Disclosures

Stablecoins are test-policy stand-ins (tUSDM/tUSDCx minted by this repo's operator) for the verified USDM / USDCx policies used at mainnet.
Pyth updates are fixture-signed on testnet: real Lazer "solana" wire format, real feed ids and exponents, ed25519 over the payload, signed by this repo's declared fixture publisher key with synthetic prices. Mainnet swaps verification to the live Pyth state/withdraw scripts (already deployed by Pyth) and live Pyth Pro updates; the consumption shape is identical. The on-chain parser handles the fixed one-feed price+exponent layout; production uses the official pyth-lazer-cardano library's parser.
KERI infrastructure is self-hosted: one KERIA agent with three separate client key stores and the standard demo witness pool; trader AID aliases ("ascend-investor-N") predate the rails naming.
Settlement timing (settle_after) is enforced against the attested update timestamp, not an on-chain clock; production adds tx-validity staleness bounds per the Pyth docs.
Metadata label 7368 (Ascend app data) is unregistered; CIP-0170 is Proposed status; shapes pinned to the CIPs repo text.
This is testnet TRL5 evidence, not the audited mainnet build; the mainnet deployment goes through third-party audit per the funded plan.
