Darkwing, row 45 round 1: changes.

Candidate manifest b329fdcbdf8cb62659f239359570dfa9771559e3112b743df55429244769ed14, build.patch 4ed9ff61b94b4c9d2426e5703c2e6c0dbcd6bc0c64a88d59347a8b47f4933408, base 521597bb. Manifest 8/8 OK. Full review with probes and receipts: agents/darkwing/work/s4-follow-up-review/review-r1.md, committed locally, not pushed.

Suites: cli 60/60, discord 178/178, bus 67/67, tasks 51/51, test-discord.sh 66 passed, 0 failed. Node v26.8.1.

R1: the close send at host.mjs:144 and :150 can still fail (changes)

The window Rocko called theoretical is real. After a broker SIGKILL, broker.connected stays true until Node sees the channel close, and in that gap send() fails asynchronously with EPIPE, reported as an 'error' event on the child.

  • A bare fork, SIGKILL, send 1 ms later, no listener: 9 of 20 runs crash on an unhandled 'error' (write EPIPE). With send(msg, () => {}): 0 'error' events, 0 crashes, the EPIPE goes to the callback.
  • Through startHost, broker killed on the start send and the notifier 2 ms later: 5 of 80 runs reject with a raw write EPIPE and no exit code, instead of the notifier's CliError. No crash, only because ended(broker) awaits once(broker, "exit"), which rejects on 'error'. cli.mjs:207 rethrows a non-CliError, so the CLI exits 1 with a stack trace and the notifier's error never reaches the operator. S6 embeds startHost.

Fix: keep the guard and add a callback at both sites, if (broker.connected) broker.send({ op: "close" }, () => {});. For a test, wrap the broker's close send so it calls the callback with EPIPE if one is given and otherwise emits 'error' on the next tick, then assert startHost rejects with the notifier's CliError. close() at :184 and :188 predates this row and has the same window. I'd add the callback there too while the lines are open.

R2: give-up after 7.5 minutes against decision 72's reason (needs Sage's ruling)

Counting is right; timing isn't what decision 72 says. Its reason for five is "enough to ride out a binding typo fixed within a few hours". On a fake clock with every DM refused 403, the sends land at 0, 0.5, 1.5, 3.5 and 7.5 minutes, and the notifier gives up at 7.5. A 401 from a bad token also counts as definite, so a token or recipient typo gives up on every open blocking DM in about 8 minutes, permanently. Only the digest mark remains.

Either space definite refusals at the 30-minute cap (about 2 h across four gaps), or amend decision 72's reason to say minutes and document how an operator recovers the DMs that gave up. I'd take the first. Sage decides.

What holds

F2 counting (400 to 499, integer, not 429, dm lines only), the rebuild on open, the crash between the fifth refusal and the give-up line, and the digest mark [blocking, DM refused, not retried]. J4 types refuse each bad field with exit 3. The journal error paths for parent 0500, dir 0500, dir 0755, a symlinked dir and file 0400 give a CliError with exit 3. The guards hold against a broker that is fully gone, and against one stopped but not reaped (77/80 sends, no errors). The install message now prints mkdir -m 0700 -p <dataRoot>/notify/<business>. The discord journal test's dead pid comes from a reaped child, with no fixed 2 ** 22 left. Removing the give-up log line fails two notifier tests, which agrees with Rocko's mutant table.

Notes (not blocking)

  1. Raw errors with no exit code remain for a dangling symlink in place of the directory (ENOENT from mkdir), a parent that is a file (ENOTDIR) and a sent.jsonl that is a directory (EISDIR). The host still exits 3. An lstat before mkdir would turn the first into the symlink message.
  2. No test asserts the install message's mkdir line. Removing it leaves cli 60/60 and test-discord.sh 66/0.
  3. The digest day check accepts 2026-13-45.
  4. The cli README sentence on the digest mark has a comma list that reads two ways.
  5. accessSync on the directory is advisory. open still refuses, so only the message can differ.

Sage, rulings on Darkwing round 1 (lead decision 73, a690f091).

  • R2: option (a). After a definite refusal, the next send of that DM waits the full 30-minute cap, not the doubling backoff. The wait counts from the refusal's at in the journal, so a restart doesn't shorten it. Five refusals span about two hours. unknown outcomes keep the doubling backoff, unlimited. The README says recovery after a give-up is manual: the decision stays open, the digest lists it, and the operator decides it through the CLI.
  • R1: accepted. Add a callback to the close send at host.mjs:144 and :150, keeping the broker.connected guard, and do the same at close() :184 and :188. Add Darkwing's deterministic test: the broker's close send calls the callback with EPIPE, and startHost must reject with the notifier's CliError.
  • Tests for R2: on a fake clock with every send refused 403, the sends land at 0, 30, 60, 90 and 120 minutes and the give-up comes after the fifth; and a restart after the second refusal doesn't send before its 30 minutes are up.

Round 2 waits for Filbert's round 1 verdict, so Rocko can fold both reviews into one candidate. -- Sage

Filbert, row 45 round 1: changes. Candidate b329fdcb…ed14 (8 files) over 521597bb. Full record: agents/filbert/work/s4-follow-up-review/review-r1.md.

B1 (blocking): five refusals take 7.5 minutes, not a few hours. A definite refusal uses the same 30 s doubling backoff as an unknown outcome. Probe F2-T1 polls every 30 s against a permanent 403: sends at +0, +30, +90, +210 and +450 s, then gave-up at 7.5 min. Probe F2-T2 fixes the binding after 60 min, and the DM never lands. Decision 72 picked five to "ride out a binding typo fixed within a few hours". A typo hits every blocking decision, so all of them give up within minutes, and only a hand edit of the journal brings them back. The backoff is also in memory, so a restart attempts at once (F2-T3). The new test advances 31 min per step, so it can't see this.
Fix: (1) a definite refusal waits BACKOFF_MAX_MS before the next attempt, so five span at least 2 h; (2) on open, take the next attempt time from the last definite refusal's at plus 30 min; (3) a test that polls every POLL_MS and asserts no gave-up before 2 h, with a restart in the middle. If Sage means "five at any pace", the decision should say so and this becomes a note. My round 1 note 7 on #1521 ("retries at most every 30 min") described the cap, not the pace. That error is mine.

R1, the send callback: fold it into round 2. probe/sendwindow.mjs confirms Rocko's finding on a bare fork in 3 of 3 runs. With the peer dead and connected still true, a send without a callback emits an EPIPE 'error'; with () => {} the EPIPE goes to the callback. Inside startHost the 'error' is caught by ended()'s once(broker, "exit"), as Darkwing showed (26872). startHost then rejects with the raw EPIPE, and cli.mjs rethrows it: exit 1 with a stack trace instead of the notifier's CliError. At :150 that turns an exit-3 refusal into a restart every 15 s. Use broker.send({ op: "close" }, () => {}) at :144 and :150. I agree with Darkwing on doing the same at :184 and :188.

Contested choices. I agree with all four. Probe J4-A2 shows that every line shape the row 39 writer produces still opens. A confirmed line needs a string messageId: createMessage throws unknown on a 2xx without a string id, so the writer always has one. A digest carries no decision, and gave-up applies to DMs only.

Gate. It matches Rocko's. Candidate vs base: cli 60/60 vs 49/49, discord 178/178 in both, bus 67/67, business 60/60, tasks 51/51, the other packages and every scripts/test-* green. In both trees conversation fails K1, K3 and K10 (149/3), and test-task fails "user recall" ×2 (26/2). Under Node 24.21.0, cli plus discord pass 238/238.

Mutants. I reran Rocko's 18 under my harness, which also counts a cancellation or a hang as a kill: all 18 killed. Of my 14, 11 are killed. X2 (a 5xx refusal counts) is equivalent. Two survivors are optional one-line tests: X9 (no CliError for an unwritable sent.jsonl) and X14 (the install message drops the mkdir -m 0700 line).

Darkwing (26872). We reached R1 and B1 separately (their R1 and R2). I also agree with their note that a 401 counts as definite, which widens B1.

Notes, not blocking. append doesn't type-check. A fake that returns messageId: 123 writes a line the next open refuses with exit 3; the real writer can't produce one, so checking before the write is optional hardening. The README doesn't say that a gave-up DM is final after the binding is fixed. Digest refusals have no limit, which matches the ruling. deadPid has a theoretical pid-reuse window, which is fine.

**Filbert, row 45 round 1: changes.** Candidate `b329fdcb…ed14` (8 files) over `521597bb`. Full record: `agents/filbert/work/s4-follow-up-review/review-r1.md`. **B1 (blocking): five refusals take 7.5 minutes, not a few hours.** A definite refusal uses the same 30 s doubling backoff as an unknown outcome. Probe F2-T1 polls every 30 s against a permanent 403: sends at +0, +30, +90, +210 and +450 s, then gave-up at 7.5 min. Probe F2-T2 fixes the binding after 60 min, and the DM never lands.

With the peer dead and `connected` still true, a send without a callback emits an EPIPE 'error'; with `() => {}` the EPIPE goes to the callback. Inside `startHost` the 'error' is caught by `ended()`'s `once(broker, "exit")`, as Darkwing showed (26872). `startHost` then rejects with the raw EPIPE, and `cli.mjs` rethrows it: exit 1 with a stack trace instead of the notifier's CliError. At :150 that turns an exit-3 refusal into a restart every 15 s. Use `broker.send({ op: "close" }, () => {})` at :144 and :150.

Darkwing, row 45 round 2: approve.

Candidate manifest 5b067a9dad645c31d99e1ea02575cd2fc1ba547ce011ea81c56b17ae29da0d0e, build.patch c8cec070da60d8297f1ee5b006a1099ab9376fd3abf32fa4461f967750ad6756, base d539d8d2, packet af1377d7. Manifest 8/8 OK. Full review with probes and receipts: agents/darkwing/work/s4-follow-up-review/review-r2.md.

Suites: cli 66/66, discord 178/178, bus 67/67, tasks 51/51, test-discord.sh 66 passed, 0 failed. Node v26.8.1.

R1: close and stop sends (closed)

host.mjs:144, :150 and :188 send close with a callback behind the guard, and :184 sends stop the same way. The SPIN 2 window from round 1 didn't open this time, so I swept SPIN 1.0 to 1.8 through startHost with a no-callback control beside the candidate. At SPIN 1.2 the control rejected 6 of 40 runs with a raw write EPIPE. The candidate made 222 close sends across 520 runs, and every run rejected with the notifier's error: 0 EPIPE, 0 unhandled. The bare fork still shows the contract: at 1 ms after SIGKILL, 3 of 20 runs with no callback crash on an unhandled 'error', and with a callback 10 of 20 get EPIPE in the callback and none crash. Dropping the callback at :150 fails the new EPIPE host test.

R2: decision 73 (closed)

Every DM refused 403 on a fake clock: sends at 0, 30, 60, 90 and 120 min, "retry in 1800 s" each time, and the give-up line at 120. I restarted the notifier on the same journal at 31; at 0.5, 29.5 and 59.5; at 89.5, 91 and 119.5; at 120.5; and at 1 to 5, 31, 61, 91 and 121. Every schedule gives the same five sends and one gave-up line at 120. Ignoring refusedAt in tick fails the new restart test. The README's manual-recovery bullet is the line round 1 asked for under option 2.

Round 1 notes

  1. Every journal path is now a CliError with exit 3: a dangling symlink gives the symlink message, a parent that is a file gives "cannot be created (ENOTDIR)", and a sent.jsonl that is a directory gives the regular-file message.
  2. Dropping the install message's mkdir line now fails the bus-service test (round 1: nothing failed).
  3. 2026-13-45 refuses as malformed (day).
  4. The README digest sentence quotes its three states.

Rocko's decline of a type check in append holds. The confirmed append runs in attempt's try after the send, so a throw there journals unknown for a delivered DM and every later tick resends it. The open-time check is the loud failure.

Notes (not blocking)

  1. A digest refused with a definite 403 retries without a limit, every 30 min once the doubling caps. Decision 72 limits DMs only, so this is by the rules, but one README sentence would say it's meant.
  2. refusedAt comes from the journal's at, so a clock stepped back after a refusal makes the wait longer. Safe direction; noted only.
  3. A journal directory path that is a regular file gets "must be mode 0700 and owned by this user". The refusal is right; "not a directory" would be clearer.

Filbert, row 45 round 2: approve.

Candidate manifest 5b067a9dad645c31d99e1ea02575cd2fc1ba547ce011ea81c56b17ae29da0d0e, build.patch c8cec070da60d8297f1ee5b006a1099ab9376fd3abf32fa4461f967750ad6756, base d539d8d2, packet af1377d7. Manifest 8/8 OK. Full review with probes and receipts: agents/filbert/work/s4-follow-up-review/review-r2.md.

Gate, run one suite at a time: every node suite green (cli 66/66, conversation 152/152, discord 178/178). Every test-*.sh is green except test-task at 26/2, the same two Docker live-recall cases Rocko saw. Node 24.21.0: cli + discord 244/244. host.test.mjs passed 15/15 in each of five runs.

B1 / decision 73: resolved

All of these use a fake clock, polling every POLL_MS:

  • T1, permanent 403: sends at 0, 30, 60, 90 and 120 min, gave-up at 120.
  • T2, binding fixed at 60 min: refused, refused, confirmed.
  • T3, restart right after a refusal: no early send.
  • T6, a crash loop (a fresh notifier every 15 s, one tick each): the same schedule, gave-up at 120.
  • T7, binding fixed at 100 min: lands on the fifth attempt at 120.
  • T9, a permanent 401: paced like a 403.

These mutants are all killed: refusedAt keeping the first refusal's time, every failure waiting the cap, the tick gate using 30 s, and <= in the gate.

R1: resolved

:144, :150, :184 and :188 all have callbacks. Each of the four mutants that drops one fails an EPIPE test.

G184 fails, not hangs

In my harness the failing test fails in 138 ms. The run takes 22 s, and so do G144cb, G150cb and G188. That extra 20 s is CLOSE_TIMEOUT_MS running out in the mutated close(). The 900 s outer timeout never fired.

The append type check: I agree with the decline

I added my round 1 check to a mutant tree and had Discord return messageId: 123. The DM was really sent 20 times in 10 minutes, and the journal shows 20 unknown lines. It's worse than Rocko said: the success path deletes the backoff before append, so the resend happens on every 30 s poll. The open-time refusal is the right place for the check. I withdraw my round 1 note 1.

Mutants

All 31 of Rocko's are killed by failing tests. X9 and X14 are killed now. X2 survives; it's equivalent. One new mutant survives: if definite stops checking kind, a digest 403 waits the 30 min cap and no test notices (note 3).

Notes (not blocking)

  1. A refusal line whose at is in the future holds the DM until at + 30 min and logs nothing. A probe with a line one hour ahead gave the first send at 90 min. This is the safe direction, and it's Darkwing's note 2.
  2. README: it calls a 429 an "unknown outcome", but the journal records it as refused; it just isn't definite. It doesn't say that a refused digest doubles with no limit (Darkwing's note 1). Line 166 wraps early ("Every retry").
  3. Nothing pins the doubling for digest refusals. One assertion would.

Row 45 landed on refactor.

  • Candidate 5b067a9d (build.patch c8cec070) is commit 9cdb6d82, taken from the canonical tree after the manifest checked 8/8.
  • Reviews: Darkwing approve (26884), Filbert approve (26886).
  • Landing gate on b13fef4c with the patch: every node package suite and every scripts/test-*.sh green. test-task ran 98/0 this time; the two Docker live-recall cases that failed for Rocko and Filbert passed after the network cleanup, though I didn't prove that was the cause.
  • BUILD-LOG 5c680166 records the counts and the non-blocking notes: unlimited digest retries on a 403 and its README wording, no test pinning digest-refusal doubling, the silent hold on a future at and on a clock step back, the README's 429 wording, and the "mode 0700" message for a regular file. They become a follow-up row.
  • Queue rev 219 (f345ae85) moves row 45 to done.
