PANE_FORMAT now carries #{window_activity}, #{window_panes}, and
#{pane_title} (title last — it may contain tabs; parse_panes splits
bounded and degrades missing/empty tails instead of dropping the pane).
The remote probe appends a date +%s reading behind a second marker so
activity freshness is judged on the remote's own clock, skew-free.
merge_status orders the evidence: visible blocker > viewer overlay
(keep_previous, resolved against the previous status at snapshot apply)
> live working tell / fresh output > positive idle tells > weak
passthrough. Fresh output sits above the idle tells deliberately: a
previous turn's completed line lingers on screen while the next turn
streams, and only live evidence may keep Working lit.
Verified live on codex-cli 0.149.1: the pane title cycles
work -> "⠧ work" mid-turn -> work, spinning through the streaming
phase the buffer misses, while window_activity tracks output and
freezes at completion.

docs/agent-status-plan.md(stacked on #102 — merge that first; this diff shows only the delta once GitHub retargets).PANE_FORMATgains#{window_activity},#{window_panes},#{pane_title}— title last and bounded-split, since titles are arbitrary program text that may contain tabs. Missing/empty tail fields degrade toNone, never a dropped pane, so older remote tmux keeps working.date +%sbehind a second shell-safe marker: activity freshness is judged against the remote's own clock, so ssh-host clock skew never enters the freshness window.

Fresh output deliberately outranks the idle tells: a previous turn's "…ed for N" line lingers on screen while the next turn streams.window_panes == 1(it is window-scoped; a split's neighbor would masquerade as agent output).Verified live (codex-cli 0.149.1)
Idle title
work→ mid-turn⠧ work(spinning through the text-streaming phase, which the buffer classifier cannot see) → back toworkat completion;window_activityadvanced with output and froze the second the turn ended. This closes the streaming blind spot for Codex two independent ways (title + clock); for Claude 2.1.241 (whose title never spins) the clock is the one that closes it.Tests
772 workspace tests pass; new table-driven tests for
merge_status/activity_fresh, parser tolerance tests for old/truncated tmux output.🤖 Generated with Claude Code
