Why: The login recovery contract leftovers and KTD12/KTD14 require: concurrent same-name account creation must not overwrite the winner, first-admin bootstrap must serialize across processes, the redeem endpoint backoff must be shared across instances, revoked API keys must close established SSE streams, and CLI credentials need an env-DSN path plus a non-interactive 0600 file delivery mode. Evidence: go test ./... green; new tests cover 16-way concurrent create (1 win/15 conflict, winner credentials intact), 8-way concurrent bootstrap (single admin, refuse takeover after), redeem guard shared across two store handles on one DB, SSE stream closed after key revocation within the recheck window, and HTTP 429 after the failure cap (SELF worktree run; CI is the GATE, PG via test-pg). Impact: Migration v29 (redeem_attempts); CreateAccount becomes a single-row INSERT with unique-violation conflict; BootstrapFirstAdmin advisory-locks (PG) / rechecks (SQLite) and commits admin+key+audit in one transaction; SSE revalidation covers API-key streams; redeem backoff moves to the shared DB; CLI gains AGENT_SYSTEM_DSN fallback and --out file delivery for create/reset-password/issue-login-key/ bootstrap-admin.
