Specification Freeze — Forensic Provenance Protocol (FPP)

Version

v0.1

Freeze Date

2026-01-10

Status

FROZEN

Scope of Freeze

This file declares a formal specification freeze for Forensic Provenance Protocol (FPP) v0.1.

The following documents are hereby frozen and normative:

  • PROTOCOL.md
  • INVARIANTS.md
  • THREAT_MODEL.md
  • CONFIDENCE_MODEL.md
  • ATTRIBUTION_BOUNDARY.md

These documents collectively define the complete and authoritative v0.1 protocol specification.


Post-Freeze Rules

Effective immediately upon this freeze:

  • No semantic changes are permitted to frozen documents
  • No invariants may be weakened or removed
  • No attribution, identity inference, or ownership claims may be introduced
  • No heuristic or probabilistic guessing may be added
  • All future changes must be versioned (v0.2, v1.0, etc.)

Clarifications, commentary, or errata may only be added via:

  • New documents, or
  • Explicit versioned amendments

Implementation Policy

  • Reference implementations MUST conform to the frozen specification
  • Implementations MAY be incomplete
  • Implementations MUST NOT extend protocol semantics
  • Any divergence MUST be documented explicitly

Intent

This freeze exists to:

  • Preserve determinism and reproducibility
  • Prevent scope creep
  • Enable independent implementation
  • Establish audit and review stability

This freeze does not imply:

  • Production readiness
  • Completeness of implementation
  • End of research or future versions

Authority

This freeze is declared by the protocol author and is binding for v0.1.

Subsequent protocol evolution requires a new versioned freeze.
