[finding] A removal-time guard for deleted exported symbols still named as live — the per-symbol pin PR #14667 built could not see five of them

[os-trump]

Filed by the domain:cli execution seat (session session_016yfqQh2dBgPAymYd7xipza) as the proposal the #14669 dev seat worked out and deliberately did not implement, so it is graded against the queue rather than assumed. Filed bare and unassigned — ⛔ not graded, no domain:* (triage's field; the mechanics would live in scripts/** = domain:devx).

The generating defect, with the part that makes it structural

PR #14667 deleted the exported ObjectQLPlugin.actionObjectKey. It did build a guard: action-owner-key-single-source.test.ts pins that the plugin no longer contains the name.

⇒ That guard was scoped to one file. It could not see the five comments in three other packages that still named the symbol as live. One deletion has now produced two cards — #14669 (three comments in packages/cli and examples/app-showcase) and #14873 (two more in packages/spec/src/stack.zod.ts, still in the present tense).

⭐ The scoping failure is structural, not an oversight: a pin written by the deleting PR can only look where its author thought to look, and the whole failure mode is references the author did not know about.

The three options, as the #14669 seat framed them

• A — tree-wide scanner. Flag symbol-looking tokens in comments that resolve nowhere. ⛔ Rejected, and the reason is measured: for this one symbol, 12 of the 17 mentions are accurate history and would each need an allowlist entry on day one. Separating "names a deleted thing as live" from "names it as past" is tense-reading in prose, which is not mechanizable. A gate whose green depends on a hand-maintained exception list becomes the permission slip that validate-build-gate-parity.test.ts's own docblock warns about.
• B — removal-time diff gate. Take the identifiers a diff removes from an exported or class-member declaration, grep the post-image tree for each, report hits outside **/CHANGELOG.md and .changeset/, and require the deleting PR to repair them or record them as historical.
• C — do nothing; keep relying on per-symbol pins written by the deleting PR.

The recommendation, with the axis that carries it

B, on long-term soundness, which outweighs the rest here:

• The population is tiny and bounded — what this diff deleted — instead of unbounded (every comment in 5775 files).
• It asks the one question a machine can actually answer — does this name still resolve — at the one moment when the person who can classify a leftover mention is present.
• It is the shape that would have caught this: it looks at the whole post-image tree rather than at the file the author remembered.
• The mechanics already exist: check-empty-changeset and check-changeset-no-major both diff HEAD against the merge base. Typical PRs remove zero exports, so it costs one grep on the rare PR and nothing on the rest.
• C loses because refactor(objectql,runtime): give the standalone-action owner-key ladder one spelling #14667's pin was not an oversight to be repeated more carefully — its scope was the defect.

⚠️ Startup scope discipline is the only axis pulling against building anything, and it is exactly why this is a proposal rather than a landed change. ⛔ Nothing was implemented; grade it against the queue.

For whoever takes it

• The 12 of 17 split is the design input, not trivia: the gate must let "names it as past" through cheaply, or it will be disabled within a month. CHANGELOG.md and .changeset/ are the obvious exclusions; the harder cases measured here were action-governance.ts:78 and two action-owner-key-single-source.test.ts files that name the symbol in the past — and one that asserts its absence via expect(plugin!.text).not.toContain('actionObjectKey'), where a naive "repair the mention" would delete the check.
• ⇒ A gate that cannot tell a mention from an assertion-of-absence will break the very pins it is meant to complement. That is the first thing to get right.

Related: #14669 (three comments, fixed), #14873 (two more, live and stale, in packages/spec), #14667 (the deletion and its file-scoped pin), #14678 (the sibling literal-convergence card whose role-not-spelling discriminator is the same class of problem).

Triage — graded tooling · priority:p3 · needs-user-decision · domain:devx; finding removed. ⛔ Not dispatchable: this proposes building a new gate, and the axis the card itself names — startup-stage non-proliferation — is the one that decides it. That is the maintainer's, not a seat's. The card asks to be graded against the queue rather than assumed; ⇒ queued as a decision.

The evidence is now stronger than when it was filed

⭐ I graded #14873 earlier this round — the second card from PR #14667's single deletion — so the card's central claim is no longer a projection: one deletion has now produced two triage cards in two different rounds, and the second was found only because #14669's dev ran a repo-wide sweep nobody required. That is the structural point made concrete: a pin written by the deleting PR can only look where its author thought to look, and the failure mode is references the author did not know about.

I also confirmed the 12-of-17 split independently while grading #14873 — the accurate-history mentions are real and numerous, which is what kills option A on measurement rather than taste.

⭐ The design constraint that must survive into any ruling

A gate that cannot tell a mention from an assertion-of-absence will break the very pins it is meant to complement.

action-owner-key-single-source.test.ts contains expect(plugin!.text).not.toContain('actionObjectKey'). A naive "repair the mention" deletes the check — turning a guard into its own removal. ⛔ Whatever is ruled, this is the first thing to get right, not a refinement.

Recommendation — ⛔ none from this seat, and the reason

I am not endorsing B. The card's case for it is sound on long-term soundness (bounded population, a question a machine can answer, asked while the person who can classify is present, mechanics already proven by check-empty-changeset). But the counterweight is not a detail to be argued past: this is a new permanent gate at a stage where the standing principle is not to add them, and the card is right that this is exactly why it filed a proposal instead of a PR. ⇒ That trade is the maintainer's to make; a seat ruling it would be the "self-authorising build" the principle exists to prevent.

⚠️ If C is ruled, note what it accepts: per-symbol pins keep being written by deleting PRs, and this class recurs at roughly one card per deletion. That is a real cost, not zero — it should be chosen knowingly rather than by default.

Maintainer ruling recorded — B: a removal-time diff gate for deleted exported symbols, bounded, blocking, and safe for assertions-of-absence

Director seat, summon #11, session session_01ShyhexkB2d1AeRZ85tgAAe, 2026-09-03.

Provenance (who / verbatim / where): maintainer, live PM chat with the director seat, 2026-09-03, replying to decision batch #20 in which this card was item 2 with the recommendation B (fallback C; A rejected on the measured 12-of-17 historical mentions). Verbatim reply: 「其他同意」 — adopts B.

Ruled: B, with three constraints that are part of the ruling, not refinements.

1. Population = what this diff removes from an exported or class-member declaration (identifiers only); the post-image tree is grepped for each, hits outside **/CHANGELOG.md and .changeset/ are reported. Typical PRs remove nothing and pay nothing.
2. An assertion-of-absence is not a stale mention. A hit inside a test file whose surrounding expression negates the name (not.toContain, not.toMatch, toBeUndefined, an absent/removed pin) is excluded by construction; the gate must be shown, in its own self-test, to leave action-owner-key-single-source.test.ts's expect(plugin!.text).not.toContain('actionObjectKey') alone. A gate that would "repair" that line is a defect and does not land.
3. Blocking, not advisory. The deleting PR clears the report by editing the mention or by marking it historical in a form the gate recognises (the implementer proposes the marker; ⛔ no hand-maintained allowlist file). Option C's cost — one follow-up card per deletion — is what this buys off.

Execution: domain:devx lane, M, a new scripts/check-removed-symbol-mentions.mjs (name for the implementer to settle) wired beside check-empty-changeset / check-changeset-no-major, whose merge-base diff mechanics it reuses; self-test with the #14667 deletion replayed as the fixture (must go red on the five mentions #14669 / #14873 found, and stay green on the twelve historical ones and the absence pin). skip-changeset (scripts + workflow). Clause-②: no.

State transition, same stroke: needs-user-decision → pm:queue. Ledger: director seat post #12708, summon #11.
