test/workflow-run-watcher.test.ts pinned its fixture's newest activity at
2026-06-14T20:06:40Z and then asked getRecentRunSummaries(100000) to return
it. That argument is MINUTES, so the window is 69.4 days: the assertion
expired at 2026-08-23T06:46:40Z and the file has failed on every branch
since, on a suite nobody had touched. The last green CI run finished at
06:47:43Z, about a minute inside the boundary, which is why it landed as a
surprise rather than a bisectable regression.
The fixture epochs now hang off a RUN_ANCHOR of Date.now() - 601s with every
offset preserved verbatim, so the parsed durations, the ordering and the
live-vs-done discriminators are all unchanged, and the recency filter is
still the thing under test. It just cannot rot again.
scripts/tmux-chooser.sh is deleted. codeman tui replaces it and does the
job better: sc numbered its entries globally but only accepted a single
[1-9] keypress, so sessions 10+ were listed and unselectable, and it
inferred nothing about what an agent was doing. The tui carries the
server's real states, answers permission dialogs, and leaves an attach
with one key.
install.sh no longer creates the tmux-chooser symlink or the sc alias.
It now sweeps both up instead, on update AND uninstall, so an update
cannot leave a symlink pointing at a script this version stopped
shipping. The alias removal is marker-owned: it matches the exact line
the installer wrote, so someone's own 'alias sc=' for another tool is
never touched, and it rewrites through 'cat >' so the profile keeps its
mode and ownership. Verified against three profile shapes.
BREAKING CHANGE: the 'sc' command and the 'tmux-chooser' symlink are
gone. Use 'codeman tui' (and 'codeman tui --list' / 'codeman tui <n>').
codeman tui supersedes the sc bash chooser: it reaches sessions 10+,
carries the server's real states instead of a static list, and leaves an
attach with one key. Every place that told a user to run sc now names the
tui equivalent, including the two wiki pages and install.sh's next-steps
banner. Both wiki pages also carried the wrong detach chord (Ctrl+A D;
the socket's prefix is C-b), which the tui makes moot.
Source comments that explained themselves as "the sc -l replacement" now
just say what they do. docs/tui-plan.md and CHANGELOG.md are historical
records and keep their references.
CLAUDE.md gained "any new `tmux -L` caller through `resolveTmuxSocketName()`"
but architecture-invariants.md, which that bullet points at for the
mechanism, still described only the dataPath() half. Say why the rule
exists there too: the TUI is the first non-server process to shell out
to tmux.
The sc chooser runs a plain `tmux attach-session` and binds nothing, so
F1 does not detach from it; only `codeman tui`'s attach claims that key,
and only for its own duration. The line it replaced was wrong too (the
socket's prefix is C-b, not C-a), so name the real chord and say which
command gives you the single key instead.
The guide and the README both said to detach with `Ctrl+B D`. Beta testing
proved that wrong twice over: tmux binds lowercase `d` to `detach-client` and
capital `D` to `choose-client`, and even the correct letter fails for anyone who
keeps Ctrl held, because that sends `Ctrl+D`, which tmux leaves unbound. A
tester followed the documented instruction, stayed attached, and exited the
agent to escape.
Both now say `F1`, and the attach section describes what actually happens: the
session strip across the top of the pane, `Alt+1`..`Alt+9` switching without
returning to the dashboard, and `r` to resume a session whose pane has died.
Also corrected: `1-9` switches rather than jump-attaches, `x` confirms with `y`
rather than a typed name, and a new session opens straight into its pane.
`docs/tui-plan.md` is deliberately untouched — it is the design record of what
was planned, not a description of what shipped.
The loose end from 777f974, now explained. Sessions came back from a detach on
`window-size latest` instead of `manual`, and the restore primitive round-tripped
correctly in isolation, so the corruption had to be upstream of it. It was: the
snapshot was taken from state this code had already broken.
`bindSwitchKey` passed a bare `;` between the two commands it wanted in one
binding. That is a command separator to tmux's OWN parser, not an argument: it
ended the `bind-key` and executed what followed immediately. So the binding kept
only `switch-client`, and `set-window-option ... window-size latest` RAN against
every switchable session at attach time — before the sizing snapshot was taken.
Every session was therefore snapshotted as `latest` and faithfully restored to
`latest`.
Proven against real tmux both ways before fixing: a bare `;` leaves the session
on `latest` and stores a one-command binding, while `\;` leaves it `manual` and
stores both commands.
Verified end to end: 7 sessions manual before, 1 latest + 6 manual during the
attach (the attached one follows the terminal, the rest are pre-sized), no dot
padding on a switch, and all 7 back to 120x40 manual after the detach.
This also means the "follow the terminal after switching" half of 777f974 never
actually worked — it was never in the binding.
The overview showed the same session twice, one frame above another, after
switching sessions (reported from the beta with a screenshot).
Claude repaints by ABSOLUTE CURSOR POSITIONING, not by clearing: a 198KB pane
tail carries 1142 `CSI r;c H` and exactly one `CSI 2J`. The replay honoured the
COLUMN of those sequences and ignored the ROW, so a repaint could never
overwrite what came before and was appended instead. That same tail replayed as
FIFTY stacked copies of one frame. The preview shows the last N lines, so on a
short terminal you saw the newest frame by luck and on a tall one you saw the
end of the previous frame above it.
A cursor HOME now starts the buffer over. That is not a heuristic but the
line-based equivalent of what a home means: a full-screen app announcing it is
repainting from the top, with everything on screen about to be overwritten in
place. Only row 1 column 1 counts — any other address is a write position
inside the frame being painted, and resetting on those would erase live
content.
Measured on the real tail that produced the screenshot: 198599 bytes and 50
copies of the welcome frame collapse to 40 lines carrying exactly one.
The old test pinned the append behaviour, including a spurious leading empty
line that the initial CUP produced; both are gone.
The bar now reads "alt+1-9 switch · F1 back to the codeman dashboard", so the
switch keys are discoverable instead of secret. Shown only when those keys were
actually claimed, the same rule the way-out key follows: a bar naming a key
that does nothing is the bug this series started with.
THE DOT GRID. Switching landed in a pane occupying part of the terminal with
tmux's dot fill everywhere else. It was never a size mismatch — the window was
already the right size. `window-size latest` only resizes a window while a
client is ON it, and the sessions behind the tab strip have none until you
switch, so the resize happened AT the switch: tmux painted the newly-available
area with dots and an idle claude had no reason to redraw into it. Every
switchable session is now pre-sized to the attaching terminal, which moves that
repaint to attach time while the user is still looking at the first session,
and the switch binding restores `window-size latest` on arrival so a mid-attach
terminal resize still follows. Measured: 14 consecutive switches across 7
sessions, zero dot-padded rows, against 1-in-6 before.
⚠️ Known loose end, deliberately not papered over: after a detach the window
SIZE is restored exactly but the window-size MODE can come back as `latest`
rather than `manual`. The restore primitive round-trips correctly in isolation
(manual -> presize -> latest -> restore = manual) and no call site in the TUI
or the server sets `latest` afterwards, so the cause is not yet identified. The
practical effect is nil: the remaining client keeps the window at its own size
and Codeman re-pins `manual` on the browser's next resize.
Switching with Alt+N landed in a pane that filled part of the terminal with
tmux padding the rest as a dot grid — reported from the beta with a screenshot
showing the pane in the left half and dots everywhere else.
Codeman pins every window `window-size manual` at the BROWSER's size
(tmux-manager.ts), so no attaching client can resize it. The attach already
lifted that for the session it opened, which is why a plain attach looked
right; `switch-client` then moved the user into a session that had never been
lifted, and the old pin reasserted itself. `window-size latest` now goes on
every session the strip can reach, alongside the bar those sessions already
get, and each one's original sizing is snapshotted and restored on detach.
Verified by round-tripping a session pinned at 120x40 manual: latest 190x49
while attached, back to 120x40 manual after, with no dot rows at either step
and the bar intact at full width after a switch.
The renderer's own FOOTER_KEYS table still said 'jump'. It is only reached when
the app layer supplies no footerKeys, so nothing visible was wrong, but a
fallback that contradicts the live footer is exactly the kind of drift that
turns into a bug report later.
Four faults, all reported at once, and three of them were mine from the last
two commits.
THE HINT VANISHED. Two independent causes. First, a leaked F1 binding: an
attach whose TUI was killed leaves `F1 -> detach-client` in tmux's root table,
and the claim treated "already bound" as someone else's key, so every later
attach fell back to advertising the tmux chord — the bar stopped saying F1
while F1 still worked. A key already bound to `detach-client` now counts as
ours. Second, width: tmux truncates a status line that overflows and drops the
RIGHT-aligned segment, which is the hint. The strip now gets a budget measured
from the terminal's width minus the hint, and it drops tabs from the far end
until it fits. ⚠️ Measured on VISIBLE columns, not format bytes: `#[reverse]`
costs zero columns, and counting it made a strip that "fitted" still truncate
the hint at 80, 100, 120 and 176 columns on a real terminal.
ALT+N DID NOT SWITCH. On the dashboard, a bare digit meant jump AND ATTACH, and
a terminal sends Alt+N as ESC then N: when those land in separate reads —
routine over SSH — the chord decodes as Escape plus a bare digit, so "switch to
tab 2" threw the user into tab 2's pane. A digit now SELECTS, matching what
Alt+N means in the web UI; Enter is how you go in. Inside a pane the keys never
reached the TUI at all, since tmux owns the terminal, so the attach now binds
Alt+1..9 in tmux's root table to `switch-client` — the strip is usable rather
than decorative. ⚠️ The bar is applied to every session the strip can reach,
each highlighting its own tab: with it on the attached session only, switching
landed the user in a pane with no strip and no way out on screen.
⚠️ The leaked-state sweep was missing `status-position`, so it removed the
marker and left the position behind — and with no marker the leftover no longer
matched, making it permanently unsweepable. Found by diffing every session's
options after a detach.
Attaching made every other session disappear: the dashboard is gone, tmux owns
the terminal, and there is nothing left saying what else is running. The attach
bar now carries the session strip, numbered exactly as the dashboard numbers
them, with the session you are in inverted, and it sits at the TOP of the pane
where the web UI keeps its tabs.
The strip is a WINDOW around the active tab, not the whole list, with ellipses
marking each end that is actually cut. The bar is one line shared with the way
out, and that hint is the only instruction a user gets while tmux has the
terminal, so it must never be crowded off; a test drives 20 long-named sessions
through the bar and asserts it survives.
⚠️ The strip is a snapshot taken at attach time and never refreshed. The TUI is
blocked in `spawnSync` for the whole attach so there is no loop to update from,
and tmux's own format language cannot map a `codeman-<hex>` session name back
to a label a human recognises. Slightly stale beats absent.
The way out moves from F12 to F1, which sits beside Esc where a hand backing
out already goes. Verified against BOTH encodings a terminal sends for it:
xterm's SS3 (ESC O P) and PuTTY's default (ESC [ 1 1 ~).
`status-position` joins the snapshot, so a session that had its bar at the
bottom gets it back there on detach along with everything else.
Three separate "why are there boxes" reports, and I fixed them one glyph at a
time instead of as a class, so the next one was always waiting. Grouping the
tester's terminal by unicode block made the rule obvious:
RENDERS Latin-1 (·), Box Drawing (─ │), Block Elements (█ ▛ ▐),
Geometric Shapes (○ ▶), General Punctuation (…), Arrows
TOFU Miscellaneous Technical (⏎ U+23CE, ⏵ U+23F5), the sparse end
of Dingbats (❯ U+276F)
That is an ordinary font, not a broken one, so it is the profile to design
against. The working spinner moves off Dingbats and Math Operators onto
quadrant blocks (▖▘▝▗) — the same block as the `▛█▐` art claude itself draws,
which that font renders fine — and the blocked marker moves off `⚠`
(Misc Symbols, emoji presentation on many terminals) onto `▲`, the block that
already gives us `▶` and `○`.
The preview fold gains claude's own spinner dingbats (✢ ✳ ∗ ✻ ✽ ✴ → `*`) and
`⚠` → `!`. Its animated status line is exactly where a reader looks, so tofu
there is the most visible kind there is.
A test now enforces this as a CLASS: no glyph in the unicode set may come from
Misc Technical, Misc Symbols or Dingbats, with U+2714 the single documented
exception because it was observed rendering on the very font that failed the
others. Verified by scanning a live frame driven with the tester's exact
environment: zero glyphs from any of the three blocks.
Killing demanded the session's NAME typed out in full. That is the right
ceremony for dropping a production database and the wrong one for closing a
pane you are looking at; the beta tester's verdict was "thats stupid, just make
me type Y to confirm". `x` then `y` is already two deliberate keystrokes on a
row the user selected, and the conversation lives in its transcript, which a
kill does not touch.
Everything that is not `y` CANCELS rather than being ignored, so a stray key
closes the dialog instead of leaving a destructive prompt armed and waiting for
whatever gets typed next. Enter cancels too: it is the key most likely to be
hit by reflex, and this is the one dialog that destroys something.
⚠️ Found while verifying the new dialog: it did not name the session. The label
was computed as `row.session.name ?? id.slice(0, 8)`, and `??` falls back only
on null or undefined, so every session the server left with an EMPTY name — all
of them, until the TUI started naming its own — sailed through and the box read
"Kill ?". A destructive prompt that cannot say what it will destroy is worse
than no prompt, and it is now a single keystroke. The caller passes the same
label the LIST shows, so the dialog names the row in front of the user.
The typed-name machinery goes with it: TuiConfirmState.typed, setConfirmInput(),
confirmAccepts() and the 'typing'/'reject' steps are all removed rather than
left as unreachable branches.
Two reports from the same beta screenshot.
Starting a session left the user on the dashboard next to the row they had just
asked for, which reads as the create having silently failed. Starting a session
is a request to WORK in it, so the terminal now goes there as soon as the pane
exists, and the CLI booting is worth watching. If the pane is slow the notice
says so and the row is left selected, exactly as the resume path does.
The footer's `↵` was drawing as an empty box: `⏎` (U+23CE) has poor font
coverage, on the same terminal that renders `·`, `─`, `│`, `○`, `▶` and `✔`
perfectly. It is now U+21B5, from the Arrows block every monospace font ships.
`✋` (U+270B) was worse than a coverage problem: it is East Asian WIDE, so the
renderer, which addresses cells by column, was reserving two cells for it. The
golden frames had the age column shifted a space left to match, which is how
long that had been wrong. It is now `!`, and the frames align correctly.
A test walks the whole unicode glyph set and fails on any entry wider than one
cell, so a glyph that shifts the layout cannot be added again. The comment on
the table spells out both bars a glyph has to clear, because the tier check
answers neither: it asks whether the LOCALE is UTF-8, which says nothing about
whether a font has the glyph or how wide it draws.
Alt+1..9 switches to that session, and `[` / `]` / Tab step through them, so the
muscle memory from the web UI carries over.
Alt+N SELECTS rather than attaches, which is what the web UI's Alt+N does:
switching which tab you look at is cheap and reversible, and the terminal
equivalent is moving the selection and its preview, not handing the whole
terminal to a pane. Bare 1-9 keeps its documented jump-and-attach meaning.
Two of the web UI's chords cannot cross into a terminal, so the nearest
transmittable keys carry them instead:
Alt+[ / Alt+] ESC+[ IS the CSI introducer every arrow key arrives on, and
ESC+] is OSC, so neither chord is distinguishable from a
sequence. Bare `[` and `]` do the job.
Ctrl+Tab a terminal cannot report the Ctrl, so plain Tab carries it.
⚠️ The parser now decodes ESC + a printable character in ONE read as an Alt
chord, and the app replays every chord it does not claim as `escape` then that
character. That fallback is load-bearing, not tidiness: a real Esc landing in
the same read as the next keystroke is byte-identical to a chord, and without
the replay "Esc then q" typed quickly decoded as Alt+Q, matched nothing and was
swallowed. The e2e suite caught exactly that as the dashboard refusing to quit.
A lone Esc is still held and flushed on the caller's timer, which is what keeps
the two separable at all.
A beta tester photographed claude's `❯` prompt and its `⏵⏵` bypass-permissions
marker rendering as empty boxes in the preview pane. Their font has no coverage
for those codepoints while drawing `·`, `─`, `│` and `▶` perfectly.
The glyph TIER cannot help here. It answers "can this terminal do Unicode at
all", which is a locale question, and it correctly says yes for exactly the
terminals this affects. Coverage is per-glyph and undetectable from inside the
process, so the handful of rare glyphs CLIs use as chrome are folded to the
ASCII arrows they already look like, and everything a plain font does render is
left alone.
Scoped tightly: the preview only, never the TUI's own chrome, and skipped
entirely at the `nerd` tier where the user has declared a font that can draw
anything. The table is short and every entry was seen as tofu in a real
terminal rather than guessed at. The fold is length-preserving, so the preview
pane's column arithmetic is unaffected.
Refusing the attach stopped the freeze but told the user to throw the session
away (`x` to close, `n` for new), which loses the conversation. tmux's own
dead-pane screen already says what to do instead: `claude --resume "<name>"`.
The Error card now offers `r` when the row can actually be resumed (claude,
with a conversation id and a working directory), and the footer says so. One
press resumes into a fresh pane and attaches to it, so a dead end becomes
recovery.
⚠️ Three things keep this from becoming the resume runaway that once spawned 35
sessions in 40 seconds. The offer holds a session ID, not a row, and is
re-resolved from the model when the key is pressed: a row captured when the
card opened is stale by then. It disarms BEFORE anything async, so a second `r`
cannot start a second resume. And it routes through resumeSelected(), which
owns the `resuming` flag and ends in attachToSession() rather than the group
dispatch.
⚠️ The `r` branch has to run BEFORE the generic dismiss, because a message
overlay is dismissed by ANY key: without that ordering the offer is consumed as
"some key was pressed" and the card merely closes. `help` keeps the any-key
behaviour, so the two modes no longer share a case.
Verified end to end against a genuinely dead claude pane: card, footer, one
press, one new session, and F12 back to the dashboard.
Three beta rounds died on tmux's native way out, and the last one died on the
instruction rather than the mechanism: "press Ctrl+B, release Ctrl, then d" is,
in the tester's words, very unclear, and holding the modifier through both keys
silently does nothing.
So the way out stops being a chord. The attach claims F12 in tmux's prefix-less
`root` table for its own duration, and the bar reads "press F12 to get back to
the codeman dashboard" — one keystroke, nothing to hold, nothing to release,
no order to get right. F12 because stock tmux ships an empty root table apart
from mouse bindings, and none of the CLIs that run in these panes want the key.
⚠️ The bar names the one key ONLY when the claim succeeded, and falls back to
the chord wording otherwise. A bar advertising a key that does nothing is the
bug this whole series started with, and it must not come back in a new costume.
Same claim rules as the prefix alias: taken only when tmux reports the key
unbound, given back only while it still means `detach-client`.
The chord and the held-Ctrl alias both keep working; they are simply no longer
what the user is told to press.
Reported three times as "Ctrl+B and d is still not working", on a build whose
bar already named the right key. Measured against a live pane: of the three
ways a person types this, only one worked.
Ctrl+B, release Ctrl, then d detaches
Ctrl+B then Ctrl+D (held) nothing happens
Ctrl+B then Shift+D nothing happens
Holding Ctrl through both keys sends 0x02 then 0x04, and tmux ships `C-d`
unbound in the prefix table, so the keystroke is swallowed in silence and the
attach looks frozen. That is not a user error worth documenting around: holding
the modifier is how most people type a two-key chord.
The attach now claims the held-Ctrl form of whatever key detaches (`d` → `C-d`)
for its own duration and gives it back on restore, and the bar advertises it
only once the claim succeeded, so it can never name a key that does nothing.
⚠️ The key is claimed ONLY when tmux reports it unbound, and released only
while it still means `detach-client`, so a binding of the user's own is never
shadowed or removed. The alias is deliberately excluded from the leaked-state
sweep: key tables are server-global, so the sweep cannot tell a leak from a
second TUI's live claim, and a stray `C-d`→detach is harmless either way.
Ruled out along the way, with evidence rather than assumption: the encoding.
tmux negotiates no extended-key mode upstream on attach (no kitty CSI-u, no
modifyOtherKeys, no DECSET 2017), so Ctrl+B does arrive as a plain 0x02 even
from a Claude pane, which has its own keyboard protocol.
Two more from the same beta round, both reported as "basic things are broken".
Attaching to a DEAD pane trapped the user. Codeman sets `remain-on-exit on`, so
a session whose agent has exited does not disappear: the row looks ordinary,
the server still reports it idle, and Enter handed the terminal to a pane that
reads no input. With the detach chord also wrong at the time, that was a hard
freeze with no way out. Enter now probes `#{pane_dead}` first and refuses with
an Error card naming the session and what to do instead. The probe fails OPEN,
so it can never block an attach to a live pane. ⚠️ It also has to paint: the
keypress that reaches attachToSession() has already painted by the time an
awaited probe resolves, so message() alone left the refusal invisible and Enter
looked inert, which is the bug it was added to fix.
A session started from the TUI came out unnamed, because startSession() sent no
sessionName and rowLabel() then fell back to the transcript's first line. A
brand-new session has no prompt to be named after, so the list showed a
perfectly healthy session called "Login interrupted" — the CLI's startup
output, reading like a failure report. Sessions the TUI starts are now named
`w<n>-<case>` like the web UI's, and rowLabel() prefers the case directory over
a scraped prompt for any row with a mux name, since a LIVE pane is identified
by where it runs while a history row genuinely is its prompt.
restore() runs after spawnSync returns, which covers detaching and the agent
exiting inside the pane, but not the terminal dying while attached. Closing the
window or dropping the SSH kills the TUI where it stands, and the bar it
installed stays pinned on the session: the next attach wears a stale bar naming
a different session, and the pane is a row shorter for good. Seen on the beta,
where the tester closed the window instead of detaching.
One sweep at startup, fire-and-forget so it can neither delay the first frame
nor fail a start. Only a bar carrying our own marker is touched, and the marker
is now the single source of the bar's own wording so the two cannot drift; a
user's hand-written status bar on the same session is left exactly as it is.
The session goes back to `status off`, which is how Codeman creates every pane
it owns and the only state this bar is ever applied over.
Two things the attach status bar got wrong, both found in a beta test.
The bar read `Ctrl+B D`. tmux key tables are case-sensitive: lowercase `d` is
`detach-client`, capital `D` is `choose-client`. Pressing what the bar said
opened a client chooser and left the tester attached, with the way out on
screen and inert. The key is now READ from `list-keys -T prefix` the same way
the prefix already was, rather than hardcoded, so a rebound tmux is followed
too and the label cannot drift from the binding again. It never goes through
formatPrefixKey(), which uppercases.
The bar also rendered as a full-width bright green slab. Only `status-format[0]`
was styled, so tmux's stock `status-style` (`bg=green,fg=black`) stayed
underneath it and won; `#[reverse]` on top could not undo it. `status-style` is
now set explicitly to `bg=default,fg=default` and snapshotted/restored with the
rest, so the bar sits on the terminal's own background and reads as a hint
line.
Tests pin both: that the chord ends in lowercase `d` and never ` D`, that a
rebound key prints verbatim, that `status-style` is part of the banner, and
that parseDetachKey() picks `d` out of verbatim tmux 3.4 `list-keys` output
while ignoring `detach-client -a`/`-P`, which act on other clients.
Three things the first beta test surfaced.
1. Attaching from a terminal of a different shape showed the pane clipped to the
browser's size, with tmux's dot padding filling the rest. Codeman pins every
window it owns to `window-size manual` at whatever the web client reports
(tmux-manager.ts), so no attaching client can resize it. The handoff now
brackets the attach with `window-size latest` and restores the snapshot on
detach. `latest`, rather than a one-off resize to our own size, is also what
lets a terminal resized MID-attach follow along: tmux recomputes on every
SIGWINCH while the TUI is blocked in spawnSync and cannot.
2. Nothing on screen said how to get back out, because Codeman keeps the status
bar off on its panes (the web UI carries that information around the terminal
instead). The tester exited the agent looking for the exit, leaving a dead
pane. An attach now wears a `status-format[0]` bar reading "<prefix> D
detach, back to the codeman dashboard", with the prefix READ from tmux rather
than assumed, and the session's options are put back exactly as they were on
detach. One option, not status-left/status-right, so tmux draws no window
list beside it; `reverse` so it inherits the terminal's own theme. Restoring
an array option unsets the BASE name, since dropping the `[0]` index leaves
an empty array, which renders as a blank bar on a session that had one. The
help overlay names the chord, and the dashboard confirms the detach.
3. Enter on a RECENT row said resuming was not wired up. It now creates a
session carrying that conversation (`resumeSessionId` plus `/interactive`,
the path the web UI's Resume Conversation list already uses), in the
directory it ran in and under its old name, then attaches to it.
The attach mechanics deliberately sit in a method the group dispatch cannot
reach, plus a re-entrancy flag: routing resume back through the Enter handler
re-dispatched on "this row is RECENT" and spawned one session per pass, 35 in
about 40 seconds on the beta before it was killed. test/tui/tui-e2e.test.ts
pins one press to one session with a pane that never appears, which is
exactly the case that looped.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Both of the dashboard's periodic reads hit endpoints that are far more
expensive than their cadence assumed, and the cost lands on the SERVER's
event loop, so it is paid by every browser client too.
`GET /api/sessions/unified` is ~550ms against 11 live sessions: it scans
every Claude transcript plus the lifecycle log, uncached, and republishes
the search index. `scheduleRefresh()` was a 250ms trailing debounce with no
floor, and a queued refresh re-ran the instant the previous one returned
(by recursing, which also chained one pending promise per iteration), so a
stream of events paced the refetches at the endpoint's own latency: with
`session:updated` broadcast per session per 500ms while anything is
working, the scans ran back to back. `resyncDelayMs()` now keeps ambient
refetches 3s apart, measured start-to-start. The user's own actions call
`refresh()` directly and are unaffected, so what this paces is only
"notice what changed elsewhere".
`GET /api/sessions/:id/terminal` is ~80-100ms: two `execSync` tmux calls,
then the whole byte buffer normalized before the tail is taken. It was
polled every second for as long as a live row was selected. It now backs
off 1s, 2s, 4s, 5s while consecutive reads change nothing, and resets to 1s
on any change, when the selection moves, when this dashboard sends input or
answers a dialog, and on return from an attach. A pane that is printing is
still read every second; a pane at its composer is not.
The poll also kept running in three places it had nothing to draw for: the
whole time the user was attached in tmux (an attach can last hours), and
behind the message overlays that an async action opens (answered, killed,
started), which are not keystroke-driven and so never reached the
`afterInput()` path that stops it. `setInterval` becomes a chained
`setTimeout`, since the delay now varies.
Measured against the live server, same idle row selected, 25s window:
22 tail reads before, 5 after. With a working pane selected it stays at 22,
which is the intended cadence for a pane whose output you are watching.

`TuiModelStore.confirmSatisfied()` and `approvalFor()` had no caller
outside their own tests. The first one mattered: it answered "does the
typed text authorize this kill?" with an exact name match, while the rule
actually consulted (`confirmAccepts()` in tui-app) also accepts the
8-character id prefix a mux name carries. Two divergent answers to one
question, the stricter one unreachable and waiting to be picked up by
mistake. knip cannot see class members, so the dead-code sweep never
flagged either.
The tests they existed for now assert observable state instead, and the
approvals one got stronger on the way: it checks that a session id coming
back does not inherit the dead session's dialog, which is the invariant
`removeSession()` is actually keeping.

`TuiSessionRow` declared `lastSubmitAt`/`inputTokens`/`outputTokens`,
`stateSince()` ordered the WORKING group by the first of them and
`renderRowLines()` painted the other two, but nothing ever filled any of
them in: the unified list carries none, and the `session:updated` payload
that does was discarded (an event only schedules a refetch).
So a running turn was dated by its SESSION's creation instead. Measured
against the live server before the fix: w65 (created 21h ago, turn started
one minute earlier) outranked w67 (created 15 minutes ago, turn started
five minutes earlier), the reverse of the rule docs/tui.md states, and the
elapsed column read `21h` for a turn a minute old. The token column was
unreachable code for the same reason.
`fetchLiveSessionMetrics()` reads the three fields from `GET /api/sessions`
and `applyLiveMetrics()` folds them onto the rows. That route answers from
the server's cached LIGHT state (no terminal buffers): 10-20ms measured,
against the ~550ms the unified list in the same `Promise.all` already
costs, so it is cheap enough to ride every refresh. It is best-effort like
the approvals and tmux reads beside it, because losing the anchor is
better than losing the list.
A ZERO is treated as unknown rather than merged: `stateSince()` reads
`lastSubmitAt ?? createdAt` and 0 is not nullish, so a merged 0 would date
every never-submitted session to the epoch.
The snapshot path gets the same merge, or `codeman tui --list` would number
the WORKING group differently from the dashboard that `codeman tui <n>`
indexes into.
Verified live: working rows now show 28m/8m (turn age, tokens 280.5k/65.2k)
where they showed 21h/34m and no tokens. The e2e assertion fails on master's
wiring with `[*] 10m` against a session that pressed Enter one minute ago.

The data-dir half was already spelled out; the socket half only lived in
a function docstring, and the TUI is the first code that shells out to
`tmux -L` from a process that is not the server.

The inventory test predates the `tui` command, so a rename or an
accidental removal would have gone unnoticed: it now asserts the command,
its `-l`/`--list` flag and its optional position operand.
The digest and search-result lines joined their halves with an em-dash,
which the repo's own convention rules out, so both now use the middle dot
the surrounding lines already use. The one em-dash left in `src/tui/` is
load-bearing: `search-service.ts` builds a session snippet with it, and
the pattern that strips the repeated label has to match it.
Also moves `buildSearchEntries`'s doc comment back onto
`buildSearchEntries`; it had ended up stacked above a helper.

`mark()` had no callers (knip's only finding on this branch), and the
renderer's fallback help list advertised `r` resume, which is deferred
with the rest of phase 3: a help screen naming a verb the build does not
implement is worse than no help.

The user guide covers what the dashboard is (and is not), the two
non-interactive fast paths, the four groups and their ordering, the full
keymap, what answering an approval does server-side, and the SSH/narrow
and degraded cases. The example frame is a real 100x30 capture against
the E2E fake server, not a drawing.

A server that comes up mid-run was upgrading the header's hostname and
version but not its chip, which then stayed blank until the next telemetry
event. Also swaps a typographic apostrophe out of a preview error, which is
not renderable on the ASCII glyph tier.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Two small honesty fixes at the edges: a server that goes down leaves the
dashboard holding prompts nothing can classify any more and whose answer
route is unreachable, so degraded mode clears them; and a resize can cross
the narrow breakpoint, where there is no preview pane to poll for.

Measured against a live Claude pane: an Ink TUI paints by ROW and emits
almost no newlines, so dropping cursor-position sequences collapsed a whole
screen into one unreadable line, and a tail cut mid-sequence printed the
remains of it (";1H") as text. Now a jump to column 1 starts a display line,
a jump inside a row moves the write position (capped, since a stream may
address a column no terminal has), and a severed CSI head is dropped before
parsing.
The preview is readable against a real session as a result: tool calls, the
working line and the composer all land where they belong.
Also drop the repeated session name from a search row, whose snippet opens
with the name the row already shows in its first column.

The fake API server grows the routes the dashboard now calls (terminal tail,
input, approvals answer, search, away digest, plan usage on status), and the
new cases assert on what the server RECEIVED rather than on the frame: the
prompt arrives as one line ending in a carriage return, and the answers as
the exact action and option digit.
Also covered: the tail refreshing in place, the search overlay selecting a
live session, the digest rendering, one bell for an item announced twice,
and the 409 path reported as "no longer on screen".
The plan-usage chip is punctuated with the glyph tier's separator, so an
ASCII terminal no longer gets a stray middle dot in the header.

The dashboard stops being read-only. The selected session's tail is polled
once a second while the plain list has focus and the layout is wide, and an
unchanged tail never reaches the model, so a quiet session costs no repaint.
A row with no live buffer says so instead of polling forever.
Keys: y/n and the parsed digits answer the selected session's dialog through
`POST /api/approvals/:id/answer` (never a blind keystroke: that route
re-captures the pane and 409s when the dialog has moved on, which the TUI
reports as "no longer on screen"); `p` opens a one-line composer aimed at
the selected session; `/` searches with a 250ms debounce and Enter switches
to a live session result; `g` shows the away digest. A new prompt rings the
bell exactly once, tracked by item id so a repaint or a refetch cannot
stutter, and the plan-usage chip rides `GET /api/status` plus its telemetry
event.

The preview pane now leads with the pending dialog when the selected session
has one: the question, the options with their digits, and the keys that
answer them, red for a dialog and yellow for a waiting prompt. The card is
capped at half the pane, because the tail is why the pane exists.
Around it: a header badge counting prompts that need a human, a preview
title that sacrifices the path rather than the state word, the footer
becoming the composer line while one is open (with the cell the terminal
cursor belongs in, so it can be shown there and hidden everywhere else), and
the search and digest panels as overlays with a stable width.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The store gains the three overlays phase 2 needs, each taking the keyboard
when it is set and all of them cleared together by closeOverlay(), plus the
pure flattening of `GET /api/search`'s typed groups into rows a cursor can
move over: headers are chrome, and only a session that is on the list counts
as selectable, since a history hit has no row to move the cursor to.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Three small pure modules the phase-2 verbs are built on:
- tui-composer: the single-line editor behind `p` and `/`, holding text as
code points so a cursor can never split a surrogate pair, with the scroll
window derived from the width rather than remembered.
- tui-approvals: what an approvals-inbox item's card says, which keys are
live for it (a digit answers only when the server parsed that option, and
an idle prompt answers to none of them), and which ids the bell has not
rung for yet.
- tui-digest: the away digest as compact lines, counts first and one line
per entry, with a capped tail per section.

Spawns the real command in a pseudo-terminal against a fake API server
(canned status/unified/approvals plus an SSE stream the test pushes
into), which is the only way to cover raw-mode key decoding, frames
reaching a terminal, SSE-driven refresh and the exit sequence that has to
restore the user's screen.
Two details the assertions depend on: frames are addressed absolutely
rather than newline-separated, so the parser takes the last COMPLETE
frame (the pty delivers one in several chunks, and reading a half-written
frame would be racy), and it reads the sidebar column only, or a name
echoed in the preview pane could answer for a row.
The child gets its own data dir and a tmux socket name nothing runs on,
so nothing here can see or touch the machine's real sessions.

`codeman tui` opens the dashboard, `codeman tui --list` prints the
numbered list and exits (the `sc -l` replacement, plain when piped) and
`codeman tui <n>` attaches straight to a row (the `sc 2` replacement).
Both fast paths short-circuit before any screen setup, and both refuse
the numbers path without a terminal instead of half-opening a UI.
Bare `codeman` still prints help: the web UI stays the primary surface.
The TUI module is imported lazily so the other commands do not pay for it
at startup.

The IO half of src/tui: it owns the terminal, the timers, stdin and the
tmux handoff, and every decision it makes that is a function of its
inputs is an exported pure helper with unit tests (attach planning, the
typed kill confirmation, keymap selection, the repaint test, degraded
rows).
What it does: live session list over the unified API with SSE-driven
resync (debounced, with a 2s poll fallback the client asks for), cursor
and 1-9 navigation, attach and return, kill behind a typed confirmation
that refuses history rows and the session hosting the TUI, a new-session
case and CLI picker over quick-start, and degraded mode straight from
tmux when no server answers, re-probing so a server that starts upgrades
the dashboard in place.
Restoring the terminal is the part that has to be bulletproof: leave() is
idempotent and runs from normal quit, SIGINT/SIGTERM, a process exit hook
and prepended fatal handlers (src/index.ts already handles those by
exiting, so a listener registered after it would never run).
Attach is a handoff, never a proxy: the screen is restored and tmux gets
the real terminal. Inside tmux on the same socket there is nothing to
hand off to, so it issues switch-client and exits.
The preview pane, approvals answering, the prompt composer, search and
the digest are the next step; the region renders a placeholder rather
than pretending to load something.

The footer and the help overlay held the plan's full keymap, which would
advertise verbs (prompt, search, digest, answer, resume) that the build
does not implement yet and teach users that the TUI ignores keys. Both
now take their entries from the render options when the caller passes
them; the built-in lists stay as the fallback.
The picker overlay windows its items around the cursor rather than
clipping them, so the selected case stays visible in a long list.

The app layer repaints on state change, so the store has to be able to
say that something changed: `revision` is bumped by every mutating
method, and the repaint test compares it against the last painted frame.
Without it an idle dashboard would either redraw on a timer or go stale.
Three additions come with it, all optional so nothing existing changes
shape: `TuiSessionRow.muxName` (the unified list carries no mux name, so
the app fills it in from the local tmux enumeration and a row without one
cannot be attached), a `new-session` UI mode, and `TuiPickerState`, the
one-column chooser behind `n`.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Everything the dashboard needs from outside the process, behind one typed
surface, so the app loop stays a loop. It is a client of the running server and
nothing else: rows come from the unified list, blocked states from the
approvals inbox, and answering goes through the endpoint that re-captures the
pane and refuses with a 409 when the dialog has already been answered in tmux.
That refusal is a typed result rather than an exception, because a human
beating you to a prompt is normal operation.
Discovery mirrors the daemon probe (`CODEMAN_API_URL`, else loopback on
`CODEMAN_PORT`, self-signed TLS accepted) and credentials come from where
`codeman attach` already reads them. An explicit port outranks the ambient
`CODEMAN_API_URL`, which every managed session exports: a caller that named a
port must not be redirected at whatever server owns its shell.
Input is single-line and `\r`-terminated at this layer, so no caller can strand
text on an unsubmitted composer, and each send is tagged for the server's
exactly-once path. The event stream defaults to a `?sessions=` filter that
matches nothing, which drops the terminal firehose while lifecycle, hook and
approval events still arrive. A silent-but-open stream is caught by a watchdog
rather than a socket error, since that failure mode reports nothing at all.
With no server answering, sessions are listed from tmux on the instance socket
(argv, never a shell string) and decorated from a read-only peek at state.json,
which keeps the "the server died, get me to my sessions" path alive.
