added patterns
ContentStudio: useCompany().selectedCompanyId passed as companyId to all content panels
useContentJob pattern: submit -> SSE progress -> done -> fetch asset URL -> JSON.parse bundle
DiagramSourcePanel dirty state: set on change (not blur) for reliable test assertions
Server-sanitized SVG rendered via dangerouslySetInnerHTML (mirrors MarkdownBody.tsx mermaid pattern)
TDD test cleanup: @testing-library/react cleanup() called in afterEach to prevent DOM accumulation

Phase 41 Plan 04: ContentStudio Page — Diagrams and Icons UI Summary

ContentStudio page with Diagrams and Icons tabs fully functional: prompt+type selector, generate button, SSE progress, SVG preview with download, collapsible source editor (TDD-tested), icon grid with selection and bulk download bar

Performance

  • Duration: ~7 min
  • Started: 2026-04-04T20:48:00Z
  • Completed: 2026-04-04T20:55:27Z
  • Tasks: 2
  • Files created/modified: 10

Accomplishments

  • ContentStudio page registered at /:companyId/content-studio with 3-tab layout (Diagrams, Icons, Themes)
  • DiagramGeneratePanel: full generate flow with prompt, type selector, generate button with spinner, progress bar, SVG preview, stripped-directive notice, empty state, error state
  • DiagramPreview: server-sanitized SVG rendered inside paperclip-mermaid container, SVG and PNG download buttons
  • DiagramSourcePanel: collapsible Mermaid source editor with copy button (aria-label), re-render button on dirty, height transition
  • DiagramSourcePanel.test.tsx: 6 passing tests covering DIAG-03 requirements
  • IconGeneratePanel: description + style + count selectors, generate button, progress, empty/error states
  • IconResultGrid: responsive 4-col/2-col grid, per-icon checkboxes (aria-labeled), hover download row
  • IconDownloadBar: sticky download bar with download selected count, format selector, clear selection

Task Commits

  1. Task 1: ContentStudio page + Diagram UI components + DiagramSourcePanel test - 095ba9ba (feat)
  2. Task 2: Icon UI components (generate panel, result grid, download bar) - cf7784ae (feat)

Files Created/Modified

  • ui/src/pages/ContentStudio.tsx - Tabbed ContentStudio page with Diagrams, Icons, Themes tabs
  • ui/src/components/DiagramGeneratePanel.tsx - Full diagram generation flow
  • ui/src/components/DiagramPreview.tsx - SVG preview with paperclip-mermaid container + download buttons
  • ui/src/components/DiagramSourcePanel.tsx - Collapsible Mermaid source editor
  • ui/src/components/DiagramSourcePanel.test.tsx - 6 TDD tests for DIAG-03 collapsible source behavior
  • ui/src/components/IconGeneratePanel.tsx - Icon generation panel
  • ui/src/components/IconResultGrid.tsx - Responsive icon grid with selection checkboxes and download row
  • ui/src/components/IconDownloadBar.tsx - Sticky download bar for selected icons
  • ui/src/types/content-bundles.ts - DiagramBundle/IconSetBundle/ThemePaletteBundle type contracts
  • ui/src/App.tsx - Added content-studio route and ContentStudio lazy import

Decisions Made

  • dirty state in DiagramSourcePanel is set onChange rather than onBlur: in jsdom test environment, onBlur fires before the state update from onChange propagates, making the Re-render diagram button not appear reliably in tests.
  • content-bundles.ts created in ui/src/types/ to give the UI its own type contract for parsing bundle JSON from content job assets. Matches server-side RenderResult union types from Plan 41-01.
  • Themes tab intentionally shows placeholder: Theme UI is in scope for Plan 41-06 (ThemeEngine UI), not Plan 41-04.

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Added cleanup() to DiagramSourcePanel.test.tsx afterEach

  • Found during: Task 1 (GREEN phase test run)
  • Issue: @testing-library/react does not auto-cleanup between tests in vitest jsdom environment without explicit cleanup() call. Multiple test instances accumulated in the DOM, causing getByText("View Mermaid source") to find multiple elements.
  • Fix: Added cleanup() import and call in afterEach hook.
  • Files modified: ui/src/components/DiagramSourcePanel.test.tsx
  • Commit: 095ba9ba

2. [Rule 1 - Bug] Moved dirty state to onChange instead of onBlur in DiagramSourcePanel

  • Found during: Task 1 (GREEN phase tests for Re-render button failing)
  • Issue: onBlur handler checking editedSource !== mermaidSource fires correctly in browser, but in jsdom test environment with fireEvent.change + fireEvent.blur, the state from onChange has not yet been applied when onBlur runs synchronously.
  • Fix: Set dirty state directly in onChange handler by comparing new value to mermaidSource prop.
  • Files modified: ui/src/components/DiagramSourcePanel.tsx
  • Commit: 095ba9ba

Total deviations: 2 auto-fixed (Rule 1 - bugs found during TDD GREEN phase) Impact on plan: No scope change. Both fixes are in the test infrastructure and component implementation to ensure reliable test assertions.

Known Stubs

  • ui/src/pages/ContentStudio.tsx Themes tab: shows "Theme engine coming soon." — intentional placeholder. Theme UI is out of scope for Plan 41-04 and will be implemented in Plan 41-06.

User Setup Required

None — UI components are static React components consuming existing hooks and APIs.

Next Phase Readiness

  • Plans 41-05 and 41-06 can now reference ContentStudio.tsx for Themes tab implementation
  • DiagramSourcePanel test pattern (@testing-library/react + cleanup() in afterEach) established for future component tests
  • content-bundles.ts type contracts ready for Theme palette bundle UI parsing in Plan 41-06
