Subject: [PATCH 001/100] fix(kibi): restore source-linked query and schema
 parity

- kb.pl: kb_entities_by_source/2 now checks sourceFile first, falls back to source
- checks.pl: normalize value_type before value_type_matches_field to fix false positives
- cli/schema: add sourceFile property and executable_for/verified_by/validates relationships
- tests: regression coverage for sourceFile lookup, typed-literal normalization, schema parity

+## Context
+
+Kibi Briefing v2 relied on a fast-path `file.edited` trigger that was susceptible to drift and stale state, especially when multiple files were edited or the context window diverged from the background worker's snapshot. Reliability issues were identified in complex multi-step sessions where the "briefing" state became detached from the actual agent workspace.
+
+## Decision
+
+We will implement a **Session-Local Reconcile** architecture for Kibi Briefing v3.
+
+1.  **Authoritative Inputs**: The briefing engine will treat the plugin-local **current-session** scope as the authoritative source of truth.
+2.  **Reconcile Model**: The plugin will implement a reconcile mechanism that compares the local session state (including uncommitted edits and session history) with the KB snapshot before generating a briefing.
+3.  **Baseline Clearing**: On branch switch or explicit session reset, the briefing state must be cleared to its baseline, ensuring no stale context persists.
+4.  **Multi-File Fingerprinting**: Context fingerprints will be calculated using a multi-file hash of all currently edited/dirty files in the session, rather than just the last edited file.
+5.  **Event Flow Preservation**:
+    - `file.edited` remains a fast-path hint to trigger a potential reconcile.
+    - `system.transform` remains text-only but may trigger a reconcile/fetch fallback if the current fingerprint is missing or stale.
+6.  **Fallback Preservation**: The `/brief-kibi` manual command remains the canonical escape hatch for users/agents to force a fresh briefing generation.
+7.  **MCP-Only Surface**: All briefing generation and reconciliation logic continues to be exposed via the `kb_briefing_generate` MCP tool. No forbidden CLI commands are introduced.
+
+## Rationale
+
+-   **Accuracy**: By grounding the briefing in the actual session state, we eliminate the primary source of drift.
+-   **Stability**: Multi-file fingerprinting ensures the briefing remains stable even as the agent bounces between related files.
+-   **Security**: Preserves the thin-host boundary (ADR-016) by keeping complex logic in the MCP/CLI layer while the plugin handles state synchronization.
+-   **Predictability**: Explicit baseline clearing prevents "context leakage" between different workstreams or branches.
+
+## Verification
+
+-   Verify that `kb_briefing_generate` accepts session-local state for reconciliation.
+-   Verify that context fingerprints accurately reflect the state of all dirty files in the session.
+-   Verify that switching branches triggers a complete clearing of the briefing cache.

+
+The OpenCode Kibi Briefing system must transition to a session-grounded reconcile model to ensure briefings remain accurate and reliable across complex multi-step agent workflows.
+
+1.  **Session-Local Authority**: Briefings must be generated based on the **current-session** state, including dirty files and session history, ensuring guidance matches the agent's actual environment.
+2.  **Reconcile Mechanism**: The plugin must reconcile the local session state with the KB snapshot. If the session state has diverged, the briefing must be regenerated or adjusted to maintain accuracy.
+3.  **Multi-File Fingerprinting**: Briefing triggers and cache keys must use a fingerprint derived from all currently active/edited files in the session to prevent stale guidance when bouncing between related files.
+4.  **Baseline Reset**: The briefing system must explicitly revert-to-baseline and clear all cached briefings on branch checkout or session termination.
+5.  **Event Flow**:
+    - `file.edited` continues to serve as a fast-path trigger for the reconcile cycle.
+    - `system.transform` remains the primary injection point for guidance, leveraging the reconciled briefing state.
+6.  **Manual Escape Hatch**: The `/brief-kibi` command must be preserved as the canonical manual refresh mechanism.
+7.  **MCP Constraint**: All briefing generation must continue to use the `kb_briefing_generate` MCP tool. Direct use of `kibi` CLI commands (init, sync, check, etc.) by agents is strictly forbidden.
+8.  **Toast Invariant**: Toast notification behavior from v2 must be preserved, but grounded in the new reconcile-ready state.

+**AND** the agent has uncommitted edits in `file_a.ts` and `file_b.ts`
+**WHEN** the agent edits `file_c.ts`
+**THEN** the plugin must calculate a context fingerprint based on the **current-session** state of all three files
+**AND** it must invoke the `kb_briefing_generate` MCP tool with the session state for **reconcile**
+**AND** if the briefing is updated, it must show the "Kibi brief ready" toast.
+
+**Scenario: Branch Switch — Cache is cleared, reverted to baseline**
+
+**GIVEN** a session with a cached Kibi briefing for `branch-a`
+**WHEN** the user switches to `branch-b`
+**THEN** the plugin must **revert-to-baseline** and clear all cached briefing artifacts
+**AND** the next prompt transformation must NOT include stale guidance from `branch-a`.
+
+**Scenario: Manual Force — /brief-kibi triggers fresh reconcile**
+
+**GIVEN** a session where the agent suspects the auto-briefing is stale or missing context
+**WHEN** the agent executes the `/brief-kibi` command
+**THEN** the plugin must force a fresh **reconcile** with the background worker
+**AND** the full briefing must be rendered even if a compact summary was previously shown.
+
+**Scenario: MCP-Only Enforcement — No CLI tools used**
+
+**GIVEN** an agent trying to refresh the KB briefing
+**WHEN** the agent considers using `kibi sync` or `kibi check`
+**THEN** the agent must instead use the `kb_briefing_generate` MCP tool
+**AND** the plugin guidance must never suggest forbidden CLI commands.

+
+Verification plan for the Session-Local Reconcile briefing architecture:
+
+1.  **Current-Session Coverage Test**: Verify that the briefing generator correctly includes all dirty files in the **current-session** fingerprinting logic.
+2.  **Reconcile Accuracy Test**: Verify that editing a second file correctly triggers a **reconcile** and updates the briefing if the combined context changes.
+3.  **Baseline Reset Test**: Verify that switching git branches triggers an immediate **revert-to-baseline** and cache clear, preventing branch-to-branch context leakage.
+4.  **Multi-file Fingerprint Stability**: Verify that the context fingerprint remains stable when edits are made across multiple files that are already part of the session scope.
+5.  **Manual Refresh Guarantee**: Verify that `/brief-kibi` forces a full **reconcile** even when an auto-briefing is already present.
+6.  **MCP Isolation Test**: Verify that no forbidden CLI commands (sync, init, check) are used or suggested in the v3 implementation or guidance.
+7.  **Performance Check**: Verify that the reconcile cycle (fingerprint + fetch) completes within the latency budget for `file.edited` events.
+

+Improve briefing reliability for programmatic file edits by adding session-delta reconciliation. The plugin now detects risky edits via both the `file.edited` event fast-path and a prompt-cycle fallback that reconciles the current session scope before building guidance. This ensures briefings are available even when programmatic Edit/Write tools bypass the host event bus.

-When the plugin detects an authoritative risky edit (`behavior_candidate` or `traceability_candidate` risk class), it automatically fetches a Kibi briefing from a background worker session via the `file.edited` event path. Auto-briefing is no longer deferred and provides immediate project context before you act.
+When the plugin detects an authoritative risky edit (`behavior_candidate` or `traceability_candidate` risk class), it automatically fetches a Kibi briefing from a background worker session. The plugin uses two complementary paths: the `file.edited` event hook as a fast-path hint, and prompt-cycle reconciliation as an authoritative fallback for programmatic edits that bypass the event bus. Auto-briefing is no longer deferred and provides immediate project context before you act.
 
 - **Automatic delivery**: Briefings appear in a toast notification and inside the guidance block headed `🧠 **Kibi briefing available**`.
 - **Contextual richness**: The briefing includes a summary and key source-linked bullets generated by the `kb_briefing_generate` MCP tool.

+Add shared brief configuration defaults for automatic TUI delivery across Kibi clients. The CLI now reads and exposes brief config from `.kb/config.json` with sensible boolean defaults (all enabled), the OpenCode plugin delivers idle brief summaries via toast notification with automatic prompt append and auto-submit, and the VS Code extension gates notifications by the shared brief policy. This provides a unified, zero-config experience for teams using multiple Kibi clients.

+
+The VS Code Kibi extension must support brief notifications gated by shared config to provide contextual guidance while respecting project-level policy.
+
+1.  **Channel Gating**: Brief notifications in VS Code must respect the shared `briefs.channels.vscode` flag in `.kb/config.json`. When disabled, no automatic brief notifications appear.
+
+2.  **Shared Policy**: The brief system uses `.kb/config.json` as the source of truth for channel enablement:
+    - `briefs.enabled`: Master switch for all brief functionality
+    - `briefs.channels.vscode`: VS Code channel toggle
+    - `briefs.channels.tui`: OpenCode TUI channel toggle
+
+3.  **Manual Access**: When VS Code channel is disabled or notifications are suppressed, users can still retrieve briefs manually via the `/brief-kibi` slash command in OpenCode.
+
+4.  **Notification Behavior**: When enabled, brief notifications appear as toast/notification in the VS Code UI with brief summary content.
+
+5.  **Graceful Degradation**: If brief generation fails or KB is uninitialized, the VS Code extension must not crash; it simply skips notification delivery.

+Verification plan for the VS Code channel-gated briefing system:
+
+1.  **VS Code Channel Enabled Test**: Verify that when `briefs.channels.vscode: true` in `.kb/config.json`, brief notifications appear in VS Code.
+
+2.  **VS Code Channel Disabled Test**: Verify that when `briefs.channels.vscode: false`, no automatic notifications appear in VS Code.
+
+3.  **Master Switch Test**: Verify that when `briefs.enabled: false`, all channels are disabled regardless of individual channel settings.
+
+4.  **Manual Retrieval Test**: Verify that `/brief-kibi` works regardless of VS Code channel setting.
+
+5.  **Graceful Degradation Test**: Verify that VS Code extension handles KB uninitialization or brief generation failures without crashing.
+
+6.  **Config Change Reactivity Test**: Verify that changing `.kb/config.json` is reflected in subsequent brief delivery decisions.

Subject: [PATCH 033/100] fix(opencode): refactor brief system to use real
 OpenCode plugin APIs

Replace hallucinated APIs (client.session, client.tui.showToast, etc.) with real ones:
- Use Bun shell $ instead of client.session for kibi CLI commands
- Use client.tui.toast instead of showToast/appendPrompt/clearPrompt/submitPrompt
- Update all tests to match real API shapes
- All 855 opencode tests now pass

BREAKING CHANGE: Tests that relied on fake APIs have been updated.

  * Delivers a Kibi briefing to the TUI via OpenCode client capabilities.

+ * Uses the REAL OpenCode plugin API:
+ * - client.tui.toast(payload) - legacy toast API
+ *
+ * Note: autoSubmit via appendPrompt/clearPrompt/submitPrompt is NOT supported
+ * because OpenCode doesn't provide these APIs.
  *
  * @param client - OpenCode client with optional TUI capabilities
  * @param envelope - Idle brief envelope containing briefing content
  * @param sharedPolicy - Shared brief policy from `.kb/config.json`
  * @param localConfig - Local OpenCode config with autoSubmit preference
- *
- * Delivery behavior:
- * - Returns early if sharedPolicy.briefs.channels.tui is false
- * - Shows toast if sharedPolicy.briefs.tui.toast is true
- * - If localConfig.autoSubmit is true: clearPrompt → appendPrompt('/brief-kibi') → submitPrompt()
- * - If localConfig.autoSubmit is false: appendPrompt('Kibi: <summary>. Full brief: /brief-kibi')
- * - Skips append/submit if envelope.briefing.promptBlock is empty or sharedPolicy.briefs.tui.appendPrompt is false

Subject: [PATCH 034/100] fix(opencode): correct audit log line filter in
 computeAuditDelta

The filter was looking for lines starting with 'changeset(' but the actual
audit log format wraps entries in 'assert(changeset(...))'. Changed to use
.includes('changeset(') to properly parse all audit entries.

This fixes a bug where idle brief generation would always report 0 changes
even when the audit log contained entries.

Subject: [PATCH 035/100] fix(opencode): restore real OpenCode plugin APIs
 (showToast, session.create/prompt)

Reverts incorrect refactoring that replaced real OpenCode APIs with workarounds:
- client.tui.showToast() instead of client.tui.toast()
- client.session.create/prompt() for MCP calls instead of Bun shell $
- client.tui.appendPrompt/clearPrompt/submitPrompt for autoSubmit

Also:
- Creates .opencode/kibi.json with all config defaults set to true
- Fixes response parsing to extract JSON from prompt response parts
- Updates all tests to match restored APIs

All 855 tests pass, build succeeds.

+Fix OpenCode toast delivery and structured logging behavior:
+
+- Remove raw HTTP `fetch()` fallback to `/tui/show-toast` and all associated `[KIBI-TRACE]` console.error noise from the toast transport path.
+- Repair `sendToast()` to use the official OpenCode SDK contract: prefers legacy `client.tui.toast(payload)` when available, otherwise uses `client.tui.showToast({ body: payload })`.
+- Add discriminated `SendToastResult` union (`delivered`, `unavailable`, `failed`) for explicit, testable toast outcomes.
+- Fix `makeToastClient()` to preserve bound TUI methods (`toast` and `showToast`) so `this` context is not lost.
+- Align logger contract: `info()` and `warn()` remain terminal-silent even when `client.app.log()` rejects; `error()` emits exactly one prefixed `console.error` without secondary spam from structured log rejection.
+- Update startup notifier to log truthful structured outcomes (`startup toast delivered`, `startup toast unavailable`, `startup toast delivery failed`) instead of `result: String(undefined)`.
+- Remove `serverUrl` parameter from toast call chains and `PluginInput` interface.
+- Add regression coverage at unit level (`packages/opencode/tests/toast.test.ts`) and built-artifact level (`documentation/tests/e2e/opencode-plugin-local.test.ts`).
+- Update README and DEV.md to document the repaired toast and logging contracts.

 - **Bootstrap path regression tests** (`documentation/tests/e2e/packed/opencode-bootstrap-paths.test.ts`): verifies healthy relocated-path workspaces (`kibi-docs/*` with `.kb/config.json`) do not emit false bootstrap warnings, and missing configured targets still emit exactly one real bootstrap warning.
 - **Release-gate verification** (`.github/workflows/publish.yml`): the `Opencode packed behavior verification` step runs packed tests against downloaded tarballs using `KIBI_TEST_TARBALLS`, ensuring the published artifact matches source behavior.
 - **Local e2e build freshness** (`package.json` `test:e2e:local`): ensures `packages/opencode/dist` is rebuilt before local e2e tests, preventing stale dist from breaking dogfood confidence.
+- **Toast transport contract tests** (`packages/opencode/tests/toast.test.ts`): verifies legacy `client.tui.toast(payload)` preference, SDK `client.tui.showToast({ body: payload })` wrapping, `SendToastResult` discriminated union outcomes (`delivered`, `unavailable`, `failed`), timeout handling, and absence of raw HTTP fetch fallback or `console.error` trace noise.
+- **Startup toast structured outcome tests** (`packages/opencode/tests/startup-notifier.test.ts`): verifies truthful structured logging for toast delivery results (`startup toast delivered`, `startup toast unavailable`, `startup toast delivery failed`) without `console.error` leakage.
+- **Logger contract tests** (`packages/opencode/tests/logger.test.ts`): verifies advisory paths (`info`, `warn`, `errorStructuredOnly`) remain terminal-silent even when `client.app.log()` rejects, and operational `error()` emits exactly one prefixed `console.error` without secondary spam from structured log rejection.
+- **Built-artifact toast regression** (`documentation/tests/e2e/opencode-plugin-local.test.ts`): imports `packages/opencode/dist/toast.js` directly and asserts the compiled artifact uses the structured SDK contract with no raw fallback.

 ### Non-Blocking UX
 
 - Sync runs in background, never blocks OpenCode
-- Failures reported via console logs only, never as blocking UI elements
+- **Non-blocking toast delivery**: Toast transport is best-effort. The plugin detects available OpenCode TUI capabilities (`client.tui.toast` or `client.tui.showToast`) and uses the official SDK contract. Toast failures resolve to structured `SendToastResult` objects (`delivered`, `unavailable`, `failed`) rather than throwing or falling back to raw HTTP requests.

+| **Operational (plugin)** | bootstrap-needed, sync failure, hook/init failure | `error()` | Yes, exactly one prefixed `console.error` (`[kibi-opencode]`) | Yes, via `client.app.log()` |
 | **Authoritative external** | git hooks, CLI checks | Outside plugin surface | N/A | N/A |
 
 ### Failure Routing Contract
 
 The logger exposes two error-level surfaces with distinct routing semantics:
 
-- **`error(msg, metadata?)`** — Operational plugin failures. Always emits to `console.error` for terminal visibility, plus `client.app.log()` when a client is bound. Use for bootstrap-needed, hook/init failures, and sync failures that require developer attention.
-- **`errorStructuredOnly(msg, metadata?)`** — Advisory background maintenance failures. Routes through `client.app.log()` only when a client is bound; completely silent when no client is bound (no `console.error` fallback). Use for scheduler check failures and degraded-mode latches.
+- **`error(msg, metadata?)`** — Operational plugin failures. Emits exactly one prefixed `console.error` (`[kibi-opencode]`) for terminal visibility, plus `client.app.log()` when a client is bound. Structured log rejection does not emit secondary console noise. Use for bootstrap-needed, hook/init failures, and sync failures that require developer attention.
+- **`errorStructuredOnly(msg, metadata?)`** — Advisory background maintenance failures. Routes through `client.app.log()` only when a client is bound and remains terminal-silent even when the structured transport rejects. Use for scheduler check failures and degraded-mode latches.
 
-**Contract rule:** Once `client` is bound (after `setClient()`), advisory logging MUST use `errorStructuredOnly()`. When no client is bound, `errorStructuredOnly()` is completely silent — it does not fall back to `console.error`.
+**Contract rule:** Once `client` is bound (after `setClient()`), advisory paths (`info()`, `warn()`, `errorStructuredOnly()`) MUST stay on `client.app.log()` and remain terminal-silent. Operational failures use `error()` for a single prefixed terminal emission without duplicating console output when structured logging rejects.
 
 Routine diagnostics route through [`client.app.log()`](https://opencode.ai/docs/plugins/) and never appear in the terminal. Only operational error-class events break terminal silence. This keeps the developer's workspace clean while preserving full visibility in structured logs for debugging.
 
+### Toast Transport Contract
+
+The plugin uses the official OpenCode toast APIs with automatic capability detection:
+
+1. **Legacy transport**: `client.tui.toast(payload)` — used when available in plugin context
+2. **SDK transport**: `client.tui.showToast({ body: payload })` — used as fallback
+3. **No capability**: Returns `{ status: "unavailable", reason: "missing-capability" }`
+
+All toast delivery is best-effort and non-blocking. The `sendToast` helper returns a discriminated `SendToastResult` union and never throws. There is no raw HTTP fallback.
+
 The `experimental.chat.system.transform` hook handles prompt injection (see [Hook Policy](#hook-policy)). The `chat.params` hook is compatibility-only and never carries prompt text.

+Document render-first idle briefing behavior and mark deprecated config keys. The OpenCode and VS Code READMEs now reflect the shift from notification-based delivery to render-first briefings. Several legacy configuration knobs (`briefs.tui.toast`, `briefs.tui.appendPrompt`, `ux.briefs.autoSubmit`) are now marked as deprecated/no-op for idle rendering while remaining parseable for compatibility. Shared channel gating in `.kb/config.json` remains the authoritative source of truth.

+The OpenCode Kibi Briefing system must transition to a render-first idle-delivery model. This contract replaces toast-gated delivery with persistent, render-ready envelopes that the TUI appends directly to the guidance block, ensuring briefings are immediately visible without user interaction or auto-submit configuration complexity.
+
+1.  **Render-First Delivery**: When an idle briefing is generated, it must be persisted as a JSON envelope in `.kb/briefs/*_brief.json`. The OpenCode TUI must detect these envelopes and automatically append the `briefing.promptBlock` to the guidance section of the next prompt cycle.
+2.  **Deprecation of Toast Gating**: The v3 "Toast Invariant" is deprecated. Delivery is no longer gated by or dependent on toast notifications. Briefings are delivered by rendering, not by notifying.
+3.  **TUI Auto-Append**: The TUI must append the full briefing block to the prompt without requiring an explicit "submit" or "auto-submit" action from the user.
+4.  **Envelope Persistence**: Briefings must be stored in the `.kb/briefs/` directory using the `IdleBriefEnvelope` schema. This directory serves as the canonical handoff point between the background producer and the TUI consumer.
+5.  **Channel Gating**: Delivery remains gated by `.kb/config.json` settings:
+    - `briefs.enabled`: Global kill-switch for all briefing generation.
+    - `briefs.channels.tui`: Specifically enables/disables the render-first path in the TUI.
+    - `briefs.channels.vscode`: Enables/disables delivery to the VS Code channel.
+6.  **Config Deprecation**: The following configuration keys are deprecated and ignored in v4:
+    - `briefs.tui.toast` (replaced by render-first)
+    - `briefs.tui.appendPrompt` (now mandatory/default behavior)
+    - `ux.briefs.autoSubmit` (now mandatory/default behavior)
+7.  **Manual Retrieval Path**: The `/brief-kibi` command must be retained as a manual retrieval path for agents to force a fresh briefing or recover context if the idle delivery is skipped.
+8.  **MCP-Only Generation**: All briefing generation must continue to use the `kb_briefing_generate` MCP tool.
+9.  **Baseline Integrity**: The system must clear the `.kb/briefs/` directory and reset to baseline on branch checkout or session termination.

+
+The VS Code Kibi extension must support a render-first auto-open contract for idle briefings, providing immediate visibility of contextual guidance when unread briefs are detected.
+
+1.  **Auto-Open Behavior**: When a new unread idle brief is detected and `briefs.channels.vscode` is enabled, the VS Code extension must automatically open the brief document in a new editor tab.
+    - This behavior replaces the notification-first "View Brief" click requirement from v1.
+    - Automatic opening is only triggered for unread briefs.
+
+2.  **Briefing Content**: The rendered document must include the full briefing body (`briefing.promptBlock`) and summary.
+
+3.  **Channel Gating**: Auto-open behavior must respect the shared configuration in `.kb/config.json`:
+    - `briefs.enabled`: Master switch for all brief functionality.
+    - `briefs.channels.vscode`: VS Code channel toggle. If false, automatic opening is suppressed.
+
+4.  **Manual Retrieval**: Users must still be able to retrieve and view briefs manually via:
+    - The `kibi.showLatestBrief` command (VS Code Command Palette).
+    - The `/brief-kibi` slash command in OpenCode.
+
+5.  **Graceful Degradation**: If brief generation fails, the KB is uninitialized, or the brief file is malformed, the extension must fail silently without crashing the VS Code host.

+Verification plan for the Render-First Idle Briefing contract:
+
+1.  **Render-First Append Test**: Verify that the presence of an `IdleBriefEnvelope` in `.kb/briefs/` causes the `promptBlock` to be injected into the next `system.transform` payload without manual intervention.
+2.  **Toast Deprecation Test**: Verify that no toast notifications are required or emitted for briefing delivery when following the v4 contract.
+3.  **Config Gating Test**: Verify that setting `briefs.channels.tui: false` in `.kb/config.json` successfully suppresses the auto-append behavior.
+4.  **Auto-Submit Ignored Test**: Verify that the system ignores the legacy `ux.briefs.autoSubmit` setting and always appends the brief when the TUI channel is enabled.
+5.  **Manual Command Stability**: Verify that `/brief-kibi` remains functional and provides the full briefing on-demand, bypassing any cached idle envelopes if necessary.
+6.  **Envelope Clean-up Test**: Verify that branch switches or session closures result in an empty `.kb/briefs/` directory.
+7.  **Schema Compliance Test**: Verify that the persisted JSON files in `.kb/briefs/` strictly adhere to the `IdleBriefEnvelope` interface defined in `packages/opencode/src/idle-brief-store.ts`.

+
+3.  **Content Rendering Test**: Verify that the opened document correctly renders the `promptBlock` and summary from the brief JSON.
+
+4.  **Channel Suppression Test**: Verify that when `briefs.channels.vscode: false`, no automatic document opening occurs.
+
+5.  **Manual Command Test**: Verify that `kibi.showLatestBrief` (VS Code) and `/brief-kibi` (OpenCode) correctly display the brief even when auto-open is disabled.
+
+6.  **Silent Failure Test**: Verify that corrupted brief files or missing KB initialization do not trigger error notifications or crashes in VS Code.

+- **`briefs.enabled`**: Master switch for all brief functionality (default: `true`)
+- **`briefs.channels.vscode`**: Enable/disable VS Code channel for brief notifications (default: `true`)
+- **`briefs.channels.tui`**: Enable/disable OpenCode TUI channel for brief delivery (default: `true`)
+
+**Note on Deprecated Config**: The following keys are deprecated and no-op for idle rendering as part of the render-first migration:
+- `briefs.tui.toast`
+- `briefs.tui.appendPrompt`
+- `ux.briefs.autoSubmit`
+
+These remain parseable for backward compatibility but do not affect rendering. Shared channel gating remains the authoritative control in `.kb/config.json`.
+
+When a brief is available and the VS Code channel is enabled, the extension can display brief notifications. Use `/brief-kibi` in OpenCode for manual brief retrieval regardless of channel settings.

 Current workaround: static system prompt guidance directs agents to query Kibi explicitly.
 
+### File-Context Guidance
+
+The plugin provides proactive guidance when agents interact with specific files for the first time in a session:
+
+- **First-read focused guidance**: When an agent reads a file that has linked Kibi requirements (e.g., via `documentation/symbols.yaml`), the plugin injects a one-time reminder to check Kibi for that specific path.
+
+- **First-delete safety guidance**: When an agent attempts to delete a file, the plugin injects a safety check reminding the agent to verify if the file implements any Kibi requirements before removal.
+
+- **Session suppression**: To minimize prompt noise, this guidance is suppressed after the first occurrence per path per session.
+
+- **Current-host scope**: This feature uses host-side event monitoring to detect intent; it does not intercept or modify the actual file content returned by the Read tool.

Subject: [PATCH 040/100] feat(opencode): add unread idle brief reader

- Add idle-brief-reader.ts with selectLatestUnreadBrief and markBriefRead
- Use filename timestamp ordering (not mtime) for deterministic selection
- Atomic mark-read via temp file + rename
- Comprehensive tests for selection, filtering, and atomic updates

fix(opencode): stabilize idle brief cursor ordering

- Change getLatestAuditCursor to sort by filename timestamp instead of mtime
- Prevents mark-read rewrites from corrupting latest-brief selection
- Add regression test for ordering stability after read rewrite

Subject: [PATCH 041/100] feat(opencode): report idle brief append outcome

- Change deliverBriefTui to return DeliverResult { appended: boolean }
- Return appended=true only when appendPrompt succeeds
- Catch appendPrompt errors and return appended=false
- Update idle caller in index.ts to mark brief read only after successful append
- Add tests for success, failure, missing capability, and channel disabled

Subject: [PATCH 042/100] feat(opencode): replay unread idle briefs in tui

- Wire unread-brief replay into experimental.chat.system.transform
- selectLatestUnreadBrief now returns { envelope, filePath } for atomic mark-read
- Replay only latest unread brief for current branch
- Suppress duplicate replay per briefId via replayedBriefIds Set
- Mark brief read only after successful appendPrompt
- Replay not gated by maintenanceDegraded (brief already persisted)
- Add integration tests for replay, dedupe, failed append, degraded mode

docs(opencode): align briefing v4 replay contract

- Update REQ with prompt-time replay and read-state semantics
- Add SCEN for replay, failed delivery retry, branch isolation
- Update TEST plan with actual test file references
- Remove stale claims about session-end cleanup

-The OpenCode Kibi Briefing system must transition to a render-first idle-delivery model. This contract replaces toast-gated delivery with persistent, render-ready envelopes that the TUI appends directly to the guidance block, ensuring briefings are immediately visible without user interaction or auto-submit configuration complexity.
-
-1.  **Render-First Delivery**: When an idle briefing is generated, it must be persisted as a JSON envelope in `.kb/briefs/*_brief.json`. The OpenCode TUI must detect these envelopes and automatically append the `briefing.promptBlock` to the guidance section of the next prompt cycle.
-2.  **Deprecation of Toast Gating**: The v3 "Toast Invariant" is deprecated. Delivery is no longer gated by or dependent on toast notifications. Briefings are delivered by rendering, not by notifying.
-3.  **TUI Auto-Append**: The TUI must append the full briefing block to the prompt without requiring an explicit "submit" or "auto-submit" action from the user.
-4.  **Envelope Persistence**: Briefings must be stored in the `.kb/briefs/` directory using the `IdleBriefEnvelope` schema. This directory serves as the canonical handoff point between the background producer and the TUI consumer.
-5.  **Channel Gating**: Delivery remains gated by `.kb/config.json` settings:
-    - `briefs.enabled`: Global kill-switch for all briefing generation.
-    - `briefs.channels.tui`: Specifically enables/disables the render-first path in the TUI.
-    - `briefs.channels.vscode`: Enables/disables delivery to the VS Code channel.
-6.  **Config Deprecation**: The following configuration keys are deprecated and ignored in v4:
-    - `briefs.tui.toast` (replaced by render-first)
-    - `briefs.tui.appendPrompt` (now mandatory/default behavior)
-    - `ux.briefs.autoSubmit` (now mandatory/default behavior)
-7.  **Manual Retrieval Path**: The `/brief-kibi` command must be retained as a manual retrieval path for agents to force a fresh briefing or recover context if the idle delivery is skipped.
-8.  **MCP-Only Generation**: All briefing generation must continue to use the `kb_briefing_generate` MCP tool.
-9.  **Baseline Integrity**: The system must clear the `.kb/briefs/` directory and reset to baseline on branch checkout or session termination.
+The OpenCode Kibi Briefing system must transition to a render-first idle-delivery and prompt-time replay model. This contract ensures that briefings are reliably delivered by persisting render-ready envelopes at session idle and replaying unread briefs for the current branch during the next safe transform cycle.
+24#KW|
+25#SV|1.  **Render-First Idle Delivery**: When an idle briefing is generated at `session.idle`, it must be persisted as a JSON envelope in `.kb/briefs/*_brief.json`.
+26#KX|2.  **Prompt-Time Replay**: If immediate idle-time delivery was skipped (e.g., due to missing capabilities or disabled channels), the latest unread brief for the current branch must be surfaced on the next `experimental.chat.system.transform` cycle.
+27#JJ|3.  **Read-State Management**: A brief is marked `unread: false` only after successful delivery via `appendPrompt`. Failed or skipped delivery must leave the brief as `unread: true` for a later retry.
+28#XB|4.  **Latest-Only Replay**: Only the latest unread brief for the current branch is replayed; the system does not replay a backlog of briefs.
+29#WT|5.  **Branch Isolation**: Briefing selection is branch-aware. Only briefs generated for the current branch are considered for replay.
+30#JT|6.  **Channel Gating**: Delivery is gated by `.kb/config.json` settings:
+31#TM|    - `briefs.enabled`: Global kill-switch for all briefing generation.
+32#QV|    - `briefs.channels.tui`: Specifically enables/disables the render-first/replay path in the TUI.
+33#QV|7.  **Deterministic Selection**: The selection of the latest brief must use the filename timestamp rather than filesystem mtime to ensure consistency and avoid corruption from "mark-read" file rewrites.
+34#YY|8.  **Config Deprecation**: The following configuration keys are deprecated and ignored in v4:
+35#TP|    - `briefs.tui.toast` (replaced by render-first)
+36#HT|    - `briefs.tui.appendPrompt` (now mandatory/default behavior)
+37#XK|    - `ux.briefs.autoSubmit` (now mandatory/default behavior)
+38#HY|9.  **Manual Retrieval Path**: The `/brief-kibi` command remains available as a manual retrieval path to force a fresh briefing or recover context regardless of idle envelope state.
+39#RN|10. **MCP-Only Generation**: All briefing generation must continue to use the `kb_briefing_generate` MCP tool.

 Verification plan for the Render-First Idle Briefing contract:
 
-1.  **Render-First Append Test**: Verify that the presence of an `IdleBriefEnvelope` in `.kb/briefs/` causes the `promptBlock` to be injected into the next `system.transform` payload without manual intervention.
-2.  **Toast Deprecation Test**: Verify that no toast notifications are required or emitted for briefing delivery when following the v4 contract.

-5.  **Manual Command Stability**: Verify that `/brief-kibi` remains functional and provides the full briefing on-demand, bypassing any cached idle envelopes if necessary.
-6.  **Envelope Clean-up Test**: Verify that branch switches or session closures result in an empty `.kb/briefs/` directory.

Subject: [PATCH 046/100] fix(briefing): session-local counts, semantic dedupe,
 compact MCP, popup-first VS Code

Plan: kibi-briefing-issues

- Task 1: Add v3 VS Code and v5 OpenCode briefing contracts with supersedes links
- Task 2: Scope idle-brief counts to session-local baseline; fix summary wording
  ('entities changed' instead of 'requirements added')
- Task 3: Dedupe repeated delivery by normalized visible-content hash across
  TUI idle path, TUI replay path, and VS Code popup path
- Task 4: Keep kb_briefing_generate compact with truncation fallback; persist
  constraints, regressionRisks, missingEvidence through idle envelope
- Task 5: Keep VS Code popup-first; upgrade View Brief to 6-section narrative
  document (Overview, Session Summary, What Changed, Relevant KB Context,
  Validation Status, Next Step)
- Task 6: Add changeset for kibi-opencode and kibi-mcp; verify all tests pass

Verification:
- 2700 tests pass / 0 fail across 163 files
- All package typechecks pass
- F1-F4 Final Wave: ALL APPROVE

+Session-local baseline counts, semantic content-hash dedupe, compact promptBlock fallback, richer envelope fields, and VS Code popup-first UX. The OpenCode plugin now scopes audit deltas to the current session instead of cumulative branch totals, deduplicates briefs by normalized visible-content hash rather than briefId, and surfaces constraints, regression risks, and missing evidence in the envelope. The MCP server gracefully degrades the prompt block with compact truncation instead of returning empty content when over budget.

+
+The OpenCode Kibi Briefing system must transition to a session-local reconcile model with semantic duplicate suppression while preserving the render-first TUI delivery established in v4.
+
+1.  **Session-Local Baseline Counts**: The briefing engine must use session-local baseline counts instead of total historical branch totals.
+    - The first briefing in a new session must ignore unread briefs from previous sessions on the same branch.
+    - Briefing counters and change detections must be anchored to the state at session start.
+
+2.  **Normalized Content Duplicate Suppression**: Briefings must be suppressed if their normalized visible content matches a previously delivered brief in the current session.
+    - Suppression must use a hash of the normalized `promptBlock` content rather than just a `briefId`.
+    - Normalization must strip transient whitespace and session-specific metadata to ensure semantic equality.
+
+3.  **Render-First TUI Delivery**: The system must preserve the render-first delivery model where briefings are persisted as envelopes and replayed during `system.transform` if unread.
+
+4.  **Session Authoritativeness**: The plugin-local session scope (including uncommitted edits and session history) must be the authoritative source for reconciliation via `kb_briefing_generate`.
+
+5.  **Multi-File Fingerprinting**: Reconciliation must use multi-file fingerprinting of all currently edited/dirty files in the session to ensure briefing stability.
+
+6.  **Read-State Persistence**: Briefs must be marked as read only after successful TUI delivery. Semantic dedupe operates on the history of delivered (read) briefs within the session.
+
+7.  **Deterministic Selection**: Brief selection must continue to use filename timestamps for consistency.

+
+The VS Code Kibi extension must transition from auto-opening briefing documents to a popup-notification and manual-open model. This ensures that briefings are visible but non-intrusive, allowing users to choose when to engage with new contextual guidance.
+
+1.  **Popup Notifications**: When a new unread idle brief is detected and `briefs.channels.vscode` is enabled, the VS Code extension must display a non-modal popup notification (toast) instead of automatically opening the document.
+    - The notification must include an actionable "View Brief" button.
+    - Clicking "View Brief" must open the briefing document in a new editor tab.
+
+2.  **No Auto-Open**: The extension must NOT automatically open the brief document without a manual user action (either clicking the notification button or executing a command).
+
+3.  **Manual Retrieval**: Users must be able to retrieve and view briefings manually via:
+    - The `kibi.showLatestBrief` command from the VS Code Command Palette.
+    - The "View Brief" action in the popup notification.
+    - The `/brief-kibi` command in OpenCode (if applicable in shared contexts).
+
+4.  **Channel Gating**: Notification behavior must respect the shared configuration in `.kb/config.json`:
+    - `briefs.enabled`: Global switch for all brief functionality.
+    - `briefs.channels.vscode`: VS Code channel toggle. If false, all briefing notifications and auto-actions are suppressed.
+
+5.  **Unread Filtering**: Notifications are only triggered for briefs marked as unread.
+
+6.  **Graceful Degradation**: If the notification cannot be displayed or the manual open action fails, the extension must fail silently without impacting the VS Code host stability.

+Verification plan for Session-Local Reconcile and Semantic Dedupe:
+
+1.  **Baseline Reset Test**: Verify that starting a new session ignores the unread brief backlog from previous sessions.
+2.  **Semantic Dedupe Test**: Verify that briefings with identical normalized content (ignoring transient metadata) are suppressed within the same session.
+3.  **Multi-File Fingerprint Test**: Verify that the reconciliation logic correctly combines fingerprints from all dirty session files.
+4.  **TUI Delivery Regression Test**: Verify that new session-local briefs are still correctly replayed via the render-first TUI path.
+5.  **Normalization Verification**: Verify that the normalization algorithm correctly handles whitespace, line endings, and timestamp variations.

+Verification plan for the VS Code popup-first and manual-open briefing system:
+
+1.  **Notification Trigger Test**: Verify that a popup notification appears when a new unread brief is available and the VS Code channel is enabled.
+2.  **Actionable Notification Test**: Verify that clicking the "View Brief" action in the notification opens the correct briefing document.
+3.  **No Auto-Open Regression Test**: Verify that unread briefs do NOT automatically open editor tabs without user interaction.
+4.  **Channel Suppression Test**: Verify that no notifications or documents open when `briefs.channels.vscode: false`.
+5.  **Manual Command Test**: Verify that `kibi.showLatestBrief` remains functional and opens the latest brief even if the notification was dismissed.
+6.  **Silent Failure Test**: Verify that failures in notification display or document opening do not cause VS Code to crash or show unhandled errors.

+
+The OpenCode Kibi Plugin must provide proactive, contextual guidance based on host-side file lifecycle events (create, edit, delete) and established E2E evidence.
+
+### 1. File Lifecycle Guidance
+The plugin must monitor file lifecycle events and provide advisory-only reminders:
+- **Scope**: Lifecycle reminders are only eligible in `root_active` or `hybrid_root_plus_vendored` postures.
+- **Modifier Pattern**: Lifecycle events are treated as modifiers layered on top of existing semantic risk classification, not as a standalone `RiskClass`.
+- **Created/Edited**: When a file is created or edited, if it matches known symbol patterns or risky paths, the plugin must nudge the agent toward Kibi discovery.
+- **Deleted**: When a file is deleted, the plugin must inject a safety check reminding the agent to verify if the file implements any requirements or is linked to scenarios/tests.
+- **Suppression**: Guidance must be suppressed after the first occurrence per path per session to minimize prompt noise.
+
+### 2. E2E Evidence Verification
+The plugin must distinguish between authoritative E2E evidence and heuristic cues:
+- **Authoritative Evidence**: Exact E2E evidence requires a `covered_by -> TEST-*` relationship to an E2E-marked test entity.
+- **E2E Entity Definition**: A test entity is considered E2E if it has `tags: [e2e]` or a `source` path under an `/e2e/` directory.
+- **Heuristic Cues**: Heuristic E2E reminders may be used for exact path mentions in code but must remain soft-worded and clearly labeled as advisory.
+- **Package Umbrella Exclusion**: Generic package-level umbrella test documents are insufficient to count as exact E2E evidence for a specific file or symbol.
+
+### 3. Constraints
+- **Current-Host Only**: Guidance is based on host-side event monitoring; the plugin must not attempt first-read interception or modify file content returned by tools.
+- **Single-Block Policy**: All lifecycle and E2E guidance must be folded into the standard single-block prompt behavior defined in REQ-opencode-kibi-plugin-v1.
+- **Non-Blocking**: Guidance is advisory and must never block the agent's workflow.

+
+An agent is working in an OpenCode session with a `root_active` Kibi posture.
+
+### Steps
+1. **File Creation**: The agent creates a new file `src/auth/new-provider.ts`.
+2. **Detection**: The plugin detects the `file.created` event.
+3. **Guidance**: The plugin injects a soft-worded reminder in the prompt block to document the new file's intent in Kibi (e.g., via `REQ` or `FACT`).
+4. **File Deletion**: The agent deletes an existing file `src/legacy/utils.ts`.
+5. **Detection**: The plugin detects the `file.deleted` event.
+6. **Safety Check**: The plugin injects a reminder to verify if `src/legacy/utils.ts` had any `implements` or `covered_by` links that need cleanup or migration in Kibi.
+
+## Scenario: E2E Evidence Detection
+
+An agent is editing a file `src/app/core.ts`.
+
+### Steps
+1. **Graph Lookup**: The plugin queries the Kibi graph for `covered_by` relationships for symbols in `src/app/core.ts`.
+2. **Case A (Authoritative)**: A link is found to `TEST-e2e-auth-flow` which has `tags: [e2e]`.
+   - **Outcome**: Guidance explicitly states that authoritative E2E coverage exists.
+3. **Case B (Heuristic)**: No graph link is found, but the file path `src/app/core.ts` is mentioned in `tests/e2e/smoke.test.ts`.
+   - **Outcome**: Guidance provides a soft-worded heuristic reminder about potential E2E relevance.
+4. **Case C (Umbrella)**: The only link found is to a package-level `TEST-opencode-umbrella`.
+   - **Outcome**: Guidance does not claim exact E2E evidence.

+## Test Coverage
+
+### 1. Lifecycle Event Hooking
+- **Unit Test** (`packages/opencode/tests/lifecycle-guidance.test.ts`):
+  - Asserts that `file.created`, `file.edited`, and `file.deleted` events trigger guidance injection.
+  - Verifies that guidance is suppressed for `vendored_only` or `root_uninitialized` postures.
+  - Verifies session-based suppression after the first hit per path.
+
+### 2. E2E Evidence Logic
+- **Unit Test** (`packages/opencode/tests/e2e-evidence.test.ts`):
+  - Asserts that `covered_by` links to entities with `tags: [e2e]` are treated as authoritative.
+  - Asserts that `covered_by` links to entities with `source` under `/e2e/` are treated as authoritative.
+  - Verifies that heuristic path-matching results in soft-worded advisory text.
+  - Verifies that package-level umbrella tests do not trigger "authoritative evidence" flags.
+
+### 3. Prompt Integration
+- **Unit Test** (`packages/opencode/tests/prompt.test.ts`):
+  - Asserts that lifecycle guidance is merged into the single-block prompt output.
+  - Verifies that `RiskClass` is not mutated by lifecycle events (lifecycle is a modifier).
+
+### 4. Integration
+- **Integration Test** (`packages/opencode/tests/index.test.ts`):
+  - Verifies the full flow from host event to prompt injection in a simulated OpenCode environment.

-Add file-context guidance for first-read and first-delete operations. The plugin now provides proactive reminders when an agent interacts with source-linked files or attempts to delete them, helping maintain traceability and prevent accidental knowledge loss. Guidance is suppressed after the first occurrence per path per session.
+Add file-operation guidance for create, edit, and delete operations. The plugin now provides proactive reminders when agents create or edit source files with e2e evidence, and safety checks when deleting files that may implement Kibi requirements. Reminders use exact Kibi graph evidence first (covered_by links to [e2e]-tagged entities or /e2e/-sourced entities) and narrow path heuristics second. Package-level e2e tests do not trigger authoritative evidence flags at the file level. Guidance is suppressed after first occurrence per path per session.

+The plugin provides proactive guidance when agents perform file operations:
 
-- **First-read focused guidance**: When an agent reads a file that has linked Kibi requirements (e.g., via `documentation/symbols.yaml`), the plugin injects a one-time reminder to check Kibi for that specific path.
+- **File-create/edit guidance**: When an agent creates or edits a source file, the plugin may inject reminders to check Kibi for that path if e2e evidence exists.
 
-- **First-delete safety guidance**: When an agent attempts to delete a file, the plugin injects a safety check reminding the agent to verify if the file implements any Kibi requirements before removal.

-Add file-operation guidance for create, edit, and delete operations. The plugin now provides proactive reminders when agents create or edit source files with e2e evidence, and safety checks when deleting files that may implement Kibi requirements. Reminders use exact Kibi graph evidence first (covered_by links to [e2e]-tagged entities or /e2e/-sourced entities) and narrow path heuristics second. Package-level e2e tests do not trigger authoritative evidence flags at the file level. Guidance is suppressed after first occurrence per path per session.
+**Keep your knowledge base in sync without thinking about it.** This release makes the OpenCode plugin proactive about file operations — when you create, edit, or delete files, the plugin now nudges you to keep Kibi up to date automatically, rather than waiting for you to remember.
+
+**Smart reminders when files change.** Whenever you create a new source file, the plugin will gently remind you to add the corresponding Kibi entities and traceability links so nothing gets lost. When you edit files that have e2e test coverage, it prompts you to check whether your changes affect existing tests and whether the linked TEST entities need updates. And when you delete a file that implements requirements, it warns you to update Kibi so your documentation doesn't drift out of sync.
+
+**Evidence-driven, not noisy.** E2e reminders aren't guesswork — they look at actual Kibi graph relationships first. If a file has a `covered_by` link to a TEST entity tagged with `[e2e]` or sourced from the e2e directory, that's treated as concrete evidence. Only when exact evidence is absent does it fall back to narrow path heuristics, and even then the wording stays soft and advisory. Package-level umbrella tests never masquerade as file-level evidence, so you won't get false alarms.
+
+**Suppresses intelligently.** Once you've seen a reminder for a particular file in your session, it won't nag you again. Reminders are also posture-aware — they only appear when you're working in a fully initialized Kibi workspace (`root_active` or `hybrid_root_plus_vendored`), staying out of your way during onboarding or in vendored-only mode.
+
+**Background sync covers all lifecycle events.** The plugin's background sync now triggers not just on edits, but on file creation and deletion too. This closes the gap between the prompt advice you see and the actual freshness of your knowledge base, so Kibi stays current without you running manual syncs.
+
+**Everything stays single-block.** All of this fits into the existing one-contextual-block prompt design. There's no second block, no MCP queries during prompt assembly, and no new risk classes — just smarter, lifecycle-aware guidance layered on top of the semantic risk detection you already have.

-5. **Activation States**: The tool must classify the workspace state and only generate candidates when in a `root_uninitialized` or `root_partial` posture as defined in REQ-opencode-smart-enforcement-v1.
-6. **Payoff Reporting**: The tool should include a "payoff" estimate in the plan, describing the value of the proposed initialization (e.g., number of requirements linked, coverage improvements).
-7. **Read-Only Guarantee**: `kb_autopilot_generate` must be strictly read-only and must not modify the `.kb` directory or any documentation files.
+1. **Interactive Bootstrap Onboarding**: The `/init-kibi` workflow is defined as an interactive onboarding process. The agent must ask at most 4 bounded questions to gather declared context: project summary, primary source of truth, priority root (for monorepos), and verification/config anchors.
+2. **Read-Only Candidate Synthesis**: The `kb_autopilot_generate` tool must be strictly read-only. It synthesizes candidate Kibi entities (requirements, scenarios, tests, facts) and relationships based on the declared context and existing source evidence.
+3. **Declared Context vs. Verified Evidence**: The contract must distinguish between "declared context" (provided by the user via interactive questions) and "verified evidence" (discovered in the codebase). Synthesis should prioritize evidence but ground it in declared intent.
+4. **Agent-Managed Preview and Approval**: Agent-managed writes to the KB may only occur after the user has previewed and approved the proposed candidates. The MCP server must not apply changes autonomously.
+5. **Sequential Application**: Approved candidates must be applied using standard public MCP tools (`kb_upsert`) sequentially. After application, the agent must run `kb_check` to verify KB integrity.
+6. **No Pre-requisite Structure**: Bootstrap must not require existing `.kb/config.json`, `documentation/**`, or `symbols.yaml` to be present or structured to provide a useful onboarding experience.
+7. **MCP-Only Guidance**: All agent-facing bootstrap instructions must use MCP tools and sanctioned slash commands. Guidance must never suggest direct `kibi` CLI commands for maintenance.

+Automated verification for the interactive `/init-kibi` bootstrap includes:
 
-1. **Tool Registration Test**: Verify that the `kb_autopilot_generate` tool is correctly registered in the Kibi MCP server and its schema matches the requirement.
-2. **Read-Only Guarantee Test**: Verify that `kb_autopilot_generate` does not modify any files (no `kb_upsert` calls or file writes) even when it finds valid candidates.
-3. **Activation State Test**: Verify that `kb_autopilot_generate` correctly identifies and acts upon `root_uninitialized` and `root_partial` postures, returning an error or empty result for `root_active`.
-4. **Candidate Generation Prompt Content Test**: Verify that the generated `plan` and `candidates` correctly reflect the existing documentation structure in a sample repository.
-5. **Prompt Policy Compliance Test**: Verify that the generated plan does not contain direct CLI commands or suggest background-apply workflows.
-6. **Integration Test with kb_upsert**: Verify that the structured output from `kb_autopilot_generate` is directly compatible with `kb_upsert` input schema.
+1. **Interactive Workflow Test**: Verify that the `/init-kibi` prompt block instructs the agent to ask at most 4 bounded questions to gather declared context.
+2. **Read-Only Synthesis Test**: Verify that the `kb_autopilot_generate` tool correctly synthesizes candidate entities from declared context and codebase evidence without performing any writes.
+3. **Declared vs. Evidence Grounding Test**: Verify that synthesized candidates prioritize source evidence while remaining grounded in user-declared intent.
+4. **Preview and Approval Test**: Verify that the workflow requires a user-facing preview and explicit approval before any `kb_upsert` calls are made.
+5. **Sequential Application Test**: Verify that approved candidates are applied using `kb_upsert` in a deterministic, sequential order, followed by a full `kb_check`.
+6. **No-Prerequisite Bootstrap Test**: Verify that the bootstrap workflow produces a structured onboarding result even in repositories without existing `.kb/` or `documentation/` structures.
+7. **MCP-Only Policy Test**: Verify that no agent-facing text suggests direct `kibi` CLI usage for maintenance or initialization.

-**Keep your knowledge base in sync without thinking about it.** This release makes the OpenCode plugin proactive about file operations — when you create, edit, or delete files, the plugin now nudges you to keep Kibi up to date automatically, rather than waiting for you to remember.
-
-**Smart reminders when files change.** Whenever you create a new source file, the plugin will gently remind you to add the corresponding Kibi entities and traceability links so nothing gets lost. When you edit files that have e2e test coverage, it prompts you to check whether your changes affect existing tests and whether the linked TEST entities need updates. And when you delete a file that implements requirements, it warns you to update Kibi so your documentation doesn't drift out of sync.
-
-**Evidence-driven, not noisy.** E2e reminders aren't guesswork — they look at actual Kibi graph relationships first. If a file has a `covered_by` link to a TEST entity tagged with `[e2e]` or sourced from the e2e directory, that's treated as concrete evidence. Only when exact evidence is absent does it fall back to narrow path heuristics, and even then the wording stays soft and advisory. Package-level umbrella tests never masquerade as file-level evidence, so you won't get false alarms.
-
-**Suppresses intelligently.** Once you've seen a reminder for a particular file in your session, it won't nag you again. Reminders are also posture-aware — they only appear when you're working in a fully initialized Kibi workspace (`root_active` or `hybrid_root_plus_vendored`), staying out of your way during onboarding or in vendored-only mode.
-
-**Background sync covers all lifecycle events.** The plugin's background sync now triggers not just on edits, but on file creation and deletion too. This closes the gap between the prompt advice you see and the actual freshness of your knowledge base, so Kibi stays current without you running manual syncs.
-
-**Everything stays single-block.** All of this fits into the existing one-contextual-block prompt design. There's no second block, no MCP queries during prompt assembly, and no new risk classes — just smarter, lifecycle-aware guidance layered on top of the semantic risk detection you already have.

+2. **Read-Only Candidate Synthesis**: The `kb_autopilot_generate` tool must be strictly read-only. It may auto-create only safe deterministic entities and metadata (for example `symbol`, explicit `fact`, `adr`, and discovery metadata). `REQ`/`SCEN`/`TEST` authoring must be routed to the agent through `recommendedActions`, not auto-created from source-only evidence.
 3. **Declared Context vs. Verified Evidence**: The contract must distinguish between "declared context" (provided by the user via interactive questions) and "verified evidence" (discovered in the codebase). Synthesis should prioritize evidence but ground it in declared intent.
 4. **Agent-Managed Preview and Approval**: Agent-managed writes to the KB may only occur after the user has previewed and approved the proposed candidates. The MCP server must not apply changes autonomously.
 5. **Sequential Application**: Approved candidates must be applied using standard public MCP tools (`kb_upsert`) sequentially. After application, the agent must run `kb_check` to verify KB integrity.

+
+The OpenCode Kibi Briefing system must migrate to Schema-2.0 to support session-delta tracking, providing a high-fidelity audit of changes since the session began.
+
+1. **Session-Delta Baseline**: The briefing engine must use a session-start baseline captured at plugin initialization.
+    - Historical briefs from the same branch but previous sessions are ignored for change detection.
+    - Deltas represent the net change from session-start to the current state.
+
+2. **Schema-2.0 Contract**: Briefing envelopes must use `schemaVersion: "2.0"` and include the following structure:
+    - `counts: { entitiesAdded, entitiesModified, entitiesRemoved, relationshipsChanged }`
+    - `changes: { entities: { added, modified, removed }, relationships: { changed } }`
+    - The legacy `requirementsAdded` and other flat count fields are removed.
+
+3. **High-Fidelity Change Semantics**: The system must track exact entity lifecycle states:
+    - `added`: Entities created during the session.
+    - `modified`: Existing entities updated during the session.
+    - `removed`: Entities deleted during the session.
+    - `relationships.changed`: Any addition or removal of typed links.
+
+4. **Cited-First Narrative Narrative**: The `briefing.changeNarrative` field must be an ordered array of strings.
+    - Narrative generation must prioritize MCP-cited entities (those explicitly touched by tools).
+    - An audit fallback must catch any un-cited side effects detected in the KB delta.
+
+5. **Write Path Enforcement**: The system must write Schema-2.0 envelopes exclusively. Readers must tolerate Schema-1.0 envelopes during the migration window but prioritize 2.0 semantics.

-The VS Code Kibi extension must transition from auto-opening briefing documents to a popup-notification and manual-open model. This ensures that briefings are visible but non-intrusive, allowing users to choose when to engage with new contextual guidance.
+The VS Code Kibi extension must align with the Schema-2.0 briefing envelope and implement deterministic filename-timestamp ordering for latest-brief selection.
 
-1.  **Popup Notifications**: When a new unread idle brief is detected and `briefs.channels.vscode` is enabled, the VS Code extension must display a non-modal popup notification (toast) instead of automatically opening the document.
-    - The notification must include an actionable "View Brief" button.
-    - Clicking "View Brief" must open the briefing document in a new editor tab.
+1. **Schema-2.0 Alignment**: The extension must support rendering briefings that follow the Schema-2.0 structure.
+    - It must correctly interpret `counts` and `changes` fields for display in the brief editor tab.
+    - It must handle the `changeNarrative` string array for the primary narrative block.
 
-2.  **No Auto-Open**: The extension must NOT automatically open the brief document without a manual user action (either clicking the notification button or executing a command).
+2. **Deterministic Latest-Brief Selection**: Selection of the "latest" brief must use filename-timestamp ordering rather than filesystem modification time (`mtime`).
+    - Brief files are named using a sortable timestamp pattern (e.g., `brief-20260506-043000.json`).
+    - The extension must sort available brief files lexicographically by filename to determine the most recent one.
+    - This ensures consistent behavior across different environments and filesystems where `mtime` may be unreliable.
 
-3.  **Manual Retrieval**: Users must be able to retrieve and view briefings manually via:
-    - The `kibi.showLatestBrief` command from the VS Code Command Palette.
-    - The "View Brief" action in the popup notification.
-    - The `/brief-kibi` command in OpenCode (if applicable in shared contexts).
+3. **Auto-Open Preservation**: The render-first auto-open behavior established in v2 must be preserved and correctly triggered by the new deterministic selection logic.
 
-4.  **Channel Gating**: Notification behavior must respect the shared configuration in `.kb/config.json`:
-    - `briefs.enabled`: Global switch for all brief functionality.
-    - `briefs.channels.vscode`: VS Code channel toggle. If false, all briefing notifications and auto-actions are suppressed.
+4. **Graceful Schema Fallback**: During the migration window, the extension should tolerate Schema-1.0 envelopes but apply Schema-2.0 display logic where possible.
 
-5.  **Unread Filtering**: Notifications are only triggered for briefs marked as unread.
-
-6.  **Graceful Degradation**: If the notification cannot be displayed or the manual open action fails, the extension must fail silently without impacting the VS Code host stability.

+
+**Scenario: Relationship Change Tracking — Link delta visibility**
+
+**GIVEN** a new relationship is created between a symbol and a requirement
+**WHEN** the briefing is generated
+**THEN** `counts.relationshipsChanged` must reflect the change

+
+**Scenario: Schema Migration — v2.0 exclusive write**
+
+**GIVEN** the system is in a transition state
+**WHEN** a new briefing is persisted
+**THEN** it must follow the Schema-2.0 structure

+Verification plan for Schema-2.0 and Session-Delta migration:
+
+1. **Schema Validation Test**: Verify that generated briefing envelopes strictly follow the Schema-2.0 structure (counts, changes, changeNarrative, schemaVersion).
+2. **Session-Delta Accuracy Test**: Verify that entities added, modified, or removed during a session are correctly identified and counted against the session-start baseline.
+3. **Relationship Delta Test**: Verify that link changes are captured in the `relationshipsChanged` count and `changes.relationships.changed` list.
+4. **Narrative Ordering Test**: Verify that `changeNarrative` prioritize MCP-cited entities over audited side-effects.
+5. **Legacy Suppression Test**: Verify that legacy flat count fields (e.g., `requirementsAdded`) are absent from Schema-2.0 briefs.

-Verification plan for the VS Code popup-first and manual-open briefing system:
+Verification plan for Schema-2.0 and Deterministic Ordering in VS Code:
 
-1.  **Notification Trigger Test**: Verify that a popup notification appears when a new unread brief is available and the VS Code channel is enabled.
-2.  **Actionable Notification Test**: Verify that clicking the "View Brief" action in the notification opens the correct briefing document.
-3.  **No Auto-Open Regression Test**: Verify that unread briefs do NOT automatically open editor tabs without user interaction.
-4.  **Channel Suppression Test**: Verify that no notifications or documents open when `briefs.channels.vscode: false`.
-5.  **Manual Command Test**: Verify that `kibi.showLatestBrief` remains functional and opens the latest brief even if the notification was dismissed.
-6.  **Silent Failure Test**: Verify that failures in notification display or document opening do not cause VS Code to crash or show unhandled errors.
+1. **Deterministic Selection Test**: Verify that the extension correctly sorts brief files by filename and selects the latest one regardless of `mtime`.
+2. **Schema-2.0 Integration Test**: Verify that the brief editor correctly renders the `changeNarrative` array and `counts` fields from a Schema-2.0 envelope.
+3. **Auto-Open Regression Test**: Verify that unread Schema-2.0 briefs are automatically opened in a document tab when detected.
+4. **Filename Pattern Validation**: Verify that the extension correctly handles the `brief-YYYYMMDD-HHMMSS.json` filename pattern.

Subject: [PATCH 073/100] feat(briefing): schema-v2 migration, cited
 narratives, and deterministic ordering

- Migrate idle brief envelope to schema-2.0 (exact add/modify/remove counts)
- Feed idle brief generation real cited context with sourceFiles/seedIds
- Render schema-2.0 changeNarrative in TUI toast delivery
- Migrate VS Code parser/renderer to schema-2.0 with filename-timestamp ordering
- Add reconcile-engine for net semantic entity collapse
- Capture session-start baseline via session-fingerprint
- Enrich core audit with change_kind metadata
- Fix build errors and apply biome formatting

+Document the native `/init-kibi` alias as a thin OpenCode UX wrapper over the existing MCP bootstrap workflow.

+Improve idle-brief delivery timing and deduplication across OpenCode TUI and VS Code channels. The OpenCode plugin now syncs before idle briefing, waits for the idle work burst to settle, handles sync-only KB changes, and persists TUI-seen brief hashes so delivered briefs do not replay after restart while VS Code can still receive unread brief files.

@@ -115,9 +115,9 @@ OpenCode exposes Kibi MCP prompts as slash commands. The \`/init-kibi\` command
 
 When the plugin detects an authoritative risky edit (`behavior_candidate` or `traceability_candidate` risk class), it automatically renders a Kibi briefing before the prompt. The plugin uses two complementary paths: the `file.edited` event hook as a fast-path hint, and prompt-cycle reconciliation as an authoritative fallback for programmatic edits that bypass the event bus. Briefings are rendered directly into the prompt to ensure immediate visibility.
 
-- **Immediate delivery**: Briefings are rendered-first into the prompt guidance block headed `🧠 **Kibi briefing available**`.
-- **Contextual richness**: The briefing includes a summary and key source-linked bullets generated by the `kb_briefing_generate` MCP tool.
-- **TL;DR fallback**: If a full briefing is unavailable, a summary is provided with a cue to use the manual command.
+- **Immediate delivery**: Briefings are rendered-first into the prompt guidance block headed `🧠 **Kibi briefing available**` and TUI toasts titled `Kibi Knowledge Update`.
+- **Narrative structure**: Delivery favors user-facing prose with `What changed` and `Why it matters`, plus conditional `Project knowledge impact` / `Interpretation note` sections when evidence or caveats exist.
+- **TL;DR fallback**: If a full briefing is unavailable, fallback output still preserves `What changed` / `Why it matters` framing while keeping the manual command cue available.
 - **Manual command**: Use `/brief-kibi` at any time to trigger an on-demand briefing if auto-delivery is skipped or fails.

-Add shared brief configuration defaults for automatic TUI delivery across Kibi clients. The CLI now reads and exposes brief config from `.kb/config.json` with sensible boolean defaults (all enabled), the OpenCode plugin delivers idle brief summaries via toast notification with automatic prompt append and auto-submit, and the VS Code extension gates notifications by the shared brief policy. This provides a unified, zero-config experience for teams using multiple Kibi clients.

-Improve idle-brief delivery timing and deduplication across OpenCode TUI and VS Code channels. The OpenCode plugin now syncs before idle briefing, waits for the idle work burst to settle, handles sync-only KB changes, and persists TUI-seen brief hashes so delivered briefs do not replay after restart while VS Code can still receive unread brief files.

-Document render-first idle briefing behavior and mark deprecated config keys. The OpenCode and VS Code READMEs now reflect the shift from notification-based delivery to render-first briefings. Several legacy configuration knobs (`briefs.tui.toast`, `briefs.tui.appendPrompt`, `ux.briefs.autoSubmit`) are now marked as deprecated/no-op for idle rendering while remaining parseable for compatibility. Shared channel gating in `.kb/config.json` remains the authoritative source of truth.

-Document the native `/init-kibi` alias as a thin OpenCode UX wrapper over the existing MCP bootstrap workflow. When the plugin supports native command injection, `/init-kibi` is the canonical short alias; `/kibi:init-kibi:mcp` remains the namespaced fallback, and unsupported hosts fail closed with explicit guidance instead of pretending the alias exists.

-Improve briefing reliability for programmatic file edits by adding session-delta reconciliation. The plugin now detects risky edits via both the `file.edited` event fast-path and a prompt-cycle fallback that reconciles the current session scope before building guidance. This ensures briefings are available even when programmatic Edit/Write tools bypass the host event bus.

-Fix OpenCode toast delivery and structured logging behavior:
-
-- Remove raw HTTP `fetch()` fallback to `/tui/show-toast` and all associated `[KIBI-TRACE]` console.error noise from the toast transport path.
-- Repair `sendToast()` to use the official OpenCode SDK contract: prefers legacy `client.tui.toast(payload)` when available, otherwise uses `client.tui.showToast({ body: payload })`.
-- Add discriminated `SendToastResult` union (`delivered`, `unavailable`, `failed`) for explicit, testable toast outcomes.
-- Fix `makeToastClient()` to preserve bound TUI methods (`toast` and `showToast`) so `this` context is not lost.
-- Align logger contract: `info()` and `warn()` remain terminal-silent even when `client.app.log()` rejects; `error()` emits exactly one prefixed `console.error` without secondary spam from structured log rejection.
-- Update startup notifier to log truthful structured outcomes (`startup toast delivered`, `startup toast unavailable`, `startup toast delivery failed`) instead of `result: String(undefined)`.
-- Remove `serverUrl` parameter from toast call chains and `PluginInput` interface.
-- Add regression coverage at unit level (`packages/opencode/tests/toast.test.ts`) and built-artifact level (`documentation/tests/e2e/opencode-plugin-local.test.ts`).
-- Update README and DEV.md to document the repaired toast and logging contracts.

 # kibi-opencode
 
+## 0.10.0
+
+### Minor Changes
+
+- b9ef9a2: Add shared brief configuration defaults for automatic TUI delivery across Kibi clients. The CLI now reads and exposes brief config from `.kb/config.json` with sensible boolean defaults (all enabled), the OpenCode plugin delivers idle brief summaries via toast notification with automatic prompt append and auto-submit, and the VS Code extension gates notifications by the shared brief policy. This provides a unified, zero-config experience for teams using multiple Kibi clients.
+- 736f675: Add the interactive cold-start bootstrap flow and its regression coverage so the public MCP surface, OpenCode prompt wiring, and extractor exports stay in sync.
+- 3dd2c56: Document the native `/init-kibi` alias as a thin OpenCode UX wrapper over the existing MCP bootstrap workflow. When the plugin supports native command injection, `/init-kibi` is the canonical short alias; `/kibi:init-kibi:mcp` remains the namespaced fallback, and unsupported hosts fail closed with explicit guidance instead of pretending the alias exists.
+
+### Patch Changes
+
+- a1a198b: Add configurable idle-brief delay and retention policies in shared `.kb/config.json` (`briefs.tui.idleDelayMs` and `briefs.retention.*`). OpenCode now applies retention garbage collection after brief writes and prunes stale `.tui-seen` hashes for briefs that were deleted by retention.
+- 699a482: Create append-only contract documentation and release metadata for the Kibi briefing schema-2.0 session-delta migration. This update introduces high-fidelity change tracking anchored to the session start, prioritized change narratives for MCP-cited entities, and deterministic filename-based brief selection for VS Code.
+- efdacbc: Session-local baseline counts, semantic content-hash dedupe, compact promptBlock fallback, richer envelope fields, and VS Code popup-first UX. The OpenCode plugin now scopes audit deltas to the current session instead of cumulative branch totals, deduplicates briefs by normalized visible-content hash rather than briefId, and surfaces constraints, regression risks, and missing evidence in the envelope. The MCP server gracefully degrades the prompt block with compact truncation instead of returning empty content when over budget.
+- 7bcd57e: Improve idle-brief delivery timing and deduplication across OpenCode TUI and VS Code channels. The OpenCode plugin now syncs before idle briefing, waits for the idle work burst to settle, handles sync-only KB changes, and persists TUI-seen brief hashes so delivered briefs do not replay after restart while VS Code can still receive unread brief files.
+- 3aad975: Document render-first idle briefing behavior and mark deprecated config keys. The OpenCode and VS Code READMEs now reflect the shift from notification-based delivery to render-first briefings. Several legacy configuration knobs (`briefs.tui.toast`, `briefs.tui.appendPrompt`, `ux.briefs.autoSubmit`) are now marked as deprecated/no-op for idle rendering while remaining parseable for compatibility. Shared channel gating in `.kb/config.json` remains the authoritative source of truth.
+- 4000488: Improve briefing reliability for programmatic file edits by adding session-delta reconciliation. The plugin now detects risky edits via both the `file.edited` event fast-path and a prompt-cycle fallback that reconciles the current session scope before building guidance. This ensures briefings are available even when programmatic Edit/Write tools bypass the host event bus.
+- 4fe5c7e: Fix OpenCode toast delivery and structured logging behavior:
+
+  - Remove raw HTTP `fetch()` fallback to `/tui/show-toast` and all associated `[KIBI-TRACE]` console.error noise from the toast transport path.
+  - Repair `sendToast()` to use the official OpenCode SDK contract: prefers legacy `client.tui.toast(payload)` when available, otherwise uses `client.tui.showToast({ body: payload })`.
+  - Add discriminated `SendToastResult` union (`delivered`, `unavailable`, `failed`) for explicit, testable toast outcomes.
+  - Fix `makeToastClient()` to preserve bound TUI methods (`toast` and `showToast`) so `this` context is not lost.
+  - Align logger contract: `info()` and `warn()` remain terminal-silent even when `client.app.log()` rejects; `error()` emits exactly one prefixed `console.error` without secondary spam from structured log rejection.
+  - Update startup notifier to log truthful structured outcomes (`startup toast delivered`, `startup toast unavailable`, `startup toast delivery failed`) instead of `result: String(undefined)`.
+  - Remove `serverUrl` parameter from toast call chains and `PluginInput` interface.
+  - Add regression coverage at unit level (`packages/opencode/tests/toast.test.ts`) and built-artifact level (`documentation/tests/e2e/opencode-plugin-local.test.ts`).
+  - Update README and DEV.md to document the repaired toast and logging contracts.
+
+- Improve user-facing briefing delivery to emphasize domain-impact prose over operator metadata. This removes low-value sections (session/unread/next-step style cues), introduces consistent narrative sections (what changed, why it matters, project knowledge impact), and updates TUI/VSCode rendering to keep interpretation notes descriptive rather than directive.

 # Agent Guidelines for Kibi Project
 
-This document provides guidelines for AI agents working on the kibi codebase.
+This file is intentionally terse. It captures repo-specific operating rules for agents and avoids duplicating MCP tool schemas or long-form docs.
 
-## Project Overview
+## Source of Truth Hierarchy
 
-**Kibi** is a repo-local, per-branch, queryable long-term memory for software projects. It stores requirements, BDD scenarios, tests, architecture decisions (ADRs), feature flags, events, code symbols, and facts—along with typed relationships between them.
+1. MCP tool `inputSchema` enums/required fields (authoritative for tool contracts)
+2. `docs/mcp-reference.md` and `docs/entity-schema.md`
+3. This file (workflow and policy guardrails)
 
-The KB is accessible via:
-- **CLI**: `kibi` command-line tool for humans/operators and automation
-- **MCP Server**: For LLM agent integration via stdio (JSON-RPC)
+If this file and MCP schema details diverge, follow MCP schema and update this file.
 
----
+## Non-Negotiables
 
-## Entity Types
+- Use Kibi via MCP tools only.
+- Do **not** manually read or edit `.kb/` files.
+- Do **not** run `kibi` CLI from agent sessions unless explicitly required by the user/operator workflow.
+- If KB setup/repair is needed beyond `/init-kibi`, ask the user/operator to run those steps.
 
-Kibi supports eight core entity types, grouped by their primary purpose:
+## Required Kibi Workflow (Current Standard)
 
-### Common Authoring Entities (Standard Workflow)
-| Type | Description | ID Prefix | Status Values |
-|------|-------------|-----------|---------------|
-| `req` | Requirement | REQ-XXX | open, in_progress, closed, deprecated |
-| `scenario` | BDD behavior | SCEN-XXX | draft, active, deprecated |
-| `test` | Unit/integration/e2e test | TEST-XXX | passing, failing, skipped, pending |
-| `fact` | Atomic domain fact; includes strict lanes and observation/meta notes | FACT-XXX | active, deprecated |
+1. **Bootstrap day-0 with `/init-kibi`**
+   - Ask at most 4 bounded context questions.
+   - Use `kb_autopilot_generate` for read-only synthesis.
+   - Show preview and get explicit approval before writes.
+   - Apply approved writes via sequential `kb_upsert`.
+   - Run `kb_check` after applying.
 
-### Supporting & System Entities (Context & Infrastructure)
-| Type | Description | ID Prefix | Status Values |
-|------|-------------|-----------|---------------|
-| `adr` | Architecture Decision Record | ADR-XXX | proposed, accepted, deprecated, superseded |
-| `flag` | Feature flag / runtime config gate | FLAG-XXX | active, inactive, deprecated |
-| `event` | Domain event | EVT-XXX | active, deprecated |
-| `symbol` | Code symbol (function, class, module) | SYM-XXX | active, deprecated, removed |
+2. **Use briefing for risky work**
+   - Use `/brief-kibi` or `kb_briefing_generate` when task risk/ambiguity is high.
 
----
+3. **Discovery before exact lookup**
+   - Start with `kb_search`.
+   - Follow with `kb_query` for exact entities/filters (`id`, `type`, `sourceFile`, `tags`).
+   - Use `kb_status` when branch/snapshot freshness confidence matters.
+   - Use `kb_find_gaps`, `kb_coverage`, `kb_graph` for curated analysis.
 
-## Relationship Types
+4. **Mutation discipline**
+   - Query before mutate.
+   - Create relationship endpoints before linking.
+   - Run `kb_upsert` sequentially (never parallel).
+   - Use small, reviewable batches.
+   - Use `kb_delete` only for intentional removals with dependency awareness.
 
-| Relationship | Source → Target | Description |
-|--------------|-----------------|-------------|
-| `depends_on` | req → req | Requirement depends on another |
-| `specified_by` | req → scenario | Requirement specified by scenario |
-| `verified_by` | req/scenario → test | Requirement or scenario verified by test |
-| `validates` | test → req/scenario | Test validates requirement or scenario |
-| `implements` | symbol → req | Symbol implements requirement (Ownership) |
-| `covered_by` | symbol → test | Symbol covered by test (Coverage) |
-| `executable_for` | symbol → test | Symbol is executable test code for a test entity (Identity) |
-| `constrained_by` | symbol → adr | Symbol constrained by ADR |
-| `constrains` | req → fact | Requirement constrains domain fact |
-| `requires_property` | req → fact | Requirement requires property/value fact |
-| `guards` | flag → symbol/event/req | Flag guards entity |
-| `publishes` | symbol → event | Symbol publishes event |
-| `consumes` | symbol → event | Symbol consumes event |
-| `supersedes` | adr → adr, req → req | ADR or requirement supersedes prior one |
-| `relates_to` | any → any | Generic relationship |
+5. **Validation discipline**
+   - Run targeted `kb_check` rules during iteration.
+   - Run a final `kb_check` before completion.
 
----
+## Modeling Rules (Current Standard)
 
-## Querying Kibi
+- Canonical traceability chain: `REQ-* -> SCEN-* -> TEST-*`.
+- Prefer typed relationships (`specified_by`, `verified_by`, `validates`, `implements`, `covered_by`, `executable_for`, etc.).
+- Plain string `links` import as generic `relates_to` only.
 
-### MCP Tool Queries (Preferred)
+### Strict fact lane (contradiction-safe requirements)
 
-Agents should use MCP tools for all KB interactions. For initial repository setup, use the `/init-kibi` slash command in OpenCode.
+For normative requirements that should participate in contradiction checks:
+- Link requirement -> `fact_kind: subject` via `constrains`
+- Link requirement -> `fact_kind: property_value` via `requires_property`
 
-Available MCP tools:
-- `kb_query` - Query entities by type, ID, tags, and source file
-- `kb_upsert` - Insert or update entities
-- `kb_delete` - Delete entities by ID
-- `kb_check` - Validate KB integrity
+For bugs/workarounds/governance notes:
+- Use `fact` with `fact_kind: observation` or `meta` (non-blocking lane)
+- Do **not** model bug records as `flag` unless there is an actual runtime/config gate
 
-If the KB needs setup or repair beyond what `/init-kibi` provides, ask the user/operator to handle it outside the agent session.
+Requirement semantic evolution is append-only:
+- Create a new requirement and link old -> new with `supersedes` semantics as appropriate.
 
-### OpenCode Smart-Enforcement Expectations
+## Symbol Traceability Standard
 
-- OpenCode guidance is **posture-aware** and **low-token**. In `vendored_only` or safe docs/test edits, you may see little or no Kibi guidance.
-- The absence of a prompt does **not** mean Kibi rules are disabled. Git hooks and `kb_check`-backed validation remain the hard enforcement layer.
-- Agent-visible guidance stays **MCP-only**: use `kb_search`, `kb_query`, `kb_upsert`, `kb_delete`, `kb_check`, `kb_status`, `kb_find_gaps`, `kb_coverage`, and `kb_graph`.
-- Treat prompt guidance as advisory workflow help; treat hooks/checks as the authoritative boundary.
+- New/modified symbols must be traceable to at least one requirement.
+- Preferred for test/e2e code: symbol manifest + `executable_for` relation.
+- Inline `// implements REQ-xxx` remains optional/backward-compatible for quick code-only changes.
+- When code edits change symbol extraction output, include updated `documentation/symbols.yaml` in the same commit as the related code/documentation changes.
 
----
+## Release & Versioning Rules (npm packages)
 
-## Rules for Agents
+Applies when changing publishable packages (`kibi-core`, `kibi-cli`, `kibi-mcp`, `kibi-opencode`).
 
-### Rule 1: Kibi-First Documentation (VERY IMPORTANT)
+- Add a changeset as part of the same work.
+- Use Conventional Commits.
+- Do not publish manually (`npm publish` forbidden).
+- Run `bun run version-packages` on `develop` (or pre-merge flow targeting develop).
+- Do not merge `master` back into `develop`.
+- After version/wiring changes used by local dogfooding, run `bun run build`.
 
-**All work must be documented using kibi.**
+### Changeset writing rule: human-readable first
 
-When you encounter code that is not obvious about its intent on first sight:
+Every changeset must start with a short human-facing summary before technical bullets:
 
-1. **Query Kibi first** with `kb_query` instead of grepping the project
-2. If `kb_query` returns nothing:
-   - **a)** Do the research yourself (read code, understand context)
-   - **Update kibi** with your findings (create/update entities, relationships)
-   - **b)** If the query mechanism itself is lacking, **report it to the user** so kibi can be improved
+1. **User impact prose first** (2-4 sentences): what changed from a human user's perspective, why it matters, and what behavior/outcome is different.
+2. **Dry technical summary second**: concise commit-style/package-level details.
 
-This ensures the knowledge base grows with each investigation, making future work easier for both humans and agents.
+Do not start a changeset with internal-only jargon or dry commit bullets.
 
-### Rule 2: Git Workflow Rules
+## Test Hygiene (Environmental Pollution)
 
-**Commit your work whenever a deliverable is ready, using industry-standard conventions.**
+Before declaring tests passing:
 
-- **Conventional Commits**: Always use the [Conventional Commits](https://www.conventionalcommits.org/) format (e.g., `feat:`, `fix:`, `docs:`, `refactor:`, `chore:`).
-- **Commit on Ready**: Create a commit as soon as a feature, fix, or documentation update is complete.
-- **Local Only**: Do **not** push your commits. Just perform the local commit.
-- **Kibi Integration**: Commits trigger Kibi's git hooks to automatically sync and validate the knowledge base.
+- Restore mocks in `afterEach`.
+- Isolate filesystem side effects and clean up temp artifacts.
+- Reset mutable module/global state between tests.
+- Verify both isolated test runs and full-suite runs.

-### Rule 3: Release Metadata and Versioning (npm Packages)
-
-If you change any publishable npm package (`kibi-core`, `kibi-cli`, `kibi-mcp`, `kibi-opencode`), you MUST manage release metadata using [changesets](https://github.com/changesets/changesets).
-
-- **Create Changesets Immediately**: Add a changeset as part of your work, not as an afterthought. Use `bun run changeset` on your branch.
-- **Bump Versions on Develop**: If your work includes version bumps, run `bun run version-packages` on `develop` (or your feature branch before merge to `develop`). All version bumps must be committed before merging to `master`.
-- **Semver Discipline**:
-  - **Patch**: Bug fixes, documentation, minor internal refactors.
-  - **Minor**: New features, non-breaking CLI/API additions.
-  - **Major**: Breaking changes to CLI, MCP tools, or core Prolog schema.
-- **Do NOT Publish Directly**: Manual `npm publish` is forbidden. Publishing occurs automatically on `master` CI after `develop` is merged.
-- **Dogfood Rebuild Rule**: This repo uses local `kibi-mcp` and `kibi-opencode` artifacts. After changing versions or local wiring, run `bun run build` to ensure your OpenCode environment reflects the changes.
-- **No Back-Merge**: Do not merge `master` back into `develop`.
-
----
-
-### 1. Interactive Bootstrap Onboarding (Day-0)
-Always use the `/init-kibi` workflow for initial repository activation. This is an interactive process:
-- **Gather Context**: Ask the user at most 4 bounded questions (summary, source of truth, priority root, config anchors).
-- **Synthesize**: Use `kb_autopilot_generate` for read-only candidate synthesis grounded in declared context and codebase evidence.
-- **Preview and Approve**: Present a preview of the proposed plan and candidates. Do NOT proceed to writes without explicit user approval.
-- **Apply and Validate**: Apply approved candidates sequentially via `kb_upsert` and run `kb_check` to verify integrity.
-
-### 2. Start-task Briefing
-Use `kb_briefing_generate` or `/brief-kibi` when you need a citation-backed briefing before risky work.
-
-## Kibi MCP Best Practices
-
-### Query First
-Always call kb_query before mutations to confirm current state.
-
-*Rationale:* Prevents duplicate entities and ensures you're updating existing records rather than creating conflicts.
-
-### Create Before Link
-Relationship endpoints must exist before creating the relationship.
-
-*Rationale:* Referential integrity requires target entities to be defined; otherwise, the relationship will fail validation.
-
-### Prefer Targeted Checks
-Use kb_check with explicit rules during iteration, not the full check.
-
-*Rationale:* Targeted checks are faster and provide focused feedback, speeding up the iteration cycle.
-
-### Sequential Writes
-Issue kb_upsert calls sequentially, never in parallel (avoid mutex contention).
-
-*Rationale:* Kibi uses file-based storage with mutex locks; parallel writes can cause contention errors and data corruption.
-
-### Tags Are Not IDs
-The tags parameter filters by metadata tags, not entity IDs.
-
-*Rationale:* Tags are categorization labels, not identifiers; filtering by ID requires the id parameter, not tags.
-
-### Small Batches
-Upsert in small reviewable batches, validate after each.
-
-*Rationale:* Smaller batches make errors easier to isolate and recover from, and ensure each batch is correct before moving on.
-
-### Gap Reports
-Record uncertainty in gap reports, not speculative entities.
-
-*Rationale:* The KB should contain verified knowledge, not guesses; speculative entries introduce noise and reduce trust in the system.
-
-### Strict Fact Modeling for Normative Requirements
-Use the strict fact lane when a requirement should participate in contradiction blocking: link the req to a `fact_kind=subject` fact via `constrains` and to a `fact_kind=property_value` fact via `requires_property`. Use `observation` and `meta` for non-blocking evidence and governance notes.
-
-### Prefer Append-Only Requirement Evolution
-When requirement semantics change, create a new requirement and link the old one with `supersedes` rather than assuming a plain upsert replaces earlier strict-fact semantics.
-
-### Entity Choice for Bug and Workaround Documentation
-
-When documenting bugs, incidents, or workarounds:
-  - Create a `fact` entity with `fact_kind: observation` or `fact_kind: meta`
-  - Do NOT create a `flag` entity unless there is an actual runtime/config gate
-  - Use `relates_to` to link the fact to related requirements, tests, or ADRs
-
-When a bug is temporarily mitigated by a feature gate:
-  - Create TWO records: `fact` (describes the issue/workaround) + `flag` (the gate)
-  - Link them with `relates_to` since no typed relationship exists for this case
-
-**Canonical mapping:**
-  - `flag` = runtime/config gate (includes kill-switches, deferred capabilities)
-  - `fact` (observation/meta) = bug records, incident notes, workarounds
-  - `req` = intended/corrected behavior (Owner)
-  - `scenario` = canonical behavior specification
-  - `test` = executable verification (Identity)
-  - `adr` = durable design rationale
-
----
-
-## Documentation Workflow
-
-### Creating a New Entity
-
-1. Create a Markdown file in the appropriate directory (canonical location under documentation/):
-   - Requirements: `documentation/requirements/REQ-XXX.md`
-   - Scenarios: `documentation/scenarios/SCEN-XXX.md`
-   - Tests: `documentation/tests/TEST-XXX.md`
-   - ADRs: `documentation/adr/ADR-XXX.md`
-   - Flags: `documentation/flags/FLAG-XXX.md`
-   - Events: `documentation/events/EVT-XXX.md`
-   - Facts: `documentation/facts/FACT-XXX.md`
-
-> **Entity Choice Decision**: Use `flag` only for actual runtime gates. For bug/workaround documentation, use `fact` with `fact_kind: observation` or `meta` instead.
-
-2. Include frontmatter with required fields:
-   ```yaml
-   ---
-   id: REQ-XXX
-   title: Short summary
-   status: open
-   created_at: 2026-02-20T10:00:00Z
-   updated_at: 2026-02-20T10:00:00Z
-   source: path/to/source
-   tags:
-     - relevant-tag
-   ---
-   ```
-
-3. The entity will be synced to the KB by git hooks or operator-initiated sync.
-
-### Updating an Entity
-
-1. Edit the Markdown file
-2. Update `updated_at` timestamp
-3. The changes will be synced by git hooks or operator-initiated sync.
-
-### Linking Entities
-
-Use the `links` field in frontmatter to declare relationships:
-```yaml
-links:
-  - REQ-001  # This entity relates to REQ-001
-  - ADR-005  # This entity relates to ADR-005
-```
-
-Plain string `links` import as generic `relates_to` edges only. When contradiction-safe semantics matter, prefer typed links such as:
-
-```yaml
-links:
-  - type: constrains
-    target: FACT-SESSION
-  - type: requires_property
-    target: FACT-SESSION-MAX-AGE-30-MINUTES
-```

-## Quick Reference for Agents
-
-### MCP Tools
-
-```text
-kb_query(type, id, tags, sourceFile, limit, offset)
-kb_upsert(type, id, properties, relationships)
-kb_delete(ids)
-kb_check(rules)
-```
-
-### Slash Commands (OpenCode)
-
-- `/init-kibi` - Bootstrap Kibi in the current repository
-
-### Setup/Repair Escalation
-
-If the KB needs initialization, repair, or configuration beyond `/init-kibi`:
-1. Ask the user/operator to run the appropriate CLI commands
-2. Do not attempt to run `kibi` CLI commands yourself
-
-### Entity Choice Quick Reference
-
-- `flag` — Runtime/config gate (NOT for bug records)
-- `fact` — Domain facts; use `observation`/`meta` for bugs/workarounds
-- `req` — Intended behavior
-- `test` — Executable verification
-- `adr` — Durable design decisions
-
-**Rule**: Bug mitigated by a gate? Create both: `fact` (issue) + `flag` (gate).
-
----
-
-## Notes
-
-- `.kb/` is repo-local and per-branch
-- KBs are copied from `main` on new branch creation
-- Git hooks automate KB sync on branch checkout/merge
-- If you encounter KB setup issues, ask the user/operator to run the appropriate Kibi diagnostics outside the agent session
-

-## Staged Symbol Traceability (Agent Workflow)
-
-Staged Symbol Traceability ensures that every new or modified code symbol (function, class, or module) is explicitly linked to at least one requirement before it can be committed. This is a powerful feature for agents to enforce traceability.
-
-### Purpose
-
-This feature enforces a discipline where every code change must reference a requirement (REQ-xxx). It prevents "orphan" code from being merged, ensuring that all new features, bug fixes, and refactors are traceable to a documented need. This is especially valuable for regulated projects, safety-critical systems, or any team that wants to avoid technical debt and improve auditability.
-
-### Agent Workflow
-
-When implementing code changes, an agent should:
-
-1. **Prefer relationship-based traceability for test and e2e code:**
-   Instead of inline comments, model the code as a symbol (e.g., in `documentation/symbols.yaml`), link it to a `TEST-*` entity with `executable_for` to establish its identity. The canonical traceability chain is `REQ-xxx` → `SCEN-xxx` → `TEST-xxx`. Use `covered_by` to link symbols to the tests that exercise them.
-
-2. **Add the `implements REQ-xxx` directive (Optional/Backward-Compatible):**
-   Inline comments remain supported and are useful for quick code-only changes:
-   ```typescript
-   export function myFunc() { } // implements REQ-001
-   ```
-
-   You can link to multiple requirements:
-   ```typescript
-   export class MyClass() { } // implements REQ-001, REQ-002
-   ```
-
-
-### Configuration
-
-> **Note:** The `.kibi/traceability.json` configuration file is not yet implemented. Traceability enforcement is handled automatically by git hooks.
-
-The following schema is planned for a future release:
-
-```json
-{
-  "minLinks": 1,
-  "langs": ["ts", "tsx", "js", "jsx"]
-}
-```

-## Test Environmental Pollution Prevention
-
-Tests must be checked for environmental pollution - only a full suite run can be treated as a pass.
-
-**What is environmental pollution?**
-When a test modifies global/module-level state that persists and breaks subsequent tests. Examples:
-  - Mocking `node:fs` globally without restoring it
-  - Mutating shared module state across tests
-  - Not cleaning up after tests that modify process state
-
-**Required practices:**
-  1. **Always restore mocks in afterEach** - Call `mock.restore()` or reset mocked modules
-  2. **Isolate filesystem operations** - Use temporary directories and clean them up
-  3. **Reset module state** - If a module has mutable state, export a reset function and call it in beforeEach
-  4. **Test in isolation first** - Verify tests pass individually before claiming they pass
-  5. **Run full suite** - Always verify tests pass when run with the full test suite, not just in isolation
-
-**Common pitfalls:**
-  - Using `mock.module()` without calling `mock.restore()` - pollutes subsequent tests
-  - Module-level caches that persist across tests
-  - Global variable modifications without cleanup
-
-**Verification:**
-  Before marking a test as passing, verify it passes in BOTH isolation AND as part of the full suite run:
-  ```bash
-  # Test in isolation (passes)
-  bun test path/to/specific.test.ts
-
-  # Test in full suite (must also pass)
-  bun test
-  ```

+OpenCode bootstrap command support is now more reliable in fresh CI and Bun installations. The plugin can detect native `/init-kibi` command support when OpenCode installs the SDK as a transitive dependency of the plugin, preventing supported hosts from silently falling back to the namespaced MCP prompt.
+
+- Resolve `@opencode-ai/sdk` metadata from Bun's plugin-sibling dependency layout during native command capability detection.
+- Add regression coverage for the transitive SDK resolution path used by fresh installs.

 - Adds `.kb/` and `.kb/briefs/` to `.gitignore`
 - Creates default `config.json` with document path patterns
+- Creates `documentation/symbols.yaml` when it does not already exist
 
 **Flags:**
 - `--no-hooks` - Skip git hook installation (hooks are installed by default)
 
 **Notes:**
 - Hooks are installed by default. Only use `--no-hooks` if you specifically don't want automated syncing.
+- The pre-commit hook blocks commits when `documentation/symbols.yaml` has unstaged changes, forcing refreshed symbol coordinates to be staged with the related code changes.
 - Idempotent: safe to run multiple times
 - After running, see the quick start guide in README.md for next steps

+Kibi now makes symbol manifest tracking harder to forget. New projects initialized with `kibi init` get a default `documentation/symbols.yaml`, and the managed pre-commit hook blocks commits when that manifest has unstaged changes so refreshed coordinates are committed with the related work.

+- Create the default symbol manifest during `kibi init` when it is missing.
+- Add a pre-commit guard that requires dirty `documentation/symbols.yaml` changes to be staged before `kibi check --staged` runs.
