## What this deliverable contains

This directory mirrors the `a11oy/packages/policy/src/gates/` target structure and provides
the 30 new policy gate files that extend a11oy#108 (`cursor/policy-gates-hardening-2f18`).

## TL;DR

**Gate files written:** 30 new gate files + 1 updated barrel `index.ts` = 31 files total.
The barrel also re-exports the 5 original gates from a11oy#108, for a complete 35-gate surface.

**Tests written:** 90 Vitest-compatible assertions in `policy_gates_extended.test.ts`
(3 per new gate: positive/allow, negative/deny, edge/boundary or throws-on-invalid-input).
The existing `policy_gates.test.ts` from a11oy#108 covers the original 5 gates.
Combined test surface: 90 + existing = complete gate coverage.

**Lean status breakdown (30 new gates):**
- Theorem (0 sorry in gate's own Lean file): 20 gates — A1–A6, A8–A9, A10–A12, A14, T1–T3, T5–T10, TH1–TH3, TH6–TH7, TH_L4
- Conjectured (pending Lean formalization): 4 gates — A7, T4, TH4, TH5
- Measured/empirical: 1 gate — TH_L4 (ρ-closure 100% on 8,000 calls, ouroboros v6.3.0)
- Measured/conjectured: 1 gate — TH_L3 (49.5% fire rate, pending PR #12)
- Theorem with 2 sorrys in wider Lean repo (not in gate file itself): 2 gates — TH_L1, TH_L2

**STAGED advisory labels applied to 4 gates:**

| Gate | Formula ID | Reason |
|---|---|---|
| `bekensteinBound_gate.ts` | A7 | conjectured; TH6 DPI formally discharges it but gate-level Lean file pending |
| `lambdaCategoryComposability_gate.ts` | TH4 | pending `Lutar/LaxFunctor.lean` |
| `bekensteinSoundness_gate.ts` | TH_L3 | pending `lutar-lean` PR #12 |
| `liuHuiPi_gate.ts` (a11oy#108) | Liu Hui | axiom-structured — advisory by original design |

These 4 gates default to `enforced: false` and emit `severity: 'warning'`.
Pass `{ enforced: true }` to promote any gate to blocking.

**How to wire to a11oy#108:**

```bash
# Inside the szl-holdings/a11oy repo, on branch cursor/policy-gates-hardening-2f18:
cp /home/user/workspace/szl/audit_2026-05-29_evening/formula_gates_30/packages/policy/src/gates/*_gate.ts \

# Run the full gate test suite
pnpm vitest run packages/policy/src/gates/__tests__/

# Commit with sign-off (Doctrine v6)
git add packages/policy/
git commit -s -m "feat(policy): add 30 anchor formula gates (A1-A14, T1-T10, TH1-TH7, TH_L1-TH_L4)"
```

**Pattern conformance:** Every gate file matches the `adversarialRobustness_gate.ts` pattern from a11oy#108:
- SPDX + ORCID header
- Named `export function <camelCase>Gate(config)(opts): Decision`
- JSDoc citing Lean theorem name, file, and commit SHA
- `leanCommitSha`, `rationale` (with `Lean:` reference), and `leanFile` in every return value
- TypeScript-strict (no `any` types)
- Under 120 lines per file
- Inline formula comment block
