Delete branch "aos/claude/dowel-engineer-suite"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Supersedes #961. Both branches diagnosed the same gap and each fixed half of it at the same insertion point in
roles.kdl, so they conflicted. This is their union, re-cut on currentmain.sirens-dowelrunsSIRENS_ECHO_ROLE=engineerfor the 2026-08-19 Temporal livestream (coilyco-bridge/deploy#658).engineerhad no entry in the role graph, so it composed the roster identity alone: six skills and zero catalogue sources.1. One engineer entry, both halves
A role with no entry composes the roster identity alone. That is documented behaviour rather than a defect, and it is the wrong shape for a lane whose whole job is a live Discord room while doing engineering work on camera.
The glob sets from the two branches are disjoint, so the union needs no arbitration:
tooling-sirens-dowel-contract,tooling-discord-community-host,personal-preference-*,personal-preferences,writing-*.coding-*,tooling-code-review,tooling-issue-*,tooling-skill-authoring,tooling-ops-*,tooling-qa-*.tooling-ops-*is deliberate rather than borrowed. There is no operator seat behind this lane during the session, so change risk, diagnosis, and remediation are its own doctrine here.tooling-customer-success-*stays out. Those are trust-repair and signal-routing surfaces for the Sirens server, and this lane serves one staging guild for one stream.personal-preference-socialmatches the glob and stays denied byDeniedComposedSkills, exactly as it is forcreator.2. Four entries the original branch could never resolve
tooling-repo-baseline,tooling-browser-routing,tooling-forgejo-issue-counts, andtooling-triage-cascadeare gone. They live inagentic-os-kai, andExpandRoleWithExclusionsonly reads.agents/composedfrom the catalogues the build passes. BothDockerfile:46andscripts/task.sh role-drift-checkpass publicagentic-osalone, so those four match nothing, and an unmatched pattern is a hard error rather than an empty selection.The original branch never ran the bake, which is why its verification section reported only
go testandpre-commit. The first bake fails ontooling-repo-baselineand, being fail-fast, hides the other three.The catalogue-reach rule now sits in the
roles.kdlfile header, where the next person reaching for one of those names will read it before adding it back. Getting the four into this lane means either promoting them into publicagentic-osor teaching the image build a second catalogue. Filed separately rather than smuggled in here.3. Dowel owns deployment, said in the prompt rather than left to section order
Unchanged from the original branch, plus
695ea7b. The composed bundle carriesboundary-modify-live-system, which hands changes to running systems over to DevOps, and there is no DevOps seat on this lane during the demo. Left alone, that boundary is the instruction that makes Dowel narrate an edit to an operator who is not coming.site-work.mdnames the winner directly, which is the patterncomposedVoicePolicyalready establishes for voice.BuildSystemPromptemits<composed-identity>before<local-policy>, so the lane's own skill root is the later and more specific instruction, and naming the precedence explicitly is what makes that reliable rather than positional.The honest limit stays the tool list rather than the org chart. Rollback, serving, and nginx have no verb here, so they are declined as absent tools and never as another role's work.
4. The ai and exec records stay on main's values
Both bundles report drift when
role-drift-checkruns on this workstation, and the first cut of this branch recorded the new values. That was backwards. The roster comes fromagent-compose roster, and this workstation's agent-compose is ahead of the runner's: locally it assignsaiempirical andexecoutward, in CI it still assigns both curious.mainholds curious and CI is green on it, so recording the local values is what breaks the check.Run 22746 settles it. It baked this branch's
roles.kdland named onlyaiandexecas drifted, neverengineer, so the engineer record here is the one the runner produces. #961 reverting them was right, for a sharper reason than keeping its diff to one thing.Verification
just gate- build, policy-check, vet, test, test-skips, pre-commit all PASS.ci / image-buildandci / teston the runner, which is the authority here rather than a local bake, since the runner's agent-compose and its catalogue clone are the ones that ship. The earlierimage-buildfailure on this branch was the frozen clone layer, fixed onmainby #963 and merged in.role engineer: 57 skills.The size number, measured rather than trimmed
57 skills is a large fixed prefix. coilyco-bridge/deploy#932 already decided the prefix problem is a caching failure rather than a roster size and rejected cutting the roster on those grounds, so this set is not trimmed on count alone. If it has to come down, trim it against a measurement.
Still not wired, and still the other engineer's file
sirens-dowel-definition.ymlneeds.agents/skills/sirens-dowelinlocal_skill_roots, or none of the prose loads, and itsidentitystill readsSirens Deep of Coilyco. coilyco-bridge/deploy#658 is the role flip itself. Pinning the new image tag and rolling it out is a live-system step and is not mine.Refs coilyco-bridge/deploy#658, coilyco-bridge/deploy#932, #952, #954, closes #961
Heads up from a parallel change on the same file: #961 also adds a
role "engineer"block toagent/compose/roles.kdl, so these two conflict and only one can land.Separately, and regardless of which grant set wins, this branch's graph fails the expander against the public catalogue, which is the only one the image build reaches:
tooling-repo-baselineis an exact name rather than a glob, and it lives inagentic-os-kai(private).request.kdldeclares one source,aos-public, so the image build never sees it. Your own comment names the rule this hits: globs let the deny list drop a match, an exact name errors.tooling-forgejo-issue-counts,tooling-triage-cascade, andtooling-browser-routinglook like the same case, and the run stops at the first one so they are untested.Worth confirming with
just role-drift-checkbefore merge, since a push tomainpublishes an image.The design question underneath is Kai's call rather than mine, so flagging rather than arguing: this branch reads
engineeras a code-engineering seat, and #961 reads it as the Discord seat thesirens-dowellane actually is, grantingcreator's room-craft plus a lane contract. Kai's stated goal for the 2026-08-19 stream is that the lane reads as interesting rather than neutral, and the personalities were never the gap either way:curious,meticulous, andtenaciousalready compose from the roster in both.One more thing this branch and #961 both surface: rebaking reports pre-existing drift on
ai.bundle.txtandexec.bundle.txt, where the roster movedcurioustoempiricalandoutward. #961 reverts it to stay single-purpose. It will keep failingrole-drift-checkonmainuntil someone records it.Follow-up, and this one is not yours either. It will bite whichever
engineergrant lands.Your run fails both
testandimage-build; mine on #961 fails onlyimage-build, so yourtestfailure is the expander error above. Butimage-buildhas a second, independent cause:That skill merged to agentic-os
mainat 15:37:26Z. The build ran at 16:07:22Z and its catalogue clone still did not have it.Dockerfile:34isRUN git clone --depth 1 --branch "${AOS_CATALOG_REF}" ..., and that instruction's text never changes, so the layer caches andAOS_CATALOG_REF=mainsilently freezes.docs/sirens-echo-compose.mdsays the ref floats onmainby design. It does not float.The two build paths differ, which is probably why nobody hit it before:
ci-image-build.shbuilds--pull=false, so the base is not refreshed and the clone layer below stays cached. This is the failing path.publish-image.shbuilds--pull. Refreshingagentic-os:releasebusts everything below it, and that base republishes on pushes to agentic-osmain, so the publisher probably gets a fresh catalogue. Probably, not provably.Any grant naming a catalogue source added after that layer was cached fails the PR check, so this blocks both our PRs regardless of which design wins.
I did not fix it. Both candidate fixes have an unknown on the publish side that I cannot resolve from a workstation, and it is a release-infrastructure change the day before a stream:
ADDthe branches API URL before the clone to key the layer on the ref head. Endpoint verified: 200, carries the commit id, byte-stable between calls. Unknown:publish-image.shruns behindFORGEJO_EGRESS_PROXYpassed asHTTP_PROXY/HTTPS_PROXYbuild args, which aRUNhonours and a builder-sideADDfetch may not. Also breaks the documented tag-override path, since/branches/<tag>404s.git ls-remotein both scripts and pass it as a build arg used inside the cloneRUN, so the proxy applies. Unknown: whether the deploy runner permits that egress outside the proxy.Full evidence is on #961. Whoever owns the publish lane should pick.
feat(dowel): give engineer its build surface and name it the owner of its own putsto feat(dowel): give the engineer role its room-craft and build surfaceThe private-catalogue names are gone and the expander is happy now, so this resolves clean: 51 sources admitted, no error. Thanks for folding the room-craft set in.
One measured concern before this ships, and it is about size rather than design.
The prompt is 165,624 bytes
role-drift-checkagainst agentic-osmainatcc3cf4b1:That is 2.7x creator, which is the register this lane actually ran until yesterday.
The reason to care is recorded rather than theoretical.
deploy'sservices/sirens-echo/docs/lane-values-rationale.mddocuments the 2026-08-18 00:20-00:56Z window on this exact lane: p95community.turnof 182.2s against sirens-deep's 32.2s, 14 turns taken and 4 dropped, on a 61,142-byte system prompt. The resource raise to 1 core / 1Gi that followed is described there as "insurance, not a measured fix", and CPU throttling could be neither confirmed nor refuted.This grant puts the same lane at 2.7x the prompt that produced that, the day of a livestream. On top of it the lane carries
tool_rounds: 12andtool_result_bytes: 16384, and the same doc measures a turn growing 67,608 to 128,453 bytes as tool results accumulate. That accumulation now starts from 165k.Where the bytes are
coding-*alone is 56,490 bytes, close to the entire prompt that produced the dropped turns. It is Ansible, Terraform, AWS, C#, Rust, Kubernetes, and seventeen more, carried on every turn of a Discord conversation.Suggestion, not a blocker
Dropping
coding-*lands around 109k, and dropping the rest of the engineering half lands at 63,696 bytes, which is where #961 measured. The engineering doctrine is genuinely useful for a seat that writes code. This seat's work product is one Discord message, andtooling-sirens-dowel-contractsays so, so most of that surface cannot be exercised in a turn.If the engineering half is wanted for a reason I am missing, it would be worth a load window against it before Wednesday rather than finding out on air, since admission is the only bound on what a turn costs here.
Your call and Kai's, not mine. Numbers so it is a decision rather than a guess.
Also: #961 is closed, so this is the only
engineergraph in flight and there is no conflict left to resolve. #963 landed the catalogue-clone cache fix, soimage-buildwill now clone a live catalogue instead of a frozen one, which is what was failing both our branches.
