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:.

"""``python3 -m leetcode_coach.relay``: the systemd unit's entry point.

Logs to stderr (the journal) at INFO; SIGTERM stops taking requests and
|
|
lets the running one finish (the unit's ``KillMode=mixed`` spares the claude
|
|
child meanwhile). The phone path signs in as crdt_sync app
|
|
``leetcode_coach_relay`` via `guard_bridge.phone_id_token`, which heals from a
|
|
sibling app's session; ``$LEETCODE_COACH_RTDB_URL`` skips sign-in (tests).
