AER-1 corpus vectors / Chain vectors v07

x-encoding-reference

Family: Chain vectors v07. Source: base/chain-vectors-v07.json in the AER-1 corpus published at zambo.dev/aer1/corpus.json (kit 1.5.7, draft-zambo-aer1-26), file SHA-256 d72b815585afdb075311da892f54041c9ffd5e7d875afbf32bd8165c3ca9ea94.

What this vector covers

Links computed with the reference encoding: lowercase \u hex, \n short escape, U+007F escaped

Rule it exercises

draft-zambo-aer1-07 Section 7: entry digest = SHA-256 over the UTF-8 bytes of the canonical JSON object {prev_digest, seq, job_id, close, id, tool, provenance_class, output_hash} (keys sorted by Unicode code point, no whitespace), where output_hash = lowercase hex SHA-256 of the base64-decoded canonical_bytes. Entry 0: prev_digest is 64 zeros and seq is 1. seq contiguous from 1. One job_id per chain. close is boolean, true only on the last entry. Honest limit: truncation of either end with re-linking is not detectable by chain mechanics alone; it needs an anchored endpoint.
