Link an email (confirm-code) or Telegram (web Login Widget) to the current account; if the identity already has its own account, merge the two into the one in use (the current account is primary, except a guest initiator whose durable counterpart wins). The merge runs in one transaction (internal/accountmerge): stats + hint wallet summed, paid_account ORed, identities/games/chat/complaints transferred, friends/blocks de-duplicated, the secondary kept as a merged_into tombstone so a shared finished game's no-cascade FKs hold; a shared active game blocks the merge. - migration 00009: accounts.paid_account, merged_into, merged_at (+ jetgen) - internal/link orchestrator; session.RevokeAllForAccount on merge - connector ValidateLoginWidget RPC + loginwidget HMAC validator - edge ops link.email.request/confirm/merge, link.telegram.confirm/merge; supersedes the Stage 8 email.bind.* surface (request never reveals 'taken' before the code is verified, so a probe cannot enumerate addresses) - UI Profile link section + irreversible-merge dialog; Telegram web sign-in - focused regression tests (merge core, guest inversion, active-game refusal, finished-shared-game kept), gateway transcode + connector + UI codec/e2e - docs: PLAN, ARCHITECTURE 3/4/9, FUNCTIONAL(+ru), module READMEs
