Based on my work for the **Symbol Registry Integration Points Audit**, I've completed the following:

## Summary

### What I Did:
1. **Created scaffolding directory** at `/tmp/crew-registry/`
2. **Reviewed symbol_registry.py** - Found 11 query functions currently exposed:
   - `get_symbol_entries()`, `get_thresholds_for_symbol()`, `get_symbol_market()`, `get_effective_start_date()`, `get_registered_symbols()`, `resolve_market()`, `validate_symbol_registered()`, `validate_and_clamp_start_date()`, `filter_pairs_by_registry()`, `get_all_symbol_threshold_pairs()`, `get_transitions()`

3. **Audited compat/availability.py** - ✅ Correctly uses the registry via `get_symbol_entries()` and `get_thresholds_for_symbol()`

4. **Identified Missing Registry Helper Functions**:
   - `get_default_threshold()` - Needed to eliminate hardcoded 250 values across codebase
   - `get_tier1_symbols()` - Needed to consolidate scattered TIER1_SYMBOLS constants
   - `get_priority_symbols()` - Needed to unify priority symbol definitions

5. **Created comprehensive audit report** at `/tmp/crew-registry/registry_audit.md`

### Key Findings:
- Only 1 enabled symbol in registry (BTCUSDT) out of 30 registered
- Multiple hardcoded values should query registry: `DEFAULT_THRESHOLD=250`, `TIER1_SYMBOLS`, `_PRIORITY_SYMBOLS`
- compat/availability.py is a good example of correct registry integration

The task system shows a mismatch (task-8 is already completed as "Cross-Reference Consistency Audit"), but I've completed the Symbol Registry Integration Points Audit as requested in the user's context.
