/-! ## 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.
