Fix EFFECT keyword format across all documentation and scripts - priority
modifier (+/=/–) is required but was missing from examples.
**Documentation fixes:**
- doc/HOWTO.md: Added missing + to EFFECT example
- doc/RECIPE.md: Added priority modifiers to examples
- tools/shadertoy/README.md: Fixed test path, clarified workflow
- tools/shadertoy/convert_shadertoy.py: Updated output instructions
**New automation guide:**
- doc/EFFECT_WORKFLOW.md: Complete step-by-step checklist for AI agents
- Exact file paths and line numbers
- Common issues and fixes
- Asset ID naming conventions
- CMakeLists.txt dual-section requirement
- Test list instructions (post_process_effects vs scene_effects)
**Integration:**
- CLAUDE.md: Added EFFECT_WORKFLOW.md to Tier 2 (always loaded)
- doc/AI_RULES.md: Added "Adding Visual Effects" quick reference
- README.md: Added EFFECT_WORKFLOW.md to documentation list
**CMakeLists.txt:**
- Disabled incomplete cube_sphere_effect.cc (ShaderToy conversion WIP)
**Timeline:**
- Commented out incomplete CubeSphereEffect
- Removed obsolete constructor argument

Two bugs causing black screen when CNN post-processing activated:
1. Framebuffer capture timing: Capture ran inside post-effect loop after
ping-pong swaps, causing layers 1+ to capture wrong buffer. Moved
capture before loop to copy framebuffer_a once before post-chain starts.
2. Missing uniforms update: CNNEffect never updated uniforms_ buffer,
leaving uniforms.resolution uninitialized (0,0). UV calculation
p.xy/uniforms.resolution produced NaN, causing all texture samples
to return black. Added uniforms update in update_bind_group().
Files modified:
- src/gpu/effect.cc: Capture before post-chain (lines 308-346)
- src/gpu/effects/cnn_effect.cc: Add uniforms update (lines 132-142)
- workspaces/main/shaders/cnn/cnn_layer.wgsl: Remove obsolete comment
- doc/CNN_DEBUG.md: Historical debugging doc
- CLAUDE.md: Reference CNN_DEBUG.md in historical section

Extract detailed examples and untriaged tasks to on-demand docs.
Created BACKLOG.md, ARCHITECTURE.md, CODING_STYLE.md, TOOLS_REFERENCE.md.
Reduces always-loaded token budget by 30% while preserving all information.

Reduced context from 31.6k to ~10k tokens by preventing Tier 3 design docs
from being auto-loaded. Only Tier 1 (critical) and Tier 2 (technical ref)
files loaded by default. Load design docs on-demand with Read tool.

Major documentation reorganization to reduce AI agent context size by ~58%
and establish sustainable maintenance practices.
## File Moves (Root → doc/)
- Move COMPLETED.md (new), HANDOFF*.md, *_ANALYSIS.md, *_SUMMARY.md to doc/
- Keep only 5 essential files in root: CLAUDE.md, GEMINI.md, PROJECT_CONTEXT.md, TODO.md, README.md
- Result: Clean root directory with clear project essentials
## New Documentation
- doc/CONTEXT_MAINTENANCE.md: Comprehensive guide for keeping context clean
- 4-tier hierarchy (Critical/Technical/Design/Archive)
- Maintenance schedules (after milestones, monthly, on-demand)
- Size targets, red flags, workflows
- Monthly checklist template
- doc/COMPLETED.md: Historical archive of completed milestones
- Moved "Recently Completed" sections from TODO.md and PROJECT_CONTEXT.md
- Detailed completion history (February 4-7, 2026)
- Frees up ~200 lines from active context
## Agent Config Updates
- CLAUDE.md: Restructured with 4-tier hierarchy
- Tier 1: Critical (always loaded) - 3 files
- Tier 2: Technical (always loaded) - 3 files
- Tier 3: Design (on-demand) - 9 files
- Tier 4: Archive (rarely) - 10 files
- Clear usage instructions for on-demand loading
- GEMINI.md: Same tier structure + Gemini-specific state snapshot
- Consistent with CLAUDE.md hierarchy
- Preserved agent-specific context
## Content Optimization
- PROJECT_CONTEXT.md: Removed verbose milestones (~160 lines)
- Replaced with concise "Current Status" summary
- Points to COMPLETED.md for history
- TODO.md: Removed Task #51 detailed plan (~200 lines)
- Marked Task #51 as completed
- Kept only active/next tasks
## Impact
- Context size: 70K → 29K tokens (58% reduction)
- Root directory: 15 → 5 files (67% cleaner)
- Tier 1-2 files: 7,329 words (well under 10K target)
- Documented maintenance process for sustainability
## Files Changed
Modified: CLAUDE.md, GEMINI.md, PROJECT_CONTEXT.md, TODO.md
New: doc/COMPLETED.md, doc/CONTEXT_MAINTENANCE.md
Moved: 10 technical docs from root to doc/
