# PyPI Release Preparation Report - 2025-12-02

**Status:** Test-PyPI Release Complete
**Version:** 2.4.0rc1
**Date:** 2025-12-02

---

## Executive Summary

Package `llm-security-firewall` version 2.4.0rc1 has been successfully uploaded to Test-PyPI. Version synchronization issues between CHANGELOG (ending at 2.3.4) and package metadata (5.0.0rc*) have been resolved. All package metadata, documentation, and dependencies are synchronized.

---

## Version Synchronization

### Problem Identified

- **CHANGELOG.md** ended at version 2.3.4 (2025-11-29)
- **Package metadata** contained versions 5.0.0rc1, 5.0.0rc2, 5.0.0rc3
- **README.md** showed version 5.0.0rc1
- No documentation existed for the jump from 2.3.4 to 5.0.0

### Resolution

Version set to **2.4.0rc1** (semantic versioning: minor version increment for feature additions).

**Rationale:**
- Hexagonal Architecture refactoring is a feature addition, not a breaking change
- No breaking changes identified between 2.3.4 and current state
- Maintains consistency with existing version history

### Files Updated

1. `CHANGELOG.md`: Added entry for 2.4.0rc1 documenting:
   - Hexagonal Architecture refactoring (2025-12-01)
   - Developer Adoption API (`guard.py`)
   - LangChain Integration (pre-structured)
   - PyPI Package Preparation

2. `pyproject.toml`: Version set to 2.4.0rc1

3. `src/llm_firewall/__init__.py`: `__version__` set to "2.4.0rc1"

4. `README.md`: Version updated to 2.4.0rc1

## Package Metadata Corrections

### Email Address

**Issue:** Package metadata and README contained `info@hakgal.org`
**Resolution:** Updated to `sookoothaii@proton.me`

**Files Modified:**
- `pyproject.toml`: `authors` and `maintainers` fields
- `README.md`: Author section

**Note:** PyPI displays email from account settings, not package metadata. Account email must be updated separately in PyPI account settings.

### Package Description

**Previous:** "Bidirectional Security Framework for Human/LLM Interfaces - 9 Core + 27 Hardening Layers, 832/853 Tests (97.5% PASS), MyPy Clean, CI GREEN"

**Updated:** "Cognitive Security Middleware - The 'Electronic Stability Program' (ESP) for Large Language Models. Bidirectional containment system with defense-in-depth architecture, stateful tracking, and mathematical safety constraints."

**Rationale:** Description now matches README.md content and avoids specific test count claims that may become outdated.

## Package Contents

### Lexicons Inclusion

**Issue:** Initial package builds (5.0.0rc1, 5.0.0rc2) were missing required lexicon files, causing runtime errors.

**Resolution:**
- Updated `MANIFEST.in` to include:
  - `recursive-include src/llm_firewall/lexicons *.json`
  - `recursive-include src/llm_firewall/lexicons *.py`
  - `recursive-include src/llm_firewall/lexicons_gpt5 *.json`

**Verification:**
- Package contains 11 lexicon files (lexicons/ + lexicons_gpt5/)
- `intents.json` present in lexicons_gpt5/
- Runtime import tests pass

### Package Structure

**Total Files:** 284 files in wheel distribution
**Size:** ~528 KB (wheel), ~863 KB (source distribution)

**Included Components:**
- Source code: `src/llm_firewall/`, `src/hak_gal/`, `src/layer15/`
- Lexicons: `src/llm_firewall/lexicons/`, `src/llm_firewall/lexicons_gpt5/`
- Configuration: `config/`, `policies/`
- Examples: `examples/`
- Documentation: `docs/`, `README.md`, `CHANGELOG.md`, `QUICKSTART.md`

## Test-PyPI Upload

### Upload Process

1. **Build:** `python -m build --wheel --sdist`
2. **Validation:** `twine check dist/*` (PASSED)
3. **Upload:** `twine upload --repository-url https://test.pypi.org/legacy/ dist/*`

### Uploaded Files

- `llm_security_firewall-2.4.0rc1-py3-none-any.whl` (527.9 KB)
- `llm_security_firewall-2.4.0rc1.tar.gz` (863.1 KB)

### Version Management

**Previous Versions on Test-PyPI:**
- 5.0.0rc1 (yanked)
- 5.0.0rc2 (yanked)
- 5.0.0rc3 (yanked)

**Action Taken:** All 5.0.0rc* versions yanked via Test-PyPI web interface to prevent version confusion.

**Current Active Version:** 2.4.0rc1

---

## Technical Validation

### Package Validation

```bash
twine check dist_2_4_0_rc1_final/*
# Result: PASSED for both wheel and source distribution
```

### Metadata Verification

- **Author-Email:** `Joerg Bollwahn <sookoothaii@proton.me>` ✓
- **Maintainer-Email:** `Joerg Bollwahn <sookoothaii@proton.me>` ✓
- **Version:** 2.4.0rc1 ✓
- **Description:** Matches README.md ✓

### Runtime Verification

**Not yet tested.** Installation from Test-PyPI requires:
1. Test-PyPI indexing (5-10 minutes after upload)
2. Fresh virtual environment
3. Installation test: `pip install --index-url https://test.pypi.org/simple/ llm-security-firewall==2.4.0rc1`
4. Import test: `from llm_firewall import guard`
5. Functional test: `guard.check_input("test")`

---

## Known Limitations

1. **Test-PyPI Indexing Delay:** New uploads require 5-10 minutes for indexing. Installation may fail immediately after upload.

2. **Account Email Display:** PyPI displays email from account settings, not package metadata. Account email update required separately.

3. **Dependencies:** Package declares extensive dependencies (torch, transformers, onnx, etc.). Installation may fail if:
   - System lacks required build tools
   - Dependency versions conflict with existing packages
   - Platform-specific wheels unavailable

4. **Lexicons Runtime Dependency:** Package requires lexicon files at runtime. Missing lexicons cause `FileNotFoundError` during import.

---

## Next Steps

### Immediate (Pre-Production)

1. **Installation Test:** Verify package installs and imports correctly from Test-PyPI after indexing completes.

2. **Functional Test:** Execute `examples/quickstart.py` with installed package.

3. **Account Email Update:** Update email in Test-PyPI account settings to match package metadata.

### Production Release (Blocked Until)

1. All Test-PyPI validation tests pass
2. Account email confirmed correct on Test-PyPI
3. No critical issues identified in Test-PyPI installation
4. Production PyPI API token obtained
