dc27435ca1 M2 complete: Recommendation engine + similar shaders + tag affinities
Feed ranking (anonymous users):
- score * 0.6 + recency * 0.3 + random * 0.1
- Recency uses 72-hour half-life decay
- 10% randomness prevents filter bubbles

Feed ranking (authenticated users):
- score * 0.5 + recency * 0.2 + tag_affinity * 0.2 + random * 0.1
- Tag affinity built from engagement history:
  - Upvoted shader tags: +1.0 per tag
  - Downvoted: -0.5 per tag
  - Dwell >10s: +0.3, >30s: +0.6
- Over-fetches 3x candidates, re-ranks with affinity, returns top N

Similar shaders endpoint:
- GET /api/v1/feed/similar/{shader_id}
- Finds shaders with overlapping tags
- Ranks by tag overlap count, breaks ties by score
- MCP tool: get_similar_shaders

Fix: PostgreSQL text[] && varchar[] type mismatch
- Used type_coerce() instead of cast() for ARRAY overlap operator
- Affects both shaders search-by-tags and similar-by-tags queries

1047a1f5fe Versioning, drafts, resizable editor, My Shaders, 200 seed shaders
Architecture — Shader versioning & draft system:
- New shader_versions table: immutable snapshots of every edit
- Shaders now have status: draft, published, archived
- current_version counter tracks version number
- Every create/update creates a ShaderVersion record
- Restore-from-version endpoint creates new version (never destructive)
- Drafts are private, only visible to author
- Forks start as drafts
- Free tier rate limit applies only to published shaders (drafts unlimited)

Architecture — Platform identity:
- System account 'fractafrag' (UUID 00000000-...-000001) created in init.sql
- is_system flag on users and shaders
- system_label field: 'fractafrag-curated', future: 'fractafrag-generated'
- Feed/explore can filter by is_system
- System shaders display distinctly from user/AI content

API changes:
- GET /shaders/mine — user workspace (drafts, published, archived)
- GET /shaders/{id}/versions — version history
- GET /shaders/{id}/versions/{n} — specific version
- POST /shaders/{id}/versions/{n}/restore — restore old version
- POST /shaders accepts status: 'draft' | 'published'
- PUT /shaders/{id} accepts change_note for version descriptions
- PUT status transitions: draft→published, published→archived, archived→published

Frontend — Editor improvements:
- Resizable split pane with drag handle (20-80% range, smooth col-resize cursor)
- Save Draft button (creates/updates as draft, no publish)
- Publish button (validates, publishes, redirects to shader page)
- Version badge shows current version number when editing existing
- Owner detection: editing own shader vs forking someone else's
- Saved status indicator ('Draft saved', 'Published')

Frontend — My Shaders workspace:
- /my-shaders route with status tabs (All, Draft, Published, Archived)
- Count badges per tab
- Status badges on shader cards (draft=yellow, published=green, archived=grey)
- Version badges (v1, v2, etc.)
- Quick actions: Edit, Publish, Archive, Restore, Delete per status
- Drafts link to editor, published link to detail page

Seed data — 200 fractafrag-curated shaders:
- 171 2D + 29 3D shaders
- 500 unique tags across all shaders
- All 200 titles are unique
- Covers: fractals (Mandelbrot, Julia sets), noise (fbm, Voronoi, Perlin),
  raymarching (metaballs, terrain, torus knots, metall/glass),
  effects (glitch, VHS, plasma, aurora, lightning, fireworks),
  patterns (circuit, hex grid, stained glass, herringbone, moiré),
  physics (wave interference, pendulum, caustics, gravity lens),
  minimal (single shapes, gradients, dot grids),
  nature (ink, watercolor, smoke, sand garden, coral, nebula),
  color theory (RGB separation, CMY overlap, hue wheel),
  domain warping (acid trip, lava rift, storm eye),
  particles (fireflies, snow, ember, bubbles)
- Each shader has style_metadata (chaos_level, color_temperature, motion_type)
- Distributed creation times over 30 days for feed ranking variety
- Random initial scores for algorithm testing
- All authored by 'fractafrag' system account, is_system=true
- system_label='fractafrag-curated' for clear provenance

Schema:
- shader_versions table with (shader_id, version_number) unique constraint
- HNSW indexes on version lookup
- System account indexes
- Status-aware feed indexes

365c033e0e Fix Docker Compose startup issues
- Rename EngagementEvent.metadata → event_metadata (SQLAlchemy reserved name)
- Replace passlib with direct bcrypt usage (passlib incompatible with bcrypt 5.0)
- Fix renderer Dockerfile: npm ci → npm install (no lockfile)
- Fix frontend Dockerfile: single-stage, skip tsc for builds
- Remove deprecated 'version' key from docker-compose.yml
- Add docker-compose.dev.yml for data-stores-only local dev
- Add start_period to API healthcheck for startup grace

05d39fdda8 M0: Foundation scaffold — Docker Compose, DB schema, FastAPI app, all service stubs
Track A (Infrastructure & Data Layer):
- docker-compose.yml with all 7 services (nginx, frontend, api, mcp, renderer, worker, postgres, redis)
- docker-compose.override.yml for local dev (hot reload, port exposure)
- PostgreSQL init.sql with full schema (15 tables, pgvector indexes, creator economy stubs)
- .env.example with all required environment variables

Track A+B (API Layer):
- FastAPI app with 10 routers (auth, shaders, feed, votes, generate, desires, users, payments, mcp_keys, health)
- SQLAlchemy ORM models for all 15 tables
- Pydantic schemas for all request/response types
- JWT auth middleware (access + refresh tokens, Redis blocklist)
- Redis rate limiting middleware
- Celery worker config with job stubs (render, embed, generate, feed cache, expire bounties)
- Alembic migration framework

Service stubs:
- MCP server (health endpoint, 501 for all tools)
- Renderer service (Express + Puppeteer scaffold, 501 for /render)
- Frontend (package.json with React/Vite/Three.js/TanStack/Tailwind deps)
- Nginx reverse proxy config (/, /api, /mcp, /renders)

Project:
- DECISIONS.md with 11 recorded architectural decisions
- README.md with architecture overview
- Sample shader seed data (plasma, fractal noise, raymarched sphere)
