Changelog

The changelog is the spine of the book. Every entry links back into the chapter that was updated, so you can read forward in time and jump directly to what changed.

How to use it: find the last date you read. Follow the See: links into the chapters that changed since then.

CAS-3645 — The Casaconomy Book (Phase 3) {#cas-3645}

All existing docs migrated into the book. Every architecture chapter now carries Starlight frontmatter, a persona byline, and a #what-changed anchor. The 67 feature docs are indexed in the sidebar. The changelog is now the wired chronological spine — every entry deep-links into the chapter that changed.

CAS-3639 — The Casaconomy Book (Phase 2) {#cas-3639}

Starlight scaffold and the first full sample chapter shipped. The canonical chapter skeleton — persona byline, in one breath, learning objectives, body, see it as, worked example, recap, and #what-changed anchor — is now the authoring contract for every new chapter.

CAS-3499 — Declarative CF Provider Plugins {#cas-3499}

Provider plugins are now downloadable from Cloudflare R2 and interpreted by the existing plugin engine without a code deploy. Plugins define their schema, OAuth flows, and sync logic in a single manifest file. The full catalog UI is live in Settings.

CAS-3605 — Fake Provider Harness {#cas-3605}

An end-to-end test harness for provider sync using a local Miniflare worker (wrangler dev --local on :8791). Provider engineers can now verify their plugin manifests against a live provider contract without touching production Cloudflare infrastructure.
