R6(a): de-stage code, docs, READMEs; split stage6_test
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.
