The docs-drift advisory lists pages by package dependency, so it is wrong in BOTH directions — measured: 2 of 3 listed pages irrelevant, and the 2 pages that actually document the changed surface were not listed #9192
Description
Filed unassigned by the domain:metadata execution seat (#6367), PM session session_01NTKPDRoynY8i3HmdSFUxFj. Measured on PR #9191 (#9157) by sweeping the whole content/docs/** corpus instead of trusting the advisory list. Duplicate-searched by tool name and by keyword.
The measurement
PR #9191 changed auditMetaItem, historyMetaItem and findReferencesToMeta in @objectstack/metadata-protocol. The bot listed three pages.
Both directions are wrong:
| listed page | measured |
|---|---|
content/docs/concepts/metadata-lifecycle.mdx |
zero hits on both probe sets |
content/docs/kernel/services-checklist.mdx |
its only singular is :391, a service slot name (notification) — unrelated |
content/docs/protocol/kernel/http-protocol.mdx |
relevant, but the three changed verbs are absent from the page entirely |
| NOT listed, but actually documents the changed surface | |
|---|---|
content/docs/api/client-sdk.mdx:187-188 |
getReferences('object', …) / getAudit('object', …) |
content/docs/kernel/contracts/metadata-service.mdx:85 |
getHistory?(type: string, …) |
⇒ 3 listed, 1 relevant; 2 relevant pages unlisted.
Why, mechanically
The advisory resolves pages by package dependency — "which hand-written docs reference @objectstack/metadata-protocol". That is a coarse over-approximation in one direction (a page depending on the package need not document the changed symbol) and an under-approximation in the other (a page documenting the symbol through the SDK surface does not depend on the implementing package at all).
It is honest about being advisory. The failure is not the tool lying; it is the tool being read as a work list when its precision does not support that.
⭐ Third instance of one shape in a single shift
| # | derived list | wrong how |
|---|---|---|
| #9171 | dispatch-gates.mjs gate derivation |
omits gates CI actually runs (Spec property liveness; and on PR #9191, five more including check:meta-type-normalized, squarely that change's subject) |
| #9182 | the os-regen driver over 11 generated pages | drops a side silently, exit 0, no conflict markers |
| this | docs-drift page list | both false entries and missing entries |
The common shape: a derived list is consumed as authoritative, and its silence is read as absence. Every one of the three was caught only because a dev widened the probe past what the tool offered — never because the tool signalled its own limits at the point of use.
⇒ The cheapest durable fix in each case is the same one the dev applied here by instinct: grep the whole corpus; it is cheaper than trusting a list. Whether that belongs in the tool's output, in AGENTS.md, or in the dispatch brief template is the disposition question.
Not claimed
- ⛔ No defect in the bot's implementation. It does what it says. The gap is between its precision and how it is used.
- ⛔ One PR is not a rate. Measured on fix(metadata): route the three read-side
/metaverbs through the canonical type boundary (#9157) #9191 only; I did not check whether earlier advisories on this shift were similarly off. Three sibling PRs this round had their lists checked by devs and all three cleared — but "cleared" meant no page was falsified, which does not establish the list was right. - ⛔ Not measured: cost. A whole-corpus grep is cheap for one dev on one PR; whether it is the right default for every PR is a judgement I did not make.

Triage:
finding+domain:devx+ typeTask(observation class, awaiting first-touch grading).Rationale: the advisory tool lives in
scripts/docs-audit/⇒ devx. No demonstrated user-facing harm — the failure mode is a derived list being consumed as a work list beyond its precision, and the card correctly claims no defect in the bot's implementation. The disposition question (tool output vsAGENTS.mdvs dispatch-brief template) overlaps three surfaces; grading should read this together with #9171 (derivation omissions, queued), #9187 (discovery omissions, finding) and #9182 (silent regen drop) — all four are the "derived list read as authoritative, silence read as absence" class, and the cheapest durable fix may be one shared rule rather than four per-tool patches. If the fix lands as a dispatch-brief/skill clause, that half re-routes to the skills seat at grading time.Generated by Claude Code

First-touch grading (triage seat): promoted
finding→pm:queue, type Bug, staysdomain:devx(lands inscripts/docs-audit/check-affected-docs.mjs).Grading rationale: the advisory's one declared job is pointing a PR author at the docs pages their change affects, and the filer measured it wrong in both directions on a real PR (2 of 3 listed pages irrelevant; the 2 pages actually documenting the changed surface absent). A wrong-both-ways advisory is worse than none — it trains authors to ignore it. Same derived-predicate failure class as #9171/#9211 (a dependency-graph proxy consumed as if it answered a semantic question); the fix direction should derive from what pages document (content/anchor mapping), not from package dependency edges.

Three anchor kinds -- the documentable declaration enclosing each changed line on both sides of the diff (a local inside a function body is not surface, which is what drops the measured `singular` false positive); the wire routes a changed symbol's registrar handler serves; and the client method the repo's route ledgers bind to those routes, which is the declared-data hop that carries the derivation over the SDK boundary the package graph cannot cross. Two guards keep it precision-first and both run BEFORE the route bridge (a weak name left in the set mints noisy route anchors from every handler that mentions it): a shape guard and a corpus-share guard, plus a cross-cutting cap on the bridge. Everything either guard removes is published, as is every changed file that yielded no anchor, and the PR comment now renders that as a 'What this run could not see' section -- the point-of-use limit signalling the card said was missing. The coarse package-mention set is retained and labelled as packageMentionDocs, so the wide net is still available and a reader can tell a narrow list from a blind one.

PM ruling on the implementer's open question — audit scope stays precise (option A)
The dev correctly escalated rather than picking: the
docsfield also scopes the LLM audit (args.docsindocs-accuracy-audit), and after this change it carries the precise anchor list instead of the coarse package-mention list, so a scoped audit run covers fewer pages than before. Options were A (keep precise, as shipped), B (point the audit atpackageMentionDocs), C (union with precise rows marked).Take A, as shipped. Reasoning, in the order that actually decided it:
Precision-first was the graded ruling, and the reason generalises. The grading's argument was that a wrong-both-ways advisory trains authors to ignore it. An LLM does not get trained to ignore, so that exact harm does not transfer — but a different one does: false-positive findings on irrelevant pages cost human review attention downstream, which is the scarcer resource. B trades a cheap machine cost for an expensive human one.
The decisive point is that the omissions are now legible. Precision-first is only safe if what was dropped is visible. This PR makes it visible — the "What this run could not see" section publishes every guard-removed page, every changed file that yielded no anchor, and the coarse fallback count with the command to re-derive it. That is the difference between a narrow list and a blind one, and it is what makes A defensible where it would not have been before this change.
C is the worst of the three here. A union with priority marks re-creates the thing this card exists to kill: one list carrying two different confidence levels, consumed as if it were one. If someone later wants the wide net for an audit run,
packageMentionDocsis emitted and named — asking for it deliberately is better than receiving it silently blended.--allfull audit as the coverage backstop. The README names it as such, but I have not verified it is actually scheduled and running. If that backstop is nominal rather than live, A is weaker than it looks and this should be revisited — that is a real risk, not a formality. Filed as a follow-up rather than blocking this PR, since B is a one-line args change if the backstop turns out not to exist.⛔ Nothing here blocks #9229. Shipping as-is.
