No gate requires a breaking-behavior changeset to carry the breaking annotation at all — the ADR-0087 disposition gate only fires once one already does #8607

Description

@os-zhuang

Restart-when: the ADR-0087 changeset-gate family is reworked (scripts/check-adr-0087-registration.mjs and siblings, e.g. out of #8299), or a second breaking-behavior changeset lands unmarked

Filed unassigned, surfaced while implementing #8411 (docs-only: annotating .changeset/filter-formula-field-refusal.md as breaking). Cross-references #8410 and #8411, which this card is deliberately kept distinct from — see "Not a duplicate" below.

The gap

scripts/check-adr-0087-registration.mjs's breakingDeclaration() requires an adr-0087: disposition marker only for a changeset that already self-declares breaking, via one of three signals: a major bump, a **BREAKING marker in the body, or a conventional-commit ! on the summary line. scripts/check-changeset-no-major.mjs and scripts/check-empty-changeset.mjs (the other two gates in the same family) don't reason about breakingness at all — one blocks major, the other blocks empty frontmatter.

Nothing in the gate family asks "should this changeset have declared itself breaking, but didn't." An author who writes a changeset for a genuinely breaking behavior change and simply omits the **BREAKING** annotation (or the !, or a major bump) sails through every one of these gates with zero objection, because every one of them only judges changesets that already self-declare — never the prose describing the actual behavior change.

Measured

This is exactly what happened. .changeset/filter-formula-field-refusal.md (landed edff010c, PR #8369) describes a where on a virtual formula field going from 200/zero-rows to 400 INVALID_FIELD at the engine seam — a previously-succeeding call to engine.find / findOne / count / aggregate / update / delete now throws. #8411's own analysis found this the same shape as #7095, which shipped major. Before #8411's fix, running node scripts/check-adr-0087-registration.mjs against that changeset reported:

✓ check-adr-0087-registration: this PR adds no declared-breaking changeset (0 non-breaking changeset(s) seen).

No gate anywhere flagged it. It merged, unmarked, and stayed that way until a human (the PM seat, from #8296's dev's closing report) noticed and filed #8411 by hand.

Not a duplicate of #8410

#8410 (closed, fixed by PR #8465) was about derivation — which gates scripts/pm/dispatch-gates.mjs surfaces for a .changeset/ path, so a dev's local loop matches what CI actually runs. This card is about enforcement — whether any gate, run by anyone, ever asks the question at all. They compound (a derivation gap hides a gate that does exist; this gap means there is no gate to hide), but fixing #8410 does nothing for this: dispatch-gates.mjs now correctly surfaces check:adr-0087-registration for a .changeset/ path (verified live on #8411's PR), and that gate still would not have caught the original unmarked changeset, because it never fires on a changeset that doesn't already claim to be breaking.

Why this is likely NOT a small mechanical fix

Detecting "is this changeset breaking" from prose alone is a semantic judgment call, not a pattern match — the same reason #6148's ADR-0087 gate deliberately asks the author in writing rather than inferring. A mechanical detector here would need to read the code diff (not just the changeset body) and decide whether a described behavior change is actually contract-breaking, which is a different and much harder problem than anything the current gate family attempts. Leaving this open rather than prescribing a fix:

  • Option A — accept no mechanical gate is feasible; rely on PR review / domain-owner sign-off for changes touching known engine/ingress seams.
  • Option B — a narrower lint that flags changesets whose diff touches specific known-sensitive call sites (validation seams, engine filter/sort/search lowering, etc.) for mandatory human confirmation, without claiming general breaking-change detection.
  • Option C — do nothing mechanical; treat this as inherent to the "declare it yourself" convention and rely on the same kind of after-the-fact catch #8296's changeset ships a breaking engine-API change as minor with no breaking annotation — the release digest cannot classify it #8411 exercised.

Whoever picks this up should weigh these on the three axes (real business need / long-term soundness / hard-to-get-wrong for AI-authored changesets) rather than default to building a detector — a false-negative-prone semantic gate that gives false confidence may be worse than the current honestly-absent one.

Refs: #8410 (derivation, fixed), #8411 (the specific unmarked changeset this card generalizes from), #6148 (the ADR-0087 disposition gate's origin and "ask, don't infer" design), #7095 (the sibling engine-seam precedent that shipped major).

    Triage: finding + domain:spec-tooling (held); native type Task. Triage seat Routine, 2026-08-14 ~02:15Z.

    Rationale: the gap is real and measured once (the #8411 changeset), but the one known hit was caught and repaired by the existing human loop, and the card itself argues the strongest point against acting now — a false-negative-prone semantic detector would give false confidence, which is worse than the honestly-absent gate. Putting an appetite question in the decision box with no forcing event would be inbox noise; held as a finding instead.

    Routing: the gate family is scripts/check-adr-0087-registration.mjs and siblings — the ADR-0087 changeset-discipline toolchain, same lane as in-flight #8299. If #8299's PR restructures the disposition categories, fold this question into that review rather than racing it.

    Re-grade triggers (any one fires ⇒ back to triage for promotion or the decision box):

    1. A second breaking-behavior changeset lands unmarked — a repeat of the #8296's changeset ships a breaking engine-API change as minor with no breaking annotation — the release digest cannot classify it #8411 incident. Promotes to needs-user-decision with option B (narrow known-seam lint + mandatory human confirmation) as the concrete proposal.
    2. The ADR-0087 gate family is reworked for any other reason (e.g. out of ADR-0087's changeset disposition has no category for published runtime TS interfaces with no metadata surface — the #8277 exemption argument is correct, unverifiable, and will be re-litigated #8299) — the "should this have declared itself breaking" question rides that redesign.
    3. A cheap high-precision "diff touches a known engine/ingress seam" signal materializes (e.g. from dispatch-gates' path→gate map) — option B stops being speculative.

    State-hygiene completion: swapped finding → pm:on-hold so the label matches the grade already recorded in the 2026-08-14 02:18Z triage comment above (held, with three named re-grade triggers). No new decision here — this is the label half of that same grading action, completed per the grade-means-leaving-the-label discipline (2026-08-13 ruling). Hold provenance: seat grading 2026-08-14; reason and the three restart conditions live in the 02:18Z comment.

    Hold-condition rewrite (triage seat, session session_014qTKTqjme5Fp5BH9iRmy6t, on-hold weak-hit audit): the written rework trigger has fired THREE times without waking this card — scripts/check-adr-0087-registration.mjs was touched by PR #8456 (which closed #8299, the exact example event, two hours after the hold was written), PR #8670, and PR #9560 — all unrelated maintenance that did not revisit this card's question. Verified on origin/main: breakingDeclaration() still reads only self-declared signals (major bump, BREAKING marker, !), so the gap is real and unchanged, and the "ride #8299's redesign" premise is spent (merged and closed).

    Letter fired, intent never did — same treatment as #8360's void leg: the over-broad "family is reworked" trigger is retired and replaced with the condition keyed to what this card is actually about. The hold itself stands (there is still no independent breaking-signal to enforce with).

    Restart-when: a second breaking-behavior changeset lands unmarked (a repeat of #8411), or a PR changes the signal set inside breakingDeclaration() in scripts/check-adr-0087-registration.mjs, or dispatch-gates.mjs gains a path→seam classification usable as option B's known-seam signal

    Measurement input from the triage seat's contract-review round of 2026-08-31. ⛔ The hold stands; nothing is unparked here. Recording live evidence this card has been waiting for, plus one reading that bears directly on which of its three options is right.

    First, the trigger question — answered on the literal, which is NO

    This card's current condition reads:

    Restart-when: a second breaking-behavior changeset lands unmarked (a repeat of #8411), or a PR changes the signal set inside breakingDeclaration()…, or dispatch-gates.mjs gains a path→seam classification…

    Two changesets this round misgraded a breaking behaviour change — but neither landed. Both were caught in draft, before merge, by contract review. ⇒ The first leg has not fired, and the other two have not either. The card stays parked.

    ⚠️ Recording that distinction explicitly because this thread has the mirror precedent: the 2026-08-19 rewrite retired a trigger whose letter fired three times while its intent never did. This is the opposite — intent firing, letter silent — and it would be just as wrong to act on the letter here as it was to keep waiting on it there.

    The measurement — 4 of 5 changesets misstated their own diff, and every gate was green

    Six PRs carried needs:contract-review today; five have verdicts. Their changesets:

    PR what the changeset says what the diff says
    #13829 "@objectstack/spec": patch a required member added to the published IObjectQLEngine. The PR body meanwhile states it "ships @objectstack/spec as minor" and argues minor-vs-major at length — describing a file that does not exist as written
    #13864 '@objectstack/objectql': patch an accept-set narrowing its own text calls "a security fix". The same package's own precedent, .changeset/hook-input-symbol-key-refusal.md, argues verbatim: "Bump level, argued: minor, not patch"
    #13834 "new exports (HookBodyExtractionError, HookBodyRefusalKind, BodyExtractionWarning)" all three are module-private; the package exports map exposes only . and ./console, and src/index.ts re-exports none of them
    #13910 "the last surviving GRANTS-LOST disguise at the package door" ended the shipped single-kernel wiring still answers 403 — its provider absorbs one layer earlier (#13904), verified at head
    #13857 minor + BREAKING banner ✅ matches

    Check Changeset was green on all five. So were check-empty-changeset, check-changeset-no-major and check-adr-0087-registration — exactly as this card predicts, because each judges only a changeset that already self-declares.

    ⭐ The reading that bears on the option choice

    This card's three options end with a warning against defaulting to a detector. That warning is now stronger, and one option has evidence it did not have in August:

    ⇒ The sharper question this round suggests, offered as input rather than as a proposal: is the gap "no gate asks", or "the gate that does ask is reachable only through a route with its own coverage holes"? Option B's known-seam signal and the clause-② path limb are the same kind of object — a path→consequence map — and #13922 has just measured that the clause-② gate's own carriers are out of sync 4 times in 6.

    Refs

    ⛔ No labels touched, no state changed, no option chosen — this is patrol input for whoever prices this card.
