Closes ticket #000009 zero-shot. Scope expanded to cover BOTH
ticket #000008 (broad-quantifier) AND ticket #000010
(meta-cognition) preflight contracts in a single combined node —
both share the same audit-replay gap and inserting two separate
nodes between question and retrieval was operationally awkward.
aborist/qa/dag.py:
+ preflight_node_hash() — combines QuestionState +
quantifier classifier output + behavioral policy_state into
one canonical SHA-256 hex.
+ build_run_dag() gains optional preflight_hash parameter.
When supplied, inserts {"stage": "preflight", "hash": ...}
at position 1 (between question and retrieval).
Backward-compat: None → original 7/9-stage shapes preserved
for legacy run_dag_root re-validation.
Quote-mode: 7 → 8 stages with preflight.
Pointer-mode CTI: 9 → 10 stages with preflight.
aborist/qa/query.py + runner.py:
Both build the preflight payload from question_state +
quantifier dict + 10-field policy_state (guard_enabled,
guard_apply_caps, guard_apply_caps_mode_gated,
claim_cap_resolved, claim_cap_actually_applied,
reminder_enabled, reminder_eligible, reject_broad_active,
metacognition_enabled, block_on_contradiction).
This means two cache rows that share the same question + same
model output + same verifier verdict but DIFFERENT preflight
policy state now produce different run_dag_root values. Audit
replay can pin the policy decision per row.
9 new tests in tests/test_dag.py:
- preflight_node_hash determinism
- hash bumps on question_state change
- hash bumps on policy_state change (the audit-replay payoff)
- all-None defensive shape
- 7→8 stage transition (quote mode)
- 9→10 stage transition (pointer mode), preflight at index 1
- run_dag_root bumps when preflight_hash bumps
- verify_run_dag round-trips through preflight stage
Live verification: latest providence_cache row carries
['question', 'preflight', 'retrieval', 'evidence_map', 'prompt',
'raw_answer', 'parsed_claim_lattice', 'verify', 'render',
'final_label'] — preflight stage living in the persisted DAG.
987 tests passing (9 new); 36 skipped.
