skills/objectstack-automation still calls the api flow secret optional and says type: 'api' can be invoked explicitly only — both false since PR #20551 (split from #20553)

Filing gate: ① a product defect with a named landing site. Class (b): a published skill contradicts the runtime and the Accepted ADR. reach: is a named real producer: skills/objectstack-automation/SKILL.md, which an authoring agent loads. It also ships to generated projects through create-objectstack.

Split by the triage seat (objectstack-wide, seat post #6015, session_01AavokzJ5DndAwitDXvKy4U) from #20553, items 1 and 2, when it graded that card. #20553 keeps the os validate half (domain:spec). This card is the skills-lane half, because skills/** is a Tier H governed surface. The evidence below is #20553's, filed by the domain:services seat (#6021) from the #20529 dev report 5882379577.

What is false (read at `origin/main` `03b19d9c`, per #20553)

skills/objectstack-automation/SKILL.md:356, the secret row: "HMAC-SHA256 shared secret. Strongly recommended — without it unsigned posts are accepted and a warning is logged".
- ADR-0041 (Accepted) requires a per-flow secret.
- Since PR fix(trigger-api,service-automation): refuse an api flow with no per-flow secret, at arm time and at registration (#20529) #20551 (trigger-api arms a flow's inbound hook without a secret and accepts unsigned posts; ADR-0041's trigger-api acceptance criteria name a per-flow secret and HMAC verification #20529, merged 2026-09-29), the runtime refuses an api flow with no non-blank config.secret: 400 VALIDATION_FAILED on the /automation write doors, and a skip with a warning at boot.
skills/objectstack-automation/SKILL.md:52, the api row: "Invoked explicitly via the API / engine.execute(), or bound as an inbound webhook".
- The engine binds every api-kind flow to the inbound trigger, so no "invoked explicitly only" form of type: 'api' exists.
- The explicit-only form is type: 'autolaunched', as PR fix(trigger-api,service-automation): refuse an api flow with no per-flow secret, at arm time and at registration (#20529) #20551's changeset says.

Re-check (from #20553): git grep -n "Strongly recommended — without it unsigned posts are accepted" origin/main -- skills/objectstack-automation/SKILL.md and git grep -n "Invoked explicitly via the API" origin/main -- skills/objectstack-automation/SKILL.md each expect 1 hit.

Direction (triage's grade, on the first comment)

:356: the secret is required. The row says what happens without one, which is refused at registration and not armed at boot, and names the header the signature goes in.
:52: api is the inbound-webhook kind and always needs a secret. The explicit-only form is autolaunched.
Before editing, census the other skills/** and content/docs/** lines that describe the api trigger or its secret.
⛔ Keep it abstract under the security disclosure rule: no request recipe ([security] a flow's inbound-hook secret (config.secret on the start node) is served in cleartext by the flow-definition read; after #20529 every armed hook carries one #20552 is the open security card on the same secret).
Tier H: a draft PR that the maintainer merges.

Dedupe: the family search in #20553 (「api trigger secret os validate skill objectstack-automation inbound webhook secret optional」: #20529, #8025 and #7722) found no card for these lines.

Dedupe words: objectstack-automation skill api secret optional · type api invoked explicitly autolaunched · skill trigger-api secret required

Reading for this card, from the domain:engine seat (session_01DEvba2nBuD4tWzfq8r8NFY) · 2026-09-29T18:41Z. ⛔ Not a claim.

PR #20692 (#20611) landed as 31ed06763: /meta now also refuses a secretless api flow, answering 422 INVALID_METADATA with flow-api-trigger-secret-missing, and nothing is stored (pinned in protocol.metadata-redaction.test.ts). With the engine's registration refusal (17.5.0) and os validate (#20553), every door now refuses the flow that skills/objectstack-automation/SKILL.md still describes.

Line 356 says secret is "Strongly recommended — without it unsigned posts are accepted and a warning is logged".
Line 52 says a type: 'api' flow can be "Invoked explicitly via the API / engine.execute()" (an explicit-only flow is autolaunched).

The at-tier record 5895956737 on PR #20692 judged both lines false on main. This card's reach is now every authoring door. skills/** is Tier H.

Readings at 2026-09-30T06:34Z on origin/main 7a09eee1: :51 still reads "Invoked explicitly via the API / engine.execute(), or bound as an inbound webhook"; :350 still reads "Strongly recommended — without it unsigned posts are accepted and a warning is logged".

Three in-file payments for the token ceiling: the hook route is stated once (:343, the section the row points to), the Signature bullet keeps only the value shape (`sha256=` plus hex), and the :344-345 clause 'so these keys are read at runtime, not Zod-validated' (now false for `secret`) is cut to 'with no Zod shape'; :342 'can be bound' became 'is bound'.

Implemented-by: claude/issue-20569-automation-skill-api-secret (dev report 5905964684). Reviewed-by: session_01KTZmMfzVzjNvyaLyQ8mHvg.

Review checklist, read on GitHub (not the report):

Shape: draft, base main, first body line Fixes #20569, Clause-②: no at a line start. One file, skills/objectstack-automation/SKILL.md, +5 / −6 — inside the claim surface; Tier H (skills/**). The http row and the examples-flows Slack node (PR docs(skills): objectstack-automation routes an outbound credential to a connector credentialRef and drops the Slack webhook-url example #20778's) are untouched.
Diff read by the seat against the card's direction: the api row names the inbound hook, the required start-node secret and autolaunched as the explicit-only form; the secret row says Required, refused at registration (os validate too) and never armed at boot, and names x-objectstack-signature (packages/triggers/trigger-api/src/plugin.ts:89 on main); three in-file token payments, each with a home in the same file. No request recipe beyond what main already stated.
Budgets: net −1 line (budget +2); SKILL.md 5782 / 5785 tokens, no ceiling moved.
Changeset: skip-changeset on the PR (the dev's label write succeeded this round), assignee os-warren. The one Check Changeset red is the opened-event run that predates the label; the labeled run is skipped.
CI on 32847a29 at this ACCEPT: 22 success, 11 path-filtered skipped, Lint & Repo Gates still in_progress (a required context — not a pass; it must conclude success before landing), 1 stale Check Changeset red as above.
## Contract review PASS on this head: 5906148151 (rendered at CONTRACT_REVIEW_TIER by an isolated subagent — this seat is below tier — and adopted by the seat; its transcript served claude-fable-5-1). It judged every changed statement at the code on every door (engine registration, boot, trigger-api, the /automation write door, os validate, /meta) and found every deletion homed and no contradiction in the skill or content/docs/automation/**.
Report: mcp_calls 0; api_writes three relay writes (pr_create, label-write, the report) plus two pushes.

Out-of-scope findings: content/docs/automation/flows.mdx:92 (the api row names neither the hook nor the required secret — true but incomplete) and webhooks.mdx:733–:736 (a stale non-goals note, not false) → dropped: neither is a false statement, and an incomplete sentence is a coverage gap, not a defect card; noted in this ACCEPT for the docs lane's next edit of those pages.

Landing: Tier H — the PR stays draft and awaits an authorized APPROVED review; needs-user-decision goes on the PR and review is requested from os-zhuang and hotlong in this same act; the final 维护者速读 is posted on the PR.

Delivered by PR #20796, MERGED 2026-09-30T08:52Z through the merge queue as eac538c9.

Content confirmed on origin/main:
- skills/objectstack-automation/SKILL.md:51 calls api the inbound-webhook kind that needs a start-node secret, and names autolaunched as the explicit-only form;
- :349 says the secret is Required: refused at registration (os validate too), never armed at boot, signature in x-objectstack-signature.
Landing record: ## Contract review PASS 5906148151 on 32847a29 (the landing head), ACCEPT 5906165199, and authorized approval by os-zhuang (5363562821, a GOVERNED_APPROVERS account). The approver readied it, armed auto-merge and queued it.
Fixes #20569 did not close this card at merge (the fifth queue merge in a row this shift), so the seat closes it here; pm:dispatched comes off and the assignee is cleared.
