The feature as pitched in docs/readmymind-plan.md: pressing the header
brain button predicts the prompt you were about to type, from the case's
intent profile plus everything the session already knows.
Backend:
- readmymind-context.ts: pure budgeted context assembler (9 ranked
sources: pending approval dialog, user goals, last assistant turn tail,
recent prompts, tool activity, git workspace signals, away context,
sibling sessions, rethink state; 30 KB budget, whole-section drop from
the bottom of the ranking, trust tiers stated in the prompt)
- readmymind-collectors.ts: transcript tail reader (the live watcher
keeps only a 500-char snippet) and git signal collection (execFile,
2s timeout, skipped for remote-SSH cases)
- readmymind-predictor.ts: one-shot claude -p in a throwaway tmux
session, opus by default (readMyMindModel setting), strict JSON
contract with 1-3 suggestions (continue / verify / redirect), newline
stripping, 90s timeout; mutable singleton so route tests can stub it
- POST /api/sessions/:id/readmymind: claude-mode only (400), one
prediction in flight per session (409 CONFLICT), rethink body
{ steer, rejected }; ownership via findSessionOrFail
Frontend:
- readmymind-ui.js (loadorder 11.3): header brain button, marker-hidden
until readMyMindEnabled is ON, desktop only (phone key is phase 3);
modal with editable suggestion + rationale and Send / Insert /
Rethink / Dismiss; suggestion text rendered via value/textContent only
and nothing ever auto-sends
- App Settings -> Panels checkbox for readMyMindEnabled; en + zh-CN
strings
Verified end to end against a live isolated instance: transcript
capture, a real opus prediction grounded in the stated goals, rethink
steering, the 409, and the browser modal incl. Insert leaving the text
unsubmitted on the composer. 41 new unit/route tests; full test:ci
sweep green (4680 tests).

Per-case profiles of user intent (docs/readmymind-plan.md): user-stated goals
plus the user's recently submitted prompts, captured from the Claude session
transcript behind the new synced readMyMindEnabled setting (default OFF).
- intent-store.ts: keyed by owner + realpath(workingDir), FIFO/size caps,
consecutive-dupe collapse, atomic 0600 writes to ~/.codeman/intents.json
- transcript-watcher.ts: new transcript:user_prompt event for typed user turns
(tool_result-only entries stay silent); capture wiring in server.ts is
claude-only and gated on the setting per event
- readmymind-routes.ts: GET/PUT/DELETE /api/sessions/:id/intent, ownership
via findSessionOrFail, strict Zod schema
- agent skill: SKILL.md recipe + endpoints.md rows so agents can read and
record intent (PUT replaces: read + merge; never delete unprompted)
- groundwork for the phase-2 predictor button; nothing is ever auto-sent

Adds an Add Case -> "Clone Repo" tab plus two endpoints, implementing
@DodgyBadger's proposal in #236: clone a public repository straight into
codeman-cases/<name> and register it as a normal local case.
POST /api/cases/clone is synchronous by design (request held open, bounded
by GIT_CLONE_TIMEOUT_MS): no job store, no polling, no cancellation
surface. Success broadcasts the usual case:created event, so the case
still appears when a proxy idle-timeout kills the request mid-clone.
POST /api/cases/clone-preflight runs `git ls-remote --symref` so the UI can
say, while the user is still typing, whether the URL is cloneable without
credentials, what its default branch is, and which branches/tags exist.
Core lives in src/git-clone.ts, split into a pure half (URL parse, argv/env,
ls-remote parse, stderr classification) and a thin IO half, so every
security decision is unit-testable without spawning anything:
- `<name>::<payload>` transports are refused as a family, not by name:
ext:: is the famous one, but any of them dispatches to git-remote-<name>
and turns a clone into arbitrary command execution.
- A leading `-` is refused AND every spawn puts `--` before the operands.
Either alone is one edit away from being a hole.
- argv arrays, never a shell. URLs carrying user:password@ are refused.
- gitNonInteractiveEnv() closes all four ways git can block on a prompt
with no terminal attached (terminal prompt, askpass/GUI, ssh, GCM).
HOME/PATH stay inherited, so a user's own credential helper or ssh agent
keeps working; Codeman itself collects and stores nothing.
- The timeout signals the process GROUP, since clone fans out into
git-remote-https/index-pack children that outlive a signal to the parent.
- Bounded output (redacted stderr tail, capped ls-remote stdout, 500 refs
each) and a global 2-op pool, so N large clones cannot exhaust the host.
Repository contents beat scaffolding: an existing CLAUDE.md is kept, hooks
are merged into whatever .claude/settings.local.json the repo shipped, and
a repo that ships its own Claude settings is reported back as a warning
(those hooks run locally as soon as a session starts there). A failed clone
removes only the directory the attempt created, and refuses a pre-existing
destination outright, so it can never squat on a case name.
Not admin-gated in multi-user mode, unlike /api/cases/link: it writes only
inside the caller's own case space. Local-path/file:// sources are the
exception and stay admin-only there.
UI: live verdict under the URL field, case name filled from the parsed repo
until the user types their own, branch/tag as a datalist of the remote's
real refs, optional shallow clone, and a Brain picker (installed CLIs only)
that points the Run button at the chosen agent. Starting a session stays
opt-in. The tab hides itself when the server reports no git.
Tests: the pure half exhaustively (every refusal has a case), plus real git
against a real local bare repo for clone/ref/timeout/cleanup, and a
route-level suite with unmocked fs that clones through the endpoint.

One switch now governs the whole feature: with approvalsInboxEnabled off
(the default), sendPushNotifications strips the actions and approvalId
from permission push payloads, so the buttons no longer render at all
(pre-inbox they rendered and did nothing). The page-side action relay is
gated the same way for stale notifications sent before the toggle
flipped. Only the store and answer endpoints keep running, so enabling
the toggle surfaces anything already pending immediately.
sendPushNotifications is async now (cached settings read); all call
sites were already fire-and-forget. Covered by three new payload tests
alongside the existing hostTitle suite.

Owner decision: every Approvals Inbox UI surface (header bell, drawer,
phone overview answer strips, reload seeding) now requires enabling
approvalsInboxEnabled in App Settings -> Panels; only an explicit true
turns it on. The store, endpoints, and push Approve/Deny actions keep
running regardless (the push buttons are already opt-in per subscription).
Also replaces em-dashes with plain punctuation across the newly authored
comments, docs, and strings.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Permission dialogs, AskUserQuestion questions and idle prompts from every
session now land in a server-side inbox (web/approval-inbox.ts, one item per
session, claude-mode only) and are answerable in place: a header bell + drawer
on desktop, inline answer strips on the phone overview's NEEDS YOU rows, and
working push Approve/Deny buttons (previously dead ends, now answered straight
from sw.js with no tab open). Pending alerts survive reloads because the
frontend seeds from GET /api/approvals on init.
Answering sends the digit / Esc / prompt text through the existing tmux input
path; option digits are accepted only when they match options parsed from the
captured pane frame, and the answer path re-captures the pane first so a
dialog that already left the screen refuses with 409 instead of typing into
the composer. New elicitation_complete / elicitation_response hook matchers
resolve question items the moment they are answered in the terminal;
refreshStaleCodemanHooks heals existing cases.
Verified end-to-end against a live claude session: a real AskUserQuestion
dialog parsed into 5 option buttons and was answered from the drawer.

Ship `skills/codeman` as an installable Claude Code skill rather than a
repo-only reference, and fix six defects found while verifying it live.
Install layer:
- `codeman skill install [--case <name>]` / `codeman skill uninstall`.
Case names resolve through linked-cases.json first, mirroring the
server's resolveCasePath(), so a case linked in from outside
~/codeman-cases no longer fails with "Case not found".
- applyAgentSkill() / installAgentSkillInto() / removeAgentSkillFrom() in
hooks-config.ts. Copies are marker-owned, so an unmarked user-authored
skill is never touched, and a symlinked skill dir is refused (this
repo's own .claude/skills/codeman is a symlink to the source).
- Synced `agentSkillEnabled` setting, default OFF: schemas.ts,
ports/config-port.ts, server.ts, session-routes.ts (add-only injection
on Claude session create and quick-start), plus the App Settings toggle.
Skill content fixes, each reproduced before and after:
- Fail-closed `delete_session` replaces `is_self ... || curl -X DELETE`.
Shell state does not survive between agent tool calls, and an undefined
is_self exited 127, firing the `||` branch and deleting the caller's own
session with the one guard bypassed. The request now lives inside the
guard, so a lost preamble deletes nothing.
- clientId is a fixed literal instead of `agent-$$`. The pid changes per
tool call, so the documented resend-identical-request loop stopped being
a duplicate and retyped the prompt, submitting the turn twice.
- `last-response` is now the documented read path for claude and codex
workers. It returns clean transcript text; the terminal scrape it
replaces returns a wall of TUI repaint noise. Its transcript flush lags
the stop signal, so the recipes poll it rather than reading once.
- quick-start examples branch on `.success`. Previously a failed spawn
yielded the literal session id "null" and burned the whole readiness
budget before reporting jq noise instead of the cause.
- Documented that turning `agentSkillEnabled` off sweeps nothing, and
corrected the hooks-config comment that claimed a toggle-off sweep
exists. Per-case cleanup is `codeman skill uninstall --case <name>`.
- Documented that SESSION_BUSY means the 50-session cap on quick-start,
and that caseName resolves linked cases, so a generic name can land a
worker in a real repo.
Tests: test/agent-skill.test.ts covers install, refresh, idempotence,
marker ownership and symlink refusal against the real packaged source;
test/quick-start.test.ts covers injection behind the setting.

`reply.raw.writeHead()` writes straight to the Node response and bypasses
Fastify's header store, so everything the `onRequest` security hook granted is
silently dropped on every route that answers that way.
The visible symptom is CORS. The hook emits `Access-Control-Allow-Origin` for
localhost origins, so a page served from a local dev server may call every `/api`
endpoint cross-origin — except the four below, whose requests fail. The security
headers (`X-Content-Type-Options`, `X-Frame-Options`, CSP) were being lost the
same way.
Affected: `GET /api/events`, and `file-raw` / `tail-file` / `download` in
file-routes.ts. Each now spreads the inherited headers first and lets its own
headers win over them.
Tests drive a real WebServer and compare `/api/events` against `/api/status` for
the same Origin — the point of the fix being that the SSE route stops being the
odd one out. Verified in both directions: with the fix removed, 3 of the 5 fail.

Follow-up to #200 and #201, which gate the welcome buttons and the run-mode
dropdown on whether the CLI is actually installed. Four corrections:
1. #200 also DELETED the Cloudflare Tunnel welcome button and the QR widget
outright. Its rationale is right (offering a tunnel where cloudflared is not
installed is a bad default) but the conclusion overshoots: the welcome QR is
the whole scan-to-connect-from-your-phone flow, and deleting it left a large
block of live tunnel code in settings-ui.js driving elements that no longer
existed. Both are restored and the button is gated on cloudflared, which is
what the stated rationale actually asks for. New cloudflared-resolver.ts
mirrors the CLI resolvers, and TunnelManager now shares its search path so
the button and the spawn can never disagree about where cloudflared lives.
2. Antigravity was missing from the run-mode gating, the one run mode LEAST
likely to be installed. It slipped past because #201 predates it. Covered
now, plus a static test that fails if a sixth mode reaches the dropdown
without being gated, so the next one cannot slip the same way.
3. The per-surface fetches are replaced by the injected availability object
already used for the Codex settings tab, so the codebase has one mechanism
rather than two. The status routes buy nothing as a gating source: every
resolver memoizes its PATH probe server-side, so a fetch is exactly as stale
as an injected value while costing a round trip every time the dropdown opens
and leaving the welcome buttons to flicker in after paint. The routes
themselves stay, including the /api/claude/status that #200 adds.
4. Unknown availability now reads as AVAILABLE for run buttons. Both PRs hid the
button on a failed fetch, so a blip left a working install with nothing to
click; a genuinely missing CLI only ever produced an error toast. The Codex
settings TAB keeps the opposite default, since hiding it costs nothing.
The dropdown query is also scoped to the menu: `.run-mode-option` is the class
the saved-dashboard and history rows use too, and a document-wide querySelector
would have found whichever came first in the DOM.
Fixes a latent environment-sensitivity in 816d900 while here: the index-title
test asserted the template was untouched apart from the title, which held only
on a machine with no codex installed.
Verified end-to-end against a real server on an isolated instance+socket, with
Playwright: gemini/codex hidden and claude/opencode/antigravity/shell shown,
matching this host, tunnel button back, Codex settings tab still hidden, no
console errors. Full test:ci sweep green (3902 tests).

Both settings on the App Settings "Codex CLI" tab (bypass approvals, animated
status effects) are handed to `codex` at launch, so on an instance where the
binary does not resolve the tab offers choices nothing can act on. Gate it on
availability instead.
renderIndexHtml injects window.__codemanCodexAvailable, mirroring the existing
gesture-availability flag, and settings-ui.js hides the tab button when it is
absent. Injected rather than fetched on modal open so the tab cannot flicker in
and back out; isCodexAvailable() memoizes its PATH probe, so the per-render cost
is nil. Installing codex later needs a restart, exactly like the
/api/codex/status route that already backs the Run menu. Solo popups skip the
probe since they have no settings modal.
Only the tab BUTTON is toggled. The panel already carries
.modal-tab-content.hidden unless it is the selected tab and openAppSettings()
always reopens on Display, so an unreachable button keeps the panel unreachable.
The inputs stay in the DOM and are still populated and read back on save, so a
user without codex cannot silently wipe the codex preferences of an instance
that has it. Animations stay off by default for new local Codex sessions.
Verified in a browser on this host, which has no codex: the flag is absent, the
Codex tab is hidden while the other tabs are unaffected, and saving App Settings
with the tab hidden leaves codexAnimationsEnabled/codexDangerouslyBypassApprovals
untouched. With the flag forced on, the tab appears, its panel opens, and
toggling the visible slider persists. The openAppSettings coupling test was
checked to fail when the call is removed.

Adds Antigravity as a sixth CLI backend alongside Claude Code, shell, OpenCode,
Codex and Gemini, following the existing pluggable-resolver pattern.
- `utils/antigravity-cli-resolver.ts` resolves the CLI, mirroring the other
resolvers; `GET /api/antigravity/status` reports availability and path.
- `ANTIGRAVITY_*` joins the `ALLOWED_ENV_PREFIXES` allowlist in schemas.ts, so
env overrides stay CLI-scoped rather than blanket-forwarded.
- Session, tmux-manager, mux-interface and types carry the new mode; secrets are
injected via socket-scoped `tmux setenv`, never on the spawn command line, so
the mode requires tmux with no direct PTY fallback like the other external CLIs.
- Frontend: Run-dropdown entry, agent-type option, `ag` tab badge and toolbar
colours. `runAntigravity()` routes remote/docker cases through
`POST /api/quick-start` and skips the local status probe for them.
Tests: test/antigravity-mode.test.ts, plus run-mode-ui and system-routes coverage.

start() reassigns _claudeSessionId to `resumeSessionId || id` on every launch,
including the path that re-attaches to a mux session that outlived the restart.
A pane whose CLI had moved on via /clear therefore came back pointing the
response viewer at its pre-/clear transcript, and because Session.lastSubmitAt
lived only in memory, the history correlation had nothing to correct it with
until the user happened to type again — observed as hours of the eye showing a
conversation the pane had long since left.
Persist lastSubmitAt in SessionState, restore it in restoreMuxSessions(), and
flush it when the viewer adopts (a /clear emits no completion event, which is
the trigger that would otherwise have persisted it). Recovered panes now
re-derive their live conversation on the viewer's first poll.
Restoring a stale anchor is safe: the resolver already refuses a candidate
transcript older than the one the pane is currently on, which is the shape of a
respawn into a fresh conversation.
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,

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.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
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

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
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.

- Session: _docker field, constructor config, toState, createSessionOptions/
respawnPaneOptions (both interactive + shell paths), docker getter
- resolveMuxAttachCwd returns /tmp for docker sessions (local wrapper only execs)
- skip the LOCAL claude version probe for docker; probe the IN-CONTAINER version
instead (deferred) so wheel-forwarding stays enabled (#154)
- server restoreMuxSessions round-trips MuxSession.docker / SessionState.docker
- full CI suite green (3444 passed)

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.
