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 stale "service" role option with correct set:
admin, user, guest, viewer, editor, commenter (matches model.go)
- Add Form/JSON tab toggle to policy create form
- JSON tab accepts raw RuleBody JSON with description/priority
- Handler detects rule_json field and parses/validates it
directly, falling back to field-by-field form mode otherwise
- Replace requireAdmin (role-based) guards on all REST endpoints
with RequirePolicy middleware backed by the existing policy engine;
built-in admin wildcard rule (-1) preserves existing admin behaviour
while operator rules can now grant targeted access to non-admin
accounts (e.g. a system account allowed to list accounts)
- Wire policy engine into Server: loaded from DB at startup,
reloaded after every policy-rule create/update/delete so changes
take effect immediately without a server restart
- Add service_account_delegates table (migration 000008) so a human
account can be delegated permission to issue tokens for a specific
system account without holding the admin role
- Add token-download nonce mechanism: a short-lived (5 min),
single-use random nonce is stored server-side after token issuance;
the browser downloads the token as a file via
GET /token/download/{nonce} (Content-Disposition: attachment)
instead of copying from a flash message
- Add /service-accounts UI page for non-admin delegates
- Add TestPolicyEnforcement and TestPolicyDenyRule integration tests
Security:
- Policy engine uses deny-wins, default-deny semantics; admin wildcard
is a compiled-in built-in and cannot be deleted via the API
- Token download nonces are 128-bit crypto/rand values, single-use,
and expire after 5 minutes; a background goroutine evicts stale entries
- alg header validation and Ed25519 signing unchanged

- 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.

- 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.

- Update package declaration in client.go
- Update error message strings to reference new package name
- Update test package and imports to use new name
- Update README.md documentation and examples with new package name
- All tests pass
- Add IsAdmin bool to PageData (embedded in all page view structs)
- Remove redundant IsAdmin from DashboardData
- Add isAdmin() helper to derive admin status from request claims
- Set IsAdmin in all page-level handlers that populate PageData
- Wrap admin-only nav links in base.html with {{if .IsAdmin}}
- Add tests: non-admin dashboard/profile hide admin links,
admin dashboard shows them
Security: navigation links to /accounts, /audit, /policies,
and /pgcreds are now only rendered for admin users. Server-side
authorization (requireAdminRole middleware) was already in place;
this change removes the information leak of showing links that
return 403 to non-admin users.

- Change dashboard route from adminGet to authed middleware
- Show account counts and audit events only for admin users
- Show welcome message for non-admin authenticated users
Security: non-admin users cannot access account lists or audit
events; admin-only data is gated by claims.HasRole("admin") in
the handler, not just at the route level.

- Trusted proxy config option for proxy-aware IP extraction
used by rate limiting and audit logs; validates proxy IP
before trusting X-Forwarded-For / X-Real-IP headers
- TOTP replay protection via counter-based validation to
reject reused codes within the same time step (±30s)
- RateLimit middleware updated to extract client IP from
proxy headers without IP spoofing risk
- New tests for ClientIP proxy logic (spoofed headers,
fallback) and extended rate-limit proxy coverage
- HTMX error banner script integrated into web UI base
- .gitignore updated for mciasdb build artifact
Security: resolves CRIT-01 (TOTP replay attack) and
DEF-03 (proxy-unaware rate limiting); gRPC TOTP
enrollment aligned with REST via StorePendingTOTP

- Web UI admin password reset now enforces admin role
server-side (was cookie-auth + CSRF only; any logged-in
user could previously reset any account's password)
- Added self-service password change UI at GET/PUT /profile:
current_password + new_password + confirm_password;
server-side equality check; lockout + Argon2id verification;
revokes all other sessions on success
- password_change_form.html fragment and profile.html page
- Nav bar actor name now links to /profile
- policy: ActionChangePassword + default rule -7 allowing
human accounts to change their own password
- openapi.yaml: built-in rules count updated to -7
Migration recovery:
- mciasdb schema force --version N: new subcommand to clear
dirty migration state without running SQL (break-glass)
- schema subcommands bypass auto-migration on open so the
tool stays usable when the database is dirty
- Migrate(): shim no longer overrides schema_migrations
when it already has an entry; duplicate-column error on
the latest migration is force-cleaned and treated as
success (handles columns added outside the runner)
Security:
- Admin role is now validated in handleAdminResetPassword
before any DB access; non-admin receives 403
- handleSelfChangePassword follows identical lockout +
constant-time Argon2id path as the REST self-service
handler; current password required to prevent
token-theft account takeover

- 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).
- internal/ui/ui.go: add PGCred, Tags to AccountDetailData; register
PUT /accounts/{id}/pgcreds and PUT /accounts/{id}/tags routes; add
pgcreds_form.html and tags_editor.html to shared template set; remove
unused AccountTagsData; fix fieldalignment on PolicyRuleView, PoliciesData
- internal/ui/handlers_accounts.go: add handleSetPGCreds — encrypts
password via crypto.SealAESGCM, writes audit EventPGCredUpdated, renders
pgcreds_form fragment; password never echoed; load PG creds and tags in
handleAccountDetail
- internal/ui/handlers_policy.go: fix handleSetAccountTags to render with
AccountDetailData instead of removed AccountTagsData
- internal/ui/ui_test.go: add 5 PG credential UI tests
- web/templates/fragments/pgcreds_form.html: new fragment — metadata display
+ set/replace form; system accounts only; password write-only
- web/templates/fragments/tags_editor.html: new fragment — textarea editor
with HTMX PUT for atomic tag replacement
- web/templates/fragments/policy_form.html: rewrite to use structured fields
matching handleCreatePolicyRule (roles/account_types/actions multi-select,
resource_type, subject_uuid, service_names, required_tags, checkbox)
- web/templates/policies.html: new policies management page
- web/templates/fragments/policy_row.html: new HTMX table row with toggle
and delete
- web/templates/account_detail.html: add Tags card and PG Credentials card
- web/templates/base.html: add Policies nav link
- internal/server/server.go: remove ~220 lines of duplicate tag/policy
handler code (real implementations are in handlers_policy.go)
- internal/policy/engine_wrapper.go: fix corrupted source; use errors.New
- internal/db/policy_test.go: use model.AccountTypeHuman constant
- cmd/mciasctl/main.go: add nolint:gosec to int(os.Stdin.Fd()) calls
- gofmt/goimports: db/policy_test.go, policy/defaults.go,
policy/engine_test.go, ui/ui.go, cmd/mciasctl/main.go
- fieldalignment: model.PolicyRuleRecord, policy.Engine, policy.Rule,
policy.RuleBody, ui.PolicyRuleView
Security: PG password encrypted AES-256-GCM with fresh random nonce before
storage; plaintext never logged or returned in any response; audit event
written on every credential write.
- 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.
- 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.
- Introduced `web/templates/` for HTMX-fragmented pages (`dashboard`, `accounts`, `account_detail`, `error_fragment`, etc.).
- Implemented UI routes for account CRUD, audit log display, and login/logout with CSRF protection.
- Added `internal/ui/` package for handlers, CSRF manager, session validation, and token issuance.
- Updated documentation to include new UI features and templates directory structure.
- Security: Double-submit CSRF cookies, constant-time HMAC validation, login password/Argon2id re-verification at all steps to prevent bypass.
- 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.
