GET /api/sessions/:id/terminal runs synchronous tmux calls on the server, so
N tiles loading at once would stall every WebSocket and SSE stream back to
back (and after a deploy restart all N reopen within the same second).
TerminalTile takes the options PR 1 deferred to the grid:
- scheduleLoad(tile, kind, run): every capture the tile fetches (initial
load, reconnect refresh, server {t:'r'} refresh, shell history pull) runs
when its owner says so. Absent (the split's Pane B), a load runs at once.
- scrollback (the grid passes TILE_SCROLLBACK) and fontSize.
- boundedLoad: a TUI tile loads the bounded full=1&tail= window, never its
whole history.
TileLoadQueue (terminal-tile.js, DOM-free) is that one queue: concurrency 1,
a history pull ahead of background refreshes, then the owner's rank (the grid
ranks the focused tile first, then reading order). A destroyed tile's waiting
loads are dropped unrun, and destroy() aborts the running fetch so the queue
moves on.
Also, for Pane B as well: the load now has a deadline covering the body
(CodemanFetchDeadline), so a capture that never answers cannot hold the
single-flight flag (or the queue) forever; a refresh clears the screen at its
turn rather than when it is asked for; and a close while a load only waits in
the queue writes the disconnected marker at once.

A Codeman restart (every deploy) or a network blip used to leave Pane B
dead, with a marker asking the user to close and reopen the split.
TerminalTile now reconnects:
- A transient close reconnects on the primary pane's backoff ladder
(CodemanWsReconnect) plus jitter; the attempt count resets only on a
successful open. The redelivery sweep's forced close (1005) counts as
transient.
- On reopen the closed state is cleared before the buffer refresh that
closes the output gap, so no stale marker lands under a healthy pane.
- 4003/4004/4009/4010 stop the pane for good and report once through a
new onExit(code) callback; the marker says why.
- Sockets are replaced race-free: the old one is detached before a new
one opens, and every handler ignores events from a socket that is no
longer current. destroy() cancels a pending reconnect.
- reconnectNow() lets an owner skip the backoff.

Pure move and rename, no behavior change. The split pane's second
terminal (SplitTerminalPane) moves out of terminal-split.js into its own
terminal-tile.js (load order 7.4) as TerminalTile, so the tile grid can
reuse it. terminal-split.js keeps the split orchestration (picker,
divider, auto-collapse) and constructs a TerminalTile for Pane B.
Tests follow the class: split-pane-terminal-unit becomes
terminal-tile-unit, and the Shift+Enter guard and the two browser suites
read terminal-tile.js / window.TerminalTile. The browser suites match
master (one pre-existing environmental failure in both).
