Mechanical, behaviour-preserving removal of Stage N / TODO-N / phase (RN) references from comments, doc-comments, service READMEs, the current-state docs (ARCHITECTURE, FUNCTIONAL+_ru, TESTING, UI_DESIGN), config-file comments, and the .fbs/.proto schema comments. PLAN.md / PRERELEASE.md / CLAUDE.md keep the stage history. - Rename the only stage-named identifiers: registerStage8 -> registerSocialOps, registerStage11 -> registerLinkOps (gateway transcode). - Split stage6_test.go: TestEmailLoginFlow -> email_test.go, TestGuestAutoMatchLeavesNoStats (+ provisionGuest) -> account_test.go. - Regenerated proto bindings (push.pb.go, telegram_grpc.pb.go) from the de-staged .proto comments; FB Go/TS bindings unchanged (flatc strips schema comments). go build/vet/gofmt clean across modules; integration typecheck and pnpm check green.

// Global connectivity signal. `online` is false while the app is actively failing to
|
|
// reach the gateway — a unary call retrying after a transport/rate-limit failure, or the live
|
|
// stream dropped. The transport and the live-stream owner report transitions; the UI reads
|
|
// `connection.online` to show the "Connecting…" indicator and to softly disable proactive
|
|
// actions. In mock mode nothing ever reports trouble, so it simply stays online.
|
|
//
|
|
// Recovery is guaranteed by a reachability watcher: while offline it periodically fires a
|
|
// registered probe (a lightweight read) until one succeeds, so the indicator clears even when no
|
|
// other traffic is in flight.
