QA

Findings from running Gaia’s hosted pump on its own repository, observed at main 8ed4dfc.

Expected	What happens	Where	Measure	Status
A labelled issue can become a Draft	Intake needs exactly one branch carrying the issue’s evidence trailers, and nothing produced it; zero branches refuse like two, as HeadIdentityAmbiguous	src/hosted-draft-collector.mjs:319	2 of 79 branches carried the trailers, both hand-made; scheduled intake returned EXPECTED_NONE for days	Fix proposed in gaia#155, then observed working live 2026-09-25
An ambiguous Draft operation is reconciled	Issue 127’s operation stays EFFECT_AMBIGUOUS and is skipped on every scheduled run; it does not block the queue, but nothing settles it	src/hosted-draft-pump.mjs:310	Present in every intake receipt from 2026-09-15 to 2026-09-24	Reported as gaia#161
A seeder that wrote a branch says so	A connection abort during the read-back made it exit fail-closed while the branch had landed	src/evidence-head-seeder.mjs:147 (after the fix)	1 occurrence, on issue 106	Fixed in gaia#155 (49d5fb3)
An issue whose work shipped is closed	Issue 108 was open, although its gate was on main; the factory’s worker made no edit	tests/hexagonal-direction.test.mjs	0 edits, 1 factory run spent	Closed as completed, gaia#108
A factory job ends after its worker	Issue 108’s job was still STARTED about ten hours after its worker finished, holding the single host slot	C:/Gaia/state, portfolio:autonomous status	Worker done at 00:25 local, job STARTED at 10:00	Explained: watch stops on RECONCILIATION_REQUIRED (scripts/github-portfolio-autonomous.mjs:207); job retired with retire-closed 2026-09-26
A candidate marked CANDIDATE_READY and approved has passed its tests	No test is ever executed: the worker’s tools exclude a shell, the reviewer is read-only, and the “supervisor” that the prompt says runs tests does not exist in src/	src/factory-visible-claude.mjs:354	Issue 104’s approved candidate: 16/17 of its own tests, README gate count not updated	Reported as gaia#163; candidate fixed by hand 2026-09-26

2026-09-15 — Setup and versions

• Gaia at d68e900, the head of main on 2026-09-13. Checked out as a detached linked worktree so the tree was clean and nothing local leaked into an output.
• Node.js v24.12.0 on Windows 11. Gaia pins one exact release — .node-version and engines.node both read 26.8.1 — and nothing enforces it when you invoke node yourself, so everything in these lessons ran on 24.12.0 without a warning or a failure. Running it on the pinned release is to verify; the CI path is Windows with that release, and Ubuntu is described as portability discovery rather than a gate.
• Zero dependencies, so no npm install before any of this, and no node_modules in a clean checkout. The claim is not marketing: package.json has no dependencies and no devDependencies key at all, and the test runner is node --test.
• Every bus command ran against a throwaway data directory via GAIA_INTERAGENT_DATA_DIR, so nothing touched a real workspace. Outputs are pasted unedited except for shortening absolute paths to ….

2026-09-15 — What the commands actually reported

Command	Result
doctor, empty directory	ok: true, exit 0, supportedMaxLiveLanes: 4, and a note saying to run initialize --apply
initialize	dry run by default; --apply appended exactly one actor.registered
bus-cli tools	exactly 6: register, send, inbox, ack, heartbeat, handoff
verify	37 checks passed, 0 failed, in 8 sections, evidenceGatesResult: false
node --test	2075 tests, 2074 pass, 0 fail, 1 skipped, 38.9 s
factory:smoke	completed, evidence log fixed point sha256:256a51d2… over 15 events / 6,315 bytes, evidenceGatesResult: true
inventory-digest	323 files, 5,937,493 bytes, ordinal-path-bytes-sha256/1 dccabe8f…

The full three-actor exchange in lesson 2 came to 10 events and 3,617 bytes on disk. That number is worth keeping in mind next to lesson 5’s cost model: replay is O(events × actors), and a genuine multi-party coordination session is tiny.

2026-09-15 — Surprises

A refusal is an event. Addressing an ambiguous actor name returns ok: false, exits 1, and appends command.rejected to the log. I expected the refusal to be a return value and nothing more. It is the detail that makes the log answer “what did this session attempt?” rather than only “what did it achieve”, and once seen it is hard to accept a system that logs only successes.

verify used to print a red check and exit 0. The README records the fix: both doctor and verify previously exited 0 on a log whose handoff had transferred authority, while verify displayed its own red check saying otherwise. A reader keying on the exit code, or on ok, read that as a pass. A tool that reports a failure and returns success is the exact failure mode lesson 1 is about, found inside the verifier — which is a good argument for the negative controls that now always gate.

The evidence checks split into two regimes, and that is deliberate. Five of them — three actors, more than one actor kind, a correlated thread, an acknowledgement, a handoff — are legitimately false on a correct empty workspace, so they report without gating unless the caller claims the log is evidence. I had assumed a verifier either checks something or does not. The hinge being the caller’s claim rather than the tool’s opinion is a better design than either alternative.

resolveLaneLimit takes an options object. Called positionally it silently returns the default, which is how I first mis-measured it. resolveLaneLimit({ requested: 6 }) throws with the full evidence statement; resolveLaneLimit(6) returns { limit: 4 }. Worth noting given that the module’s whole argument is that silent clamping is the mistake — the refusal is real, but only on the documented call shape.

The residuals are published, not buried. The factory design document states that a host-user worker cannot be proven to have avoided network, secrets or writes elsewhere, and that a receipt claiming containment would need a separate OS boundary. Most projects would have written “runs agents in an isolated workspace”. This one names the gap and the capability that would close it.

main has grown well past what this course covers. The hosted Draft pump on GitHub Actions, the drain Petri net, the control room, hybrid search, the runner capability probe, managed PR delivery rounds, test observation intake — docs/ holds 50-odd design records at the pinned revision. The five lessons cover the bus, the log, the factory and the limits. That is a deliberate tracer-bullet slice, not a complete map.

2026-09-15 — Corrections made while writing

• I first quoted the repository’s AGENTS.md for the “privilege is prevented by absence” rule. That file does not exist at d68e900 — it was an untracked file in a local checkout of an older branch. The quote was replaced with the README.md statement and the operator module’s own header, both verified present at the pinned revision. Every other quotation was re-checked against the pinned tree for the same reason.
• The local working copy I started from sat on a branch from 2026-08-29 whose README.md differed from main’s, and which had no ARCHITECTURE.md or CONTEXT.md. Starting from a clean pinned worktree instead of the checkout that happened to be open is the habit that caught it.

2026-09-20 — Issue 76 continuity candidate

• Design Receipt v7.4 was reviewed independently before implementation. The candidate is deliberately bounded to one work identity, one successor slot and one generation-0-to-1 replacement.
• The isolated Gaia candidate ran 2,261 tests: 2,259 passed, 0 failed, 2 skipped; its focused continuity/bus regression ran 87/87. npm run verify reported 37 passed, 0 failed, and npm run architecture:verify passed.
• The isolated Demerzel consumer ran 787 Python tests with 1 skipped and 10/10 IXQL checks while validating vendored Gaia schema/fixtures read-only.
• Review/integration found and corrected four material weak shapes: persistence imported into the controller, decisions allowed before exact wake delivery, idempotency keys replaying changed inputs, and tests omitting the bus sidecar. A simplification pass also removed avoidable scans and allocations.
• These are candidate-worktree measurements, not proof of publication, merge or release. The final formal review receipt, exact final commit gates and normal PR checks were still pending when this entry was written.

2026-09-25 — The hosted pump, end to end as far as a Draft

• Why nothing came out. hosted-draft-intake.yml had run every 6 h, successfully, and returned EXPECTED_NONE for days. Two causes, both on the Gaia side: no open issue carried ready-for-agent, and the collector requires exactly one branch whose tip carries Gaia-Issue: N and Gaia-Ready-Receipt: <hash of the label event>. No code produced that branch. The only two that ever existed were made by hand, and zero branches refuse the same way as two (HeadIdentityAmbiguous, because the test is matching.length !== 1). The Augment Cosmos automations were a red herring: the pump never depended on them.
• The fix, gaia#155: npm run draft:seed-evidence -- --issue N --apply creates gaia/issue-N-ready-K, one commit that reuses the default branch’s tree, so no file changes. It derives the receipt with the collector’s own function, extracted rather than copied, never applies the label, and lets the read-back decide the result.
• Observed live on issue 108: label → seed CREATED → intake ADMIT → Draft gaia#156 → the local factory (portfolio:autonomous watch, enabled once with a budget of 20 runs) took it within a minute. The same chain produced gaia#158 for issue 104.
• Two refusals that were correct: issue 148 came back StaleRevision because the pump had already drafted it on 2026-09-13 (#149): one Draft per work item. The factory’s worker on 108 made no edit, because tests/hexagonal-direction.test.mjs was already on main: the issue had stayed open after its work shipped.
• One defect found by running it: a connection abort during the read-back after a successful write made the seeder exit fail-closed, which implied nothing was written, although the branch had landed. It now reports AMBIGUOUS, and a rerun reports PRESENT.
• What the pump does not do, by design: decide what is ready. ready-for-agent is the operator’s act of authority. A feeder that picked and labelled its own work was refused by the agent’s permission classifier as an unsafe agent, the same line as Gaia’s “nothing self-authorizes”. What shipped instead is read-only ranking (gaia#157). Today it finds one candidate among 38 open issues, because 34 still carry needs-triage: grooming, not the pump, is the bottleneck.

2026-09-26 — The factory candidate, and the tests nobody ran

• Why watch had gone quiet. It had not hung, it had exited. After issue 108’s worker made no edit, the job ended RECONCILIATION_REQUIRED, and watch stops on that status by design (scripts/github-portfolio-autonomous.mjs:207). The job then held the only slot. Since the issue and its Draft were both closed, retire-closed retired it as ABANDONED after a preview. I made the database backup the documentation asks for after the fact instead of before; nothing was lost.
• Issue 104 produced a real candidate: CANDIDATE_READY, reviewer APPROVE, three files (a pure lane-resume manifest, its document and 17 tests). It stayed local: the factory never publishes.
• The approval did not mean the tests pass. Run with the pinned Node 26.8.1, the candidate failed one of its own tests and the README gate-count test. The cause is structural. The worker prompt says “run the narrowest relevant tests”, but its tools are Read,Write,Edit,Glob,Grep (src/factory-visible-claude.mjs:354), and the prompt adds that “tests are run separately by the supervisor”. No code in src/ runs them. Reported as gaia#163, which proposes a deterministic, host-owned verification step before review rather than a shell for the model.
• The failing test was wrong, not the code. It appended src/extra.mjs after src/resume-manifest.mjs. The module requires artifacts sorted by path, so the observation was refused as malformed before any comparison. Appending tests/extra.mjs keeps the test’s intent; with the README count updated, the candidate passes and was published to Draft gaia#158.

To verify

• factory:agent end to end. It spends a real Claude turn and a real Codex turn on the installed subscriptions. Lesson 4 describes it from src/factory-agent.mjs, its design document and its receipt schema; no claim in that lesson comes from an observed run. What to capture when it runs: the receipt shape with and without a repair, the (not an ETA) progress lines, and whether the reviewer-mutation check ever fires on ignored files in practice.
• Node 26.8.1, the pinned version. Everything here ran on 24.12.0.
• Linux and macOS. The commit protocol is written and tested Windows-first, and the repository says Linux is discovery rather than a gate. The lock-directory approach should behave the same; the Windows-specific release retries would simply not be exercised.
• A second concurrent lane against the same data directory. All the outputs in these lessons came from sequential calls in one shell. The cross-process id-uniqueness property is what the suite asserts, not what I observed.
• The authority-language-detected flag. I saw it fire on “Please merge this.” I have not looked at what it matches, and a heuristic’s false-negative rate is the interesting number.
• Issue 76 after final review. Re-run the full Gaia and Demerzel gates on the exact reviewed commits, publish through normal PRs, and replace the candidate evidence above with immutable commit and receipt links.

Open questions

• The bus has write serialisation and no authentication — trust is positional, so any process able to spawn the server can register as any actor. Lesson 5 shows that being one of two named blockers for the IX integration. What is the smallest actor-identity mechanism that would not turn the bus into a credential store?
• Replay is O(events × actors) on a log that never compacts, and inbox writes an event. A polling lane therefore makes every later call slower. Is there a read path that keeps inbox.polled as evidence without paying for it on every replay — a snapshot plus tail, as the scale document suggests?
• The four-lane number is honest about being unreplicated with real clients. Running that probe needs four simultaneous real agent lanes, which costs real model turns. What is the cheapest experiment that would genuinely discriminate — and would a mix of one real lane and three synthetic ones prove anything, or is that the Node-worker probe again with extra steps?
