phase provides
43-01 archiver package installed, BrandKitBundle type in types.ts, content-job-runner switch pattern
brand-renderer.ts — renderBrandKit function with 7-step orchestration
brand-kit jobType wired in content-job-runner switch
7 unit tests covering all BrandKitBundle fields
43-03 (brand kit UI panel will import BrandKitBundle type and use brand-kit jobType)
added patterns
7-step brand kit orchestration
spec extraction → logo SVG → avatar rasterization → social images → email+letterhead templates → guidelines PDF → ZIP
Single Playwright browser instance per brand kit job (open once, use for PDF, try/finally close)
Social images as SVG templates (colored rect + embedded logo as data URI), NOT LLM-generated — keeps fast and predictable
archiver streaming ZIP via Writable sink, resolve on sink finish event (Pattern 3 from RESEARCH.md)
stripMarkdownFences duplicated locally (same approach as pdf-renderer.ts — wallpaper-renderer doesn't export it)

Social images are SVG templates (colored rect + embedded logo) rather than LLM-generated — keeps generation fast and deterministic
Playwright browser opened once per brand kit job for guidelines PDF — reuses browser instance to avoid spawning multiple processes
pnpm install run as deviation fix — archiver was in package.json (added by Plan 01) but node_modules not populated in this worktree

Phase 43 Plan 02: Brand Kit Renderer Summary

Full brand identity kit renderer orchestrating logo SVG, 5 avatar sizes, 5 social platform images, email signature HTML, letterhead HTML, guidelines PDF, and ZIP packaging via archiver

Performance

  • Duration: ~4 min
  • Started: 2026-04-04T22:47:34Z
  • Completed: 2026-04-04T22:50:30Z
  • Tasks: 2
  • Files modified: 3

Accomplishments

  • Created brand-renderer.ts with renderBrandKit: 7-step orchestration producing a complete BrandKitBundle
  • extractBrandSpec: LLM JSON extraction with fallback defaults
  • generateLogoSvg: LLM SVG generation cleaned via validateAndCleanSvg (SVGO)
  • rasterizeAvatars: sharp rasterizes logo to 5 PNG sizes (512/256/128/64/32)
  • generateSocialImages: SVG template per platform (colored bg + logo), 5 platforms
  • generateTemplates: 2 parallel LLM calls for email signature + letterhead HTML
  • generateGuidelinesPdf: Playwright HTML→PDF with single shared browser instance
  • buildZip: archiver streaming ZIP with correct folder structure (brand-kit/logo/, brand-kit/social/, brand-kit/templates/, brand-kit/guidelines.pdf)
  • 7 unit tests pass covering all BrandKitBundle fields and ZIP magic bytes verification
  • Wired brand-kit jobType in content-job-runner switch with dynamic import

Task Commits

Each task was committed atomically:

  1. Task 1: Create brand-renderer with orchestrated sub-renders and ZIP packaging - cd753612 (feat)
  2. Task 2: Wire brand-kit jobType into content-job-runner - e059a0da (feat)

Files Created/Modified

  • server/src/services/renderers/brand-renderer.ts - renderBrandKit with 7-step orchestration
  • server/src/__tests__/brand-renderer.test.ts - 7 unit tests with all required mocks
  • server/src/services/content-job-runner.ts - brand-kit case added to renderContent switch

Decisions Made

  • Social images use SVG templates (colored rect + base64-embedded logo) rather than LLM-generated artwork — this is fast, deterministic, and always on-brand
  • Playwright browser is opened once for the brand kit job (for the guidelines PDF step) using a try/finally block — avoids spawning multiple browser processes for what is a single-shot job
  • archiver was already in package.json from Plan 01 but not installed in this worktree — ran pnpm install as a deviation fix

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] archiver package not installed in node_modules

  • Found during: Task 2 (tsc --noEmit check)
  • Issue: archiver and @types/archiver were added to server/package.json by Plan 01 but pnpm install had not been run in this worktree, causing TS2307 "Cannot find module 'archiver'"
  • Fix: Ran pnpm install at the monorepo root — resolved 65 packages including archiver and @types/archiver
  • Files modified: none (lockfile already had archiver)

Known Stubs

None — all BrandKitBundle fields are populated with real data (LLM-generated or sharp-rasterized).

Issues Encountered

  • archiver not installed in worktree node_modules (fixed by pnpm install)

User Setup Required

None - no external service configuration required beyond PUTER_AUTH_TOKEN already documented.

Next Phase Readiness

  • Plan 43-03 (document/brand UI panel) can now use brand-kit jobType and BrandKitBundle type
  • All 7 tests pass, TypeScript clean for all modified files

Phase: 43-documents-branding Completed: 2026-04-04
