# Entrenar Book Quality & Anti-Hallucination Checklist

## Quality Standards (following trueno/aprender pattern)

### ✅ Anti-Hallucination Requirements

1. **Only Document Implemented Features**
   - ❌ Do NOT mention features planned but not implemented
   - ❌ Do NOT use "coming soon" or "future work" for v0.1.0 chapters
   - ✅ ONLY describe code that exists in `src/`
   - ✅ Verify every code example compiles and runs

2. **Accurate Test Counts**
   - Current: 258 tests passing (NOT 130)
   - Must match output of `cargo test`
   - Update all references to test counts

3. **Precise Version Status**
   - v0.1.0 is COMPLETE (not "in progress")
   - All phases DONE: Autograd, Optimizers, LoRA/QLoRA, Merging, Distillation, Training, I/O, Config
   - Do NOT say "Phase 5: Knowledge distillation" is future - IT'S DONE

4. **Real Benchmark Data Only**
   - Use actual data from `tests/` or examples
   - No invented performance numbers
   - Reference specific test files

5. **Code Examples from Actual Files**
   - Examples must be from `examples/` or `src/`
   - Include file references: `(from examples/model_io.rs)`
   - Test that examples compile

### ✅ Content Verification

- [ ] Introduction updated with v0.1.0 complete feature set
- [ ] Test counts: 258 (not 130)
- [ ] Features listed match CHANGELOG.md
- [ ] No future roadmap items in main content (move to appendix)
- [ ] Code examples compile
- [ ] Benchmark data is real (from actual test output)
- [ ] New chapters for: Model Merging, Distillation, Training Loop, Model I/O, Declarative Config

### ✅ Completed v0.1.0 Features (Must Be Documented)

1. **Autograd Engine** ✅ (exists in src/autograd/)
2. **Optimizers** ✅ (SGD, Adam, AdamW in src/optim/)
3. **LoRA/QLoRA** ✅ (src/lora/, src/quantization/)
4. **Model Merging** ✅ (TIES, DARE, SLERP in src/merge/)
5. **Knowledge Distillation** ✅ (src/distill/)
6. **Training Loop** ✅ (src/train/trainer.rs)
7. **Model I/O** ✅ (src/io/)
8. **Declarative Config** ✅ (src/config/train.rs)
9. **LLaMA 2 Transformer** ✅ (src/llama2/)

### ✅ Test Coverage Breakdown (Must Be Accurate)

From PROJECT_STATUS.md:
- 130 core library tests
- 13 property-based tests (1,300 cases)
- 10 mutation-resistant tests
- 15 chaos engineering tests
- 18 gradient checking tests
- 11 memory benchmark tests
- 35 architecture tests
- 16 I/O and configuration tests
- 10 additional integration tests
**Total: 258 tests**

### ❌ Do NOT Hallucinate

- Performance numbers without test references
- Features not in v0.1.0 (e.g., distributed training, GPU support)
- Code that doesn't exist
- Test counts that don't match `cargo test` output
- Future phases as if they're current

### ✅ Placeholder Chapters

If content is incomplete:
- Use standard placeholder format
- State "Content to be added"
- List topics to cover
- Reference to check back later

## Verification Commands

```bash
# Verify test count
cargo test 2>&1 | grep "test result:"

# Verify features exist
ls src/{autograd,optim,lora,quantization,merge,distill,train,io,config,llama2}

# Verify examples compile
cargo build --examples

# Build book
mdbook build book/
```

## Sign-Off

- [ ] All features verified to exist in codebase
- [ ] All test counts match `cargo test` output
- [ ] All code examples compile
- [ ] No hallucinated features or benchmarks
- [ ] Version status accurate (v0.1.0 COMPLETE)
