Found in production: rust-mutation emitted WAITING-UNTIL 3h11m out for a cargo-mutants run over the whole
workspace (a genuinely multi-hour job, cargo running the whole time), but the marker branch skipped the
build-aware check entirely and went straight to the cap — so the 7200s cap would have killed a live run and
thrown away hours of work. The cap exists to catch a session that PARKED itself and is stuck; a build still
running under the session is proof it is not. Now the cap only fires when idle exceeds it AND no build is
running. The stated deadline remains the hard bound either way, so a runaway still cannot park forever.
Tests: cap-reboots-when-no-build, cap-yields-to-a-live-build, past-deadline-reboots-even-with-a-build. 68 pass.
_parse_waiting_until scanned only the pane's last non-empty line for footer_ui backends (claude/
opencode) — but their input-box footer always renders BELOW the agent's final message, so the marker
was never seen and WAITING-UNTIL was effectively dead for claude agents. It's only consulted once the
pane is already idle, so scan the whole capture and take the most-recent marker (the footer never
contains it). Add waiting_until_max (default 7200s) so an agent can't park its own reboot forever.
Tests: footer-honors-marker-above-footer, takes-most-recent, defer + cap in stall_check_one; make the
stall harness's patch() idempotent so a re-patched name doesn't leak into tearDown. 66 pass.
13 tests across 4 classes: the build-proc match set (build tools match; python/node/bash/claude and
substring look-alikes don't), _proc_descendants (real child tree, roots excluded), _build_running
(session-scoped, comm-matched, never the claude root, custom regex override), and stall_check_one's
defer/reboot/hard-cap behavior. Full suite 64 pass.
Unit tests (no agents/tmux): config load + defaults merge, kickoff-template
assembly, phase machine (advance/idempotent-complete/append-resumes), limit
reset-banner parsing, WAITING-UNTIL/stall parsing, claude+opencode activity
detectors. Live smokes bring a throwaway project up THROUGH agents.py on each
real backend in an isolated sandbox (unique prefix, opencode on a non-4096
port), verify attach + status + down, and clean up. tests/run.sh runs unit
always + smokes when backends present; README documents it.
