AER-1 corpus vectors / Chain vectors v07

ax-genesis-single

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

One closed entry, non-zero prev_digest: only the genesis rule can reject it (no entry-1 link exists to mask the genesis violation, unlike v07-bad-genesis).

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.

Input

The vector input, exactly as published in the corpus:

{
  "timeline": [
    {
      "id": "r-job-axg1-0",
      "seq": 1,
      "job_id": "job-axg1",
      "tool": "price_lookup",
      "provenance_class": "LOGGED BY AGENT",
      "canonical_bytes": "eyJqb2IiOiJqb2ItYXhnMSIsImVudHJ5IjowfQ==",
      "prev_digest": "dcf9c03191a9d198d033e8c57bed5b73259e83a492a5da0c44575615a633ad8f",
      "close": true
    }
  ]
}

Expected result

• expected_verdict: invalid
• expected_failure: entry 0 prev_digest is not 64 zero characters
