- Around line 25-28: Update the user setup command in the Dockerfile so it
rejects LOCAL_UID=0 before creating workstream, then permits duplicate non-root
UIDs with useradd’s non-unique option. Preserve the existing group setup and
ensure UID 0 cannot reach the USER workstream runtime configuration.
Review comments at @docs/engineering/local-pilot.md:
- Around line 92-96: Update the authenticated request examples in the guide to
avoid passing bearer tokens in curl arguments. Add a helper that writes the
Authorization header to a mode-600 temporary file, uses it with curl, and
removes it afterward; route actor_id and every other authenticated request
through this helper, including grant operations using ADMIN_TOKEN.

43-45: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low valueNarrow the ownership change to avoid copying the source tree again.
COPY backend/ ./places the source in an earlier layer. The later recursivechowncan add copy-up work for that source tree. Compose then bind-mounts./backendover/workspace/backend, so this ownership change has no normal Compose runtime benefit.
uv synccreates/opt/venvin the sameRUNinstruction. Its ownership change does not duplicate a previous virtual-environment layer. Retain it to preserve the current non-root behavior. UseCOPY --chownfor the copied source instead.Suggested fix
-COPY backend/ ./ +COPY --chown=${LOCAL_UID}:${LOCAL_GID} backend/ ./ RUN --mount=type=cache,target=/root/.cache/uv \ uv sync --locked --extra agents --extra dev \ - && chown -R "${LOCAL_UID}:${LOCAL_GID}" /workspace /opt/venv + && chown -R "${LOCAL_UID}:${LOCAL_GID}" /opt/venvThis is an optional build optimization. No explicit project requirement for image size or build time was found.

Problem and resulting behavior
The repository's local Compose path had an optional API with storage disabled and no durable worker or scheduler. This change provides a checkout-isolated six-service base: API, the existing prefork Celery worker, Celery beat, PostgreSQL, Redis and source-built MinIO. Every published port and the Compose project name come from an ignored root
.env; containers, network, data volumes and bounded scratch stay project-scoped.API, worker and beat share the canonical
s3_compatibleartifact configuration. API startup idempotently creates and verifies only the checkout-local MinIO bucket. Local identities use the existing Flow-HMAC token contract with empty role claims, then gain authority only through the existing trust-root and grant operations.Scope
This PR does not add migrations, routes, authority contracts, runner/model-proxy services, frontend/cloud bootstrap, a fabricated approved guide, or a complete-pilot claim. The existing solo-worker guide drill is unchanged.
Current-head review repairs
useradd --non-uniquenow supports a colliding non-root host UID, while an explicit pre-creation guard rejects UID zero.status. The helper now usescurl_status; Bash and zsh both preserve curl status and remove the header on success and failure.Verification on

Its only new note is an explicitly optional source-layer ownership optimization, with no required image-size/build-time criterion. The verified runtime ownership behavior remains intact.Historical Linux live-stack evidence
The six-service Linux drill and all prior canonical checks passed on the earlier reviewed
115df4b0source. That evidence remains historical after this push; it is not presented as exact-head hosted CI. The unchanged Compose/runtime topology reached healthy API, prefork worker concurrency two, beat, PostgreSQL, Redis and MinIO; Celery returnedpong. Existing public operations created five distinct humans, all six fixed service actors, two projects and scoped grants. A real 855-byte PDF upload was verified through MinIO and survived shutdown/restart with the same digest. Forced worker and beat restarts retained the setup identity and schedule. Two isolated six-service projects ran together, and stopping/disposal of one did not affect the other.Without a provider credential, the worker durably reserved setup and stopped before model dispatch. No successful provider-backed compilation was claimed.
Remaining issue evidence
No macOS host was available. Docker Desktop/macOS is documented as the supported path, with runtime, file-sharing, sleep/resume and architecture proof explicitly unverified.
No real provider key or activated approved guide was available. A provider-backed successful guide compilation and activated-guide task-release denial remain issue-level evidence gaps. This bounded local-runtime PR must not close #488 or imply the whole pilot is delivered.
