Sample Receipt

A live defendablecloud.eval-receipt/v1 minted by DefendableCloud on an Agent Work eval Run. This is the canonical receipt body built by build_eval_payload — flat top-level keys, no wrapper:

How to read this

receipt_id: DCR-000004-a83e1f7c — format is DCR-{org_seq:06d}-{hex8}. The six-digit number is the org sequence; the hex8 suffix is a per-receipt id fragment.
org_seq: 4 — the 5th receipt for this org. The chain is per-org and sequential starting at 0. The genesis receipt (org_seq: 0) carries parent_hash = sixty-four zeros.
parent_hash — points at the prior receipt’s receipt_sha256. Walk the chain back to org_seq: 0 to verify; /ledger/verify recomputes every hash and checks the sequence + parent links.
verdict.severity: propolis — one high-tier flag. score_100: 88 is the % of declared rules satisfied, weighted by tier — mechanical, not a quality opinion. client_ready is a string (the human-readable readiness note), not a boolean.
findings — only the flagged rules ride here, each with the rule’s declared severity (e.g. critical). The full applied-rule list is on the verdict page.
share_url — the public /share/{token} URL. Anyone can view + verify, no auth required. A PDF is regenerated on demand at /share/{token}/pdf.

Where the hash lives

receipt_sha256 is not embedded in the body. The chain coordinates (org_seq, parent_hash) are part of the canonical body that gets hashed; the receipt_sha256 itself is computed over that canonical JSON (orjson, sorted keys) and returned in the Receipt envelope by POST /runs/{id}/receipt at mint time (and re-served at GET /share/{token}):

{
  "receipt_id": "DCR-000004-a83e1f7c",
  "org_seq": 4,
  "parent_hash": "9c2f...8c0f",
  "receipt_sha256": "a83e...77f1",
  "share_token": "shr_3f7c8d21",
  "share_url": "https://api.defendablecloud.com/share/shr_3f7c8d21",

}

What’s not in this receipt

No external chain transaction id. No Hedera HCS topic. No blockchain anchor. The chain is the in-house per-org hash chain, persisted in Postgres. (See Kill Hedera doctrine.)
No PDF blob. The PDF is regenerated from the body via fpdf2 on demand. Tigris artifact upload (JSON + PDF) is best-effort — a storage outage never blocks a receipt; the chain lives in Postgres.
No model “quality grade.” The verdict carries score_100 (% rules satisfied) and severity (flag-driven). Both rule-driven, neither an opinion.
