CHANGELOG.md

v0.2.0 — Ledger Era + Canonical API Base

Breaking

• API base is now https://api.thehumanpatternlab.com.
• Removed /api path prefix from canonical routes.
  • Example: /lab-notes (new) instead of /api/lab-notes (old).
• Main site legacy /api/* routes are deprecated and redirect to the API subdomain.

Database

• Refactored persistence to the Ledger model.
  • Ledger becomes the canonical source of truth for note storage and mutation history.
  • Improves auditability and enables future CLI automation workflows.

Notes API

• Lab Notes endpoints continue to support list + detail retrieval while backed by the Ledger model.
• Response shape remains compatible with existing UI normalization (fields unchanged unless noted).

Ops / Deployment

• Production routing standardized: website on thehumanpatternlab.com, API on api.thehumanpatternlab.com.
• Reduced ambiguity between static site routes and API routes.
