The opt-in multi-user feature's only enforcement is web-layer scoping
(all sessions share one OS account). An adversarial review found 8 critical
+ 7 high cross-user holes that defeated it, plus mediums; all fixed here.
Single-user (flag-off) behavior stays byte-identical apart from documented
consistency deltas.
Ownership / confinement:
- DELETE /api/sessions (bulk) + /:id now owner-scope / findSessionOrFail
- quick-start, cron (create+fire), scheduled runs confine workingDir to the
owner's space; case link/docker-link/docker-import confine the host path
- resolveCasePath no longer resolves linked cases for non-admins; foreign
remote/docker cases are skipped (fall through to the caller's own local case)
- history, subagents/workflows, mux-sessions, orchestrator, cron run-history,
away-digest, and remote/docker host reads are owner- or admin-scoped
Permission policy (section 6.3):
- non-granted users are downgraded at every spawn site incl. legacy
/api/scheduled, PlanOrchestrator one-shots, remote launch, and the cron-fire
gemini/codex bypass switches; resolveClaudeModeForUsername now fails closed
Auth / store:
- verify-first login throttle (a correct password is never locked out),
/ws terminal subject to the change-password lockbox, cookie fast-path
re-validates identity live, role/grant changes revoke sessions, admin delete
runs the last-admin guard before any teardown
- users.json: distinguish missing (ENOENT) from corrupt/unreadable so a bad
read can't overwrite all accounts; unique per-process temp write path
Event streams:
- debounced session:updated + batched task:updated, clipboard, and push
notifications route by owner (fail closed); getLightState hides machine-wide
globalStats from non-admins
Tests: two suites updated to assert the fixed (secure) behavior. tsc, eslint,
and test:ci all green.

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.

- Breaker reset is now explicit-only: POST /api/sessions/:id/interactive no
longer unconditionally resets the PTY-exit breaker (that endpoint IS the
frontend's automatic re-attach path, so the breaker could never trip on the
COD-115 crash loop and any tab click silently re-armed it). The route accepts
a schema-validated optional body flag {clearBreaker:true}
(InteractiveStartSchema) and resets only when it is sent.
- Frontend restart control: app.js selectSession keeps the bare auto-attach
(no body, never clears); when the selected session has respawnBlocked it asks
for explicit user confirmation and only then re-POSTs with clearBreaker:true.
respawnBlocked is surfaced via SessionState/toState() (runtime-only, not
restored on boot so recovery can re-attach).
- Trip observability: WebServer.setupSessionListeners() is now idempotent
(skips while refs are attached) and the re-attach routes (/interactive,
/interactive-respawn, /shell) re-run it, restoring the wiring that the exit
handler detaches on every PTY exit — without this the 5th-exit trip had
guaranteed zero listeners (no SSE, no push, no persist, no run-summary).
- Push notification: added SessionRespawnBreakerTripped to PUSH_EVENT_MAP
('Session crash loop stopped', urgency critical) with an exit-count body
branch; previously sendPushNotifications silently no-oped.
- Minor: buildMuxAttachEnv() truecolor param is now actually passed
(codex/gemini, mirrors buildEnvExports); buildClaudeEnv() uses delete for
COLORTERM/CLAUDECODE (same node-pty "KEY=undefined" quirk as COD-115).
- Tests: route tests assert auto-reattach does NOT reset, clearBreaker resets,
invalid flag rejected, and listener re-wiring on /interactive + /shell;
real-wiring lifecycle tests (createSessionListeners/attach/detach) prove the
exit-detach gap and that re-setup keeps the 5th-exit trip observable;
PUSH_EVENT_MAP regression guard.

Blocker: runCodex read raw response shapes, but the global
preSerialization hook (server.ts) wraps every payload in the
{ success, data } envelope — status.available was always undefined, so
the UI unconditionally printed "Codex CLI not found" and could never
start a session; the created session was also never auto-selected
(data.sessionId vs data.data.sessionId). Fixed both reads to match
runOpenCode, and updated the test mocks to the real wire shape (plus a
selectSession assertion) so envelope drift fails the test.
Guard parity: export isExternalCliMode() from session.ts and use it in
the ralph-config guard, all three respawn guards, and the six restore/
setup guards in server.ts that previously only excluded 'opencode' —
codex sessions could otherwise get a Ralph tracker or respawn
controller attached (idle detection is Claude-specific and output-
silence respawn cycling would misfire on a quiet codex TUI).
UI parity: cx tab badge, "Kill Tmux & Codex" dialog title, and the
missing CSS (.run-mode-dot.codex, .tab-mode.codex, .mode-codex button
colors — purple) so the Codex menu dot is no longer invisible. Removed
the dead object-literal runMode getter that Object.assign flattens
(superseded by the defineProperty accessor this PR adds).
Verified end-to-end on an isolated instance with a stub codex binary:
10/10 Playwright checks (menu/dot/label/button styling, session
created + auto-selected, cx badge, TUI output streamed, ralph+respawn
guards reject codex) and --dangerously-bypass-approvals-and-sandbox
+ --model observed on the spawned command line.

Point 1 of the v1.0 lock-in: commit to a stable HTTP API (the cleanest, fullest form).
Core (centralized):
- Every JSON /api response now uses ONE envelope via a Fastify preSerialization hook (src/web/server.ts): success -> { success:true, data:<payload> }; error -> { success:false, error, errorCode } with a conventional HTTP status. Non-JSON routes (file-raw, tail-file SSE, download, screenshots, /q redirect, WS) are skipped.
- Error-code -> HTTP status is a single source of truth (httpStatusForErrorCode in src/types/api.ts): 400/401/404/409/422/429/500. Expanded ApiErrorCode (added UNAUTHORIZED, CONFLICT, RATE_LIMITED). Errors are no longer HTTP 200.
- Versioned alias: /api/v1/* rewrites to /api/* (rewriteApiV1Url), so external clients pin to a stable surface while the bundled UI keeps using /api/*.
- Handlers stripped of manual 'success:true' (50 across 14 route files) so they return bare payloads the hook wraps uniformly; fixed the mux DELETE {success:<bool>} envelope collision (-> {killed}).
Frontend (48 call sites across 10 files):
- _apiJson() auto-unwraps { success:true, data } -> data (null on error), so most bare-shape readers are transparent. Raw-fetch sites relocate payload reads under .data; success/res.ok/error checks unchanged.
Docs: new docs/api-reference.md (envelope, status table, error codes, /api/v1, SSE); versioning-policy.md flipped — the HTTP/SSE API is now part of the stable, SemVer-covered surface.
Verification: full unit/route suite green (2680 passed) incl. ~166 updated assertions across 24 test files; typecheck/lint/format/frontend-syntax clean; a headless-chromium smoke loaded the migrated UI and drove the panels with 0 console/page errors; /api/status and /api/v1/status confirmed returning the uniform envelope live.

Green pulsing dot in the desktop header shows when Cloudflare tunnel is active.
Clicking opens a dropdown panel with tunnel URL, remote client count, auth
sessions, and start/stop/QR/revoke controls. Detects tunnel clients via
Cf-Connecting-Ip header to exclude local connections from the count.

* refactor: extract SSE event handlers into named class methods
Replace ~80 inline addListener closures in connectSSE() with a
declarative _SSE_HANDLER_MAP array that drives registration in a
single loop. Each handler is now a named _on* method on CodemanApp,
making them individually addressable for LLM navigation.
Add SSE_EVENTS constant object in constants.js to eliminate magic
event-type strings scattered across the frontend.

Split 6,710-line server.ts into focused route modules using port
interfaces for dependency injection. 107/109 routes extracted into
12 domain files with auth middleware, 5 port interfaces, and shared
helpers. Server.ts retains orchestration (SSE, lifecycle, state).
