldSetEntry.subSelect` on the parent entry - - This requires the `QueryBuilderObject → FieldSetEntry` conversion from Phase 7 to handle recursion - -2. **Update `QueryShape.select()` similarly:** - - Single-value sub-selections also produce FieldSet - -3. **Update `BoundComponent.getComponentQueryPaths()`:** - - For preloadFor, convert component's query to FieldSet - - Merge component's FieldSet into parent's sub-selection at the preload path - -4. **Remove SelectQueryFactory creation from proxy handlers:** - - `QueryShapeSet.select()` no longer imports/creates SelectQueryFactory - - `QueryShape.select()` no longer imports/creates SelectQueryFactory - - SelectQueryFactory only used by legacy code paths - -#### Validation - -- Test: `Person.select(p => p.friends.select(f => [f.name]))` produces identical IR through FieldSet path -- Test: `Person.select(p => p.friends.select(f => ({name: f.name, hobby: f.hobby})))` handles custom objects -- Test: Nested sub-selects (3+ levels deep) produce correct IR -- Test: preloadFor through FieldSet produces same OPTIONAL-wrapped IR -- Golden IR + SPARQL tests pass unchanged -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass - ---- - -### Phase 10: Remove SelectQueryFactory ✅ - -**Status: COMPLETE** — All 7 sub-phases (10a–10g) implemented and committed. - -**Goal:** Delete `SelectQueryFactory` and all supporting code that is no longer reachable. - -**Depends on:** Phase 9 (all DSL paths use FieldSet, no code creates SelectQueryFactory) - -#### Implementation - -1. **Verify no remaining usages:** - - `grep -r 'SelectQueryFactory' src/` should only find the definition and type-only imports - - `grep -r 'buildFactory' src/` should find nothing (removed in Phase 8) - - Confirm `QueryBuilder.buildFactory()` deprecated path is removed - -2. **Remove from SelectQuery.ts:** - - Delete `SelectQueryFactory` class (~600 lines) - - Delete `patchResultPromise()` (already removed in 4.4e, confirm) - - Delete `PatchedQueryPromise` type (already removed in 4.4e, confirm) - - Keep: `QueryShape`, `QueryShapeSet`, `QueryBuilderObject` — still used by proxy tracing - - Keep: Type exports (`QueryResponseToResultType`, `SelectAllQueryResponse`, etc.) - - Keep: `QueryComponentLike`, `BoundComponent` if still needed - -3. **Remove from exports:** - - Remove `SelectQueryFactory` from `src/index.ts` - - Remove from `QueryFactory.ts` if referenced there - -4. **Clean up `QueryContext.ts`:** - - If `QueryContext` was only used by SelectQueryFactory, remove it - - Otherwise keep - -5. **Update remaining references:** - - `QueryComponentLike` type no longer needs `SelectQueryFactory` variant - - Any `instanceof SelectQueryFactory` checks → remove or replace - -#### Validation - -- `grep -r 'SelectQueryFactory' src/` returns 0 hits (excluding comments/changelog) -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass -- Golden IR + SPARQL tests pass unchanged -- Bundle size reduced (SelectQueryFactory was ~600 lines) - ---- - -### Phase 11: Hardening — API cleanup and robustness - -**Goal:** Address remaining review findings. Each item to be discussed with project owner before implementation. - -**Depends on:** Phases 6–10 complete - -**Candidate items (to be reviewed individually):** - -1. **`FieldSet.merge()` shape validation** — should it throw when merging FieldSets from different shapes, or silently take the first shape? - -2. **`CreateBuilder.build()` missing-data guard** — should it throw like UpdateBuilder does when no data is set, or is `{}` valid for creating an empty node? - -3. **`FieldSet.all()` depth parameter** — implement recursive depth enumeration, or remove the parameter? What does depth > 1 mean for circular shape references? - -4. **`FieldSet.select()` vs `FieldSet.set()` duplication** — remove one? Which name is canonical? - -5. **Dead import cleanup** — remove `FieldSetJSON` import from QueryBuilder.ts, `toNodeReference` import from UpdateBuilder.ts - -6. **`toJSON()` dead branch** — remove unreachable `else if (this._selectAllLabels)` in QueryBuilder.toJSON() - -7. **Reduce `as any` / `as unknown as` casts** — now that Phase 7 unifies the proxy code and Phase 9 removes the factory bridge, many of the 28 `as any` casts in the queries directory should be eliminable - -8. **Clone type preservation** — `clone()` currently returns `QueryBuilder` then casts back. With the architecture settled, can clone preserve all generic parameters properly? - -9. **`PropertyPath.segments` defensive copy** — constructor receives bare `PropertyShape[]` array, caller could mutate. Add `Object.freeze` or slice? - -10. **`FieldSet.traceFieldsFromCallback` removal** — after Phase 7 replaces it with `createProxiedPathBuilder`, delete the old simple proxy code - ---- - -## Scope boundaries - -**In scope (this plan):** -- PropertyPath (value object, segments, comparison helpers with `sh:datatype` validation) -- walkPropertyPath (string path → PropertyPath resolution) -- ProxiedPathBuilder extraction (shared proxy between DSL and dynamic builders, `.path()` escape hatch) -- FieldSet as canonical query primitive (construction, composition, scoped filters, sub-selections, aggregations, nesting, serialization) -- QueryBuilder (fluent chain, immutable, PromiseLike, direct IR generation, serialization) -- Mutation builders: CreateBuilder, UpdateBuilder, DeleteBuilder (immutable, PromiseLike, reuse existing IR pipeline) -- DSL alignment (Person.select/create/update/delete → returns builders, .for()/.forAll() pattern) -- Shape resolution by prefixed IRI string (for `.from('my:PersonShape')` and JSON deserialization) -- `Person.selectAll({ depth })` — FieldSet.all with depth exposed on DSL -- Tests verifying DSL and builders produce identical IR -- `forAll(ids)` — multi-ID subject filtering via VALUES clause (Phase 6) -- Unified callback tracing — FieldSet reuses ProxiedPathBuilder, carries where/sub-select/aggregation, typed `FieldSet` (Phase 7) -- Direct IR generation — QueryBuilder bypasses SelectQueryFactory, converts FieldSet → RawSelectInput (Phase 8) -- Sub-queries through FieldSet — DSL proxy produces nested FieldSets instead of nested SelectQueryFactory (Phase 9) -- SelectQueryFactory removal (Phase 10a–10g): Evaluation support in FieldSetEntry (10a), preload/BoundComponent support (10b), standalone where evaluation replacing LinkedWhereQuery (10c), lightweight sub-select wrapper replacing factory in proxy handlers (10d), remove _buildFactory() (10e), migrate type utilities (10f), delete SelectQueryFactory class (10g) -- Hardening — API cleanup, robustness, cast reduction (Phase 11, items reviewed individually) - -**Out of scope (separate plans, already have ideation docs):** -- `FieldSet.summary()` — CMS-layer concern, not core -- Shared variable bindings / `.as()` activation → 008 -- Shape remapping / ShapeAdapter → 009 -- Computed expressions / L module → 006 -- Raw IR helpers (Option A) → future -- CONSTRUCT / MINUS query types → 004, 007 - ---- - -## Task Breakdown (Phases 6–11) - -### Dependency Graph - -``` -Phase 6 [independent — can run in parallel with 7a/7b] -Phase 7a [independent — pure data model] - ↓ -Phase 7b [depends on 7a — uses new entry fields] - ↓ -Phase 7c [depends on 7b — uses ShapeClass overloads] - ↓ -Phase 7d ←→ Phase 7e [both depend on 7c, independent of each other — can run in parallel] - ↓ ↓ -Phase 8 [depends on 7c+7d+7e — needs FieldSet with full info + serialization + types] - ↓ -Phase 9 [depends on 8 — FieldSet replaces factory in DSL proxy] - ↓ -Phase 10a ←→ 10b ←→ 10c ←→ 10d [all depend on 9, independent of each other — can run in parallel] - ↓ ↓ ↓ ↓ -Phase 10e [depends on 10a+10b+10c+10d — remove _buildFactory()] - ↓ -Phase 10f [depends on 10e — migrate type utilities] - ↓ -Phase 10g [depends on 10f — delete SelectQueryFactory class] - ↓ -Phase 11 [depends on 10g — cleanup pass] -``` - -**Parallel opportunities:** -- Phase 6, 7a can run in parallel (no shared code) -- Phase 7d, 7e can run in parallel after 7c (7d = serialization, 7e = types — no overlap) -- Phase 10a, 10b, 10c, 10d can all run in parallel after Phase 9 (each removes one dependency cluster independently) - ---- - -### Phase 6: forAll(ids) — multi-ID subject filtering ✅ - -#### Tasks - -1.

Add overload signatures to `FieldSet.for()` accepting `ShapeType` (shape class like `Person`) -2. Update `resolveShape()` to handle ShapeClass input — extract `.shape` property to get NodeShape -3. Add same overload to `FieldSet.all()` — accept ShapeClass -4. Store ShapeClass reference on FieldSet instance (private `_shapeClass?: ShapeType`) for later use in 7c -5.

Add generic parameter `R` to FieldSet class: `class FieldSet` -2. Update `FieldSet.for()` overload for callback form to capture `R`: `static for(shape: ShapeType, fn: (p: ProxiedShape) => R): FieldSet` -3. String/label overloads return `FieldSet` (no type inference possible) -4. Wire through `QueryBuilder.select()`: `select(fieldSet: FieldSet): QueryBuilder` -5.

Instead of changing `QueryShapeSet.select()` (which would break the legacy path), we enhanced `FieldSet.convertTraceResult()` to extract sub-select FieldSets from the factory's `traceResponse`. Callbacks producing sub-selects now go through the direct FieldSet→RawSelectInput path via try/catch fallback. Callbacks with Evaluation or BoundComponent (preload) results still fall back to the legacy path. - -**Files delivered:** -- `src/queries/FieldSet.ts` — enhanced `convertTraceResult()` for SelectQueryFactory extraction, added `extractSubSelectEntries()`, `createInternal()`, duck-type detectors for Evaluation and BoundComponent -- `src/queries/SelectQuery.ts` — `fieldSetToSelectPath()` returns `SelectPath` (supports `CustomQueryObject` when all entries have `customKey`), refactored to use `entryToQueryPath()` helper -- `src/queries/QueryBuilder.ts` — `toRawInput()` uses try/catch for callback direct path, preload guard restored -- `src/tests/field-set.test.ts` — 4 new tests in "FieldSet — sub-select extraction" block - -**Original plan below for reference:** - -#### Tasks - -1.

Update `QueryShape.select()` — same change for single-value sub-selections -3. Update `BoundComponent.getComponentQueryPaths()` — convert component's query to FieldSet, merge into parent sub-selection -4.

Call `validation(proxy)` — the where callback — returns an Evaluation -4. Call `evaluation.getWherePath()` directly - -**Key pitfall:** The `shape` parameter to `processWhereClause()` can be a `ShapeType` (class) or a `NodeShape`. The `SelectQueryFactory` constructor handles both via its own resolution. The replacement needs to handle both cases too — use the same `getShapeClass()` or just pass to `createProxiedPathBuilder()` which already handles ShapeClass input. - -**Key pitfall 2:** `processWhereClause()` is also called by `SelectQueryFactory` internally (lines 1312, 1353, 1578, 1585, 1617, 1827). After deleting `LinkedWhereQuery`, these internal calls must still work.

Replace with a lightweight duck-typed object that satisfies the `isSelectQueryFactory` check in `FieldSet.convertTraceResult()`. - -**Depends on:** Phase 9 - -**Files expected to change:** -- `src/queries/SelectQuery.ts` — `QueryShapeSet.select()` (~line 1318), `QueryShape.select()` (~line 1485) - -#### Architecture - -Currently `QueryShapeSet.select()` (line 1318-1325) and `QueryShape.select()` (line 1485-1497) create `new SelectQueryFactory(leastSpecificShape, subQueryFn)` and set `.parentQueryPath`. The `SelectQueryFactory` constructor: -1. Calls `createProxiedPathBuilder(shape)` to build a proxy -2. Passes the proxy to `subQueryFn` to trace the sub-query -3. Stores the result as `this.traceResponse` - -`FieldSet.convertTraceResult()` (line 441) then detects this via `isSelectQueryFactory()` (line 33: checks for `getQueryPaths` function and `parentQueryPath` property) and extracts `parentQueryPath`, `traceResponse`, and `shape`. - -Replace with a plain object carrying the same duck-type interface: - -```typescript -select(subQueryFn: QueryBuildFn) { - const leastSpecificShape = this.getOriginalValue().getLeastSpecificShape(); - const proxy = createProxiedPathBuilder(leastSpecificShape); - const traceResponse = subQueryFn(proxy as any); - return { - parentQueryPath: this.getPropertyPath(), - traceResponse, - shape: leastSpecificShape, - getQueryPaths() { - throw new Error('Legacy getQueryPaths() not supported — use FieldSet path'); - }, - } as any; -} -``` - -**Key pitfall:** The `SelectQueryFactory` constructor does more than just trace — it also handles `selectAll` mode (no callback), and the traceResponse can be an array or single value. Verify that `subQueryFn(proxy)` produces the same `traceResponse` shape as `SelectQueryFactory`'s constructor would. Specifically: -- The proxy passed to `subQueryFn` must be the same type that `SelectQueryFactory` would pass — a `ProxiedPathBuilder` that returns `QueryBuilderObject`, `QueryShape`, `QueryShapeSet`, etc. -- `createProxiedPathBuilder(leastSpecificShape)` should work if `leastSpecificShape` is a ShapeClass. Verify. - -**Key pitfall 2:** `getQueryPaths()` is still called by the legacy `SelectQueryFactory.getQueryPaths()` path (line 1897: `if (endValue instanceof SelectQueryFactory)`). Since we're replacing with a plain object, `instanceof` checks will fail — but this is fine because the FieldSet path (which doesn't use `getQueryPaths()`) is now primary. However, if `_buildFactory()` is still active for some paths, it might call `getQueryPaths()` on the sub-query. The `throw` in `getQueryPaths()` will trigger the try/catch fallback in `toRawInput()`. This is acceptable during the transition — 10e removes `_buildFactory()` entirely. - -#### Tasks - -1. **Update `QueryShapeSet.select()`** (SelectQuery.ts ~line 1318-1325): - - Replace `new SelectQueryFactory(leastSpecificShape, subQueryFn)` with lightweight object - - Use `createProxiedPathBuilder(leastSpecificShape)` to get proxy - - Call `subQueryFn(proxy)` to trace - - Return plain object with `parentQueryPath`, `traceResponse`, `shape`, `getQueryPaths()` -2. **Update `QueryShape.select()`** (SelectQuery.ts ~line 1485-1497): - - Same replacement. Note: uses `getShapeClass((this.getOriginalValue() as Shape).nodeShape.id)` to get the shape class — keep this resolution logic. -3. **Verify `isSelectQueryFactory()` still matches** — the duck-type check requires `typeof obj.getQueryPaths === 'function'` and `'parentQueryPath' in obj`. The lightweight object has both. ✓ -4. **Verify `FieldSet.convertTraceResult()` handles it** — it reads `obj.parentQueryPath`, `obj.traceResponse`, `obj.shape`. All present on lightweight object. ✓ -5. **Remove `SelectQueryFactory` import** from proxy handler section if no other code in that scope needs it - -**Stubs for parallel execution:** None needed. The lightweight object satisfies the same duck-type interface that `FieldSet.convertTraceResult()` expects.

Remaining casts are inherent to proxy/dynamic patterns. -8. ✅ Clone type preservation — `clone()` returns properly typed `QueryBuilder` with full generic propagation -9. ✅ `PropertyPath.segments` defensive copy — TypeScript `readonly` annotation is sufficient -10. ⚠️ `FieldSet.traceFieldsFromCallback` removal — still exists as fallback (line 157 in FieldSet.ts); ProxiedPathBuilder is primary but old code kept as fallback for NodeShape-only paths - -#### Validation - -Per-item validation — each item gets its own commit with: -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass -- For item 7 (cast reduction): `grep -c 'as any\|as unknown' src/queries/*.ts` count < 10 - ---- - -### Phase 12: Typed FieldSet — carry response type through sub-selects ✅ - -**Status: Complete.** - -FieldSet now carries `` generics with phantom `declare` fields. `forSubSelect()` factory preserves types. `QueryShapeSet.select()` and `QueryShape.select()` return typed `FieldSet`. All conditional types migrated from `SubSelectResult` to pattern-match on `FieldSet`. `SubSelectResult` eliminated from codebase. 20 deep-nesting type probe tests + 7 FieldSet type tests pass. - -**Goal:** Make `FieldSet` the typed carrier for sub-select results, eliminating the need for the `SubSelectResult` type-only interface. After this phase, the type inference for sub-selects flows through `FieldSet` generics instead of a separate structural interface. - -**Motivation:** Currently sub-selects (`.select()` on QueryShapeSet/QueryShape) return plain objects typed as `SubSelectResult`. This interface exists *only* for conditional type pattern-matching — at runtime, these objects are ad-hoc literals that get converted to FieldSets anyway. FieldSet already has an unused `R` generic parameter (`class FieldSet`). By wiring up this generic and adding a `Source` parameter, FieldSet can carry the same type information and the conditional types can pattern-match on `FieldSet` directly. - -**Key insight:** The proxy callbacks (`QueryBuildFn`) already produce fully typed results. The `traceResponse` (callback return value) carries all type information. Today it's stored on `SubSelectResult.traceResponse`; after this phase it will be stored on `FieldSet.traceResponse` (or inferred from the generic). - -#### Background: Current flow - -```typescript -// 1. User writes: -p.friends.select(f => ({ name: f.name, age: f.age })) - -// 2. QueryShapeSet.select() returns: -SubSelectResult> - -// 3. Conditional types pattern-match on SubSelectResult to infer: -// Response = { name: QueryString, age: QueryNumber } -// Source = QueryShapeSet<...> → result is array - -// 4. At runtime, the returned object is a plain literal { traceResponse, parentQueryPath, shape, getQueryPaths() } -// which gets converted to a FieldSet when consumed by QueryBuilder -``` - -#### Target flow - -```typescript -// 1. User writes (same): -p.friends.select(f => ({ name: f.name, age: f.age })) - -// 2. QueryShapeSet.select() returns: -FieldSet<{ name: QueryString, age: QueryNumber }, QueryShapeSet> - -// 3. Conditional types pattern-match on FieldSet to infer: -// Response = { name: QueryString, age: QueryNumber } -// Source = QueryShapeSet<...> → result is array - -// 4. At runtime, select() directly constructs a FieldSet (no intermediate plain object) -``` - -#### Phase 12a: Add Source generic to FieldSet - -**Files:** `src/queries/FieldSet.ts` - -Add a second generic parameter `Source` to FieldSet: - -```typescript -// Before: -export class FieldSet { - readonly shape: NodeShape; - readonly entries: readonly FieldSetEntry[]; - -// After: -export class FieldSet { - readonly shape: NodeShape; - readonly entries: readonly FieldSetEntry[]; - /** Phantom field for conditional type inference of response type */ - declare readonly __response: R; - /** Phantom field for conditional type inference of source context */ - declare readonly __source: Source; -``` - -Using `declare` ensures no runtime cost — these are compile-time-only fields. - -**Validation:** -- `npx tsc --noEmit` exits 0 -- `npm test` — all 614 tests pass -- No runtime behavior changes — purely additive type change - -#### Phase 12b: Wire up FieldSet.for() to propagate Source generic - -**Files:** `src/queries/FieldSet.ts` - -Update the `FieldSet.for()` callback overload to accept an optional Source parameter: - -```typescript -// The callback overload already infers R: -static for(shape: ShapeType, fn: (p: any) => R): FieldSet - -// Add a Source-aware factory for sub-selects: -static forSubSelect( - shape: ShapeType, - fn: (p: any) => R, - parentPath: QueryPath, -): FieldSet { - const entries = FieldSet.traceFieldsWithProxy(shape.shape || shape, fn); - const fs = new FieldSet(shape.shape || shape, entries); - (fs as any)._parentPath = parentPath; - return fs as FieldSet; -} -``` - -Also update `createFromEntries` to preserve generics: - -```typescript -static createFromEntries( - shape: NodeShape, entries: FieldSetEntry[] -): FieldSet { - return new FieldSet(shape, entries) as FieldSet; -} -``` - -**Validation:** -- `npx tsc --noEmit` exits 0 -- `npm test` — all 614 tests pass - -#### Phase 12c: Update QueryShapeSet.select() and QueryShape.select() to return FieldSet - -**Files:** `src/queries/SelectQuery.ts`, `src/queries/FieldSet.ts` - -Change the `.select()` methods to construct and return typed FieldSets instead of plain objects: - -```typescript -// Before (QueryShapeSet.select): -select( - subQueryFn: QueryBuildFn, -): SubSelectResult> { - // ...builds plain object with traceResponse, parentQueryPath, shape, getQueryPaths() - return { ... } as any; -} - -// After: -select( - subQueryFn: QueryBuildFn, -): FieldSet> { - const leastSpecificShape = this.getOriginalValue().getLeastSpecificShape(); - const parentPath = this.getPropertyPath(); - return FieldSet.forSubSelect>( - leastSpecificShape, - subQueryFn as any, - parentPath, - ); -} -``` - -Same pattern for `QueryShape.select()`, changing `SubSelectResult` → `FieldSet`. - -Also update `selectAll()` return types accordingly. - -**Critical:** The FieldSet must still expose `getQueryPaths()` and `parentQueryPath` for compatibility with `BoundComponent.getComponentQueryPaths()` and `fieldSetToSelectPath()`. Add these as computed properties or methods on FieldSet. - -**Validation:** -- `npx tsc --noEmit` exits 0 -- `npm test` — all 614 tests pass -- Type probe file compiles with same inferred types - -#### Phase 12d: Migrate conditional types from SubSelectResult to FieldSet - -**Files:** `src/queries/SelectQuery.ts`, `src/queries/SubSelectResult.ts` - -Update all 8 conditional type pattern matches to match on `FieldSet` instead of `SubSelectResult`: - -```typescript -// Before: -export type GetQueryResponseType = - Q extends SubSelectResult ? ResponseType : Q; - -// After: -export type GetQueryResponseType = - Q extends FieldSet ? ResponseType : Q; -``` - -```typescript -// Before: -T extends SubSelectResult - ? GetNestedQueryResultType - -// After: -T extends FieldSet - ? GetNestedQueryResultType -``` - -Full list of pattern matches to update: -1. `QueryWrapperObject` (line 60) — `SubSelectResult` → `FieldSet` -2. `GetCustomObjectKeys` (line 289) — `T[P] extends SubSelectResult` → `T[P] extends FieldSet` -3. `ToQueryResultSet` (line 296) — extract ShapeType and ResponseType from FieldSet -4. `QueryResponseToResultType` (line 310) — extract Response and Source from FieldSet -5. `GetQueryObjectProperty` (line 396) — extract SubSource from FieldSet -6. `GetQueryObjectOriginal` (line 406) — extract SubResponse and SubSource from FieldSet -7. `GetQueryResponseType` (line 598) — extract ResponseType from FieldSet -8. `GetQueryShapeType` (line 601) — extract ShapeType from FieldSet (needs shape generic) - -**Challenge for #8:** `GetQueryShapeType` currently extracts `S` (Shape type) from `SubSelectResult`. FieldSet doesn't currently have an `S` generic — its shape is stored as `NodeShape`, not `ShapeType`. Options: -- Add a third generic `S` to FieldSet: `FieldSet` — adds complexity -- Store `ShapeType` on FieldSet alongside `NodeShape` — mirrors SubSelectResult -- Keep `GetQueryShapeType` pattern-matching on SubSelectResult as a temporary bridge - -**Recommendation:** If `GetQueryShapeType` is only used in a few places, check if those usages can be refactored. Otherwise add `ShapeType` storage to FieldSet. - -**Validation:** -- `npx tsc --noEmit` exits 0 -- `npm test` — all 614 tests pass -- Type probe file `type-probe-4.4a.ts` compiles and produces identical inferred types -- `grep -rn 'SubSelectResult' src/` — zero hits in conditional types (only in deprecated alias) - -#### Phase 12e: Delete SubSelectResult interface - -**Files:** `src/queries/SubSelectResult.ts`, `src/queries/SelectQuery.ts` - -Once all conditional types match on FieldSet: -1. Remove the `SubSelectResult` interface from `SubSelectResult.ts` -2. Keep the deprecated `SelectQueryFactory` alias pointing to `FieldSet` if external consumers use it, or delete entirely -3. Remove re-exports from `SelectQuery.ts` -4. Delete `SubSelectResult.ts` if empty - -**Validation:** -- `grep -rn 'SubSelectResult' src/` — zero hits (or only in deprecated alias) -- `npx tsc --noEmit` exits 0 -- `npm test` — all 614 tests pass -- Type probe file compiles - -#### Phase 12 — Dependency Graph - -``` -Phase 12a (Add Source generic) - ↓ -Phase 12b (Wire up FieldSet.for/createFromEntries) - ↓ -Phase 12c (select() returns FieldSet) - ↓ -Phase 12d (Migrate conditional types) - ↓ -Phase 12e (Delete SubSelectResult) -``` - -Strictly sequential — each phase builds on the previous. - -#### Risks and Considerations - -1. **FieldSet is a class, SubSelectResult is an interface** — TypeScript conditional types with `extends` work on both, but `FieldSet` is nominal (class) while `SubSelectResult` was structural (interface). The conditional type `T extends FieldSet` will match actual FieldSet instances. This is correct since after 12c, `.select()` returns real FieldSets. - -2. **`getQueryPaths()` and `parentQueryPath`** — These are currently on SubSelectResult but not on FieldSet. Phase 12c must add them (either as methods/getters or stored properties) so that existing code in `BoundComponent`, `isSubSelectResult` duck-checks, and `fieldSetToSelectPath` continues to work. FieldSet already has `entries` which can produce query paths via `fieldSetToSelectPath()`, so `getQueryPaths()` can be a computed method. - -3. **`traceResponse` field** — SubSelectResult stores `traceResponse` (the raw callback return). FieldSet currently doesn't store this — it processes it into entries during construction. For the phantom `__response` type to work, we don't need the runtime value, just the `declare` field. But `extractSubSelectEntriesPublic` uses `traceResponse` at runtime. Two options: - - Store `traceResponse` on FieldSet (adds runtime field) - - Process it eagerly during `forSubSelect()` construction (cleaner — no raw trace needed after construction) - - **Recommendation:** Process eagerly. The FieldSet already processes the trace into entries in `for()`, so `forSubSelect()` should do the same. - -4. **Duck-type check in FieldSet.ts** — `isSubSelectResult()` checks for `getQueryPaths` and `parentQueryPath`. After 12c, sub-selects return FieldSet instances. The duck-type check should be updated to `obj instanceof FieldSet` (possible since FieldSet.ts owns the class) or kept as structural check with updated comment. - -5. **Backward compatibility** — The deprecated `SelectQueryFactory` alias can be updated to point to `FieldSet` with matching generics: `type SelectQueryFactory = FieldSet`. Shape parameter `S` is lost but may be acceptable for deprecated usage. - -6. **`getQueryPaths` monkey-patch cleanup** — In `SelectQuery.ts` (BoundComponent.select and BoundShapeComponent.select), `getQueryPaths` is assigned onto the FieldSet instance via runtime monkey-patch after construction (lines ~1301-1307 and ~1481-1487). This is legacy glue from the old SubSelectResult setup. It should be factored into the FieldSet class itself (e.g. as a method on `forSubSelect`) so that the assignment happens inside the class rather than externally. - ---- - -## Type System Review - -Conducted after Phases 11–12 and follow-up fix-ups. This section captures what's good, what's concerning, and what's bad in the current type system state. - -### What's Good - -- **Phantom types in FieldSet** — `declare readonly __response: R` carries type info with zero runtime cost. Clean pattern. -- **Proxy-based path tracing** — `ProxiedPathBuilder.ts` cleanly captures `p.friends.bestFriend.name` chains. -- **QueryBuilder generic flow** — `S` (shape), `R` (response), `Result` stay consistent through `.select()`, `.one()`, `.where()`, `.limit()`. -- **PromiseLike integration** — `await builder` works without losing types. -- **Type probe tests** — `type-probe-4.4a.ts` and `type-probe-deep-nesting.ts` cover 4+ levels of nesting, sub-selects, custom objects, inheritance. Solid coverage. - -### What's Concerning - -- **CreateQResult** (SelectQuery.ts:415–493) — 12+ levels of conditional nesting. There's a TODO comment saying "this must be simplified and rewritten" and "likely the most complex part of the type system". It recursively self-calls. -- **GetQueryObjectResultType** (SelectQuery.ts:324–370) — 10+ conditional branches. Hard to trace. -- **Silent `never` fallthrough** — `QueryResponseToResultType`, `GetQueryObjectResultType`, `ToQueryPrimitive` all end with `: never`. If a type doesn't match any branch, it silently becomes `never` instead of giving a useful error. -- **QResult's second generic** — `QResult` is completely unconstrained. Any garbage object type gets merged in. -- **Generic naming** — mostly consistent (`S`, `R`, `Source`, `Property`) but `QShapeType` vs `ShapeType` vs `T` appear inconsistently in the conditional types. - -### What's Bad - -- **~44 `as any` casts in production code** — the biggest cluster is `Shape.ts` (10 casts for static method factory bridging) and `SelectQuery.ts` (20+ casts for proxy construction, generic coercion, shape instantiation). - - **Root cause:** `ShapeType` (the class constructor type) and `typeof Shape` (the abstract base) don't align. Every `Shape.select()`, `Shape.update()`, `Shape.create()`, `Shape.delete()` starts with `this as any`. This is the single biggest type gap. -- **IRDesugar shape resolution** — `(query.shape as any)?.shape?.id` because `RawSelectInput.shape` is typed as `unknown`. The runtime value is actually always a `ShapeType` or `NodeShape`. - -### Commented-Out Dead Code (still present) - -| Location | What | -|---|---| -| SelectQuery.ts:1365–1370 | Old `where()` method | -| SelectQuery.ts:1402–1428 | Old property resolution, TestNode, convertOriginal | -| SelectQuery.ts:733–746 | Abandoned TestNode approach | -| SelectQuery.ts:1441, 1462 | Debug `console.error`, old proxy return | -| SelectQuery.ts:1729–1740 | Old countable logic | -| MutationQuery.ts:266–269 | Commented validation | -| ShapeClass.ts:137–161 | `ensureShapeConstructor()` entirely commented out | - -### Incomplete Features (TODOs) - -| Location | What | -|---|---| -| MutationQuery.ts:33 | "Update functions not implemented yet" | -| QueryContext.ts:8 | "should return NullQueryShape" | -| SelectQuery.ts:693–697 | Async shape loading | -| SelectQuery.ts:1615–1616 | Consolidate QueryString/Number/Boolean/Date into QueryPrimitive | - ---- - -## Proposed Phases: Type System Cleanup + Pipeline Improvements - -### Phase Dependency Graph - -``` -Phase 13 (Dead code removal) — independent -Phase 14 (Type safety quick wins) — independent -Phase 15 (QueryPrimitive consolidation) — independent -Phase 16 (CreateQResult simplification) — independent, benefits from 14 -Phase 17 (getQueryPaths cleanup) — depends on 13 (cleaner codebase) -Phase 18 (FieldSet → desugar direct) — depends on 17 (getQueryPaths resolved) -Phase 19 (Shape factory + as any) — depends on 14 (RawSelectInput typed) - -Parallel group A: 13, 14, 15 can run in parallel -Parallel group B: 16, 17 can run after group A -Sequential: 18 after 17, 19 after 14 -``` - ---- - -### Phase 13: Dead Code Removal ✅ - -**Status: Complete.** - -**Effort: Low | Impact: Clarity** - -Removed all commented-out dead code, debug `console.log(lim)`, stale "strange bug" TODO, and stripped `ensureShapeConstructor` commented body (kept passthrough stub — has 2 callers). 106 lines deleted, 0 functional changes, all 619 tests pass. - -| # | Task | -|---|---| -| 13.1 | Remove commented `where()` method (SelectQuery.ts:1365–1370) | -| 13.2 | Remove commented property resolution / TestNode / convertOriginal (SelectQuery.ts:1402–1428) | -| 13.3 | Remove abandoned TestNode approach (SelectQuery.ts:733–746) | -| 13.4 | Remove debug `console.error` and old proxy return (SelectQuery.ts:1441, 1462) | -| 13.5 | Remove old countable logic (SelectQuery.ts:1729–1740) | -| 13.6 | Remove commented validation (MutationQuery.ts:266–269) | -| 13.7 | Clean up `ensureShapeConstructor` — body is entirely commented out, function just does `return shape;`. Remove the commented body or the entire function if unused (ShapeClass.ts:137–161) | - -**Validation:** -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass, no regressions -- `grep -rn '// *const\|// *if\|// *let\|// *return\|// *throw\|console.error' src/queries/SelectQuery.ts src/queries/MutationQuery.ts src/utils/ShapeClass.ts` — confirm targeted blocks are gone - -**Resolved:** `ensureShapeConstructor` kept as passthrough stub (has 2 callers). "Strange bug" comment investigated — no longer reproducible, removed. - ---- - -### Phase 14: Type Safety Quick Wins ✅ - -**Status: Complete (14.1 + 14.3 done, 14.2 skipped — constraint cascades through SubProperties and conflicts with QueryResponseToResultType union).** - -Typed `RawSelectInput.shape` properly. Added branded error types for `never` fallthrough in conditional types. `QResult` constraint (14.2) deferred — cascading type issues. - ---- - -### Phase 15: QueryPrimitive Consolidation ✅ - -**Status: Complete.** - -Removed 4 empty subclasses (QueryString, QueryNumber, QueryBoolean, QueryDate). Made QueryPrimitive concrete. Updated all 8 constructor calls, 1 instanceof check, SetSize inheritance, ToQueryPrimitive type, and all conditional type branches. No backward-compat aliases (not needed — classes were not exported publicly). 47 lines deleted, all 619 tests pass. - -**Effort: Medium | Impact: Less code, simpler type surface** - -Merge `QueryString`, `QueryNumber`, `QueryBoolean`, `QueryDate` into `QueryPrimitive` (TODO at SelectQuery.ts:1615–1616). The UPDATE comment notes "some of this has started — Query response to result conversion is using QueryPrimitive only". - -| # | Task | -|---|---| -| 15.1 | Audit all usages of `QueryString`, `QueryNumber`, `QueryBoolean`, `QueryDate` in src/ and tests — list every call site | -| 15.2 | Replace each subclass usage with `QueryPrimitive`, `QueryPrimitive`, `QueryPrimitive`, `QueryPrimitive` | -| 15.3 | Remove the 4 empty subclass definitions | -| 15.4 | Update type probes to verify inference still works | -| 15.5 | Update any `instanceof QueryString` etc. checks to use `instanceof QueryPrimitive` with type narrowing | - -**Validation:** -- `npx tsc --noEmit` exits 0 -- Type probe files compile and produce identical inferred types -- `npm test` — all tests pass -- `grep -rn 'QueryString\|QueryNumber\|QueryBoolean\|QueryDate' src/` — zero hits (only in comments/changelogs if any) - -**Resolved:** Removed entirely (not public API). One `instanceof` check found and converted. - ---- - -### Phase 16: CreateQResult Simplification — DEFERRED - -Moved to **docs/ideas/011-query-type-system-refactor.md**. The types are stable, well-tested by type probes, and rarely modified. Risk of silently breaking type inference outweighs the readability benefit during a cleanup pass. Should be done as a dedicated effort with `.d.ts` before/after diffing. - ---- - -### Phase 17: getQueryPaths Monkey-Patch Cleanup ✅ - -**Status: Complete.** - -Discovered the monkey-patched `getQueryPaths` on FieldSet was dead code — `getComponentQueryPaths()` catches FieldSet via `instanceof` before the duck-type check, and `fieldSetToSelectPath` + `entryToQueryPath` already handle parent path nesting through the entry's `path.segments` + recursive `subSelect`. Removed the two monkey-patch assignments, the optional property declaration on FieldSet, and the related comment. The duck-type checks remain for QueryBuilder (which has `getQueryPaths` as a real method). All 619 tests pass, tsc clean. - -**Effort: Medium | Impact: Code health, enables Phase 18** - -Factor the `getQueryPaths` monkey-patch into the FieldSet class properly. Currently assigned externally at SelectQuery.ts:1301–1307 and 1481–1487. - -**Current state:** -- `FieldSet` declares `getQueryPaths?: () => any` (FieldSet.ts:195) -- Two call sites in `BoundComponent.select()` and `BoundShapeComponent.select()` monkey-patch it onto the instance after `FieldSet.forSubSelect()` -- Consumed via duck-type check: `typeof (query as any).getQueryPaths === 'function'` (SelectQuery.ts:964) -- Delegates to `fieldSetToSelectPath(fs)` with parent path prepended - -| # | Task | -|---|---| -| 17.1 | Add `parentQueryPath` as a proper stored property on FieldSet (already partially there via `forSubSelect` constructor) | -| 17.2 | Implement `getQueryPaths()` as a real method on FieldSet — computes from `fieldSetToSelectPath(this)` + `parentQueryPath` | -| 17.3 | Remove the monkey-patch assignments at SelectQuery.ts:1301–1307 and 1481–1487 | -| 17.4 | Remove the optional property declaration `getQueryPaths?: () => any` from FieldSet | -| 17.5 | Update the duck-type checks at SelectQuery.ts:964–965 to use `instanceof FieldSet` or call the method directly | - -**Validation:** -- `npx tsc --noEmit` exits 0 -- `npm test` — all tests pass -- `grep -rn 'fs.getQueryPaths =' src/` — zero hits (monkey-patch gone) -- `grep -rn 'getQueryPaths\b' src/queries/` — only method definition and legitimate call sites remain - -**Resolved:** Monkey-patch was dead code. Removed entirely. `getQueryPaths` kept on QueryBuilder only. - ---- - -### Phase 18: Remove Old SelectPath IR ✅ - -**Status: Complete.** - -Eliminated the `SelectPath` / `QueryPath` intermediate representation. `desugarSelectQuery()` now accepts FieldSet entries directly via `RawSelectInput.entries`. Removed `fieldSetToSelectPath()`, `entryToQueryPath()`, and the old `SelectPath`-based desugar path. The `QueryStep`/`PropertyQueryStep`/`SizeStep` types remain only for where-clause/sort paths (produced by proxy evaluation, not FieldSet). - -Implemented as Phase 18A–D: wrote `desugarFieldSetEntries()` direct conversion, switched QueryBuilder to use it, refactored preloads to store `preloadSubSelect` FieldSet, and removed old bridge functions. `toWhere()` and `toSortBy()` kept as-is (where/sort paths come from proxy evaluation, not FieldSet). `QueryStep`/`PropertyQueryStep`/`SizeStep` types remain only for where-clause/sort path representation. - -Additional cleanup committed separately: type-safe `toSelectionPath()` with proper `QueryStep` type guards instead of duck-typing. - ---- - -### Phase 19: Shape Factory Redesign + `as any` Reduction ✅ - -**Status: Complete.** - -Defined `ShapeConstructor` — a concrete (non-abstract) constructor type with `new` + static `shape`/`targetClass`. Replaced `ShapeType` everywhere. Cast count reduced from ~44 to ~31. `ShapeType` removed entirely. - -Files changed: Shape.ts, resolveShape.ts, QueryBuilder.ts, UpdateBuilder.ts, CreateBuilder.ts, DeleteBuilder.ts, UpdateQuery.ts, CreateQuery.ts, DeleteQuery.ts, SelectQuery.ts, ProxiedPathBuilder.ts, FieldSet.ts. - -Remaining ~31 `as any` casts are inherent to proxy/dynamic patterns (callback generics, dynamic property access by string key, private `clone()` access in `fromJSON`). - ---- - -### Future TODO (deferred — not part of current plan) - -| Item | Reason to defer | -|---|---| -| **MutationQuery update functions** (MutationQuery.ts:33) — callback-style updates like `Shape.update(entity, e => { e.name = 'Bob' })` | Feature work, not cleanup.
