Direct port of base/commerce-payments authCapture primitives to Solana. Mirrors scheme_exact_svm.md style: partial-tx + facilitator-cosign auth model, single numbered protocol flow, bullet-list extra fields, MUST list verification rules. Two on-chain primitives: - auth-capture-escrow: AuthCaptureEscrow analog - spl-token-collector: ITokenCollector impl for SPL Token Higher-level patterns (operator factories, multisig, plugin slots) are out-of-scope x402r extensions. Pilot status: unaudited; mainnet usage at users' own risk. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

specs/schemes/authCapture/scheme_authCapture_svm.md— a faithful SVM port ofbase/commerce-payments's authCapture primitives.auth-capture-escrow(analog ofAuthCaptureEscrow) andspl-token-collector(analog ofEIP3009TokenCollector/Permit2TokenCollector).scheme_exact_svm.md. ERC-3009 / Permit2 don't exist on SVM and aren't needed — runtime signature checks ARE the authorization.scheme_exact_svm.md: title format, single numbered Protocol Flow, JSON examples + bullet-listextrafields, MUST list verification rules.Pilot status; unaudited. Mainnet usage is at users' own risk — flagged at the top of the doc.
