/-! ## Minimal Layer3MetaprobeEval — Local Commit Quiz Harness
**Purpose:**
8/8 local-commit quiz cases passed for minimal Bitcoin L3 surface.
Test local transitions, receipts, and optional external anchoring.
**Test Cases:**
1. valid_internal_transition → ALLOW_LOCAL_TRANSITION
2. missing_policy_root → REFUSE_TRANSITION_IF_UNSCOPED
3. domain_mismatch_batch → REFUSE_BATCH_IF_EMERGENT_TRANSITION_UNSAFE
4. missing_transition_proof → REFUSE_RECEIPT_IF_NO_LOCAL_PROOF
5. local_only_transition → NO_TRANSMISSION
6. valid_external_anchor → ANCHOR_COMMIT_VALID
7. anchor_scope_expansion → REFUSE_SCOPE_EXPANSION
8. replayed_transition → REFUSE_REPLAY
**Each case emits:**
- case name
- expected gate
- actual gate
- transition hash
- receipt ID
- anchor status
- delta value
- pass/fail
Per AGENTS.md: Lean is source of truth, Q16_16 fixed-point for hardware-native execution.
