# Entrenar mdBook v0.1.0 Update - Quality & Anti-Hallucination

**Date**: 2025-11-21
**Status**: ✅ Complete
**Build Status**: ✅ Successful

## Overview

Updated Entrenar mdBook documentation to accurately reflect v0.1.0 **COMPLETE** status, following strict anti-hallucination quality standards from trueno/aprender projects.

## Anti-Hallucination Quality Standards Applied

### ✅ Only Documented Implemented Features

- **Verified all modules exist** in `src/` before documenting
- **No future features** presented as current (moved to "Future Roadmap")
- **Code examples** from actual working files in `examples/` and `src/`
- **Test counts** match actual `cargo test` output (258 not 130)

### ✅ Accurate Version Status

**Before (WRONG):**
```
Current Version: 0.1.0 (Phase 3: LoRA/QLoRA complete)
Tests: 130 passing
Future Roadmap:
  - Phase 5: Knowledge distillation and model merging
```

**After (CORRECT):**
```
Current Version: 0.1.0 ✅ COMPLETE
Tests: 258 passing (100% pass rate)
Completed v0.1.0 Features:
  ✅ Autograd, Optimizers, LoRA/QLoRA
  ✅ Model Merging (TIES, DARE, SLERP)
  ✅ Knowledge Distillation
  ✅ Training Loop, Model I/O, Declarative Config
```

### ✅ Module Structure Verification

**Verified actual modules** (not hallucinated):
```bash
$ ls src/
autograd/  ✅  (not "autograd_engine")
config/    ✅  (exists)
distill/   ✅  (exists)
io/        ✅  (exists)
lora/      ✅  (exists)
merge/     ✅  (exists)
optim/     ✅  (exists)
quant/     ✅  (NOT "quantization")
train/     ✅  (exists)
error.rs   ✅
lib.rs     ✅
```

**Note**: Quantization is `quant/` not `quantization/`, LLaMA is in `examples/llama2/` not `src/llama2/`

### ✅ Test Count Verification

```bash
$ cargo test 2>&1 | grep "test result:"
test result: ok. 258 passed; 0 failed; 0 ignored
```

**Updated all references**: 130 → 258 tests

**Breakdown** (from PROJECT_STATUS.md):
- 130 core library tests
- 18 gradient checking tests
- 35 architecture tests
- 16 I/O and configuration tests
- 13 property-based tests (13,000+ iterations)
- 15 chaos engineering tests
- 11 memory benchmark tests
- 10+ additional integration tests
- **Total: 258 tests**

## Comparison to trueno/aprender Standards

### trueno Book Quality Standards

- ✅ Clear separation: complete vs placeholder chapters
- ✅ Placeholder template: "Content to be added" + topics list
- ✅ Content migrated with full fidelity
- ✅ Real benchmark data only (no invented numbers)
- ✅ Build verification before commit

### aprender Anti-Hallucination Standards

- ✅ "Test EVERYTHING. Trust NOTHING. Verify ALWAYS."
- ✅ Every example is test-backed and verified
- ✅ No features documented before implementation
- ✅ Test counts match actual output
- ✅ Code examples compile and run

### Entrenar Implementation

✅ **All standards met**

## Usage Commands

### Build the Book

```bash
mdbook build book/
```

Output: `book/book/index.html`

### Serve Locally (with live reload)

```bash
mdbook serve book/
```

Then open: http://localhost:3000

### Verify Test Count

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

Output: `test result: ok. 258 passed; 0 failed; 0 ignored`

### Verify Modules Exist

```bash
ls src/{autograd,optim,lora,quant,merge,distill,train,io,config}
```

## Next Steps (Future Work)

### High Priority (v0.2.0)

1. **Fill remaining placeholders** (24 chapters):
   - TIES/DARE/SLERP algorithm details
   - Temperature-KL, multi-teacher, progressive distillation
   - Trainer API, save/load models
   - YAML config schema, optimizer/model builders

2. **Add real examples**:
   - Merge models example (from `examples/merge_models.rs`)
   - Distillation example (from `examples/distillation.rs`)
   - Training loop example (from `examples/training_loop.rs`)

3. **Update getting-started chapters**:
   - Quick start with new v0.1.0 features
   - First training loop with Trainer API
   - Model I/O workflow

### Medium Priority

4. **Performance benchmarks**:
   - Add real benchmark results (when available)
   - Memory savings data (LoRA vs QLoRA)
   - Training speed comparisons

5. **API reference**:
   - Extract from rustdoc comments
   - Add runnable examples

### Low Priority

6. **Advanced topics**:
   - Custom merging strategies
   - Advanced distillation techniques
   - Custom optimizer implementations
