## Summary

I've completed **task-18: Cross-Cutting Synthesis and Resolution Strategy**:

### What was accomplished:
1. **Created scaffolding directory** at `/tmp/crew-perspective-9/`

2. **Synthesized findings** from completed audit tasks:
   - Aggregated 45+ hardcoded threshold locations
   - Categorized by type: thresholds (45+), symbol lists (3), date ranges (5), output paths (3), worker counts (2)
   - Identified components: Python core, Rust tools, Rust core tests, ClickHouse

3. **Created comprehensive synthesis document** at `docs/symbol-registry-synthesis.md`:
   - Findings matrix by category and component
   - Dependency analysis (immediate wiring vs. registry enhancement)
   - 4-phase implementation plan:
     - Phase 1: Quick Wins (Python helper functions)
     - Phase 2: Rust Tool Integration (env vars)
     - Phase 3: Build-Time Constants
     - Phase 4: Registry Enhancement
   - Migration strategies and verification commands

4. **Created sub-tasks** as specified:
   - task-30: Create comprehensive findings matrix
   - task-31: Draft implementation plan  
   - task-32: Identify quick-win fixes

5. **Committed** the synthesis document to the repository (commit `23f9c44`)

The task depends on its subtasks (30, 31, 32) which are now being worked on by other agents (ZenXenon, EpicJaguar).
