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>

# `ir/` — technology-neutral design blueprint
This directory holds the **intermediate representation (IR)** of the whynot design
language: tokens, per-component contracts, and reference exemplars, in a form that
carries no framework assumptions.
## Decision: `ir/` is committed
`ir/` is **checked into git**, on purpose. The IR is the diffable blueprint of the
shared language — committing it means a re-extract (`make ir`) surfaces every
blueprint change as a reviewable git diff, and adapters have a stable, versioned
input. It is a build *input*, not a throwaway build *output*.
What is committed:
- `tokens.json` — all tokens, W3C DTCG format.
- `components/<Name>.json` — one contract per component.
- `exemplars/<Name>.{png,html}` — reference renders from the designbook preview.
- `schema/` + `SCHEMA.md` — the contract definitions (this is what T01 delivered).
## Direction of flow
```
Claude Design (React) ──/design-sync──▶ designbook/ ──make ir──▶ ir/ ──make adapt-lit──▶ adapters/lit/
```
One-way. The only writer of `tokens.json`, `components/`, and `exemplars/` is the
extractor (`scripts/ir-extract.mjs`, T05). **Do not hand-edit those** — change the
language in Claude Design and re-propagate. The `schema/` files and these docs are
the exception: they are authored here.
See [`SCHEMA.md`](./SCHEMA.md) for the full contract spec and a worked `Button`
exemplar.
