Standalone utils subproject (pyproject, pre-commit, CI, install.sh,
README with the library API). It no longer imports leetcode_guard:
guard_bridge resolves the three read-only calls on demand.
Q5: SQL problems skip req: and ask for an OUTPUT SHAPE (columns,
rows, grouping) before code; algorithm problems keep req:.

leetcode_coach.relay implements DOCS-coach-relay.md: one paced serial lane
(1 start / 3 s, 5 queued, done-map re-answers a rid), the loopback API on
127.0.0.1:8777 (Host check, JSON only, 16 KiB), the RTDB request/result/
state/chat/heartbeat mirror over SSE with 60 s rescans and 24 h cleanup, the
five-step state machine derived from the session log, graders (steps 1/5
haiku -> Ollama, fail open "unverified"; step 2 through PhaseGate.screen;
step 3 mechanical against answer_key.json), the CLI's sonnet chat with the
log in the child env and the local hand-over, run-code on node --permission,
and step 4 through the harvester's read-only fetch_recent_ac once a minute
(three-valued: unknown is never "not yet").
New log events session_start/grade/chat/session_end land in session_log,
_coach_log and _well_formed together; the snapshot rows gain grades and
accepted (_coach_grades). A forced step-2 grade opens code (phase.req_state).
leetcode-coach-relay.service + an install.sh step (not run).
Contract fixes in the same commit: step 3 counts also_accepted and combined
entries' parts, step-2 grade events and the force event shape, next_step,
per-call model caps instead of a 280 s watchdog, heartbeat on busy changes,
the statement fetched in-process, enable + restart on reinstall.
