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.

A Playwright browser pass found the injected 9th App Settings tab (Users)
overflowed the non-wrapping .modal-tabs flex row and landed under the modal
backdrop (elementFromPoint returned .modal-backdrop, not the button), so a real
mouse click was intercepted. flex-wrap:wrap lets the tabs wrap to a second row;
the built-in 8-tab modals still fit on one row (no visual change).

Stamp the plan doc with shipped-by-phase status; add the multi-user Key Patterns
entry + State Files + case-spaces note to CLAUDE.md; add a multi-user section to
the security architecture (threat model: workspace separation, not a security
boundary) and a README opt-in section; add a minor changeset.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- public/admin-ui.js (new, self-contained): on boot fetches GET /api/me and
stores window.__codemanUser; installs a fetch interceptor that opens a
change-password modal on any 403 PASSWORD_CHANGE_REQUIRED (and on boot when
mustChangePassword is set); for a multi-user admin, injects a "Users" tab into
the existing App Settings modal (create/reset/disable/enable/promote/demote/
grant-bypass/delete with typed confirm + one-time-password reveal). No header
button, so the mobile-header policy stays green; nothing renders in single-user
mode.
- me-routes: GET /api/me returns a `multiUser` flag so the UI distinguishes a
single-user admin (no admin UI) from a multi-user admin.
- index.html: load admin-ui.js after settings-ui.js, before session-ui.js.
Tests: test/admin-ui.test.ts (JSDOM: identity boot, Users-tab injection gating by
role/mode, forced change-password modal, script-order wiring). Backend verified
end-to-end by test/admin-routes.test.ts against a live server. A full Playwright
pass is recommended before merge.

- routes/admin-routes.ts: GET/POST /api/admin/users, PATCH/DELETE
/api/admin/users/:username, reset-password, logout. Multi-user only (404
otherwise), requireAdmin, last-admin invariants, one-time-password on create /
reset (returned once + mustChangePassword), disable/reset/delete revoke cookie
sessions, delete kills the user's live sessions first (normal teardown) and can
delete their space (guarded). Per-user stats (live/active sessions, case count).
- web/admin-audit.ts: append-only ~/.codeman/admin-audit.jsonl (timestamp, acting
admin, action, target, IP) for every user-management action.
- SSE admin:usersChanged + auth:passwordChangeRequired (sse-events.ts + constants.js).
fix(user-store): serialize users.json read-modify-write
touchLastLogin fires on every Basic auth (fire-and-forget) and was racing route
writes (create/update), clobbering records — a real corruption bug surfaced by
the admin tests. All mutators now run under a single write lock, and
touchLastLogin is throttled to once/minute per user to bound disk churn.
Tests: test/admin-routes.test.ts (8, live server) + user-store lock verified by
the existing user-store suite.

Scopes real-time streams and the init snapshot so a multi-user client only
receives what it owns. No-op in single-user mode (identity-less clients).
- WS terminal (ws-routes): owner gate after the session lookup. A non-admin may
only attach to their own session (close 4003); the global auth hook already
ran on the upgrade and decorated req.authUser, so an unauthenticated upgrade
never reaches the handler.
- SSE (sse-stream-manager): per-client identity stored at addClient; broadcast()
and the terminal-batch flush both enforce a routing hint via canDeliver().
WebServer.broadcast auto-derives the hint (deriveSseHint): session-scoped event
families resolve the owner from the payload's session id (fail closed when the
owner can't be resolved), machine-level families (docker/tunnel/update/system/
cron) + host-plan telemetry are admin-only, everything else stays global. Raw
terminal bytes resolve the owner once and are withheld from non-owners.
- getLightState is filtered per connection AFTER the shared cache (sessions,
respawnStatus, subagents, workflowRuns by owner; scheduledRuns + planUsage
admin-only); applied to both the SSE init snapshot and GET /api/status.
- file-routes: getKnownSessionWorkingDir + getSessionAttachmentHistory (the
preview/thumbnail/history helpers that bypass findSessionOrFail) now owner-check
the session, closing a cross-user file-read path.
- GET /api/search: harvestSources is owner-scoped.
Deferred to a follow-up (documented in docs/multi-user-plan.md): away-digest +
subagent/workflow REST list scoping, push-subscription identity + routing,
per-user screenshot subdirs. The live-event versions of these are already routed
by the SSE hint; only the on-demand REST aggregates remain global for admins-only
follow-up.

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.

Adds a parallel multi-user auth branch (the single-user Basic-auth path is
left byte-identical). Off unless CODEMAN_MULTIUSER/--multiuser.
- middleware/auth.ts: mode-selecting registerAuthMiddleware. New async
multi-user hook verifies username:password against the user store (scrypt),
mints identity-carrying cookies, decorates req.authUser, enforces a per-IP
AND per-username failure bucket, and the mustChangePassword lockbox. The
hook-secret loopback bypass is now a single shared helper used by both
branches. FastifyRequest.authUser module augmentation.
- ports/auth-port.ts: AuthSessionRecord gains username/role/mustChangePassword.
- user-store.ts: verifyPassword (timing-equalized against user enumeration).
- route-helpers.ts: getAuthUser (synthetic admin fallback), canAccessOwned,
requireAdmin, revokeUserSessions; findSessionOrFail gains an optional req for
a NOT_FOUND owner check (dormant until phase 3 wires callers).
- routes/me-routes.ts: GET /api/me (synthetic admin in single-user) and
POST /api/me/password (verify current, min 8, clear mustChangePassword,
revoke other sessions).
- QR: QrTokenRecord + AuthSessionRecord carry a username; tunnel-manager
mintUserToken / consumeTokenWithIdentity / getQrSvgForCode; /q/:code binds
the cookie to the token's user (rejects identity-less tokens in multi-user);
GET /api/tunnel/qr mints a per-user token. Single-user keeps the rotating token.
- server.ts: bootstrap the initial admin from CODEMAN_USERNAME/PASSWORD on first
boot (refuse to start with no users); multi-user with >= 1 user satisfies the
non-loopback auth requirement and the tunnel-enable guard; userFailures bucket
disposal.
- types/api.ts: FORBIDDEN, PASSWORD_CHANGE_REQUIRED, USER_EXISTS, USER_NOT_FOUND,
LAST_ADMIN error codes (message + status wired).
- Session.owner field + getter/setter, SessionState.owner, MuxSession.owner,
CreateSessionOptions.owner (foundation for phase 3 ownership threading).
Tests: test/multiuser-auth.test.ts (10, live server on 3170/3171). Existing auth
suite (auth-security, qr-auth, cod54-hook-event, network-auth-policy) unchanged
and green; full test:ci sweep passes (3519 tests).

Adds Anthropic's classifier-guarded low-prompt mode (--permission-mode
auto) as a fourth ClaudeMode alongside skip-permissions/normal/allowedTools.
Wired through both spawn paths (buildPermissionArgs for direct PTY,
buildClaudePermissionFlags for tmux), the getClaudeModeConfig validator,
and the App Settings Startup Mode picker. Exports buildSpawnCommand for
test coverage.
This is the prerequisite for multi-user mode section 6.3, which downgrades
non-granted users' sessions to 'auto'.

Docker cases: seamless Claude auth (seed ~/.claude.json instead of the
corruption-prone single-file mount), full credential-store isolation for
claude + codex/gemini/gcloud/opencode (share only transcripts/rollouts,
seed the rest), auto-build the base image on first use, C.UTF-8 locale
(fixes box-drawing), collapsed/shortened Create-Case UI + short "(docker)"
case-menu tags, and w<n>-<case> tab naming for docker/remote sessions.
Also: opt-in File Viewer header button; fix a TZ-boundary flaky test.

- CLAUDE.md: rewrite the Docker cases Key Pattern to the shipped 1.4.0 state
(removes the stale "not on master / Phases remaining" framing); add
docker-quickcreate/templates/GPU/elastic-disk/export-import, the
CODEMAN_DOCKER_BRIDGE_HOOKS listener, docker state files, env vars, route +
SSE counts, and the build-agent-image command.
- README.md: new "Isolated Docker Sessions" section + a More Features bullet.
- docs/security-architecture.md: new §10 "Docker container isolation" (hardening,
commit-safe creds, blast radius, untrusted-import safety, bridge-hooks) +
Quick-reference env vars.
docs/docker-cases.md (user guide) and docs/docker-cases-plan.md (design) were
shipped with the feature.

- One-click "Run in Docker" gains an expandable settings panel with a Template
picker (Small 2G/1 · Medium 4G/2 default · Large 8G/4 · GPU 8G/4/all) plus
memory/cpu/gpu/network/image/mount-creds overrides. Any tweak creates a dedicated
per-case host; the plain checkbox keeps using the shared `default` host.
- GPU passthrough: `gpus` on DockerHost/SessionDocker -> `--gpus <value>` in create
args (needs the NVIDIA container toolkit). Elastic disk: no `--storage-opt` cap,
so container storage grows as data flows in.
- CODEMAN_DOCKER_BRIDGE_HOOKS=1: opt-in second listener on the docker bridge gateway
(auto-detected 172.17.0.1, override CODEMAN_DOCKER_BRIDGE_HOST) that serves ONLY
the hook endpoints and delegates into the secret-gated pipeline, so in-container
hooks fire on a loopback-only server. Non-hook paths -> 403; host-internal, not LAN.
Verified live: Large template applies real 8GB/4CPU limits; a secret-authenticated
hook POST from inside a container now reaches the handler (was connection-refused);
non-hook paths return 403; template UI + GPU field verified via Playwright.

- New POST /api/cases/docker-quickcreate: creates a normal case (folder in
CASES_DIR, scaffolded CLAUDE.md + hooks) AND links it to a hardened container
with default settings, auto-provisioning a shared `default` docker host — the
user never touches host/image/network fields.
- Create New tab gains a "Run in isolated Docker container" checkbox; on submit it
calls docker-quickcreate then auto-starts a claude session inside the container.
- Case Manage list gains an Export (full-image) button per docker case.
- SSE listeners for docker:exportComplete/exportFailed toast + refresh the exports
list.
Verified end-to-end on the live instance: one-click create put the case in
~/codeman-cases/<name>, auto-created the default host, launched claude in the
container; export button produces a bundle; checkbox + button render (Playwright).

Found in live testing: claude refuses its default /tmp/claude-<uid> temp dir when
that path pre-exists root-owned (happens when the workspace bind-mount traverses
it, e.g. a workspace under /tmp/claude-<uid>). Set CLAUDE_CODE_TMPDIR to a
nonexistent HOME subpath the running uid creates+owns, so docker claude sessions
are robust to any workspace location.
Also document the hook-reachability constraint: in-container hooks POST to
host.docker.internal (the bridge gateway), so they only fire when Codeman is
reachable from the container (bind 0.0.0.0 + password); on a loopback-only bind
they don't fire and idle detection falls back to output-based (which works).

Per-device App Settings > Header Displays toggles that show/hide the session
manager and away-digest header buttons (default OFF) and the cron footer
button (default ON). Adds the load/save/apply/default/displayKeys wiring in
settings-ui.js plus the marker CSS in styles.css. Client-only display keys,
stripped from the settings PUT so they never reach the strict server schema
(mirrors the showAttachmentsButton pattern); session/away stay hidden on
phones via the existing mobile.css rules. The button markup and checkbox
rows landed earlier in 5728b86.

- index.html: Create Case "Docker" tab (name/workspace/host/image/network +
advanced memory/cpus/mountCredentials/resumeOnStart), and a Docker-exports
section in the Manage tab
- session-ui.js: linkDockerCase (POST docker-host, PUT on conflict, then
docker-link; omitted optionals as undefined not null), case-picker label
"name @ container" + search fields, switchCaseModalTab/submitCaseModal docker
branch, and export/import UI (refresh/export/import/delete). Docker cases route
through /api/quick-start like remote (runClaude/runShell/runOpenCode/Codex/Gemini)
- verified in a real browser (Playwright): Docker tab renders, linking through the
UI creates the case and it appears in the picker as "uitest @ codeman-case-uitest"

- src/docker-export.ts: full-image export (pause-consistent commit + save|stream +
workspace tar + manifest -> one .codeman-container.tgz) and workspace-only; import
validates manifest + per-member sha256, traversal-guards the workspace tar, docker
load + quarantine re-tag (never overwrites a local tag). Bounded by
runWithConversionLimit; free-space precheck; docker rmi in finally; sealed
containers refuse full-image export.
- routes: POST /api/docker-cases/:name/export (background + SSE), GET/DELETE
/api/docker-exports, GET download, POST /api/docker-cases/import (-> new host+case)
- instance-scoped boot reaper (docker-hosts.reapOrphanedDockerContainers) wired after
restoreMuxSessions; never touches another instance's containers
- SSE docker:exportComplete/exportFailed/importComplete (both registries)
- fix: stream pipeline in saveImageToTar so the bundle isn't truncated
VERIFIED end-to-end on real docker: full export -> 326MB valid bundle -> delete
case -> import -> new container runs from the quarantined image with the workspace
file AND the in-image change both restored.

An in-container hook curl carries Host: host.docker.internal:<port> (the derived
CODEMAN_API_URL), so the always-on host guard must allow host.docker.internal /
host.containers.internal or every in-container hook is blocked 403. Exact-match
only; not a browser DNS-rebinding surface (resolves to the host only from inside
a container netns). Verified end-to-end: quick-start launches claude/shell in a
real container with the workspace bind-mounted and hooks scaffolded.

Release 1.3.5. Consumes the changeset from PR #155: re-issue the

screenshots-readme/, screenshots-readme-real/, screenshots-real/ and
design-explorations/ are local capture scratch that was untracked but not

Re-issue the codeman_session cookie on every authenticated request so the browser cookie lifetime tracks the server-side sliding TTL (authSessions already used refreshOnGet: true). Fixes the recurring native Basic Auth dialog during active use.
Reviewed: no token rotation (same server-generated token re-issued, so no fixation vector), forged cookies are not blessed, logout still emits only the clearing cookie and server-side invalidation holds, cookie attributes identical to the Basic Auth path. Verified against the merge result: tsc --noEmit, lint, format:check, check:frontend-syntax, check:lockfile, and npm run test:ci (3404 passed) all green.
Deterministic claude --version probe seeds cliVersion so wheel-forwarding
to Claude's transcript engages (banner scrape was unreliable on 2.1.187+
and resumed sessions). Shift+wheel reads the dominant axis so a trackpad's
horizontal Shift-scroll reaches local scrollback. New per-device
"Wheel Scrolls Local History" opt-out. Wheel reports use a fire-and-forget
send path so they no longer flicker the pending-bytes indicator.

- Hide the new btn-session-manager header button on phones: add it to the
@media (max-width: 430px) display:none block in mobile.css (next to
.btn-away-digest) and to KNOWN_PHONE_HIDDEN in the mobile-header policy
test, closing the recurring phone-header-leak regression that was PR
#153's red CI job.
- Put the session-manager header button on its own line in index.html
(was crammed onto the away-digest line).
- app.js: drop session:updated from the unified-list SSE refresh trigger —
it is batch-broadcast ~every 500ms per active session and would turn an
open modal / visible welcome list into a sustained ~1 Hz full projects
rescan loop; created/deleted (structural changes) are sufficient.
- terminal-ui.js _fetchUnifiedSessions: check the ApiResponse envelope and
throw on failure so a 5xx surfaces via the caller's catch instead of
rendering an empty history.
- terminal-ui.js _openSessionRowMenu: on re-entry, invoke the previous
menu's close fn (stored as _openRowMenuClose) so its document/window
listeners are detached rather than leaked; use claudeSessionId ||
sessionId in the 'Resume session' menu item to match the main-row and
Session Manager resume routing.

Resolve the 4 conflicted files toward master's merged #146 work while
keeping PR #153's genuinely-new additions:
- app.js: keep the full Escape chain (closeSessionManager +
closeCommandPalette + closeShortcutOverlay).
- index.html: keep master's Command Palette modal markup alongside the
PR's Session Manager modal + header button.
- styles.css: keep master's Command Palette + COD-157 shortcut CSS AND
the PR's COD-130 session-row kebab-menu CSS (both inserted at the same
spot — reunited each with its own closing brace).
- terminal-ui.js: resolve _buildHistoryItem's main-row click handler to
master's options.onActivate contract with a liveness + claudeSessionId
-aware resume default, preserving the PR's two-shape/badges/kebab body.
- panels-ui.js: the PR's pre-#146 Session Manager block auto-merged as a
duplicate AFTER master's fixed block (last-key-wins regression) — drop
it, keep master's implementation plus the PR's new
_onSessionListMaybeChanged.
Backend projectKey plumbing and the SSE live-refresh listeners in app.js
merge additively and are kept as-is.
