* feat(auth): support mcn_ Cloud Node PATs verified via Fleet
Adds a new token kind, mcn_ (multica cloud node), recognized in both
the regular Auth and DaemonAuth middlewares. mcn_ tokens are minted
and owned by Multica Cloud (not the local personal_access_tokens
table); the server validates them by POSTing to the Fleet's
/api/v1/pat/verify endpoint and uses the returned owner_id as
X-User-ID for downstream handlers.
Cloud is the authoritative owner of token status, so this is a
verifier-only path with no DB fallback:
* Fleet says valid:false -> 401 (token genuinely bad)
* Fleet unreachable / 5xx -> 503 (transient, retry)
* No MULTICA_CLOUD_FLEET_URL configured -> 401 (fail closed)
Verification results are cached in Redis for 60s under
mul:auth:mcn:<sha256> to bound the per-request load on Fleet without
extending the revocation window beyond what the Cloud doc allows.
Negative results are NOT cached, so a freshly minted token doesn't
get locked out by a stale 'token_not_found'.
Reuses MULTICA_CLOUD_FLEET_URL (the same env the cloud-runtime proxy
already uses) so deployments don't need a second config knob.
Tests cover the happy path, every documented invalid reason, 4xx/5xx
mapping, network error, decode error, ctx cancellation, the
fail-closed valid:true-without-owner_id case, trailing-slash URL
normalization, and the Redis cache short-circuit + negative
no-cache contract. Middleware tests pin the four 401/503/200 outcomes
in both Auth and DaemonAuth.
* auth(mcn): require owner_id to map to a real local user; drop X-User-PAT plumbing
Two related changes:
1. Cloud-verified owner_id is now checked against our local users table.
The Cloud owner_id and our users.id share the same UUID space by
contract; a missing local user means either the row was deleted
under an active node or something is forging owner_ids — either
way, fail closed.
CloudPATVerifier.Verify takes a new OwnerLookupFunc:
- returns (true, nil) -> success, cache + return
- returns (false, nil) -> ErrCloudPATInvalid (reason='owner_unknown'),
NOT cached (so a freshly-created user
doesn't get locked out for a TTL window)
- returns (_, error) -> ErrCloudPATUnavailable (transient,
middleware emits 503)
Both Auth and DaemonAuth wire ownerLookupFor(queries), a new shared
helper that wraps queries.GetUser, mapping pgx.ErrNoRows / unparseable
UUIDs to (false, nil) and other errors to a real Go error.
2. Removed all X-User-PAT plumbing. Cloud now mints node-scoped mcn_
PATs itself during /api/v1/nodes (see multica-cloud
docs/api/node-pat.md) and ships them into the EC2 instance via SSM,
so multica-api no longer needs to forward the caller's mul_ PAT.
Propagating a long-lived user PAT into a remote machine widened
the blast radius of any node compromise; that's gone now.
Removed:
- cloud_runtime.go: withUserPAT option, cloudRuntimeUserPAT,
generateCloudRuntimePAT, revokeGeneratedPAT
- cloudruntime/Request.UserPAT field + X-User-PAT header
- X-User-PAT from CORS allowed headers
- obsolete handler tests:
TestCreateCloudRuntimeNodeForwardsValidatedPAT
TestCreateCloudRuntimeNodeRejectsUnownedPAT
TestCreateCloudRuntimeNodeRejectsExpiredPAT
TestCreateCloudRuntimeNodeAutoGeneratesPAT
replaced with TestCreateCloudRuntimeNodeForwardsBody
- X-User-PAT references in packages/core/api/client.test.ts
Tests:
* 3 new verifier-level tests (owner_unknown not cached, lookup error
-> Unavailable, success path is cached for both fleet AND lookup)
* 5 new owner_lookup_test.go tests (nil queries, existing user,
missing user, malformed UUID, DB error)
* 1 new end-to-end DaemonAuth test (cloud says valid, no local user
-> 401)
* Existing X-User-PAT TS assertions removed; full vitest run passes.
* go test ./... and go vet ./... clean on the server module.
* feat(agents): remove custom_env from agent resources, add audited env endpoint (MUL-2600)
The agent resource shape (list / get / create / update / archive /
restore responses + WebSocket events) no longer carries `custom_env`
values. Reads/writes of env now flow exclusively through a dedicated
`/api/agents/{id}/env` endpoint that is owner/admin-only, rejects
agent-actor sessions, applies a "****" sentinel preserve guard on
PUT, and writes a persistent audit row per reveal/update.
Why
- `multica agent list --output json` historically returned plaintext
`custom_env` for owner/admin callers (the redaction gate gave only
members the masked map). Any agent token running on the workspace
inherits its owner's role and could read every other agent's
secrets just by listing.
- Patching list/get redaction alone (PR #3175 direction) left
symmetric leaks via mutation responses, WS events, the "reveal"
path itself (no actor-aware auth), and a `****` overwrite footgun
on UpdateAgent.
What changed
- Backend: drop `custom_env` from AgentResponse; add coarse
`has_custom_env` + `custom_env_key_count`. Strip env handling from
UpdateAgent (silently ignored if sent). Keep CreateAgent's
custom_env acceptance.
- Backend: new GET/PUT `/api/agents/{id}/env` handlers in
`internal/handler/agent_env.go`:
- resolveActor → 403 for agent actors (closes the lateral-movement
path).
- Owner/admin role gate via existing helper.
- PUT honours value == "****" as "preserve existing value".
- Both write to `activity_log` with `agent_env_revealed` /
`agent_env_updated` actions. Audit details record key names only,
never values.
- Daemon claim path (`ClaimAgentTask`) unchanged — `TaskAgentData`
still carries plaintext env for runtime injection.
- SQL: new `UpdateAgentCustomEnv` query; sqlc regenerated (v1.31.1).
- CLI: new `multica agent env get|set` subcommands. `--custom-env*`
flags removed from `multica agent update`; the no-fields error
now points to the new path.
- Frontend: drop env fields from `Agent` + `UpdateAgentRequest`; add
`getAgentEnv` / `updateAgentEnv` client methods; rewrite env-tab
to show "N variables configured" + explicit "Reveal & edit"
button, fetching values only on intentional reveal.
- Locales: parity-safe additions to en + zh-Hans.
- Docs: agents-create.{mdx,zh.mdx} reflect the new threat model and
endpoint.
- Mobile: schema drops `custom_env` / `custom_env_redacted`, adds
metadata fields.
Tests
- Handler tests pinned the new invariants: no env in list/get
responses, owner reveal happy-path + audit row, agent-actor 403,
`****` sentinel preserves real values, UpdateAgent silently
ignores `custom_env`, pure `mergeAgentEnv` cases.
- CLI tests pivot to the new flag surface: `agent update` MUST NOT
expose the env flags; `agent env set` MUST expose
--custom-env-stdin/--custom-env-file.
- Frontend test fixtures updated; pnpm typecheck / test / lint
pass cleanly.
This is a breaking API change. Scripts that read `custom_env` from
`/api/agents` must migrate to `GET /api/agents/{id}/env`.

* fix(agents): close actor-spoofing + audit fail-closed in env endpoints (MUL-2600)
Addresses Elon's review of #3209:
* Mint a task-scoped `mat_` token per claim, bound to (agent, task,
workspace, owner). Daemon injects it into the agent process in place
of its own credential. Auth middleware authoritatively rebuilds
X-User-ID / X-Agent-ID / X-Task-ID from the token row and sets
X-Actor-Source=task_token; that header is server-set only — incoming
values are stripped before any auth branch runs. resolveActor honors
the header so an agent that strips X-Agent-ID / X-Task-ID still
resolves as actor=agent.
* GetAgentEnv / UpdateAgentEnv are now fail-closed on audit-log
failures: GET refuses to return plaintext, PUT persists inside the
same tx as the audit row so they commit/roll back together.
* PUT /api/agents/{id} returns 400 when the body carries custom_env
instead of silently dropping it — directs callers to the audited env
endpoint.
* Agent actors never see mcp_config, even when the underlying member
is owner/admin; mutation broadcasts go through a redaction shim so
WS subscribers don't pick it up either.
* Fix backend test that asserted dense JSON (jsonb::text renders
whitespace) and frontend test that assumed a unique "Test User"
match.

* fix(agents): close residual MUL-2600 gaps from review (MUL-2600)
Migration 108 FK now correctly references agent_task_queue(id) instead
of the non-existent agent_task table; the previous name blocked CI
backend migrations.
Task-token-authenticated requests can no longer be re-routed at a
different workspace by passing workspace_slug / workspace_id /
?workspace_id / a URL workspace param. ResolveWorkspaceIDFromRequest
and resolveWorkspaceUUID both short-circuit on X-Actor-Source=task_token
and return only the token-bound X-Workspace-ID; buildMiddleware adds a
defence-in-depth 403 if any URL-resolved workspace disagrees with the
token binding.
mcp_config no longer leaks back to agent actors through UpdateAgent /
CreateAgent / ArchiveAgent / RestoreAgent HTTP responses — the same
redactAgentResponseForActor helper that GetAgent/ListAgents use is now
applied to mutation responses too. WS broadcasts were already redacted
via broadcastAgentResponse.
FailTask and every TaskService cancel path (CancelTask /
CancelTasksForIssue / CancelTasksForAgent / CancelTasksByTriggerComment
/ BroadcastCancelledTasks) now eagerly DeleteTaskTokensByTask so the
mat_ token's 24h window doesn't outlive a terminated task. Failure is
non-fatal — the FK cascade and expiry remain durable guards.
Doc-only: clarify that PUT /api/agents/{id} now hard-rejects bodies
that carry custom_env (was previously "silently ignores").
Tests:
- middleware: TestResolveWorkspaceIDFromRequest gains a task_token
case asserting client-supplied slug/id/query cannot override the
bound workspace.
- handler: TestUpdateAgent_RedactsMcpConfigForAgentActor and
TestUpdateAgent_KeepsMcpConfigForMemberActor pin the mutation-
response redaction contract per actor type.

* fix(agents): match redacted mcp_config as JSON null, not Go nil (MUL-2600)
`AgentResponse.McpConfig` is `json.RawMessage` without `omitempty`, so
the redacted response serialises as `"mcp_config": null`. On decode,
`json.RawMessage` keeps the literal bytes `null` rather than collapsing
to Go nil, which made the assertion fire on a non-leak.
The product contract (field always present, distinguished from "no
config" via `mcp_config_redacted`) is intentional, so adjust the test
to check for "no secret-bearing content" instead of weakening the
contract via `omitempty`.

* feat(auth): make auth token TTL configurable via AUTH_TOKEN_TTL env var
Add AUTH_TOKEN_TTL environment variable (in seconds) to override the
hardcoded 30-day auth token lifetime. Self-hosted deployments on trusted
networks can set a longer value to avoid frequent magic-link
re-authentication.
The value is read once at startup and cached. Invalid or missing values
fall back to the 30-day default with a warning log.
Closes#2685

- Warn on unreasonable values (>10 years) but still accept them

* fix: use AuthTokenTTL() in CloudFront middleware, guard ParseInt overflow
Address review feedback from Bohan-J (round 2):
1. CloudFront refresh middleware (cloudfront.go:21) was hardcoding
30*24*time.Hour instead of using auth.AuthTokenTTL(). Now calls
AuthTokenTTL() so the middleware respects AUTH_TOKEN_TTL env var.
2. parseAuthTokenTTL integer-seconds branch: very large values like
9999999999 would silently overflow int64 when multiplied by
time.Second. Added overflow guard comparing against
math.MaxInt64/int64(time.Second) before the multiplication.
3. Updated AuthTokenTTL() doc comment to reflect that it accepts
Go duration strings or integer seconds (not just seconds).
4. Added middleware test (cloudfront_test.go) verifying short
AUTH_TOKEN_TTL produces short cookie expiry, not 30-day hardcode.
Also covers nil signer and existing-cookie-skip cases.
5. Added integer overflow test case to cookie_test.go.

* feat(auth): cache workspace membership for daemon heartbeat path
Cache workspace membership existence (not role) in Redis to eliminate a
DB round-trip on every PAT-authenticated daemon heartbeat. Follows the
existing PATCache nil-safe pattern.
Key design decisions per reviewer feedback:
- Cache existence only (sentinel "1"), not role string. Authorization
decisions that depend on role always hit the DB directly. This
eliminates the cache-aside race where a stale elevated role could
persist after a downgrade.
- Proactive invalidation on UpdateMember, DeleteMember, LeaveWorkspace,
and DeleteWorkspace (iterates members before cascade delete).
- 5 min TTL. Combined with PATCache (10 min), worst-case revocation
delay is max(10m, 5m) = 10 min — consistent with original PATCache
design decision.
Limitations:
- Non-members still hit DB on every request (negative caching not
implemented — the scenario is rare for daemon endpoints which require
valid workspace-scoped tokens).

* test(auth): drive membership cache invalidation through real handlers
- TestRequireDaemonWorkspaceAccess_CacheHit now uses a ghost user with no
member row, so the only path to a granted access is the cache short-circuit.
Without priming the cache the access check must fail; with priming it must
succeed. A future change that bypasses the cache would fail the second
assertion.
- Replaces the cache-only InvalidatedOnMemberRemoval test (which only
re-exercised the auth-package primitive) with four handler-driven tests
that exercise DeleteMember, UpdateMember, LeaveWorkspace and
DeleteWorkspace via their real HTTP handlers. Each test prepares a real
member, primes the cache, calls the handler, and asserts the cache entry
is gone — so a refactor that drops one of the Invalidate(...) calls in
workspace.go will fail CI.

* feat(server/auth): cache PAT lookups in Redis with 60s TTL
Personal access tokens used to hit Postgres on every request: a SELECT
to resolve token_hash → user_id, plus a fire-and-forget UPDATE of
last_used_at. For a CLI / daemon making many requests per second this
is wasted DB load — the token is the same and the answer hasn't changed.
Add a Redis-backed cache (auth.PATCache) keyed by token hash, TTL 60s:
- On cache hit, the auth middleware skips both the SELECT and the
last_used_at UPDATE. last_used_at is now refreshed at most once per
TTL window per token, not per request.
- On cache miss the middleware falls back to today's behavior: query
Postgres, populate the cache, async-update last_used_at.
- On revoke, the handler invalidates the cache entry so revocation
takes effect immediately rather than waiting for the TTL to expire.
This required changing RevokePersonalAccessToken from :exec to :one
RETURNING token_hash.
The cache is nil-safe: when REDIS_URL isn't configured, NewPATCache
returns nil and the middleware degrades to today's always-hit-DB
behavior. JWT validation is untouched (already DB-free).
Tested with REDIS_TEST_URL — same gating pattern the rest of the
suite uses for Redis-backed tests. New tests cover nil-safety, set/
get/invalidate, TTL, and the middleware short-circuit on cache hit.
* fix(server/auth): clamp PAT cache TTL to token's remaining lifetime
GPT-Boy review caught: a PAT expiring in <60s would still be cached
for the full PATCacheTTL window, so the token could continue passing
auth on cache hit for up to ~60s after its expires_at. The DB query
filters expired tokens (revoked = FALSE AND expires_at > now()), but
that filter never ran on a cache hit.
Make Set take an explicit ttl, and add TTLForExpiry to compute it:
- no expires_at → full PATCacheTTL
- expires_at far → full PATCacheTTL
- expires_at <60s → time until expiry
- already expired → 0, Set skips caching (TOCTOU defense between
the SELECT and the Set, since the SELECT
already filters expired rows)
Regression test pins the clamp behavior end-to-end against Redis.
* feat(server/auth): cache daemon-token + PAT lookups in DaemonAuth, bump TTL to 10m
Daemon /api/daemon/* requests (heartbeat, claim task) hit DaemonAuth
which previously did its own GetDaemonTokenByHash on every request and
*also* duplicated the PAT lookup on the mul_ fallback — bypassing the
cache added in 1cdd674c. Today's daemons authenticate via mul_ PATs
(mdt_ minting isn't wired up yet), so the duplicate PAT path is the one
that actually matters for hot-path DB load.
Three changes:
1. New auth.DaemonTokenCache mirrors PATCache for the mdt_ path
(key = mul:auth:daemon:<sha256>, JSON value = {workspace_id, daemon_id}).
Forward-looking infrastructure for when daemon tokens get minted; the
middleware short-circuits the DB SELECT on cache hit. TTL clamped to
the token's expires_at via the shared TTLForExpiry helper.
2. DaemonAuth now also consults PATCache on its mul_ fallback, sharing
the same cache as the regular Auth middleware. A daemon making 4 hb/min
collapses from 4 GetPersonalAccessTokenByHash + 4 last_used_at writes
per minute to ~1 of each per AuthCacheTTL window (~10 minutes).
3. Rename PATCacheTTL → AuthCacheTTL and bump from 60s to 10 minutes.
The constant is now shared between PAT and daemon caches; 10m matches
the user-requested longer TTL for further DB write reduction. Revoke
latency on the happy path is still instant via active invalidation;
the worst-case (Redis Del miss / direct-DB revoke) grows from ~60s to
~10m.
Tests cover nil-safety, set/get/invalidate, TTL, clamped TTL on near-
expiry tokens, and the middleware short-circuit for both cache paths
(mdt_ via DaemonTokenCache, mul_ fallback via PATCache).
* feat(server/auth): cache PAT lookups on the WebSocket auth path
The third place a PAT is resolved — patResolver.ResolveToken used by
realtime.HandleWebSocket — was still hitting Postgres on every /ws
auth and firing an unconditional last_used_at UPDATE, bypassing the
cache added in 1cdd674c. Wire it through the same shared PATCache so
revoking a token through any path (Auth middleware, DaemonAuth PAT
fallback, or WS auth) hits all three caches with one Invalidate.
Also leaves a comment on DeleteDaemonTokensByWorkspaceAndDaemon —
the query has no caller today, but a future deregister/rotate flow
must remember to call DaemonTokenCache.Invalidate(hash) for each
deleted row, otherwise deleted daemon tokens stay valid until TTL.
The session cookie's Secure flag was tied to APP_ENV, and the
docker-compose self-host stack defaults APP_ENV to "production". On
plain-HTTP self-host deployments (LAN IP, private network) the browser
silently drops Secure cookies, leaving every subsequent /api/* call
anonymous and surfacing as 401 "auth: no token found" right after a
successful login.
Derive Secure from the scheme of FRONTEND_ORIGIN so HTTPS origins get
Secure cookies and plain-HTTP origins get non-secure cookies the
browser will actually store. Also harden cookieDomain() against the
other common trap: COOKIE_DOMAIN=<ip>, which RFC 6265 forbids and
browsers reject. Log a one-shot warning and fall back to host-only.
Docs: correct the COOKIE_DOMAIN description (it was labelled as
CloudFront-only but applies to session cookies too) and call out the
IP-literal pitfall in SELF_HOSTING_ADVANCED.md, self-hosting.mdx, and
.env.example.

* feat(auth): migrate auth token to HttpOnly cookie & implement WebSocket Origin whitelist
Security improvements from the MUL-566 audit report:
1. Auth token is now set as an HttpOnly, SameSite=Lax cookie on login,
preventing XSS-based token theft. Cookie-based auth includes CSRF
protection via double-submit cookie pattern. The Authorization header
path is preserved for Electron desktop app and CLI/PAT clients.
2. WebSocket upgrader now validates the Origin header against a
configurable allowlist (ALLOWED_ORIGINS env var), rejecting
connections from unauthorized origins.
Backend: new auth cookie helpers, middleware reads cookie as fallback,
WS handler accepts cookie auth, Origin whitelist, logout endpoint.
Frontend: CSRF token in API headers, cookie-aware auth store and WS
client, web app opts into cookieAuth mode while desktop keeps tokens.
