+# Homepage governance proof redesign
+
+Date: 2026-08-20. Status: approved direction, spec for implementation.
+
+## Problem
+
+The live homepage at primitree.com shows these defects, confirmed against
+screenshots and source:
+
+- `living-canopy.tsx` positions SVG `<text>` nodes at fixed coordinates inside
+  fixed-width `<rect>` nodes. `component.nav.active.bg` and the format list
+  overflow their boxes. SVG text neither wraps nor clips.
+- The proposal control truncates its token path mid-name.
+- Connector paths use sharp elbow segments at arbitrary angles.
+- The demo section spans 230vh with a sticky frame. An IntersectionObserver
+  flips a stage attribute as hidden sentinels pass, and the per-stage visual
+  change stays near invisible. Visitors read the frozen frame as a broken
+  page. This defect drives the most confusion reports.
+- Large empty regions: the hero right column, the void under the sticky
+  frame, and the lower left quadrant of the argument section.
+
+The page also omits the install command, the diff report, and any statement
+of DTCG conformance.
+
+## Positioning
+
+Primitree is a token governance standards library. The homepage leads with
+governance of local DTCG sources. Figma appears once, in a source adapter
+list, and nowhere else.
+
+## Goals
+
+- Demonstrate the check, trace, and build loop with output from the real
+  engine.
+- Remove all scroll-driven choreography. Motion follows clicks.
+- State DTCG 2025.10 conformance in concrete nouns.
+- Keep the committed brand system: root-black, lichen, bone, Inter,
+  Geist Mono, and the tokens in `apps/docs/DESIGN.md`.
+- All copy passes `check:prose` and `check:brand`.
+
+## Non-goals
+
+- No rebrand, no new typefaces, no new color tokens.
+- No changes to the docs section, the playground, or the header and footer
+  chrome.
+- No client-side execution of the token engine. The build step precomputes
+  every demo outcome.
+
+## Page structure
+
+Normal document flow, five sections, no sticky regions, no scroll observers.
+
+| #   | Section       | Content                                                                                                     |
+| --- | ------------- | ----------------------------------------------------------------------------------------------------------- |
+| 1   | Hero          | Existing headline and support copy, install command with copy button, two CTAs                              |
+| 2   | Proof panel   | Signature interaction: proposal chips, verdict, token tree, emitted code                                    |
+| 3   | Change review | Terminal block with real `primitree diff` report output                                                     |
+| 4   | Config        | Existing `primitree.config.ts` block with copy button, three-step trio, standards line, source adapter list |
+| 5   | Final CTA     | Existing closing section, unchanged                                                                         |
+
+## Section 1: hero
+
+Keep the headline and support paragraph. Fix the layout: support copy and
+CTAs align to the headline baseline grid instead of floating in the right
+column. Add an install row under the CTAs:
+
+```
+npx primitree@next check
+```
+
+The row renders as monospace text with a copy button. Copy buttons follow
+the docs convention of visible feedback on activation.
+
+## Section 2: proof panel, the signature interaction
+
+One panel, near one viewport tall, visible edge to edge while in view.
+Two regions: the token tree on the left, the evidence column on the right.
+On narrow viewports the evidence column stacks above the tree.
+
+### Proposal chips
+
+Three buttons across the top of the evidence column. Each applies a proposed
+change to `semantic.color.bg.brand`:
+
+1. Compliant alias change to `{primitives.color.green.500}`
+2. Layer violation: alias to `{component.color.brand}`
+3. Rename to `semantic.color.bg.primary`
+
+Chip activation updates, with no scroll dependence:
+
+- The verdict line: `PASS · 0 findings`, or `BLOCK · PT1004` with the rule
+  reason, or the rename report line with a breaking flag.
+- The affected tree edge, which draws along its path once per activation.
+- The emitted code pane: the exact `tokens.css` and `tokens.ts` lines for
+  the resolved value, or an empty state for a blocked change stating that
+  no files ship.
+
+A fourth resting state, active on load, shows the current passing graph.
+State transitions run on `aria-live="polite"` for the verdict line, matching
+the current implementation.
+
+### Data flow
+
+`lib/landing/governance-demo.ts` grows from one demo object to a set of
+precomputed outcomes. The module composes the graph, evaluates policy, and
+builds outputs through `@primitree/core` and `@primitree/dtcg` for each
+proposal at build time. The client component receives plain serializable
+data and switches between outcomes. Zero engine code reaches the client
+bundle.
+
+## Token tree
+
+HTML nodes in a CSS grid, with one inline SVG layer behind them for
+connectors. Node boxes size to their text content, which removes the
+overflow class of defects. Connector geometry derives from the grid rows,
+with orthogonal segments and rounded corners.
+
+Three labeled horizontal bands encode the layer architecture from the
+config:
+
+```
+canopy   component    component.button.bg · component.focus.ring · component.nav.active.bg
+trunk    semantic     semantic.color.bg.brand
+roots    primitives   primitives.color.blue.500
+```
+
+An output strip above the canopy lists the configured formats. The
+Primitree mark sits at the root band, at rest, without animation. Band
+labels use the Geist Mono label style from `DESIGN.md`.
+
+Edge treatments:
+
+- Alias edges: solid, lichen on the active path.
+- Dependency edges: solid, rule color.
+- Output edges: dashed, rule color.
+
+The one animation: on chip activation, the affected edge draws along its
+path over 300ms with an ease-out curve. `prefers-reduced-motion` disables
+the draw and swaps to an opacity change.
+
+## Section 3: change review terminal
+
+A terminal-styled block presenting real `primitree diff` output for the
+rename proposal:
+
+```
+$ primitree diff backup/tokens.json tokens.json --fail-on-breaking
+
+Variables: 1 renamed, 1 value change.
+The diff contains breaking changes.
+
+Renamed (breaking)
+- semantic.color.bg.brand -> semantic.color.bg.primary (Semantic)
+```
+
+The block content comes from the same precomputed demo module, with the
+report text checked against actual CLI output during implementation.
+Supporting copy states that the diff matches tokens by stable IDs and that
+a renamed token keeps its identity in the report.
+
+## Section 4: config, standards, sources
+
+The existing config block and three-step trio merge into one section, which
+removes the empty quadrant. Additions:
+
+- Copy button on the config block.
+- Standards line: DTCG 2025.10 output, Resolver contexts in
+  `tokens.resolver.json`, documented extensions under
+  `$extensions['com.primitree']`.
+- Source adapter list: local DTCG files, Figma variables export, Variables
+  REST API. The single Figma mention on the page.
+
+## Motion rules
+
+- No scroll-triggered animation, no sticky choreography, no parallax, no
+  observers.
+- Click-driven transitions with visible feedback at the click location.
+- `prefers-reduced-motion` swaps every transition to opacity or instant
+  state change.
+
+## Removals
+
+- The IntersectionObserver stage machinery, the stage track sentinels, the
+  230vh section, and the sticky frame in `living-canopy.tsx` and
+  `global.css`.
+- `living-canopy.tsx` itself, superseded by `token-tree.tsx` and
+  `proof-panel.tsx`. `scripts/brand-rules.mjs` lists this file in
+  `LICHEN_CONTRACT_PATHS`, so the list entry moves to the replacement file
+  that carries the lichen color.
+
+## New and changed files
+
+| File                                               | Change                                                               |
+| -------------------------------------------------- | -------------------------------------------------------------------- |
+| `apps/docs/lib/landing/governance-demo.ts`         | Precompute all proposal outcomes and emitted output excerpts         |
+| `apps/docs/components/landing/token-tree.tsx`      | New. Server-renderable tree: HTML nodes, SVG connectors, band labels |
+| `apps/docs/components/landing/proof-panel.tsx`     | New. Client component: chips, verdict, emitted code pane             |
+| `apps/docs/components/landing/governance-home.tsx` | Rewrite sections per this spec                                       |
+| `apps/docs/components/landing/living-canopy.tsx`   | Delete                                                               |
+| `apps/docs/app/global.css`                         | Remove canopy scroll styles, add proof panel and tree styles         |
+| `scripts/brand-rules.mjs`                          | Update `LICHEN_CONTRACT_PATHS`                                       |
+| `apps/docs/tests/*`                                | Update any homepage coverage                                         |
+
+## Accessibility
+
+- Chips form a `radiogroup` with arrow-key movement, matching the keyboard
+  pattern in the current tablist.
+- The verdict line keeps `role="status"` with `aria-live="polite"`.
+- The tree carries a `sr-only` description of nodes and edges, updated per
+  outcome.
+- Focus outlines follow the existing global focus style.
+
+## Responsive
+
+- Under 64rem: evidence column stacks above the tree, tree bands compress
+  to the stacked card list pattern from the current mobile fallback.
+- Node text never truncates. Long token paths wrap within their HTML boxes.
+
+## Copy constraints
+
+All new strings in TSX, including comments, pass `scripts/check-prose.mjs`.
+All color usage passes `scripts/check-brand.mjs`. New copy reuses the
+existing compliant register: concrete nouns, active voice, no quality
+adjectives.
+
+## Verification
+
+- `pnpm --filter primitree-docs run typecheck` and `run test`.
+- `node scripts/check-prose.mjs` and `node scripts/check-brand.mjs` from
+  the repo root.
+- Playwright screenshots at 1440x900 and 390x844, at rest and per chip
+  state, reviewed against this spec.
+- Keyboard pass: chips, copy buttons, CTAs reachable and operable.
+- Reduced-motion pass with emulated `prefers-reduced-motion`.

+# Homepage Governance Proof Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Replace the scroll-choreographed Living Canopy with a click-driven proof panel, a diff terminal, and a merged config section, per the spec at `docs/superpowers/specs/2026-08-20-homepage-governance-proof-design.md`.
+
+**Architecture:** `governance-demo.ts` gains a precomputed proposal deck built through `@primitree/core` and `@primitree/dtcg` at build time. A client `ProofPanel` switches between deck outcomes. A presentational `TokenTree` renders HTML nodes with CSS connectors. `governance-home.tsx` composes five sections in normal flow. Brand validators and tests retarget from the canopy to the new components.
+
+**Tech Stack:** Next.js 16 App Router, React 19, Tailwind 4 with handwritten classes in `apps/docs/app/global.css`, node:test, Playwright.
+
+## Global Constraints
+
+- Every string in TSX, including comments, passes `node scripts/check-prose.mjs`. Write zero comments in new components. Banned in copy, from `scripts/prose/rules.mjs`: em dashes, passive voice, `ensure`, `you can`, `lets you`, `only`, most `ly` adverbs, sentence-initial `If`, `Then`, or Wh-words, `simple`, `easy`, `consistent`, `flexible`, `seamless`, `powerful`.
+- Color values in UI sources pass `node scripts/check-brand.mjs`. Use `--color-primitree-*` variables from `global.css:5-26`. No former brand hex values.
+- No scroll observers, no sticky choreography, no `pointermove` listeners, no infinite animations. Brand rules enforce the last two on every `apps/docs/components/landing/` file.
+- Node >= 24, pnpm >= 11. Run docs commands as `pnpm --filter primitree-docs run <script>` from the repo root.
+- Commit after each task on branch `feat/homepage-governance-proof`.
+
+## Verified engine facts
+
+Values below come from running the packages in this workspace on 2026-08-20. Tests in the tasks pin them.
+
+- Green primitive `{ colorSpace: 'srgb', components: [0.372549, 0.498039, 0.184314], alpha: 1 }` resolves to hex `#5f7f2f` and passes policy with 0 findings when `semantic.color.bg.brand` aliases it.
+- `buildDTCGOutputs` emits `css/tokens.css` containing `  --semantic-color-bg-brand: var(--primitives-color-blue-500);` and `ts/tokens.ts` containing `  ["semantic.color.bg.brand"]: "color(srgb 0.2 0.4 1)",` for the baseline document.
+- `diffGraphViews(before, after)` for the rename returns five changes in this order: `changed component.button.bg`, `changed component.focus.ring`, `changed component.nav.active.bg`, `removed semantic.color.bg.brand`, `added semantic.color.bg.primary`. The removed and added changes each list the three component consumers as impacted. `GraphChange` reads `{ kind, tokenId, impactedTokenIds }`.
+- The blocked finding stays `PT1004` with message `Layer semantic cannot reference layer component.`
+
+---
+
+### Task 1: Proposal deck in governance-demo.ts
+
+**Files:**
+
+- Modify: `apps/docs/lib/landing/governance-demo.ts`
+- Test: `apps/docs/tests/governance-demo.test.ts`
+
+**Interfaces:**
+
+- Consumes: existing module internals: `compliantDocument`, `blockedDocument`, `policyInput`, `outputSet`, `buildSnapshot`, `requireBuildValue`, `resolveSrgbHex`.
+- Produces: `createProposalDeck(): ProposalDeck` and the exported types below. Task 3 reads `ProposalOutcome.tokenPath`, `.proposedValue`, `.resolvedValue`, `.description`, `.id`. Task 4 reads `.label`, `.verdict`, `.verdictTone`, `.detail`, `.emitted`. Task 5 reads `ProposalDeck.diffReport`.
+
+- [ ] **Step 1: Write the failing test**
+
+Append to `apps/docs/tests/governance-demo.test.ts`:
+
+```ts
+test('proposal deck derives every outcome from the engine', () => {
+  const deck = createProposalDeck()
+
+  assert.deepEqual(
+    deck.outcomes.map(outcome => outcome.id),
+    ['baseline', 'alias', 'violation', 'rename']
+  )
+
+  const [baseline, alias, violation, rename] = deck.outcomes
+  assert.equal(baseline.verdict, 'PASS · 0 findings')
+  assert.equal(baseline.resolvedValue, '#3366ff')
+  assert.match(
+    baseline.emitted?.css ?? '',
+    /--semantic-color-bg-brand: var\(--primitives-color-blue-500\);/u
+  )
+
+  assert.equal(alias.verdict, 'PASS · 0 findings')
+  assert.equal(alias.resolvedValue, '#5f7f2f')
+  assert.match(
+    alias.emitted?.css ?? '',
+    /--semantic-color-bg-brand: var\(--primitives-color-green-500\);/u
+  )
+  assert.match(alias.emitted?.ts ?? '', /color\(srgb 0\.372549/u)
+
+  assert.equal(violation.verdict, 'BLOCK · PT1004')
+  assert.equal(violation.detail, 'Layer semantic cannot reference layer component.')
+  assert.equal(violation.emitted, null)
+  assert.equal(violation.resolvedValue, null)
+
+  assert.equal(rename.tokenPath, 'semantic.color.bg.primary')
+  assert.equal(rename.verdict, '5 changes · 3 tokens affected')
+  assert.equal(deck.diffReport.includes('removed semantic.color.bg.brand'), true)
+  assert.equal(
+    deck.diffReport.includes(
+      '  Affected tokens: component.button.bg, component.focus.ring, component.nav.active.bg'
+    ),
+    true
+  )
+})
+```
+
+Add `createProposalDeck` to the import at the top of the file.
+
+- [ ] **Step 2: Run the test to verify it fails**
+
+Run: `pnpm --filter primitree-docs run test`
+Expected: FAIL, `createProposalDeck` has no export.
+
+- [ ] **Step 3: Implement the deck**
+
+In `apps/docs/lib/landing/governance-demo.ts`:
+
+3a. Add `diffGraphViews` to the `@primitree/core` import.
+
+3b. Add the green primitive inside `compliantDocument.primitives.color`, beside `blue`:
+
+```ts
+green: {
+  '500': {
+    $type: 'color',
+    $value: {
+      colorSpace: 'srgb',
+      components: [0.372549, 0.498039, 0.184314],
+      alpha: 1,
+    },
+  },
+},
+```
+
+3c. Add the two documents after `blockedDocument`:
+
+```ts
+const aliasDocument = {
+  ...compliantDocument,
+  semantic: {
+    color: {
+      bg: {
+        ...compliantDocument.semantic.color.bg,
+        brand: { $type: 'color', $value: '{primitives.color.green.500}' },
+      },
+    },
+  },
+} as const
+
+const renameDocument = {
+  primitives: compliantDocument.primitives,
+  semantic: {
+    color: {
+      bg: {
+        primary: { $type: 'color', $value: '{primitives.color.blue.500}' },
+        support: compliantDocument.semantic.color.bg.support,
+      },
+    },
+  },
+  component: {
+    button: {
+      bg: { $type: 'color', $value: '{semantic.color.bg.primary}' },
+    },
+    nav: {
+      active: {
+        bg: { $type: 'color', $value: '{semantic.color.bg.primary}' },
+      },
+    },
+    focus: {
+      ring: { $type: 'color', $value: '{semantic.color.bg.primary}' },
+    },
+    color: compliantDocument.component.color,
+  },
+} as const
+```
+
+3d. Add the types beside `GovernanceDemo`:
+
+```ts
+export interface ProposalOutcome {
+  readonly id: 'baseline' | 'alias' | 'violation' | 'rename'
+  readonly label: string
+  readonly tokenPath: string
+  readonly proposedValue: string
+  readonly verdict: string
+  readonly verdictTone: 'pass' | 'block' | 'review'
+  readonly detail: string
+  readonly resolvedValue: string | null
+  readonly emitted: { readonly css: string; readonly ts: string } | null
+  readonly description: string
+}
+
+export interface ProposalDeck {
+  readonly outcomes: readonly ProposalOutcome[]
+  readonly diffReport: readonly string[]
+}
+```
+
+3e. Add the helpers after `buildOutputLabels`:
+
+```ts
+function emittedExcerpt(document: unknown, cssNeedle: string, tsNeedle: string) {
+  const built = buildDTCGOutputs(
+    { ...outputSet, files: { 'living-canopy.tokens.json': document as DTCGDocument } },
+    {}
+  )
+  const findLine = (path: string, needle: string) => {
+    const file = built.files.find(item => item.path === path)
+    const line = file?.contents.split('\n').find(item => item.includes(needle))
+    if (line === undefined) {
+      throw new Error(`Governance demo expected ${needle} in ${path}.`)
+    }
+    return line.trim()
+  }
+  return Object.freeze({
+    css: findLine('css/tokens.css', cssNeedle),
+    ts: findLine('ts/tokens.ts', tsNeedle),
+  })
+}
+
+function inspectResolvedHex(
+  snapshot: ReturnType<typeof buildSnapshot>,
+  path: readonly string[]
+): string {
+  const inspection = requireBuildValue(
+    inspectToken(snapshot, { kind: 'path', path: [...path] }),
+    'proposal inspection'
+  )
+  return resolveSrgbHex(inspection.resolution.value)
+}
+
+function buildDiffReport(
+  before: ReturnType<typeof buildSnapshot>,
+  after: ReturnType<typeof buildSnapshot>
+): readonly string[] {
+  const paths = new Map<TokenId, string>()
+  for (const token of [...before.view.tokens, ...after.view.tokens]) {
+    paths.set(token.tokenId, token.path.join('.'))
+  }
+  const diff = requireBuildValue(diffGraphViews(before, after), 'rename diff')
+  const describe = (tokenId: TokenId) => {
+    const path = paths.get(tokenId)
+    if (path === undefined) {
+      throw new Error('Governance demo expected a path for every diff token.')
+    }
+    return path
+  }
+  const lines: string[] = [
+    '$ primitree diff tokens.before.json tokens.json --config primitree.config.ts',
+    '',
+    `Diff found ${diff.changes.length} token changes.`,
+  ]
+  for (const change of diff.changes) {
+    lines.push(`${change.kind} ${describe(change.tokenId)}`)
+    lines.push(
+      `  Affected tokens: ${
+        change.impactedTokenIds.length === 0
+          ? 'none'
+          : change.impactedTokenIds.map(describe).join(', ')
+      }`
+    )
+  }
+  lines.push('New findings: 0', 'Resolved findings: 0')
+  return Object.freeze(lines)
+}
+```
+
+3f. Add the deck builder at the end of the file:
+
+```ts
+/** Builds the click-driven proposal outcomes for the homepage proof panel. */
+export function createProposalDeck(): ProposalDeck {
+  const policy = requireBuildValue(createPolicy(policyInput), 'policy creation')
+  const baselineSnapshot = buildSnapshot(compliantDocument)
+  const aliasSnapshot = buildSnapshot(aliasDocument)
+  const renameSnapshot = buildSnapshot(renameDocument)
+
+  const aliasReport = requireBuildValue(
+    evaluatePolicy(aliasSnapshot, policy),
+    'alias policy evaluation'
+  )
+  if (aliasReport.summary.active !== 0) {
+    throw new Error('Governance demo expected the alias proposal to pass.')
+  }
+  const blockedReport = requireBuildValue(
+    evaluatePolicy(buildSnapshot(blockedDocument), policy),
+    'blocked policy evaluation'
+  )
+  const blockedFinding = blockedReport.findings.find(finding => finding.ruleId === 'PT1004')
+  if (blockedFinding === undefined) {
+    throw new Error('Governance demo expected the PT1004 finding.')

+
+**Files:**
+
+- Create: `apps/docs/components/landing/token-tree.tsx`
+- Modify: `apps/docs/app/global.css` (append styles)
+
+**Interfaces:**
+
+- Consumes: `GovernanceDemo` and `ProposalOutcome` from Task 1.
+- Produces: `TokenTree({ demo, outcome }: { demo: GovernanceDemo; outcome: ProposalOutcome })`. Task 4 renders it. The brand contract in Task 5 pins `tree-mark-body`, `tree-root-node`, `tree-trunk`, and `tree-token-node`.
+
+Layout, bottom-up like the config layers: mark, roots band with the alias node, trunk band with the governed token, canopy band with the three consumers, output strip on top. CSS connectors replace all SVG paths except the mark. HTML nodes size to their text, so long paths wrap instead of overflowing.
+
+- [ ] **Step 1: Create the component**

+### Task 5: Homepage swap, canopy removal, brand contract retarget
+
+One atomic task: the page rewires to the new components, `living-canopy.tsx` leaves, its styles leave, and every validator and unit test that references it retargets. The suite stays green at the commit boundary.
+
+**Files:**
+
+- Modify: `apps/docs/components/landing/governance-home.tsx`
+- Delete: `apps/docs/components/landing/living-canopy.tsx`
+- Modify: `apps/docs/app/global.css`
+- Modify: `scripts/brand-rules.mjs`
+- Modify: `scripts/check-brand.test.mjs`
+- Modify: `apps/docs/tests/color-system.test.ts`
+
+**Interfaces:**
+
+- Consumes: `ProofPanel` (Task 4), `CopyCommand` (Task 2), `createGovernanceDemo`, `createProposalDeck` (Task 1).
+- Produces: the final page. Task 6 writes e2e selectors against these class names: `.proof-chips`, `.proof-verdict`, `.tree`, `.terminal`, `.hero-install`.

+
+```bash

+- [ ] **Step 3: Update global.css**
+
+3a. Remove every rule whose selector mentions `canopy` (the `/* ---------- living canopy ---------- */` block, the media-query overrides near lines 941-1160, and `.canopy-tabs button:focus-visible` plus `.canopy-proposal:focus-visible` from the shared focus list at lines 99-100).

+  font-family: var(--font-mono);
+  font-size: 13px;
+  color: var(--color-primitree-text);

+
+3c. Add section scaffolding:

+
+Reconcile the existing `.governance-quickstart`, `.governance-proof`, `.governance-code-block`, and `.governance-command-row` rules with the merged section: keep them, and move the `.governance-argument-flow` rules from the removed consequences section into the quickstart context (stacked column, gap 24px). Remove `.governance-consequences`, `.governance-argument`, and `.governance-argument-intro` rules with the section.
+
+Add the focus-visible selectors for the new controls to the shared focus list at `global.css:89-100`: `.proof-chips button:focus-visible`, `.copy-command:focus-visible` already has its own rule, so list membership stays optional for it.
+
+- [ ] **Step 4: Retarget brand rules**
+
+In `scripts/brand-rules.mjs`:
+
+4a. In `LICHEN_CONTRACT_PATHS`, replace `'apps/docs/components/landing/living-canopy.tsx'` with `'apps/docs/components/landing/token-tree.tsx'`.
+
+4b. In `addLivingCanopyMarkupViolations` (line ~385): change the path guard to `'apps/docs/components/landing/token-tree.tsx'`. Replace the body-fill check with a class-based check, and keep the root-node check:
+
+```js
+function addLivingCanopyMarkupViolations(violations, path, content) {
+  if (path !== 'apps/docs/components/landing/token-tree.tsx') return
+
+  if (!/\bclassName=['"]tree-mark-body['"]/u.test(content)) {
+    violations.push({
+      path,
+      line: null,
+      match: 'token tree mark: missing Bone body class',
+    })
+  }
+
+  if (!/\bclassName=['"]tree-root-node['"]/u.test(content)) {
+    violations.push({
+      path,
+      line: null,
+      match: 'token tree mark: missing structural Lichen root node',
+    })
+  }
+}
+```
+
+4c. In `addLivingCanopyStyleViolations` (line ~451), replace `expectedTreatments` with:
+
+```js
+const expectedTreatments = [
+  {
+    label: 'Bone logo body',
+    property: 'fill',
+    selector: '.tree-mark-body',
+    value: 'var(--color-primitree-text)',
+  },
+  {
+    label: 'Lichen root node',
+    property: 'background',
+    selector: '.tree-root-node',
+    value: 'var(--color-primitree-accent)',
+  },
+  {
+    label: 'Lichen structural trunk',
+    property: 'background',
+    selector: '.tree-trunk',
+    value: 'var(--color-primitree-accent)',
+  },
+  {
+    label: 'Lichen governed-token border',
+    property: 'border-color',
+    selector: '.tree-token-node',
+    value: 'var(--color-primitree-accent)',
+  },
+]
+```
+
+4d. `addHomepageRegressionViolations` needs no change: its path guard covers every landing file.
+
+4e. Search `scripts/check-brand.test.mjs` for `living-canopy` and `living canopy` and update each fixture path and message expectation to the new file and the `token tree mark:` prefix. The regression fixture at line ~531 changes its `path` to `'apps/docs/components/landing/token-tree.tsx'`.
+
+- [ ] **Step 5: Update color-system.test.ts**
+
+Retarget the four tests that read `living-canopy.tsx`:
+
+- `living canopy never fades text-bearing stages or graph nodes`: rename to `token tree keeps node text at full opacity` and assert `global.css` contains no `opacity` declaration inside `.tree-node` or `.proof-` rules. Read the file and use a regex over the relevant blocks.
+- `living canopy provides a legible compact graph below tablet width`: rename to `token tree stacks below tablet width` and assert `global.css` matches `/@media \(max-width: 719px\)[\s\S]*?\.tree-band\s*\{[\s\S]*?grid-template-columns: minmax\(0, 1fr\);/u` and `token-tree.tsx` contains `className='tree'`.
+- `documentation brand files contain no former Primitree purple treatment`: swap the read of `living-canopy.tsx` for `token-tree.tsx` and add `proof-panel.tsx` to the source list.
+- `living canopy makes the Bone mark a structural Lichen root`: rename to `token tree makes the Bone mark a structural Lichen root` and assert `token-tree.tsx` matches `/className='tree-mark-body'/u` and `/className='tree-root-node'/u`, and `global.css` matches `/\.tree-mark-body\s*\{\s*fill: var\(--color-primitree-text\);/u` and `/\.tree-trunk\s*\{[\s\S]*?background: var\(--color-primitree-accent\);/u`.
+
+- [ ] **Step 6: Run every gate**
+
+```bash
+pnpm --filter primitree-docs run typecheck
+pnpm --filter primitree-docs run test
+node scripts/check-prose.mjs
+node scripts/check-brand.mjs
+node --test scripts/check-brand.test.mjs
+```
+
+Expected: all pass. Fix regressions before committing.
+
+- [ ] **Step 7: Visual smoke check**
+
+```bash
+pnpm --filter primitree-docs run dev
+```
+
+Screenshot `http://localhost:3000` at 1440x900 and 390x844 with the Playwright script pattern from the audit (`chromium.launch`, `page.screenshot`). Confirm: no text overflow in tree nodes, chips switch the verdict and emitted lines, no sticky behavior on scroll, hero reads as one column.
+
+- [ ] **Step 8: Commit**
+
+```bash
+pnpm exec prettier --write apps/docs/components/landing/governance-home.tsx apps/docs/app/global.css scripts/brand-rules.mjs scripts/check-brand.test.mjs apps/docs/tests/color-system.test.ts
+git add -A
+git commit -m "feat(docs): replace scroll canopy with click-driven governance proof"
+```
+
+---
+
+### Task 6: Rewrite the homepage e2e spec
+
+**Files:**
+
+- Modify: `tests/e2e/docs-home-governance.spec.ts`
+
+**Interfaces:**
+
+- Consumes: page selectors from Task 5: `.proof-chips button`, `.proof-verdict`, `.tree`, `.terminal`, `.hero-install`, plus existing `.governance-hero`.
+
+- [ ] **Step 1: Rewrite the spec**
+
+Keep the file's existing helpers for navigation and viewport setup where they exist. Replace canopy tests with:
+
+```ts
+test('homepage leads with truthful governance', async ({ page }) => {
+  await page.goto('/')
+  await expect(page.getByRole('heading', { name: /Govern token change/u })).toBeVisible()
+  await expect(page.locator('.proof-verdict')).toHaveText('PASS · 0 findings')
+  await expect(page.locator('.hero-install code')).toHaveText('npx primitree@next check')
+})
+
+test('proposal chips form a radiogroup with roving tabindex', async ({ page }) => {
+  await page.goto('/')
+  const group = page.getByRole('radiogroup', { name: 'Governance proposals' })
+  const chips = group.getByRole('radio')
+  await expect(chips).toHaveCount(4)
+  await expect(chips.first()).toHaveAttribute('aria-checked', 'true')
+  await expect(chips.first()).toHaveAttribute('tabindex', '0')
+  await expect(chips.nth(1)).toHaveAttribute('tabindex', '-1')
+})
+
+test('arrow keys move through proposals', async ({ page }) => {
+  await page.goto('/')
+  const group = page.getByRole('radiogroup', { name: 'Governance proposals' })
+  await group.getByRole('radio').first().focus()
+  await page.keyboard.press('ArrowRight')
+  await expect(group.getByRole('radio', { name: 'Compliant alias' })).toBeFocused()
+  await page.keyboard.press('End')
+  await expect(group.getByRole('radio', { name: 'Rename' })).toBeFocused()
+})
+
+test('layer violation reports the real policy result', async ({ page }) => {
+  await page.goto('/')
+  await page.getByRole('radio', { name: 'Layer violation' }).click()
+  await expect(page.locator('.proof-verdict')).toHaveText('BLOCK · PT1004')
+  await expect(page.locator('.proof-detail')).toHaveText(
+    'Layer semantic cannot reference layer component.'
+  )
+  await expect(page.locator('.proof-blocked')).toBeVisible()
+})
+
+test('compliant alias updates the emitted code', async ({ page }) => {
+  await page.goto('/')
+  await page.getByRole('radio', { name: 'Compliant alias' }).click()
+  await expect(page.locator('.proof-emitted')).toContainText('var(--primitives-color-green-500)')
+})
+
+test('diff terminal lists the rename blast radius', async ({ page }) => {
+  await page.goto('/')
+  await expect(page.locator('.terminal')).toContainText('removed semantic.color.bg.brand')
+  await expect(page.locator('.terminal')).toContainText(
+    'component.button.bg, component.focus.ring, component.nav.active.bg'
+  )
+})
+
+test('tree nodes never overflow their boxes', async ({ page }) => {
+  await page.goto('/')
+  const overflowing = await page.evaluate(() => {
+    const nodes = Array.from(document.querySelectorAll('.tree-node code'))
+    return nodes.filter(node => {
+      const parent = node.closest('.tree-node')
+      return (
+        parent !== null && node.getBoundingClientRect().right > parent.getBoundingClientRect().right
+      )
+    }).length
+  })
+  expect(overflowing).toBe(0)
+})
+
+test('homepage has no sticky scroll choreography', async ({ page }) => {
+  await page.goto('/')
+  const sticky = await page.evaluate(
+    () =>
+      Array.from(document.querySelectorAll('main *')).filter(
+        element => getComputedStyle(element).position === 'sticky'
+      ).length
+  )
+  expect(sticky).toBe(0)
+})
+```
+
+Preserve the untouched navigation, search, and contrast tests. Update the iPad and reduced-motion tests to assert the proof panel renders with four chips and a visible tree, with no `data-stage` attribute anywhere.
+
+- [ ] **Step 2: Run the e2e suite**
+
+```bash
+pnpm run test:e2e:install
+pnpm run test:e2e
+```
+
+Expected: PASS. The Playwright config starts the docs server per its existing `webServer` setup.
+
+- [ ] **Step 3: Commit**
+
+```bash
+pnpm exec prettier --write tests/e2e/docs-home-governance.spec.ts
+git add tests/e2e/docs-home-governance.spec.ts
+git commit -m "test(e2e): cover proposal panel, diff terminal, and static scroll"
+```
+
+---
+
+### Task 7: Full verification sweep
+
+**Files:** none new.
+
+- [ ] **Step 1: Run the full repo suite**
+
+```bash
+pnpm run build
+pnpm run test
+pnpm run check:brand
+node scripts/check-prose.mjs
+```
+
+Expected: all pass. `pnpm run test` includes `check-brand.test.mjs` and the docs tests.
+
+- [ ] **Step 2: Screenshot review**
+
+Capture desktop 1440x900, mobile 390x844, and desktop with reduced motion emulation, one screenshot per chip state. Review each against the spec section list: hero single column with install row, proof panel visible without scrolling tricks, terminal readable, config section without dead quadrants, facts row present.
+
+- [ ] **Step 3: Keyboard pass**
+
+Tab through the page in a real browser session: chips reachable with one tab stop, arrows move selection, copy buttons announce their labels, every focus state visible.
+
+- [ ] **Step 4: Commit any fixes and report**
+
+```bash
+git add -A
+git commit -m "fix(docs): polish from verification sweep"
+```
+
+Report results with screenshots and the final test output.

Subject: [PATCH 15/26] feat(docs): derive the landing token graph from
 @primitree/core

Expand the demo document to 15 tokens across three layers and project
nodes, edges, and per-proposal outcomes straight from the engine at build
time: a layer-skip violation with three PT1004 findings, a compliant
alias that resolves to the brand emerald, and a five-change rename. The
violation preset overlays the baseline wires so compliant references
stay visible under the red lanes, consumer counts come from the wires in
view, and the diff report renders single-line affected-token entries.
Read the published package version for the nav chip.

Subject: [PATCH 16/26] feat(docs): rebuild the homepage as the interactive
 token-graph instrument

Replace the proof-panel-and-tree layout with the approved landing
design: a hero install card with package-manager tabs and a row-wide
copy control, a live check command line with proposal chips, an SVG
token graph with hover-to-trace, click-to-inspect, hand-tuned wire
routing, red bypass lanes and the layer-skip tag, a tinted verdict bar
with a 700ms checking sweep, before/after review cards, a colorized
diff transcript, quickstart steps, the standards strip, and a compact
single-row footer. Every graph node is a keyboard-operable button with
a 44px hit target, the drift and blink loops stop under
prefers-reduced-motion, and a nav toggle switches the whole site
between the dark and light themes through next-themes. Schibsted
Grotesk and IBM Plex Mono replace Inter and Geist Mono, and Phosphor
icons replace Lucide in the chrome.

Subject: [PATCH 17/26] feat(brand): make the emerald design system the
 enforced brand

Swap the docs and playground palettes to the landing design's emerald
system, add the light-theme variable set to the contract, move the
retired Lichen hexes onto the former-color blocklist, and point the
favicons and README badge at the light-surface emerald. The brand
checker now accepts one approved value per theme for each variable,
requires the graph's structural classes and treatments, keeps the
glow, pointer-tracking, and blur bans, and permits the design's wire
drift and cursor loops. Playground buttons and filter chips drop their
pill radii for the 8px control shape, and primary actions fill with
the accent instead of white.

Subject: [PATCH 18/26] chore(prose): allowlist the landing design's verbatim
 copy

The approved homepage copy keeps 'what it reaches:', 'locally', and the
violation note's 'directly' and 'only' word for word, so the prose
gate carries exact-match exceptions for those four phrases.

Subject: [PATCH 19/26] test(e2e): cover the graph instrument, theme toggle,
 and emerald palette

Rewrite the homepage spec around the token graph: proposal chips retry
until hydration lands, the violation preset asserts the three red
lanes and the layer-skip tag, node clicks pin the inspect line, focus
traces the dependency chain, the install card switches package
managers, the graph scrolls in its own strip on compact screens, and a
new spec drives the light theme end to end. Palette assertions across
the shell and playground specs move to the emerald values, and the
contrast helper composites the new surface and tint colors.

Subject: [PATCH 20/26] docs(design): document the emerald system and token
 graph

Rewrite the design-system reference around the shipped brand: emerald
and forest tokens with the light overlay, Schibsted Grotesk and IBM
Plex Mono, uppercase kickers, 8px controls and 12px surfaces, the
sanctioned graph motion with its reduced-motion kill, and the token
graph's interaction contract.

 Primitree behaves like a botanical specimen crossed with a standards instrument: one rooted token change branches into policy, dependency, and build evidence.

+The palette favors deep forest surfaces; emerald marks active, governed, or ready-to-ship states. A light theme swaps every token through `data-theme='light'` on the root, with `#0B9464` as the light-surface emerald.
 
 ### Primary
 
-- **Electric Lichen:** The single active signal for selected branches, valid outcomes, primary actions, and the logo root.
-- **Root Black:** The page ground and deepest text-on-accent color.
+- **Emerald:** The single active signal for selected proposals, valid outcomes, primary actions, prompt glyphs, and added diff lines.
+- **Forest Black:** The page ground; **Emerald Ink** is the text color on emerald fills.
 
 ### Secondary
 
-- **Blocked Coral:** Reserved for policy violations and blocked changes. Never use it as decoration.
-- **Deep Lichen:** A quieter supporting signal for secondary graph structure and pressed states.
+- **Blocked Coral (#F87171):** Reserved for policy violations, blocked changes, and removed diff lines. Never use it as decoration.
+- **Changed Amber (#FBBF24):** Reserved for rename-affected consumers.
 
 ### Neutral
 
-- **Bone:** Primary text and high-contrast focus treatment.
-- **Ash:** Explanatory copy and secondary labels.
-- **Graphite:** Structural connectors and inactive controls.
-- **Canopy Black:** Raised evidence surfaces that must remain connected to the page rather than float above it.
+- **Bone:** Primary text and the high-contrast focus treatment.
+- **Sage:** Explanatory copy and secondary labels.
+- **Wire:** Idle graph connectors; **Rule** draws hairline borders and the hero dot grid.
+- **Panel:** Raised evidence surfaces that stay connected to the page.
 
-**The Signal Rule.** Electric Lichen occupies less than ten percent of a screen. Its rarity makes governance state legible at a glance.

-**The Consequence Rule.** Coral means blocked or unsafe. It never means “interesting,” “new,” or “hovered.”

-- **Headline** (540, fluid 32–72px, 1 line-height): Section arguments and major proof statements.
-- **Title** (540, 20–28px, 1.15 line-height): Named governance branches and evidence outcomes.
-- **Body** (430, 17px, 1.65 line-height): Explanations capped near 65 characters per line.

role=button because HTML buttons cannot exist inside SVG.

Subject: [PATCH 22/26] fix(docs): keep landing transcripts truthful to the CLI

Review findings from the PR bots, verified against the CLI: check only
evaluates policy, so the install card and quickstart now run primitree
build for the wrote line; the proposal id moves into a shell comment
because check has no --proposal flag; the quickstart layers excerpt
carries the roots and values fields config validation requires; the
copy control reports copied only after the clipboard write succeeds;
and the rename comparison names the stale reference that would block
instead of implying the passing rename blocks anything.

Subject: [PATCH 25/26] refactor(styles): earn the cascade without important
 overrides

Unlayered author rules already out-rank the layered utility styles the
important flags were fighting, so the icon controls, sidebar border,
and hover treatments drop them entirely. The two places important is
load-bearing stay and say why: the scroll-lock rule beats
react-remove-scroll's inline styles and the reduced-motion kill switch
must out-rank every animation. Descending-specificity orderings are
untangled, the redundant reduced-motion blocks are gone, and the
version chip hides below 430px so the compact header never overflows.

Subject: [PATCH 26/26] chore(lint): clear the remaining repository lint
 warnings

Replace non-null assertions in the core and hooks tests with a must()
narrowing helper, resolve the graph runtime's three assertions with
real guards that reuse the existing unknown-token and unresolved-value
diagnostics, use template literals and literal keys where the linter
asked, and import path through the node: protocol in the hooks Vite
config. biome lint now reports zero errors and zero warnings.
