Each case = a per-language `base/` repo + an `overlay/` +(post-change files only) + `manifest.json` + generated `change.diff` + +`expected-verdict.json`. Working tree = base overlaid with overlay; diff = +`git diff(base → tree)`. Lean (no full-tree duplication) and the diffs are generated, +not hand-counted. + +- **Cases:** TS full set — honest, lying, partial, undeclared, allowlisted, + outcome-fail, behavioral. Python + Go — honest, lying, undeclared (the core trio + proving language-agnostic structural verification + the undeclared moat). 13 cases. +- **Conventions** (documented in `corpus/README.md`): the WU5/WU9 harness asserts the + **stable projection** of the verdict — `result`, `exit_code`, `summary`, each claim's + `id`+`status` (and reason-present for failed/unverifiable), and `undeclared_changes` + fields — but NOT `evidence` or exact `reason` text (non-deterministic). So + `expected-verdict.json` omits evidence. Allowlisted changes are listed with + `severity: "suppressed"` and excluded from `summary.undeclared`. The behavioral case + expects `unverifiable` + **`pass`/exit 0** (unverifiable is an allowed status, §6.6). +- **Tooling:** `tools/generate-diffs.sh` (forces `a/ b/` prefixes regardless of the + user's `diff.mnemonicPrefix`), `tools/build-tree.sh`, `tools/validate.mjs`. +- **Verified now:** all 13 manifests + 13 verdicts validate against `@attest/schema` + (`node corpus/tools/validate.mjs`); every case's `change.diff` applied to `base` + reproduces the build-tree output (triangle consistency); prettier clean repo-wide. +- Added `.prettierignore` so fixture `base/`/`overlay/` trees, `.diff`, and tool + `.sh` files are never reformatted (reformatting a fixture would silently invalidate + its diff) — `pnpm format:check` now passes with the corpus present. + +**Note:** expected verdicts are the oracle's source of truth, authored from the spec +ahead of the engine. When WU5 lands, the engine must conform to them (a change that +breaks an oracle case is wrong by definition); minor reason/evidence shapes may be +tuned, but statuses/exit codes/undeclared sets are fixed. + +**Coverage gap (intentional):** Py/Go partial, allowlisted, outcome-fail, behavioral +cells are unfilled — well-bounded routine follow-on (copy the TS pattern). + +**Next:** WU3 — `@attest/diff` (extract unified-diff parsing into its own package). + +## WU3 — `@attest/diff` unified-diff parser (2026-06-05) + +New package `packages/diff` (SPEC §5, §6.2/§6.3). **Self-contained parser — no +third-party diff lib** (v0.1 used `parse-diff`); the verification path must be +deterministic and fully ours, and the corpus is the oracle for the model. + +- **Model** (`types.ts`): `ParsedDiff → FileDiff[]`; each `FileDiff` has `op` + (`create`/`modify`/`delete`, named to match the manifest `file_change.op` so the + verifier compares without translation), `path`/`oldPath`/`newPath`, `binary`, and + `Hunk[]`.

What attest does NOT do (read this) + +- **No semantic claims.** "Authentication is enforced on every path," "input + is validated," "no SQL injection" are _semantic_ — they require understanding + what the code _means_. attest refuses to answer these with a heuristic. A + semantic claim (`kind: "behavior_present"`, or any unknown `kind`) is + reported as `unverifiable` with an LLM-review pointer — **never a pass and + never a fail**. Route those to a reviewer tool (CodeRabbit, Greptile, human + review). +- **No LLM in the verification path.** Determinism is the product. If a + heuristic starts deciding correctness, attest has stopped being attest. +- **No "agent said it, so it must be true."** Every claim is checked. If a + claim is false, the verdict is `fail` (exit 1). If a file was changed but + not declared, the verdict is `fail` (scope drift). +- **No `description` field on a claim.** If the agent wants to _explain_ a + claim, it goes in the human-facing manifest comment, not in the JSON. The + verifier ignores `description` on claims (allowed, not validated). + +## 4. Minimal example (TypeScript) + +```json +{ + "attest_version": "1.0", + "task": { "id": "add-login", "description": "Add login() to auth" }, + "agent": { "id": "claude-code", "model": "claude-opus-4-8", "tool_calls": 4 }, + "generated_at": "2026-06-06T12:00:00Z", + "declared_scope": { "files": ["src/auth.ts", "tests/auth.test.ts"] }, + "claims": [ + { "id": "c1", "kind": "file_change", "op": "modify", "path": "src/auth.ts" }, + { + "id": "c2", + "kind": "symbol_added", + "path": "src/auth.ts", + "symbol": "login", + "symbol_kind": "function" + }, + { "id": "c3", "kind": "test_added", "path": "tests/auth.test.ts", "covers": "login" }, + { "id": "c4", "kind": "outcome", "check": "tests_pass" } + ] +} +``` + +## 5. The `declared_scope` rule + +`declared_scope.files` must equal the union of all `path` values from every +claim, **plus** any file the agent touched that isn't named in a claim (so +attest can flag it as undeclared). In practice: list every file the agent +edited, full stop. A missing entry causes `undeclared_changes` and exit 1. +An extra entry is ignored. + +## 6. The exit code contract + +| Exit | Meaning | +| ---- | ------------------------------------------------------------------------------------------------------------------------------ | +| `0` | Every claim is `verified` or `unverifiable`; zero flagged undeclared. | +| `1` | At least one claim is `failed`, or at least one undeclared change is flagged. | +| `2` | The manifest is structurally invalid (wrong `kind`, missing field, wrong `attest_version`, etc.).

It is +the verifier's way of saying "this is outside my scope, route it to a +reviewer." The agent or human adds `covers`, `test_*`, or `outcome` claims +themselves; the verifier never invents them. + +## 7. Drift failures you'll see in CI + +If the manifest is malformed, the CLI prints one path-pointed line per issue +and exits 2. Common ones: + +- `attest_version: must be exactly "1.0" (the only supported manifest version)` +- `claims/0/op: must be one of "create", "modify", "delete" (file_change claims need a known operation)` +- `claims/0/id: must match the pattern ^c[0-9]+$ (e.g. "c1", "c2", "c10") — claim ids are stable identifiers used by humans and CI logs` +- `claims/0/check: must be one of "build_passes", "tests_pass", "lint_passes" (outcome claims declare which check was run; build/tests/lint are the supported v1.0 set)` +- `manifest: unknown top-level field "..." — the v1.0 manifest has a closed top-level shape (attest_version, task, agent, generated_at, declared_scope, claims)` + +## 8. How the agent should produce one + +1. Run `attest init --diff ` (or omit `--diff` to use + `git diff HEAD` against `--repo-root`). The CLI emits a JSON skeleton with + `declared_scope.files` and a `file_change` claim per touched file, plus + `symbol_added/removed/modified` stubs derived from tree-sitter extraction + on the post-change file. No LLM involved. +2. The agent (or human) fills in `outcome` claims and any `covers` strings + the skeleton didn't auto-generate. +3. The user runs `attest verify --manifest .attest/manifest.json --diff --repo-root .`. + +The skeleton is deterministic — same diff, same skeleton, every time. Two +agents working off the same diff produce the same starting manifest. diff --git a/eslint.config.mjs b/eslint.config.mjs index 18feff5..cd6c8d7 100644 --- a/eslint.config.mjs +++ b/eslint.config.mjs @@ -3,7 +3,7 @@ import tseslint from "typescript-eslint"; export default tseslint.config( { - ignores: ["**/dist/**", "**/node_modules/**", "**/*.js", "**/*.mjs", "**/*.cjs"], + ignores: ["**/dist/**", "**/node_modules/**", "corpus/**", "**/*.js", "**/*.mjs", "**/*.cjs"], }, { files: ["packages/*/src/**/*.ts", "packages/*/test/**/*.ts"], diff --git a/packages/cli/package.json b/packages/cli/package.json index c11e56f..02593eb 100644 --- a/packages/cli/package.json +++ b/packages/cli/package.json @@ -1,26 +1,56 @@ { "name": "@attest/cli", - "version": "0.1.0", + "version": "1.0.0", "type": "module", + "description": "Deterministic, locally-runnable verifier for AI-agent change manifests.
