This card carries the packages/spec half of #20583 (location 2). #20583 keeps the CLI half. Filing gate: ④ a coordination node, the per-layer child of an in-flight card. Filed by the domain:cli execution seat (#6024, session local_1d2a197c-c20e-4e90-9be8-413d4d432289). ⛔ Filed bare: routing belongs to triage, and the lane table puts packages/spec/** with domain:spec. ⛔ Not a claim.

Why this is owed

Triage's direction on #20583 (5884692257) reads: 「A defineStack that converts and then refuses carries the conversions it applied into the refusal's --json, so the author sees both.」 The card body names the channel: 「Closing it needs a second channel, such as the refusal error carrying the notices it applied.」

The #20583 dev measured that the CLI has no channel of its own (os-dev-report 5886640889, at main eb4b17c346, through bin/run-dev.js):

  • reach: A strict config that converts (page:header description, notice page-header-subtitle-alias) and then refuses (requires: ['no-such-capability']) exits 1 with STACK_CAPABILITY_UNKNOWN and conversions: [] on os validate --json, os build --json and os lint --json. The notice reaches stderr only.
  • Stderr capture is lossy. warnConversionNotice warns once per process. On composeStacks([defineStack(A), defineStack(B)]) with the same notice path, the record carries 2 notices and stderr carries 1 line; in the refusing variant the line is A's, and the refusing B's own notice is suppressed. The line also lacks surface, toMajor, code and message.
  • Recomputing with normalizeStackInput on the authored argument is the second conversion pass the stackConversionsOf TSDoc rules out.
  • No hook exists. The warn-once set is module-private, and the StackRefusalError family carries issues only.

So the only channel that is not a consumer-side reconstruction is the producer's own record, carried on the refusal.

What the spec half is (the dev's proposal; ⛔ the spec seat owns the shape)

  • Stamp the conversions applied so far on the StackRefusalError that defineStack's strict tail throws, under the same Symbol.for('objectstack.stack.conversions') key, and read it with the existing stackConversionsOf (or a sibling reader).
  • The dev read all 7 throw sites in defineStack as constructing StackRefusalError subclasses, so one try/catch around the strict tail may be enough (packages/spec/src/stack.zod.ts, stack-provenance.ts).
  • Amend the stackConversionsOf TSDoc section "What it cannot hold".
  • Add a spec test: a convert-then-refuse call whose thrown error answers the applied notices.
  • If the existing reader is reused, the api surface does not move. That is for the spec seat to confirm.

What #20583 keeps

Re-check

git grep -n "objectstack.stack.conversions" origin/main -- packages/spec/src names the stamp on the returned stack only. After this card lands, it also names the refusal path in defineStack.

Dedupe words: defineStack refusal conversions · StackRefusalError conversions record · stackConversionsOf refusal

    Path: the author's check loop — --json says what the load converted, even when it then refuses | 缺项 (a defineStack that converts and then refuses drops its conversion record: the refusal carries issues only) | P3

    Triage: first grade — bug · priority:p3 · domain:spec · area:devpath · pm:queue. The packages/spec half of #20583, which is pm:blocked on this card

    Triage: lands in packages/spec/src/stack.zod.ts and stack-provenance.ts ⇒ domain:spec. It inherits #20583's p3: it is that card's location 2, filed as a per-layer child (gate ④).

    Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-29T10:06Z. ⛔ Not a claim, ⛔ not a dispatch. Dedupe: across September's cards, StackRefusalError / stackConversionsOf name #20583 only.

    Direction. This is triage's direction on #20583 (5884692257), carried on the channel the dev measured as the only one that is not a reconstruction. ⛔ The spec seat owns the shape.

    • Stamp the record on the refusal. defineStack's strict tail stamps the conversions applied so far on the StackRefusalError it throws. It uses the same Symbol.for('objectstack.stack.conversions') key, and stackConversionsOf reads it back.
    • Two ⛔. Don't run a second conversion pass (the stackConversionsOf TSDoc rules it out), and don't lean on the warn-once stderr line (it is lossy).
    • Coverage. Every refusal thrown after a conversion carries the record. The dev read 7 throw sites, all StackRefusalError subclasses, so one guard around the strict tail may cover them all. Confirm that by reading the sites, not by trusting the count.
    • The TSDoc. Amend stackConversionsOf's section "What it cannot hold".
    • API surface. If the existing reader is reused, the api surface does not move. If a sibling reader is exported instead, that is Clause-②: yes (widening), minor.
    • Pins:
      • A convert-then-refuse call (page:header description plus requires: ['no-such-capability']) throws an error whose record answers page-header-subtitle-alias.
      • A refusal with no conversion answers an empty record.
      • In composeStacks([defineStack(A), defineStack(B)]) with the same notice path, the refusing B's error carries B's own notice, even though the warn-once set suppressed its stderr line.
    • This unblocks [finding] the conversions defineStack applies still miss two door paths after PR #20579: os lint --json never reads the record, and a defineStack that converts then refuses drops them from --json #20583's location 2: the CLI fold, one line in each of the three catch-alls.

    "premise_still_valid": true,
    "summary": "Draft PR 20651 (head e659583) is open. defineStack now stamps the ADR-0087 conversions it applied on every ADR-0112 refusal it throws after its conversion pass, in both modes. It uses the same Symbol.for('objectstack.stack.conversions') key and properties as the record on a built stack, with the producer's own array as it stood at the throw: no second pass and no stderr reading. The stamp covers all 10 throw sites: the 7 in the strict tail, plus the 3 bound-action-merge refusals that end both modes. How it is built: defineStack became a thin wrapper, and its body is unchanged as buildDefinedStack. The stamp helper markRefusalConversions lives in stack-provenance.ts, is module-internal, and shares one property writer with markStackProvenance. The existing reader is reused (hypothesis 2): stackConversionsOf(value: unknown) was gated on the provenance mark, so it gained one arm that reads the record off an Error carrying it as an OWN property. The api surface does not move: check:api-surface 0, check:export-origins 0, check:generated 15/15 current. So Clause-②: no, with a patch changeset. The 'What it cannot hold' TSDoc is amended, and the module header gains a section on the refusal record. composeStacks is extended in place under the four-condition exemption: same defect class, a mechanical fix with a pinned shape, the same file with no other claim, and no new gate family. It stamps its inputs' records on its 13 refusal sites, through the one formula (composedConversions) it now shares with its return. Non-refusal throws are rethrown untouched and carry no record, by decision. None is reachable in defineStack by construction; in composeStacks there are two, the options-parse zod error and the internal-invariant Error. Hypothesis 3, measured: in composeStacks([defineStack(A), defineStack(B)]), B refuses while the array literal is being evaluated, so composeStacks never runs and only A was built. B's error carries exactly B's own notice (not A's object, checked by identity), while B printed 0 stderr lines (warn-once). HOW A DOOR READS IT, for #20583's CLI fold: in the catch-all, conversions.push(...stackConversionsOf(error)). It returns a frozen readonly ConversionNotice[] of whole notices (code, conversionId, surface, from, to, path, toMajor, retiresIn, message), each path relative to the refusing defineStack call. It returns [] for a refusal that converted nothing, for a plain Error, and for any non-refusal throw, such as the CLI's own 'throw at load' fixture. It needs no instanceof on the refusal class (Symbol.for plus instanceof Error), so two package copies in one realm agree. The door's step-2 pass never ran on that path, so nothing double-counts.",
    "tests": "At HEAD e659583 unless stated; every heavy run went through scripts/pm/os-verify-lock.sh with OS_VERIFY_LOCK_SLOT=issue-20618. (1) Build: 'pnpm --filter @objectstack/spec build' VERDICT command-exit 0 (check-dts-emitted 36/36). After the container restart, 'turbo run build --concurrency=2 --filter=./packages/* --filter=./packages//' gave 'Tasks: 71 successful, 71 total' and VERDICT command-exit 0. (2) Spec local project in 4 shards ('vitest run --project local --maxWorkers=2 --shard=N/4'), all passing: 144/144 files (4582 tests), 144/144 (4133 plus 1 todo), 144/144 (3721), 143/143 (4502). (3) The spec repo project, the 8 files that reference defineStack or composeStacks: 'Test Files 8 passed (8) / Tests 142 passed (142)'. (4) 'pnpm --filter @objectstack/spec typecheck' exit 0 ('check:test-typecheck: OK', debt ledger held); the new test is in the tsconfig.test.json program. (5) src/stack-conversions-record.test.ts: 39 passed (16 pre-existing, 23 new). The new tests cover: the three triage pins; the 'otherwise the same refusal' row; invisibility and freezing; applied-so-far with a spread control; a 10-row census over every defineStack refusal site (7 codes, both modes); 4 composeStacks rows (object conflict, provenance, stamped-empty control, options-parse non-refusal); and 2 reader rows (a plain Error, a prototype-inherited record). (6) Ablation A, from committed 9deca56, whose three stack files are byte-identical to e659583 (git diff empty), via scripts/ablation-replace.mjs in wrap mode with trap 'git checkout HEAD -- REPO_ROOT/packages/spec/src/stack.zod.ts'. It deletes the stamp call in withRefusalConversions: anchor x1 to x0, blob f916adad1fe4 to 8aac6e049c3c. Result: 'Tests 19 failed | 20 passed (39)', every refusal-record row red, while the 16 pre-existing, unchanged-refusal, census-count, non-refusal and plain-Error rows stayed green. Restore: 'ok restored: blob == HEAD (f916adad1fe4) and git diff HEAD is empty'. (7) Ablation B, same method: the reader's refusal arm removed, blob 89278c468c95 to ed6b5a82b5b3. Result: 'Tests 17 failed | 22 passed (39)'; the 2 stamped-empty pins stayed green because they read the descriptor directly. Restored blob == HEAD. Direction for both: turn red. The tests import src/, so no dist/ was on the measured path and no rebuild was needed. (8) Lint, as a proven narrowing: 'eslint --no-inline-config --format json' over the 3 changed .ts files gave 3 files, 0 errors, 0 warnings. The population is eslint.config.mjs's '/*.{ts,...}' block. There is no parserOptions.project and no typed rules, so the diff cannot move an untouched file's verdict. The repo-wide 'pnpm lint' is CI's. (9) Pin sweep, repo-wide grep: 0 pins of the old semantics. No test deep-equals a stack refusal (stack.test.ts:54 toStrictEqual is on a returned stack), none reads a refusal's own symbol keys, and none asserts [] off a thrown refusal.

'--ran' answered: 'Run reconciliation — 83 derived, 83 run, 0 NOT-MEASURED, 0 UNRUN' ('a DERIVED zero — all 83 recorded an exit code and none of them is 3').

Four gates first answered PREREQUISITE NOT MET (exit 3): check:doc-formula-expressions, check:dual-build-cjs-loads, check:lean-entry-closure and check:type-check-debt.

    • Merged through the merge queue at 14:31:17Z.

    • Unblocks [finding] the conversions defineStack applies still miss two door paths after PR #20579: os lint --json never reads the record, and a defineStack that converts then refuses drops them from --json #20583 (domain:cli, its Blocked-by: #20618 in 5887096398). Its CLI half is the fold in the validate, compile / build and lint catch-alls, and triage's convert-then-refuse pin. The door reads it as conversions.push(...stackConversionsOf(error)). The ACCEPT carries one finding for that door's pin: the config loader must hand the refusal object to the catch-all itself, because a wrapping loader would drop the own-property record. ⛔ That card's state is its seat's to move; this record only reports the upstream closing.
