PR #48 closed; treat the implementation as starting from
main, where no tmux integration exists yet. The PRD now
describes the full design (including the `_in_tmux` detection
+ helper scaffolding) as fresh work. Sized into 4 chunks:
`claude_docker_argv` refactor → tmux helpers + pane state +
`_attach_to_bottle` dispatch → new-agent flow → stop +
indicator.
Same design as before — opt-in by `\$TMUX`, split-window-then-
respawn, falls back to handoff on tmux failure or missing
binary. No external references to PR #48.
Draft a PRD that tightens PR #48's tmux integration from
"one new window per attach" to "one persistent right pane that
the dashboard's selection drives." Inside tmux (`\$TMUX` set):
dashboard in the left pane; pressing Enter or `n` spawns
claude in the right pane via `tmux split-window` on first
attach, then `tmux respawn-pane` on subsequent attaches so the
operator-focused agent is always the visible one.
Outside tmux: falls back to today's handoff. Opt-in by
environment; no flag.
Sized into 4 chunks (pane state + create → respawn → stop
integration → supersede PR #48's new-window). Seven open
questions called out, the biggest being whether the dashboard
should auto-exec into a fresh tmux session when launched
outside one (v1 says no — operators start tmux themselves).
