PR #18 was left branch-identical to main after a misapplied revert removed the four authorised new files. This PR restores exactly those files — no modifications to any existing file.

Restored files (new, stdlib-only)

  • mgtp/__init__.py — package marker
  • mgtp/decision_space.py — deterministic snapshot validator, canonicaliser, SHA-256 hasher, and structural differ for decision_space_snapshot_v1 JSON
  • scripts/ds_diff.py — thin CLI wrapper: loads two snapshots, validates, prints hashes + JSON diff
  • tests/test_decision_space.py — 46 tests covering validation, canonicalisation, hash stability/determinism, and diff correctness

What's untouched

commit_gate/, authority_gate.py, stop_machine.py, .github/workflows/ — zero diff vs main.

Snapshot schema (v1)

{
  "version": "v1",
  "variables": [str],
  "allowed_transitions": [{"from": str, "to": str}],
  "exclusions": [str],
  "reason_code_families": {str: [str]}
}

diff_snapshots(a, b) returns added/removed sets for each field; snapshot_hash is order-independent (canonicalises before hashing).
