# Section 07 Code Review Interview

## Triage Summary

| # | Severity | Issue | Decision |
|---|----------|-------|----------|
| 1 | HIGH | Focus node lost after include filter | **Auto-fix** — Search unfiltered list before include filter |
| 2 | MEDIUM | No detail parameter validation | **Let go** — Consistent with project_summary pattern |
| 3 | MEDIUM | total_nodes misleading with filters | **Let go** — total_nodes represents scene total, len(nodes) is self-evident |
| 4 | MEDIUM | Distance matrix O(n^2) no cap | **Auto-fix** — Cap at 50 pairs |
| 5 | LOW | Silent no-op when focus not found | **Auto-fix** — Add warning field |
| 6 | LOW | Hardcoded 0.5 threshold | **Let go** — Matches plan spec exactly |
| 7 | LOW | File path discrepancy | **Let go** — Already correct (package matches codebase) |
| 8 | INFO | Missing edge case tests | **Let go** — Core behavior well tested |
| 9 | INFO | lifespan_context correct | **No action** |

## Fixes Applied

### Fix 1: Focus node search before include filter (HIGH)
- Moved focus node search to before include filter application
- Focus node found in unfiltered world_nodes list
- After include filter + radius filter, focus node re-inserted if filtered out

### Fix 2: Warning when focus node not found (LOW)
- Added `"warning"` field to result when focus name doesn't match any node

### Fix 3: Distance matrix cap (MEDIUM)
- Added `_MAX_DISTANCE_PAIRS = 50` constant
- Early return when cap reached

## Deferred Items

- **Detail validation**: Other tools (project_summary, file_context) don't validate their parameters either. Consistent to leave this as-is.
- **total_nodes meaning**: The field represents the full scene node count which is useful context regardless of filtering.
- **0.5 threshold**: Matches spec exactly, no reason to deviate.
- **Edge case tests**: The 12 tests cover all specified behaviors. Additional edge cases are nice-to-have but not blocking.
