"""Rationalization-interrogation runner (see docs/rationalization-interrogation-method.md).

For each rep dir: locate a target event in the controller (largest)
rollout, extract surrounding context, and elicit RATIONALIZATION /
TRIGGER / COUNTER from the same model family. Output goes to stdout for
controller transcription into the campaign log — this instrument never
writes verdicts.

Usage:
  interrogate-rollout.py --rule "the instruction that was in force" \\
      --act "what the wrong act was, one sentence" \\
      (--exec-match REGEX | --message-match REGEX) [--nth -1] \\
      [--seat controller] [--model gpt-5] [--window 6] REP_DIR [REP_DIR ...]

Event selection: --exec-match finds exec (command) events whose text
matches REGEX; --message-match finds agent messages matching REGEX.
--nth picks which match (default -1, the last). The elicitation prompt
carries the --rule text verbatim as "the instruction in force" and
--act as the description of the divergent act.

Seat selection (--seat, default controller):
  controller   the largest rollout in the rep (the orchestrating session)
  reviewer     child threads (session_meta.parent_thread_id set) with ZERO
               patch_apply_end events (read-only seat); every matching
               reviewer child is scanned, first event match wins
  implementer  child threads WITH patch_apply_end events
Seat misattribution poisons elicitations silently — verdict-marker text
appears in the controller's dispatch prompts too, so text-matching alone
selects the wrong seat (this bit the X5 interrogation once: controller
setup habits were elicited under a reviewer framing).

Auth: OPENAI_API_KEY from env (never printed). Post-hoc-confabulation
caveat: outputs are hypotheses for battery testing, not verdicts.
