The ORCH-058 staging rebuild (check_staging_image_fresh) builds the image with
the task git-worktree as the docker build context. A fresh worktree holds only
tracked files, but the Dockerfile did `COPY data/ ./data/` — and `data/` (the
SQLite dir) is gitignored, so it is absent from that context: `docker build`
failed with exit 1 ("BUILD-STAGING: docker build failed - aborting"), bouncing
the task off deploy-staging back to development in a loop.
The COPY was dead weight regardless: `data/` is always supplied at runtime as a
bind-mount volume (./data:/app/data, see docker-compose.yml) which shadows
anything baked into the image. Replace it with `RUN mkdir -p /app/data` so the
mountpoint exists without depending on the build context.
Regression guard: test_tc08b_dockerfile_does_not_copy_gitignored_data_dir
forbids COPY of any gitignored path (the worktree-context invariant).

Extend pipeline responsibility past deploy->done: after the terminal
transition for an applicable repo, arm a ~15min observation window that
probes prod and reacts to a degradation the restart-time health-check
missed ("green deploy, red prod").
- src/post_deploy.py: new leaf module (config + lazy qg/db only).
Sentinel-file restart-safe state (.post-deploy-state-<repo>/<wi>/),
no DB migration. probe_signals/classify/decide_action/run_rollback,
all never-raise.
- Reserved-agent job `post-deploy-monitor` (no-LLM, Variant B, calque of
deploy-finalizer): self-requeues each tick via enqueue_job.
- Deterministic classify: DEGRADED iff >= fail_threshold consecutive
health failures OR window 5xx ratio > 5xx_threshold; fail-safe HEALTHY.
- Self-hosting invariant (BR-5/AC-8): a tick NEVER restarts the prod
orchestrator container -> orchestrator is ALWAYS ALERT_ONLY.
- Conditionality (ORCH-35/36/43/58): kill-switch + CSV repos, empty ->
self-hosting only.
- QG_CHECKS / STAGE_TRANSITIONS / schema unchanged (AC-12).
- Docs: CHANGELOG, CLAUDE artefact list (16-post-deploy-log.md),
architecture README, .env.example (ORCH_POST_DEPLOY_*).
