+# Credential and access routing
+
+**Audience:** Codex, Claude Code, Grok, and custodian agents that call **llm-connect**
+for inference. Run this check **before** requesting secrets, API keys, SSH access,
+login tokens, or database passwords — in any repo, not only `ops-warden`.
+
+ops-warden **issues SSH certificates only** (`warden sign`, `cert_command`). Every
+other credential need belongs to another subsystem. **Do not** message
+`ops-warden` on State Hub expecting a secret value; the reply is a pointer, not a key.
+
+### Lookup (do this first)
+
+```bash
+warden route find "<describe your need>" --json
+warden route show <catalog-id> --json
+```
+
+Requires the `warden` CLI from `~/ops-warden` (`uv tool install .` or `uv run warden`).
+
+| Agent runtime | How to orient |
+| --- | --- |
+| **Codex / Grok** (shell, HTTP State Hub) | `warden route` commands above; inbox `to_agent=whynot-design` is for coordination, not secret vending |
+| **Claude Code** (MCP when available) | `get_domain_summary("custodian")` for workstreams; **still** use `warden route` for credential ownership |
+| **llm-connect** (inference service) | Never put secret retrieval in prompts; route custody to OpenBao/operator paths surfaced by `warden route` |
+
+### Quick routing table
+
+| I need… | Owner | ops-warden executes? |
+| --- | --- | --- |
+| SSH cert (`adm`/`agt`/`atm`) | ops-warden | **Yes** — `warden sign` |
+| API key, DB password, provider token | OpenBao (`railiance-platform`) | No — route only |
+| Login / OIDC / MFA | key-cape / Keycloak | No — route only |
+| Authorization decision | flex-auth | No — route only |
+| activity-core → issue-core emission | activity-core + issue-core | No — `warden route show activity-core-issue-sink` |
+| SSH tunnel | ops-bridge (+ `cert_command` from warden) | No — route only |
+
+### Anti-patterns (do not do these)
+
+- `POST /messages/` to `ops-warden` asking for `ISSUE_CORE_API_KEY`, `OPENROUTER_API_KEY`, etc.
+- Inventing `warden secret`, `warden login`, `warden bao`, `warden tunnel` — they do not exist
+- Pasting secrets into Git, State Hub, workplans, logs, or chat
+
+### Other capabilities (reuse-surface)
+
+Non-credential capabilities are usually discovered through **reuse-surface** federation
+(`reuse-surface` registry / `capability.*` indexes). Credential routing is inlined in
+every repo's agent instructions because it is high-frequency, high-risk, and easy to
+get wrong.

+## Designbook propagation & adapter governance (WHYNOT-WP-0002)
+
+The whynot design language is **technology-neutral**. It is authored once and
+projected onto each UI stack through an intermediate representation. These rules
+keep that flow one-way and the stacks in sync.
+
+### Directionality — one way only
+
+```
+Claude Design (React, canonical)  →  designbook/  →  ir/  →  adapters/<stack>/ → stack source
+```
+
+- **Claude Design (the React designbook) is the source of truth** for the *language*.
+- **Never hand-edit `ir/`** — `ir/tokens.json`, `ir/components/*.json`, and
+  `ir/exemplars/*` are written only by the extractor (`scripts/ir-extract.mjs`,
+  `make ir`). They are committed so blueprint changes show up as a git diff.
+  Authored-by-hand exceptions: `ir/schema/`, `ir/SCHEMA.md`, `ir/README.md`.
+- **Never back-edit React/Claude Design from a stack.** A Lit (or any stack) change
+  that should alter the shared language must be made in Claude Design and
+  re-propagated. A direct stack→React edit that bypasses Claude Design is a
+  governance violation — it desyncs the canonical source from the implementation.
+- **Adapters never overwrite hand-authored behaviour.** Tokens regenerate fully;
+  new components get stubs; changed components get a **drift report**, never a
+  rewrite. See `adapters/ADAPTER_CONTRACT.md`.
+
+### When the cloud designbook moves
+
+Run the refresh sequence (orchestrated by `make designbook-refresh`, WHYNOT-WP-0002
+Phase 5); do not shortcut it:
+
+1. `make designbook-check` — detect the cloud designbook moved ahead.
+2. `make designbook-pull` — pull the latest React designbook into `designbook/`
+   (drives the local `claude` binary headless via `DesignSync`; stamps freshness
+   itself). The bundled `/design-sync` skill *pushes* repo→cloud and does **not**
+   populate `designbook/` — use `make designbook-pull` for the pull.
+3. `make designbook-sync` — record the diff in `RecentChanges.md`.
+4. `make ir` — re-extract the IR; **review the `ir/` git diff** (the blueprint change).
+5. `make adapt-lit` — regenerate tokens, scaffold new components, emit drift reports.
+6. **Resolve drift** (human) — fill/adjust Lit behaviour per `adapters/lit/drift/*.md`.
+7. `make parity-lit` — confirm appearance + contract parity (gate).
+
+### Drift triage
+
+A drift report (`adapters/lit/drift/<Name>.md`, command exit code `3`) is resolved
+by a human, not the adapter:
+
+- Decide direction: stale stack → fix the stack to match IR; language should change
+  → edit Claude Design and re-propagate (never patch only the stack).
+- **Non-portable props** (React objects, render props, callbacks) are surfaced as
+  drift on purpose and must be handled explicitly — never silently dropped.
+- A report is closed when a fresh `make ir && make adapt-lit` produces no issues
+  for that component and `make parity-lit` passes (exit `0`).
+
+### Exit codes (CI)
+
+`0` ok · `2` usage/config error · `3` drift detected (stop for human triage) ·
+`4` parity failure (fail) · `5` internal error. See `adapters/ADAPTER_CONTRACT.md`.

+## Session Protocol
+
+Dev Hub (State Hub API): http://127.0.0.1:8000
+MCP server name in `~/.claude.json`: `dev-hub`
+
+**Step 1 — Orient**
+
+Read the offline-safe brief first — it works without a live hub connection:
+```bash
+cat .custodian-brief.md
+```
+Then call the MCP tool for richer cross-domain context when MCP tools are exposed:
+```
+get_domain_summary("consumer")
+```
+If MCP tools are unavailable in the current agent session, use the REST API:
+```bash
+curl -s "http://127.0.0.1:8000/state/summary" | python3 -m json.tool
+```
+If the hub is offline: `cd ~/state-hub && make api`
+
+**Step 2 — Check inbox**
+With MCP tools:
+```
+get_messages(to_agent="whynot-design", unread_only=True)
+```
+Mark read with `mark_message_read(message_id)`. Reply or act on coordination
+requests before proceeding.
+
+Without MCP tools:
+```bash
+curl -s "http://127.0.0.1:8000/messages/?to_agent=whynot-design&unread_only=true" \
+  | python3 -m json.tool
+curl -s -X PATCH "http://127.0.0.1:8000/messages/<id>/read" \
+  -H "Content-Type: application/json" -d '{}'
+```
+
+**Step 3 — Scan workplans**
+```bash
+ls workplans/
+```
+For each file with `status: ready`, `active`, or `blocked`, note pending
+`wait`/`todo`/`progress` tasks.
+
+**Step 4 — Present brief**
+
+1. **Active workstreams** for `consumer` — title, task counts, blocking decisions
+2. **Pending tasks** from `workplans/` + any `[repo:whynot-design]` hub tasks
+3. **Goal guidance** — if `goal_guidance` in summary:
+   - `needs_workplan`: surface as top action — *"Repo goal '{title}' has no workplan yet"*
+   - `alignment_warnings`: flag if active work is not aligned with current goal
+4. **Suggested next action** — highest-priority open item
+5. **SBOM status** — flag if `last_sbom_at` is unset for this repo
+
+If no workstreams: follow First Session Protocol (`first-session.md`).
+
+**During work:** `record_decision()` · `add_progress_event()` · `resolve_decision()`
+
+> State Hub is a *read model*. Bootstrap tools (`create_workstream`, `create_task`)
+> are First Session Protocol only. Work structure belongs in repo files (ADR-001).
+
+**Session close:**
+With MCP tools:
+```
+add_progress_event(summary="...", topic_id="cee7bedf-2b48-46ef-8601-006474f2ad7a", workstream_id="<uuid>")
+```
+Without MCP tools:
+```bash
+curl -s -X POST http://127.0.0.1:8000/progress/ \
+  -H "Content-Type: application/json" \
+  -d '{"topic_id":"cee7bedf-2b48-46ef-8601-006474f2ad7a","workstream_id":"<uuid>","event_type":"note","summary":"what changed","author":"codex"}'
+```
+If workplan files were modified, ensure the local copy is up to date first:
+```bash
+git -C <repo_path> pull --ff-only
+cd ~/state-hub && make fix-consistency REPO=whynot-design
+```
+For repos where implementation runs on a remote machine (e.g. CoulombCore),
+use the combined target which pulls before fixing:
+```bash
+cd ~/state-hub && make fix-consistency-remote REPO=whynot-design
+```
+**C-15** (DB task ahead of file) is normal in multi-machine workflows — writeback
+will sync the file to match DB.  **C-16** (repo behind remote) blocks all writes
+until you pull — intentional to prevent clobbering remote progress.

+- **Key deps:** `lit` ^3 (web components, the one runtime dep); `@playwright/test` (the one dev dep, visual regression).
+- **Components:** shadow-DOM Lit elements that adopt a shared stylesheet so the Layer 1 `.wn-*` utility classes work inside the shadow root. `src/elements/_styles.js` is **auto-generated** from `src/styles/components.css` by `scripts/sync-shared-styles.mjs` — never hand-edit it.

+```
+
+### Keeping Lit current with the designbook — the refresh loop (WHYNOT-WP-0002)
+
+`make designbook-refresh` is the single routine that re-propagates a cloud designbook
+change down to the Lit stack. It runs the automatable steps and **stops for you** when
+drift needs a human decision:
+
+```
+1 designbook-check  → has the cloud moved?            (best-effort: needs llm-connect)
+2 designbook-pull   → pull React designbook→designbook/ (best-effort: needs `claude` binary)
+3 designbook-sync   → record the diff → RecentChanges.md
+4 ir                → re-extract ir/ (review the git diff — the blueprint change)
+5 adapt-lit         → regen tokens, scaffold new stubs, emit drift reports
+6 ‹you› resolve drift  ← STOP if step 5 exits 3 (adapters/lit/drift/*.md)
+7 parity-lit        → confirm contract + visual parity
+```
+
+Exit codes propagate the adapter contract: **3** = stop for drift triage (step 6),
+**4** = parity failure. Steps 1–3 are best-effort (a network/`claude`/llm-connect
+gap warns and continues; the IR just re-extracts from the current mirror). After
+resolving drift, re-run `make designbook-refresh --no-pull` (via `ARGS=`) to re-check
+and reach parity. Drift resolution itself is governed by
+`.claude/rules/designbook-propagation.md` (fix the stack, or change the language in
+Claude Design and re-propagate — never a stack→React back-edit).
+
+There is no unit-test suite — correctness is verified by full-page Playwright screenshot diffs of the two `examples/` pages (`tests/visual/ui-kit.spec.mjs`, `maxDiffPixelRatio: 0.005`). Any visual change needs `pnpm test:visual:update` + baseline review.
+
+## Integrating the designbook
+
+The **designbook** is the upstream atelier — the **Claude Design project** (cloud, `claude.ai/design`), source of truth for the *language*. Its local mirror lives in-repo at `designbook/` (see `designbook/README.md`). Sync is **agent-driven and incremental** (one component at a time, never a wholesale replace):
+
+1. **Pull** — run `make designbook-pull` (`scripts/designbook_pull.py`). It drives the local `claude` binary headless (`claude --print --permission-mode acceptEdits`), which has the `DesignSync` tool over the claude.ai login, to fetch the React designbook and write it into `designbook/`; the file contents stay in that subprocess, so the pull is cheap regardless of size. Selection is governed by `designbook/.design-pull.json` (it excludes `_whynot-design-seed/**`, the cloud project's copy of this repo). The script stamps freshness itself on success. **Note:** the bundled `/design-sync` skill goes the *other* way — it *pushes* a repo up to Claude Design — so it does **not** populate `designbook/`; use `make designbook-pull` for the pull (see `designbook-propagation.md`).
+2. **Record** — `make designbook-sync` runs `scripts/designbook-sync.mjs`, writing `RecentChanges.md`: a **snapshot** (not a log) of what changed across `designbook/` + the derived surfaces (`tokens/`, `src/styles/`, `src/elements/`, `examples/`), grouped by layer.
+
+**Freshness** is tracked in `designbook/.design-sync.json` (`lastSyncAt`, `remoteUpdatedAt`, `projectId`, `projectName`). Every report states **"Last /design-sync: <datetime>"** so it's clear whether the snapshot reflects the latest design. The cloud-ahead check is backed by **llm-connect** (`make designbook-check` → `scripts/check_designbook_staleness.py`): it uses the `claude-code` adapter to ask the local `claude` binary for the project's current `updatedAt` via `DesignSync.list_projects`, then records it with `node scripts/designbook-sync.mjs --remote-updated <iso>`. Only the `claude-code` adapter can reach the user's Claude Design project (Gemini/OpenRouter/OpenAI cannot), and no secret goes in the prompt — DesignSync uses the claude.ai login (see `credential-routing.md`). The check needs `llm_connect` importable; the Makefile auto-selects `~/llm-connect/.venv/bin/python`. Use `--remote-updated <iso>` to run the comparison offline/manually, or `--fail-if-stale` (exit 3) in automation. When `remoteUpdatedAt` is newer than `lastSyncAt`, the report and stdout **warn that the local mirror is OUTDATED** until the next `/design-sync`. If no sync was ever recorded, it warns that `/design-sync` has not run. The reporter is deterministic (built from `git status`/`git diff`), only writes the working tree, never commits, and never edits `designbook/` content. Fold notable entries into `CHANGELOG.md` under `## [Unreleased]` before releasing — `RecentChanges.md` is overwritten every run and is **not** the CI-enforced artifact.

+## Workplan Convention (ADR-001)
+
+File location: `workplans/WHYNOT-WP-NNNN-<slug>.md`
+ID prefix: `WHYNOT-WP-`
+
+Work items originate as files in this repo **before** being registered in the hub.
+
+Canonical workplan/workstream frontmatter statuses are:
+`proposed`, `ready`, `active`, `blocked`, `backlog`, `finished`, `archived`.
+Use `proposed` for a newly drafted plan, `ready` after review against current
+repo state, and `finished` when implementation is complete. `stalled` and
+`needs_review` are derived health labels, not stored statuses.
+
+Closed workplans may be moved to `workplans/archived/` with a completion-date
+prefix: `YYMMDD-WHYNOT-WP-NNNN-<slug>.md`. The frontmatter id remains
+unchanged; the prefix is only for quick visual reference.
+
+Small opportunistic tasks discovered during another session use **Ad Hoc Tasks**:
+`workplans/ADHOC-YYYY-MM-DD.md`, workstream slug `adhoc-YYYY-MM-DD`, and task ids
+`ADHOC-YYYY-MM-DD-T01`, `T02`, etc. Use adhocs only for low-risk work completed
+directly. Promote anything requiring analysis, design, approval, dependencies, or
+multiple planned phases into a normal workplan.
+
+Ecosystem todos from other agents arrive as `[repo:whynot-design]` hub tasks —
+visible at session start. Pick one up by creating the workplan file, then registering
+the workstream.
+
+Task blocks use this shape:
+
+```task
+id: WHYNOT-WP-NNNN-T01
+status: wait | todo | progress | done | cancel
+priority: high | medium | low
+state_hub_task_id: "<uuid>"         # written by fix-consistency — do not edit
+```
+
+Status progression is `todo` → `progress` → `done`; use `wait` for waiting or
+blocked work and `cancel` for stopped work.

+
+## Session Protocol
+
+**Start:**
+1. `cat .custodian-brief.md` — domain goal and open workstreams (offline-safe)
+2. Check inbox: `GET /messages/?to_agent=whynot-design&unread_only=true`; mark read
+3. Scan workplans: `ls workplans/` — note `status: ready`, `active`, or `blocked` files and open tasks
+4. Check human-needed tasks: `GET /tasks/?needs_human=true`
+
+**During work:**
+- Update task statuses in workplan files as tasks progress
+- Record significant decisions via `POST /decisions/`
+
+**Close:**
+1. Update workplan file task statuses to reflect progress
+2. Log: `POST /progress/` with a summary of what changed
+3. Note for the custodian operator: after workplan file changes, run from
+   `~/state-hub`:
+   ```bash
+   make fix-consistency REPO=whynot-design
+   ```
+   This syncs task status from files into the hub DB.
+
+---
+
+## Credential and access routing
+
+**Audience:** Codex, Claude Code, Grok, and custodian agents that call **llm-connect**
+for inference. Run this check **before** requesting secrets, API keys, SSH access,
+login tokens, or database passwords — in any repo, not only `ops-warden`.
+
+ops-warden **issues SSH certificates only** (`warden sign`, `cert_command`). Every
+other credential need belongs to another subsystem. **Do not** message
+`ops-warden` on State Hub expecting a secret value; the reply is a pointer, not a key.
+
+### Lookup (do this first)
+
+```bash
+warden route find "<describe your need>" --json
+warden route show <catalog-id> --json
+```
+
+Requires the `warden` CLI from `~/ops-warden` (`uv tool install .` or `uv run warden`).
+
+| Agent runtime | How to orient |
+| --- | --- |
+| **Codex / Grok** (shell, HTTP State Hub) | `warden route` commands above; inbox `to_agent=whynot-design` is for coordination, not secret vending |
+| **Claude Code** (MCP when available) | `get_domain_summary("custodian")` for workstreams; **still** use `warden route` for credential ownership |
+| **llm-connect** (inference service) | Never put secret retrieval in prompts; route custody to OpenBao/operator paths surfaced by `warden route` |
+
+### Quick routing table
+
+| I need… | Owner | ops-warden executes? |
+| --- | --- | --- |
+| SSH cert (`adm`/`agt`/`atm`) | ops-warden | **Yes** — `warden sign` |
+| API key, DB password, provider token | OpenBao (`railiance-platform`) | No — route only |
+| Login / OIDC / MFA | key-cape / Keycloak | No — route only |
+| Authorization decision | flex-auth | No — route only |
+| activity-core → issue-core emission | activity-core + issue-core | No — `warden route show activity-core-issue-sink` |
+| SSH tunnel | ops-bridge (+ `cert_command` from warden) | No — route only |
+
+### Anti-patterns (do not do these)
+
+- `POST /messages/` to `ops-warden` asking for `ISSUE_CORE_API_KEY`, `OPENROUTER_API_KEY`, etc.
+- Inventing `warden secret`, `warden login`, `warden bao`, `warden tunnel` — they do not exist
+- Pasting secrets into Git, State Hub, workplans, logs, or chat
+
+### Other capabilities (reuse-surface)
+
+Non-credential capabilities are usually discovered through **reuse-surface** federation
+(`reuse-surface` registry / `capability.*` indexes). Credential routing is inlined in
+every repo's agent instructions because it is high-frequency, high-risk, and easy to
+get wrong.
+
+**Canon:** `~/ops-warden/wiki/CredentialRouting.md` · catalog `~/ops-warden/registry/routing/catalog.yaml`
+
+<!-- REPO-AGENTS-EXTENSIONS -->
+<!-- Append repo-specific agent instructions below this marker.
+     The state-hub template sync preserves content after this line. -->
+
+---
+
+## Workplan Convention (ADR-001)
+
+Work items originate as files in this repo — not in the hub. The hub is a
+read/cache/index layer that rebuilds from files.
+
+**File location:** `workplans/WHYNOT-WP-NNNN-<slug>.md`
+
+**Archived location:** finished workplans may move to
+`workplans/archived/YYMMDD-WHYNOT-WP-NNNN-<slug>.md`. The `YYMMDD` prefix is
+the completion/archive date; the frontmatter `id` does not change.
+
+**Ad Hoc Tasks:** small opportunistic fixes discovered during a session use
+`workplans/ADHOC-YYYY-MM-DD.md` with task ids `ADHOC-YYYY-MM-DD-T01`, etc. Use
+this only for low-risk work completed directly; create a normal workplan for
+anything needing analysis, design, approval, dependencies, or multiple phases.
+
+**Frontmatter:**
+
+```yaml
+---
+id: WHYNOT-WP-NNNN
+type: workplan
+title: "..."
+domain: infotech
+repo: whynot-design
+status: proposed | ready | active | blocked | backlog | finished | archived
+owner: codex
+topic_slug: ...
+created: "YYYY-MM-DD"
+updated: "YYYY-MM-DD"
+state_hub_workstream_id: "<uuid>"   # written by fix-consistency — do not edit
+---
+```
+
+Use `proposed` for a new draft, `ready` after review against current repo
+state, and `finished` after implementation. `stalled` and `needs_review` are
+derived health labels, not frontmatter statuses.
+
+**Task block format** (one per `##` section):
+
+```
+## Task Title
+
+` ` `task
+id: WHYNOT-WP-NNNN-T01
+status: wait | todo | progress | done | cancel
+priority: high | medium | low
+state_hub_task_id: "<uuid>"         # written by fix-consistency — do not edit
+` ` `
+
+Task description text.
+```
+
+Status progression: `todo` → `progress` → `done`; use `wait` for waiting/blocked work and `cancel` for stopped work.
+
+To create a new workplan:
+1. Write the file following the format above
+2. Notify the custodian operator to run `make fix-consistency REPO=whynot-design`
+   (or send a message to the hub agent via `POST /messages/`)

+### Added
+
+- **Lit adapter completed + refresh pipeline** (WHYNOT-WP-0002, Phases 3–6). The
+  one-way `React → designbook/ → ir/ → adapters/lit` pipeline is now end-to-end:
+  - `make adapt-lit` gains **component scaffold + drift** (T07): parses
+    `src/elements/*.js`, compares each `<wn-*>` to its IR contract, and writes
+    per-component drift reports + a machine roll-up (`adapters/lit/drift/`), with
+    write-once stubs (`adapters/lit/stubs/`) for new components — never overwriting
+    hand-authored sources. Severity split: actionable drift gates (exit 3);
+    `non-portable`/`prop-extra` are informational.
+  - `make parity-lit` (T08): renders every `<wn-*>` in a real browser and asserts
+    **contract + visual parity**, writing `adapters/lit/parity/_parity.json`
+    (exit 4 on failure).
+  - `make designbook-refresh` (T09): the refresh orchestrator
+    (check→pull→sync→ir→adapt-lit→drift-triage→parity) honouring the adapter
+    exit-code contract, plus a drift-resolution runbook in `designbook/README.md`.
+  - `make adapt-plain-css` (T10): a deliberately-unfinished second-adapter **smoke**
+    proving the IR/adapter seam — a non-Lit adapter consuming the same `ir/` with the
+    same contract shapes and zero `ir/` changes.
+- **Drift triage resolved — `make designbook-refresh` is green** (0 drift, parity pass).
+  The three surfaced divergences were resolved without any stack→React back-edit:
+  a documented `TAG_OVERRIDES` in the extractor maps `PipelineStrip → wn-pipeline`
+  (the tag is an IR-projection detail); the drift detector now recognises a prop
+  honoured by a same-named named slot (`<wn-page-header>` `actions`); and an auditable
+  `adapters/lit/drift.accepted.json` registry records the intentional Sidebar
+  composition divergence (`current` key ↔ per-item `active`) as a justified,
+  non-gating note.
+
+## [0.4.0] — 2026-06-28
+
+### Fixed
+
+- **Showcase page no longer wedges the renderer** (WHYNOT-WP-0002 T11). `<wn-breadcrumb>`
+  inserted separator elements into its own light DOM on `slotchange` while cleaning up
+  in the shadow DOM, so separators were never removed — each insertion re-fired
+  `slotchange` and the main thread looped forever, so `examples/showcase/index.html`
+  never finished rendering. `WnBreadcrumb._onSlot` is now idempotent (excludes its own
+  separators; mutates only when they are not already correct). The showcase visual test
+  is un-`fixme`'d and captures a stable `showcase.png`, unblocking WHYNOT-WP-0003 T08
+  (showcase as per-version visual catalog).
+
+### Removed
+
+- **Dead Google-Fonts `@import`** from `src/styles/colors_and_type.css`. Every token
+  font stack is system-ui based, so the imported IBM Plex webfont was unused; it was
+  also a documented source of CI flakiness. No visual change (system fonts unchanged).
+
+### Added
+
+- **Versioned IR manifest + consumer drift-check** (WHYNOT-WP-0003, Phase 1–4). The
+  `ir/` contract is now the unit of versioned downstream consumption:
+  - `ir/manifest.json` (T03) — per-version inventory + diff anchor:
+    `{ schemaVersion, designVersion, generatedAt, tokensHash, components:[{name,group,hash}] }`,
+    each hash a deterministic sha256 over canonicalised JSON (formatting-invariant,
+    `generatedAt` reused on no-op runs → no git churn). Schema:
+    `ir/schema/manifest.schema.json`. Emitted by `make ir`.
+  - `ir/INDEX.md` (T07) — human-readable catalog generated from the contracts;
+    browse a version without cloning or running anything. Emitted by `make ir`.
+  - **`npx @whynot/design drift`** (T05) — consumer-side drift-check (`bin/whynot-design.mjs`,
+    new `bin` entry). Compares a consumer's adopted `.whynot-design.lock` against the
+    installed package's manifest and reports added/changed/removed components + token
+    changes (`--json`, `--update`, `--manifest`, `--version`, `--lock`). Exit codes
+    mirror the adapter contract: `0` in sync · `2` usage error · `3` drift.
+  - `.whynot-design.lock` sync-point format (T04) — `ir/schema/lock.schema.json` +
+    documented lifecycle (consumer-side mirror of `designbook/.design-sync.json`).
+  - `CONSUMING.md` (T06) — pin → inspect → drift → update guide, with a runnable
+    `examples/consumer-fixture/`; cross-linked from `README.md` and `MultiFrameworkSupport.md`.
+  - `CONSUMER_CONTRACT_PARITY.md` (T09) — design-only note + recorded go/defer
+    decision for the heavier live-UI-vs-contract parity mode (deferred).
+- **Publishable to the coulomb Gitea npm registry** (WHYNOT-WP-0003 T02) — `private:false`,
+  `publishConfig.registry`, real `repository.url`, an `.npmrc` scope + `${NPM_AUTH_TOKEN}`
+  reference (no secret committed), and `PUBLISHING.md` (publish flow + consumer install +
+  token routing). The package now ships the `ir/` consumer contract (added to `files` and
+  the `./ir/*` export) so consumers can pin a version and track it.
+
+### Changed
+
+- **`lit` is now a `peerDependency`** (`^3`), not a direct dependency. Consumers must
+  install `lit` alongside `@whynot/design` (`npm i @whynot/design lit`) so their bundler
+  dedupes to a single `lit` instance.
+
+## [0.3.0] — 2026-06-27
+
+### Added
+
+- **Technology-neutral IR + stack-adapter pipeline** (WHYNOT-WP-0002, Phase 0–3). The
+  design language is now authored once in the canonical React designbook and projected
+  one-way onto each stack: `React → designbook/ → ir/ → adapters/<stack>/`.
+  - `ir/` — committed, diffable blueprint: `ir/SCHEMA.md`, JSON Schemas
+    (`ir/schema/{component,tokens}.schema.json`), and the extractor's output
+    (`ir/tokens.json` in W3C DTCG format, `ir/components/*.json`, `ir/exemplars/*`).
+  - `adapters/ADAPTER_CONTRACT.md` — the contract every stack adapter implements
+    (inputs, drift report + parity result shapes, idempotency, CI exit codes).
+  - `scripts/designbook_pull.py` + `make designbook-pull` — pulls the React designbook
+    from Claude Design into `designbook/` (the bundled `/design-sync` skill only
+    *pushes*, so it cannot populate `designbook/`).
+  - `scripts/ir-extract.mjs` + `make ir` — extracts the IR from the `.jsx` ui-kit,
+    manifest, and previews.
+  - `adapters/lit/` + `make adapt-lit` — Lit reference adapter; tokens fully generated
+    into `src/styles/colors_and_type.css` (marker-bounded, idempotent).
+  - `.claude/rules/designbook-propagation.md` + `DesignSystemIntroduction.md` §5.1 —
+    one-way governance and drift-resolution workflow.
+
+### Changed
+
+- `src/styles/colors_and_type.css` — token `:root` block is now **generated** by
+  `make adapt-lit` from `ir/tokens.json` (between `@generated tokens` markers). This
+  synced the Lit token layer to the canonical React designbook: font stacks switched
+  from IBM Plex to system-font stacks, and the functional-status tokens
+  (`--status-error/warn/success/info` + `-bg`) were added. **Visual change — Playwright
+  baselines need review + `pnpm test:visual:update`.**
+
+### Fixed
+
+- **Visual-regression harness now renders deterministically.** The four
+  `examples/whynot-control` pages render and screenshot cleanly against the new tokens.
+  Snapshot baselines are now **gitignored** (generated locally via
+  `pnpm test:visual:update`, not committed — they are large binary test artifacts).
+  Along the way:
+  - `serve.json` (`cleanUrls:false`) — the static server was 301-redirecting
+    `/…/index.html` to a trailing-slash-stripped URL, shifting the document base and
+    404'ing every relative asset (also broke `pnpm showcase` in the browser).
+  - `examples/whynot-control/index.html` — token stylesheet linked a non-existent
+    root path; repointed to `../../src/styles/colors_and_type.css` so the page picks
+    up the design tokens.
+  - `examples/vendor/lit.js` — vendored a self-contained esbuild bundle of `lit` and
+    pointed the showcase importmap at it, replacing the multi-hop live esm.sh module
+    graph (regen command noted in the showcase importmap comment).
+  - `tests/visual/ui-kit.spec.mjs` — abort the (unused, post-IBM-Plex) Google-Fonts
+    CDN in tests; a hung font request was blocking module execution and `load`.
+- The `showcase` "every component" visual test is `test.fixme` pending
+  **WHYNOT-WP-0002-T11** — that page wedges the renderer main thread (a demo
+  composition loops); the four control baselines are unaffected.

+# Design note — consumer-side contract parity (WHYNOT-WP-0003 · T09)
+
+> **Status: design-only. Deferred — do not implement.** This note captures the
+> shape of the richer drift mode so the decision to build it is informed, not so
+> it gets built now. The must-have is the **snapshot diff** (`drift`, T05); this is
+> the heavier, per-stack second mode.
+
+## What it is
+
+The shipped `drift` check (T05) compares two **manifests** — the consumer's
+adopted `.whynot-design.lock` against a target `ir/manifest.json`. It answers
+*"what changed in the contract between the version I adopted and this one?"* It
+never looks at the consumer's actual UI.
+
+**Contract parity** is the inverse question: *"does my live rendered UI still
+match the contract I adopted?"* It compares a consumer's **live rendered
+elements' observed attributes / properties** against the IR component contracts
+(`ir/components/*.json`) — the consumer-side mirror of the upstream adapter parity
+(WHYNOT-WP-0002 · T08), which checks the Lit stack against the designbook
+exemplars.
+
+```
+T05 (shipped):     .whynot-design.lock   ── snapshot diff ──▶   ir/manifest.json
+                   (contract vs contract, version-to-version)
+
+T09 (this note):   live rendered elements ── parity ──▶   ir/components/*.json
+                   (running UI vs contract, per-stack introspection)
+```
+
+## Why it is heavier (the reason to defer)
+
+Snapshot diff is pure data: hash vs hash, no runtime, no DOM, network-free,
+stack-agnostic. Contract parity needs to **observe a running UI**, which makes it
+fundamentally per-stack:
+
+- **Introspection substrate.** You must render each component and read back its
+  realised attributes/properties/slots — a browser/JSDOM/per-framework harness
+  the consumer has to stand up. There is no framework-neutral way to enumerate
+  "what props did this element actually accept."
+- **Coverage problem.** A consumer renders components with *its own* prop
+  combinations; parity can only check what the consumer actually mounts, so
+  "no parity failures" ≠ "fully conformant." It needs a fixture/exemplar set,
+  which re-introduces per-stack authoring.
+- **Non-portable props.** React objects / render-props / callbacks
+  (`portable:false` in the IR) have no attribute form to observe — exactly the
+  class the adapter contract already surfaces as drift. Parity would have to
+  decide, per stack, what "matching" even means for them.
+- **Maintenance surface.** It is a second, stack-specific tool to keep in step
+  with every IR shape change, for a check the snapshot diff already covers at the
+  contract level.
+
+## Proposed shape (if/when built)
+
+- A `parity` subcommand alongside `drift`, opt-in, requiring the consumer to
+  declare a render harness + a fixture set (which elements, which prop combos).
+- Reuse of the adapter parity result shape (`adapters/ADAPTER_CONTRACT.md`
+  "Parity result — minimal machine shape") so upstream and downstream parity read
+  identically, and the existing exit codes (`0` ok · `4` parity failure).
+- Per-element issues drawn from the same vocabulary as adapter drift:
+  `prop-missing`, `attribute-mismatch`, `variant-missing`, `removed-prop`,
+  `non-portable`.
+
+## Decision
+
+**Defer.** Ship the snapshot diff (`drift`, T05) as the must-have downstream
+check; record contract parity as a known, designed-but-unbuilt second mode. It
+becomes worth building only when a consuming repo has a real conformance need
+(e.g. an automated gate that its live UI has not silently diverged from an adopted
+contract) — at which point this note is the starting blueprint. Tracked as the
+go/defer decision recorded against this workplan via `record_decision`.
+
+This also keeps the **one-way constraint** intact: like `drift`, a future
+`parity` is read-only against the package and writes nothing back to
+whynot-design — it only observes the consumer's own UI.

+# Consuming whynot-design from another repo
+
+whynot-design is the **upstream visual reference** for other repos. It is a
+development reference and demo platform — it does not run as a production
+workload and handles no critical data. Consuming repos build their production
+UIs *from* it, and follow up on changes **at their own pace** — they are never
+force-synced.
+
+A consumer tracks the **IR** (`ir/`), not the Lit internals. The IR is the
+technology-neutral contract: per-component contracts (`ir/components/*.json`),
+W3C-DTCG tokens (`ir/tokens.json`), exemplars, and the version anchor
+`ir/manifest.json`. Three moves make this work:
+
+1. **Pin** a version — the package + your lockfile.
+2. **Inspect** it — `ir/INDEX.md` (browsable) + `ir/manifest.json` (machine).
+3. **Get a grip on changes** — `npx @whynot/design drift`.
+
+This is the inverse of whynot-design's own upstream machinery
+(`Claude Design → designbook/ → ir/`), now pointed downstream
+(`ir/ → your repo`). It is **one-way**: you read the IR; you never write back.
+
+---
+
+## 1. Pin a version
+
+`@whynot/design` is published to the coulomb Gitea npm registry. Pin an exact
+tagged version; your lockfile becomes the real pin.
+
+```bash
+# .npmrc in your repo (see PUBLISHING.md for the read-token routing)
+# @whynot:registry=https://gitea.coulomb.social/api/packages/coulomb/npm/
+
+npm i @whynot/design@0.3.0 lit
+```
+
+`lit` is a **peer dependency** — install it alongside so your bundler dedupes to
+a single `lit` instance.
+
+## 2. Inspect what you pinned
+
+No clone, no build needed:
+
+- **`node_modules/@whynot/design/ir/INDEX.md`** — human-readable catalog: every
+  component, its tag, props/variants/slots/events, and a link to its exemplar.
+- **`node_modules/@whynot/design/ir/manifest.json`** — the machine inventory:
+  `designVersion`, a `tokensHash`, and a content `hash` per component.
+
+## 3. Adopt a sync-point
+
+Record which IR state your repo has reconciled against. Run once, in your repo root:
+
+```bash
+npx @whynot/design drift --update
+```
+
+This writes **`.whynot-design.lock`** — commit it. It is the consumer-side mirror
+of whynot-design's own `designbook/.design-sync.json`.
+
+### `.whynot-design.lock` format
+
+```json
+{
+  "designVersion": "0.3.0",
+  "adoptedAt": "2026-06-27T17:31:08.640Z",
+  "manifestSchemaVersion": "1.0.0",
+  "manifestHashes": {
+    "tokens": "sha256:426f565a9ce6c36f",
+    "components": {
+      "Button": "sha256:4a32713049e433dd",
+      "TopNav": "sha256:32ebc6e46db38f93"
+    }
+  }
+}
+```
+
+| field | meaning |
+| --- | --- |
+| `designVersion` | the `@whynot/design` version you adopted |
+| `adoptedAt` | when you adopted it (first adopt, or last `drift --update`) |
+| `manifestSchemaVersion` | the manifest's shape version; a mismatch warns that hashes may not be directly comparable |
+| `manifestHashes.tokens` | adopted value of the manifest `tokensHash` |
+| `manifestHashes.components` | adopted content hash per component |
+
+**Lifecycle:** created on first `drift --update`, advanced only by a later
+`drift --update`. Nothing else writes it. Schema: `ir/schema/lock.schema.json`.
+
+## 4. Follow up at your own pace
+
+When you bump `@whynot/design` (or just want to know what moved), run:
+
+```bash
+npx @whynot/design drift
+```
+
+It compares your adopted `.whynot-design.lock` against the installed package's
+`ir/manifest.json` and reports **added / changed / removed** components plus
+whether **tokens** changed:
+
+```
+whynot-design drift
+  adopted: 0.3.0  (2026-06-27T17:31:08.640Z)
+  target:  0.4.0  (2026-07-10T09:02:11.400Z)
+
+Tokens:     changed
+Components:  +1 added · ~1 changed · -0 removed · 11 total
+  + Banner
+  ~ Button
+
+Drift detected vs your adopted sync-point.
+Adopt this version:  npx @whynot/design drift --update
+```

 The whole loop, warm, takes minutes. **Automation works only because every step has a deterministic check** — visual regression on both sides, semver, changelogs. Skip those and the pipeline is a slow manual process with extra tools.
 
+### 5.1 The IR pivot — technology-neutral propagation (WHYNOT-WP-0002)
+
+Claude Design's `/design-sync` produces a **React-bound** designbook. To keep the
+language portable across UI stacks (Lit today, others later) without forking it
+per stack, an **intermediate representation (IR)** sits between the atelier and
+each stack's source:
+
+```
+Claude Design (React)  ──/design-sync──▶  designbook/  ──make ir──▶  ir/  ──make adapt-lit──▶  src/ (Lit)
+   canonical authoring        React mirror      neutral blueprint        per-stack adapter
+```
+
+**Directionality is one-way: React → IR → stacks.**
+
+- The **React designbook in Claude Design is canonical.** The shared language is
+  authored there; nothing downstream is the source of truth.
+- `ir/` is the **committed, diffable blueprint** (tokens in W3C DTCG format,
+  per-component contracts, reference exemplars). Only the extractor writes it —
+  never hand-edit `ir/tokens.json`, `ir/components/`, or `ir/exemplars/`. See
+  `ir/SCHEMA.md`.
+- Each stack has an **adapter** (`adapters/<stack>/`, contract in
+  `adapters/ADAPTER_CONTRACT.md`). Adapters are **scaffold + drift-detect**:
+  tokens fully generated, new components stubbed, changed components reported as
+  **drift** — the hand-authored source is never overwritten. Lit is the reference
+  adapter.
+- **Lit-side changes do not flow back automatically.** A change to the shared
+  language must be made in Claude Design (React) and re-propagated through the IR.
+  A Lit→React back-edit that bypasses Claude Design is a governance violation: it
+  silently desyncs the canonical source from the implementation.
+
+**Drift resolution workflow.** When `make adapt-lit` reports drift
+(`adapters/lit/drift/<Name>.md`, exit code `3`):
+
+1. **Triage** — read the drift report. Each issue is one of: prop missing,
+   attribute mismatch, variant added/removed, prop removed, or a **non-portable
+   prop** (a React object/render-prop/callback that has no clean attribute).
+2. **Decide the direction.** If the IR is right and Lit is stale, a human adjusts
+   the Lit element's contract/behaviour to match. If the *language itself* should
+   change, that edit goes to Claude Design (React) and re-propagates — not into Lit.
+3. **Behaviour is filled by a human**, guided by the stub's `TODO` and the drift
+   report. The adapter never authors behaviour.
+4. **Close** — re-run `make adapt-lit` until drift clears, then `make parity-lit`
+   (exit `0`) confirms contract + visual parity. A drift report is "closed" when
+   the next extract+adapt produces no issues for that component.

+flow is restated as an enforceable rule in

+
+A release is a **git tag** (`vX.Y.Z`) — the immutable anchor a consuming repo pins

+   `[Unreleased]` entry (the `pnpm check` gate enforces this).
+2. Pick the bump per the table above (`patch`/`minor`/`major`).
+3. Run **`make release VERSION=x.y.z`** (`scripts/release.mjs`). It:
+   - guards — refuses if the tree is dirty, if `vx.y.z` is already tagged, if a
+     `[x.y.z]` section already exists, or if `[Unreleased]` is empty;
+   - bumps `package.json`, relabels `[Unreleased]` → `[x.y.z] — <date>` and opens a
+     fresh empty `[Unreleased]`;
+   - commits `release: vx.y.z` and creates the annotated tag.
+4. `git push --follow-tags origin main`.
+5. Publish the package (see WHYNOT-WP-0003 T02) so consumers can `npm i` the version.

+# Publishing `@whynot/design`
+
+`@whynot/design` is published to the **coulomb Gitea npm registry** so consuming
+repos can pin a version (`npm i @whynot/design@x.y.z`) and track it at their own pace
+(WHYNOT-WP-0003). The git tag cut by `make release` (see `DesignSystemIntroduction.md`
+§6) is the version; publishing makes that version installable.
+
+- Registry: `https://gitea.coulomb.social/api/packages/coulomb/npm/`
+- `package.json` `publishConfig.registry` already points `npm publish` here.
+- `lit` is a **peerDependency** — consumers install it themselves so their bundler
+  dedupes to a single `lit` instance.
+
+## The token (never commit it)
+
+Publishing and installing `@whynot/*` need a Gitea package token. It is **not stored in
+this repo** — per `.claude/rules/credential-routing.md`, tokens are routed, not vended:
+a Gitea package token is operator/OpenBao-owned (`railiance-platform`). Obtain one from
+the operator and export it:
+
+```sh
+export NPM_AUTH_TOKEN=…        # Gitea package token; never paste into git/chat/logs
+```
+
+`.npmrc` (committed) references it via `${NPM_AUTH_TOKEN}` — no secret lives in the file.
+
+## Publish (maintainer)
+
+```sh
+git checkout main && git pull --ff-only
+make release VERSION=x.y.z      # bumps, cuts CHANGELOG, commits, tags  (§6)
+git push --follow-tags origin main
+npm publish                     # uses publishConfig.registry + NPM_AUTH_TOKEN
+```
+
+`npm publish` is **outward and immutable** — a published version cannot be silently
+replaced. Confirm the tag and `npm pack --dry-run` contents first.
+
+## Install (consumer)
+
+Add an `.npmrc` to the consuming repo so the `@whynot` scope resolves to the registry,
+then install the package plus the `lit` peer:
+
+```ini
+# .npmrc
+@whynot:registry=https://gitea.coulomb.social/api/packages/coulomb/npm/
+//gitea.coulomb.social/api/packages/coulomb/npm/:_authToken=${NPM_AUTH_TOKEN}
+```
+
+```sh
+npm i @whynot/design@x.y.z lit
+```
+
+The installed package carries the consumer-facing contract under `ir/` (component
+contracts, `tokens.json`, exemplars) reachable via the `./ir/*` export — that is what
+the `drift` check (WHYNOT-WP-0003 T05) reads to report changes between versions.

+> Lit (`adapters/lit/`) is the reference implementation. Django

+> set, not an IR adapter — it is exempt until/unless migrated.
+
+An adapter is **scaffold + drift-detect**, not full behavioural codegen:
+
+- **tokens** → fully generated (deterministic, re-run is a no-op when unchanged),
+- **new component** → a stub is generated (skeleton + typed inputs + a behaviour TODO),
+- **changed component** → a **drift report** is emitted; the hand-authored source is
+  **never overwritten**,
+- **appearance** → verified against the designbook's own exemplars (parity).
+
+Behaviour stays hand-authored per stack. The adapter keeps each component's
+*contract and appearance* aligned; it does not own its behaviour.
+
+---
+
+## Inputs
+
+The sole input is the committed IR (`ir/`, produced one-way from the React
+designbook — see `ir/SCHEMA.md`):
+
+| Input | What the adapter reads it for |
+|---|---|
+| `ir/tokens.json` | Token generation (W3C DTCG → stack-native token form). |
+| `ir/components/<Name>.json` | Per-component contract: props, prop→attribute map, slots, events, variants. |
+| `ir/exemplars/<Name>.{html,png}` | Reference render for visual parity. |
+| `ir/schema/` | The schemas the adapter may re-validate inputs against. |
+
+An adapter **MUST NOT** write to `ir/`. Flow is one-way: React → IR → stacks.
+
+## Outputs
+
+An adapter produces exactly three kinds of output:
+
+1. **Generated artifacts** into the stack's own source tree.
+   - Tokens: fully generated, deterministic (e.g. Lit → `src/styles/colors_and_type.css`).
+   - New-component stubs: written to the stack's component tree, marked generated,
+     with a behaviour `TODO`. A stub is created **only** when no hand-authored
+     counterpart exists.
+
+2. **A machine-readable drift report** — one file per drifted component plus a
+   roll-up. Lit writes these to `adapters/lit/drift/<Name>.md` (human view) backed
+   by a machine-readable summary. The report enumerates, per component:
+   - props present in IR but missing on the element (and vice-versa),
+   - prop→attribute mismatches,
+   - missing / extra / renamed variants,
+   - removed props,
+   - **non-portable props** (`portable:false`) surfaced explicitly — never dropped.
+
+3. **A parity result** — a single structured outcome per `make parity-<stack>`
+   covering (a) **contract parity** (observed attributes/properties vs IR) and
+   (b) **visual parity** (rendered component diffed against `ir/exemplars/<Name>`).

+   exists. Once a human has touched a component, the adapter never re-writes it —
+   it emits drift instead.
+3. **Behaviour is never overwritten.** No adapter output replaces hand-authored
+   behaviour. The strongest action against an existing component is a drift report.
+4. **Reports are overwritten, not appended.** Drift and parity outputs are
+   snapshots of the current IR-vs-source state; each run replaces the previous.
+5. **No network, no `ir/` writes.** Adapters are pure functions of `ir/` + the
+   stack source tree.
+
+## Exit codes (for CI)
+
+Every adapter command (`make adapt-<stack>`, `make parity-<stack>`) follows the
+same convention so pipelines can branch uniformly:
+
+| Code | Meaning |
+|---|---|
+| `0` | Success. Tokens/stubs generated; no drift; parity passed. |
+| `2` | Usage / configuration error (bad args, missing `ir/`, malformed input). |
+| `3` | **Drift detected.** Generation succeeded but one or more components drifted from the IR. Non-fatal by default; use to gate a review. |
+| `4` | **Parity failure.** A contract or visual parity check failed. |
+| `5` | Internal adapter error (unexpected exception). |
+
+Codes are additive in spirit but a command returns the **highest applicable**
+code (e.g. drift + parity failure → `4`). `make designbook-refresh` (T09) treats
+`3` as "stop for human drift triage" and `4` as "fail".
+
+## Implementing a new adapter — checklist
+
+1. Create `adapters/<stack>/` with a `README.md` pointing back to this contract.
+2. Implement token generation from `ir/tokens.json` → the stack's token form
+   (full gen, deterministic).
+3. Implement stub generation from `ir/components/<Name>.json` using the
+   **prop→attribute map** (respect `attribute:false` and `portable:false`).
+4. Implement drift detection against existing hand-authored sources → the drift
+   report shape above.
+5. Implement `make parity-<stack>` → the parity result shape above, reusing the
+   Playwright harness where the stack renders to HTML.
+6. Wire `make adapt-<stack>` and `make parity-<stack>`; honour the exit codes.
+
+See `adapters/lit/` for the reference implementation.

+# Lit reference adapter
+
+Projects the technology-neutral IR (`ir/`) onto the Lit stack. This is the
+**reference** adapter — the contract every stack adapter implements lives in
+[`adapters/ADAPTER_CONTRACT.md`](../ADAPTER_CONTRACT.md).
+
+Run it with **`make adapt-lit`** (`adapters/lit/adapt.mjs`).
+
+## What it does
+
+Per the contract, an adapter is **scaffold + drift-detect**, never a rewrite:
+
+| Concern | Behaviour | Status |
+|---|---|---|
+| **Tokens** | **Fully generated** from `ir/tokens.json` into the `:root` block of `src/styles/colors_and_type.css`, between `@generated tokens` markers. Deterministic — re-running with an unchanged IR is a byte-identical no-op. The hand-authored type/utility CSS after the block is preserved. | **done (T06)** |
+| **New component** | Generate a `<wn-*>` Lit stub (`adapters/lit/stubs/<Name>.js`) from the IR contract's prop→attribute map + a behaviour `TODO`. **Write-once** — into a staging dir, never the hand-authored tree; the human integrates it. | **done (T07)** |
+| **Changed component** | Emit a **drift report** (`adapters/lit/drift/<Name>.md` + machine `_report.json`) — never overwrite the hand-authored element. | **done (T07)** |
+
+### Drift severity
+
+`make adapt-lit` exits `3` only on **actionable** drift — `prop-missing`,
+`attribute-mismatch`, `variant-axis-missing`, `tag-mismatch`. **Informational**
+issues do not gate: `non-portable` (React `style`/callbacks that inherently have
+no attribute form — the Lit element is right to omit them) and `prop-extra` (the
+Lit element is richer than the minimal React designbook). Resolve actionable drift
+per `.claude/rules/designbook-propagation.md` (fix the stack, or change the language
+in Claude Design and re-propagate — never a stack→React back-edit).
+
+## Parity — `make parity-lit`
+
+`adapters/lit/parity.mjs` renders every `<wn-*>` in a real browser (Playwright) and
+writes `adapters/lit/parity/_parity.json` (the contract's parity-result shape):
+
+- **Contract parity** — each element must upgrade and carry no `attribute-mismatch`
+  vs its IR contract (computed statically, so no runtime type-coercion false
+  positives). A prop the element *lacks* is a coverage note (already surfaced as
+  drift), not a parity failure.
+- **Visual parity** — a render smoke: the element renders non-empty with a positive
+  box; a screenshot is saved to `adapters/lit/parity/<Name>.png` (gitignored) as the
+  artifact. The `ir/exemplars/<Name>.html` are designbook **gallery cards** (a grid
+  of all variants), not single-component baselines, so an automated pixel diff
+  against them is not meaningful — per-component Lit appearance regression is owned
+  by the Playwright baseline suite (`tests/visual/`); the exemplar is the human
+  visual reference. Exit `4` on a contract or render failure.
+
+## Directionality
+
+One-way: **React → `ir/` → Lit**. This adapter is downstream of the IR; it never
+writes back to `ir/` or to the React designbook. A change to the shared language is
+made in Claude Design and re-propagated (`make designbook-pull && make ir &&
+make adapt-lit`). See `.claude/rules/designbook-propagation.md`.
+
+## Token regeneration is a visual change
+
+Because tokens are fully generated, regenerating them can change rendered
+appearance when the canonical React designbook has moved (e.g. a font-stack or
+colour change). That makes the Playwright baselines diverge **by design** — it is a
+human review point, not an error:
+
+```
+make adapt-lit          # regenerates tokens
+pnpm test:visual        # will fail where appearance changed
+# review the change, then if correct:
+pnpm test:visual:update # accept new baselines
+```
+
+Never run `test:visual:update` to silence a token change without reviewing it — that
+defeats the parity gate (T08).
+
+## Exit codes
+
+`0` ok · `2` usage/config · `3` drift detected · `4` parity failure · `5` internal.

+//
+// The gate that confirms the Lit elements actually honour the IR contract.
+// Renders each <wn-*> in a real browser (Playwright) and checks:
+//
+//   (a) CONTRACT parity — for every IR-declared portable prop the element HAS,
+//       setting the IR-declared attribute must drive the property (no attribute
+//       contradiction). A prop the element lacks is a *coverage* note, not a
+//       contradiction — it is already surfaced by `make adapt-lit` drift (T07).
+//   (b) VISUAL parity — the element renders non-empty with a positive box; a
+//       screenshot is saved to adapters/lit/parity/<Name>.png as the artifact.
+//
+//   On pixel-exact appearance: `ir/exemplars/<Name>.html` are designbook *gallery
+//   cards* (a grid of all variants), not single-component baselines, so a direct
+//   pixel diff against them is not meaningful. Per-component Lit appearance
+//   regression is owned by the Playwright baseline suite (tests/visual/). Visual
+//   parity here is a render smoke + artifact; the exemplar is the human reference.

+# plain-css adapter — second-adapter smoke (WHYNOT-WP-0002 · T10)
+
+> **This is not a finished stack.** It exists to prove the **IR/adapter boundary**:
+> that a second, non-Lit adapter can consume the *same* `ir/` and honour the *same*
+> [`adapters/ADAPTER_CONTRACT.md`](../ADAPTER_CONTRACT.md). The deliverable is
+> confidence in the seam, so the architecture can later be lifted into a
+> coulomb-level tool — **not** a usable plain-CSS component kit.
+
+Run with **`make adapt-plain-css`** (`adapters/plain-css/adapt.mjs`).
+
+## What it proves
+
+| Contract concern | This adapter | Same as Lit? |
+|---|---|---|
+| Input is `ir/` only | reads `ir/tokens.json` + `ir/components/*.json` | ✓ identical inputs |
+| Tokens fully generated | → `adapters/plain-css/tokens.css` (CSS custom properties, deterministic no-op re-run) | ✓ same discipline, different target |
+| New component → stub | write-once class stub `adapters/plain-css/stubs/<tag>.css` (base + variant modifier classes from the contract) | ✓ write-once, into a staging dir |
+| Drift roll-up | `adapters/plain-css/_report.json` in the contract's report shape (`stack`, `generatedAt`, `components[]`) | ✓ portable shape |
+| Exit codes | `0` ok · `2` usage · `3` new/drift · `5` internal | ✓ shared convention |
+
+Because plain-CSS has no hand-authored source, **every** IR component reports
+`status: "new"` and gets a stub — exactly the contract's new-component path. That a
+totally different stack reuses the same IR, the same report shape, and the same exit
+codes — with **zero changes to `ir/`** — is the proof the boundary holds.
+
+## What it deliberately does NOT do
+
+No real CSS appearance, no parity, no full component set, no integration into the
+repo's build. Finishing a plain-CSS (or Vue/Svelte/…) stack is future work; the seam
+is what T10 validates. See `DesignSystemIntroduction.md` §5.1 and the Lit reference
+adapter (`adapters/lit/`) for the full implementation.

+# 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.

+# designbook/
+
+Local mirror of the **whynot** Claude Design project (the atelier — source of truth
+for the visual *language*). This directory is written and read by the `/design-sync`
+skill (the `DesignSync` tool over the claude.ai login). It is **not** edited by the
+build scripts; `tokens/` and `src/styles/` in the repo root are *derived* from it.
+
+See `DesignSystemIntroduction.md` §1 (three places) and §5 (the atelier → repo hop),
+and `RecentChanges.md` (regenerated by `make designbook-sync`) for the last diff.
+
+## Refresh runbook — propagating a designbook change to Lit (WHYNOT-WP-0002)
+
+When the cloud designbook moves, run **`make designbook-refresh`** — it chains
+check → pull → record → `make ir` → `make adapt-lit` → (drift triage) → `make
+parity-lit` and stops when a human decision is needed. See
+`.claude/rules/stack-and-commands.md` for the step list and
+`.claude/rules/designbook-propagation.md` for the one-way governance.
+
+**Step 6 — resolving drift (the human step).** When `make adapt-lit` exits `3`,
+the refresh halts and points you at `adapters/lit/drift/<Name>.md`. For each
+**actionable** issue (informational `non-portable`/`prop-extra` are not gated):
+
+| drift kind | what it means | how to resolve |
+|---|---|---|
+| `attribute-mismatch` | the Lit property reflects a different attribute than the IR contract | rename the Lit `attribute:` to match the IR, or — if the *language* is what's wrong — change it in Claude Design and re-propagate |
+| `prop-missing` | the IR contract has a prop the `<wn-*>` element lacks | add the reactive property + behaviour to the element, **or** if the element models it differently (e.g. a slot, or state on a child), change the React designbook so the contract matches reality |
+| `variant-axis-missing` | an IR variant axis has no backing Lit property | add the variant property, or correct the axis in Claude Design |
+| `tag-mismatch` | the IR contract's tag has no element; a near-named one exists (e.g. `wn-pipeline-strip` vs the hand-authored `wn-pipeline`) | decide the canonical name **in Claude Design** and re-propagate, then realign the element — do not silently rename only the stack |
+
+**Never** resolve drift by editing `ir/` or back-editing React from the stack —
+that desyncs the canonical source (see `designbook-propagation.md`). After
+resolving, re-run `make designbook-refresh --no-pull` to confirm `adapt-lit` is
+clean and `parity-lit` passes (exit `0`). New components get a write-once stub in
+`adapters/lit/stubs/<Name>.js` — move it into `src/elements/`, implement the
+behaviour, register it, and re-run.
+
+## How it syncs
+
+The designbook is a cloud project of type `PROJECT_TYPE_DESIGN_SYSTEM`. Sync is
+**two-way and incremental — one component at a time, never a wholesale replace**:
+

+
+### Freshness marker — `.design-sync.json`
+
+`make designbook-sync` only reflects the latest design **if `/design-sync` has been run**.
+It cannot pull on its own (the pull is an agent step), so freshness is tracked in
+`.design-sync.json`:
+
+```json
+{ "lastSyncAt": "<ISO>", "remoteUpdatedAt": "<ISO>", "projectId": "…", "projectName": "…" }
+```
+
+- `--mark-synced` (run right after `/design-sync`) sets `lastSyncAt` to now. `RecentChanges.md`
+  and the `make` output then show **"Last /design-sync: &lt;datetime&gt;"**.
+- To detect that the cloud moved ahead, run **`make designbook-check`** — backed by
+  **llm-connect**. It uses the `claude-code` adapter to ask the local `claude` binary for the
+  project's current `updatedAt` via `DesignSync.list_projects`, then records it with
+  `node scripts/designbook-sync.mjs --remote-updated <iso>`. (Only the `claude-code` adapter can
+  see your Claude Design project; no secret goes in the prompt — DesignSync uses the claude.ai
+  login.) If `remoteUpdatedAt` is newer than `lastSyncAt`, every report **warns that the local
+  mirror is OUTDATED** until the next `/design-sync`. Run the check offline/manually with
+  `python scripts/check_designbook_staleness.py --remote-updated <iso>`.
+- If no sync has ever been recorded, the report warns that `/design-sync` has not run.
+
+Anthropic's guidance for keeping the system on-brand:
+
+- **Give explicit constraints** (fonts, colors, spacing, layout) — see `../README.md`,
+  which is the authoritative language spec. Vague input drifts to generic output.
+- **Show real rendered UI**, not just a token sheet — the `examples/` pages double as
+  brand exemplars here.
+- **Test one component before a full page.** If output is off, make the language more
+  explicit and retest — cheaper in tokens than fixing a whole screen.
+
