Names tmux reads as target syntax (`@1`, `%1`, `=eq`, a bare `~`) passed the
has-session guard by name and then joined something else in new-session -t:
another session, or a fresh shell on the foreign server. They are refused at
discovery now, and take the existing skipped note.
One stopped tmux server emptied the whole local list and left a stuck client
per scan. Each server now gets a bounded ping with stdout at /dev/null first,
because a tmux client hands dups of its stdout to the server: a stopped server
holds our pipe open after the client is dead, so a watchdog around list-panes
cannot work. The probe runs in its own process group, all three transports
keep the rows read before a failure, and a missed ping becomes a note.
The attach and the probe pass -u, so a POSIX-locale container no longer garbles
the tab or lists a non-ASCII name as underscores. A docker attach gets the same
TERM and COLORTERM an owned container's exec gets.
A missing tmux no longer reads as "session is gone", and the launch line's `$`
now reaches bash unexpanded, so the ssh attach's PATH line is expanded at the
far end, as the probe's already was.
fix-plan/write, fix-plan/read and ralph-prompt/write refuse an adopted session:
its workingDir is the neutral /tmp, so they read and wrote a predictable name
in a folder anyone can write to.
FOREIGN_MAX_SOCKETS is gone: it capped nothing, and a real cap in glob order
would never reach `default` on a box with many `codeman-*` sockets (this one
has 212). Closing an adopted tab re-reads the outside-sessions list.

The two routes are public under /api/v1, so they get an API reference section.
The overlay gets an architecture note and a CLAUDE.md rule: an adopted session
has session.remote and session.docker undefined and a neutral workingDir, so any
new code that reads workingDir as a workspace must also test isAdopted. That is
the class of bug this round fixed a dozen times.
Records a measured limit: while the view exists an owner's kill-session leaves
the window alive under it until the tab closes.
Comments that still called workingDir the foreign pane's cwd now say what is
true since the wrapper got its neutral folder. Also drops a zh-CN key that
duplicated an existing one, and updates the two structure tests pinned on the
lines this round changed.

Docker discovery now spawns dockerEngineArgv(), not the shell-quoted
buildDockerBaseArgs(): execFile passed those quotes through, so docker
--context "'default'" failed and every container behind a named context or
remote daemon read as unreachable.
The ssh probe and attach gain withRemoteTmuxPath() like every other remote tmux
call, run in an explicit sh because the guard chain is POSIX and the remote
login shell may be fish, and the probe holds a slot of the remote-ssh limiter
and execs ssh so a timeout reaches it. Notes from a remote scan are no longer
dropped, and every note now opens with its location.
The adopted branch of killSession no longer blocks the event loop on docker or
tmux, kills the in-container view by exact name, and clears the pane-exit and
reconnect state the non-owned remote branch does. An adopted wrapper reports
no injected statusline, since nothing could carry it. Key tables on the foreign
server are left alone on purpose, and the invocation now says so.

Brings the 1.33.2 based adoption feature up to master. Conflicts were
resolved by keeping master's intent and re-applying the feature on top:
both sides kept for imports, the script tag and the stylesheet blocks; the
trust-dialog guard keeps master's stopped check plus the adopted refusal;
the Ralph and image watchers keep master's remote branch plus the adopted
skip; the close confirmation keeps master's worktree option plus the
adopted wording.

`cwd` beside the fixed `workingDir` reads ambiguously on a public API surface, and
`paneCwd` says where the value comes from, like `paneExit`. Also pin the field on
the payload the browser really receives (getSessionStateWithRespawn), and give the
pane-directory text its own architecture-invariants paragraph.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
tmux reads a pane's directory from the process cwd, which is always the
resolved path, while workingDir keeps the spelling the case was created
with. For a workspace reached through a symlink every reading looked
like it was outside the workspace, so the browser sent each relative
link through the attachment route instead of the workspace routes.
Each session now resolves workingDir once in the background, bounded by
probePathKind() and a timed realpath(), and setCwd() writes a reading at
or under the resolved path back in workingDir's spelling. Until that
settles only a reading lexically inside workingDir is taken. An unknown
probe or a failed realpath leaves readings untranslated and retries
after WORKSPACE_REALPATH_RETRY_MS.
Also corrects two comments: cwd is written to state.json but never read
back, and a blank pane path is usually a pane whose program exited.
applyPaneExits() only applied the manager's directory when it returned a
value, so after a successful read a session that was split into several
panes, or was no longer on the socket, kept its stale cwd. The manager
already keeps its map across a failed or empty read, so the server now
applies its answer as given, undefined included, and setCwd() broadcasts
the clear once.
A blank #{pane_current_path} on a single-pane session (tmux could not read
the process cwd that tick) now carries the previous entry forward in
derivePaneCurrentPaths(), so only a split or unlisted session clears.
The server tests now drive the real TmuxManager with only the tmux read
faked. docs/api-reference.md documents SessionState.cwd.
A relative path printed in the terminal was resolved against the session's
workingDir, which is fixed at create time and never follows a cd. In a shell
that moved into a subdirectory or a sibling repo, the link opened the wrong
file or reported "File not found".
The pane-exit watcher's batched list-panes read already carries
#{pane_current_path}. derivePaneCurrentPaths() turns those rows into one
directory per single-pane session, TmuxManager.getPaneCurrentPath() serves it
from memory, and the server applies it on the existing paneExitsUpdated tick
as SessionState.cwd, broadcasting only on a change. No new tmux call, no new
SSE event. A failed read keeps the previous answers.
Session.setCwd() uses the paneExit scoping rule: remote and Docker sessions
never get a cwd (their local pane runs the ssh or docker exec client), nor do
direct-PTY or rediscovered sessions. The value is runtime-only.
In the browser, relativeResolutionBase() picks the live cwd when known and
workingDir otherwise. It only changes the base a relative path joins: the
result is routed as before, so a target outside the workspace still goes
through the attachment routes, and file-content/file-raw are unchanged.
The combined capture-pane and cursor query swallowed a thrown error and the
caller then ran the same capture again, so a hung tmux blocked the event loop
for two 5 s timeouts on every visible-frame capture, which serves every
GET .../terminal load. A thrown error now reaches the capture's own catch;
only output that splitFrameAndCursor cannot split falls back to the two
separate calls. The capture runs through a captureRunner() seam, like
inputRunner(), so the tests count the tmux calls each path makes.
Stage now re-reads the pane after typing (every 50 ms, up to 1 s) and
issues a receipt only for a frame with the same generation, the input
revision its own write moved, and a composer hash equal to the
message's. Codex repaints 30 to 60 ms after the keys, so the first
capture was often stale and stage refused with the text already typed.
Every refusal after typing now says the message may be in the composer
and points at the Ctrl+U recovery. A visible-frame capture reads the
screen and the caret in one tmux invocation, with the old two calls as
the fallback.
Codex draws its suggestion popups above the composer and keeps the
footer, so a staged /stat verified and submit ran /status. Stage now
refuses a leading / or ! and a last word starting with @ or $ before
typing, and stage and submit refuse a frame with popup rows just above
the composer. The pattern and characters are registry data
(composerPopupLine, composerCommandPrefixes, composerCompletionSigils),
read from the codex 0.162.0 bottom_pane sources.
Submit waits until 250 ms after the staged keys: codex turns an Enter
within 120 ms of a typed burst into a newline. POST .../input answers
409 with its seq returned while a guarded submit holds the input lease,
instead of 200 for bytes it never wrote.
Also align the attribution memo comment with the code (a verified file
whose incremental scan fails is not re-walked, since the full walk
reads a superset), and list stage as a fromUser source in CLAUDE.md.

`send-keys -l <text>` keeps parsing options after `-l`, so text starting

never typed. End option parsing with `--` at every send-keys -l site in
sendInput() and sendInputToPane(), as set-buffer already does.
Squash of PR #669. Browser terminals could be moved onto another session
by tmux's prefix keys: Ctrl+B then ), (, s or w switched the tab's tmux
client to a different session while the tab kept the original's name.
Codeman's tmux socket now keeps only Ctrl+B Ctrl+B (send-prefix) in its
prefix table, and codeman tui and scripts/tmux-manager.sh get F1 as their
way out instead of Ctrl+B d.
Merge-time fixes by the maintainer: on an empty prefix table the
unbind-key that fails no longer skips binding send-prefix; a key tmux lists
escaped (prefix C-\ shows as C-\\) compares equal, so the reset does not rerun on every create;
and reconcileSessions() reduces the table at boot when the socket has live
sessions, so sessions that survive an upgrade are covered too.

`" \nfix it\r"` still pasted a blank first line, because the leading strip
only matched `\n`. /^\s*\n/ drops everything up to the last leading line
break, mirroring the trimEnd() at the other end, and the first real line

"\nfix it\r" pasted an empty first line. Leading line breaks are now
dropped like trailing ones. Document what useMux does with a line feed,
and that a pane without bracketed paste receives each pasted line break
as CR, so a multi-line write without \r runs every line but the last
there, where the old line-stripping typed the joined text and ran nothing.

Every pane starts in TMUX_LAUNCH_CWD (/tmp) and reaches its workspace with a
cd inside the pane command, but a remote or docker pane never does that cd,
so tmux reports /tmp for it. A rediscovered record carries no remote/docker
metadata and looks local, so adopting that directory would root the session
at /tmp: hooks written into /tmp/.claude, the Files panel at /tmp, and a
respawn running claude in a directory any local account can write to.
reconcileSessions() now skips a pane whose directory is the launch directory,
in both spellings a pane can report it: the literal one and its realpath
(/private/tmp on macOS, where a process cwd comes back resolved). The set is
computed once at module load. Such a session falls back to process.cwd(),
as before this series.
Also stop trimming the list-panes output: the directory is the last field,
so a trim cut a trailing space off the last row's path; parsePaneRows()
already skips empty lines. And the comments that list what a discovered
record knows for certain now include the directory, when tmux reported a
usable one.

- cron resolvePrompt(): give the reason the rest of the cron docs give (the
submit check cannot recognise a multi-line paste; in paste mode the newlines
reach the CLI as keys) instead of the old one about writeViaMux fusing lines.
- sendInputToPane(): it types with send-keys -l and strips line breaks, so it
no longer uses "the same approach as sendInput()".
- TUI client: newlines become spaces (the docstring said stripped), and the
test name no longer cites "multi-line breaks Ink".

- sendInput's docstring said all text without `\r` is typed; that now holds
for single-line text only.
- The skill's big-input section still listed "the newline stripping" among
the hazards a workspace file avoids; it is the unconfirmed multi-line
paste now. Rewrapped, mirrored in plugins/codeman.
- The mobile composer's hand-back comment said the prompt transport strips
newlines. The hand-back writes to the terminal prompt, whose text reaches
the PTY as typed input, where a newline is a key; the behaviour (a
multi-line draft stays parked) is unchanged.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
TmuxManager.sendInput() removed every `\n` before the text reached tmux, so a
multi-line prompt sent with `useMux` (or a multi-line respawn prompt) arrived as
one line with its lines run together: `"echo A\necho B\r"` ran `echo Aecho B`.
The text half of a submit has gone in as one bracketed paste
(buildPasteTextCommands) since the Codex paste-burst fix, and inside the paste
markers Claude Code and Codex insert a pasted line break into the composer
instead of submitting. So the `\n` is now kept (`\r\n` loses only its `\r`) and
the existing paste carries the lines; the Enter stays a separate tmux call.
Multi-line text without an Enter is pasted too rather than typed with
`send-keys -l`, where every line break would reach the pane as a key.
Single-line input is unchanged.
The test-mode gate moves from the top of sendInput() into inputRunner(), as
readPaneRows() does, so a test subclass can record the commands sendInput()
would run instead of pinning the branch shapes on the source.
SubmitVerifier still compares the composer's last glyph line with the prompt
minus its newlines, so it does not reliably recognise a multi-line paste and
may not re-press an Enter that Claude Code ignored. `agent send` and the TUI
therefore keep refusing or joining multi-line input; the docs that described
the stripping now describe the paste and that limit.

reconcileSessions() adopts codeman-* sessions it finds on the socket but has
no record of (a lost or stale mux-sessions.json) as "Restored: ..." entries,
and set their workingDir to process.cwd(). Every such session then looked like
it lived wherever the server was started, and a later respawn of it cd'd
there instead of into its project.
tmux already knows the answer as #{pane_current_path}. It is appended as the
last field of PANE_LIST_FORMAT, so a directory containing the separator stays
whole, and parsePaneRows() reads it as PaneRow.currentPath. No extra tmux call:
the same list-panes read that yields the pid now yields the directory.
The path is set by whoever owns the pane, so it is admitted only if it passes
isValidPath(), the check createSession() and respawnPane() already apply to a
workingDir; otherwise, and when tmux reported none, process.cwd() stays the
fallback. A hand-split session takes the first pane tmux lists.

Claude Code draws its prompt suggestion in an empty composer, the first letter in the reverse-video cursor cell and the rest faint, so a plain capture read it as typed text and keep-warm never nudged those sessions. The keep-warm pane read now uses capture-pane -e and drops the suggestion before checking the composer.
Also from review: an off status carries no window, automation and an unreadable composer retry instead of stopping, a failed evaluation re-arms a retry, a trigger during an evaluation queues one follow-up that remove() cancels, and the cap's clock is seeded from lastSubmitAt for pre-upgrade state.
Claude Code lets a subscription's one-hour prompt cache expire after an hour idle, and the first turn back re-writes the whole conversation at the cache-write rate; nearly every gap over an hour goes cold, while the saving is concentrated in gaps of one to four hours. Codeman now sends one short keep-alive turn five minutes before the expiry Claude Code reports on its statusline, so the next real prompt still reads the conversation from cache, and stops two hours (configurable) after the last real prompt.
Codeman owns the idle policy for these sessions, as agreed in Discussion #554: a launch with keep-warm on also carries idleCompaction: false in its one --settings JSON, so Claude Code's own idle compaction cannot replace the conversation with a summary a minute before the nudge. It is decided once per launch (keep-warm on, the statusLine exporter injected, Claude Code 2.1.290 or newer, an unknown version fails closed like --name), recorded on the mux record, and picked up by any relaunch; a launch with keep-warm off is byte-identical. A session switched on after launch is kept warm best-effort and the readout says so.
Every guard lives in one pure rulebook: the opt-in (an agent-spawned session does not inherit the app default), a launch that reports cache state, a warm 1h cache with enough tokens at stake and no compaction this gap, a live pane, no usage-limit pause, no respawn, Ralph, task or waiting agent, idle, no open dialog, an empty composer and no recent keystroke. The nudge is a submit and moves lastSubmitAt, which the response viewer's conversation correlation needs; the cap counts from its own persisted lastRealPromptAt instead. Read My Mind drops the exact nudge text, and the turn's stop hook and idle prompt open pre-acknowledged so nothing alerts. The last cache report and the clock survive a restart, so the timer re-arms.
GitHub Copilot CLI (`copilot`) becomes a run mode: Run menu, welcome
screen, cron and CLI management once it is installed, tmux-backed like
the other agent CLIs, working/idle and the model read off its footer,
launch options through `copilotConfig` (model, resume, continue, the
multi-user-clamped allowAll), Custom Model Endpoints via Copilot's BYOK
variables, MCP sync of its mcp-config.json, a status probe, and the
`codeman agent` verbs (spawn waits for its composer, read returns its
last answer).
The plan-usage quota row that earlier rounds carried was split out on
review and is not part of this merge.
Merge-time commits on top: the wider COPILOT_* clamp and the zh-CN
README rows (maintainer), the Docker sign-in docs, divider rows inside
an answer kept by `agent read`, route tests for the screen-read
last-response branch, and doc drift (Past Sessions, wheelForward JSDoc,
COPILOT_/OMP_ in the env prefix lists).
Verified before merge on Copilot CLI 1.0.98: injected keystrokes,
bracketed paste and Enter reach the TUI in tmux (github/copilot-cli#4180
does not reproduce), a shell tool call completes inside tmux (#4223 does
not reproduce), and a session driven through this branch answered over
send-and-wait.

Claude Code's and Codex's selection dialogs ignore a bracketed paste, so
after the previous commit a pasted `3` + Enter confirmed the highlighted
option instead of option 3. sendInput() now types a single character with
`send-keys -l` as master did (submitsAsKeys()). One character cannot form
the burst Codex reads as a paste, so the Codex fix is unaffected.
The trailing-`;` escape moves into escapeTmuxTrailingSemicolon() and now
also covers every `send-keys -l` call in sendInput() and
sendInputToPane(); tmux 3.5a types `x;` for `send-keys -l 'x\;'`.
Docs: the @fileoverview lines and orchestrator-loop-architecture.md still
described `send-keys -l`; CLAUDE.md, architecture-invariants.md and
cron-guide.md name the single-character exception.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
sendInput() typed the text of a text+Enter pair with `send-keys -l` and
sent Enter 50 ms later. Codex detects an unmarked paste from a fast
character burst and folds an Enter inside that window into the paste as a
newline, so the prompt stays in the composer unsubmitted. Measured with
codex-cli 0.162.1 in a throwaway tmux pane: 1505 chars stuck 3/3 as
`[Pasted Content 1506 chars]`, a 98-char line stuck 1/4. SubmitVerifier
re-presses Enter for the short case, but it cannot match the long one: the
composer shows the placeholder instead of the prompt's head.
The text now goes in via set-buffer + `paste-buffer -p -d` (markers only
when the pane requested bracketed paste), followed by the separate Enter as
before. Same pane, same texts: 4/4 and 3/3 submitted. Each send gets its
own named buffer; a paste that fails (pane or server gone) deletes it,
since tmux never trims named buffers on its own.
Also escapes a trailing `;` in the text, which tmux treats as a command
separator (`send-keys -l 'x;'` typed `x`, a lone `;` typed nothing).
sendInputToPane() has no callers in src/ and is left as it was.

#609 keeps remote screen rows between the remote history and the local
frame. Those screen rows come from a separate capture-pane in the remote
command list, encoded from the default state, so the history's last row could

reset before the screen rows, as the rows above the frame already do.

A full-history load of a remote SSH session reads the scrollback from the
remote tmux in one bounded ssh round trip and splices it above the local
frame. A transport failure (ssh 255, timeout, unparseable output) starts a
30 s per-host back-off; a missing remote session is per-session only.

Conflicts resolved against #583 and #588:
- One history-depth field: #583's `historyLines` / `capturedHistoryLines`

instead of a second `capturedHistorySize`. #601's `alternateOn` /
`capturedAlternateOn` joins it, and the one display-message format string
ends `#{history_size} #{alternate_on}`.
- selectSession keeps #588's full=1 switch for panes with no scrollback, gated
off remote and Docker sessions, and #601's SHELL_LOAD_QUERY for shells.
- computeHistoryTruncationNotice names a line count when paneHistoryLines is
known (#583) and otherwise uses #601's remainder wording.
- docs: api-reference lists both historyLinesCut and paneHistoryLines; the
notice invariant keys on history_size while the shell's automatic load is
the one place alternate_on decides.

tmux before 3.2 prints no newline after `capture-pane -p` output, and
`-J` leaves the history's last row unterminated when the screen starts
inside a wrapped line. The marker row printed next is then glued onto
that row (`...first half<marker>\n31\n...`). The parser took the marker
only as a whole row, so it returned null and every load fell back to
the local capture while the screen stayed that way. Debian 11, Ubuntu
20.04 and RHEL 8 ship tmux 3.1c, 3.0a and 2.7.
The parser now takes the first `<marker>\n` wherever it ends a row (the
marker is random per read, so no row the pane holds ends with it) and
re-terminates a history that lacks its newline. A tail -c cut still
drops only the history's partial first row, now decided on the whole
output, so a cut inside the one row the marker is glued to leaves no
history instead of losing the marker. dropPartialFirstRow, no longer
called, is removed.
Docs and the findFrameInScreen JSDoc also say the splice does not place
the frame of an agent TUI mid-turn (a live region pinned to the bottom,
new rows inserted above it), which falls back to the history-over-frame
join.

Claude Code's tracker nulls recache_tokens_if_cold at a compaction or a tool-result clearing and only counts the expected rebuild at the next request, which also closes the window, so no report carried both and the old rule never fired. Stamp on the first warm null report after one that carried a value, carry it through idle re-reports and drop it at the next request; the readout now says "Context compacted at HH:MM" since a clearing opens the same window.
Also persist a changed report so a crash restores the latest one, rename the session field to statusLineExporter (statusLineTelemetry is the registry capability) and document its values, word the stake as re-cached, move the readout block above the SSE staleness heading, and drop keep-warm mentions until it lands.
The remote history and the local frame are read a round trip apart, so
two seams dropped rows at the join: rows that scrolled off the screen
during the round trip, and the top of a remote screen taller than this
pane (a shared session sized by a taller client under window-size
latest). Both are rows of the remote screen above where the local frame
begins.
The remote script now also captures the screen, right after the
history, in the same round trip. joinScrollbackAndFrame() places the
local frame among the screen rows (findFrameInScreen(): text compare
with escape sequences and trailing blanks ignored, the screen's trailing
blank rows and last content row left out, at least three rows of
overlap with two of them non-blank, highest match wins) and keeps the
screen rows above it between the history and the frame. When the frame
cannot be placed, the join is history over frame as before. The read's
buffer slack grows to 1 MiB, since the screen is outside the tail -c
bound.
Left: the history and screen are two tmux commands, so a row that
scrolls between them (milliseconds) is lost, and a screen that repeats
a whole block can place the frame at the higher copy, losing the rows
between the copies.

Review follow-ups for loading a shell from tmux's rendered history.
tmux adds no history while a pane is in the alternate screen, and a
nested tmux client (remote SSH and Docker cases, or tmux run by hand)
holds its pane there, so a full capture of it is one screen. The
display-message query that reads #{history_size} now also reads
#{alternate_on} (PaneCaptureOptions.capturedAlternateOn), and a request
carrying `alt=recording` (only SHELL_LOAD_QUERY sends it) is answered
the old way on such a pane: the visible frame over the tailed byte
recording. Agents, scroll pulls and Load full history are unchanged.
alternate_on cannot tell a nested tmux from vim or less, so a local
shell with one of those open takes the same fallback while it is open.
A full capture without `lines=` was reported as a 'tail' cut whenever
the pane held more than the configured ceiling (possible on tmux before
3.7), offering a Load full history that could never return more. The
cut is now reported only for a client bound below the ceiling.
The response carries `historyLinesCut` when that bound left lines in
tmux, and the banner then says earlier output may be retained instead
of naming the bytes a later tail cut, which undercount what tmux holds.
A bounded grid tile's shell load sends its own `lines=` (via
SHELL_LOAD_BASE_QUERY). CLAUDE.md, docs/architecture-invariants.md and
docs/api-reference.md describe the shell load, the cut report and the
fallback.
