Why: Concurrent password changes, recovery key reissue, and session admission could accept retired credentials or omit rejected audits.
Evidence: Local Go vet and full tests passed; real PostgreSQL store suite, deterministic interleavings, and two-process contention passed with SELF receipts.
Impact: Account writes and session admission serialize per owner; stale sessions fail closed; checked rejections carry an audit row.
Refs: Agent-System-Dev #486; Agent-System-Backend #185; merge queue Issue #518
Why: Deliver U7 account transactions and audit without losing main auth_version, restricted-session, project or migration behavior.
Evidence: SELF go vet and all Go tests passed; isolated PostgreSQL store tests, 20 repeated two-process admission rounds, and real SIGTERM/SIGKILL persistence passed. Original failures remain in receipts; exact-head CI and independent Review follow.
Impact: Adds schema v31, noncreating account CLI opens, preflight credential output, same-transaction audit, and bootstrap admission guards. No live database touched.
Refs: Backend PR #185; Dev PR #486; original U7 r2 account specification; 2026-10-14 Root takeover
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.
Refs: docs/svc-deploy/2026-10-13-login-recovery-contract.md leftovers;
proposal r2 KTD12/KTD14/R5/R11.
Why: The login recovery contract (2026-10-13) requires admin-issued
one-time keys, in-transaction revalidation of restricted sessions, a
login race guard, and audited password writes; the previous
implementation validated sessions outside the change-password
transaction and let stale password verifications create sessions.
Evidence: go test ./... green (SQLite); store tests switch to
openTestStore so the CI test-pg job covers real PostgreSQL, including
100-way concurrent redeem single-winner and auth-version race cases
(SELF, local run).
Impact: New migration v28 (users/sessions.auth_version,
account_events). New admin endpoints POST/GET
/api/admin/users/{owner}/login-keys and DELETE
.../login-keys/{id}. Login binds session creation to the verified
auth version and creates restricted sessions for must-change accounts;
redeem gains per-IP backoff; cookies gain Secure under TLS; active
change-password and admin/CLI resets become single transactions that
bump auth_version, revoke keys and sessions, and write audit events.
Refs: modules/documents/docs/proposals/2026-10-12-svc-unified-deploy-and-login-key.md r2; Dev task feature/svc-login-recovery-flow
Why: creating an account and its activation key, and changing a password, were separate commits, so a crash could leave a user without a key or a new password with a still-valid login key.
Evidence: SELF go test ./internal/store including TestConcurrentCreateOneWinner, TestPasswordChangeIsAtomic, TestOpenExistingDoesNotMigrateOrCreate, and TestBootstrapRefusesExistingBusiness. PostgreSQL cases are NOT_RUN locally.
Impact: strict insert returns ErrConflict instead of overwriting. Account CLI opens an existing database without migrating. --dsn and --password still work and warn. capabilities --json does not touch the database.

Why: passwordless activation/recovery must redeem only into a
set-password session; account ops must not create empty stores.
Evidence: SELF go test store/server login-key and OpenExisting cases.
Impact: auth middleware gates; CLI user create defaults to activate key.
Refs: docs/svc-deploy/u4-one-time-login-key.md
Co-authored-by: Cursor <cursoragent@cursor.com>
Why: user create/reset-password and conversation flag updates wrote 1/0
literals and boolInt ints into BOOLEAN columns; SQLite tolerates it,
PostgreSQL rejects with 42804. The 10-04 user create on pg1 failed midway
(empty password_hash, is_admin=f), and password reset, user list (bool
scanned into int) and login (GetUserAuthState scan) were all broken on
the postgres tier.
Evidence: store tests green; against the live pg1 the fixed CLI completes
user reset-password and user list (isAdmin=true, mustChangePassword=true,
hasPassword=true).
Impact: auth/account management and conversation list/flag paths work on
postgres; SQLite unchanged (0/1 converts via driver.Bool). No schema
changes.
Refs: dev-repo PR for gitlink bump (feature/store-pg-bool-dialect)
Why: the user ruled out self-registration (2026-09-30): accounts are
created only by admins who set an initial password; first login (and
first login after any admin reset) must force a password change.
Evidence:
- migration v10 auth_accounts (users password/must_change/is_admin +
sessions table; upgrade test walks v1<->v10 both directions).
- argon2id hash/verify with PHC encoding; store tests cover hash
roundtrip, duplicate-owner conflict, must-change lifecycle, session
keep/except semantics.
- e2e TestAdminAccountFlow: static login page reachable without auth,
wrong password 401, login sets HttpOnly cookie + mustChangePassword,
admin creates user (409 on duplicate), non-admin create 403, forced
change clears flag and old password dies, admin reset revokes sessions
and re-arms forced change, API-key channel untouched, 5-fail backoff
429, logout kills session. Full go test ./... green.
Impact: middleware now accepts Bearer key OR session cookie and exempts
static + /api/auth/login (also fixes the latent case where the login
page itself could 401). Embedded no-auth mode unchanged.
Refs: proposal 2026-09-30-ui-redesign-and-auth.md section 5 (admin-issued
variant, user decision 2026-09-30)
Why: backend main pinned core 019617e (unfetchable post-migration) and the
store List* functions returned nil slices that encode as JSON null, which
crashed the frontend nav with .map on null (the 2026-09-30 white-screen).
Evidence: go test ./... across all packages; store regression
TestEmptyListsSerializeAsEmptyArrays asserts [] for empty project lists.
Impact: all 17 store list sites now initialize empty slices; build-blocker
core pin resolved; frontend no longer receives null for empty lists.
