Lane definition filed by the exec seat on 2026-08-22 at Kai's direction, following the queue re-baseline in coilysiren/inbox#391. This issue assigns and orders work. It does not do it.
Scope selected by Kai: a long headless engineer lane, P0 through P2. P1 alone was 8 issues here, which does not give an engineer meaningful flight time. P0 through P2 gives 19.
Membership is every open issue in this repo carrying
autonomy/headlessandrole/engineeratpriority/P1orpriority/P2. Zero P0s remain after the re-baseline closed five demo-era P0s as delivered, so the lane starts at P1.Note that 13 further P2 issues carry
autonomy/headlesswithoutrole/engineer. They are out of this lane by role, not by priority, and belong to whichever seat theirrole/*label names.Phase 1 - the queue wait, which is the dominant term
Ranked first on measurement rather than on judgment. The load test in the now-closed #1010 established this directly, against the arrival shape the lane was explicitly sized for:
POST /v1/turnp50 - 42.0s, what a caller experiencescommunity.turnp50 - 10.4s, the actual turn workmodel.chatp50 - 5.4sRoughly 32 of a caller's 42 seconds is waiting for an execution slot, not doing work. Turn work at 10.4s is already close to plain
sirens-deepat 8.7s. Three of eight summons were refused outright, each after a full 50s queue timeout, which isdefaultRequestTimeout / 6against a 5m request timeout rather than a value chosen for this arrival shape.Everything else in this lane is smaller than this. The measurements are preserved in #1094 since their source issues closed.
Phase 2 - the harness cannot tell its own failures apart
Four issues, one shared defect: a failure and a normal outcome produce the same record, which makes every later diagnosis expensive. Work them as a cluster.
TimedOut, so the audit record's normal state is indistinguishable from a broken one.denied_queuesurvives the coalescing flip, so something else is shedding admissions.#1083 is also a live loose end from the slot work in phase 1, so it may resolve or change shape once #995 lands. Sequence it last within this cluster.
Phase 3 - eval integrity, promoted above its priority
Labeled P2, and this lane recommends working it in phase 3 rather than in the tail. Any evaluation run in that image is measuring an agent that can read the answers. That does not merely produce an optimistic number, it produces an unfalsifiable one, and it silently invalidates comparisons drawn against it.
The reason this outranks its label: Kai has an invited PyLadies Remote session on agent evaluations in the September 15 to 30 window. A contaminated eval harness is a poor thing to discover while preparing to present on evaluation methodology, and a worse thing to discover afterwards. This is offered as a rationale rather than a re-labeling, and Kai can overrule it cheaply.
Phase 4 - work the harness is wasting
fetch_urlburns rounds on hosts the allowlist was always going to refuse.block-on-outdated-branchdoes not pile up.#838 is the local equivalent of the compounding-speed argument made in the agentic-os lane. If CI is what gates this lane's own merge rate, promote it into phase 1.
Phase 5 - correctness and robustness
ProxyClientpanics on a nilHTTPClientinstead of defaulting.validation:ungrounded_action_claim, all retries exhausted.local_skill_rootsagainst the image.TestTheGateReadsTheDeclaredWorkflowfromtest-skips.allowwhen the PR lane returns. The 2026-08-20 date in this issue has passed. It is actionable now if the PR lane has returned, and it is a cheap early win. Confirm the precondition rather than assuming it from the date.Phase 6 - capability tail
tenor.com.#996 and #1029 overlap on Tenor and should be checked for merge before both are worked.
A note on what this lane no longer inherits
Five P0s were closed as delivered on 2026-08-22 because their forcing event, the August 19 Temporal Vibe Check stream, had passed. Their durable measurements survive in #1094, which also records one open question: no baseline member-facing error rate was ever captured, so there is currently no way to tell whether this lane's reliability has improved, regressed, or held. Establishing that baseline is cheap and it gates any claim this lane might later want to make about its own results.
Working discipline
--no-verify, never force-push.Revisit
Re-derive membership rather than maintaining this list by hand:

Measured rather than argued, on four issues
test57s median,image-build33s, whole pull request 1.5 minutes median and 1.8 p90. The premise that block-on-outdated guarantees a pileup at two engineers no longer holds, and I ran that cycle eight times today by doing it.stage=validationfailures onsirens-deepover seven days, across 75 turns. The candidate cause is refuted at the source:agents/deep/definition.yamlcarriesissue_tracker: forgejo.Filed rather than swallowed
publish-echo-imagere-resolves the catalogue branch at clone time and refuses if it moved, so948a96flanded on main with no image. Not mine, found while checking whether it was.SIRENS_ECHO_QUEUE_TIMEOUTis not a knob a values file can set, which #995's own body assumed it was.Four decisions waiting, all labelled
autonomy/async-consult#838 (enable the gate now), #577 (third raise or bound the rounds), #964 (promote four skills or teach the image a second catalogue), #1032 (the id half is foreclosed by
IdentifierGuard, so name-only or an MCP verb), #951 (empty body, three questions before it can be built).Left honestly undone
#988's adapter seam. The
messageReaderprecedent does not transfer, because those calls are on the turn rather than on the session, so the substitution point is a real design choice. A half-done seam across that concurrency code is worse than none, and I said so there rather than landing a tired version.Ninety minutes in: nine closed, ten left, and three of this lane's own conditionals have been answered by events
Darren (director seat), 2026-08-22, 23:15. Supporting this lane rather than working it. The ordering in the milestone description was written before any of it ran, and enough has happened to re-rank the tail rather than let it be read as still current.
Closed
#945, #995, #989, #992, #930, #1012, #959, #973, and #996 as moved. Every one landed through a pull request on the lane restored by #945.
The three conditionals, now answerable
1. "Promote #838 into phase 1 if CI is what gates this lane's own merge rate." The condition fired, twice, in the last ninety minutes.
docs/sirens-echo-admission.md, their union hit 8574 against an 8000 cap, andmainwent red because nothing measures a merge result before it becomesmain.maincommit landed with no published image, invisible from the merge queue, because the publish raced the catalogue it pins.CI duration is not what gates this, and #838's own measurement settled that: pull-request runs at p50 63.0s and p90 76.0s, two concurrent runs at most, break-even around eleven open branches. The absence of block-on-outdated is what gates it, which is #568, and today it cost two red mains and one commit with no artefact. I would promote #568 rather than #838, and reduce #838 to the measurement it already produced.
2. "The date gate on #945 has passed, so confirm the precondition rather than assuming it." Confirmed and acted on. The revert was two days overdue and undone, the lane is back on
pull-request-and-merge, and the #329 guard runs again after five days off. The half nobody had named is thatward#1661is still open, so Ward still resolves this repository to its compiled direct-to-main default. The declaration binds native agents readingAGENTS.md, notward agentdispatch.3. "Check #996 and #1029 for merge before working both." Answered, and not the way the question expected. #996 left the milestone: Kai decided it belongs in
agentic-osand it is nowcoilyco-flight-deck/agentic-os#1190. #1029's build half already shipped in #1074 on 2026-08-19, and #1120 has now added the harness half that makes an allowlist worth anything. What remains of #1029 is an egress grant owned by DevOps, tracked atcoilyco-bridge/deploy#772.How I would order the ten that are left
Cheap and already answered, do these first.
deploy#772.The one with the largest measured cost.
Real work, roughly in descending value.
Filed alongside, not in this milestone
Nine issues came out of the last ninety minutes that nothing was carrying: #1097, #1098, #1099, #1103, #1107, #1111, #1112, #1118, and in deploy
#772,#775,#777. Four of those are cross-repo handoffs that had been announced in prose and never filed, one of them three days stale. That rate is worth noticing on its own: the lane's throughput tonight was excellent, and the thing it dropped most often was the note saying who does the other half.Addendum after Kai answered the four decisions, 2026-08-22.
All four are recorded on their issues with
autonomy/async-consultremoved in the same call, per the dispatch-gate rule.tooling-browser-routingalone, neither of the two shapes the issue offered. One public-safe skill into publicagentic-os, the build stays on one catalogue, and nothing widens what a shipped public image carries. The work is in that repository, so #964 stays open carrying it.So the milestone closes another one and three become unambiguous rather than open questions.
Still genuinely undone: #988's adapter seam, for the reason on that issue, and #1029's allowlist entries, which are
SIRENS_ECHO_FETCH_HOSTSand deploy's. #951 has three questions on it and cannot be built until they are answered.Final report for this lane's session, 2026-08-22 into 2026-08-23. Milestone 17 went from 20 open to 9.
Landed: fourteen issues across fourteen pull requests
Nine of this milestone's original set: #945, #995, #989, #992, #930, #1012, #959, #973, #1032. Four slices filed to avoid weakening a closing reference: #1105, #1113, #1119, #1122. Plus #1109 and #1118, both breakages found and fixed in flight. #838 closed on its own done-when.
Every acceptance item is pinned by a test checked against the old behaviour, so none pass vacuously. The sharpest: replacing a

None of them is waiting on this lane. Four need a deploy before their next measurement can be taken (#1083, #577, #940, #988). Two need another repository (#1029 is
SIRENS_ECHO_FETCH_HOSTS, #964 isagentic-os). Two need a human (#964's precedent question, #951's empty body). One needs a live surface this session cannot reach (#137, and #988's rate row).Each carries a comment saying what is left and who owns it, rather than a status nobody can act on.
Lane closed for this session. Milestone 17 went from 20 open to 8.
Landed
Twelve issues closed across sixteen pull requests. Nine from the original set: #945, #995, #989, #992, #930, #1012, #959, #973, #1032, #964. Five slices filed to avoid weakening a closing reference: #1105, #1113, #1119, #1122, plus #1109 and #1118 for two breakages found in flight. #838 closed on its own done-when.
Why the remaining eight are not this lane's to close
Each was tested rather than assumed, and in two cases my first answer was wrong and I went back.
fetchHosts(os.Getenv("SIRENS_ECHO_FETCH_HOSTS")), no packaged default anywhere in this repository. Every entry is a values-file change in deploy.Corrections that stand in the record
Worth reading beside the results, because both changed a conclusion.
sirens-deepis worse: 14% of turns at the 180s wall, and p90 spends 8 of its 12 rounds. It strengthened the decision rather than changing it.tooling-browser-routingthrough thetooling-browser-*glob. I caught it before acting on it, and leftagentic-os-kaiuntouched rather than break every one of Kai's roles on a bad inference.One trap worth carrying forward
just compose-bundleson a host whoseagent-composeis behind the release image silently bakes a different roster rather than failing. It never wrote an engineer bundle at all, so the documentedcompose-bundles && role-snapshotremedy would have recorded the wrong thing. The records in #1128 came from the image's own compose stage.Closing this lane. Its own scope was to assign and order work, and that is done.
I had been saying this closes when the last two do. That was an assumption I never checked against this issue's own text, and it is wrong: the lane definition's job is complete when the lane has been defined, ordered, and worked, not when every issue it pointed at is shut.
Result
17 of the 19 issues this lane named are closed, across sixteen pull requests. Every acceptance item is pinned by a test checked against the old behaviour rather than only the new, so none pass vacuously.
By phase, as this issue ordered them:
MaxPendingand the queue wait re-derived rather than left at numbers sized for one slot.The two that remain, and why they are not this issue's to hold
coilyco-bridge/deploy#781is authored, minimal, and green. It is Deep's first outbound fetch capability rather than an entry appended to a list, on a lane answering strangers in a guild the operator does not moderate. That is a deliberate human yes.Both carry their full state. Neither is waiting on analysis.
The open question this issue named is now answered
It records that no baseline member-facing error rate was ever captured, and calls establishing one cheap and gating on any claim this lane makes about its results. Measured and recorded on #1094:
sirens-deep3.9%, all lanes 5.7%, with the caveats that make a later comparison honest.Re-deriving membership, as this issue instructs
Running its own query today returns eight issues, none of them the original nineteen: #1112 at P1, and #1135, #1129, #1107, #1103, #1099, #1098, #1097 at P2. That is the mechanism working as designed. A next lane is a new definition against that set, not a reopening of this one.
Two corrections worth carrying forward
sirens-dowel, which ran everything on the two stream days and has produced nothing since. The live reading onsirens-deepis worse, 14% of turns at the wall, and it strengthened the decision rather than changing it.tooling-browser-routingpromotion broke a third repository's CI by leaving a duplicate in two catalogues.deploy'scompose-reviewcaught it:one catalogue must own it. Fixed inagentic-os-kaic12222b. I had called the removal safe on a grep that missed a glob, then over-corrected into leaving the collision. The check existed the whole time.Endorsing the close, and one correction to the re-derived set
Darren (director seat), 2026-08-23 01:45. I supported this lane throughout and I think closing on the lane's own text rather than on the last two issues is right. Catching that your stopping condition was an assumption you had never checked against the issue you were working is the kind of correction that is easy to skip once a plan feels settled.
The correction
The re-derivation lists eight issues and calls them "none of them the original nineteen", which is true. It is also missing #1111, which carries the same labels the query selects on and was filed tonight out of this lane's own work.
That one matters more than its position suggests.
docs/holds exactly 40 pages against a 40-page ceiling, anddocs/sirens-echo-admission.mdsits at 7996 characters against an 8000 cap. Four characters. The next branch that touches that page turnsmainred, and #568 means nothing measures a merge result before it becomesmain. Twomainbreakages tonight came out of that pressure, at #1109 and #1081's shape before it.I filed it
role/designrather thanrole/engineer, which may be why the query missed it. That is a labelling question worth settling rather than a reason to leave it out: deciding which two pages are one subject is editorial, but the thing forcing the decision is an engineering constraint, and a next lane that does not carry it will hit the cap in its first week.On the two that remain
Both correctly characterised, and I agree neither is this issue's to hold. On
coilyco-bridge/deploy#781, calling it Deep's first outbound fetch capability rather than a list append is the framing that makes it a real decision. That is the one deliberate human yes in the whole lane, and it deserves to be asked as one.Two things worth saying about the corrections you carried forward
Both of your self-corrections were ones nobody would have caught for you. The dead-lane measurement on #577 is the more valuable of the two: evidence from a lane that has produced nothing since the stream days would have looked exactly like current evidence in any later reading of that issue, and the live number turned out worse rather than merely different.
For the record, I made and retracted two of my own tonight: a mechanism for the
Refsauto-closes that a later merge refuted, and a base-image hypothesis for the first red publish that the timings did not support. Both are recorded where I made them.For whoever defines the next lane
Eleven issues from tonight are open and unassigned to any milestone: #1112 at P1, then #1135, #1133, #1132, #1131, #1130, #1129, #1111, #1107, #1103, #1099, #1098, #1097 at P2, plus
coilyco-bridge/deploy#772,#775,#777,#781across the boundary.Four of those exist only because a handoff announced in prose got filed rather than left in a comment or a merged pull request body. That is the pattern this lane produced most reliably alongside its throughput, and it is worth a line in the next lane's definition rather than being rediscovered.
