DevvynandClaude Opus 5 66eb01ba8f feat(docker): restore in-app self-update in the Compose deployment
Codeman running under docker/docker-compose.yaml lost the ability to update
itself from App Settings -> Updates. The image had no .git (excluded by
.dockerignore), so the install reported as "unknown"; there was no init system
for detectSupervisor() to find; the runtime stage had neither devDependencies
nor a build toolchain; and a pull into the baked /opt/codeman would have landed
in the container's writable layer and been discarded by the next `up`.

Restore it through configuration rather than a second updater, so the release
channel, auto-stash, status file and boot reconcile are all reused unchanged:

- The checkout Compose builds from is bind-mounted over /opt/codeman, so the
  update's git checkout and rebuild land on the host and survive recreation.
- The restart is the server exiting; `restart: unless-stopped` relaunches the
  container on the new dist/. This is the one supervisor whose updater does NOT
  outlive the restart, which is safe only because the terminal "restarting"
  marker is written first.
- node_modules and dist are named volumes over the bind mount, so
  container-compiled native modules never enter the host checkout.
- The runtime image keeps devDependencies and gains python3/make/g++, since
  `npm run build` is tsc + esbuild and node-pty has no Linux prebuild.

An in-place container update applies code only, because a restart reuses the
existing image and config. evaluateEnvironmentGate() reads the target release's
own files with `git show <tag>:<path>` and refuses when server.Dockerfile or
docker-compose.yaml changed, when .env.example gained keys the user's .env
lacks, or when the restart policy would not bring the container back. The
missing-key check matters most: Compose resolves an unset ${VAR} to the empty
string and starts anyway, so a new required setting would otherwise arrive as a
silently blank variable. Every unknown fails open, and the gate is re-evaluated
server-side on POST /api/system/update.

The four global agent CLIs are pinned, because an unpinned CLI bump is the one
environment change no diff-derived gate can see; pinning turns it into a
Dockerfile change the gate already detects.

Adds test/docker-compose-env-parity.test.ts as the merge-side guard (every
compose ${VAR} has an .env.example entry and the reverse) and
test/docker-self-update.test.ts for the pure gate decisions.

Restore in-app self-update for the Docker Compose deployment.

App Settings → Updates now works in the container, using the same updater, status file and progress UI as a bare-host install. The Compose file mounts the checkout it builds from at /opt/codeman, so an update's git checkout and rebuild land on the host and survive container recreation, and the restart is the server exiting — restart: unless-stopped relaunches it on the new build.

An in-place container update applies application code only, since a restarted container reuses its existing image and configuration. The updater therefore refuses a release that changes docker/server.Dockerfile or docker/docker-compose.yaml, or that adds keys to docker/.env.example the user's .env has no value for, naming what changed and pointing at docker/Start-Codeman.sh on the host. It also refuses when the container's restart policy would not bring it back. The missing-key check matters most: Compose resolves an unset ${VAR} to the empty string and starts anyway, so a new required setting would otherwise arrive as a silently blank variable.

Supporting changes:

  • The runtime image keeps devDependencies and gains python3/make/g++, so npm install and npm run build can run inside the container. This makes the image larger; that is the cost of updating in place.
  • Build artefacts live in codeman-node-modules and codeman-dist named volumes so container-compiled native modules never land in the host checkout.
  • The four global agent CLIs are pinned, so a release needing newer CLI behaviour becomes a Dockerfile change the environment gate can detect.
  • docker/Start-Codeman.sh records the Dockerfile and compose fingerprints the container was created from, which is the baseline the gate compares against.
  • New CI guard: test/docker-compose-env-parity.test.ts fails when a compose variable has no .env.example entry, or the reverse.
