Cryptographic Signatures

Every approval is cryptographically signed using SHA-256 hashing. We capture IP addresses, user agents, and timestamps to create a verifiable signature that cannot be forged or disputed.

  • SHA-256 cryptographic hashing for every signature
  • IP address and user agent capture for verification
  • Typed name attestation with explicit agreement statement
  • Tamper-proof signature records stored permanently

Immutability

Immutable Versions

Once a scope version is approved, it becomes permanently locked. No edits, no deletions, no backtracking. Every change requires a new proposal and unanimous approval.

  • Versions locked forever after full approval
  • All changes go through explicit proposal workflow
  • Complete version history preserved indefinitely
  • Zero risk of retroactive modifications or disputes
Determinism

Canonical Diffs

Every proposal automatically generates a deterministic diff showing exactly what changed from the previous version. Diffs are computed once and never recomputed, ensuring consistency.

  • Automatic diff generation on proposal submission
  • Zero-variance canonical snapshots with SHA-256 hashing
  • Deterministic change IDs for every modification
  • Diffs computed once, never recomputed or altered

Unanimous Approval

All designated project leaders must explicitly sign. No shortcuts, no auto-approvals. Complete transparency for both parties.

  • Explicit sign-off required from all parties
  • Real-time approval status tracking

Append-Only Audit Log

Complete audit trail of every action. Events are never deleted or modified. Full traceability for compliance and dispute resolution.

  • Immutable event log with timestamps
  • Complete history of all project activity

Export Everything

Generate PDF, DOCX, or XLSX exports with complete version history, signatures, and audit trails. Always have proof.

  • Multiple export formats available
  • Includes all signatures and timestamps

Comments & Discussions

Built-in commenting system for sections and items. Have contextual discussions right where they matter most.

  • Thread-based discussions on any scope item
  • Real-time notifications and updates

Complete Version History

Every version is preserved with full context. See exactly what was agreed to at any point in time.

  • Browse any historical version
  • Compare versions side-by-side

Proposal Snapshots

Before signing, reviewers see the exact canonical snapshot they're approving. No surprises.

  • Crystal-clear view of what's being signed
  • Canonical representation of all terms
