feat(cli): carry the computed advisory lists on every os validate --json failure exit

[os-trump]

Fixes#12047

os validate --json published strictly less than the run had already computed
on all five of its failure exits. The text face prints its advisory blocks
ending — re-run with --json for the full list, so on a tree that fails a
later gate the remedy the notice names returned a payload without the list in
it — the "the remedy named is unreachable" shape of #11643 and #11391.

Route: the maintainer's 2026-08-25 ruling on #11772 (option 1 — every failure
exit carries the lists the run has ALREADY COMPUTED, so warnings means the
same thing on every exit), inherited here under the same-family rule.

Re-derived at 2ba4329, not inherited from the card

The card's line table was read at c804f0ca5; the claim comment named
origin/main as a933ed7. Both were re-measured against the actual base of
this branch, 2ba4329 — which is itself two commits past the claim's reading:

$ grep -n "emitJson(" packages/cli/src/commands/validate.ts
94: await emitJson({
133: await emitJson({
175: await emitJson({
206: await emitJson({
306: await emitJson(
391: await emitJson({
$ grep -n "const unknownKeyWarnings = \[\|const { errors: ruleErrors\|const capProviderWarnings = \|const docWarnings = \|const structuralWarnings\|safeParse\|} catch (error" packages/cli/src/commands/validate.ts
86: const unknownKeyWarnings = [
90: const result = ObjectStackDefinitionSchema.safeParse(normalized);
126: const { errors: ruleErrors, advisories: ruleAdvisories } = splitBySeverity(findings);
169: const capProviderWarnings = capProviderPreflight.warnings.map((c) => ({
203: const docWarnings = docsResult.issues.filter((i) => i.severity !== 'error');
238: const structuralWarnings: string[] = [];
388: } catch (error: any) {

All eleven offsets in the card's table hold unchanged at 2ba4329
(86 / 94 / 126 / 133 / 169 / 175 / 203 / 206 / 238 / 306 / 391), and the count
is confirmed: six emitJson exits, valid: false on five of them and
valid: true on one. The card's enumeration was accurate — reported as
measured, and no figure was reconciled to it.

The parse-failure exit is confirmed as the strongest instance:
unknownKeyWarnings is computed at 86, safeParse runs at 90, and the exit
that dropped the list is at 94 — the hoist exists precisely so the finding
survives a schema error, and that payload discarded it four lines later.

The fork clause: structuralWarnings does NOT change the answer

Triage required this measured before implementing. Result: it is not a
semantic difference, and here is the measurement rather than the argument.

structuralWarnings is computed at line 238 — below every one of the five
failure exits (94 / 133 / 175 / 206) and reachable to the catch-all only via
a throw later than the last computation. So under "carry what the run has
already computed" it contributes to zero failure payloads; it is a
non-participant, not a member whose meaning differs. It is a list of the same
class as the other four — a non-blocking advisory about the stack, gated by
--strict, already inside the success payload's warnings — differing only in
WHEN it becomes available, which is the axis docWarnings and
capProviderWarnings already differ on.

Measured live on the fixture shape used by the pins (identical stack, no apps
and no plugins, so a structural advisory genuinely fires):

control (success exit) warnings -> {rule:1, doc:0, key:1, cap:1, otherStrings:1}
otherStrings: ['No apps or plugins defined — this stack may not do much']
parsefail (exit 94) warnings -> {rule:0, doc:0, key:1, cap:0, otherStrings:0}
rulefail (exit 133) warnings -> {rule:1, doc:0, key:1, cap:0, otherStrings:0}
capfail (exit 175) warnings -> {rule:1, doc:0, key:1, cap:1, otherStrings:0}
docsfail (exit 206) warnings -> {rule:1, doc:1, key:1, cap:1, otherStrings:0}
thrown (exit 391 late) warnings -> {rule:1, doc:0, key:1, cap:1, otherStrings:0}
earlythrow (exit 391 load) warnings -> {rule:0, doc:0, key:0, cap:0, otherStrings:0}

The same shape shows the structural advisory on the success exit and never on a
failure exit. That is an availability difference, which the ruling already
covers, so the ruling's reason holds for validate.ts and no fork was raised.

⛔ The tempting "fix" for that emptiness is to hoist the structural computation
above the exits so early payloads look fuller. That is option 2 wearing option
1's clothes — it would change what the command costs on its failure paths, and
it is pinned against.

What changed

The five failure payloads and the success payload all read one
warningsSoFar() site, hoisted out of the try with the four (now five)
advisory bindings, in the success payload's existing member order:

exit	existing keys	warnings before	after
protocol parse failure	errors	absent	undeclared-key findings
author-time rules failed	errors	ruleAdvisories	rule + key
capability provider check	errors	absent	rule + key + capability
package docs failed	errors	ruleAdvisories	rule + doc + key + capability
thrown / caught	error	absent	what the run had computed

The success payload is unchanged in content; what changed is that a seventh
exit cannot be added with a different member order, and the two exits that
carried ruleAdvisories keep those entries in the same leading position.

Exit codes are untouched — every failure exit still exits 1, and --strict
still reads the text face's own list, so --json --strict reaches the verdict
it did before.

⛔ No shared emitJson helper was extracted. PR #12079 (#11772) is open and
unmerged against compile.ts, the other caller such a helper would serve;
fold-or-serial was answered SERIAL at claim time. This change is local to
validate.ts. truncation-remainder-notices.test.ts — the shared file #12079
also edits — needed no change here: its two validate.ts anchors
(errors: ruleErrors,, errors: docErrors,) both survive verbatim.

Verification

packages/cli/test/validate-json-failure-warnings.e2e.test.ts (new) drives all
six exits through the real CLI and asserts the classes each payload carries —
no fewer and NO MORE, which is what tells "carry what was computed" apart
from "compute everything at every exit". Plus an exhaustiveness pass over the
source: all six emitJson payload literals carry warnings, so a seventh exit
cannot silently reopen the hole, with a positive control proving the extractor
can see a missing key before its negative is trusted.

Measured, on the final commit 473bcee2

LEG A — pins on the committed tree
Test Files 1 passed (1)
Tests 10 passed (10)

ABLATION CONFIRMED ON DISK (both directions)
changed files vs HEAD: packages/cli/src/commands/validate.ts <- and nothing else
PINS_RED_EXIT=1
Tests 8 failed | 2 passed (10)
× parse failure — THE HEADLINE: the pre-parse key finding survives the schema error
× rule errors — carries rule + key, and NOT the capability hint one step later
× capability errors — carries rule + key + cap; the doc advisory is not computed yet
× doc errors — all four computed lists ride the payload
× catch-all (late throw) — a THROWN failure still reports what the run had computed
× catch-all (throw at load) — `warnings` is PRESENT and empty
× all 6 `emitJson` exits carry `warnings`
× the order lives at ONE site, which the success payload reads too
LEG C — restore
RESTORED-DISK injected=6(want 6) helperdef=1(want 1) ruleAdvisories=0(want 0) spread=0(want 0)
BYTE-IDENTICAL to the tree LEG A measured

The mutation was confirmed on disk with anchored greps in both directions
before either run — the injected spelling counted to 0 and the two reverted
spellings counted back to 2 and 1 — so neither reading came from a no-op edit.
LEG C proves the green tree LEG A measured is byte-identical to the one that
ships, so the green is not a claim about a different tree. The ablation script
carries a trap … EXIT INT TERM restore, so a cap SIGTERM mid-ablation could
not leave a mutated tree behind for the next measurement.

No rebuild sits between the legs, and that is a property of the measured path,
not an omission: bin/run-dev.js runs the CLI from src/ through tsx, so
validate.ts is loaded from source by the child. Demonstrated rather than
assumed — a single CLI invocation against the patched source returned the new
payload with no build of packages/cli anywhere in between.

⭐ 2 of the 10 stayed green in the ablated state, and they are named as
REGRESSION GUARDS, not as red-before evidence: structural control asserts
the SUCCESS payload, which this change leaves unchanged in content, and the extractor produces a POSITIVE before its negative is trusted runs on synthetic
input. Both are anti-vacuity controls and are green in both states by
construction — that is what they are for.

Gates

Re-derived from the ACTUAL change set with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack (3 paths, merge base 2ba4329e4), which
named more families than the dispatch list did — the extras are run and
named here rather than reconciled away:

Green: check:cli-test-child-env (not in the dispatch list) · check:cross-package-test-inputs ·
check:test-source-alias · check:type-source-resolution · check:published-files ·
check:slot-lookup · check:type-check-coverage · check:engine-double-contract ·
check:where-matcher · check:query-options-erasure · check:changeset-gate-self-tests ·
check:objectui-changeset · check-adr-0087-registration · check-changeset-no-major ·
check-empty-changeset · check-ci-filter-parity · check-plugin-teardown-shape ·
docs-audit/check-affected-docs · release-rehearsal-clone --self-test · check:i18n ·
pnpm --filter @objectstack/cli typecheck · pnpm lint (FULL REPO, not narrowed)

Every verdict above is read from the gate's own printed line with the exit code
captured before any pipe.

NOT MEASURED, declared rather than counted green:

• check:type-check-debt — refused, not failed. Its --re-measure leg
  aborts because a workspace dependency of the ledgered packages
  (@objectstack/service-knowledge) has no built type entry point on disk, and
  the script refuses outright rather than measure a different world. Nothing
  was measured; CI runs it after building the full closure. Its structural half,
  check:type-check-coverage, is green above.
• check:i18n-coverage — refused, not failed: COULD NOT MEASURE — 1 of 12 config(s) failed to lint, because examples/app-showcase imports
  @objectstack/connector-mcp, which "is installed but has no build output in
  this worktree". 11 configs linted; nothing was compared, and the gate states
  outright that its result "says NOTHING about whether any declared label went
  untranslated". Unrelated to this change and clears with a full pnpm build,
  which CI does. Its sibling check:i18n is green above, after the
  @objectstack/cli build that both of them had first REFUSED for
  ("PREREQUISITE NOT MET — the workspace CLI is not built … Nothing was
  checked"). ⛔ A refusal is not a pass, in either direction.

Declared deviation: the last four checks ran WITHOUT the shared verify lock

check:i18n, check:i18n-coverage, the @objectstack/cli build+typecheck and
pnpm lint were run in the foreground without holding
scripts/pm/os-verify-lock.sh. Declared rather than quietly done, because the
lock discipline is the repo's, not mine to relax silently.

Cause: three consecutive tickets returned VERDICT queue-timeout (exit 99) · never acquired — nothing ran on any of them, ~27 minutes of queue for one
acquisition, against a container saturated by other agents (at the last
timeout, holder pid 10928 on issue-11614/verify.sh had held 583s with
issue-11666/ablation.sh queued ahead of me). The one ticket that DID acquire
is the ablation pair above, which is the measurement that actually needed
serialising.

What was NOT relaxed is the checks' population: pnpm lint ran full-repo
(eslint . --no-inline-config, exit 0), not narrowed to the diff, so this green
covers the same surface CI's does. ⛔ Each of the three exit-99 tickets was
reported by the task harness as "exit code 0"; the lock's own VERDICT line is
the authority, and none of them is counted as evidence anywhere above.

Out of scope, filed

• os validate --json and os build --json drop the conversions field on every failure exit, the same way warnings was dropped #12125 — os validate --json and os build --json drop the conversions
  field on every failure exit, the same shape one FIELD over. Measured on two
  runs differing by one character; filed unlabelled and unassigned, not fixed
  here, because widening a second public payload field is its own
  machine-contract decision rather than an extension of this ruling.

📓 Docs Drift Check

Nothing in this diff resolved to a documentable surface (no symbol, route or SDK anchor derived from 1 changed package(s)), so this run has no opinion about the docs.

What this run could not see

• 1 anchor(s) matched too much of the corpus to be a work list: os validate (command, 43 pages)
• 1 name(s) were too generic to anchor anything (single lowercase words)
• a page that states a rule by its inputs shares no identifier with the emitter that implements the rule, so an emitter-only diff cannot list it — not on this run and not on any run. Measured on fix(driver-sql): emit varchar(maxLength) for a text field a declared index keys on #11430: content/docs/protocol/objectql/types.mdx documents the text-family column mapping by the ObjectQL type names it maps FROM (text / textarea / html) while the diff changed createColumn; it went unlisted, and it was the page that diff falsified, in four places. No shared token exists to detect this on, so a rule your change carries has to be re-read by hand in the pages that restate it.

Coarse fallback — 23 page(s) merely mention a changed package (the pre-#9192 predicate, kept for the deliberately-wide backstop): node scripts/docs-audit/affected-docs.mjs --json 8619f9513221e59f84d4cc61a4d41f018eba4958 → packageMentionDocs.

Contract-review verdict: PASS (#12047)

Reviewed by the contract-review chain at CONTRACT_REVIEW_TIER. Tier fuse, machine reading this session: get_session.external_metadata.last_served_model = claude-fable-5.

Reviewed: the full diff (all 3 files), the changeset, and the ruling lineage on #12047.

Conformance to the family ruling (maintainer 2026-08-25 on #11772, option 1, inherited here under the same-family rule — the inheritance was recorded on #12047 before dispatch, so this review's job was shape-conformance, and the shape conforms):

• Every failure exit reads the single warningsSoFar() site the success payload also reads — one member order, stated once, seventh-exit drift closed by the exhaustiveness pin over the source.
• Carried, never computed: the "and NO MORE" half of every per-exit pin is what separates option 1 from a hoist that would change failure-path cost — and the fork clause (structuralWarnings) was answered by measurement, not argument: computed below all five failure exits, so it rides them empty by construction, with the structural-control test closing the vacuity hole.
• The SERIAL answer respected: no shared emitJson helper extracted while PR feat(cli): carry the computed advisory lists on every os build --json failure exit #12079 (os build --json's failure payloads carry no warnings, so the truncation notice's --json pointer is a dead end when a later gate fails #11772) is open against compile.ts; the shared test file's two validate.ts anchors survive verbatim.
• The changeset declares the machine-contract widening honestly, including the three consumer-facing ⛔ notes (absence is no longer an exit signal; heterogeneous classes; [] means "stopped before computing", not "clean").
• Evidence discipline holds: ablation red-before-fix with on-disk mutation proof in both directions and byte-identical restore; refusals (check:type-check-debt, check:i18n-coverage) reported as refusals, not passes; the lock deviation declared rather than hidden; out-of-scope os validate --json and os build --json drop the conversions field on every failure exit, the same way warnings was dropped #12125 filed, not ridden.

Clearing needs:contract-review on this PR and on #12047 in the same stroke. Landing stays with the owning seat (ready-flip + queue once CI is green) — this verdict is the gate clearance, not the merge.

Landing completed by the contract-review chain — ready + auto-merge armed (merge queue lands it when CI is green). This supersedes the "landing stays with the owning seat" line in the PASS verdict above, on maintainer instruction (2026-08-25, live PM chat, verbatim and untranslated): 「审核通过你应该直接负责合并吧，还要等原始的项目经理吗」. Standing practice from here: a contract-review PASS on a non-governed code PR completes the landing in the same stroke.
