Issue #5518 (Epic #5508 Phase 1c) -- the exact scripts run to produce the
evidence in this directory's parent.  Nothing here is repo source: the witness
capture is a PYTHONPATH `sitecustomize` OBSERVER (harness5508/sitecustomize.py),
so the run tree's `git diff --stat` was empty for every arm.

Drivers (run from the repo/worktree root):
  run_board05.sh <repeat>            board-05 legacy DRV8301 entry point
  run_board06_arm.sh <on|off> <rep>  board-06 recipe; "off" forces the
                                     pre-#5504 avoidance leak via
                                     KCT_5508_FORCE_AVOIDANCE_LEAK=1
  run_board07.sh <repeat>            board-07 recipe, no harness
  run_board07_witness.sh <repeat>    board-07 recipe + harness targets
                                     (U4.C2, U1.28, U2.4)
  run_board05_replays.sh             offline witness replay of every board-05
                                     journal dump, layer stack stated
  run_drc.sh / run_drc_batch.sh      kicad-cli pcb drc --refill-zones gate
  run_netstatus.sh / *_batch.sh      kct net-status --why capture

Harness env contract (see the sitecustomize docstring):
  KCT_5508_WITNESS_OUT    capture path prefix; unset => harness inactive
  KCT_5508_REPLAY_IN_RUN  1 = in-process witness replay (boards 06/07)
                          0 = journal+snapshot dump only (board-05: the
                              deadline leaves ~5 s before SIGKILL)
  KCT_5508_TARGET_PADS    REF.PIN terminals to interrogate explicitly
  KCT_5508_FORCE_AVOIDANCE_LEAK  1 = clear_avoidance_after_connection=False
