Land the offline-model redesign (ANDROID_PLAN.md O1-O7): replace the explicit offline toggle with a single detected net-state machine, unify the lobby, and add a two-tier client-version gate. Contour-safe: both version vars empty => dormant, the wire change is additive, so web/pwa/vk/tg behaviour is unchanged unless the gate is deliberately configured.
O1 net-state reducer (test-first). O2 store + wiring (connection/offline shims; +@capacitor/network). O3 remove the offline toggle + migrate the pref. O4 two-tier gate: hard update_required degrades to an offline Update/Play-offline notice (not terminal); soft GATEWAY_RECOMMENDED_CLIENT_VERSION -> X-Update-Recommended nudge. O5 unified lobby (device-local + greyed-from-cache server games; self-set identity; closes G-step-0). O6 create flows (with-friends online/offline segment + offline dict guard). O7 docs.
Telegram/VK stay online-only (contour review): the offline model is channel-gated via offlineCapable() (native + plain web; false in the mini-apps). offlineMode.active is hard-gated on it, so the whole model (blue chrome, unified/greyed lobby, transport kill switch, device-local vs_ai/hotseat create) stays inert in Telegram/VK regardless of the detected net state (closing a version-lock path that could have flipped them offline); and New Game's with-friends hides the online/offline segment there, leaving the remote invite alone. ARCHITECTURE already declared "Telegram/VK are exempt" - this makes the code match.
Deploy/CI: wire the version gate through the deploy (GATEWAY_MIN_CLIENT_VERSION + GATEWAY_RECOMMENDED_CLIENT_VERSION as plain unprefixed vars via compose + ci.yaml + prod-deploy.yaml + write-prod-env.sh + .env.example) so the gate is live when set (test-contour commit-hash version fails open; empty => dormant). Disable the manual android-build CI workflow for now (rename .disabled). Bump the app bundle budget 127->130 KB for the added always-loaded wiring. Fix the UI Docker stage (gateway/Dockerfile): install --ignore-scripts so the Alpine/musl SPA build no longer tries to native-build sharp (a local android:assets tool, unused in the image); esbuild's binary is an optional dep so Vite still builds.
Tests: gateway go green (two-tier gate over a real HTTP handler); docker build of the landing + gateway targets green locally; compose --no-interpolate confirms the gateway env; two new telegram.spec.ts e2e (offline signal keeps the chrome online + quick-match opponent choice visible => server enqueue; with-friends shows no pass-and-play), RED-verified; svelte-check 0/0, vitest 617, e2e 248 (chromium + webkit), build + bundle-size 127.8/130.
Introduce a minimum-supported-client gate so a future incompatible wire change
can turn away installed builds too old to speak it, cleanly, instead of letting
them crash on decode. It rides the outermost stable layer (an HTTP header), never
the FlatBuffers payload.
Gateway:
- New internal/clientver: dependency-free parse + compare of the leading
MAJOR.MINOR.PATCH (a git-describe suffix is tolerated).
- GATEWAY_MIN_CLIENT_VERSION config (empty => gate dormant; validated at load).
- connectsrv checks the X-Client-Version header before decoding the payload:
Execute returns result_code="update_required" (before the registry lookup),
Subscribe returns FailedPrecondition. It fails open on an absent or garbled
header — the header is a client-controlled compatibility signal, not an access
control.
Client:
- Attach X-Client-Version on every call.
- A terminal update.svelte.ts store + a non-dismissable UpdateOverlay (native
opens VITE_STORE_URL, web reloads); retry.ts maps FailedPrecondition to the
update_required sentinel; a mock __update hook drives the e2e.
Wire-additive and contour-safe: no FBS/proto regen, no schema migration; the gate
stays dormant until GATEWAY_MIN_CLIENT_VERSION is deliberately set, so web / VK /
Telegram behaviour is unchanged. The silent reconciliation seam is deferred to the
offline-first work (its only caller). Tests: Go clientver/config/connectsrv gate
tests, retry.test.ts, Playwright update.spec.ts.
- gateway/Dockerfile gains a `landing` target: caddy:2-alpine + the shared
Vite build (identical build args keep the ui stage a single cached build);
the gateway target drops landing.html from the embed.
- The contour caddy routes /app/, /telegram/ and the Connect path to the
gateway; the catch-all — the landing at / and any stray path — goes to the
new landing service, so junk traffic is absorbed by static file serving.
- deploy/landing/Caddyfile mirrors the webui caching (immutable assets,
no-cache shells) and falls back unknown paths to the landing shell.
- The gateway's / now 308-redirects to /app/ (keeps a local no-caddy run
usable); webui placeholder landing.html removed.
- CI deploy probe checks both / (landing) and /app/ (gateway).
Verified: both images build; the landing container serves landing.html at /
(no-cache) with junk-path fallback; the gateway image redirects / to /app/
and carries no landing content.
- GATEWAY_MAX_BODY_BYTES (1 MiB): connect WithReadMaxBytes + http.MaxBytesReader
on the public mux; explicit http2.Server MaxConcurrentStreams/IdleTimeout and
an http.Server ReadHeaderTimeout (R2 report follow-up).
- gateway_rate_limited_total{class} counter, Debug per rejection, a rejection
tracker drained every 30 s into a Warn summary per key and a report POST to
/api/v1/internal/ratelimit/report (feeds the admin view + auto-flag).
- The dead AdminPerMinute/AdminBurst policy now guards the /_gm mount (429),
ahead of its Basic-Auth.
- resolve() logs the cause of infra session-resolve failures at Warn (the
transient unauthenticated dips from the R2 run); unknown tokens stay silent.
