Exposure: --grpc default flipped from 0.0.0.0 to 127.0.0.1 (the API is unauthenticated by design; auth belongs to the transport), Unix-domain- socket support (--grpc unix:///run/secs_gemd/api.sock = zero network surface), SECURITY.md documents the contract and ch42 gained a "Running it in production" section (which also documents the HSMS-SS single-session assumption). Graceful shutdown: SIGTERM/SIGINT land on an asio::signal_set on the io thread, which nudges grpc Shutdown with a 2s deadline (cancels open Subscribe/WatchHealth streams); Wait() returns on the MAIN thread, which stops the engine (rt->stop() joins the io thread, so it must not run on it). Exit 0, journal-safe, the in-code TODO is gone. --spool-dir added so host-bound events survive daemon restarts. Observability: --metrics serves Prometheus gauges secsgem_link_selected / secsgem_control_state / secsgem_spool_depth, wired via the Phase-0 add_link_observer/add_control_state_observer hooks + io-thread sampling. Deployment: deploy/secs_gemd.service — hardened systemd unit (DynamicUser, ProtectSystem=strict, StateDirectory for the spool, UDS for the API, TimeoutStopSec aligned with the graceful-shutdown window). Enforcement: tools/check_daemon_ops.sh proves all three operational claims (unix-socket gRPC accepts, all gauges present on /metrics, SIGTERM -> exit 0 + clean-stop log) — green; wired into tools/run_interop.sh (now 11 steps) and CI. CI python-interop lane also gained the pyclient and spool-restart steps, so every harness now runs in CI. TODO sweep: the shutdown TODO is fixed; the four remaining TODOs (nested list formats, C2-as-text, U8>2^63, CONNECTED link state) are deliberate deferred edge cases, each marked in code with context. Daemon suite re-verified green (175 assertions). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# Phase E operational checks for secs_gemd, run inside the builder image:
|
|
# 1. serves the gRPC API over a UNIX DOMAIN SOCKET (no TCP exposure),
|
|
# 2. exposes Prometheus metrics (link/control-state/spool gauges),
|
|
# 3. shuts down GRACEFULLY on SIGTERM (exit 0, "stopped cleanly").
|
|
# Exit 0 = all three hold.
