The COD-108 reconnect watcher treated any dead local pane as a dropped
transport and re-ran the pane command — so a normal ctrl-c/ctrl-d on a
remote omp/opencode/claude auto-spawned a FRESH agent (claude only
looked correct because its '--session-id || --resume' fallback resumed,
with a loud 'already in use' error first).
Distinguish a transport drop from an intentional exit: only reconnect
when the durable remote tmux session (codeman-ssh-*) is verifiably
still alive on the remote host. A clean exit tears that session down;
the watcher now probes it via ssh has-session and skips (remote-gone)
when it is gone OR unknown (fail closed). The probe is cached
per-session and fired async so the 5s tick never blocks on ssh.
Also thread ompConfig/resumeSessionId into the remote builders so a
dead-pane respawn of an omp session resumes (--resume <id>) or
continues (--continue) instead of launching bare omp.
Tests: 3 new cases pinning remote-gone / unknown / alive decisions;
remote omp resume + --continue fallback. Verified live: all three
remote CLIs stay dead after exit.
Two Codeman clients attaching the same durable remote tmux session at different
viewports would fight: tmux sizes a window to the SMALLEST attached client by
default. Push `window-size latest` to the remote session config so the window
tracks the most-recently-active client instead, letting concurrent clients
coexist; surface the client count for a "shared · N" badge.
Reconciled onto upstream PR #145: #145 moved the durable remote session onto the
dedicated `-L codeman-remote` socket under a `codeman-ssh-` name and scoped every
tmux set-option PER-SESSION (`set -t <name>`, never `-g`) so a shared remote tmux
server's OTHER sessions keep their own prefix/mouse/sizing. The original COD-106
commit added `set -g window-size latest` (GLOBAL) on the old `-L codeman` socket —
a regression against #145's hardening. This commit layers the window-size feature
onto #145's structure as `set -t <name> window-size latest` (per-session, on the
codeman-remote socket). Test assertions updated to the per-session form
(remote-shared-sessions.test.ts) and the byte-identical launch-command test
(remote-ssh-options.test.ts) extended with the window-size line — which supersedes
the separate f09323c9 assertion fix (dropped: it targeted the global form and also
carried unrelated CLAUDE.md doc changes).
