spec(stack): a refusing defineStack carries the conversions it applied on its StackRefusalError, so the doors can report them (the spec half of #20583) #20618
Description
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:headerdescription, noticepage-header-subtitle-alias) and then refuses (requires: ['no-such-capability']) exits 1 withSTACK_CAPABILITY_UNKNOWNandconversions: []onos validate --json,os build --jsonandos lint --json. The notice reaches stderr only.- Stderr capture is lossy.
warnConversionNoticewarns once per process. OncomposeStacks([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 lackssurface,toMajor,codeandmessage. - Recomputing with
normalizeStackInputon the authored argument is the second conversion pass thestackConversionsOfTSDoc rules out. - No hook exists. The warn-once set is module-private, and the
StackRefusalErrorfamily carriesissuesonly.
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
StackRefusalErrorthatdefineStack's strict tail throws, under the sameSymbol.for('objectstack.stack.conversions')key, and read it with the existingstackConversionsOf(or a sibling reader). - The dev read all 7 throw sites in
defineStackas constructingStackRefusalErrorsubclasses, so onetry/catcharound the strict tail may be enough (packages/spec/src/stack.zod.ts,stack-provenance.ts). - Amend the
stackConversionsOfTSDoc 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
- The CLI fold in the three catch-alls (
validate,compile/build,lint), one line each. - Triage's convert-then-refuse pin.
- [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 1 (
os lint --jsonfoldsLoadedConfig.stackConversions) ships on its own in PR fix(cli): os lint --json reports the ADR-0087 conversions defineStack applied #20617, which saysPart of #20583. [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 waits on this card for location 2.
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.

"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.
