# File Size Compliance Progress Report

**Date**: 2026-01-09
**Project**: rust-self-learning-memory
**Status**: IN PROGRESS - Ongoing file compliance work

---

## Executive Summary

This report tracks the progress of the 500 LOC file size compliance initiative per AGENTS.md guidelines. Several files still exceed the 500 LOC limit and require refactoring.

**Progress Summary**:
- **Files Previously Split**: 10 (completed in early January 2026)
- **Remaining Large Files**: 15+ files exceed 500 LOC
- **Total LOC Requiring Refactoring**: ~8,000+ LOC

## Refactoring Strategy

### Priority P0 (Critical - Blockers)

**memory-mcp files**:
1. `wasm_sandbox.rs` (683 LOC) → Split into runtime/compiler/modules
2. `javy_compiler.rs` (679 LOC) → Extract compiler phases
3. `unified_sandbox.rs` (533 LOC) → Split handler/implementation

**Strategy**: Extract by responsibility:
```
src/wasm_sandbox/
├── mod.rs           # Re-exports
├── runtime.rs       # Runtime initialization
├── instance.rs      # Instance management
├── channels.rs      # Channel creation
└── tests.rs         # Test suite
```

### Priority P1 (High - Next Sprint)

**memory-core embedding & pattern files**:
1. `embeddings/openai.rs` (672 LOC) → Extract request/response handling
2. `embeddings/config.rs` (660 LOC) → Extract validation helpers
3. `patterns/clustering.rs` (673 LOC) → Extract algorithm modules
4. `patterns/validation.rs` (623 LOC) → Extract validator types

**memory-storage files**:
5. `memory-storage-redb/src/cache.rs` (654 LOC) → Split cache ops
6. `memory-storage-turso/src/pool.rs` (589 LOC) → Extract pool management

### Priority P2 (Medium - Future Sprints)

**memory-core files**:
- `memory/learning.rs` (673 LOC)
- `pre_storage/quality.rs` (666 LOC)
- `learning/queue.rs` (662 LOC)
- `episode.rs` (649 LOC)
- `patterns/effectiveness.rs` (631 LOC)
- `episodic/capacity.rs` (613 LOC)

**memory-cli files**:
- `config/validator.rs` (636 LOC)
- `config/loader.rs` (623 LOC)
- `config/progressive.rs` (564 LOC)

### Priority P3 (Low - Cleanup)

**memory-core files** (just over 500 LOC):
- `sync.rs` (511 LOC)
- `reward/adaptive.rs` (510 LOC)

These can be addressed in a cleanup sprint.

## Validation Checklist

After each refactoring:

- [ ] All modules ≤ 500 LOC
- [ ] `cargo check --all` passes
- [ ] `cargo clippy --all -- -D warnings` passes
- [ ] `cargo fmt --check` passes
- [ ] Tests pass: `cargo test --all`
- [ ] Build succeeds: `cargo build --all`
- [ ] Public API preserved through re-exports

---

## Next Steps

### Immediate (This Week)

1. **Prioritize P0 files**: Start with `memory-mcp` sandbox files
   - `wasm_sandbox.rs` (683 LOC)
   - `javy_compiler.rs` (679 LOC)

2. **Follow proven pattern**:
   - Create `filename/` directory
   - Extract by responsibility (types, impl, tests)
   - Create `mod.rs` with re-exports
   - Update parent imports

### Short-term (Next 2 Weeks)

3. Complete P1 files:
   - Embedding-related files
   - Storage-related files

### Medium-term (Next Month)

4. Complete P2 files
5. Address P3 cleanup items
6. Achieve 100% compliance
