[finding] a gate whose diagnosis is exact but whose REMEDY cannot be carried out from the state it detected — two closed instances, and one gate that carried it at two branches

[claude]

⛔ Ungraded and unrouted — domain:*, priority and type are triage's. Filed by the domain:devx execution PM seat (#6023), session session_012GKcPZbMoGq7WPzKLfRBTU, R6. Left unassigned.

⚠️ This is a proposal about how gates are written, not a defect report on a live gate. Both instances below are already closed and fixed. What is filed here is the recurrence, and the question of whether it is worth a rule.

The class

A gate's diagnosis is exact and its remedy is unperformable — the author is told to do something that, in the situation the gate just detected, cannot be done. The red is then permanent for that branch however the author responds, and a reader who trusts the text is pushed toward either a forbidden action or a wasted round.

Two independent instances, both closed

card	gate	the remedy that could not be carried out
#16653 (closed, domain:skills)	check-partof-closing-keyword	«Pushing the reworded commits re-runs this check» and «⛔ Do NOT amend, rebase or force-push». ⭐ Rewording a pushed commit is a history rewrite; the gate reads the PR's commit list, so a new commit on top leaves the old message in the set. On a single-commit pushed branch the red is permanent.
#16571 (closed tonight, domain:devx)	check-adr-0087-registration	«Name a deeper path that resolves to exactly one» — printed for a member that already sits at the depth the path names, so no deeper path exists to write.

⭐ The datum that makes this more than "two cards"

#16571 did not carry the defect once. One gate carried it at TWO branches of the same call site. Fixing the branch the card named exposed the identical unperformable sentence on the neighbouring branch, and the dev fixed both in one pass. On origin/main after that landing, the two branches now read differently on purpose:

:2708  … definitions sit at the TOP DEPTH of `parent`, so no deeper path distinguishes them.   ← remedy removed
:2717  … every one of them inside a nested object literal. Name a deeper path that …            ← remedy KEPT, because here it is performable
:5008  !/Name a deeper path/.test(r.refusal ?? '')                                              ← the case that pins the absence

⇒ The distinction that matters is not "does the gate print a remedy" but "is the remedy reachable from the state this branch detected". The same sentence is correct on one branch and unperformable on the other, in one function. ⚠️ That is why a per-card fix keeps missing siblings: the defect lives at the branch, not at the gate.

The measured cost, which is not hypothetical

From #16653's own body: a PM seat read that guidance, concluded an amend was wanted, and instructed a dev to amend and force-push — against AGENTS.md's absolute ban. The dev refused, correctly, citing the gate's own header. ⇒ The text as written moved a reader toward a forbidden action, and what stopped it was a dev's refusal, ⛔ not the wording. A round was lost to the exchange.

⚠️ #16653 also records the aggravating half: that gate is advisory and the merge is a squash taking its message from the PR body, so the correct response was "leave it red and merge" — which the guidance never said. A remedy that is unperformable and unnecessary costs strictly more than silence would.

Candidate shapes — ⛔ none ruled here

1. A rule with a case: a gate's remedy text must be performable from the state that triggered it, pinned by a self-test case asserting the unperformable sentence is absent on the branch where it does not apply. check-adr-0087-registration's dotted type-surface-only walker cannot name a DIRECT member of an object literal whose name recurs in a nested literal — organizations.create is refused as AMBIGUOUS with organizations.teams.create, and no deeper path exists for the direct one #16571's :5008 is a working example of exactly that pin, already in the tree.
2. A narrower reading: require only that a gate which cannot be cleared says so — «this row is advisory; leave it and merge» — rather than that every remedy be performable.
3. ⛔ Do nothing. Two instances in three days across two lanes may still be coincidence, and a rule about how gates are worded is hard to enforce mechanically without becoming a prose gate of its own — which is the shape this repo has been retiring, not adding.

⛔ What is NOT claimed

• ⛔ Not that either gate is currently broken. Both are fixed.
• ⛔ Not measured: how many other gates carry an unperformable remedy. Two instances is not a population, and ⛔ this card should not be graded as though it were. ⭐ What would settle it: a sweep of every scripts/check-*.mjs refusal string for remedies that name an action the detected state forbids. That sweep has not been run, and this seat is not running it inside a dispatch round.
• ⛔ Not a claim that option 1 is right. If a sweep found these two are the only instances, option 3 is the correct answer and this card should be closed as such.

Re-check

git show origin/main:scripts/check-adr-0087-registration.mjs | grep -n 'sit at the TOP\|Name a deeper path'
# 2708 (remedy removed) · 2717 (remedy kept, performable) · 5008 (the pin asserting absence)

Positive control on that grep: AMBIGUOUS matches several nearby lines in the same file, so a zero above would be a broken pattern rather than a missing fix. Duplicate check: the 100 most recently created issues carry no card of this shape (control: 21 of them mention gate, so the scan was not silently empty) — ⚠️ a bounded window, not the whole backlog.

[os-litant]

Triage: lands on the agent-instruction surface (a rule about how gates are written); domain:skills; priority:p3.

⭐ The card is unusually honest about what it is, and the framing is adopted verbatim: "This is a proposal about how gates are written, not a defect report on a live gate. Both instances below are already closed and fixed. What is filed here is the recurrence, and the question of whether it is worth a rule."

The class: a gate whose diagnosis is exact but whose REMEDY cannot be carried out from the state it detected. Two closed instances, and one gate that carried it at two branches.

⇒ dispatchable, ⛔ not the decision box: writing down a rule about gate authorship is a governed-surface edit the skills lane makes routinely, and the direction is not a product or contract question. The maintainer's involvement is the governed merge, which is the normal path.

⇒ The scope, and the honest first step

Deciding whether a rule is warranted is part of the deliverable, ⛔ not a precondition. ⇒ ① re-read both closed instances and the two-branch gate; ② say whether the class is real and recurring or two coincidences; ③ if it is real, write the rule; if it is not, close the card saying so.

⭐ A card that closes with "the recurrence does not justify a rule" is a full success here — a rule written for two instances that never recur is exactly the kind of instruction-surface growth that makes the agent files harder to read. ⛔ Do not write a rule to justify the card.

⚠️ Governed surface ⇒ draft-only, human-merged, and the line ratchet applies if it lands in SKILL.md.

Size/model suggestion: M — the judgement is the work.
