Adds a "Web / URL" section to the Run dropdown. A saved URL renders as a tab in
the same strip as Claude/Codex/Gemini sessions, with the same Alt+1..9 numbering,
so Codeman is one mission control instead of Codeman plus a pile of browser tabs.
A webview is NOT a sixth SessionMode: no PTY, no tmux, no respawn, no idle
detection. It is a separate resource sharing only the tab strip and the main
content area, the same call that keeps Docker and remote-SSH as case overlays.
Dashboards are proxied through Codeman's own origin, because a direct iframe
fails three ways at once in the shipped deployment: prod serves HTTPS behind
tailscale serve, so http:// targets are hard-blocked as mixed content (with no
override at all on iOS Safari); Grafana/Portainer-class dashboards send
X-Frame-Options: DENY; and our own default-src 'self' CSP blocks cross-origin
frames. Proxying dissolves all three and leaves the production CSP byte-for-byte
unchanged, since /webview/... is already covered by 'self'. A useful side effect:
the fetch happens server-side, so a tailnet-only dashboard is reachable from a
phone that is not on the tailnet.
The proxy is not an API surface. It authenticates on a 192-bit capability in the
path (memory-only, rolling TTL, bound to the minting user, revoked on edit or
delete) and is correspondingly exempt from the cookie and Origin checks, because
a sandboxed iframe is opaque-origin: it sends no SameSite=lax cookie and its
writes arrive with Origin: null. The Host allowlist is never bypassed. A second
Referer-keyed form of the exemption exists for root-absolute assets and is fenced
to safe methods on non-/api, non-/ws, non-/q paths.
Iframes omit allow-same-origin unless a URL is explicitly marked trusted, since a
proxied page is served from Codeman's own origin and could otherwise read this
document and drive the agent-spawning API. Authorization and codeman_session are
stripped upstream in BOTH modes, so CODEMAN_PASSWORD cannot leak into a dashboard.
Two things only a real browser reveals, both presenting as the dashboard's own
"Failed to fetch" while the page itself renders fine:
- Runtime-built root-absolute URLs (fetch('/api/data')) escape <base href> and
land on Codeman's root. Widening the Referer fallback into /api would trade
security for it, so an injected shim patches fetch/XHR/WebSocket/EventSource
inside the frame instead, removing the class rather than the guard.
- An opaque-origin document CORS-checks every request, including to the host it
was served from. Script/css/img loads are not CORS-checked, which is why the
page renders while its API calls die. The proxy now emits CORS headers and
answers preflights itself. registerSecurityHeaders answered every OPTIONS with
a bare 204 before routing, carrying no ACAO for Origin: null, so that
short-circuit now exempts a valid capability.
Neither is reproducible with curl, which does not enforce CORS.
Also fixes a pre-existing bug found on the way: .toolbar has backdrop-filter,
making it a stacking context that trapped .run-mode-menu's z-index:1000, so
.welcome-overlay painted over the whole Run menu. With no session open, every
item in it (Claude Code included) was unclickable.
Verified end to end against a real tailnet dashboard: live data, WebSocket push,
no failed requests, and switching tabs does not reload the frame. 98 new tests
cover the pure rewrite helpers, the CORS helper, the shim's rewrite logic, route
CRUD, and every edge of the auth exemption.

Resolves the CLAUDE.md paragraph conflict with #162, skips the
windowTitle recompute for solo-session renders so a detached window
cannot reset the push-notification hostTitle prefix to the default,
and prettier-formats test/mobile/devices.ts (came in unformatted via
the #162 merge; CI format:check only covers src/**).

Resolutions (sse-events.ts / constants.js / app.js): unions of the docker/
multi-user event registrations from master with the session-order/pin events
from this branch.
Additions on top of the merge:
- POST /api/sessions/:id/pin now falls back to the persisted store record when
no live session exists: COD-142 deliberately preserves pinned records after
kill (and cleanupStaleSessions skips them), so without this a pinned-then-
killed session could never be unpinned. Owner-scoped in multi-user mode.
- SessionOrderUpdateSchema bounds (id <= 100 chars, <= 500 entries) so a buggy
client can't persist megabytes into state.json; empty strings still flow to
normalizeSessionOrder which drops them.
- Route tests for the persisted-record pin fallback.

Resolutions:
- session.ts: keep the extracted _buildRespawnPaneOptions() helper (COD-108)
and add master's docker/owner fields to it
- tmux-manager.ts: docker branch first, then remote via buildRemoteSessionCommand
(now an options object threading claudeMode/allowedTools into
buildRemoteLaunchCommand, preserving the 6.3 multi-user permission downgrade)
- case-routes.ts: keep master's adminOnly helper; gate the new COD-105 discovery
endpoint admin-only in multi-user mode (hosts are machine-level infra)
- settings-ui.js: union of remoteAutoReconnect + master's header-button defaults
- session-routes.ts: union of imports; session gets remote + owner

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.

- 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'.

- 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.

- 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

/api/docker-exports, GET download, POST /api/docker-cases/import (-> new host+case)

restoreMuxSessions; never touches another instance's containers

- fix: stream pipeline in saveImageToTar so the bundle isn't truncated
VERIFIED end-to-end on real docker: full export -> 326MB valid bundle -> delete

A killed session was full-deleted from state.json (removeSession),
dropping the COD-139 pinned/pinnedAt fields, so the session vanished
from the session-manager pinned group. cleanupStaleSessions also reaped
any persisted record with no live session on boot, which would have
wiped a preserved pin on the next restart.
Fix (state-store):
- demoteOrRemoveSession(id): on kill, demote a *pinned* record to a
lightweight stopped record (status=stopped, pid=null, pin retained)
instead of deleting; unpinned records are removed as before.
- cleanupStaleSessions skips pinned records so the pin survives restart.
- server _doCleanupSession calls demoteOrRemoveSession on the killMux
path (shutdown path unchanged).
Restoration iterates live mux sessions, not state.json, so a stopped+
pinned record is never auto-revived. Unit-tested on the real StateStore
path (state-store.test.ts +4); session-cleanup/session-pin regress green.
(cherry picked from commit 86f183eacfc3f2f6ac28499fb1ae2d21eef2bbed)
Tab reordering (drag-and-drop + Ctrl+Shift+{/}) persisted only to
localStorage (codeman-session-order), so each device kept its own private
order. Add server-side persistence so the order follows the user across
devices, live. Takes the issue's recommended default (a): one global order,
server authoritative, localStorage as offline fallback.
- session-order.ts (new, pure + unit-tested): normalizeSessionOrder (coerce
to string[], drop empty/non-string, dedup) and mergeSessionOrder (the
pushing device's order wins; ids the device hadn't loaded fall to the end
in their existing relative order, never dropped — graceful for
closed/remote/parked sessions absent on that device).
- AppState.sessionOrder?: string[]; StateStore get/setSessionOrder + the field
added to buildPartialJson() (the incremental serializer whitelists fields,
so without this the value never reached disk / survived a restart).
- PUT /api/session-order (session-routes): parse -> merge -> persist ->
broadcast session:orderChanged; getLightState() init snapshot now carries
sessionOrder so a fresh load/reconnect restores it.
- SSE event session:orderChanged registered in sse-events.ts + constants.js.
- app.js: handleInit seeds localStorage from the server snapshot before
syncSessionOrder(); saveSessionOrder() also PUTs to the server (debounced
400ms, covers drag + both keyboard moves); _onSessionOrderChanged adopts a
remote order and re-renders (no-op-guarded to avoid echo flicker).
Verified (orchestrator re-ran all gates): tsc 0, lint 0, frontend-syntax +
prettier clean, build ok; session-order + session-order-routes + state-store
56/56. Functional round-trip on an isolated beta: PUT {a,b,c} -> status
snapshot reflects it; merge PUT {c,a} vs {a,b,c} -> {c,a,b} (b preserved at
end); malformed payload rejected with a clean 400; sessionOrder persisted to
state.json and survived a restart.

(cherry picked from commit 79415f2fdfbdf3fbe362a063534e7f84c553eefb)
Continuous remote-only reconnect watcher closing the COD-104 durability
arc: when a remote session's local ssh pane dies mid-run, re-establish it
automatically instead of leaving a dead pane until the user pokes it.
Design decisions (per cod108 design doc):
- D1 event->owner: TmuxManager watcher DETECTS a dead remote pane and emits
`remoteSessionDropped`; the session owner (server) reassembles the same
RespawnPaneOptions and calls Session.reattachRemote() -> respawnPane, which
re-runs the idempotent remote command (owned new-session -A / non-owned
attach) and REJOINS the still-running durable remote tmux session. The
watcher never reassembles options itself, and never routes through the
Claude-idle respawn-controller.
- D2 bounded backoff: per-session exponential backoff [5s,15s,45s,2m,5m,5m],
reset on a successful reattach, `remoteReconnectExhausted` emitted once after
the cap. Pure, unit-tested schedule + eligibility decision.
- D3 always-on + kill-switch: `remoteAutoReconnect` app setting (default ON),
read each tick; when false the watcher does nothing.
Guards: killSession() (incl. the non-owned DETACH early-return) and shutdown
add the session to an intentional-teardown guard set + clear its backoff
BEFORE teardown, so a closed/killed tab is never auto-revived. Exactly one
reconnect in flight per session (inFlight guard prevents stacked respawns).
Per-session reconnect/guard state cleared on session removal.
New: src/remote-reconnect.ts (pure backoff + decideReconnect), TmuxManager
startRemoteReconnectWatcher/stop + runRemoteReconnectTick + noteRemoteReconnect
+ guardRemoteReconnect + clearRemoteReconnectState; Session.reattachRemote()
(+ extracted _buildRespawnPaneOptions, shared with interactive start); server
wiring + watcher start; 3 SSE events (sse-events.ts + constants.js in sync,
broadcast + app.js exhausted "Reconnect" affordance); remoteAutoReconnect
schema + settings-ui toggle.
Tests: test/remote-auto-reconnect.test.ts (21) - pure schedule, eligibility
(guarded never reconnects, non-remote/pane-alive/not-due skip, over-cap
exhaust), and manager-level integration (dead remote pane -> dropped ->
backoff -> exhausted; guarded emits nothing; reset-on-success; kill-switch
off; state-cleared-on-remove). Verified real-remote against aa-desktop: drop
local ssh pane -> watcher emitted -> respawnPane reattached the SAME remote
session (remote pane_pid unchanged 3939->3939); test session cleaned up, the
real host sessions left untouched.
Checks: tsc, eslint, check:frontend-syntax, check:public-assets, prettier
--check, build all green; tmux-manager/session-routes/session-manager/
sse-registry-parity suites pass.
(cherry picked from commit d13d58b1994eb6594fd2eadea208104d36204f9d)
- UI: add the missing data-tab="case-remote" tab button; dispatch it through
submitCaseModal()/switchCaseModalTab() to linkRemoteCase() (was dead code).
- Restore: restoreMuxSessions() now passes remote (muxSession.remote ??
savedState.remote) into the Session constructor, so remote metadata round-trips
on restart instead of reattaching from a local cwd / respawning LOCAL / being
erased from state.json. Recovery tests added.
- Run flows: runClaude()/runShell() route remote cases through /api/quick-start
(POST /api/sessions stat-validates workingDir locally); run*() skip the
/api/*/status pre-check and omit inert config/env for remote cases.
- Quick-start: resolve the remote case BEFORE the local CLI availability gates and
skip isCodex/Gemini/OpenCodeAvailable() when remote; REJECT
envOverrides/effort/codex/gemini/openCode config for remote (they don't cross
ssh) instead of silently dropping them.
- Injection: reject $, backtick, $( in remotePath + identityFile at the schema
layer (they survive shellescape into the bash -c launch double-quote layer).
Regression tests for $(...) and backtick payloads added.
- Remote socket/name: launch on a DEDICATED -L codeman-remote socket under a
codeman-ssh-<id> name that fails a remote Codeman's SAFE_MUX_NAME_PATTERN, so a
remote instance can't adopt the session; scope tmux set-options per-session
(never -g) so they don't mutate other sessions.
- Kill: best-effort ssh 'tmux -L codeman-remote kill-session' on remote session
kill (fire-and-forget, never blocks/throws the local kill) so the remote agent
isn't orphaned forever.
- Probe: wire checkRemoteTmuxAvailable() into POST /api/quick-start (structured
OPERATION_FAILED) and as courtesy validation in remote-link; add a default
-o ConnectTimeout=10 to buildSshConnectionArgs (overridable via extraSshOptions).
- Command default: remote claude default is now
'exec claude --dangerously-skip-permissions' (per-host override stays the escape
hatch), mirroring local non-interactive semantics.

- 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.

- Pass the attachment request `source` through the server deps lambda and make
it a required param on SessionListenerDeps.registerAttachment + the wiring
event type (the 2-arg lambda silently dropped `source`, force-confining every
codex-generated artifact — the feature never worked outside the workspace);
new test/session-listener-wiring.test.ts asserts the pass-through
- Gate the Codex `Saved to: file://` scanner on mode === 'codex' via a
codexArtifacts option threaded from the session call site; magic links stay
mode-agnostic; tests assert claude/shell sessions never emit codex-generated
requests
- Decide the generated-artifact trust policy on the realpath-RESOLVED path
(unresolvable → force-confined) and anchor the ~/.codex marker dirs to
os.homedir() prefixes with startsWith instead of substring matching; symlink
escape + unanchored-marker regression tests added
- Run the Codex scanner on stripAnsi'd data so trailing SGR sequences don't
ride into the captured URL; styled 'Saved to:' test added
- Extend generateFirstPageThumbnail with jpg/jpeg/gif/webp passthrough and
per-extension content types (mirrors the png passthrough) so the PR's new
image formats render real thumbnails instead of 204 letter-tiles

Three independent root causes of intermittent Chinese character loss
(English was unaffected because it bypasses the composition path):
1. input-cjk.js state machine: stuck _composing when compositionend never
fires (WeChat/Sogou IMEs) silently swallowed all input; the deferred
compositionend flush could reset the textarea mid-next-composition
(cancels the live IME composition on iOS); the 100ms keydown-echo
window discarded ANY input regardless of content.
2. Focus stealing: session-select / SSE-reconnect paths call
terminal.focus() (15+ call sites), landing focus on xterm's hidden
textarea; with the CJK onData gate active, everything typed there was
swallowed. Fix: focus router in initTerminal routes ALL
terminal.focus() calls to the CJK field while it is visible, plus a
self-healing onData gate that reclaims focus when it swallows input.
3. Android InputConnection wedge (9-key IMEs + Chromium): the keyboard
composes in its own UI but delivers zero DOM events. Fix: skip
redundant textarea value/selection writes (they race IME session
setup), and re-tapping the focused empty field forces a blur→focus
cycle that restarts the input session.
Diagnostics: input-cjk.js now traces every IME event/flush decision into
the crash-diag breadcrumbs; /api/crash-diag stores beacons per page-load
id (iOS PWA reloads no longer wipe the trail, concurrent clients no
longer clobber each other) and flushes on visibilitychange.
Tests: test/input-cjk.test.ts (vm-sandbox, 9 cases incl. regression
guards for all three root causes).
Introduce src/config/terminal-history.ts: one place for terminal scrollback,
tmux history-limit, and PTY buffer byte caps, each overridable via env var or
the settings object and bounds-clamped via resolveTerminalHistoryConfig().
Defaults match the prior hardcoded values, so this is behavior-neutral. Wires
the resolver through buffer-limits, tmux-manager (incl. a setHistoryLimit so a
settings change applies live), session, server, system-routes, session-routes,
schemas, and the config port. Adds 4 optional settings keys (terminalScrollback
Lines, tmuxHistoryLimit, terminalBufferMaxBytes, terminalBufferTrimBytes) with
bounds + a trim<=max cross-check.
Rename the recurring-jobs feature scheduler->cron to disambiguate from the
legacy ScheduledRun system (/api/scheduled), which is left untouched:
- ScheduledJob->CronJob, SchedulerService->CronService
- /api/scheduler/jobs -> /api/cron/jobs; SSE scheduler:* -> cron:*
- state keys cronJobs/cronJobRuns
- files moved to src/cron/, cron-routes.ts, cron-port.ts, types/cron.ts
- frontend cron-ui.js, #cronModal, menu "Cron"
- docs moved to docs/cron-discovery.md + docs/cron-build-brief.md, README guides
- new tests: cron-service.test.ts, cron-time.test.ts
Green: tsc, lint, frontend-syntax, format, 30 cron + 9 legacy scheduled-runs tests.

Adds a saved/named scheduling layer on top of Codeman's existing session
primitives. Distinct from the legacy run-now ScheduledRun concept.
- types/scheduler.ts: ScheduledJob + ScheduledJobRun
- state-store: persist scheduledJobs/scheduledJobRuns in ~/.codeman/state.json
- scheduler/scheduler-time.ts: pure once/interval/daily/weekly next-run math
- scheduler/scheduler-service.ts: CRUD, Run Now, due-checker tick, run history;
reuses SessionPort (create -> start -> writeViaMux) for launches
- web/routes/scheduler-routes.ts: /api/scheduler/jobs CRUD + run + history
- web/schemas.ts: zod validation with schedule-type-aware refinements
- web/sse-events.ts: scheduler:* events
- server.ts: wire service into route context + 30s background tick loop
- test/scheduler-time.test.ts: 14 unit tests for next-run calculations
Phase 1 discovery recorded in SCHEDULER_DISCOVERY.md.

The mobile copy/paste overlay's "🖼 Image" button (and drag-drop / paste)
now handles real-world photo batches:
- Up to 20 images per batch, uploaded with bounded concurrency (3) and a
live "Uploading N/M…" progress toast; a final summary reports successes,
any failures, and whether the 20-cap trimmed the selection (no silent
truncation).
- Per-file upload limit raised 10MB → 50MB (MAX_PASTE_IMAGE_BYTES in
buffer-limits.ts, env-overridable) so full-resolution phone photos and
large screenshots aren't rejected.
- Very large images are downscaled to <=4096px longest edge before upload:
fixes iOS Safari's ~16.7M-px <canvas> limit (which made huge photos fail
to re-encode and fall back to an original that tripped the magic-byte
check), and keeps batch uploads fast and small.
- Fix a latent concurrency bug the batch path exposed: the first parallel
uploads to a session raced on `mkdir(.claude-images)` and the EEXIST
losers 500'd. mkdir now treats an existing real directory as success
(re-verifying it isn't a planted symlink), so concurrent uploads succeed.
Verified end-to-end in a real browser (Playwright): downscale, >10MB
server acceptance, 20-cap, 20/20 concurrent uploads landing on disk.

Auto-popping draggable window per active ultracode/Workflow run, connected by a
glowing line to its originating session tab (resolved via claudeSessionId ===
sessionUuid). Mirrors the live agent grid; auto-closes after a run finishes;
dismissals are remembered. Additional to the existing docked panel.
New "Ultracode Floating Windows" setting (default OFF), independent of the
"Ultracode Agents" panel toggle; either toggle starts the workflow-run watcher.
Also bumps version to 1.1.3 and brings CLAUDE.md up to date for the ultracode
subsystem.

Opt-in (showUltracodeAgents, default OFF) panel that visualizes ultracode /
Workflow-tool runs like Claude Code's "working agents" TUI: LEFT = runs + phases
(selectable tasks), RIGHT = each run's agents with model, live state, tokens
burned, and tool calls.
Standalone — ZERO edits to subagent-watcher.ts. A new workflow-run-watcher.ts
singleton globs the run-state tree (~/.claude/projects/*/*/workflows/wf_*.json,
disjoint from the transcript tree), strips the heavy script/scriptPath/result/logs
fields (174KB -> ~25KB/run), and emits workflow:run_* SSE events. The LEFT list
ships lightweight summaries (getLightState replay + SSE); the RIGHT pane fetches
the full run (with agents[]) via GET /api/workflows/:runId on selection.
Backend: workflow-run-watcher.ts, types/workflow-run.ts, config/workflow-config.ts,
3 SSE events, getLightState workflowRuns replay, GET /api/workflows[/:runId],
showUltracodeAgents schema key + boot-gate (default OFF) + live toggleService.
Frontend: ultracode-panel.js (debounced master-detail render, run/phase select),
header launcher (btn-ultracode-agents--hidden marker -> mobile-guard-exempt),
App Settings toggle (SYNCED, deliberately not in displayKeys).
Agent states on disk are start|progress|done (start=queued; done has
durationMs/resultPreview). Tests: workflow-run-watcher (9), workflow-routes (3).
Verified: tsc/lint/prettier/frontend-syntax/public-assets/mobile-header-guard
clean; full test:ci green (2986 passed); live server + Playwright e2e against 25
real runs (28-agent grid, phase filter, OFF hides launcher).
Design: docs/ultracode-agent-viz-plan.md (rev. 3).

The plan-usage header chip (5h/7d %) was a SYNCED setting, so enabling
it on desktop turned it on for mobile too — even though the user never
enabled it there. Make the chip's DISPLAY purely per-device (default
OFF) like the response viewer / skin, while keeping telemetry COLLECTION
server-side.
Three leak sources fixed:
- server.ts renderIndexHtml force-revealed the chip from the synced
value (pre-paint), pushing the desktop choice onto every device.
Removed — the chip now ships hidden and the client reveals it
per-device via applyHeaderVisibilitySettings.
- settings-ui.js load-merge let the server value win, writing desktop's
`true` into the (separate) mobile settings blob. showPlanUsageLimits
is now a displayKey AND is dropped from the server payload on load, so
a stale server value is never seeded into a device that didn't enable
it. It's also stripped from the save payload so a mobile "off" can't
clobber the server.
- Collection was gated on the same synced flag. Decoupled via a new
`statusLineTelemetry` ACTION field (schema + system-routes): sent on
ENABLE only and never persisted, so the exporter is injected when a
device turns the chip on but is never yanked when another device has
it off (it's shared across sibling sessions). Session-create already
reads the per-device blob, so that path was already correct.
One-time migration clears a stale synced `true` from the mobile blob so
existing mobile installs default to OFF without a manual toggle.
Verified end-to-end on an isolated server: with showPlanUsageLimits=true
persisted, the rendered HTML ships the chip hidden; a fresh browser
context (mobile case) keeps it hidden while a context that explicitly
enabled it shows it; the PUT accepts statusLineTelemetry and does not
persist it. tsc + frontend-syntax + system-routes/index tests green.

COD-54 gated the /api/hook-event + /api/status-telemetry localhost bypass
behind the shared X-Codeman-Hook-Secret only WHILE a managed tunnel was
running, keeping a plain localhost bypass otherwise. But Codeman can't detect
a user's OWN loopback reverse proxy (their own `cloudflared --url`,
`tailscale serve`, nginx -> 127.0.0.1), which proxies internet traffic into
the loopback origin with req.ip === 127.0.0.1 — so that setup kept the unsafe
plain bypass.
Require the secret on the loopback bypass unconditionally. Managed-session
hooks already always present it (X-Codeman-Hook-Secret from
$CODEMAN_HOOK_SECRET_FILE, generated for every instance), so the legitimate
hook channel is unaffected; only the previously-unguarded own-proxy path is
now rejected. Drops the now-unused getTunnelRunning param from
registerAuthMiddleware.
Tests: cod54-hook-event-auth (tunnel-down now also requires the secret, plus
a good-secret positive case); auth-security (hook tests present the secret to
reach schema validation).
Stacks on COD-38: accumulates a per-session attachment history and exposes it
through a slide-in drawer with an unread badge, so attachments stay reachable
after their cards are dismissed.
Backend:
- session-attachment-history: history state — dedupe by source path / relative
path, newest-first, 100-item cap, and externalPath sanitization (the absolute
host path is server-private and never leaves toState()).
- session.ts: _attachmentHistory + getter (sanitized) / upsert / restore /
getAttachmentHistoryForPersist; restored from saved state in the constructor.
- file-routes: GET /attachments (list — resolves each entry to live metadata +
routes; external entries are re-registered) and GET /attachments/:id
(metadata poll). The by-id route guards via the registry's TOCTOU-safe
resolveServableAttachmentPath.
- server.ts: detected/registered attachments upsert into history and persist;
the private (externalPath-bearing) history rides on disk under
__attachmentHistory, separate from the sanitized public copy, and is restored
on mux-session recovery.
- types/session.ts: SessionAttachmentHistoryItem + SessionState.attachmentHistory.
Frontend:
- panels-ui: the drawer (lazy-built), unread badge, list render with per-item
preview/download/open/"Card" (reshow) actions, and live refresh of the open
drawer on new detections.
- app.js: history state + per-session badge/cleanup wiring.
- index.html / styles.css / mobile.css: header button + badge and the drawer.
Verified: tsc / eslint / prettier / frontend-syntax / public-assets clean; new
history-module unit tests pass; full test:ci green (2866 passed); badge, drawer
open/render/reshow/close verified in-browser.
Review of the plan-usage chip feature (commits since 1.0.0) surfaced several
issues; this fixes all confirmed findings:
- HIGH: applyStatusLineConfig clobbered a user's hand-authored statusLine on
the enable path (the isOurs guard only protected disable). Now bails out when
an existing statusLine isn't ours, on both the enable and disable paths.
- MED: StatusTelemetrySchema used z.optional() (rejects null) on Claude's
undocumented statusline fields — a single stray null 400'd the entire POST and
silently killed the chip's data feed. Switched the modeled fields to .nullish().
- MED: dropping the Token Count / Show Cost header toggles left their features
reading settings.showTokenCount/showCost, but saveAppSettings rebuilds settings
fresh from the DOM, dropping those keys and resetting them to defaults on every
save (re-enabling the token chip with no UI to turn it off). Preserve the prior
stored preference.
- telemetrySignature keyed on contextUsedPercentage (never displayed) and the raw
unrounded %, churning a redundant SSE broadcast + localStorage write + identical
chip re-render on every assistant message. Now keys on the rounded displayed
window values only.
- Plan-usage chip flashed hidden on load (no server-side reveal): renderIndexHtml
now strips header-plan-usage--hidden when enabled, matching btn-multimonitor;
fixes the FOUC and makes the "server renders initial state" comments accurate.
- Serialize all settings.local.json read-modify-write writers in hooks-config via
a shared per-path mutex (previously lock-free; concurrent session-create +
settings-toggle on the same repo could lose writes).
- Hardened the chip's innerHTML against any future string field; removed the dead
_latestPlanUsage field; clamped ctx% in the footer formatter; corrected the
session-create comment (the path is add-only by design — a per-repo settings
file is shared by sibling sessions).
- Tests: new test/routes/status-telemetry-routes.test.ts (route behavior, dedup,
null-tolerance) + NaN/Infinity/fractional and signature-churn unit tests; made
server-index-title.test.ts deterministic against the ambient settings.json.

The header chip previously only repopulated on reload from per-browser
localStorage, so a fresh browser (or cleared storage) stayed blank until a
session next rendered telemetry. Store the latest broadcast telemetry
process-wide (plan-usage-latest.ts) and include it as `planUsage` in
getLightState — the per-connection SSE init snapshot — so handleInit paints
the chip immediately on every fresh load / reconnect, authoritative over the
localStorage restore. Null until the first telemetry of the process.

End-to-end testing on the real install surfaced several issues the unit
tests missed:
- Injection gate excluded real sessions: gated on workingDir under CASES_DIR,
but sessions run in linked cases / real repos. Drop the gate (match
updateCaseModel, which writes settings.local.json unconditionally).
- statusLine curl failed on HTTPS: prod is loopback HTTPS with a self-signed
cert; `curl -s` returns 000. Use `curl -sk` (loopback only). applyStatusLineConfig
now also updates an out-of-date ours-command so the fix propagates.
- Footer hijacked by limits: the in-terminal statusline now shows CURRENT
SESSION status — `Opus 4.8 (1M context) in:562,411 out:1,188 ctx:56%` —
while the account-wide plan limits live only in the header chip.
- Chip blank after reload: persist last-known to localStorage and restore on
load (account-global, slow-moving; 12h freshness guard).
- Readability + color: per-window green/yellow/red by usage (<60 / 60–84 / ≥85),
bolder labels and values.
- Drop the renderIndexHtml strip (client-side reveal only, response-viewer
pattern) — fixes server-index-title test fragility to local settings.
Footer fields flow through context_window.total_input_tokens/total_output_tokens
(schema + parser). Tests updated; verified live (footer, chip, colors, reload
persistence) on the real install.

Surface Claude subscription plan usage limits (5-hour rolling + 7-day
weekly: percent used + reset time) in the header, opt-in via App Settings
→ Display → "Plan Usage Limits" (default OFF, no behavior change when off).
A Codeman-managed Claude statusLine exporter forwards the rate_limits JSON
to a new auth-exempt POST /api/status-telemetry (same loopback + hook-secret
gate as /api/hook-event); parsed telemetry broadcasts over SSE
session:statusTelemetry to a header chip (amber >=80%, red >=95%, reset
times on hover). The exporter prints the same summary back as the
in-terminal footer (print-through).
- src/usage-telemetry.ts: pure parser/formatter (epoch-sec -> ms, clamp,
change signature) + test/usage-telemetry.test.ts
- hooks-config.ts: generateStatusLineCommand + applyStatusLineConfig
(add/remove; never clobbers a user's own statusLine)
- session-routes.ts: inject gate (Claude-only, Codeman-managed cases),
driven by create-payload statusLineTelemetry (session-ui.js)
- schemas.ts: StatusTelemetrySchema + showPlanUsageLimits + payload field
- frontend: header chip, applyHeaderVisibilitySettings toggle,
renderIndexHtml strip, _onSessionStatusTelemetry handler
Schema empirically confirmed against Claude Code 2.1.177 (Claude Max):
only five_hour/seven_day windows exist (no Opus-weekly field); rate_limits
is absent before the first API response and for non-subscriber auth. Design
+ verification method in docs/usage-limits-display-plan.md.

Builds on the COD-37 registry: surfaces detected/registered attachments as
dismissible cards with a first-page thumbnail and an inline preview — the
consumer the registry PR deliberately deferred.
Backend:
- document-thumbnailer: first-page PNG thumbnails (PNG passthrough; PDF via
pdftoppm; Office via the preview cache).
- document-preview-cache: disk-cached DOCX/PPTX -> PDF conversion (LibreOffice
/ PowerShell COM), in-flight dedup, multi-converter fallback.
- file-routes: serveConvertedPreview / serveThumbnail + four routes —
GET .../attachments/:id/preview, .../thumbnail and the workspace-path
file-preview / file-thumbnail. Reuses the registry's TOCTOU-safe
resolveServableAttachmentPath, so previews stream the freshly-resolved path.
- server: enrich detected attachment events with a thumbnail route.
- image-watcher: .png now routes to attachment:detected — this PR adds the card
consumer, so the screenshot popup is no longer its only handler.
Frontend:
- panels-ui: attachment cards (addAttachmentCard, lazy stack, Clear-all,
per-session cleanup) plus a 3-arg openFilePreview that renders registered
attachments inline (image/PDF) or via the server-converted PDF (docx/pptx).
- app.js: wire attachment:detected -> _onAttachmentDetected and card state.
- styles: attachment-card + stack styling.
Verified: tsc / eslint / prettier / frontend-syntax clean; new thumbnailer +
preview-cache unit tests pass; full test:ci green (2861 passed); card render +
preview overlay + dismiss verified in-browser.
Security (MAJOR): the terminal-output codeman://attach scanner registered any
matching path server-side with no user confirmation and broadcast the rawUrl
over SSE. Terminal output is attacker-influenceable (a prompt-injected session
can print an arbitrary path), so on the default no-auth deployment this was an
arbitrary host-file (png/pdf/docx/pptx/md/txt) read primitive reachable by any
SSE client. Magic-link registration is now force-confined to the session
workspace (forceWorkspaceConfinement) regardless of the global confine setting;
deliberate cross-workspace attach still works through the explicit,
Origin-guarded POST /attachments route and 'codeman attach' (which POSTs
directly inside a managed session). Documented in security-architecture.md.
Regression (MAJOR): .png was rerouted from the image-popup path to
attachment:detected, which has no frontend consumer — silently breaking the
dropped/pasted-screenshot popup. PNG stays on image:detected; only pdf/docx/pptx
(which never had a popup) emit attachment:detected.
Also:
- raw route streams the freshly-resolved path, not the stored one, so a
post-registration symlink swap can't redirect the stream (TOCTOU).
- 50MB cap on the attachment raw route, matching file-raw / download.
- per-session attachment registry cap (200) to bound the POST path.
- CLI reads creds via dataPath('.env'), honoring CODEMAN_INSTANCE.
Tests: forced-confinement reject/allow cases; PNG popup-path assertions updated.
Adds the foundation for serving local files to the browser as live external
attachments with a stable id, so requests never carry arbitrary absolute paths.
- attachment-registry: in-memory, session-scoped registry. registerExternalAttachment
validates an absolute path, resolves symlinks, enforces the path guard, and mints
an `att_<uuid>` id; records are cleared when the session is removed.
- attachment path guard: a configurable blocklist (secret locations + /root,/etc
trees, extendable via attachmentBlockedPaths / CODEMAN_ATTACHMENT_BLOCKED_PATHS)
plus an optional, default-off workspace-confinement mode. Shares one
sensitive-path blocklist (web/sensitive-path.ts) with /api/download, which is
refactored to use the extracted module instead of an inline copy.
- terminal magic links: the session scans output for codeman://attach?path=... and
emits `attachmentRequested`; the web server registers the file and broadcasts an
`attachment:detected` SSE event. `codeman attach <path>` (CLI) prints the magic
link or POSTs directly when a session id is known.
- image watcher: detects png/pdf/docx/pptx dropped into a session's working dir and
emits `attachment:detected`.
- routes: POST /api/sessions/:id/attachments (register) and
GET /api/sessions/:id/attachments/:attachmentId/raw (serve), both re-checking the
guard before streaming.
Document previews/thumbnails and the attachment-history drawer build on this
foundation and land separately.
Verified: tsc --noEmit, lint, format, frontend-syntax, full test:ci (2846 passed),
and a server boot smoke (/api/status 200).
