MCIAS now acts as an SSO provider for downstream services. Services
redirect users to /sso/authorize, MCIAS handles login (password, TOTP,
or passkey), then redirects back with an authorization code that the
service exchanges for a JWT via POST /v1/sso/token.
- Add SSO client registry to config (client_id, redirect_uri,
service_name, tags) with validation
- Add internal/sso package: authorization code and session stores
using sync.Map with TTL, single-use LoadAndDelete, cleanup goroutines
- Add GET /sso/authorize endpoint (validates client, creates session,
redirects to /login?sso=<nonce>)
- Add POST /v1/sso/token endpoint (exchanges code for JWT with policy
evaluation using client's service_name/tags from config)
- Thread SSO nonce through password→TOTP and WebAuthn login flows
- Update login.html, totp_step.html, and webauthn.js for SSO nonce
passthrough
Security:
- Authorization codes are 256-bit random, single-use, 60-second TTL
- redirect_uri validated as exact match against registered config
- Policy context comes from MCIAS config, not the calling service
- SSO sessions are server-side only; nonce is the sole client-visible value
- WebAuthn SSO returns redirect URL as JSON (not HTTP redirect) for JS compat

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.

- Add id="login-card" to the .card wrapper div
- Change hx-target to #login-card (was #login-form)
- Add hx-select="#login-card" so htmx extracts only
the card element from the full-page response
Without hx-select, htmx replaced the form's outerHTML
with the entire page response, inserting a new .card
inside the existing .card on every failed attempt.

- 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.
- 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.
