- 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.
- 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.
* Rewrite .golangci.yaml to v2 schema: linters-settings ->
linters.settings, issues.exclude-rules -> issues.exclusions.rules,
issues.exclude-dirs -> issues.exclusions.paths
* Drop deprecated revive exported/package-comments rules: personal
project, not a public library; godoc completeness is not a CI req
* Add //nolint:gosec G101 on PassphraseEnv default in config.go:
environment variable name is not a credential value
* Add //nolint:gosec G101 on EventPGCredUpdated in model.go:
audit event type string, not a credential
Security: no logic changes. gosec G101 suppressions are false
positives confirmed by code inspection: neither constant holds a
credential value.
