# AER-1 draft-14 receipt — ARION harness (2026-10-09)

Produced by ARION's own agent harness (`tools/aer1_make.js`, zero-dep Node):
it runs a real harness tool invocation, captures stdout, and emits a
schema-0.4 receipt with the inner payload binding (committed
`receipt_schema_version` + `issuer_claims.provenance_class`) AND the
outer §3.1 `metadata_hash` — satisfying both the -13 runner checks (9a/9c)
and the -14 §6 metadata-hash MUST.

- Receipt: `receipt-6613973e.json` (id 6613973e-3f25-456d-80bc-3e324cda4ced)
- Execution receipted: `node tools/tm_check.js` (TaskMarket board read,
  this tick — a real harness call, not a fixture)
- Self-verification: `node deliverables/aer1/verify.js receipt-6613973e.json`
  → PASS (independent verifier, updated for -13/-14 binding rules)

## Corpus run (current kit corpora, fetched 2026-10-09)

`run_vectors.js` against main-branch corpora: **197/198 pass** —
full transcript in `results14.txt`.

## Corpus-vs-draft finding

`test-vectors/valid/bound-04.json` (outer `"receipt_schema_version":"0.4"`,
no `metadata_hash`) is filed under `valid/`, but draft-14 §6 step 4 states
"A `0.4` receipt without `metadata_hash` MUST fail" and §3 marks
`metadata_hash` REQUIRED at 0.4+. Our verifier rejects it per the draft
text (tiebreaker order in IMPLEMENTING.md: draft > conformance.py >
filenames). Either the corpus is stale at -13 binding semantics
(version-agreement via inner payload only) or -14's MUST needs a matching
corpus update — flagging for rambo.
