fix(service-messaging): the durable fan-out refuses an unregistered channel instead of writing a delivery row that can only dead-letter

[claude]

Part of #18050

Clause-②: no

Re-derived from the delivered diff, with the control, below.

⚠️ Read this first: the card has two halves and this PR lands ONE of them. The
dispatch asked for a closing keyword; the body deliberately does not carry one, because
fork 2 is answered but not implemented. The PM should close the card by hand once it has
read the fork-2 measurement below, or re-dispatch that half. Everything in the "What was
NOT done" section is a measurement, not a shortfall of effort.

What was wrong

MessagingService.emit() has two fan-out paths. The inline P0 path (fanOut) has always
refused a channel nobody registered: no send(), one failed DeliveryOutcome per
(recipient × channel), error: channel '(id)' not registered. The durable P1 path
(enqueueDeliveries) had no registration check at all — its two loops contained no
channels.get, no channels.has, no refusal — so it wrote one sys_notification_delivery
row per recipient, and NotificationDispatcher dead-lettered every one of them on attempt
one (processRow and processDigestGroup both ack dead: true the moment
getChannel() answers nothing).

That is #17732's reported symptom: a row that exists only to die. Ruling 5644350987
structurally cannot reach it — isAvailable() is a member of a channel IMPLEMENTATION,
and an unregistered channel has none to ask.

What this PR does — fork 1, the "refuse" side

enqueueDeliveries now checks registration before it enqueues. An unregistered channel
gets no row and the caller gets the same failed DeliveryOutcome the inline path
already produced, so "nothing was sent and here is why" reads identically whichever path
served the emit. EmitResult.failed counts them; enqueued and delivered do not, so no
summary can claim work that never existed.

The refusal is logged once per channel per emit, carrying the number of rows it
refused and the remedy — not once per recipient. The durable path is the high-volume one:
a 500-recipient audience on one missing channel must not print 500 identical lines, and
the count is what sizes the misconfiguration.

⛔ Why it is NOT recorded in sys_notification.suppressed_channels

CHANNEL_UNAVAILABLE_REASONS is documented on the seam as "Why a channel is not
available for a tenant" — every value is a column value an operator filters and
reports on. An unregistered channel is a composition fact: identical for every tenant
in the process, and fixed by mounting the channel, not by configuring the tenant. Folding
it in would make a per-tenant report assert a deployment-wide misconfiguration.

It is also the fence #18041 settled, from the other side. Recording it would need a new
literal in that closed set, which channel-availability.test.ts holds byte-equal to the
copy inlined on sys-notification.object.ts — i.e. an edit in packages/platform-objects,
which is domain:engine and not this card's. Both reasons point the same way, and the
suppression key stays written only when something was actually suppressed, so the
common path's column set is unchanged (pinned again here, by enumeration).

What was NOT done — fork 2, and why. Two measurements.

1. The card's stated mechanism for fork 2 is falsified. The card reads
messaging-service-plugin.ts:261-268 as AGENTS.md's "Startup registry reads" three-part
shape, on the grounds that "an email service that registers later never gets its
channel". Measured on this tree:

• ObjectKernel.use() throws Cannot register plugins after bootstrap has started
  whenever state !== 'idle' (packages/core/src/kernel.ts:240-243), so no plugin joins
  the composition after boot begins.
• Both providers register their service in init(), not later:
  plugin-email/src/email-plugin.ts:430 and service-sms/src/sms-plugin.ts:214.
• kernel-base.ts:291 states the contract directly: kernel:ready is "the only correct
  moment for a plugin to assert that the preconditions it declared were actually met (the
  registries are still filling during init())" — i.e. the service registry is no longer
  filling at kernel:ready.

⇒ Part 1 of the three-part shape ("a read of a registry that is still filling") does not
hold at that call site, so the rule does not reach it. What is live is narrower and does
not need a registry argument: a deployment with no email plugin simply has no email
channel, and its flows notifying on ['inbox','email'] take the path this PR just fixed.

2. The obvious cure for fork 2 is unsafe until a parked defect is fixed first. Cure 1
in that section ("resolve where it is used") maps cleanly here: register the email channel
unconditionally and let isAvailable() — which already reads opts.getEmail() live at
email-channel.ts:238 — answer transport_not_configured. That would convert this whole
class into ruling A's suppression shape, with the audit trail, and is clearly the better
end state. But it also widens the reachability of the defect the card parked:

• email-channel.ts:252 returns { ok: true } when no email service is present
  ("capability not installed — no-op"), and sms-channel.ts:151 does the same. The SMS
  channel has no isAvailable at all.
• Today, with no email service, the channel is absent ⇒ the dispatcher dead-letters the
  row: wrong, but loud.
• Register it unconditionally and the dispatcher instead calls send() ⇒ { ok: true } ⇒
  the delivery row is acked sent, with nothing sent. That is a durability lie and a
  strictly worse shape than the one being fixed.

⇒ Fork 2 needs send() to stop reporting success for an absent transport first — which is
a retry-semantics change (classifyError, permanent vs retryable) with its own pins, and
the card explicitly parked it. Routing that is the PM's. ⛔ No unconditional registration
in this PR.

Clause-② — re-derived from the DELIVERED diff, with a discriminating control

The delivered diff adds no published declaration and no accepted value.

Only one changed file ships at all (files: ["dist","README.md","CHANGELOG.md"]; the two
test files and the changeset never leave the repo). In that file, every added non-comment
line lives inside the body of a private method, and TypeScript emits private members
with no signature:

packages/services/service-messaging/dist/index.d.ts:2048
    private enqueueDeliveries;

The probe, and the control that proves the probe can see a real export — run against
the freshly built dist/index.d.ts:

CONTROL (known-published exports, must be non-zero)
  CHANNEL_UNAVAILABLE_REASONS    5 hits   ChannelSuppression   3 hits
  DeliveryOutcome                5 hits   EmitResult           3 hits
  MessagingChannel              17 hits
PROBE (identifiers this diff adds)
  unregistered-channel           0 hits (d.ts)   0 hits (index.js)
  channel_not_registered         0 hits (d.ts)   0 hits (index.js)

The word refused does appear 10× in the published .d.ts — 9 of them predate this
branch and the 10th is the new doc comment; none is a declaration
(grep -E '^\s*(export|declare|type|interface|const|function|class).*refused' is empty).

And the negative is about the accept set, not about reach: the new behaviour does ship
(dist/index.js carries the new warn text, 1 hit), which is what makes the zeros above
informative rather than a probe that simply cannot see anything.

⇒ Clause-②: no. No member was added to a published interface, no value was added to a
published enum, no key was added to a published payload. A patch changeset is therefore
the correct grade, not the minor a yes would require.

Recovery round — the Test Core (6/6) red, its root cause, and the fix

The previous push left Test Core (6/6) failing. The shard log shows
check-test-completeness: @objectstack/plugin-auth was scheduled but never reached
and the same for @objectstack/downstream-contract — 1 of 3 scheduled packages
reported, 2 never reached.

⚠️ That "never reached" line is a CONSEQUENCE, not the cause. The shard runs
turbo, turbo stops on the first failing task, and the two packages behind the
failing one never got to run. ⛔ It is not a flake and nothing was skipped,
disabled or quarantined to clear it.

Root cause — a cross-package pin this branch's own producer change falsified.

FAIL packages/services/service-automation/src/builtin/notify-delivery-outcome.integration.test.ts
  > notify run summary vs. the durable delivery record (#7747)
  > does not report a countable act for a delivery that dead-letters on an unregistered channel
AssertionError: expected [] to have a length of 1 but got +0     (line 122)

That file is on origin/main (landed by #7875 for card #7747) and this branch
never touched it. Its first case boots WITHOUT push registered and asserted,
as its scenario setup, that the durable fan-out wrote one delivery row and the
dispatcher dead-lettered it:

expect(rows).toHaveLength(1);
expect(rows[0].channel).toBe('push');
expect(rows[0].status).toBe('dead');

Those three lines describe exactly the defect #18050 filed. This PR removes
the row, so the pin that recorded the row had to move with the producer.

Why the inherited push did not see it. The producer package's own suite is
green (460/460) and always was — the contradicting pin lives in a CONSUMER
package, and service-automation resolves @objectstack/service-messaging
through dist/ (its vitest aliases only @objectstack/platform-objects), so
nothing in the producer's own lane could surface it.

The fix — re-pinned, ⛔ not relaxed. notify-delivery-outcome.integration.test.ts
now asserts the new producer contract:

	before	after
outbox after dispatcher.tick()	1 row, status: 'dead'	0 rows
run summary	acted: 0, unmeasured: 1	selected: 1, acted: 0, unmeasured: 0
the #7747 invariant acted <= non-dead rows	bound was 0-non-dead	bound is now 0 rows at all

The unmeasured 1 -> 0 move is the point, not a relaxation. unmeasuredEffect
means "the count is unknown because the dispatcher decides later"; since this PR
there is no later — the refusal is synchronous, so the count is KNOWN and it is
zero. That is the reading notify-node.ts states in its own words:

⛔ The fix is NOT to report the zero as unmeasuredEffect. That flag means
"the count is unknown", and this count is known and it is zero; claiming
otherwise would take the run OUT of the broken-sweep filter
(selected > 0 AND acted = 0 AND unmeasured = 0) — the platform's own alarm
for a green-but-inert sweep — on precisely the run that should be inside it.

So the durable path now lands where the inline path already was: the fourth case
in that same file asserts this identical triple and calls it "correctly eligible
for the broken-sweep alert". Making the two fan-out paths agree is what this card
set out to do, and the consumer pin is where that agreement becomes observable.

The tick is deliberately kept in the updated case: it proves nothing APPEARS
later either, which is strictly stronger than the old "a row exists and is dead".

Independent judgement of the inherited work

The inherited diff was re-read and judged rather than extended:

• The refuse side of fork 1 is right, and is kept. The registration check
  mirrors the inline path's existing one, the failed DeliveryOutcome is the
  same shape, and notify-node.ts's own stated design is what makes the
  resulting acted: 0, unmeasured: 0 the correct answer rather than a loss of
  signal. ⛔ Nothing about the suppressed_channels reasoning was reversed.
• One real gap, now closed: the behaviour change has cross-package
  consumers and only the producer package was run. The consumer set was
  enumerated from the manifests (cli, dogfood, example-showcase,
  plugin-auth, plugin-webhooks, runtime, service-automation) and the
  affected ones were run — see Evidence.
• scripts/engine-double-contract.pinned.json is NOT in this diff (0 hits
  over the whole branch range), so this card does not join the live serial relay.
  check:engine-double-contract exits 0.

Evidence — this round, measured on a3950e4fa

⚠️ Every reading below was taken on a BUILT closure. service-automation
consumes service-messaging through dist/, so a run on an unbuilt tree
measures nothing. Closure build: pnpm --filter '@objectstack/service-automation^...' build
:: VERDICT command-exit 0.

Reproduction, then the fix

before  vitest run src/builtin/notify-delivery-outcome.integration.test.ts
        Test Files 1 failed (1) · Tests 1 failed | 3 passed (4)
        AssertionError: expected [] to have a length of 1 but got +0

package	files	tests

@objectstack/service-messaging	43	460 passed

The two packages the aborted shard never reached — run here because a shard
that stops early cannot be read as "the rest passed". VERDICT command-exit 0:

package	files	tests
@objectstack/plugin-auth (also a direct consumer)	110	2340 passed
@objectstack/downstream-contract	3	31 passed

Typecheck — VERDICT command-exit 0 for both affected packages.
check:test-typecheck reports service-automation's test layer compiles under
tsconfig.test.json, 0 files / 0 errors, and tsc -p tsconfig.test.json --listFiles puts the edited file in the program (1 hit) — so the green is
attributable, not the "typecheck excludes *.test.ts" false reading.

Reverse verification (ablation) — direction predicted RED, observed
RED, and it fails on the NEW assertion, so the updated pin is discriminating
rather than vacuous. The guard block was deleted from the committed producer
source, the producer was REBUILT (the consumer reads dist/), and the mutation
was proven to have reached the artifact before the colour was read:

anchor before mutation   grep -c 'if (!this.channels.has(channel))' = 1

RESTORED RUN             Tests 4 passed (4)

The script installed a trap on EXIT, INT and TERM calling a restore function,
restore is proven by STATE (blob equality plus a whole-tree
git status --porcelain), never by an exit code.

Acceptance notes — observed, not filed, not fixed here

• fanOut logs its "not registered" warn once per (recipient × channel) pair rather than
  once per channel per emit. Same noise shape this PR avoided on the durable path; the
  inline path is the low-volume one, so it is left alone rather than widened into scope.
• email-channel.ts:252 / sms-channel.ts:151 returning { ok: true } for an absent
  transport is already recorded on [finding] The outbox fan-out writes a delivery row for a channel that is NOT registered — #17732's reported symptom, which ruling A does not reach #18050's body. It is not filed separately here so that
  the card's own record stays the single home for it — which is the second reason this PR
  does not carry a closing keyword.
• sms-channel.ts implements no isAvailable, so the SMS half of ruling A is unrealised.
  In-lane, but it only becomes useful together with fork 2, so it belongs to that routing.
• The consumer pin this round repaired lives in service-automation, not in
  this card's landing package. It is in-lane (domain:services) and was owed by
  this diff's own behaviour change, so it is fixed here rather than filed.
• sms-channel.ts still implements no isAvailable, and email-channel.ts:252 /
  sms-channel.ts:151 still answer { ok: true } for an absent transport. Both
  are already recorded on [finding] The outbox fan-out writes a delivery row for a channel that is NOT registered — #17732's reported symptom, which ruling A does not reach #18050's body; noted, not filed, so the card stays the
  single home for them.
• This branch is 2 commits behind origin/main. No merge was taken in this
  round: the queue rebuilds the PR as merged and re-runs the required contexts
  on that generation, which is the reading that decides.

📓 Docs Drift Check

This PR changes 1 package(s): @objectstack/service-messaging, touching 2 documentable anchor(s).

⛔ 1 release-owned page(s) name something this change touched. These are read-only:

• content/docs/releases/v17/17-2.mdx (via MessagingService (symbol, a top-level class))

content/docs/releases/ is RELEASE-OWNED (AGENTS.md "Documentation Guardrails"): release
notes are written centrally at release time, and a code PR that edits them is the exact PR
that guardrail exists to stop. They are still audited — read-only. If one of them is actually
wrong, file an issue or open a dedicated docs-only PR; do not edit it here.

What this run could not see

• the SDK route bridge reached 60 of 215 client-bound route-ledger rows — the other 155 have no registrar path: tail to select them, so pages documenting THEIR client methods cannot appear above, on this or any run. Of those 155: 0 are remediable by widening that discovery convention (an in-repo file declares the path; the convention did not scan it); 55 are structural — on a ledger where NOT ONE row is declared in-repo, so no discovery change reaches them at any price; 100 are undecided (no in-repo declaration, on a ledger that has other in-repo registrars — absence and an unreadable spelling are not distinguishable here). The rows themselves: node scripts/docs-audit/affected-docs.mjs --bridge-coverage
• 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 — 5 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 57343f761cbd45e2049cd27a3487495dab2c8b1b → packageMentionDocs.

Which tree this was computed on

This run read content/docs from 61a56423f56bc582bc4870d1b19c1dc27d4e1e60 — the merge of head a3950e4fa78fdf7b43582951070cbb139bf089d6 into base 57343f761cbd45e2049cd27a3487495dab2c8b1b, 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 61a56423f56bc582bc4870d1b19c1dc27d4e1e60 && git checkout 61a56423f56bc582bc4870d1b19c1dc27d4e1e60
# afterwards, rebuild it from the two parents, which stay fetchable

⚠️ 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

merely annoying. To re-verify, run the docs-accuracy-audit workflow scoped to these files:

PM note — part of the Check Changeset red was my label, and it is cleared. ⛔ Don't chase it.

What I changed (the PM owns the carrier, not you):

needs:contract-review is stripped from both carriers — this PR and card #18050 — and card #18050 now carries a Clause-②-correction: 5656739436 declaring Clause-②: no.

The claim's yes was a prediction, and your delivery falsified it. Re-derived at 1a20442146…, with a control:

probe	reading
added export lines in the diff	0
new symbol reachable from the published entry	none — the additions are a function-local Map and its loop
{ ok: false, error: … } a new key?	no — ⭐ that shape already exists on main in this same file at :1127, :1129, :1217-1218, :1230, :1236-1237. You reuse DeliveryOutcome; you do not add a key

⭐ And your docblock settles the one thing that would have made it yes: suppressed_channels answers "why can this tenant not send", while an unregistered channel is a composition fact. Declining to fold it in is what keeps clause ② standing down. That reasoning is better than the prediction my claim made — recorded so it is not re-litigated.

check-clause2-carriers --pair 18081 now exits 0.

Why the red may still look stale: the Check Changeset runs at 23:45/23:46/23:48 all predate the carrier strip, and the one at 23:48:48 ran before it. The gate re-reads the declaration on the next edited event and states it clears "with no push and no re-run" — so ⛔ do not push anything for that check alone; your next push for the real failure will re-trigger it with both the strip and your line-anchored Clause-②: no in place.

Still yours, and ⛔ I have not touched either:

1. Test Core (6/6) failed — a real test failure. ⛔ Never skip, disable or quarantine a test to get green; fix the cause.
2. Fixes #18050 is absent from the PR body. Without it the card will not close and Closing-Target Claim Guard refuses. Add it.

⛔ Nothing here is a review of the delivery — that comes after your report.

PM: my Fixes #18050 demand was WRONG — withdrawn. And here is the exact byte that fails Check Changeset.

1. ⛔ Withdrawn: the closing keyword. You were right, I was not.

I told you twice — in a PR comment and in your dispatch brief — to add Fixes #18050. That was my error. Your body says it plainly:

the dispatch asked for a closing keyword; the body deliberately does not carry one, because fork 2 is answered but not implemented.

Card #18050 carries two decision forks. You implemented fork 1 and answered fork 2 without implementing it. Fixes would have closed a card with half its work outstanding — exactly what Part of exists to prevent, and the repo's own convention is that a Part of card goes back to pm:queue rather than being closed. Part of #18050 is correct. Keep it. ⛔ Do not add a closing keyword.

⭐ You pushed back by documenting the reasoning in the body rather than complying with a wrong instruction. That is the right behaviour and it is the second time this seat has been corrected that way tonight. The PM will close or re-queue the card by hand, as your body asks.

2. ⚠️ Still owed, and it is one character: the Clause-② line is backticked wrong.

Check Changeset has now refused twice with "a near miss, not a declaration". It is not your line's position — it is at the start of line 2, which is fine. It is the backtick span.

Your line:

`Clause-②: no` — re-derived from the delivered diff, with the control, below.

The gate's predicate is:

/^[ \t]*(?:>[ \t]*)?(?:[-*][ \t]+)?(?:\*\*)?(`?)Clause-②(`?)(?:\*\*)?[ \t]*:(.*)$/

It tolerates a backtick around the key only. Yours opens before Clause-② and closes after no, so the colon and the value sit inside the span and the value reads back as no` — with a trailing backtick — which is not the token no.

Either of these is read correctly:

Clause-②: no

`Clause-②`: no

⛔ The gate says this clears "with no push and no re-run" — it re-reads the body on the next edited event. So this needs a body edit, ⛔ not a commit.

3. Unchanged and ⛔ not to be redone

The carrier is cleared on both carriers; Clause-②-correction: 5656739436 on card #18050 declares Clause-②: no; check-clause2-carriers --pair 18081 exits 0. I re-derived on your new head a3950e4fa: 0 added export lines, and the added ok: / error: keys already exist on main in that file, so DeliveryOutcome is reused and no payload is widened. The declaration stands.

Those three lines describe exactly the defect #18050 fixes, so removing the row falsified them. turbo then stopped on the failing task, which is why plugin-auth and downstream-contract read "never reached" — a consequence, ⛔ not the cause.

⇒ the test was pinning the defect. Verified against the diff, ⛔ not taken from the report.

The repair makes the pin STRONGER, which is the part that matters

before	after
expect(rows).toHaveLength(1) + status: 'dead' + error-text match	await dispatcher.tick() kept, then expect(rows).toHaveLength(0)

⭐ Retaining the tick() is the load-bearing choice: without it toHaveLength(0) would pass trivially before the dispatcher ran. With it, the assertion reads "no row exists and none appears later" — strictly stronger than "a dead row exists".

The unmeasured: 1 → 0 move is justified from notify-node.ts's own contract, not waved through: unmeasured means the dispatcher decides later, and after this change there is no later, so the count is known and zero. #7747's invariant — the summary must not out-count what the durable record shows delivered — is asserted unchanged, against a bound that went from 0 non-dead rows to 0 rows at all.

⛔ Nothing weakened, measured on the diff: 0 additions of .skip, .only, .todo, xit(, xdescribe(, @ts-ignore or eslint-disable. The file's historical narrative was amended honestly ("At the time #7747 landed…") rather than deleted.

Verification that earned its green

⭐ The dev ran the two packages the aborted shard never reached — plugin-auth (110 files / 2340) and downstream-contract (3 / 31) — on the stated grounds that a shard which stops early cannot be read as "the rest passed". That is this card's own false-green subject applied to its own verification, and it is why the green is trustworthy.

Ablation: predicted RED, observed RED, failing on the new assertion (toHaveLength(0)) ⇒ the updated pin discriminates rather than passing vacuously. Restore proven by state (on-disk blob == HEAD blob, git diff HEAD empty), ⛔ not by an exit code. All readings taken on a built closure, because service-automation resolves service-messaging through dist/.

Landing state

• 11 distinct workflows (= the open-PR reference), newest run of each is green, 0 non-green. ⚠️ Judged per-workflow: an earlier PR Automation run failed and was superseded by the 00:49:06Z run after the body edit — a naive "any run red" read would have miscalled this.
• check-clause2-carriers --pair 18081 → exit 0, reading the Clause-②-correction that supersedes the claim's yes with no.
• check-governed-merges --pr 18081 → 0 of 5 ⇒ NOT governed.
• Gates: 62 derived / 13 run / 0 NOT MEASURED / 49 UNRUN, the UNRUN named as the Lint & Repo Gates farm CI owns. ⛔ UNRUN, not passed.
• ⛔ Ledger untouched (0 hits) ⇒ this PR does not join the serial relay held by feat(plugin-auth): the bulk import admits manager_id, resolved in a second pass through the admin write surface's own refusals #18046.

⚠️ This is a Part of, not a Fixes — deliberately

Card #18050 has two decision forks; this lands fork 1 and answers fork 2 without implementing it. On merge the card returns to pm:queue for fork 2 — ⛔ it is not closed. I twice demanded a closing keyword here and was wrong; the dev declined and documented why, which is the correct behaviour and is recorded as this seat's correction 177.
