@zanii/walls

UAE vertical "wall" presets as enforceable, auditable artifacts. A wall = a scope the delegation never grants + a policy that denies the risky action + a manifest_hash you receipt per deploy (so the enforced rulebook is provably unaltered, not just the prose).

Flagship: SCA trading — "education only, NEVER 'buy this'", the most sensitive vertical (investment advice/execution is a licensed activity). Plus RERA (realty), TDRA (messaging), Legal, Consumer/collections, and DIFC/ADGM free-zone data-protection variants (which differ from federal PDPL).

npm install @zanii/walls @zanii/policy @zanii/core

Usage

import { WALLS, wallPolicy, wallManifestHash, checkOutput, buildEvalReceipt } from '@zanii/walls';
import { createPolicyEngine } from '@zanii/policy';

const wall = WALLS['sca-trading'];

// 1. enforce the wall (deny what it forbids):
const engine = createPolicyEngine(wallPolicy(wall));
engine.evaluate({ target: 'trading.execute.order' }).decision; // 'deny'

// 2. anchor the enforced rulebook — receipt this per deploy:
const manifestHash = wallManifestHash(wall);

// 3. catch a crossing at output time + receipt the eval suite:
checkOutput(wall, 'You should buy this now').ok;            // false — flagged
await agent.record(buildEvalReceipt(wall, { passed: 23, failed: 0 }));

checkOutput is a heuristic (phrase match) — a published, auditable first line; swap in a classifier for higher assurance. wallManifestHash is order-independent (stable across deploys).

Changelog

• 0.1.0 — initial release: WALLS (sca-trading, rera, tdra, legal, consumer, difc, adgm), wallPolicy, wallManifestHash, checkOutput, buildEvalReceipt.
