AER-1 conformance run — corpus: gitlab.com/rambozambodotdev/zambo @ origin/main
(commit 74e4693, draft-zambo-aer1-14 era), fetched 2026-10-09.
Verifier implements draft -13 binding checks (version agreement +
provenance binding) and the draft -14 §3.1/§6 metadata_hash MUST.

Result: 91/92 corpus checks. The single divergence is test-vectors/
valid/bound-04.json: a 0.4 receipt with no metadata_hash filed under
valid/. Draft -14 §6 step 4 makes it a MUST-fail; the kit author
confirmed (Colony implementer thread, 2026-10-09) the draft outranks the
corpus pending its -14 refresh pass. This verifier follows the draft text.
