Changes: Refresh the environment-access result and document S00-020 restoration, accepted prerequisites and independent QA handoff; preserve probe code and parent dependency graph.
Validation: verify.py passed official HTTPS vendor checksum, Node 24.21.0/npm 11.19.0, fresh-cache strict npm ci and Stanza import. Separate artifact/input/version/strict-setting assertions and tasks.py validate passed. No browser/WSS or product readiness check performed.

Changes: Preserve incomplete work and blocker metadata for S00-020. This checkpoint does not mark implementation accepted.
Validation: Session ended with status blocked.
Blocker: Previous runner session was interrupted before submit/escalate; processes stopped. User now explicitly requests resuming development. Preserve partial artifacts, verify them in a fresh bounded remediation, and return original to a new executor only after independent review.
