EXECUTED case_msskp1gg956f8a 2026-08-14 · SupraFX Mainnet · micro-live
Scope of this proof: one mandated micro-trade (sell 1 SUPRA against USDC, max notional 169 micro-USDC) executed by an agent under delegated authority, a one-shot signed mandate, a hash-pinned policy and a human ARM ceremony — closed with a signed receipt whose internal consistency verifies on ten criteria.
Public evidence bundle. Offline verification uses the public COSMO verifier at heros.cloud/verifier/ (one self-contained file, no npm, no network) — a separate offline verification of internal consistency, not an independent third-party attestation.

Two receipt hashes, both correct: the receipt statement hash is calculated
from the canonical JSON representation of the signed receipt (sorted keys, no
whitespace — this is the value recorded in the journal’s case_closed
entry). The published file hash is calculated from the exact downloadable
file bytes, including its final newline.
Settlement amount — technical note
The platform API returned a JavaScript floating-point balance delta
(0.00016899999999964166 in the raw observation). The normalized economic
amount is 169 micro-USDC — “exactly the mandated
rate” refers to this normalization. Future adapters should use integer micro-units
end-to-end; this fix has since landed in the COSMO engine.

The 12 evidence files (everything except receipt.json, MANIFEST.json, journal.jsonl and the
indexes) match the 12 MANIFEST.json entries byte-for-byte; MANIFEST is sealed into the
receipt as evidence_root.
What verification checks (K/S/T/P/M/V/J/E/D/O)
- K — attestor key pin: the signing key is pinned in the trust store.
- S — receipt signature: ed25519 over the canonical envelope + statement.
- T — time bounds: attestation time within sane limits.
- P — policy pin: the policy hash matches the pinned, active policy.
- M — mandate integrity: recomputed hash, signature, case and policy binding.
- V — evidence integrity: manifest vs. directory, exact set, per-file sha3.
- J — journal chain: every entry hash-chained, opened first, closed last.
- E — execution envelope: BCS decode, local signature verify, mandate linkage.
- D — derivation equality: the receipt statement re-derives byte-identically from the evidence.
- O — outcome consistency: outcome matches the evidence the case actually produced.
Result for this case: ACCEPT, 10/10 criteria, exit code 0 — a separate offline verification of internal consistency, run with the public COSMO verifier at heros.cloud/verifier/.
Honest limits
· This receipt is a self-attestation by the COSMO engine: one attestor, no independent attestor network.
· Verification proves internal consistency and record integrity — not world truth.
· settlement_ref is an observation of platform balances, not a native chain proof.
· One venue, one pair, micro scale. Supervised agent execution with explicit human authorization at the irreversible boundary — the human ARM step is part of the proven authority model, not a shortcut.
· Full 10/10 verification uses the public COSMO verifier at heros.cloud/verifier/ (a self-consistency check, not a third-party attestation).
