Preview a non-executing External Source Scaffold production hardening audit suite

Compiles a non-executing owner-gated production hardening audit suite from canary, production-readiness, activation-plan, activation approval, and implementation-packet inputs for all External Source Scaffold Program workstreams. The response exposes per-workstream phase evidence, gate blockers, release blockers, validation plans, rollback paths, and exact next actions while keeping implementation execution, production release, and production smoke execution 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.
