- backend + gateway multi-stage distroless Dockerfiles; the gateway embeds and
serves the SPA at / and /telegram/ via go:embed (committed dist placeholder,
real build baked in by the image's node stage)
- deploy/docker-compose.yml: backend + gateway + Postgres + Telegram connector
(VPN sidecar) + OTel Collector + Prometheus (15d) + Tempo (72h) + Grafana,
fronted by a caddy owning a single /_gm Basic-Auth (admin console + Grafana
subpath); inter-service on a private network, only caddy on the edge network
- new metrics: backend accounts_created_total{kind} (robots excluded) and an
in-memory gateway active_users{window=24h,7d} gauge
- CI: single .gitea/workflows/ci.yaml (unit/integration/ui + a gated test-contour
deploy) on the new feature/* -> development -> master branch model; the old
go-unit/integration/ui-test workflows are folded in; the connector-scoped
compose is retired (superseded by deploy/)
- docs: ARCHITECTURE §11/§12/§13, root + gateway READMEs, CLAUDE.md branching,
PLAN.md (stage 16 done + refinements + Stage 17 forward-notes)
