All three follow the same async pattern — POST /content-jobs returns 202 + jobId, SSE stream delivers progress, result assets land in the `generated` namespace. + +**Mermaid rendering** on the server cannot use the browser mermaid library directly via jsdom (mermaid 11 requires real browser SVG APIs that jsdom does not implement). The solution is to use Playwright's already-installed Chromium binary (`~/.cache/ms-playwright/chromium-1217/chrome-linux64/chrome`) to run a headless page that calls `mermaid.render()`. This avoids adding new binary dependencies — the Chromium is already downloaded for e2e tests. SVG output is sanitized with DOMPurify (already in server deps). PNG is produced by `sharp(svgBuffer, { density: 144 })` following the exact same pattern as `renderOrgChartPng` in `org-chart-svg.ts`. + +**Icon generation** uses the LLM to produce SVG path markup from a text description, then SVGO to clean and optimize the output. The job produces a JSON bundle stored as the primary asset, containing N SVG strings plus metadata. PNG variants are generated server-side for the bundle. This sidesteps the "N icons = N separate assets" problem since `content_jobs.resultAssetId` is a single UUID. + +**The theme engine** uses `culori` (needs to be added as a server dependency — not yet installed there) for all OKLCH math, with `wcag-contrast` for AA validation. "Apply theme" extends the existing `nexus-settings.json` persistence and `ThemeContext` to support a custom token map injected into `document.documentElement` CSS variables. + +**Primary recommendation:** Add `culori`, `@resvg/resvg-js`, `svgo`, and `wcag-contrast` to server deps. Add `playwright-core` to server deps for headless Mermaid rendering using the already-installed Chromium.

Extend its Zod schema with an optional `customTheme` field. When applied, the server stores the palette and the UI's `ThemeContext` reads it on startup. + +```typescript +// Extend nexusSettingsSchema in nexus-settings.ts +const paletteRoleSchema = z.object({ + name: z.string(), + dark: z.object({ oklch: z.string(), hex: z.string(), wcagAA: z.boolean() }), + light: z.object({ oklch: z.string(), hex: z.string(), wcagAA: z.boolean() }), +}); + +export const nexusSettingsSchema = z.object({ + mode: z.enum(NEXUS_MODES).default("both"), + voiceEnabled: z.boolean().default(false), + voiceMode: z.enum(VOICE_MODES).default("text"), + telegramToken: z.string().optional(), + piperBinaryPath: z.string().optional(), + whisperBinaryPath: z.string().optional(), + customTheme: z.object({ // NEW + seedHex: z.string(), + palette: z.array(paletteRoleSchema), + }).optional(), +}); +``` + +The `ThemeContext` already calls `applyTheme(theme)` which sets CSS variables on `document.documentElement`. Add `applyCustomTheme(palette, variant)` that injects the palette tokens into the root. On initial load, check if `nexusSettings.customTheme` is set and apply it. Expose "custom" as a Theme option in the THEME_META map. + +### Anti-Patterns to Avoid + +- **Running mermaid directly in jsdom server-side:** Mermaid 11 requires `getBBox()`, `SVGMatrix`, and `foreignObject` support. jsdom does not implement these — rendering will silently produce empty or malformed SVG. +- **Storing N icons as N separate content_jobs:** Creates orphan accumulation. Store one JSON bundle asset per icon-set job containing all SVG strings. +- **HSL as intermediate in palette generation:** STATE.md explicitly forbids this. Use OKLCH throughout. No `hsl()` conversions anywhere in the palette pipeline. +- **Injecting theme CSS into `document.documentElement` during preview:** Bleeds into nav/sidebar. Use `.nexus-theme-preview` container scope via `container.style.setProperty()`. +- **Blocking HTTP on render:** All three renderers must go through the async job queue. No synchronous render endpoints. +- **Launching a new browser instance per request without cleanup:** Playwright `browser.close()` must be called in a `finally` block.

Document the required env var in server startup. + +**Warning signs:** `Error: browserType.launch: Failed to launch chromium because executable doesn't exist` in server logs. + +### Pitfall 2: Mermaid `click` Directive Strip — Incomplete Regex + +**What goes wrong:** A simple regex like `click\s+\w+` only strips `click NodeId` but Mermaid supports `click NodeId "url"` and `click NodeId call functionName()`. Incomplete strip leaves partial directives that break rendering. + +**How to avoid:** Use a line-oriented strip — remove any line starting with `click` after normalization: +```typescript +const CLICK_LINE_RE = /^\s*click\s+.*/gim; +const INIT_BLOCK_RE = /%%\{[\s\S]*?\}%%/g; +const cleaned = source.replace(INIT_BLOCK_RE, "").replace(CLICK_LINE_RE, ""); +``` + +**Warning signs:** Mermaid render errors for diagrams containing click interactions. + +### Pitfall 3: culori ESM-only Import in CommonJS Context + +**What goes wrong:** culori 4.0.2 ships `"."` pointing to `"./src/index.js"` (ESM) as primary export. If the server's TypeScript `moduleResolution` is CommonJS-style, `import { oklch } from "culori"` may fail at runtime. + +**Why it happens:** The server uses `tsx` which is ESM-compatible, but if `server/tsconfig.json` uses `"moduleResolution": "node"` (pre-Node16), the ESM conditional export may not be honored. + +**How to avoid:** Verify `server/tsconfig.json` `moduleResolution` setting. If it's `"node"` (not `"node16"` or `"bundler"`), use the explicit CJS path: `import culori from "culori/require"`. If it's `"node16"` or `"nodenext"`, standard `import { oklch } from "culori"` works. Check during Wave 0. + +**Warning signs:** `ERR_REQUIRE_ESM` or module resolution errors at `tsx` startup. + +### Pitfall 4: LLM SVG Output — Invalid viewBox + +**What goes wrong:** LLMs generating SVG icons sometimes produce `viewBox` values inconsistent with path coordinates, or omit the `xmlns` attribute. Icons appear clipped or invisible. + +**How to avoid:** After SVGO optimization, validate the output: (1) `viewBox` attribute is present — normalize to `"0 0 24 24"` if absent; (2) `xmlns="http://www.w3.org/2000/svg"` is present for standalone SVG files; (3) at least one ``, ``, or `` element exists. Return an error to the user with copy "Render failed — {detail}. Try again." if validation fails. + +**Warning signs:** Empty white squares in the icon grid; zero byte SVG files. + +### Pitfall 5: ThemePreviewPanel Re-render Loop + +**What goes wrong:** The theme preview updates CSS properties, which triggers a React re-render, which reads the CSS properties, which triggers another update. + +**How to avoid:** Use `useRef` for the container element and set CSS properties imperatively (`container.style.setProperty()`), not via React state. The debounce fires outside the React render cycle. Only the palette data (from server) is stored in React state; CSS injection is a side effect in `useEffect`. + +### Pitfall 6: content_jobs.resultAssetId is Single — Multi-file Output + +**What goes wrong:** Diagram jobs produce SVG + PNG. Icon sets produce N SVG files. Storing each as a separate asset and pointing `resultAssetId` to only one breaks the download flow. + +**How to avoid:** Store all output as a single JSON bundle asset (`application/json`). The UI parses the bundle to offer individual file downloads. The bundle schema is discriminated by `type` field (`"diagram-bundle"`, `"icon-set-bundle"`, `"theme-palette-bundle"`). + +### Pitfall 7: Browser Instance Leak in diagram-renderer + +**What goes wrong:** If the mermaid render page throws or times out, `browser.close()` never runs and the Chromium process is orphaned. + +**How to avoid:** Always wrap the `page`/`browser` lifecycle in `try { ... } finally { await browser.close(); }`. Set a render timeout (15s) so the process does not hang indefinitely. Add a startup-time browser pool or singleton if latency becomes a concern (single-user context, so one browser at a time is acceptable). + +--- + +## Code Examples + +### Culori OKLCH Parse and Derive (culori 4.0.2) + +```typescript +import { oklch, formatHex, converter } from "culori"; + +const toOklch = converter("oklch"); +const seed = toOklch("#1e66f5"); +// seed = { mode: "oklch", l: ~0.45, c: ~0.22, h: ~262 } + +// Derive a background role: +const bg = formatHex({ mode: "oklch", l: 0.14, c: 0.010, h: seed.h ?? 0 }); +// bg = "#191727" (approximately) +``` + +### WCAG Contrast Check (wcag-contrast 3.0.0) + +```typescript +import wcagContrast from "wcag-contrast"; + +const ratio = wcagContrast.hex("#89b4fa", "#1e1e2e"); // ~8.5 +const passesAA = ratio >= 4.5; // true +const passesAAA = ratio >= 7.0; // true +``` + +### DOMPurify in Node (jsdom + dompurify — existing server deps) + +```typescript +import { JSDOM } from "jsdom"; +import DOMPurify from "dompurify"; + +const { window } = new JSDOM(""); +const purify = DOMPurify(window as unknown as Window); +const cleanSvg = purify.sanitize(rawSvg, { USE_PROFILES: { svg: true } }); +``` + +### Sharp SVG to PNG (Established pattern from org-chart-svg.ts) + +```typescript +import sharp from "sharp"; + +const pngBuffer = await sharp(Buffer.from(svgString), { density: 144 }) + .resize(targetWidth, targetHeight) + .png() + .toBuffer(); +``` + +### @resvg/resvg-js SVG to PNG (Primary alternative — no librsvg) + +```typescript +import { Resvg } from "@resvg/resvg-js"; + +const resvg = new Resvg(svgString, { dpi: 144, fitTo: { mode: "width", value: 1200 } }); +const pngBuffer = resvg.render().asPng(); +``` + +### SVGO SVG Optimization (svgo 4.0.1) + +```typescript +import { optimize } from "svgo"; + +const result = optimize(rawSvgString, { plugins: ["preset-default"] }); +const optimizedSvg = result.data; +``` + +### Mermaid Security Strip + +```typescript +const INIT_BLOCK_RE = /%%\{[\s\S]*?\}%%/g; +const CLICK_LINE_RE = /^\s*click\s+.*/gim; + +function stripUnsafeDirectives(source: string): { cleaned: string; stripped: boolean } { + const withoutInit = source.replace(INIT_BLOCK_RE, ""); + const withoutClick = withoutInit.replace(CLICK_LINE_RE, ""); + const cleaned = withoutClick.trim(); + return { cleaned, stripped: cleaned !== source.trim() }; +} +``` + +--- + +## State of the Art + +| Old Approach | Current Approach | When Changed | Impact | +|--------------|------------------|--------------|--------| +| HSL color math for UI themes | OKLCH via culori | CSS Color 4 spec (2022+) | Perceptually uniform; gradients do not go gray in the middle | +| Mermaid CLI (mmdc) for server rendering | Playwright headless + mermaid.js | mermaid 10+ dropped jsdom compat | No new Chromium download; reuses already-installed browser | +| Manual WCAG contrast formula | wcag-contrast library | WCAG 2.1 (2018) | Correct sRGB linearization handling | +| SVG to PNG via sharp(svgBuffer) | @resvg/resvg-js (Rust) | librsvg dependency unreliable across platforms | Self-contained; consistent output quality | + +**Deprecated/outdated:** +- `mermaid` in jsdom: mermaid 8/9 could work with jsdom+dagre, but mermaid 10+ requires real browser SVG APIs.

Should `playwright-core` be added to `server/package.json` `dependencies` or is the monorepo context sufficient? + - Recommendation: Add `playwright-core@1.58.2` to `server/package.json` `dependencies` for explicitness and correctness. Use `executablePath` from env var `PLAYWRIGHT_BROWSERS_PATH` or the known cache location. + +2. **Icon LLM prompt quality vs style coherence** + - What we know: LLMs can generate SVG paths; consistency across a set (ICON-02: "cohesive visual style") requires a strong system prompt with explicit constraints + - What's unclear: Which local model is active via Ollama? SVG generation quality varies significantly by model size and training. + - Recommendation: Use a structured system prompt with explicit rules (24x24 viewBox, stroke-width=1.5, currentColor fill, no text elements); include existing icon names from lucide-react as style reference; validate output passes SVGO before storing; surface model quality issues to user via the generic error message. + +3. **Theme "Apply to Nexus" — in-memory vs server persistence** + - What we know: `ThemeContext` reads from localStorage; `nexus-settings.json` persists on server. The UI-SPEC toast says "Reload to see full effect." + - Recommendation: Do both — write to server settings (PATCH /nexus/settings with customTheme), AND update ThemeContext in-memory immediately so the change is visible without reload. Toast message "Reload to see full effect" covers components that don't observe ThemeContext. + +--- + +## Environment Availability + +| Dependency | Required By | Available | Version | Fallback | +|------------|------------|-----------|---------|----------| +| Node.js | All | ✓ | v20.20.2 | — | +| Playwright Chromium binary | Mermaid server rendering | ✓ | Chromium 1217 (playwright 1.58.2) at ~/.cache/ms-playwright | Cannot render server-side Mermaid; fall back to client-only | +| sharp | SVG to PNG (fallback path) | ✓ | 0.34.5 in server node_modules | @resvg/resvg-js is primary | +| @resvg/resvg-js | SVG to PNG (primary) | ✗ not installed yet | 2.6.2 on npm; linux-x64-gnu confirmed | sharp(svgBuffer, {density:144}) as fallback | +| culori | OKLCH palette engine | ✗ not installed yet | 4.0.2 on npm | No fallback — mandated by STATE.md | +| wcag-contrast | WCAG AA validation | ✗ not installed yet | 3.0.0 on npm | Manual formula (fragile; not recommended) | +| svgo | LLM SVG cleanup | ✗ not installed yet | 4.0.1 on npm | Deliver unoptimized SVG (larger, possible LLM artifacts) | +| playwright-core | Server headless Chromium | ✗ not in server package.json | 1.58.2 on npm (must match installed Chromium) | Cannot render Mermaid server-side | +| dompurify | Mermaid SVG sanitization | ✓ | 3.3.2 in server node_modules | — | +| jsdom | DOMPurify DOM provider | ✓ | 28.1.0 in server node_modules | — | + +**Missing dependencies with no fallback:** +- `culori` — OKLCH theme engine is blocked without it; mandated by STATE.md +- `playwright-core` — Mermaid server-side rendering requires a headless browser + +**Missing dependencies with fallback:** +- `@resvg/resvg-js` — `sharp` is available as fallback for SVG to PNG (established org-chart pattern) +- `svgo` — icons can be delivered unoptimized as fallback (not ideal but functional) +- `wcag-contrast` — can be computed manually as fallback (fragile) + +--- + +## Validation Architecture + +### Test Framework + +| Property | Value | +|----------|-------| +| Framework | vitest 3.x (monorepo root config at `/opt/nexus/vitest.config.ts`; server and UI included) | +| Config file | `/opt/nexus/vitest.config.ts` | +| Quick run command | `pnpm --filter server exec vitest run` | +| Full suite command | `pnpm test:run` (from `/opt/nexus`) | + +### Phase Requirements to Test Map + +| Req ID | Behavior | Test Type | Automated Command | File Exists?

User submits prompt → Button shows spinner + label "Generating…" (disabled). Primary CTA label changes in-place; no separate loading overlay. +2. SSE events arrive → Progress bar (shadcn `progress`, primary fill) animates from 0→100%. Progress bar sits directly below the CTA button, full-width of the panel. +3. On `ready`: progress bar disappears (fade out 200ms), result panel slides down (height animation 300ms ease-out). Button reverts to "Generate again" (secondary variant). +4. On `error`: progress bar fills destructive color, error message appears below bar ("Render failed — {detail}. Try again."), Button reverts to "Generate Diagram" (primary, enabled). +5. Reconnect on SSE disconnect: silent reconnect, no user-facing error unless render ultimately fails. + +### Mermaid Source Collapsible + +- Default state: collapsed. +- Trigger label: "View Mermaid source" (chevron right). Expanded: "Hide source" (chevron down). +- Height transition: 250ms ease. +- Textarea is editable. "Re-render diagram" Button (secondary, xs size) appears at bottom-right of expanded panel when source is modified. +- Security stripping is server-side. No client-side feedback needed beyond standard error state. + +### Theme Live Preview + +- Preview updates on every palette recalculation (debounced 150ms after seed color change). +- No full-page refresh. CSS variables injected via JS into `.nexus-theme-preview` scope only. +- "Apply to Nexus" triggers ThemeApplyConfirmDialog before writing to settings. +- After apply: toast notification "Theme applied. Reload to see full effect." (not destructive; use default toast variant). + +### Icon Selection + +- Checkbox appears on card hover (top-left corner, 16px). On coarse pointer: always visible. +- Multi-select: selecting any card shows the DiagramDownloadBar at the bottom of the panel (sticky, z-index above scroll content). +- Deselect all: "Clear selection" link in the sticky bar. + +--- + +## Copywriting Contract + +| Element | Copy | +|---------|------| +| Diagram CTA | "Generate Diagram" | +| Diagram generating state | "Generating…" | +| Diagram re-render CTA | "Re-render diagram" | +| Diagram download (SVG) | "Download SVG" | +| Diagram download (PNG) | "Download PNG" | +| Diagram source toggle (collapsed) | "View Mermaid source" | +| Diagram source toggle (expanded) | "Hide source" | +| Diagram attach confirmation | "Diagram attached — SVG + PNG" | +| Icon CTA | "Generate Icons" | +| Icon generating state | "Generating…" | +| Icon download (selected) | "Download selected ({N})" | +| Icon empty state heading | "No icons yet" | +| Icon empty state body | "Describe what you need and we'll generate a cohesive set." | +| Theme CTA | "Generate Palette" | +| Theme generating state | "Generating…" | +| Theme apply CTA | "Apply to Nexus" | +| Theme apply dialog heading | "Apply theme?" | +| Theme apply dialog body | "This will update your Nexus color scheme.
