Phase 14: Full WebAuthn support for passwordless passkey login and
hardware security key 2FA.
- go-webauthn/webauthn v0.16.1 dependency
- WebAuthnConfig with RPID/RPOrigin/DisplayName validation
- Migration 000009: webauthn_credentials table
- DB CRUD with ownership checks and admin operations
- internal/webauthn adapter: encrypt/decrypt at rest with AES-256-GCM
- REST: register begin/finish, login begin/finish, list, delete
- Web UI: profile enrollment, login passkey button, admin management
- gRPC: ListWebAuthnCredentials, RemoveWebAuthnCredential RPCs
- mciasdb: webauthn list/delete/reset subcommands
- OpenAPI: 6 new endpoints, WebAuthnCredentialInfo schema
- Policy: self-service enrollment rule, admin remove via wildcard
- Tests: DB CRUD, adapter round-trip, interface compliance
- Docs: ARCHITECTURE.md §22, PROJECT_PLAN.md Phase 14
Security: Credential IDs and public keys encrypted at rest with
AES-256-GCM via vault master key. Challenge ceremonies use 128-bit
nonces with 120s TTL in sync.Map. Sign counter validated on each
assertion to detect cloned authenticators. Password re-auth required
for registration (SEC-01 pattern). No credential material in API
responses or logs.

- Replace type: [string, "null"] array syntax with
type: string + nullable: true on AuditEvent.actor_id,
AuditEvent.target_id, PolicyRule.not_before, and
PolicyRule.expires_at; Swagger UI 5 cannot parse the
JSON Schema array form
- Add missing username field to /v1/token/validate response
schema (added to handler in d6cc827 but never synced)
- Add missing GET /v1/pgcreds endpoint to spec
- Sync web/static/openapi.yaml (served file) with root;
the static copy was many commits out of date, missing
all policy/tags schemas and endpoints

- New internal/vault package: thread-safe Vault struct with
seal/unseal state, key material zeroing, and key derivation
- REST: POST /v1/vault/unseal, POST /v1/vault/seal,
GET /v1/vault/status; health returns sealed status
- UI: /unseal page with passphrase form, redirect when sealed
- gRPC: sealedInterceptor rejects RPCs when sealed
- Middleware: RequireUnsealed blocks all routes except exempt
paths; RequireAuth reads pubkey from vault at request time
- Startup: server starts sealed when passphrase unavailable
- All servers share single *vault.Vault by pointer
- CSRF manager derives key lazily from vault
Security: Key material is zeroed on seal. Sealed middleware
runs before auth. Handlers fail closed if vault becomes sealed
mid-request. Unseal endpoint is rate-limited (3/s burst 5).
No CSRF on unseal page (no session to protect; chicken-and-egg
with master key). Passphrase never logged.

- REST handleTOTPEnroll now requires password field in request body
- gRPC EnrollTOTP updated with password field in proto message
- Both handlers check lockout status and record failures on bad password
- Updated Go, Python, and Rust client libraries to pass password
- Updated OpenAPI specs with new requestBody schema
- Added TestTOTPEnrollRequiresPassword with no-password, wrong-password,
and correct-password sub-tests
Security: TOTP enrollment now requires the current password to prevent
session-theft escalation to persistent account takeover. Lockout and
failure recording use the same Argon2id constant-time path as login.

- 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.
