required_canon_version: >=3.0.0

Skill: Invariant Freeze

Version: 0.1.0 Status: Active

Purpose

Verifies that all core invariants (INV-001 through INV-008) exist in CANON/INVARIANTS.md. This ensures that invariants are not removed without a major version bump, maintaining the v1.0 stability guarantee.

Triggers

• Manual verification of governance stability.
• CI check before releases.

Inputs

• CANON/INVARIANTS.md (source of truth)
• input.json with expected_invariants list.

Outputs

• actual.json with:
  • found_invariants: list of matches.
  • missing: list of missing expected invariants.
  • valid: boolean status.

Constraints

• Must search for exact [INV-XXX] tags.
• Must not allow gaps or removals from the frozen list.
