Stacks on top of the base commerce-payments port. Adds the x402r-specific layer: - payment-operator: factory + slot dispatch. create_operator allocates a per-merchant OperatorState PDA at ["operator", authority] whose address IS the merchant's operator pubkey. Wraps escrow authorize/capture/void/ charge/refund with pre-action conditions + post-action hooks, CPI'ing into escrow as the per-merchant PDA via invoke_signed. update_operator rotates the slot config under the existing authority. - static-address-condition: generic ICondition reference impl. Outer signer must equal a configured target. - receiver-condition: stateless ICondition. Outer signer == payment_info. receiver. - payer-condition: stateless ICondition. Outer signer == payment_info. payer. - fuzz_slot_dispatch: Trident scaffold for fuzzing the slot fan-out. - Re-adds the slot-dispatch test cases removed from the base PR. Workspace plumbing (Anchor.toml, Cargo workspace, codama generator, pin-program-ids, fuzz Cargo) is updated to include the new programs. reclaim stays on the escrow and is called by the payer directly: it intentionally bypasses the operator program so the payer's deadline- based escape hatch cannot be defeasibly delegated. Status: pilot, unaudited. Mainnet usage is at users' own risk. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Stacks on top of #2 (base commerce-payments port). Adds the x402r-specific layer on top of the escrow primitive — the second half of the two-PR split of #1.
