Bohan Jiang 13f74e651a feat(agents): remove custom_env from agent resources, add audited env endpoint (MUL-2600) (#3209)
* 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`.

Multica Mobile (iOS)

Expo + React Native iOS client for Multica. Independent from web/desktop — shares only types from @multica/core/. See CLAUDE.md for the locked tech-stack baseline and import rules.

Just want to use it on your phone? (no development)

Multica isn't on the App Store yet — until that changes, anyone who wants it on their iPhone builds from source. One command:

pnpm ios:mobile:device:prod:release

This connects to the same backend as multica.ai, so your existing account just works.

Prerequisites: Mac with Xcode, a free Apple ID added under Xcode → Settings → Accounts, iPhone connected via USB with Developer Mode enabled. Walk through Expo's Set up your environment (pick Development build → iOS Device) if any of that is missing.

Xcode signs the build with the "Personal Team" your Apple ID automatically owns — created silently the first time you signed into Xcode, no setup needed. The first build downloads CocoaPods + compiles React Native from source — expect 1020 minutes. Subsequent builds reuse Xcode's cache.

If Xcode rejects signing with "No matching provisioning profiles found" — rare, happens if someone has claimed the default bundle id ai.multica.mobile on Apple's developer portal. Pick any reverse-domain you own and re-run:

export EXPO_BUNDLE_IDENTIFIER_PROD=com.yourname.multica
pnpm ios:mobile:device:prod:release

7-day signing limit: a free Apple ID signs builds for 7 days. After that, plug back into the Mac and re-run the command to re-sign. An Apple Developer Program account ($99/yr) extends this to 1 year.

Everything below is for app developers — you can ignore the rest if you only wanted a personal install.

Scripts

Command What it does Backend
pnpm dev:mobile Metro only (reuse existing install) local (.env.development.local)
pnpm dev:mobile:staging Metro only (reuse existing install) staging (.env.staging)
pnpm dev:mobile:prod Metro only (reuse existing install) production (.env.production)
pnpm ios:mobile Full rebuild + install on iOS Simulator, Debug local
pnpm ios:mobile:staging Full rebuild + install on iOS Simulator, Debug staging
pnpm ios:mobile:prod Full rebuild + install on iOS Simulator, Debug production
pnpm ios:mobile:device Full rebuild + install on USB iPhone, Debug local
pnpm ios:mobile:device:staging Full rebuild + install on USB iPhone, Debug staging
pnpm ios:mobile:device:staging:release Full rebuild + install on USB iPhone, Release (standalone) staging
pnpm ios:mobile:device:prod Full rebuild + install on USB iPhone, Debug production
pnpm ios:mobile:device:prod:release Full rebuild + install on USB iPhone, Release (standalone) production

dev:* runs Metro only — assumes the matching variant is already installed. ios:mobile* does a full native rebuild + install.

Bundle id and display name switch on APP_ENV (see app.config.ts), so Dev / Staging / Production variants can coexist on the same device or simulator.

First-time setup

.env.staging is committed (public staging URL). .env.development.local is gitignored — copy the template once:

cp apps/mobile/.env.example apps/mobile/.env.development.local
# then edit EXPO_PUBLIC_API_URL inside it to your Mac's LAN IP, e.g. http://192.168.1.42:8080

If your Apple ID isn't on the Multica Apple Developer team yet, also uncomment and set EXPO_BUNDLE_IDENTIFIER_DEV to a reverse-domain you own (e.g. com.yourname.multica.dev). This only overrides the dev variant — staging / production bundle ids are intentionally not overridable so variants can coexist.

Build it onto your iPhone

Two paths, depending on what you want to do:

Day-to-day development (Mac in front of you)

pnpm ios:mobile:device:staging

Produces a Debug build with expo-dev-launcher embedded. Every launch the app probes Metro on your Mac and pulls fresh JS — perfect for hot-reload, painful when the Mac is asleep or you're on a different WiFi.

Standalone / "just use it" (walk away from the Mac)

pnpm ios:mobile:device:staging:release

Produces a Release build. No expo-dev-launcher, no Metro probe, no "Downloading…" screen. Splash → app, exactly like an App Store install. Trade-off: every JS change requires re-running this command.

Both paths share the same prerequisites: Mac with Xcode, free Apple ID added under Xcode → Settings → Accounts, iPhone connected via USB with Developer Mode enabled. Follow Expo's Set up your environment — pick Development build → iOS Device — if any of that is missing.

First build of either variant downloads CocoaPods + compiles React Native from source — expect 10-20 minutes. Subsequent builds reuse Xcode's DerivedData cache.

Try it in the iOS Simulator (no iPhone needed)

pnpm ios:mobile:staging

Boots the simulator, builds, installs the dev-client. Faster to iterate than a device build because no signing / provisioning step. Same dev:mobile:staging Metro flow afterward.

7-day signing limit (device only)

A free Apple ID signs builds for 7 days only, Debug and Release both. After that the app refuses to launch on the iPhone. Plug back into the Mac and re-run the corresponding ios:mobile:device* script to re-sign. Simulator builds are unaffected. The only workaround for the device limit is an Apple Developer Program account ($99/yr), which extends to 1 year.

Pointing at a different backend

Edit EXPO_PUBLIC_API_URL in .env.staging, .env.production, or .env.development.local (whichever variant you're running). Then:

  • For an installed Debug build: restart Metro (pnpm dev:mobile:staging) so the next JS bundle picks up the new value.
  • For an installed Release build: re-run the ios:mobile:device:staging:release command — the value is baked into the embedded bundle at build time.

For local backend testing, use your Mac's LAN IP (ipconfig getifaddr en0), not localhost.
