Methodology

A statute, code, constitutional provision, decree, regulation, or national policy that establishes or governs the right to education or the structure of the education system in a jurisdiction. Secondary commentary is catalogued only as a discovery aid, never as the law itself.

Every URL carries a status and a last-checked timestamp. The checker validates the URL against an SSRF guard, tries HEAD then GET, follows up to five redirects, and never bypasses paywalls, CAPTCHAs, robots rules, or authentication.

Records move draft → submitted → under_review → verified → published → needs_recheck → archived. A record is only shown as verified after a reviewer confirms the citation against the primary text. Seed/demo rows are flagged and are never presented as verified law.

The original-language title is always shown. English/Thai titles are labelled unofficial unless an official translation exists. Only the official text on the competent authority's source has legal effect.

Completeness of metadata, tier of source, authoritativeness of the linked copy, freshness of the last link check, and reviewer sign-off together determine a record's confidence.
