stripMarkdownFences duplicated locally in pdf-renderer — wallpaper-renderer does not export it and creating a shared util was not planned
buildPdfSystemPrompt uses a switch with 4 distinct system prompt variants (report/invoice/api-docs/one-pager) — each has structurally different instructions for the LLM
archiver installed now so Plans 02-03 can use it without an extra install step
PDF system prompts always include 'Use only inline CSS in a <style> block. No external URLs, no <link> tags, no <script> tags. Use web-safe system fonts' constraint
Playwright page.pdf() with format A4, printBackground true, 20mm margins — standard PDF output configuration

Phase 43 Plan 01: PDF Renderer Foundation Summary

Playwright HTML-to-PDF renderer for 4 document types (report/invoice/api-docs/one-pager) with PdfDocumentBundle/BrandKitBundle types and content-job-runner wiring

Performance

  • Duration: ~5 min
  • Started: 2026-04-04T22:43:00Z
  • Completed: 2026-04-04T22:45:11Z
  • Tasks: 2
  • Files modified: 5

Accomplishments

  • Created pdf-renderer.ts with renderPdfDocument: LLM generates HTML via puterChatComplete, Playwright renders to PDF, returns PdfDocumentBundle JSON
  • Added PdfDocumentBundle and BrandKitBundle interfaces to types.ts and updated ContentBundle union
  • Installed archiver + @types/archiver for Plans 02-03 ZIP operations
  • Wired "pdf-document" jobType in content-job-runner switch with dynamic import pattern
  • 6 unit tests pass covering all 4 docTypes + browser cleanup + system prompt variation

Task Commits

Each task was committed atomically:

  1. Task 1: Install archiver, add bundle types, create pdf-renderer with tests - 7c7394bf (feat)
  2. Task 2: Wire pdf-document jobType into content-job-runner - 16023234 (feat)

Files Created/Modified

  • server/src/services/renderers/pdf-renderer.ts - renderPdfDocument (Playwright HTML-to-PDF) + buildPdfSystemPrompt
  • server/src/__tests__/pdf-renderer.test.ts - 6 unit tests with playwright-core/puter-inference mocks
  • server/src/services/renderers/types.ts - PdfDocumentBundle and BrandKitBundle interfaces added, ContentBundle union updated
  • server/src/services/content-job-runner.ts - "pdf-document" case added to renderContent switch
  • server/package.json - archiver + @types/archiver added

Decisions Made

  • stripMarkdownFences was duplicated locally in pdf-renderer.ts rather than importing from wallpaper-renderer.ts because wallpaper-renderer does not export this helper. This follows the existing project pattern where it was also not exported.
  • buildPdfSystemPrompt generates structurally distinct prompts per docType — report gets formal section structure, invoice gets financial table layout, api-docs gets endpoint reference format, one-pager gets visual impact layout.

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

  • Plan 43-02 (brand-kit renderer) can now import BrandKitBundle from types.ts and use archiver for ZIP output
  • Plan 43-03 (document UI panel) can import PdfDocumentBundle and use the pdf-document jobType
  • All 6 tests pass, TypeScript clean for modified files
