Threads per-user ownership through sessions, cases, cron, and the permission
policy. All scoping is a no-op in single-user mode (isMultiUserMode() guards).
Sessions
- Session.owner stamped at every create path from req.authUser / job.owner:
POST /api/sessions, /api/run, /api/quick-start, ralph start, cron launch,
plan generation. Round-trips through recovery (MuxSession.owner mirror, read
muxSession.owner ?? savedState?.owner) and the mux layer.
- findSessionOrFail(ctx, id, req) now does a NOT_FOUND owner check (never 403, so
other users' session existence is not leaked); wired at ~50 call sites.
- List endpoints filtered by owner: GET /api/sessions, /api/sessions/unified
(live+persisted+lifecycle scoped, host-wide transcripts admin-only), cron jobs.
Permission policy (section 6.3)
- resolveClaudeModeForUsername wraps getClaudeModeConfig at every spawn site so a
non-granted user is forced to --permission-mode auto (bypass -> auto), including
recovery (or a reboot would un-downgrade). buildPromptArgs now respects the
session's claudeMode, closing the one-shot (runPrompt) bypass hole.
- Shell mode and cron launchCommand require canBypassPermissions: 403 at
POST /api/sessions, /api/quick-start create, cron job create, AND cron fire time
(re-checked against the owner's current grant).
Cases
- resolveCasesDir(user): per-user ~/codeman-users/<name>/cases in multi-user, the
shared ~/codeman-cases otherwise. All case CRUD + ralph + plan + quick-start
resolve through it. resolveCasePath is owner-aware.
- GET /api/cases scoped per user (own folders; legacy linked cases admin-only;
remote/docker cases owner-filtered). RemoteCase/DockerCase gain owner, stamped
at link/quickcreate/import.
- Remote + Docker host CRUD is admin-only.
- Non-admin workingDir confinement (the linchpin): realpath must resolve inside the
user's space, enforced at POST /api/sessions and /api/run BEFORE any disk write.
Limits
- sessionCapacityState / sessionCapacityMessage centralize the global + per-user
cap (CODEMAN_MAX_SESSIONS_PER_USER, default global/2), replacing the 6 copy-pasted
MAX_CONCURRENT_SESSIONS checks.
Tests: test/ownership-scoping.test.ts (case isolation, host-CRUD gate, workingDir +
shell gates, and the scoping helpers). Deferred to phase 4: WS owner gate, SSE
fan-out filtering, file-route preview/thumbnail helper scoping, push routing.
