Switching away from a session and back replayed only the server's byte
history. For TUI modes (codex especially) that shows just the latest
repaint — the idle banner — because the TUI drops earlier conversation
from its current frame. This restores the actual on-screen view.
Two complementary mechanisms:
- Client: load xterm's SerializeAddon and snapshot the rendered state
(viewport + scrollback + colors) per session on switch-away, restoring
it for an instant first paint on switch-back. The snapshot is only the
first paint — the canonical /terminal frame is still fetched and
reconciled (restoredSnapshot/clearedForBusy force the replay). Snapshots
are LRU-bounded in memory (<=20) and persisted to localStorage
(<=256KB each, <=10 sessions, stale-pruned) so they survive tab discard.
- Server: GET /api/sessions/:id/terminal prepends the live tmux pane
buffer (via the existing captureActivePaneBuffer) ahead of the byte
history, cleared between, so replay reflects the current frame.
Also fix formatPaneSnapshot dropping the rightmost column of every
captured row: it painted to cols - 1 out of caution about last-column
autowrap, but every row is followed by an absolute cursor-position CSI
that cancels xterm's pending-wrap, so painting the full width is safe.
The SerializeAddon is built from @xterm/addon-serialize (new dependency)
into the vendor bundle by postinstall.js (dev) and build.mjs (prod),
matching how the other xterm addons are vendored.
Auto-resume on usage limit ("token pause" control, opt-in checkbox at the
top of the Respawn tab, off by default):
- usage-limit-patterns.ts (new, pure): detects all Claude Code limit
messages (1.0.x-2.1.x eras incl. "5-hour limit reached - resets 8pm",
"You've hit your limit - resets 1:40pm (TZ)", weekly date forms, raw
"usage limit reached|<epoch>") and parses the reset time. Conservative:
no parseable future reset time, no action.
- SessionAutoOps: arms a timer at reset+2min, sends Esc (dismisses the
rate-limit dialog) + "continue"; dedups footer redraws, retries every
5min on stale times, cancels when Claude starts working, persists and
re-arms across Codeman restarts (SessionState.autoResumeEnabled/At).
- Respawn guard: cycles are blocked while limit-paused so /clear cannot
wipe the paused conversation (respawnBlocked reason 'usage_limit').
- POST /api/sessions/:id/auto-resume; SSE session:limitPauseScheduled/
limitResume/limitResumeCancelled; toasts + status line in the modal.
- Respawn tab tidied: single-row prompt fields, merged behavior row.
Mobile fixes (0.9.8 regressions, user-reported):
- Resize arbitration is now activity-based: a desktop sizing claim only
blocks phone resizes while the desktop typed within 90s
(Session.DESKTOP_CLAIM_IDLE_MS). Idle desktop -> phone takes the pane;
next desktop keystroke re-asserts the desktop layout server-side
(noteDesktopActivity via ws-routes input). Phones re-send dims every
30s (visible tab only, skipped while the keyboard is open) so attaching
under a hot claim self-corrects. Fixes the desktop-width-stream-in-
narrow-xterm soup (mid-word wraps, tmux dot fill, Ink overdraw).
- Cross-device reflows (takeover/re-assert) emit a debounced needsRefresh
so all clients reload the buffer instead of stacking ghost Ink frames.
- Keyboard accessory/toolbar lift restored: measure keyboardOffset
against window.innerHeight (layout viewport), not the shrunken .app -
on iOS the offset computed to 0, leaving both bars hidden behind the
OS keyboard with a dead gap above.
- Removed the mobile header utility ("three dots") toggle entirely;
the headerRight tray stays collapsed on small viewports.
Tests: usage-limit-patterns (36), session-auto-resume (21), resize
arbitration (+6), session routes (+4), respawn guard (+2); MockSession
auto-resume/sizing stubs; mobile tabs test updated for toggle removal.

Mobile-focused fixes for the web UI: keyboard-accessory layout and
overlap, native input visibility above the keyboard, CJK input handling,
terminal touch scrolling, tab-menu tap targets, mic-recording glow
containment, and mobile resize/keyboard-state handling on tab switch,
plus mobile visual-regression test coverage and snapshots.

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

* fix(test): share route error handler with test harness + fix stale assertions
The route test harness built a bare Fastify instance without the production
global error handler (server.ts), so structured errors thrown by route helpers
(findSessionOrFail → 404, parseBody → 400) fell through to Fastify's default
handler — yielding a `{statusCode,error,message}` body instead of the
`{success:false,...}` shape, and the tests asserted the old implicit-200
behavior. 51 route tests across 7 files were red.
- Extract the handler into src/web/route-error-handler.ts; server.ts and the
test harness now install the identical handler (single source of truth).
- Correct stale assertions across route test files: throw-based error paths
now assert 404 (unknown session) / 400 (invalid body); genuine in-handler
`return createErrorResponse(...)` paths (200 + success:false) left untouched.
- Reformat a few test files prettier flagged (pre-existing non-compliance).
Route suite: 307/307 passing (was 256/307). No production behavior change.
* test(respawn): mock child_process so AI checker never spawns real processes
respawn-controller.test.ts drives the AI idle checker (ai-checker-base), whose
runCheck() spawns a real `tmux new-session` running `claude -p`. The AI-enabled
tests only assert the ai_checking state transition (then cancel/stop), so the
spawn produced stray real tmux sessions and claude processes on every run — the
reason `npm test` (full suite) was unsafe to run inside a managed session.
Mock node:child_process here (mirroring ai-idle-checker.test.ts), spreading the
real module so `exec` stays intact for transitively-imported modules
(tmux-manager calls promisify(exec) at load). With this, the full non-mobile
suite runs without spawning any real tmux/claude.

* fix: isolate codeman tmux sessions
* fix(tmux): unify all sessions onto a single dedicated socket
Remove the per-session `tmuxSocket` field that recorded which tmux server
each session lived on (default vs the `codeman` socket). That field was a
persisted cache of physical reality and could drift — causing live sessions
to be wrongly marked dead ("tab shows no session found") and spawning
duplicate "Restored:" tabs.
All Codeman sessions now live on one process-wide socket (`tmux -L codeman`,
overridable via CODEMAN_TMUX_SOCKET), exposed via TmuxManager.muxSocket on
the TerminalMultiplexer interface. reconcileSessions() collapses from a
multi-socket scan (locate / re-pin / cross-socket dedup) to a single
`list-panes` query. loadSessions() strips the obsolete field from on-disk
records so it stops being written back.
Also fix two sibling bare-`tmux` call sites the unification would otherwise
leave broken (same #80 regression class — bare tmux hits the user's default
server and never finds a session on the codeman socket):
- session.ts queryTmuxWindowSize(): add `-L <socket>` (was silently falling
back to 120x40 on re-attach, losing scrollback)
- session-routes.ts send-key (Shift+Enter / Ctrl+Enter newline): route
through ctx.mux.muxSocket
SSH chooser scripts (tmux-manager.sh, tmux-chooser.sh) route every tmux call
through `tmux -L $CODEMAN_TMUX_SOCKET`, matching the TS default.

- Filter empty sessions from history API (check for conversation content)
- Add --resume fallback to new session if resume fails (prevents dead panes)
- Pass resumeSessionId through respawnPane for dead pane recovery
- Persist respawn presets and runMode to server settings (cross-device sync)
- Fix mobile touch handling for Recent Sessions dropdown (DOM API + touch CSS)
Consolidate duplicated MockSession/MockStateStore into test/mocks/,
migrate respawn tests to shared mocks, and add 58 route tests for
session, system, and respawn endpoints using Fastify app.inject().
