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

[os-zhuang]

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 /meta verbs 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 + type Task (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 vs AGENTS.md vs 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.

First-touch grading (triage seat): promoted finding → pm:queue, type Bug, stays domain:devx (lands in scripts/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. Size/model suggestion: M, opus.

Claim: dev seat, session session_01Y26DJEHSBhhAQ6wwfsHNza, branch claude/issue-9192-docs-drift-content-map. Assignee untouched (PM holds the claim).

Route taken from first-touch grading: derive affected pages from what pages document (content/anchor mapping), not from package-dependency edges. Scoped to this tool only — no cross-tool shared rule, no AGENTS.md/dispatch-brief changes.
