Preview a non-executing External Source Scaffold release-outcome-ledger suite

Compiles a non-executing owner-gated release-outcome-ledger suite from release-execution-evidence packets or nested release-execution-evidence inputs plus owner-supplied release outcome archive, final state, summary, follow-up, customer-impact, stability-window, and rollback/incident closeout refs. The response exposes per-workstream outcome ledger checklists, blockers, evidence status, result classifications, and next actions while keeping ledger write by helper, archive publication by helper, evidence recording by helper, release execution start, release decision execution, release executor dispatch, PR merge, owner release approval by helper, production release, production smoke execution, and docs/public discovery mutation disabled. This preview writes no records and cannot execute implementation, run production smoke, release production, publish public discovery, mutate routes, mutate Seller OS, mutate trust/ranking, activate or mutate x402, move wallets, settle, dispatch providers, run browser automation, write or promote memory, perform live finance actions, or expose private Full ECF payloads.
