gatecheck

Policy gate evaluation over evidence snapshots and receipts.

gatecheck is the neutral gate evaluator for governed change. It reads a checked-in policy, evaluates it against a deterministic evidence snapshot, and emits a stable gate report plus a human-readable summary.

It is deliberately not the spec pipeline, not the diff linter, and not the merge cockpit. It sits between evidence producers and the merge surface.

What it is

• policy + evidence snapshot → gate report
• local-first, deterministic, schema-shaped artifacts
• hexagonal workspace: pure evaluation core, adapters at the edge
• focused microcrates with one responsibility each
• BDD-style tests that document observable behavior
