- gstack-qa-evidence capture prints startedAt/completedAt/durationMs and, for
--deadline captures, remainingMs; the functional report takes durations from
them. The section clock notice asks for one clock read up front instead of one
after every checkpoint (QA runs spent 7-14% of tool calls on date -u).
- ship plan-completion: skip the audit dispatch when discovery already found no
plan (the dispatch-vs-skip conflict produced an optional 60-100 s subagent).
- materialize/checkpoint validation errors state the expected schema, so a
rejected annotations file is fixable in one call instead of blocking the phase.
- session-runner counts turns from the transcript when a run times out, so
timeouts stop reporting 'turn 0'.
