feat(designbook): technology-neutral IR + stack-adapter pipeline (WHYNOT-WP-0002 T01-T06)

Author the design language once in the canonical React designbook and project it one-way onto each stack: React -> designbook/ -> ir/ -> adapters/<stack>/. Phase 0 — contracts & governance (T01-T03): - ir/SCHEMA.md + ir/schema/{component,tokens}.schema.json — neutral IR contract (W3C DTCG tokens; React prop -> HTML attribute mapping; non-portable props flagged). - adapters/ADAPTER_CONTRACT.md — inputs, drift-report + parity-result shapes, idempotency rules, CI exit codes (0 ok / 2 usage / 3 drift / 4 parity / 5 internal). - .claude/rules/designbook-propagation.md + DesignSystemIntroduction.md §5.1 — one-way directionality + drift-resolution workflow. T04 — canonical React designbook + the missing pull tool: - The bundled /design-sync skill only PUSHES repo->cloud; it cannot populate designbook/. Added scripts/designbook_pull.py + `make designbook-pull`, which drives the local claude binary headless (acceptEdits) so DesignSync fetch+write runs in a subprocess (contents never hit the orchestrator's context). Pulled 44 files; excludes the _whynot-design-seed/ self-copy. Corrected the docs that wrongly called /design-sync the pull. T05 — IR extractor (scripts/ir-extract.mjs + `make ir`): - ir/tokens.json (80 tokens, DTCG, var() -> {ref} alias resolution); ir/components/*.json (10 contracts parsed from .jsx signatures: enum/boolean/number inference, prop->attr map, style/callback marked non-portable); ir/exemplars/*. T06 — Lit token adapter (adapters/lit/ + `make adapt-lit`): - Full-gen tokens into src/styles/colors_and_type.css :root (marker-bounded, idempotent no-op on re-run; hand-authored type CSS preserved). NOTE: token regen synced Lit to canonical React — fonts IBM Plex -> system stacks and 8 status tokens added. This is a VISUAL change: review and run `pnpm test:visual:update` before merge. Remaining: T07 scaffold+drift, T08 parity, T09 runbook, T10 2nd-adapter. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

+# Decision: the canonical React designbook (WHYNOT-WP-0002 · T04)
+
+> **Status: RESOLVED.** The canonical React designbook **already exists** — it is
+> the **"WhyNot Design System"** project in Claude Design
+> (`fb2eef8c-c1fc-4c75-bff4-3782552e5511`, owner Bernd). The remaining concrete
+> action is the first `/design-sync` pull into `designbook/`.
+
+## Correction to the earlier premise
+
+An earlier draft of this doc assumed the Claude Design project held only the
+hand-authored **Lit** experiment, and therefore proposed *authoring* a new React
+designbook. That premise was wrong. Inspecting the project
+(`DesignSync.list_files` / `get_file`) shows it already contains a real React
+source:
+
+- `ui_kits/whynot-control/*.jsx` — **React function components**: `Atoms.jsx`
+  (`Eyebrow`, `Tag`, `Button`, `StageDot`, `Stamp`, `Icon`), `Chrome.jsx`,
+  `Screens.jsx`, `DocView.jsx`, `data.jsx`. Props are expressed as JSX function
+  parameters with defaults (e.g. `Button({ variant = 'secondary', icon, … })`).
+- `preview/comp-*.html` — per-component preview cards (the exemplar renders).
+- `styles.css`, `colors_and_type.css`, `_ds_manifest.json`, `_ds_bundle.js` —
+  token/style layers + the grouping manifest.
+- `_whynot-design-seed/` — a full copy of this Lit repo that seeded the project.
+
+So Claude Design is genuinely canonical today, and `/design-sync` provides the
+React origin from which Lit (and any future stack) is generated. This is the
+directionality the workplan already assumes: **React → IR → stacks.**
+
+## Resolution
+
+- **Canonical source:** the existing "WhyNot Design System" Claude Design project.
+  No new designbook is authored; nothing is adopted from a foreign kit.
+- **How it reaches `designbook/`:** run **`make designbook-pull`**
+  (`scripts/designbook_pull.py`) — it drives the local `claude` binary headless
+  (`claude --print --permission-mode acceptEdits`) so the `DesignSync` fetch+write
+  happens in a subprocess, and stamps freshness on success. (The bundled
+  `/design-sync` skill goes the other way — it *pushes* repo→cloud — so it does not
+  populate `designbook/`.) **Done 2026-06-23:** 44 files pulled (the `.jsx` ui-kit,
+  `_ds_manifest.json`, style layers, and `preview/*.html` exemplars);
+  `_whynot-design-seed/**` excluded.
+
+## Consequence for the extractor (T05)
+
+The React source is a **bundled `.jsx` ui-kit** (several components per file),
+**not** the per-component `.d.ts` + `.prompt.md` layout the T01 schema notes
+assumed. The neutral IR **contract schema is unaffected** (it describes the
+*output* shape), but `scripts/ir-extract.mjs` (T05) must:
+
+- read component **props/defaults from the JSX function signatures** in
+  `ui_kits/whynot-control/*.jsx` (not `.d.ts`),
+- take **grouping** from `_ds_manifest.json`,
+- take **exemplars** from `preview/comp-*.html`,
+- take **tokens** from the project's `styles.css` / `colors_and_type.css` (and/or
+  the seed `tokens/*.json`), normalising to W3C DTCG.
+
+This is recorded so T05 is designed against the real source layout.
+
+## What unblocks the rest of the pipeline
+
+1. Run `/design-sync` → `designbook/` receives the React mirror (more than README).
+2. Stamp + `make designbook-sync`.
+3. `make ir` (T05) extracts the IR from the `.jsx` ui-kit + previews + manifest.
+4. T06–T08 (Lit adapter + parity) then run against real data.

+# whynot-control UI kit
+
+A click-through high-fidelity recreation of the `whynot-control` repository — rendered not as a folder of Markdown files, but as the lightweight web application it implies.
+
+This kit demonstrates the WhyNot Design System applied to its primary use case: a prototype-and-signal control surface. Everything here is **cosmetic** — there's no backend, no persistence, no real router. Each screen is a working visual artefact you can drop into a design review.
+
+## Screens
+
+| Screen | Source doc(s) | Component |
+|---|---|---|
+| Inbox | `inbox/` | `Inbox.jsx` |
+| Prototypes (index) | `prototypes/` + `PROTOTYPE_PIPELINE.md` | `PrototypesIndex.jsx` |
+| Prototype (detail) | `templates/prototype-card.md` + `example-prototype-card.md` | `PrototypeDetail.jsx` |
+| Signals | `signals/` + `MARKET_SIGNAL.md` | `SignalsIndex.jsx` |
+| Document viewer | `INTENT.md`, `OPERATING_MODEL.md` | `DocView.jsx` |
+
+## Components
+
+- `TopNav.jsx` — sticky 56px hairline top bar (search + new-idea action).
+- `Sidebar.jsx` — left rail with org slug, repo nav, activation indicator.
+- `PrototypeCard.jsx` — the card from `preview/comp-prototype-card.html`, factored.
+- `PipelineStrip.jsx` — the 5-stage progress strip from `preview/comp-pipeline.html`.
+- `SignalRow.jsx` — one row in the signals table.
+- `Tag.jsx`, `Eyebrow.jsx`, `Button.jsx`, `StageDot.jsx`, `Stamp.jsx` — atoms used everywhere.
+
+## Conventions
+
+- All components are flat function components, no hooks beyond `useState` for screen routing.
+- Components export themselves onto `window` so each `<script type="text/babel">` file can find them.
+- Style objects are inline or scoped (e.g. `cardStyles`, `navStyles`) to avoid name collisions.
+- Icons are Lucide via CDN, rendered as `<i data-lucide="…">` and hydrated by `lucide.createIcons()`.
