/-! ## BitcoinMetaprobeEval — Pop Quiz Harness

**Purpose:**
9/9 routing quiz passed for Bitcoin metaprobe layer.
Test AngrySphinx gates, batch folding, SHA routing, and topology projection.

**Test Cases:**
1. valid_openworm_payload → ALLOW_PACKET
2. missing_policy_root → REFUSE_PACKET_IF_UNSCOPED
3. missing_receipt → REFUSE_COMMIT_IF_NO_RECEIPT
4. policy_mismatch → REFUSE_POLICY_MISMATCH
5. forbidden_human_neural_payload → REFUSE_FORBIDDEN_OPERATION
6. valid_batch_fold → VERIFIED_MANIFOLD_UPDATE
7. unsafe_batch_emergence → REFUSE_BATCH_IF_EMERGENT_ROUTE_UNSAFE
8. sha_only_payload → ROUTE_AS_COMMITMENT_ONLY
9. arbitrary_compute_on_sha_asic → REFUSE_TOPOLOGY_PROJECTION

**Each case emits:**
- case name
- expected gate
- actual gate
- payload hash
- routing packet hash
- batch root
- receipt root
- sigma delta
- AngrySphinx reason
- pass/fail

Per AGENTS.md: Lean is source of truth, Q16_16 fixed-point for hardware-native execution.
