Checksums, timestamps, and seals
SHA-256 manifests, OpenTimestamps Bitcoin anchors (blocks 959483–960086), annotated tags and releases.
Phase 5 seal recordPhase 4 seal recordReleases
Every registry seal and close-out is hash-manifested and externally anchored: tags phase4-v3-seal, phase4-final, phase5-v4-seal, phase5-final, and paper-text-freeze-v10, each with a GitHub release timestamp and OpenTimestamps proofs upgraded to complete Bitcoin attestations. The registered language is deliberate: records are externally anchored, not “cryptographically immutable,” and no GPG signature exists (a disclosed plan deviation).
