Version history

Version 1.0 — Initial release

Establishes the structural framework covering pricing, process, and integrity.

• 2026-05-17 — Added root-level llms.txt reference file.
• 2026-07-24 — Updated llms.txt to LLMS Baseline v3.1. The file now follows the frozen canonical Markdown structure with machine-readable navigation across all published reference resources.
• 2026-09-27 — Removed the email property from Organization JSON-LD across all 13 published HTML pages to align the implementation with the established portfolio governance baseline. Frontend contact information remains unchanged. No change to the site’s semantic definition, scope, 13-page structural baseline, review mechanism, source architecture, or existing JSON-LD architecture.
