- internal/db/migrations/: five embedded SQL files containing
the migration SQL previously held as Go string literals.
Files follow the NNN_description.up.sql naming convention
required by golang-migrate's iofs source.
- internal/db/migrate.go: rewritten to use
github.com/golang-migrate/migrate/v4 with the
database/sqlite driver (modernc.org/sqlite, pure Go) and
source/iofs for compile-time embedded SQL.
- newMigrate() opens a dedicated *sql.DB so m.Close() does
not affect the caller's shared connection.
- Migrate() includes a compatibility shim: reads the legacy
schema_version table and calls m.Force(v) before m.Up()
so existing databases are not re-migrated.
- LatestSchemaVersion promoted from var to const.
- internal/db/db.go: added path field to DB struct; Open()
translates ':memory:' to a named shared-cache URI
(file:mcias_N?mode=memory&cache=shared) so the migration
runner can open a second connection to the same in-memory
database without sharing the handle that golang-migrate
will close on teardown.
- go.mod: added golang-migrate/migrate/v4 v4.19.1 (direct).
All callers unchanged. All tests pass; golangci-lint clean.
* web/templates/pgcreds.html: New Credentials card is now always
rendered; Add Credentials toggle button reveals the create form
(hidden by default). Shows a message when all system accounts
already have credentials. Previously the card was hidden when
UncredentialedAccounts was empty.
* internal/ui/ui.go: added ActorName string field to PageData;
added actorName(r) helper resolving username from JWT claims
via DB lookup, returns empty string if unauthenticated.
* internal/ui/handlers_*.go: all full-page PageData constructors
now pass ActorName: u.actorName(r).
* web/templates/base.html: nav bar renders actor username as a
muted label before the Logout button when logged in.
* web/static/style.css: added .nav-actor rule (muted grey, 0.85rem).
- web/static/htmx.min.js: replace placeholder stub with
htmx 2.0.4 (downloaded from unpkg.com). The placeholder
only logged a console warning; no HTMX features worked,
so form submissions fell back to native POSTs and the
account_row fragment was returned as a raw HTML body
rather than spliced into the table. This was the root
cause of account creation appearing to 'do nothing'.
- internal/ui/ui.go: add pgcreds_form.html to shared
template list; add PUT /accounts/{id}/pgcreds route;
reorder AccountDetailData fields so embedded PageData
does not shadow Account.
- internal/ui/handlers_accounts.go: add handleSetPGCreds
handler — encrypts the submitted password with AES-256-GCM
using the server master key before storage, validates
system-account-only constraint, re-reads and re-renders
the fragment after save. Add PGCred field population to
handleAccountDetail.
- internal/ui/ui_test.go: add tests for account creation,
role management, and PG credential handlers.
- web/templates/account_detail.html: add Postgres
Credentials card for system accounts.
- web/templates/fragments/pgcreds_form.html: new fragment
for the PG credentials form; CSRF token is supplied via
the body-level hx-headers attribute in base.html.
Security: PG password is encrypted with AES-256-GCM
(crypto.SealAESGCM) before storage; a fresh nonce is
generated per call; the plaintext is never logged or
returned in responses.
- Added failed login tracking for account lockout enforcement in `db` and `ui` layers; introduced `failed_logins` table to store attempts, window start, and attempt count.
- Updated login checks in `grpcserver/auth.go` and `ui/handlers_auth.go` to reject requests if the account is locked.
- Added immediate failure counter reset on successful login.
- Implemented username length and character set validation (F-12) and minimum password length enforcement (F-13) in shared `validate` package.
- Updated account creation and edit flows in `ui` and `grpcserver` layers to apply validation before hashing/processing.
- Added comprehensive unit tests for lockout, validation, and related edge cases.
- Updated `AUDIT.md` to mark F-08, F-12, and F-13 as fixed.
- Updated `openapi.yaml` to reflect new validation and lockout behaviors.
Security: Prevents brute-force attacks via lockout mechanism and strengthens defenses against weak and invalid input.
- ui/ui.go: add pendingLogin struct and pendingLogins sync.Map
to UIServer; add issueTOTPNonce (generates 128-bit random nonce,
stores accountID with 90s TTL) and consumeTOTPNonce (single-use,
expiry-checked LoadAndDelete); add dummyHash() method
- ui/handlers_auth.go: split handleLoginPost into step 1
(password verify → issue nonce) and step 2 (handleTOTPStep,
consume nonce → validate TOTP) via a new finishLogin helper;
password never transmitted or stored after step 1
- ui/ui_test.go: refactor newTestMux to reuse new
newTestUIServer; add TestTOTPNonceIssuedAndConsumed,
TestTOTPNonceUnknownRejected, TestTOTPNonceExpired, and
TestLoginPostPasswordNotInTOTPForm; 11/11 tests pass
- web/templates/fragments/totp_step.html: replace
'name=password' hidden field with 'name=totp_nonce'
- db/accounts.go: add GetAccountByID for TOTP step lookup
- AUDIT.md: mark F-02 as fixed
Security: the plaintext password previously survived two HTTP
round-trips and lived in the browser DOM during the TOTP step.
The nonce approach means the password is verified once and
immediately discarded; only an opaque random token tied to an
account ID (never a credential) crosses the wire on step 2.
Nonces are single-use and expire after 90 seconds to limit
the window if one is captured.
The package-level defaultRateLimiter drained its token bucket
across all test cases, causing later tests to hit ResourceExhausted.
Move rateLimiter from a package-level var to a *grpcRateLimiter field
on Server; New() allocates a fresh instance (10 req/s, burst 10) per
server. Each test's newTestEnv() constructs its own Server, so tests
no longer share limiter state.
Production behaviour is unchanged: a single Server is constructed at
startup and lives for the process lifetime.
- Added `web/templates/{dashboard,audit,base,accounts,account_detail}.html` for a consistent UI.
- Implemented new audit log endpoint (`GET /v1/audit`) with filtering and pagination via `ListAuditEventsPaged`.
- Extended `AuditQueryParams`, added `AuditEventView` for joined actor/target usernames.
- Updated configuration (`goimports` preference), linting rules, and E2E tests.
- No logic changes to existing APIs.
