Changelog

Vidar the Patient — Master of Craft

In one breath

The changelog is the chronological spine of the book — every entry links back into the chapter that changed, so you can find the last date you read and follow the See: links directly into what changed since then.

By the end of this page you’ll know:

• How to use the changelog to catch up after time away
• Which chapters carry the ## What changed anchors that these See: links point to
• How new features are recorded here when they ship

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.

See it as

A library card catalogue, but organised by date instead of by subject. Each drawer (date entry) holds cards for everything that arrived that week. Each card has a reference number (the CAS ID) and points to the shelf where the full chapter lives. When you come back after a month away, you open the catalogue to where you left off and follow the cards — the chapters themselves stay exactly where they always were.

CAS-3792 — Authoring Conventions + Officer→Regent Deliverable Format {#cas-3792}

The Authoring Conventions page is now the second entry under “Start Here”. It catalogs the pattern library for Book chapter authoring — callouts, Mermaid, Tabs, collapsibles, Card grids, Steps, side-by-side tables, inline SVG, and the layered-detail pattern — with live worked examples for each. It also documents the audience-driven officer→regent deliverable convention (HTML for human-review-heavy artifacts; markdown for AI↔AI and routine artifacts), the PR explainer pattern, and the hard constraint against over-proceduralizing the pattern library. AGENTS.md adds a matching §7 deliverable-format section that agents can read without loading the full Book.

CAS-3757 — Curated Reading Path {#cas-3757}

The flat 70-document Features dump replaced with ten named, ordered sections following the conceptual arc: The Ledger → Security Foundation → Your Devices → Mobile → Providers → AI Features → The Feedback Loop → Quality Engineering → UX System → Testing Infrastructure → Appendix. The Path spine page explains the ordering rationale.

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.

See: Provider Plugins → What changed

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.

CAS-3096 — Paperclip API Launchd Self-Heal {#cas-3096}

CAS-748 — Sync Relay (Cross-Device Sync) {#cas-748}

Initial sync relay deployed. Devices now exchange encrypted changesets through the relay. See the Architecture → Sync and Security chapter for the full design.
