# Golden trace capture for pmat CLI dispatcher (PMAT-611).
#
# Writes a renacer-native baseline (manifest.json + syscalls.trace +
# timing.stats) at `golden_traces/baseline/`. The `pmat work complete`
# quality gate runs:
#
#   renacer validate --baseline golden_traces/baseline --ignore-timing \
#       -- ./target/release/pmat --help
#
# so this script captures the same flow. Extra dispatcher flows (version,
# list, hooks status) are captured into subdirectories for operator use;
# they are not consulted by the work-complete gate but make regressions in
# unrelated code paths easy to inspect with `renacer validate`.
#
# Usage: scripts/capture_golden_traces.sh
#
# bashrs-disable: SEC010 SEC011 SEC014 SC2114 SC2320

#   SEC011/SC2114: `rm -rf` targets use `${var:?}` guard below
