Module: Ai2Web::Validator

Defined in:
lib/ai2web/validator.rb

Overview

AI2Web validation + AI Readiness scoring.

Port of @ai2web/core validateManifest (spec sections 9 & 11). MUST stay in exact parity with the TypeScript reference and ai2web-spec/conformance/cases.json.

validate returns a Hash:

{ valid: Boolean, errors: [String], checks: [{ ok:, points:, label:, hint: }],
score: Integer (0..100), tier: "Invalid"|"Basic"|"Standard"|"Enterprise" }
