# Proposal: Consolidate Python Orphan Tables - Delete 141 Unused Tables

## Executive Summary

**Hypothesis**: ~60 Python tables are "shit that isn't even wired up"
**Verified Reality**: **141 out of 149 Python tables are NEVER queried** by any analysis code

This proposal deletes 141 orphan tables, keeping only 8 that are actually used. This is a DELETION proposal, not a reorganization.

**Risk Level: MEDIUM** - Tables have no consumers, deletion is safe but irreversible

---

## Why

### The Problem (Verified 2025-11-25)

```
PYTHON TABLES: 149 total
  - Tables ACTUALLY QUERIED: 8 (5.4%)
  - ORPHAN tables (never queried): 141 (94.6%)
  - Empty tables (0 rows): 10

COMPARISON:
  Node/JS: 5 tables, 5 used = 100% utilization
  Python: 149 tables, 8 used = 5.4% utilization
```

### Root Cause

1. **Original design for different tool**: Tables were built for another project and imported into TheAuditor hoping for "win in 2 places"
2. **"Extract everything" mentality**: Python extractors exhaustively capture AST patterns without corresponding analysis consumers
3. **No utilization gate**: Tables were added without requiring a consuming rule/command to justify them
4. **Cache hides the bloat**: `SchemaMemoryCache` loads ALL 250 tables into memory, masking that 141 are never read

### Impact of Doing Nothing

1. **AI Cognitive Load**: Any AI navigating 149 Python tables goes "what the fuck" and gives up
2. **Memory Waste**: SchemaMemoryCache loads 141 unused tables every pipeline run
3. **Maintenance Burden**: 141 extractors, storage handlers, and schema definitions to maintain
4. **Misleading Architecture**: Makes TheAuditor look over-engineered
5. **Conflicts with refactor-python-schema-split**: That proposal moves tables around; this one deletes them first

---

## Verification Evidence (Due Diligence)

### Method

1. Ran `grep -r "SELECT.*FROM.*python_"` across entire codebase
2. Excluded schema/storage/database definition files (those define tables, not query them)
3. Traced cache usage in `taint/discovery.py`
4. Verified row counts in live `.pf/repo_index.db`

### Tables That ARE Queried (8 tables - KEEP)

| Table | Queried By | Purpose |
|-------|------------|---------|
| `python_decorators` | `interceptors.py`, `deadcode_graph.py`, `query.py` | Decorator->function flow |
| `python_django_middleware` | `interceptors.py` | Django middleware->view flow |
| `python_django_views` | `interceptors.py` | Django view endpoints |

| `python_orm_models` | `overfetch.py`, `discovery.py` | Model-level analysis |

| `python_routes` | `boundary_analyzer.py`, `deadcode_graph.py`, `query.py` | Flask/FastAPI routes |

## Impact Assessment

### Breaking Changes

| Impact | Description | Affected Code |
|--------|-------------|---------------|
| NONE | Tables have NO consumers | N/A |
| NONE | No rules query deleted tables | Rules continue working |
| NONE | No commands query deleted tables | Commands continue working |
| NONE | Taint analysis doesn't use deleted tables | Taint continues working |

### Positive Impact

| Benefit | Metric |
|---------|--------|
| Memory reduction | SchemaMemoryCache loads 109 tables instead of 250 (~56% fewer) |
| Schema complexity | 8 Python tables instead of 149 (~95% simpler) |
| Cognitive load | AI can navigate Python schema easily |
| Code maintenance | 19 fewer extractor files to maintain |
| Indexing speed | Fewer tables = faster indexing |

### What Still Works After Deletion

1. **Taint analysis** - Uses `python_orm_models`, `python_validators` (KEPT)
2. **Interceptor strategy** - Uses `python_decorators`, `python_django_*` (KEPT)
3. **Boundary analyzer** - Uses `python_routes` (KEPT)
4. **Deadcode graph** - Uses `python_routes`, `python_decorators` (KEPT)
5. **Blueprint command** - Uses `python_package_configs` (KEPT)
6. **GraphQL overfetch** - Uses `python_orm_models`, `python_orm_fields` (KEPT)

## Relationship to Other Proposals

### `refactor-python-schema-split`

That proposal moves 149 tables into domain-specific files. THIS proposal should execute FIRST:
1. Delete 141 orphan tables (this proposal)
2. Then decide if remaining 8 tables need reorganization (simpler decision)

**Recommendation**: Archive `refactor-python-schema-split` or reduce scope to only 8 tables.

---

## Rollback Plan

```bash
git revert <commit_hash>
rm -f .pf/repo_index.db
aud full --index
```

**Note**: Deleted data cannot be recovered without re-indexing. But since no code queries these tables, no functionality is lost.

---

## Verification Criteria

- [ ] `len(TABLES) == 109` (was 250, -141)
- [ ] `len(PYTHON_TABLES) == 8` (was 149, -141)
- [ ] `aud full --offline` succeeds
- [ ] `pytest tests/test_code_snippets.py tests/test_explain_command.py -v --tb=short` passes
- [ ] Taint analysis works (uses remaining tables)
- [ ] Interceptor strategy works (uses remaining tables)
- [ ] Memory usage reduced in pipeline

---

## Approval Gate

**DO NOT PROCEED** until:
1. Architect reviews deletion list
2. Lead Auditor validates no hidden consumers
3. Both approve irreversible deletion

This is a **medium-risk deletion** - safe because no consumers, but irreversible.

---

## Questions for Review

1. **Security tables**: `python_sql_injection`, `python_command_injection`, etc. are extracted but never used. Delete them or wire up rules?
   - **Recommendation**: Delete. If rules are needed later, re-add with consumers.

2. **Testing tables**: `python_pytest_*` are extracted but never queried. Keep for future use?
   - **Recommendation**: Delete. Follow "no consumers = no table" principle.

3. **Causal learning tables**: Built for ML pipeline that doesn't exist. Delete?
   - **Recommendation**: Delete. Can re-add when ML pipeline is implemented.
