feat(rest): mount the compound-name per-item promotion door POST /meta/:type/:section/:name/publish (#11932)

[claude]

Fixes#11932

Mounts POST /api/v1/meta/:type/:section/:name/publish — the compound-name
arity of the per-item promotion door. Both arities now come out of one
two-entry registration loop, the same shape the ADR-0033 /published read twin
has carried since #7526.

Re-derived offsets — nothing reconciled to the order

Triage measured the promote door at rest-server.ts:5936 and the published
read at :6389. PR #11985 landed in this file afterwards, so both had moved.
Measured on origin/main at 1e79aa4f8, before any edit:

$ git rev-parse HEAD
1e79aa4f812708d5d097ca33d9b7040e02b958c6
$ grep -n "publish\`" packages/rest/src/rest-server.ts
3985: * `history`, `audit`, `diff`, `publish`, `rollback`, `published`, and the
6062: path: `${metaPath}/:type/:name/publish`, <- the promote door (was :5936)
6571: // :name/publish` now carries the caller's organization
$ grep -n "published\`\|publishedPath" packages/rest/src/rest-server.ts
6413: // Registered BEFORE the compound `/:type/:section/:name/published` <- the ordering trap (was :6291)
6509: for (const publishedPath of [
6510: `${metaPath}/:type/:name/published`,
6511: `${metaPath}/:type/:section/:name/published`, <- the two-arity read (was :6389)
6515: path: publishedPath,

Every one of the three had moved. After this PR (fef09c1e6): the two-entry
loop opens at rest-server.ts:6086, path: publishPath at :6092, the
compound-name assembly at :6262, and the new ledger row at
rest-route-ledger.ts:183.

The premise held — and it is the ROUTE that was missing, not the capability

Verified rather than relayed, driving the real
ObjectStackProtocolImplementation over a sys_metadata-backed engine against
a seeded compound draft, before this route existed:

STORE before: r_draft name=crm/task state=draft
PROMOTE compound -> {"success":true,"version":"sha256:382ea457ea0096…","seq":1,
"message":"Published draft — type=object, name=crm/task [seq=1]"}

publishMetaItem keys the draft on type/name/organization/package and reads the
name's spelling nowhere. The same measurement read the whole /meta mount table
off the real registered server and confirmed the asymmetry the card describes:
PUT and GET …/published mounted in both arities, POST …/publish in one.

An unplanned corroboration: client.meta.publishItemalready constructs this
URL — it interpolates the name unencoded and its own doc comment says
"Compound names pass through unencoded, like getItem". The SDK promised a door
the server had not mounted, and #3642's URL guard could not see it because the
compound name goes into the same ${name} slot the single-arity pattern
declares.

Route ordering — measured, and the honest shape of the constraint

The card names the first-match-wins trap. It is real for this pattern and it is
currently latent, and this PR states the difference rather than blurring it.

Measured against a real HonoHttpServer (resolveMountedRoute, the same
live-router observation the #7526 dogfood parity gate reads):

WRONG order: POST /meta/:type/:section/:name/:verb registered FIRST
resolveMountedRoute('POST', '/api/v1/meta/object/crm/task/publish')
-> { pattern: '/api/v1/meta/:type/:section/:name/:verb' }
live request -> {"answered":"sibling"} <- 200, wrong handler, no error
RIGHT order: the promotion door registered FIRST
live request -> {"answered":"publish"}
DIFFERENT arity: POST /meta/:type/:section/:name registered FIRST
-> { pattern: '/api/v1/meta/:type/:section/:name/publish' } <- cannot absorb it

So only a same-arity sibling can shadow this path. The live table has none:
the complete set of POST routes under /meta is _migrate-stored,
:type/:name/publish, :type/:section/:name/publish, :type/:name/rollback —
no POST catch-all exists, unlike the GET side where
GET /:type/:section/:name really does swallow its literal siblings.

That census is pinned as a list in meta-route-registration-order.test.ts,
so the day a POST catch-all is added the latent constraint becomes live and
this reddens. Reachability itself is probed against the live router rather than
inferred from a position in the table, and the wrong-order case above is in the
suite as the demonstration.

Anti-vacuity

• The real registered handler, over the real protocol. Every case resolves
  the door through RestServer.getRoutes() and drives it against
  ObjectStackProtocolImplementation over a sys_metadata-backed engine — the
  shape fix(rest): thread ?mode=draft on the compound-name metadata write door #11933's pins next door use.
• What the write DID, not the status. Every ⭐ case reads the STORE as
  [live label, staged label]: a promotion must leave the staged body LIVE and
  nothing staged (['Staged label', undefined]), and must leave the
  single-segment twin's rows untouched. A status-only pin cannot see The compound-name PUT /meta/:type/:section/:name never threads ?mode=draft, while its single-segment twin does — the fourth divergence closed, a fifth left open #11712's
  defect class.
• A literal-free door-to-door parity pin (§5) asserts the two arities agree
  on status, error code and store outcome across five request shapes without
  naming what they agree on, so a future move on either door reddens
  independently.
• The door can FAIL:404 when nothing is staged — the Three ledgered /meta routes are never mounted and die in the /meta/:type catch-all — the route audit can't see this class because it treats the ledger as ground truth for what's mounted #7526 disguise (a
  route that structurally cannot refuse) refused.
• The instrument produces a positive before its negative is trusted: the
  reachability probe is shown returning undefined for
  POST /meta/object/crm/task/rollback, a path this build genuinely does not
  mount — exactly what the publish path answered before this PR.
• The capability gate is enumerated, not assumed. The new door is registered
  in meta-write-door-capability-enumeration.test.ts's DOORS table, so
  The REST /meta publish and rollback doors carry no manage_metadata gate, so the authoring capability the PUT/DELETE doors enforce is reachable around #8919's 403-and-never-reached case now runs against it too. That table is
  the anti-drift assertion that caught this PR: adding a mutating /meta route
  fails the suite until the door declares its gate.
• The end-to-end lifecycle (§6): stage through
  PUT /:type/:section/:name?mode=draft, promote through the new door, read the
  edited body as live. That is precisely the sequence fix(rest): thread ?mode=draft on the compound-name metadata write door #11933's changeset told
  consumers was impossible.

Ablation — predicted vs measured

Revert onlypackages/rest/src/rest-server.ts to origin/main, keep every
pin, run. The mutation is confirmed on disk with anchored greps in both
directions before each leg, and the restore is confirmed byte-identical
(git diff HEAD = 0 bytes) — an editing tool's exit code is not evidence:

LEG A: RESTORED
'for (const publishPath of' : 1 [expect 1]
'path: `${metaPath}/:type/:name/publish`,' : 0 [expect 0]
-> Test Files 4 passed (4) · Tests 87 passed (87)
MUTATE (git checkout origin/main -- rest-server.ts)
'for (const publishPath of' : 0 [expect 0]
'path: publishPath,' : 0 [expect 0]
'const publishName' : 0 [expect 0]
'path: `${metaPath}/:type/:name/publish`,' : 1 [expect 1]
git diff HEAD bytes for that file: 28793
LEG B: ABLATED
-> Test Files 4 failed (4) · Tests 26 failed | 61 passed (87)
RESTORE
'for (const publishPath of' : 1 [expect 1]
git diff HEAD bytes for that file: 0

The 26 reds, per file:

file	red / total
meta-compound-publish-door.test.ts	14 / 15
meta-write-door-capability-enumeration.test.ts	7 / 45
meta-route-registration-order.test.ts	4 / 13
rest-write-response-internal-fields.tripwire.test.ts	1 / 14

No dist/ on the measured path for the ablated change. The suites import
RestServer from ./rest-server.js — a relative source import vitest compiles
from source — and packages/rest/vitest.config.ts aliases
@objectstack/plugin-hono-server to the sibling's src/. The ablation going
red is itself the proof: a dist-shadowed path would have stayed green. What
does resolve through exports to dist/ is @objectstack/metadata-protocol
(registered in check-test-source-alias.mjs's KNOWN_UNALIASED_TEST_IMPORTS
for this package) — nothing in this diff touches that package, so no rebuild
sits between the mutation and the reading; the dependency closure was built
once up front (pnpm --filter '@objectstack/rest^...' build).

Two predictions were wrong, and the corrections are the useful part.

1. rest-write-response-internal-fields.tripwire.test.ts was predicted green
   in both states — I read its disposition check as one-directional (a route
   with no entry fails). It is bidirectional: it also fails on a stale
   entry naming a route that no longer exists, so ablated my new key is stale
   and it goes red. Measured, not reasoned: predicted green-both-ways, observed
   red-when-ablated.
2. The first ablation round found a VACUOUS pin of mine.
   expect(stack.compoundPublish).toBeTypeOf('function') is true whether or not
   the route exists and passed the ablation. It is now
   expect(stack.mountedPublishDoors()).toEqual([SINGLE_PUBLISH, COMPOUND_PUBLISH]),
   read off the composed server's own table, and reddens when ablated
   (efd007b73). Round 1 measured 25 reds; round 2, after the fix, measures 26.

Green in both states — regression guards, ⛔ not red-before evidence:

• meta-compound-publish-door.test.ts §5 "and the twin is UNTOUCHED — its
  protocol request is what it always was" (the fence on the single-segment
  door).
• meta-route-registration-order.test.ts: "the single-segment spelling still
  resolves to its OWN pattern" (fence), "⭐ the instrument returns a NEGATIVE
  for a path this build does not mount" (the canary — green both ways by
  design: its job is to prove the probe can answer undefined), and the two
  synthetic-router cases ("shows what a wrong-place registration would do",
  "a DIFFERENT-arity sibling cannot absorb it") which register their own
  fixtures and never read rest-server.ts.

Clause ② — yes, and this is what it applies to

Mounting a route expands the public surface, so needs:contract-review is hung
on this PR. Concretely, what widened and what did not:

• Widened:POST /api/v1/meta/:type/:section/:name/publish answers where it
  used to reach the transport's notFound. 404 → 200/403/404 [no_draft]
  depending on the request.
• Not widened: nothing else. The two arities share one handler, so the new
  door inherits the manage_metadata gate (ADR-0066 D1), the ?package binding
  and its #6877 repeated-parameter refusal, the #7749 write-actor
  resolution, the organization scoping, the 404 [no_draft] answer and the
  501 envelope — each pinned. The single-segment door's request shape and
  answers are unchanged, asserted rather than assumed.
• No accept set narrowed anywhere, so no previously-accepted request is
  newly refused.
• No SDK change.client.meta.publishItem(type, name) already built this
  URL; it returned 404 for a compound name before and promotes after.

Also in this diff, and why

• packages/rest/src/rest-route-ledger.ts — the new mount must be ledgered:
  Three ledgered /meta routes are never mounted and die in the /meta/:type catch-all — the route audit can't see this class because it treats the ledger as ground truth for what's mounted #7526's parity gate asserts both directions, and an unledgered live mount
  fails it.
• .changeset/compound-meta-door-mode-draft.md — fix(rest): thread ?mode=draft on the compound-name metadata write door #11933's still-unreleased
  changeset carries a paragraph that says this promotion door does not exist.
  Both entries compile into one release, so left standing it would tell a reader
  in one paragraph that the door does not exist and in the next that it does.
  The paragraph is corrected in place, not deleted, and says so.
• content/docs/kernel/contracts/metadata-service.mdx — the one hand-written
  page that enumerates the metadata REST doors. Its prose said promoting a
  single item "is done via the /meta/:type/:name/publish route", which this
  change makes incomplete for a compound-named item. One sentence and one table
  row. No gate covers this class: node scripts/docs-audit/check-affected-docs.mjs
  exits 0 and reports the /meta ledger rows as unreachable for the SDK-route
  bridge (48 of 88 rows on rest-route-ledger.ts), so the drift check could not
  have named this page.
• scripts/engine-double-contract.pinned.json — the new suite's fake engine
  routes update/delete through the producer-side predicates, and
  check:engine-double-contract requires new pinned coverage to be recorded
  (--write, its own prescribed repair). Not a baseline raise: the ledger it
  grew is the RETAINED (pinned) one, not the DEBT one.
• packages/rest/src/rest-write-response-internal-fields.tripwire.test.ts — the
  The write-response internal-field tripwire walks the protocol class only — a direct engine write mouth outside it (rest-server's batch ql.update) is covered by the fix but not by the guard #8497 disposition table demands an entry for every write route. Green in
  both ablation states — a regression guard, not red-before evidence.

Verification

Every line below is the gate's own verdict line, captured on the final commit
efd007b73. Exit codes captured before any pipe.

Tests / types (@objectstack/rest, the only package this diff touches):

node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack — and
re-derived twice more as the change set grew (once when
scripts/engine-double-contract.pinned.json was added, which pulled in the
scripts/** families; once when the docs page was added, which pulled in ~14
docs families). All 40 derived local gates were run; the load-bearing verdict

its unit-level twin (meta-route-registration-order.test.ts) is in this diff.

📓 Docs Drift Check

This PR changes 1 package(s): @objectstack/rest, touching 11 documentable anchor(s).

18 hand-written doc(s) name something this change touched — list omitted above 15 rows. Re-derive on the tree named below: node scripts/docs-audit/affected-docs.mjs --json 399ecad58033006635b69d645b4df1d2091c98e5.

⛔ 4 release-owned page(s) also affected — read-only, see AGENTS.md Documentation Guardrails.

What this run could not see

• 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 — 13 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 399ecad58033006635b69d645b4df1d2091c98e5 → packageMentionDocs.

Which tree this was computed on

This run read content/docs from 6560a73a4d8a5dd242ff9768aceb4ed5cfea0d0a — the merge of head 2326dd5d4f882908f04f6bebbcf4849d445ee44b into base 399ecad58033006635b69d645b4df1d2091c98e5, which is what actions/checkout gives a pull_request run. Not the PR head.

A worktree cut from an older main holds a different content/docs, so re-deriving there can legitimately return a different list — that is a different tree, not a wrong row. To answer on the same tree:

# while this PR is open — GitHub drops the merge commit once it closes
git fetch origin 6560a73a4d8a5dd242ff9768aceb4ed5cfea0d0a && git checkout 6560a73a4d8a5dd242ff9768aceb4ed5cfea0d0a
# afterwards, rebuild it from the two parents, which stay fetchable
git fetch origin 399ecad58033006635b69d645b4df1d2091c98e5 2326dd5d4f882908f04f6bebbcf4849d445ee44b && git checkout -B drift-repro 399ecad58033006635b69d645b4df1d2091c98e5 && git merge --no-ff 2326dd5d4f882908f04f6bebbcf4849d445ee44b

⚠️ That checkout carried uncommitted changes, so the commit above does not fully identify what was read.

Advisory only, and a precision-first one (#9192): a page is listed because it names a
symbol, wire route or SDK method this diff touched — not because it mentions a changed
package. Each row says which anchor put it there, so a wrong row is reportable rather than
merely annoying. To re-verify, run the docs-accuracy-audit workflow scoped to these files:
node scripts/docs-audit/affected-docs.mjs 399ecad58033006635b69d645b4df1d2091c98e5 → pass the list as

check:objectql-double-limit — repaired by refusal, and why the gate list missed it

Pushed 2326dd5d4 (test-only, one file). CI's Lint & Repo Gates (job 97745771073) named this PR's own new suite:

packages/rest/src/meta-compound-publish-door.test.ts: NEW ObjectQL `find`
double that does not hold the caller's bound (1 blind, 0 breaking a shape
rule, 0 unjudged).
line 175: BLIND

Why the PR body's 40 derived gates did not include it

Not an oversight in the derivation — a structural blind spot worth recording. scripts/check-objectql-double-limit.mjs landed on mainafter this branch was cut, and scripts/pm/dispatch-gates.mjs derives families from the tree it is run in. Its own stderr says so: "gate list derived from the tree of 'objectstack-ai/objectstack' at commit efd007b". At that commit the gate does not exist, so no local derivation on this branch could name it. CI sees it because CI tests the merge with main. A local gate derivation on a branch behind main cannot see gate families that landed in between, and the gap is silent in both directions.

The remedy was measured, not picked

The gate prints two conforming exits: apply the bound by presence after the filter, or throw when handed a bound the double does not implement. Which is right turns on whether any caller in this suite passes a bound, so the double was instrumented at the seam and the suite run whole (15 cases):

	calls	shape
find	18	every one sys_metadata_history, keys ["where","context"], typeof o.limit === 'undefined'
carrying a bound	0	no call carries limit in any form
findOne	54	the control — proves the instrument records at all

The control is load-bearing: a first attempt probed through console.error, which vitest swallowed, and read zero for both. A zero with no control is not a reading.

So no caller passes a bound, and a slice() branch would be a line no case in this suite executes. Dead code cannot be relied on to be right on the day it finally runs. The throw states what this fake actually is — it does not implement paging — and turns the day some case starts handing it a bound into a RED rather than a quiet full scan that reads exactly like a passing test. It also matches this file's own idiom: match already throws on unsupported logical operators. Presence (!== undefined), not truthiness, so limit: 0 refuses too rather than being answered with the whole table.

Not a gate bypass

Refusal is a conforming exit the gate defines and self-tests ("the refusing fixture is CONFORMING"), for its own recorded reason: the defect class is SILENCE, not incompleteness. The baseline was not touched — it never grows — and no gate was skipped, relaxed or edited. The census moved in the one direction a genuine repair moves it:

before 77 apply the bound or refuse it loudly (0 refuse), 169 limit-blind
after 78 apply the bound or refuse it loudly (1 refuse), 168 limit-blind

The red was masking 46 more gates

The ESLint job runs its gates sequentially and the first failure aborts the rest. check:where-matcher sits at lint.yml:2568, before the failure at :2590, so it had run; the 46 gates after it had never run on this PR at all. The ones this change set can move were run here, all at 2326dd5d4, exit codes captured before any pipe:

exit 0 pnpm --filter @objectstack/rest typecheck
exit 0 eslint . --no-inline-config (full repo, 0 findings)

No other red surfaced.

Declared narrowing (one):check:type-check-debt --re-measure was not run. It re-runs tsc per ledger entry and packages/rest carries none — its only two mentions in scripts/check-type-check-coverage.mjs (lines 2668, 2887) are commentary — so this diff cannot move it. The structural half, check:type-check-coverage, was run and is green. This matches the PR body's existing note.

One further reading, recorded rather than acted on: the gate prints NOT verified: could not read the baseline at the merge base with main, because the baseline file does not exist at this branch's merge base. That check is unexercised locally for the same reason the gate was invisible; CI verifies it against the merge.

Unchanged: still draft, auto-merge not armed, needs:contract-review still hung on both carriers, PR body not rewritten.

⚠️ HOLD — supervening maintainer ruling under adjudication; ⛔ do not flip ready / enqueue / arm auto-merge

To the cli seat, from the PM session that cleared this PR's contract gate this morning (session_01H9StxQgG2DPA26XzZZqnJB): a maintainer ruling issued AFTER that clearance (2026-08-25, PM chat, verbatim: 「我认为斜杠不该存在」 · 「斜杠不该存在，现在就立卡…」) retires the compound-name convention this PR mounts a new door for — see #12176 (direction + phase-1 census, premise confirmed). Per the opposing-fact-during-ruled-implementation clause, the conflict is now a maintainer fork (recorded on #12176's report: land-vs-close), and this PR holds un-queued as the objection window until the maintainer answers. The morning approval is not revoked by this comment — it is suspended pending that answer; landing or closing follows the ruling, recorded here either way.

Closed by maintainer ruling — superseded by the name-grammar retirement (#12176)

Provenance (who / verbatim / where): the maintainer, PM chat session 2026-08-25 — direction ruling 「我认为斜杠不该存在」 · 「斜杠不该存在，现在就立卡，你负责派发，然后给我结果」, then the land-vs-close fork was presented with the full four-axis analysis and the maintainer accepted the recommendation (close): 「我看到你的意见了，我同意」. Recorded by PM session session_01H9StxQgG2DPA26XzZZqnJB.

Grounds, from #12176's phase-1 census (all measured, each zero beside a firing control): zero producers construct a compound name anywhere in the repo, zero stored rows carry one — this door's only traffic is test traffic. Mounting a fourth compound door in the week the convention is ruled retired would hand D3 a fourth retirement and hand AI authors a fresh documented invitation to the exact shape D1 will refuse. The morning contract-gate clearance on #11932 was made under the old convention and is superseded, not faulted.

The engineering in this PR is not lost: the route-shadowing measurements, the capability-enumeration table pattern, and the door-to-door parity pin shape are recorded on #11932 / #12106 / #12176 and will be reused by D3 (which retires the remaining compound arities and resolves all five broken SDK methods at once). publishItem's compound-name 404 remains the status quo until D3 — #11932 is re-parked accordingly.
