# @szl-holdings/a11oy-policy

A11oy policy loader and Layer 6 formula gates.

## What is real today

- `policy_loader.ts` loads vertical governance policy YAML, validates it
  structurally and semantically, and emits a policy-load receipt.
- `src/gates/` exposes five executable Layer 6 formula gates:
  - `adversarialRobustnessGate`
  - `falsePositionGate`
  - `liuHuiPiGate`
  - `madhavaBoundGate`
  - `summationInvariantGate`
- `src/contracts/` emits receipt-backed controls, action-contract, and
  autonomous-learning proposal/evaluation/human-promotion envelopes.
- `npm test --prefix packages/policy` runs all gate and contract receipt tests.

## What this is not

- Not a claim that every Lean theorem is closed.
- Not a replacement for `web/packages/a11oy-core`; this package is the policy
  boundary and formula-gate surface.
- Not a cryptographic signer. Receipts produced by the policy loader are local
  integrity records unless downstream signing is wired in.
- Not a cryptographic human-identity verifier. Human-promotion receipts bind
  declared reviewer fields; external identity proof requires a separate signer
  verifier.
- Not autonomous production promotion. Autonomous-learning helpers can emit and
  verify proposal/evaluation/promotion receipts, but deployment/publication
  still requires CI evidence and named human promotion.
