Slice 1 + 3 of the user-management feature from the May 12 plan.
Backend-only - no UI yet (slice 2 ships separately). Backend +
accept-handler together so the email accept link is functional
from day one without a half-state.
Endpoints added:
- GET /api/workspaces/:id/members (any member; via_org=true
for org-level entries,
read-only from ws context)
- GET /api/workspaces/:id/invites (workspace_admin)
- POST /api/workspaces/:id/invites (workspace_admin)
- DELETE /api/workspaces/:id/invites/:inviteId (workspace_admin)
- PUT /api/workspaces/:id/members/:userId (workspace_admin)
- DELETE /api/workspaces/:id/members/:userId (workspace_admin)
- POST /api/auth/accept-invite/:inviteId (requireAuth +
case-insensitive
email match)
Permission gating:
- canAdminWorkspace (existing) for admin-gated endpoints
- canAccessWorkspace (new helper in lib/permissions.js) for the
members read endpoint - mirrors canAdminWorkspace shape but
admits any workspace_members role plus org/platform paths
Security additions vs the original plan:
- Transaction-bounded collision check on POST /invites closes the
TOCTOU race between simultaneous duplicate POSTs (no UNIQUE
constraint on workspace_invites(workspace_id, email))
- Per-(inviter, workspace), hour-window rate limit on POST /invites
to prevent abuse / cost runaway. Env-configurable via
INVITE_RATE_LIMIT_PER_HOUR with conservative 50/hour default.
429 response is generic - does not echo the configured value.
- Invite expiry env-configurable via INVITE_EXPIRY_DAYS (default 7)
- PUBLIC_URL env var (optional) pins the accept-URL origin in prod;
falls back to request-derived for local dev
Rollback rule on email send: only graph_error (real send attempt
failed at Graph) deletes the row and returns 502. not_configured
and dev_restricted are intentional non-sends - keep the row, count
against rate limit, allow local accept-invite testing to proceed.
Other safety blocks:
- Cannot demote/remove the last workspace_admin (409)
- Cannot remove the parent-org's org_owner via workspace path (403)
- Accept-invite is idempotent if user already a member
- Expired invites delete-on-read and return 410
- Wrong-account accept returns 403 without touching the invite
Expired-invite cleanup added to services/heartbeat.js mirroring
the team_invites sweep pattern.
Verification: 9-case curl-driven E2E against the dev DB fixture
(switcher-test + invitee-existing + invitee-new mid-flow register).
All 9 pass: create / collision-409 / second-create / rate-limit-429 /
existing-user-accept / register-then-accept / wrong-account-403 /
expired-410 / viewer-cannot-invite-403.

Fix: at connect, enumerate the user's accessible workspace_ids (direct workspace_members + org_owner/admin paths + platform_admin 'all') via new accessibleWorkspaceIds() helper in lib/tenancy.js; socket.join one room per workspace. All 12 dashboardNs.emit sites across deviceSocket / heartbeat / server.js / devices route / video-walls route now route via dashboardNs.to(workspaceRoom(...)).emit() with the workspace looked up from the relevant device or wall. New lib/socket-rooms.js holds the helpers and breaks a circular dependency (dashboardSocket already requires heartbeat, so heartbeat can't require dashboardSocket).
Inbound 6 commands rewired to canActOnDevice(socket, deviceId, tier): request-screenshot is read tier (workspace_viewer+); remote-touch/key/start/stop and device-command are write tier (workspace_editor+). Platform_admin and org_owner/admin always pass via actingAs. Legacy admin/superadmin branch dropped.
Lifecycle note: workspace-switch already calls window.location.reload (Phase 3 switcher), which forces a fresh socket with updated memberships - no per-emit re-evaluation needed.
Smoke tested with 3 simultaneous socket.io-client connections (switcher-test, swninja, dw5304 platform_admin) + direct canActOnDevice invocation for 6 user/device/tier combinations. All 9 outbound isolation cells and all 6 permission gates pass. Fixture mutation: switcher-test's Field Crew membership flipped from workspace_editor to workspace_viewer to exercise the read/write tier split in one login.
