AER-1 corpus vectors / Chain vectors
chain-truncated-no-close
Family: Chain vectors. Source: base/chain-vectors.json in the AER-1 corpus published at zambo.dev/aer1/corpus.json (kit 1.5.7, draft-zambo-aer1-26), file SHA-256 10de1cadb45b8d5c91ae94a601c6bb567aab59b26e89abbbb64af6896d3aba19.
What this vector covers
Valid chain with the closing entry removed; last entry lacks close=true.
Rule it exercises
draft-zambo-aer1 Section 7 (normative): entry digest = SHA-256 over base64-decoded canonical_bytes; prev_digest links entries; genesis prev_digest is 64 zeros; timeline must end with a closing entry carrying close=true
