"""E10 lifecycle-truthfulness probe suite (Amendment 2, Task 14).

Pre-registered prediction: `logs/2026-07-28-codex-efficiency.md`, "E10
PRE-REGISTRATION" entry (2026-07-30) -- built from audit Finding 7
("progress, lifecycle, and completion state were unreliable").

Four probes, each scored differently:

  (a) empty-output child -- does the controller record explicit failure
      when a spawned child returns a near-empty/null FINAL_ANSWER, or does
      it march on treating it as success? `is_null_child_result()` +
      `reconcile_child_check()`.
  (b) killed child -- scored externally by `probe-kill-child.sh`'s captured
      before/after rollout state; this module only classifies, it does not
      drive the kill.
  (c) tool-budget/timeout exhaustion -- scored by inspecting verdict.json
      + the last rollout state at a forced `quorum_max_time` cutoff.
  (d) citation-integrity -- `citation_check_run()`: extracts claims (merge,
      test-count, file-creation) from a run's ROOT final_answer and checks
      them against the run's own `coding-agent-workdir` + `exec_commands()`
      tree. Claim-extraction regexes are calibrated against real phrasing
      sampled from this campaign's own corpus (see module docstring in
      test_score_e10.py) -- not invented shapes.

Also carries the reframed lifecycle-reconciliation census
(`mentions_unfinished_child()`): per this task's explicit instruction, a raw
close_agent count is not a truthfulness signal under multi-agent V2 (LRU
eviction is structural, not discipline -- see
docs/2026-07-29-codex-multiagent-v2-capabilities.md); what matters is
whether a controller's own final claim ever acknowledges an unfinished/
failed child.

Usage: score_e10.py [--force]
Prints a markdown report to stdout (MINE-tier scan of the existing
`cx-eff-*` battery corpus). Writes an aggregates-only JSON blob to
campaigns/codex-efficiency/out/e10-battery.json (refuses to overwrite an
existing file unless --force or env FORCE=1 is set, matching every other
scorer's convention). Read-only otherwise -- coding-agent-workdir file
existence checks are `os.path.exists`, never a write.
