# Changelog

All notable changes to OBLITERATUS are documented here.
Format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).

## [0.1.2] - 2026-03-03

### Fixed
- Fixed `spaces.GPU` `AttributeError` crash on HuggingFace Spaces — fallback now catches
  both `ImportError` and `AttributeError` so the Space gracefully degrades to CPU mode
  when ZeroGPU is unavailable
- Added missing `hardware: zero-a10g` to HF Space metadata (`hf-spaces/README.md`) —
  required for the `spaces` package to expose the `@spaces.GPU` decorator

### Improved
- Added mypy type checking to CI pipeline (`continue-on-error` while baseline is established)
- Added `mypy` to dev dependencies
- Version bump to 0.1.2 across `pyproject.toml` and `__init__.py`

## [0.1.1] - 2026-03-01

### Fixed
- Fixed all broken imports (missing function exports in telemetry, evaluation, analysis modules)
- Resolved all ruff lint errors across the codebase
- Corrected GitHub org name in all documentation and configuration files
- Updated test count in README to match actual collectible tests
- Softened overclaim language in documentation and paper

### Improved
- Added test coverage reporting (`pytest-cov`) to CI pipeline
- Added `USER` directive and `HEALTHCHECK` to Dockerfile for security best practices
- Synchronized `requirements.txt` with `pyproject.toml` dependencies
- Removed duplicate `THEORY_JOURNAL.md` from docs
- Hyperlinked all arXiv references in README
- Added Pliny the Prompter attribution

## [0.1.0] - 2026-02-27

### Added
- **15 analysis modules** for mechanistic interpretability of refusal mechanisms
- **Analysis-informed pipeline** (`informed` method) — closed-loop feedback from analysis to abliteration
- **Ouroboros compensation** — automatic detection and compensation for self-repair after excision
- **Steering vectors** — reversible inference-time guardrail removal (Turner et al. / Rimsky et al.)
- **Community contribution system** — `--contribute` flag and `obliteratus aggregate` for crowdsourced results
- **47 curated model presets** across 5 compute tiers (CPU to multi-GPU)
- **10 study presets** for reproducible ablation experiments
- **4 ablation strategies**: layer removal, head pruning, FFN ablation, embedding ablation
- **4 abliteration methods**: basic, advanced, aggressive, informed
- **Web dashboard** (`docs/index.html`) with config builder, model browser, results visualizer
- **Gradio playground** (`app.py`) — one-click obliteration + chat in the browser
- **Colab notebook** for zero-install usage
- **Evaluation suite**: refusal rate, perplexity, coherence, KL divergence, CKA, effective rank
- **lm-eval-harness integration** for standardized benchmarking
- **Reproducibility framework** with deterministic seeds and full metadata logging
- **Telemetry** (opt-in only, anonymized, allowlisted fields)
- **823 tests** across 28 test files (incl. CLI dispatch, shared fixtures)
- **Research paper** (`paper/main.tex`) with geometric theory of refusal removal
- Dual license: AGPL-3.0 + commercial

### Security
- `trust_remote_code` defaults to `False` — users must explicitly opt in
- All temporary paths use `tempfile.gettempdir()` for cross-platform safety
- Telemetry never collects model names, prompt content, file paths, or PII
