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.

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.

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.

Node has no EventSource, so the live-update stream is read as raw bytes and
decoded here. Three details are what the parser exists for: a TCP read can end
between the CR and the LF of a CRLF, so a trailing CR is held back rather than
dispatched; the tunnel padding the server appends after a frame is a comment
with no blank line after it and must not split anything; and the keepalive is a
NAMED event, because an SSE comment is invisible to a browser client by spec.
Event classification lives here too, as a set rather than a prefix test:
`session:terminal` is most of the stream and the preview pane pulls its own
tail, so it is deliberately not a resync trigger.

One absolutely-addressed line per row, each closed with an erase-to-end, so
nothing scrolls and a repaint cannot leave the previous frame's tail behind.
The caller wraps the result in synchronized-output brackets; that is an IO
decision and stays out of the renderer.
Color is passed in rather than detected. chalk's detection is right for the
one-shot CLI but would make a frame non-deterministic, so the palette is raw
SGR in the same semantic roles cli-style uses, and `color: false` emits nothing
but the cursor addressing, the session's own colors in the preview included.

Below 72 columns the preview pane is dropped and rows take two lines, the
constraint the `sc` chooser was built around and the reason it is still usable
on a phone; above it a clamped sidebar carries the list and the preview takes
the rest.
Every region is clamped to a non-negative size, so a 5x5 terminal degrades to a
header instead of handing the renderer negative widths.

Rows are the ones GET /api/sessions/unified already returns and blocked states
are the items the approvals inbox already parsed, both imported as types only
so a CLI process pulls in neither the server nor node-pty. Classification
speaks the web UI's language (red blocked, yellow waiting, green working) so a
user with both surfaces open never has to translate between them.
Groups order by how long a session has been in its state, which is why WORKING
anchors on the pane's last Enter: a working pane repaints about once a second,
so its last-activity stamp always says "now".
Selection is tracked by session id, never by row index: rows re-sort under the
cursor whenever a session starts working or an approval lands, and an
index-tracked cursor would quietly move the selection to another session
between two keystrokes.

Decodes printable UTF-8, the control keys, arrows in both CSI and SS3 forms and
SGR mouse reports out of a byte stream that can tear anywhere, so a sequence
split across two reads decodes the same as one that arrives whole.
A lone ESC cannot be told from the start of an arrow key by looking at bytes,
so the parser holds it and the caller resolves it with flush() once its
disambiguation timer fires. Unknown sequences are swallowed: a stray CSI must
never reach a prompt composer as typed text.

The preview pane shows a session's raw terminal stream, so it needs the tail
reconstructed rather than emulated: SGR survives, cursor steering and OSC do
not, and a carriage return returns to column 0 so a spinner that repaints its
line 200 times contributes one line instead of 200.
Widths count East Asian Wide characters as two columns, which the clip and pad
helpers rely on to never cut a wide character, a code point or an escape
sequence in half.
