# NodeBench Redesign — Architecture & Journey

> **Status (2026-05-04):** Live behind the standalone `/redesign` route. React app is the source of truth; the locked HTML board (`.tmp/parity-nodebench-locked-memo/.../proposed-design-views.html`) is now a static dossier that mirrors the React surfaces.

This document records the full redesign — what was built, why, where it lives, and how to promote it into the production cockpit.

---

## 1 · The brief

The redesign exists to operationalize the entity-intelligence workspace thesis:

> Chat is the front door. Reports are memory. Notebooks are the working artifact. The graph is the navigation layer. Everything compounds — public research is cached, private notes stay private.

**Inputs**
- Long-form spec the user pasted (treated as the parity-studio decomposition output since `HomenShum/parity-studio` resolves 404 publicly)
- `nexu-io/open-design` repo — Claude.ai warm-paper system + 139 design-system DESIGN.md docs + 62 SKILL.md frontmatter
- `linear-app`, `cohere`, `notion`, `raycast` DESIGN.md (open-design catalog)
- The locked design board at `.tmp/parity-nodebench-locked-memo/ui_kits/nodebench-locked-memo-layer/proposed-design-views.html` (originally the source, now reflects the React redesign)

**Constraints**
- Don't disturb the live cockpit (1086-line `CockpitLayout.tsx`) — additive only
- Preserve the 5-tab IA: `Home · Reports · Chat · Inbox · Me`. Workspace is a separate surface, not a sixth tab
- Preserve NodeBench terracotta `#d97757` accent
- "No provider names in UI" — model picker shows tiers, not engine names

## 2 · Design language synthesis

| Element | Source | Token |
|---|---|---|
| Page canvas (warm white) | Notion + Claude | `--rd-paper: #faf9f7` |
| Ink (deep, slightly warm) | Notion | `--rd-ink: #1a1916` |
| Whisper border | Notion | `--rd-line: rgba(21,20,15,0.10)` |
| Multi-layer shadows | Notion | `--rd-shadow-md` (4 layers) |
| Hero radius (Pulse / Active event) | Cohere | `--rd-r-hero: 22px` |
| Compact card radius | Linear | `--rd-r-md: 12px` |
| Display weight 510 | Linear | `font-weight: 510` |
| OpenType `cv01 ss03` | Linear | `font-feature-settings` |
| Dark mode depth | Raycast + Linear | multi-layer ring shadows |
| Brand accent | NodeBench | `#d97757` (preserved) |

The cohesive feel: **calm enterprise paper in light mode, precision instrument in dark mode**. Never pure white, never pure black, always a hint of warmth.

---

## 4 · Surface-by-surface design decisions

### Home (Pulse)

**Spec-driven hierarchy**: hero composer above the fold → memory pulse metrics → today's intelligence → active event → recent reports.

The hero composer card is the focal point. The page ANSWERS the question "what changed worth my attention" without forcing the user to scroll into a dashboard.

**Active event hero** uses a soft gradient (`linear-gradient(135deg, var(--rd-accent-tint), var(--rd-paper))`) — calm, not the harsh blue→terracotta of the original HTML mock. The locked design board's hard gradient was rejected because it broke the calm-paper feel of the rest of the app.

### Reports (Reusable memory library)

Compact-by-default. Brief/Explore/Chat triple-action footer per card. Sticky filter row with status tabs (`All / Verified / Watching / Needs review`) and density toggle (`Compact / Grid / List`).

**Status pills** use a Linear-style achromatic + minimal-hue palette (green / blue / amber). The "Verified" pill is `#1f7a3a` not screamy emerald — quiet authority over alarm.

### Chat (Live operating surface)

Single-column conversation. Each turn is either:
- **User bubble** — right-aligned, accent-tint background
- **Answer packet** — full hero card with status strip + short answer (display font) + why it matters + evidence (citation `[n]` chips) + risks + next action (accent-tinted CTA card) + collapsible "How we got this answer" trace

The status strip carries the **routed-tier badge** (`Routed: Auto`) so the reader knows which engine produced the answer without exposing provider names.

**No provider names in main UI.** They appear only in the trace section's step labels (`Synthesise · Gemini 3 Pro · grounded`).

### Inbox (Attention queue)

Per-item layout: glyph (amber for needs-confirmation, accent for approval, blue for watchlist, green for automation, muted for unassigned) + body + detected-entity chips + confidence bar (color-graded: green ≥85%, accent ≥65%, amber otherwise) + action stack.

Filter chips along the top, no decision-item kicker shouting (rejected the `kicker → 72% CONFIDENCE` pattern from the HTML mock — too noisy at scale).

### Me (Personal Context Notebook)

Three-card runtime row pinned at top:
- **How NodeBench sees you** — editable lens summary
- **Existing runtime** — pointer to `product.me profile` Convex contracts
- **Editable source** — pointer to `USER.md` markdown (terracotta-highlighted)

Below: TipTap-style toolbar (`H2 / B / I / UL / 1. / '' / Undo / Redo`) + `Saved to Convex` save-state pill that flips to amber `Saving…` on edit.

Per-section permission pill stack: each section has its own visibility toggles (`chat / reports / exports`, `global pref / teachability`, `free first / approve paid`, `private / diff required`). Toggling propagates to the save-state.

**Patch inbox** card (terracotta-tinted): suggested memory edits with `Accept / Edit diff / Reject`. **Agent implementation hooks** card: 4 deeplink-style buttons to `RichNotebookEditor`, `teachability tools`, `operatorProfile contract`, `OpenClaw audit`. **Safety policy** card: 3 checkbox switches.

Footer preserves the locked Me shell (Plan + credits, Integrations).

### Workspace (Deep intelligence surface)

6 tabs: `Brief · Cards · Notebook · Sources · Chat · Map`.

**Cards** is the headline. CardStack rules:
- Max 3 active columns
- Persistent breadcrumb + ← Back
- Promote-to-root from any card
- Older columns collapse into a `+N hops` chip
- Each card carries: type badge · pills · summary · why it matters · key facts · claims (with citation `[n]` + status dot) · next-hop list · footer actions (sources / Promote / Pin / Add to notebook / Ask)

**Map** is intentionally a placeholder static SVG — Sigma.js / Graphology would mount here in production. Cards drive comprehension; Map shows orientation. Sources prove claims.

### Mobile

Capture-first. The headline mobile pattern is the **capture ack card** — when a user records or types a quick capture, a terracotta-tint card appears with detected entities + `Edit / Move / Open card` actions. This is the entire mobile UX thesis: capture without mode-switching.

Bottom 5-tab nav is locked (never collapsed, never reordered). Composer dock pinned above tab bar uses the same `UniversalComposer` as desktop. Bottom sheets handle Sources / Graph / Entity context — no new pages on phone.

---

## 5 · The composer (Claude/ChatGPT pattern)

The composer went through three iterations:

1. **v1** — Tier pills as a 4-radio row below the textarea. Worked but felt like a form, not a chat input.
2. **v2** — Added attach/paste/voice icons inline. Better, but tier row still chunky.
3. **v3 (shipped)** — Single rounded card. Top row: context chip (left) + tier dropdown (right). Center: textarea. Bottom: `+` menu (left) + mic + keyboard hint + send circle (right). Matches Claude / ChatGPT.

### Public API

```typescript
import { UniversalComposer, DEFAULT_TIERS, type RouterTier } from "@/features/redesign/components/UniversalComposer";

<UniversalComposer
  contextLabel="Asking about: Orbital Labs"
  onContextChange={() => {/* open context picker */}}
  onSubmit={(text, tier) => {/* dispatch */}}
  tier="auto"                       // controlled (or omit for uncontrolled)
  onTierChange={setTier}
  tiers={DEFAULT_TIERS}             // override to add/remove tiers
/>
```

### Tier router (model picker, no provider names)

```
Auto                    Memory-first · NodeBench picks the right engine    ~1.8s
Quick answer            Fast pass · cached sources only                    ~800ms
Deep dive [$]           Refresh sources · paid call may be required        ~7.5s
Compare across list [$] Run on every entity in this view                   ~12s
```

The dropdown popover anchors **upward** so it never overflows when the composer is bottom-docked. Esc + click-outside both dismiss.

The `[$]` badge marks paid-call tiers. It never auto-charges — paid calls require approval via the Me page's safety policy when budget hits zero.

---

## 6 · Mobile responsive strategy

`useViewportMobile()` watches `(max-width: 760px)`. Below that breakpoint, `RedesignShell` mounts `MobileShell` instead of the desktop `Rail + RightInspector` grid. Workspace stays desktop-only (the Map + 3-column CardStack don't compress).

A floating **Phone** FAB lets you preview the mobile shell on a desktop browser without resizing — useful for design review against the locked HTML board.

---

## 7 · Theming

Light is default. Dark mode is a `data-redesign-theme="dark"` override on the shell, set by the floating theme FAB. Tokens in dark mode shift to a Linear/Raycast blend:
- Canvas `#0f1011`
- Ink `#f7f8f8`
- Accent `#e88f6e` (warmer terracotta for the dark medium)
- Multi-layer ring shadows mimic Raycast's keyboard-key depth

`prefers-reduced-motion` disables all transitions inside the redesign scope.

---

## 8 · Verification matrix (run before any change)

| Check | Command / URL |
|---|---|
| TypeScript clean | `npx tsc --noEmit --pretty false` |
| Surfaces render | `npm run dev` → http://localhost:5200/redesign |
| Per-surface DOM signals | `data-redesign-surface="/redesign/<surface>"` |
| Composer popovers | Tier dropdown opens upward, `+` menu opens upward, Esc dismisses |
| CardStack max | Drill 3 hops on `/redesign/workspace` Cards tab → 3 columns + breadcrumb showing 3 segments |
| Mobile shell | Phone FAB toggles `MobileShell`; bottom-tab nav present; capture-ack visible on `/redesign/chat` |
| Dark mode | Theme FAB swaps to dark; accent shifts to `#e88f6e` |
| Sitemap | `public/sitemap.xml` lists all 6 `/redesign*` routes |

---

## 9 · Promotion path (when ready)

The redesign is currently behind the `/redesign` standalone route. To promote to the default cockpit:

1. **Phase A — Discoverability** (low risk)
   - Add a `Try the new design →` banner inside the existing landing page that links to `/redesign`
   - Keep the cockpit as default
   - Track click-through rate
2. **Phase B — Opt-in default** (medium risk)
   - Add a user-preference toggle (`useRedesignShell`) gated behind a Convex feature flag
   - Authenticated users see the redesign by default; cockpit available via `?surface=cockpit`
   - Migration risk: existing keyboard shortcuts, command-palette entries, `viewRegistry` IDs all need parity
3. **Phase C — Full migration** (high risk)
   - Replace `CockpitLayout` mounts in App.tsx with `RedesignShell`
   - Wire fixtures to live Convex queries (`useQuery(api.domains.operations.inbox.getPageWithInboxNotifications)` etc.)
   - Port WorkspaceModeToggle / WorkspaceModePane / FinancialOperatorOverlay into the new shell
   - Move the global `FastAgentPanel` overlay behind the redesign's right-rail surface
   - Sunset the `/redesign` standalone route

Don't skip phases. Each one validates the layer below.

## 9.5 · Reports as TipTap notebooks (the core architectural piece)

> **Every report is a TipTap document. Three writers — user, chat, agent — share one editor.**

This is the architectural piece that makes "Reports are memory" load-bearing. A report isn't a saved answer; it's a living notebook that the user edits inline, that chat appends to when an agent answers a question, and that autonomous agents patch with new claims and refreshed sources.

### Component shape

```
Convex `reports.notebookHtml`  ──┐
                                  ├─►  <ReportNotebookEditor>     (TipTap)
Chat thread (this report) ───────┤          ▲
Agent runtime (this report) ─────┘          │
                                       imperative refs:
                                  applyChatPatch(NotebookPatch)
                                  applyAgentPatch(NotebookPatch)
```

[components/ReportNotebookEditor.tsx](../../src/features/redesign/components/ReportNotebookEditor.tsx) — wraps `@tiptap/react` with StarterKit, exposes a toolbar (H1/H2/H3 · B/I/S · UL/1./quote · custom +Claim/+Follow-up/+Source · Undo/Redo), and an imperative `forwardRef` API so parents can write into the document.

[components/ReportNotebookView.tsx](../../src/features/redesign/components/ReportNotebookView.tsx) — full report surface: editor + audit feed + pending-patches sidebar + simulate-writers demo controls.

### The `NotebookPatch` contract

```typescript
interface NotebookPatch {
  html: string;                          // TipTap parses + inserts at cursor (or end)
  afterBlockId?: string;                  // optional anchor (production: block ids)
  source: "chat" | "agent" | "user";      // drives save-state pill + audit log
  label: string;                          // shown in audit feed
}
```

`applyChatPatch(patch)` → save-state flips to `Chat is editing` (accent pill) → patch lands → returns to `Saved to Convex`.
`applyAgentPatch(patch)` → save-state flips to `Agent is editing` (blue pill) → patch lands → audit entry recorded.

### Custom block types (showcase via `data-block` attributes; production via TipTap Node extensions)

| Block | Markup | When written |
|---|---|---|
| Heading 1 / 2 / 3 | StarterKit | User editor or agent structuring |
| Paragraph / lists / blockquote | StarterKit | Standard prose |
| **Claim** | `<div data-block="claim" data-status="verified|review|rejected" data-cite="N">…<span data-claim-source>…</span></div>` | Agent extracts a citable assertion |
| **Follow-up** | `<div data-block="follow-up" data-due="tomorrow|this-week|next-week">…</div>` | User or agent adds an action item |
| **Source list** | `<div data-block="source-list"><span data-source-list-label>…</span><ol>…</ol></div>` | Agent rolls up sources used |

Production Node extensions (next step): `Node.create({ name: "claim", group: "block", parseHTML: …, renderHTML: …, addAttributes: () => ({ status, cite }) })`.

### Read-only public-share mode

`ReportNotebookEditor` accepts `readOnly: boolean`. Toggle on to flip:
- Editor `editable: false`
- Save-state pill becomes `Read-only · public share`
- Toolbar buttons disabled

Production: gated by `reports.publicShare` flag + a `share/<token>` route that fetches a redacted document.

### Pending-patch flow (the core trust pattern)

Agents don't write directly to the notebook by default. They emit a `NotebookPatch` to a queue. The user sees a card in the right sidebar with:
- Source badge (`agent` blue / `chat` accent / `user` muted)
- Label (one-line description)
- Preview (diff summary)
- Accept · Reject · Edit diff

Accepting calls `applyAgentPatch` (the same imperative API). Rejecting drops the patch and logs the rejection in the audit feed.

This pattern matches the "Agent implementation hooks" + "Safety policy" sections in the Me page — privacy/budget/connector writes always require diff review.

### Wiring locations

- **Workspace Notebook tab** — embeds `<ReportNotebookView reportId={...} embedded />` so the editor occupies the tab body without its own header
- **Standalone `/redesign/reports/:id`** — full-shell report surface with header + edit/share/export controls + sidebar
- **Reports list "Brief" action** — navigates to `/redesign/reports/:id` (the new notebook view)
- **Reports list "Explore"/"Chat" actions** — still navigate to `/redesign/workspace?report=<id>&tab=<cards|chat>`

### Production migration checklist

1. Replace fixture `reportNotebookHtml[reportId]` with `useQuery(api.reports.getNotebookHtml, { id })`
2. Debounce `editor.getHTML()` into `useMutation(api.reports.upsertNotebook, { id, html })` — 500 ms tail
3. Promote each `data-block` attribute pattern to a TipTap Node extension so the schema validates
4. Add a slash command extension (typing `/` opens a menu of block types)
5. Add a bubble menu for "Ask AI to improve this selection" (the spec's last notebook use case)
6. Wire chat surface "Save to notebook" CTA on each agent answer to `editorRef.current?.applyChatPatch(...)`
7. Wire agent runtime: a Convex action subscribes to `notebookPatchQueue`, the client renders pending patches in the sidebar, accept calls `applyAgentPatch`
8. Public share: server returns redacted HTML for `/share/:token`; mount `<ReportNotebookEditor readOnly />`

### Why TipTap (not contentEditable, not a custom doc model)

- StarterKit covers 80% of report content (headings, lists, blockquote, marks)
- `Node.create()` lets us promote `data-block="claim"` etc. into validated, schema-bound nodes when production wants them
- ProseMirror's transaction model gives us atomic, reversible patches — agents can't half-write a block
- `editor.getHTML()` round-trips through Convex with no custom serializer
- Already shipped: the project lists 24 `@tiptap/*` extensions in package.json (StarterKit, table, mention, placeholder, list, link, image, …) — the production editor is a config away

## 9.6 · Live agent QA loop (Gemini 3.1 Pro Preview)

> **Run**: `npm run qa:redesign` — judges every persona scenario via real Gemini calls. **Avg score moves** as you fix things.

The redesign is graded by Gemini 3.1 Pro Preview against an **Obsidian + Roam + Notion + Karpathy** rubric. Seven persona scenarios cover the realistic adoption surface:

| Persona | Workflow | Rubric emphasis |
|---|---|---|
| `banker_diligence` | Pre-meeting tear-sheet on a private mid-market borrower | citation_clarity · claim_status_visibility · agent_review_loop · scannability |
| `founder_pre_meeting` | 7-minute scan of a vendor before a partnership call | notion_parity · keyboard_efficiency · discoverability · comment_affordance |
| `researcher_long_form` | 3,000-word distilled essay with backlinks | typography_quality · backlinks_loop · long_form_readability · export_options |
| `teacher_relocation` | School + district research, non-technical user | zero_jargon · first_impression_clarity · affordance_visibility · share_flow |
| `operator_pipeline` | CRM rollup memo with CSV export | export_breadth · freshness_visibility · audit_legibility · crm_compatibility |
| `karpathy_learner` | Distilled derivation, opinionated, hand-cited (Karpathy-style) | keyboard_latency · writing_focus · slash_menu_speed · markdown_shortcuts |
| `obsidian_vault_keeper` | Personal entity vault with `[[backlinks]]` and graph navigation | wikilinks_consistency · backlinks_completeness · audit_attribution · graph_view |

Each persona is judged on **8 emphasized dimensions out of 30+ rubric items** — see [scripts/qa/personas.ts](../../scripts/qa/personas.ts) for the full catalog.

### How the harness works

[scripts/qa/redesignAgentQa.ts](../../scripts/qa/redesignAgentQa.ts):

1. **Capture** — Playwright opens `BASE_URL/redesign/reports/rep_orbital` at 1440×900, lets TipTap mount, then full-page-screenshots + grabs `.rd-notebook__content` innerText
2. **Judge** — sends multimodal request to `gemini-3.1-pro-preview` with: persona context + tasks + success criteria + emphasized rubric + screenshot + innerText. Forces JSON-schema response.
3. **Fall back** — if Pro fails, retries with `gemini-3-flash-preview` → `gemini-3.1-flash-lite-preview` → `gemini-2.5-flash-lite` (same chain as `convex/domains/evaluation/dogfood/screenshotQa.ts`)
4. **Aggregate** — writes `findings.md` (markdown report with per-persona sections + global P0/P1/P2/P3 buckets + dimension heatmap) and `results.json` (machine-readable)

Output: `.tmp/redesign-qa/<ISO-timestamp>/{findings.md, results.json, *.png}`

### Pi-AI parity

The harness reads `process.env.GEMINI_API_KEY` (or `GOOGLE_AI_API_KEY` / `GOOGLE_GENERATIVE_AI_API_KEY`) — same env contract as the existing Convex pi-ai integration in [convex/domains/agents/adapters/google/googleInteractionsAdapter.ts](../../convex/domains/agents/adapters/google/googleInteractionsAdapter.ts) and [convex/domains/evaluation/dogfood/screenshotQa.ts](../../convex/domains/evaluation/dogfood/screenshotQa.ts). Drop-in promotable to a Convex action when desired.

### Run modes

```bash
# Full sweep — 7 personas, ~3 minutes wall-clock
npm run qa:redesign

# Fast sweep — 2 personas (banker + karpathy), ~1 minute
npm run qa:redesign:fast

# Custom subset
npx tsx scripts/qa/redesignAgentQa.ts --personas banker_diligence,operator_pipeline,obsidian_vault_keeper

# Different base URL
BASE_URL=https://www.nodebenchai.com npx tsx scripts/qa/redesignAgentQa.ts
```

### Score trajectory (8 passes, autonomous loop)

| Pass | Avg | P0 | P1 | Top change applied | Notable Δ |
|---|---|---|---|---|---|
| 1 | 65 | 0 | 2 | baseline (2 personas) | banker 75, karpathy 55 |
| 2 | 68 | 0 | 7 | Entity chips → neutral · Accept → green · Saved pill subtle · `Cmd+\\` Focus · `[N]` citations | banker **75 → 91** (+16) |
| 3 | **70** | 0 | 9 | Persistent toolbar removed · BubbleMenu on selection · Save pill into chrome | karpathy **60 → 75** (+15), founder P0 cleared |
| 4 | 69 | 0 | 8 | Clickable BlockHandle · Undo/Redo · Graph link · sidebar collapse chevron | obsidian **70 → 85** (+15) — Graph found |
| 5 | 70 | 0 | 7 | Always-visible page addons · plain-English sidebar (Suggestions / Recent activity) · larger heading tracking | banker **88**, obsidian **88** |
| 6 | **72** | 0 | 7 | Faint always-on block-handle dots · hide `rep_orbital` jargon | obsidian **88**, karpathy **78** |
| 7 | 68 | 0 | 9 | Wikilink `[[Entity]]` brackets visible · Placeholder ext | teacher -25 (raw brackets noise), karpathy -10 |
| 8 | 69 | 0 | 5 | Brackets hover-only · stronger addon contrast · CSS handle text removed | teacher **47 → 75** (+28) |

**Trajectory peak: 72 / 100 at pass 6.** Subsequent passes oscillate 68–72. Convergence reached: 3 passes within ±3 of rolling avg.

**Per-persona peaks** (achieved at different passes — single static UI can't hit all simultaneously):

| Persona | Peak | At pass | Tension with |
|---|---|---|---|
| banker_diligence | **91** | 2 | karpathy (more chrome ↔ less chrome) |
| founder_pre_meeting | 60 | 6 | karpathy (visible affordances ↔ hidden) |
| researcher_long_form | 70 | 6 | — |
| teacher_relocation | **75** | 8 | obsidian (no brackets ↔ brackets) |
| operator_pipeline | **82** | 3 | — |
| karpathy_learner | **78** | 6 | banker / founder (clean ↔ visible) |
| obsidian_vault_keeper | **88** | 4–5 | teacher (brackets ↔ no brackets) |

### What converged + what's structurally blocked

**Converged (delivered)**
- P0 count → 0 (reliably)
- Banker, obsidian, operator, karpathy all peaked above 75
- Clickable BlockHandle, BubbleMenu, slash menu, citation chips, Focus mode, Graph link, plain-English sidebar all shipped

**Structurally blocked by persona divergence**
- **Block-handle visibility**: founder wants visible always; karpathy wants invisible. Hover-only is the compromise that scores worst with both.
- **Wikilink brackets**: obsidian wants `[[Foo]]` always; teacher reads them as raw markup. Hover-only delivered (current state).
- **Sidebar density**: banker/operator want it open; karpathy wants it gone. `Cmd+\` toggle delivered, but agent QA judges from a static screenshot of the default state.

**Resolution to break through 72 cap**
The loop revealed a real product question: **NodeBench needs a chrome-density mode preference** (Notion-style "Default" vs Obsidian-style "Power-user" vs Karpathy-style "Focus only"). A single static UI cannot satisfy all 7 personas simultaneously — the rubric weights are antagonistic by design. With a 3-mode toggle, each mode could optimize for ~3 personas, lifting the per-mode average to 80+.

That's a future structural change beyond the scope of this loop.

The score is **honest** — Gemini does not know about the codebase, only what it sees in the screenshot + innerText. When a fix moves the score, the fix worked.

### Remaining themes from the latest run

- **founder_pre_meeting (30/100)** — persistent WYSIWYG toolbar still implies a "legacy editor". Production fix: replace with a floating bubble menu on selection + slash-menu-only block insert.
- **comment_affordance** — no `Add comment` ghost button or block-level comment bubbles in the right margin.
- **affordance_visibility** — `UL` button label is HTML jargon; non-technical users won't decode it. Replace with an icon or `List`.
- **graph_view** — Obsidian users can't reach the relationship map from the notebook view.
- **workspace_navigation** — `Sources` tab not 1-click reachable from the rail.

These are the next slate to ship; each one moves the score 3-8 points based on the rubric weights.

## 10 · Known gaps

- **Convex wiring** — every surface uses `fixtures.ts`. Production needs to swap to `useQuery` hooks.
- **CardStack persistence** — drilled-path state is component-local. Should sync to `?path=ship_demo,orbital,alex` for shareable URLs.
- **Map surface** — placeholder static SVG. Production needs Sigma.js / Graphology.
- **Sources tab in Workspace** — hardcoded list. Should pull from the active report's source array.
- **Auth boundary** — redesign route is currently public (renders before the auth wrapper). Either move under `<Authenticated>` or render demo data when unauthenticated. (The cockpit handles this via guest mode.)
- **A11y sweep** — focus rings + skip links + keyboard nav implemented in primitives, but no axe audit run yet.
- **Performance budget** — no lazy boundaries inside `RedesignShell`. Surface components could be lazy-loaded if bundle size matters.

## 11 · The journey (chronological)

1. **Decompose** — User pasted parity-studio decomposition spec. `HomenShum/parity-studio` resolves 404 publicly so the spec was treated as the decomposition output.
2. **Mine open-design** — Parallel agent extracted tokens + skill catalog + 139 design systems from `nexu-io/open-design`. Recommended `linear-app + cohere + raycast + notion + stripe` as design language sources.
3. **Survey NodeBench** — Parallel agent inventoried `CockpitLayout` (5-region grid: StatusStrip + WorkspaceRail + ActiveSurfaceHost + Right rail + TraceStrip) and identified the 12 highest-leverage gaps vs the spec.
4. **Build initial redesign** — `/redesign` standalone route with Home / Reports / Chat / Inbox / Me / Workspace surfaces under a clean tokens layer.
5. **Add mobile + Personal Context Notebook** — User flagged the locked HTML board's Me view + mobile spec. Added MobileShell with capture-ack pattern; rewrote MeSurface with TipTap + permission pills + patch inbox + agent hooks.
6. **Add model router** — User pointed out the missing model selector on chat. Added tier router (Auto / Quick answer / Deep dive `$` / Compare across list `$`) — surfaces intent, hides provider names per spec.
7. **Refactor composer to Claude/ChatGPT pattern** — User: "it should feel like chatgpt or claude chat composer". Tier pills became a dropdown anchored to top-right; `+` menu anchored to bottom-left; send becomes an icon-only circle.
8. **Map to locked HTML board** *(reverted)* — Attempted to mirror the older HTML mock's tokens (blue→terracotta gradients, bolder pills, etc.). User reversed direction: "build what we had from redesign route to replace what was on the html".
9. **Reverse direction (current state)** — React reverted to the modern Claude/Linear/Notion blend. The locked HTML rewritten as a static dossier mirroring the React route.

## 12 · How to extend

### Add a new tier to the router

```typescript
// surfaces/ChatSurface.tsx (or wherever the composer mounts)
import { UniversalComposer, DEFAULT_TIERS, type RouterTierOption } from "@/features/redesign/components/UniversalComposer";

const CUSTOM_TIERS: RouterTierOption[] = [
  ...DEFAULT_TIERS,
  { id: "research", label: "Research thread", hint: "Multi-day deep dive", estimateMs: 86_400_000, paidCall: true },
];

<UniversalComposer tiers={CUSTOM_TIERS} ... />
```

### Add a new surface

1. Create `src/features/redesign/surfaces/MySurface.tsx`
2. Mount it in `RedesignShell.tsx` under a new `surface` value
3. Add a `Rail.tsx` nav entry
4. Add a `pathToSurface()` mapping
5. Add a sitemap entry in `public/sitemap.xml`

### Override tokens for a sub-tree

Tokens are scoped to `[data-redesign]`. To create a variant, nest a child with override custom properties:

```jsx
<div data-redesign style={{ '--rd-accent': '#5e6ad2' /* Linear indigo */ }}>
  ...
</div>
```

The synthesis is intentional — no single source dominates. NodeBench is its own thing, but it borrows the disciplined parts of each.
