fix(e2e): resolve the measurement evidence path instead of hardcoding it (#549) - #553
Merged

Conversation
… it (#549) Both measurement specs hardcoded the PRE-ARCHIVE change directory: const EVIDENCE_PATH = "openspec/changes/verify-subagent-pull-under-load/measurements.json"; and `record()` opened it with `mkdirSync(dirname(EVIDENCE_PATH), { recursive: true })`. Once the change was archived (#548) that combination CREATED the pre-archive directory rather than failing, with two consequences: 1. A phantom active-change directory reappeared on every re-measure — tooling that enumerates `openspec/changes/*` sees an active change that is really a leftover of an archived one. 2. Worse for evidence integrity: the write silently landed somewhere OTHER than the archived `heap-evidence.md`'s source of truth, so a re-run looked like it left the archived numbers unchanged while actually recording different ones elsewhere. That happened during #548 — the final post-fix run's numbers went to the stray path and were never transcribed. Exactly the staleness the evidence file exists to prevent. New `tests/e2e/helpers/evidence-path.ts`: - `resolveEvidencePath(name, root?)` prefers the active `openspec/changes/<name>/`, falls back to the NEWEST `openspec/changes/archive/<YYYY-MM-DD>-<name>/`, and THROWS when the change is in neither place. It never creates a directory — a misdirected write must be loud, not silent. - The archive matcher is anchored at both ends, so `verify-x` cannot match `verify-x-followup`, and a non-directory entry that matches the name pattern is ignored. - Repo root is derived from the module's own URL, not cwd, since specs run from varying working directories. - `recordMeasurement()` absorbs the byte-identical `record()` that both specs carried, so the path rule has ONE home. Coverage: `tests/` was collected by no vitest project, and both consuming specs are opt-in (`PI_SYNTH_AGENT_TICKS=1`), so this logic could never run in CI. Adds a deliberately narrow `tests` project whose include glob is `e2e/helpers/__tests__/` only — Playwright specs still belong to `npm run test:e2e`, which needs a docker harness and a browser. 10 unit tests cover active-dir preference, the newest-archive pick for a change archived twice, prefix-collision rejection, a matching non-directory, and the fail-loud path (including that no directory appears as a side effect of the failure). Verified non-vacuous: restoring the old create-anyway behaviour turns 6 of the 10 red. Closes #549

Apply the docs authoring rule to both changed records.
Both records use long compound prose. Rewrite them as short declarative fragments and route both writes through DocScribe.

vitest.config.tsindex entry as short factual fragments. - docs/vitest.config.ts.AGENTS.md#L3-L3: Rewrite the companion purpose record as short factual fragments.
As per coding guidelines, every write under docs/ must be delegated to DocScribe and use caveman style: short declarative fragments, concrete tokens, and one fact per line.

Fixed in 0cc2ce2. Valid — the earlier pass did route through DocScribe, but what came back was compound prose, so the rule was followed in process and missed in output.
Both records rewritten through DocScribe: one fact per line, no sentence chaining, concrete tokens. Every fact retained (Vitest 4 / test.projects / new tests project / tests/e2e/helpers/__tests__/ only / Playwright exclusion + npm run test:e2e / the opt-in-spec rationale / See issue #549).
One constraint applied that is not obvious from the guideline: no backticked glob tokens. kb dox lint resolves backticked path-like tokens as real paths, so **/*.test.ts is reported as broken-ref. Both records cite the real directory instead. Lint is clean on both files.
#549) Three CodeRabbit findings on PR #553, all valid. 1. (Major) `recordMeasurement()` wrapped BOTH `readFileSync` and `JSON.parse` in one blanket `catch`, so an unreadable or half-written `measurements.json` was silently replaced by an object holding only the newest key — every measurement recorded before it dropped without a word. That is the same silent-evidence-loss failure this module exists to prevent, just one layer in. Extracted `readEvidence(path)`: ENOENT yields `{}` (genuine first write), every other read error is rethrown, a parse failure throws naming the file, and a parsed array/primitive/null is rejected instead of being cast to `Record` and mutated. A damaged evidence file now stops the run rather than being overwritten by it. 2. (Minor) `changeName` was joined into a path unvalidated. `join(changesDir, "../..")` resolves to the repo root — a real directory — so a traversal name resolved successfully and would have written `measurements.json` outside `openspec/` entirely. `assertSingleComponent()` now rejects empty, `.`, `..`, and any name containing `/` or `\`. 3. (Minor) Both `docs/` records were compound prose, violating the repo's caveman-style rule. Rewritten through DocScribe: one fact per line, no sentence chaining. No backticked glob tokens, since `kb dox lint` resolves those as real paths and reports broken-ref. Tests 10 → 25. New cases: five traversal/separator forms rejected, a traversal name proven not to resolve to the repo root, existing keys read back, malformed JSON left ON DISK rather than clobbered, four non-object JSON shapes rejected, and a non-ENOENT read error (mode 000) rethrown rather than swallowed. Both fixes verified non-vacuous: commenting out the guard turns 4 red; restoring the blanket catch turns the rethrow case red.

CodeRabbit follow-up on PR #553. `current[key] = value` with key `"__proto__"` mutates the object's prototype instead of adding a property, so that measurement never reaches the JSON — a recorded number silently absent from the evidence file, which is the failure class this module exists to prevent. `Object.defineProperty` with an enumerable descriptor records every key as an own property. `recordMeasurement()` gains an optional `repoRoot` (defaulting to `REPO_ROOT`, matching the other exports) so the behaviour is assertable against a temp fixture instead of the real tree. Five regression tests assert through the ROUND TRIP TO DISK — reading the file back and checking `Object.hasOwn` — rather than inspecting the in-memory object, which would pass on the broken code. Reachability, stated plainly: every `key` at both call sites is a string literal (`"F1"`, `"P1-harness-ceiling"`, ...), so this was not reachable. Fixed because the descriptor costs one line, not because it was exploitable. Non-vacuity: restoring `current[key] = value` turns the two `__proto__` cases red. The `constructor`/`prototype`/`toString` cases pass either way — plain assignment creates own properties that shadow the prototype — and are kept as boundary documentation, not as teeth.
Commit d4e9952 swept `openspec/changes/archive/2026-08-24-verify-subagent- pull-under-load/measurements.json` into the diff, replacing the real recorded measurements (X1, F1, P1-P5) with test fixtures. Cause, and it is worth naming precisely: the new reserved-key tests called `recordMeasurement(CHANGE, key, value, root)` BEFORE `recordMeasurement` had a `repoRoot` parameter. The fourth argument was silently ignored, the helper fell back to `REPO_ROOT`, and the red test run wrote fixture data into the real archived evidence file. `git add -A` then committed it. That is precisely the failure this change exists to prevent — a measurement write landing in the authoritative evidence file unnoticed — reproduced by the test suite meant to prevent it. Restored from origin/develop. The parameter now exists, and every test passes its temp `root` explicitly, so the suite writes only inside its fixture dir.
Picks up bc45afa (regenerated pnpm-lock.yaml), without which `pnpm install --frozen-lockfile` — ci.yml's first step — fails for every PR built against develop.

Closes #549.
The bug
Both measurement specs hardcoded the pre-archive change directory:
and
record()opened it withmkdirSync(dirname(EVIDENCE_PATH), { recursive: true }). Once the change was archived in #548, that combination created the pre-archive directory instead of failing:heap-evidence.md's source of truth. A re-run therefore looked like it left the archived numbers unchanged while recording different ones elsewhere. That is exactly the staleness the evidence file exists to prevent, and it already happened once during test(verify-subagent-pull-under-load): verify the four scenarios the payload change shipped unverified #548.Fix

tests/was collected by no vitest project, and both consuming specs are opt-in (PI_SYNTH_AGENT_TICKS=1) — so this logic could never execute in CI. This repo's own config comments say it best: "a gate no CI job runs is not a gate."The new

Non-vacuity verified: restoring the old create-anyway behaviour turns 6 of the 10 red; all 10 pass on the fix.
