F5b of the sc-forge ops slice: the operating surface.
Structured logs (log.rs). One JSON object per line on stderr (time, severity, message, the Cloud Logging keys), every eprintln! of the server converted. An access log line per request: method, path without query, status, time to the response head, client address. No headers, bodies or query strings; strings are cut at 512 bytes. Health probes that succeed are not logged. Hook messages to a pushing client and operator CLI output stay plain text.
SIGTERM drain.--shutdown-timeout (default 30). The listener closes first, idle keep-alive connections close at once (they used to hold the drain for the whole deadline; hyper graceful shutdown), requests in flight finish, git processes still running are cancelled, exit 0. The signal handlers are now installed before the "listening" line: a SIGTERM right after it used to kill the process instead of draining.
Bind-gate process tests (0.0.0.0, [::], private, v4-mapped loopback refused; the two flags allow; loopback needs none).
Container image (crates/forge/Dockerfile: trixie git 2.47, digest-pinned bases, uid 10001, no sshd), docker/smoke.sh (boot, healthz, create, clone, docker stop exits 0) and an advisory sc-forge image CI job that runs only when the forge changes.
Operations guidedocs/FORGE-OPERATIONS.md: serving, stopping, logs, maintenance, cgroup starting points (marked as estimates), backup, upgrades. Threat model, spec and ROADMAP updated.

Verification
cargo test -p scl-forge and clippy green; 7 new process tests in e2e_ops.rs (idle keep-alive, request in flight, stalled request, bind gate x3, logs without secrets).

Summary by CodeRabbit
New Features
Added a Docker image for running Forge with persistent data storage.
Forge now provides structured JSON logs, including request status and timing. Successful health checks and query strings are omitted from access logs.
Added a configurable shutdown timeout. Forge stops accepting new connections and allows active requests to finish during shutdown.
Improvements
Non-loopback listening requires an explicit proxy or plaintext option.
Idle connections close during shutdown.
Documentation
Added operational guidance for setup, security, logging, backups, maintenance, and upgrades.
No actionable comments were generated in the recent review.

Walkthrough
This change adds structured JSON logging and request access logs to Forge, configurable signal-driven shutdown with integration tests, and a container image with a smoke test and conditional CI job. It also adds operations documentation and updates the P38 roadmap entry.
Adds JSON log rendering, UTF-8-safe clipping, queued stderr emission, and INFO, WARNING, and ERROR helpers. Existing diagnostics in Forge paths now use the logger.
Request logs include the method, query-free path, status, response-head latency, and resolved source. Successful health probes are omitted. The serve command accepts a shutdown timeout, and the server closes its listener before gracefully shutting down connections. Tests cover request logs, bind restrictions, and shutdown behavior.

Adds a Forge image and a smoke test for health, repository creation, cloning, and shutdown. The advisory CI job builds and tests the image when selected paths change.

Merge Risk: Minimal · up to d2383
The logging correction preserves the current event, and the container smoke test can check shutdown successfully. The change is mergeable after normal checks.
Security architecture risk: Low · up to 52283
The inspected changes preserve public-bind protections and introduce no demonstrated privilege expansion. Logging deliberately favors availability over guaranteed delivery, while shutdown still depends on startup recovery for some interrupted work. Production network placement, mounted-volume ownership and recovery completeness remain unverified.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The log queue and shutdown controls are shared across a Forge process, so log saturation and drain behavior affect the instance rather than one repository. This does not itself grant access to other repositories or expand authorization.
Trust Boundaries and Controls
observed — Non-loopback plaintext binds still require an explicit operator override. Logged client identity uses the existing resolver, which accepts forwarded addresses only from configured trusted peers. The container neither starts serving by default nor adds a Git safe-directory trust override.
Resilience and Maintainability Implications
observed — The 4096-entry queue uses nonblocking enqueue and counts rejected records, protecting request handling from a stalled stderr consumer. Loss warnings require subsequent enqueue capacity, and exit flushing waits at most two seconds. These diagnostics therefore provide best-effort observability, not durable audit delivery.
Hardening Proposals
proposed — If production incident detection depends on these records, consider exposing log-loss health independently of the same queue so sustained saturation cannot also suppress its warning. This is a hardening option, not an observed vulnerability.

Keep repository identifiers in structured log fields.
These macros always pass None for fields. Calls such as maintenance::run_pass therefore put repo_id only in message. Operators cannot filter repository failures by a repo_id field. Add a macro form that accepts fields, and use it for repository diagnostics. Based on learnings, put variable log data in structured fields rather than formatted message text.
