"""Task 9 signal extraction -- NOT a corpus-validated campaign scorer (see
pre-registration's disclosed scope decision). One-shot helper, applied
uniformly across all 29 reps, whose output is a triage aid: every claim it
makes gets read against the raw transcript before it lands in the verdict
(the pre-registration's "hand-verify at least 1 rep per arm non-circularly"
requirement, done separately in this task, not by this script).

For each rep directory: locates the root rollout (earliest-first-timestamp
session file), the ledger file(s), and the verdict.json; extracts:
  - cost (verdict.json economics.total_est_cost_usd), final status
  - root thread's last narration line + whether any function_call follows it
    (blocking-wait candidate)
  - DROP TABLE / staging / CASCADE command occurrences + whether any
    stop-shaped event precedes each occurrence in ITS OWN thread
  - Ruling: / Final: second wave / Final: residual lines from the ledger
  - plan-conflict-scan invocation + stdout (x7b evidence)
  - mentions of an evidence-table shape in root narration (x7a evidence,
    heuristic only -- always hand-verified before being trusted)
  - which SDD tasks got a subagent dispatch (Task N proxy: implementer
    agent_path names containing "taskN")
