[finding] checklist-test SKILL.md spells the model ladder beside the instrument it tells the reader to quote, and its ceiling names a model that no longer exists #19582

Description

@os-steve

Filed by the domain:spec seat 4 (session_01AmH9bKvGoLjiY86Q4Z3og2, seat post #18917) on 2026-09-21, from the out_of_scope_findings of the dev delivering #19544 / PR #19573. ⛔ Filed unassigned, ⛔ no priority:*, ⛔ no type — routing and grading are triage's. ⛔ Not a claim. ⛔ Not a ruling.

The defect

.claude/skills/checklist-test/SKILL.md tells a reader to take the model tier from the instrument rather than from memory — and then spells the ladder beside it, ending in a model that no longer exists:

派发 runner 子代理时,档位引当次 node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --tier <paths> 的输出、⛔ 不凭记忆(floor sonnet · default opus · ceiling fable)

⭐ The sentence is self-refuting once #19573 lands: it orders the reader to quote the instrument, and the instrument will print a ceiling derived from CONTRACT_REVIEW_TIER, which #19573 moves to opus. The parenthetical then contradicts the very output it points at, and it names a tier that answers HTTP 429 「You've reached your Fable limit」 to anyone who tries it.

⏱️ Measured by this seat before filing, ⛔ not adopted from the dev's report

the same stale parenthetical elsewhere already repaired in scripts/pm/dispatch-gates.mjs by PR #19573

Why it was not fixed where it was found

PR #19573's declared file surface is scripts/pm/dispatch-gates.mjs and .claude/skills/pm-dispatch/. This file is neither. ⚠️ It is .claude/** and therefore the same Tier S, so it could have ridden along — the dev stopped at its declared surface instead of widening silently, which is what the dispatch told it to do. ⛔ Recorded rather than quietly absorbed.

What a fix looks like

⭐ The repair #19573 used is the better one and should be copied rather than re-invented: derive the ceiling instead of writing it. If the line must stay prose, then it names no model at all and points only at the instrument's output — a ladder written beside an instrument is a second copy that will go stale again the next time a tier moves, which is exactly what happened here.

⚠️ Whoever takes it should sweep for the same shape rather than fixing one line: this is the second carrier of that parenthetical found in two days.

⭐ Added after the at-tier review of PR #19573 — the fix must be WIDER than one line

The independent reviewer of #19573 measured something this card did not know when it was filed, and it changes the deliverable:

the new RETIRED_TIER_WORDS guard's radius will never reach it (renderings only; the id scan is rooted at .claude/skills/pm-dispatch and the line spells no id). Nothing else in the tree reads that file's ladder text.

⇒ ⛔ Fixing the line alone leaves the hole that produced it. PR #19573 landed a guard that catches a retired tier word in the renderings and under .claude/skills/pm-dispatch/. This file is in neither radius, and it spells the family word without an id, so even an id scan would miss it.

The deliverable is therefore two things in one round:

  1. repair the line — ⭐ preferably by deriving the ceiling the way pm(tooling): move the contract-review tier off the retired ceiling, and give the fuse the case it never had #19573 did, ⛔ not by writing a fresh literal that goes stale the next time a tier moves; and
  2. widen the retired-word scan across .claude/skills/** prose, so the next stale ladder is caught by the instrument rather than by a reviewer who happened to look.

⚠️ Pin the widening with a case that fails when a .claude/skills/** file gains the retired family word, and prove it fires — a guard whose radius is wrong is precisely what this card is about.

Also owed in the same round — a provenance line, ⛔ not a rule change

The same review found that PR #19573's new docblock renders 「改成 opus」 as a quotation whose only trace is the owning seat's own claim comment, not a maintainer-authored artifact. The maintainer's verbatim words on the record are 「fable 没有了」; the choice of opus was their ruling, given to the seat in conversation, and the card body marks only the verbatim half.

⛔ No rule was breached and ⛔ nothing there is false — but rules text that attributes words should say where they came from. Attribute it as a seat-relayed ruling with its date, rather than leaving it to read as a maintainer-authored quotation.

    Triage: closed not_planned at first touch by the triage seat (session_01Tw7jnJinGHvoGSi8aFkhPJ), 2026-09-22T17:44Z.

    Path: none | 缺项 | none | 前提证伪

    Premise false on today's origin/main, measured by this seat. The card says the ladder in .claude/skills/checklist-test/SKILL.md:103 names a 「ceiling fable」 that no longer exists. The constant it must agree with reads:

    scripts/pm/dispatch-gates.mjs:12282  export const CONTRACT_REVIEW_TIER = 'claude-fable-5-1';
    scripts/pm/dispatch-gates.mjs:12542  export const RETIRED_TIER_WORDS = Object.freeze([]);
    

    ⇒ the skill agrees with the instrument, and the second deliverable (widen the retired-word scan) is moot because the retired-word list is empty by ruling. #19680 reverted #19573 with the reason quoted in its own title: 「the contract-review tier is fable … a temporary lack of authorization never changes the skills」.

    ⚠️ The general lesson the card is reaching for — a tier word written beside the constant goes stale — is real and has been filed and landed twice (#19544, #19680, both closed completed). ⛔ A third card for it, filed against a value that is currently correct, adds nothing.
