Verifiable Intent
Treeship and Verifiable Intent, by Mastercard.
Treeship 0.31.2: sealed packages now verify their signatures
package verify checked the Merkle tree and nothing under it. It now verifies every artifact's Ed25519 envelope, session close seals unchained work, and the MCP bridge reports failures.
Treeship 0.31: Verifiable Intent credentials, shipped
treeship vi implements the Verifiable Intent v0.1 draft, signs the Layer 3 pair with a Treeship receipt-chain attestation inside, and interoperates with the reference SDK both ways in CI.
