# Section 05: Project Summary Architectural Enrichment

## Status: COMPLETE

## Files Modified
- `src/godotiq/tools/memory/__init__.py` — Added signal_health, health, and autoload enrichment to `_build_full()`
- `tests/test_tools/test_project_summary.py` — Added 12 new tests (42 total)

## What Was Built

### Fix 5a: Autoload Enrichment (detail="full" only)
Added to each autoload entry in `autoload_analysis`:
- `signals_defined`: int count of signal definitions
- `signals_emitted`: int count of signal emissions
- `referenced_by_count`: int count of scripts referencing this autoload

### Fix 5b: Signal Health Summary (detail="full" only)
New top-level `signal_health` dict:
- `total_defined`: total signal definitions across all scripts
- `total_emissions`: total signal emission sites across all scripts
- `total_connections`: total code-based signal connections (normalized by bare name)
- `orphan_count`: signals emitted but never connected-to
- `top_signals`: top 5 most-connected signals with `name` and `listeners`

### Fix 5c: Project Health (detail="full" only)
New top-level `health` dict:
- `orphan_signals`: same as signal_health.orphan_count
- `scripts_without_class_name`: non-autoload scripts missing class_name
- `note`: human-readable summary string

## Code Review Fixes Applied
1. **Normalized connection keys** — `get_all_signal_connections()` returns qualified keys (`EconomyManager.cash_changed`); normalized with `rsplit(".", 1)[-1]` to match emission keys
2. **Added `signals_emitted` field** — missing from initial implementation per spec
3. **Added orphan count correctness test** — verifies against known fixture data

## Tests Added (12 new)
- `TestProjectSummaryFullAutoloadEnrichment` (4 tests): signals_defined, signals_emitted, referenced_by_count, signals_defined matches list
- `TestProjectSummaryFullSignalHealth` (4 tests): structure, top_signals format, orphan count correctness, non-negative totals
- `TestProjectSummaryFullHealth` (2 tests): structure, non-negative values
- `TestProjectSummaryNoExtrasAtLowerDetail` (2 tests): normal and brief exclude new fields
