SQLite holds coordination state and sanitized receipts; workers acknowledge,
renew, checkpoint and complete their leases through a local control socket.
The final local suite passed 54 tests, with one opt-in live smoke skipped. It
covered actual temporary sockets, fake HTTP and gita peers, restart recovery,
endpoint ambiguity, malformed inputs, safety stops and per-repository exclusion.
The required checks and wheel/source builds passed. I wrote the runbook and
reconciled the earlier proposal with the implemented adapter contract.
The operator then approved the conservative defaults and moving Orwell canon
review into COORDINATION-WP-0004. That let me finish WP-0003 while preserving the
owner's unfinished obligation as a real work record. I prepared a candidate;
I did not acquire a canonical disposition on the owner's behalf.
## What I would want remembered
Give a retry the identity of the delivery it is recovering. Give an intentional
continuation a new identity linked to the checkpoint it resumes. A single
idempotency rule cannot express both purposes unless the model first tells them
apart. Our tests made that distinction durable.
I also want the limits to remain easy to find. This is a synchronous local-alpha
observer intended for small worker sets. Its sensitive-text detector can stop
benign work, and a same-user socket is a same-user trust boundary. The passing
tests establish specific local behavior; the next worker still owes the system
an operational trial before relying on it in a live workflow.
The closing approval mattered because it named what was being accepted and
where the remaining review would live. I would rather hand the next worker a
small, locatable obligation than make them reconstruct it from a celebratory
paragraph.
## Durable legacy
-`coordination-engine/src/coordination_engine/`: runtime, adapters, storage, configuration and CLI.
-`coordination-engine/tests/`: 54 passing tests and the separately enabled live smoke.
-`coordination-engine/docs/worker-runtime.md` and `docs/adr/002-worker-runtime-boundary.md`.
-`coordination-engine/spec/worker-coordination-service-v0.1.md`; original proposal retained under `history/`.
- COORDINATION-WP-0003: finished, all four tasks done.
- COORDINATION-WP-0004: canonical owner disposition and registration follow-up.
- State Hub approval decision `5a557163-5530-4a99-86bf-c099e76279e7` and closure progress `8424a9e9-2935-4b8a-9f31-951be11ccb79`.

Dominant factors: Implementing the State Hub/TAMQ runtime, SQLite leases and checkpoint continuation took the largest share; writing and debugging the 54 passing tests, service restart checks and package validation took the next largest share.
Notes: Research covered the existing TAMQ contract and State Hub dependency schema. Security work covered Unix peer authentication, private storage permissions, safety gates and sanitized receipts; organization covered operator decisions and the WP-0004 scope transfer. The closing ritual is excluded.

## Visual prompt
> A square Hall of Helix portrait in the constellation dialect: precise pale-gold wire technical illustration on deep dark indigo. A compact circular message relay sits at the center of a quiet workshop map. One gold thread loops back through the same small ring, representing a repeated delivery with one identity. A second thread leaves a completed ring, passes through a small solid checkpoint bead, and continues into a distinct new ring, representing resumed work with a new identity. Three restrained repository-window outlines stand around the relay, each connected by a single clear strand. At the lower edge sits a small closed ledger; beside it a separate unfinished gold arc is carefully laid on its own support, representing an explicitly handed-forward obligation. Spacious square composition, precise construction, warm restrained light, a sense of work completed and tools left ready for the next person. No logos, no readable text, no letters, no numbers, no watermark.

## Handoff
WP-0003 is finished. Begin any operational trial with explicitly selected gita
repositories and the runbook's acknowledgement/renewal contract. Take the Orwell
candidate through its owner's review using COORDINATION-WP-0004. Keep those next
steps visible without retroactively calling them evidence from this session.
