[finding] Catalog anatomy drift: hand-authored per-topic files live under `references/` (reserved for generated pointers) in objectstack-platform and objectstack-data, unlinked or linked only by path — PLAT-G-02 / the `data-hooks.md` shape, catalog-wide

[os-litant]

Recorded by the skills lane seat (session session_01LraLgQVGq8egUwfYZpbYt1) from the optimization program's per-package audits (program anchor #14292): the platform audit's PLAT-G-02 (deferred on #14299 as "the catalog follow-up" in the seat's ACCEPT on PR #14351) and the same shape measured on objectstack-data in the data flight (references/data-hooks.md, now the canonical hooks anchor after rules/hooks.md was deleted in PR #14427). Filed so that #14299 can close on its last in-scope item; the placement question is catalog-wide and belongs to one pass, not to a per-package flight.

What

skills/README.md (the catalog anatomy, generator-owned) reserves references/ for the generated _index.md ("generated pointers … do not hand-edit") and assigns hand-authored per-topic files to rules/ ("(optional) detailed per-topic rule files linked from SKILL.md"). Two packages violate that on origin/main today:

package	file	measured
objectstack-platform	references/plugin-hooks.md	hand-authored; 2,413 tokens after PR #14351; the platform flight linked it directly from SKILL.md (the "two hops" finding), but its location still contradicts the anatomy
objectstack-data	references/data-hooks.md	hand-authored; the canonical hooks anchor since PR #14427 deleted rules/hooks.md; objectstack-ui, objectstack-automation and objectstack-platform now point at it by path

Both are load-bearing anchors that other packages cite by path (references/data-hooks.md from ui/automation/platform; references/plugin-hooks.md from data's References block), so a move is a multi-package rename with pointer updates, a check:skill-identifier-liveness Leg-2 binding check (bindings are keyed by file path + heading) and ceiling-row renames in scripts/check-skills-token-ratchet.mjs — one pass, after the in-flight splits (#14298, #14300 r2, #14297 r2) land, so the rows do not race.

Two honest resolutions, both need a lane decision, not a dev's guess

1. Move both files to rules/ and update every cross-package pointer in one PR (governed skills/**, draft, human merge) — the anatomy stays as written.
2. Amend the anatomy (the generator's source for skills/README.md) so references/ may also hold hand-authored reference material that is linked from SKILL.md, and require the link — the files stay where three packages already point.

Option 2 is cheaper and matches what the flights converged on (both files are now linked directly); option 1 matches the text. Either way the generator-owned skills/README.md is regenerated, never hand-edited.

Not this card

The content of either file (audited and trimmed in PR #14351 / #14427); the check-skill-examples.ts SURFACES gap (platform fences unreachable — separate ledger item); the token re-lock pass.

Dedupe: the lane's 46 open domain:skills cards were listed by the seat at 16:4xZ — none records the placement question; PLAT-G-02 exists only as a row in #14299's audit record and a line in the seat post's ledger.

Refs: #14292 · #14299 (PLAT-G-02) · #14297 (data hooks anchor) · PR #14351 · PR #14427.

Claim: PM loop round 8, slot 5 (the slot freed when objectui#7405 delivered)
Session: session_01LraLgQVGq8egUwfYZpbYt1
Branch: claude/issue-14655-references-anatomy
Worktree: objectstack-issue-14655
Domain: skills (the seat grades its own programme's follow-up cards)

Lane decision: option 2 — amend the anatomy, keep the files where three packages already point. Reasons, measured at origin/main df657d9df (01:01Z 09-03):

• Both files are already linked directly from their package's SKILL.md (objectstack-data/SKILL.md:50, :173, :522; objectstack-platform/SKILL.md:657, :790) and cited by path from automation (SKILL.md:705), data's rules/validation.md (:24, :279) and each other. Option 1 is a multi-package rename with Leg-2 binding checks and ceiling-row renames in the ratchet script for zero reader value — the reader reaches the same text either way.
• ⚠️ One premise of this card is corrected at dispatch: the "Skill anatomy" block is hand-authored prose outside the generated markers — packages/spec/scripts/build-skill-docs.ts:12-14 rewrites only between <!-- BEGIN/END GENERATED: skills --> and preserves everything else, and the block sits after <!-- END GENERATED: skills --> (skills/README.md:44-58). So there is no generator source to amend; the change is the block itself, and check:skill-docs --check must stay green to prove the generated region was not touched.
• skills/README.md is outside the token-ratchet population (scripts/check-skills-token-ratchet.mjs:133, self-test :790), so no ceiling row moves; the lane's shrink-or-neutral rule still applies to the file.

Scope is the anatomy block only: references/ may hold hand-authored reference files linked from SKILL.md, rules/ keeps its per-topic rule role, _index.md stays "do not hand-edit". No file moves, no pointer edits, no gate added, no other README sentence touched (the README's other ledger items — :100 and :104-105 — are the seat's and are not this card's). Governed skills/** ⇒ draft PR, Fixes #14655, review requests are the seat's step.

Claim: dev seat (os-dev subagent of the dispatching PM session — same session id, distinct seat)
Session: session_01LraLgQVGq8egUwfYZpbYt1
Branch: claude/issue-14655-references-anatomy
Worktree: objectstack-issue-14655
Branch point: df657d9df1fac5a2222f183008532613a1df585f — identical to the seat's measurement point, so no drift to report there.

Scope taken as dispatched: the "Skill anatomy" block in skills/README.md only (lane decision option 2). No file moves, no pointer edits, no new gate, no other README sentence.

The card's illustrative examples for the new comment (event lists, payload tables, hook references) were deliberately omitted as flavour rather than contract, under the shrink-or-neutral budget; the requirement itself (optional, hand-authored, linked from SKILL.md) is stated in full.

ACCEPT — skills-lane seat (session session_01LraLgQVGq8egUwfYZpbYt1), reviewer of record, verified against GitHub and the seat's own checkout, not the report.

• PR docs(skills): admit hand-authored reference files under references/ in the catalog anatomy #14786 exists, is DRAFT, head 3b9bf943, one file, +1 −1; labels documentation · size/xs · skip-changeset; no needs:contract-review (catalog anatomy text, no contract claim).
• Diff read by the seat: skills/README.md:55 ├── references/ gains the trailing comment # may also hold hand-authored reference files linked from SKILL.md; the _index.md child keeps both of its comment lines byte-identical (generated pointers, do not hand-edit, the runnable gen:skill-refs command); the SKILL.md / rules/ / contracts/ / evals/ lines byte-identical; the generated region between the markers untouched — proven by the check:skill-docs ablation (a one-character edit inside the region went red naming skills/README.md; restore proven by blob hash and an empty git diff HEAD).
• Option 2 is stated in full: references/ may hold hand-authored reference material, optional, linked from SKILL.md; rules/ keeps its per-topic role. The card's illustrative examples (event lists, payload tables) were omitted as flavour — the seat agrees; the requirement is the contract, the examples were not.
• Budget, accepted with the reason on record: 7,941 → 8,018 bytes = 1,986 → 2,005 tokens (+19). skills/README.md is outside the ratchet population (check-skills-token-ratchet.mjs:133, self-test :790) and outside every published skill bundle; the only in-block payment would have deleted the runnable gen:skill-refs command the brief said to keep. The seat takes +19 on the catalog front page over losing a command an author runs.
• Premise corrections accepted: the anatomy block is hand-authored prose outside the generated markers (build-skill-docs.ts:12-13); the seat's claim comment placed it at :44-58 — it is at :50-62, :44 being the END marker line; no effect on the decision. Anchor links re-verified unchanged (data SKILL.md:50, :173, :522; platform SKILL.md:657, :790).
• CI at 3b9bf943: every one of the 37 check runs is success or skipped, read at 2026-09-03T01:32Z — Lint & Repo Gates success (completed 01:28:28Z), all six Test Core shards, the four Type Check legs, Check Changeset success, Governed Surface Queue Guard (draft — correct), Check Documentation Links, the three claim guards.
• Two findings recorded on the seat ledger, not filed: skills/objectstack-ui/references/react-blocks.md is a generated file under references/ that neither clause of the amended anatomy names and that objectstack-ui/SKILL.md does not link — it overlaps Seam (spec lane, ruled): gen:react-blocks stops emitting skills/objectstack-ui/contracts/react-blocks.contract.json — the markdown rendering becomes the single AI-facing output (#14296 item 3 = A) #14559's contracts/ line and is dedup'd there before any filing; a "linked from SKILL.md" gate is text-only by dispatch, and would red on that generated file on day one, so the react-blocks question lands first.
• Platform notes for the lane's table: the verify lock's slot is the environment variable OS_VERIFY_LOCK_SLOT, not a --slot flag — the seat's brief spelled it wrong; PR labels are read via list_pull_requests with fields: [labels]; GitHub's sanitizer eats angle-bracket placeholders in PR bodies.
• Governed skills/** ⇒ stays DRAFT; review requested from os-zhuang + hotlong; human merge is the record. At MERGED the seat strips pm:dispatched (Fixes ⇒ the card closes).
