start() reassigns _claudeSessionId to `resumeSessionId || id` on every launch,
including the path that re-attaches to a mux session that outlived the restart.
A pane whose CLI had moved on via /clear therefore came back pointing the
response viewer at its pre-/clear transcript, and because Session.lastSubmitAt
lived only in memory, the history correlation had nothing to correct it with
until the user happened to type again — observed as hours of the eye showing a
conversation the pane had long since left.
Persist lastSubmitAt in SessionState, restore it in restoreMuxSessions(), and
flush it when the viewer adopts (a /clear emits no completion event, which is
the trigger that would otherwise have persisted it). Recovered panes now
re-derive their live conversation on the viewer's first poll.
Restoring a stale anchor is safe: the resolver already refuses a candidate
transcript older than the one the pane is currently on, which is the shape of a
respawn into a fresh conversation.
The viewer re-derived a pane's live conversation from the newest
~/.claude/history.jsonl entry for the pane's cwd. A cwd is shared with every
other Codeman tab on it, with tabs long since closed, and with any plain
`claude` the user runs in their own terminal, so the eye followed whichever of
those was typed into last — and since the match was written back through
adoptClaudeSessionId(), the mispin stuck.
Credit a history entry to a pane only when it lands within 10s of that pane's
own Enter and no other pane on the same cwd submitted closer, reusing the
last-submit correlation the Codex locator already relies on. Submit tracking
moves from _codexLastSubmitAt to a mode-agnostic Session.lastSubmitAt. With no
correlated entry the pane keeps the id it has: a viewer one turn behind beats a
viewer showing someone else's conversation.
