- pkg/telemetry: shared OTel provider bootstrap (none/stdout/otlp + W3C
propagators + Go runtime metrics); backend/internal/telemetry becomes a thin
facade keeping its gin middleware.
- Telemetry parity: gateway and the Telegram connector gain telemetry runtimes
and config (GATEWAY_/TELEGRAM_ SERVICE_NAME + OTEL_*); otelgrpc instruments the
backend push server, the gateway's backend+connector clients and the connector
server. Default exporter stays none (collector/dashboards are Stage 14).
- Operational metrics (variant attribute on game-scoped ones): game_replay_duration,
game_move_validate_duration, games_started_total, games_abandoned_total,
game_cache_active, chat_messages_total{kind}, gateway edge_request_duration.
Wired via the SetMetrics setter pattern (default no-op meter).
- TODO-3: account.GuestReaper deletes guests with no game seat past
BACKEND_GUEST_RETENTION (default 30d, swept every BACKEND_GUEST_REAP_INTERVAL).
- Tests: pkg/telemetry exporter selection; game/social/edge metric recording via
a manual reader; config (otlp accepted, guest knobs); inttest guest reaper.
- Docs: PLAN.md re-scopes Stage 12 and adds Stage 13 (alphabet-on-wire) + Stage 14
(CI/deploy) with the agreed dictionary-versioning resolution; ARCHITECTURE 11/13,
TESTING, the three READMEs and FUNCTIONAL(+ru) updated.
