# SESSION 1 — Scaffold — COMPLETE ✅

## What Was Created

### Directory Structure
- **src/ai_qa/** — Main package with 11 submodules
- **tests/unit/** — 27 unit test files (core, checks, integrations)
- **tests/integration/** — 3 integration test files
- **tests/fixtures/** — Fixture directory
- **.github/workflows/** — CI/CD automation
- **docs/** — Documentation directory (empty, for Session 13)
- **examples/** — Example scripts directory (empty, for Session 14)

### Source Modules (52 files)

#### Core (5 modules)
- `context.py` — Data container for validation inputs
- `result.py` — CheckResult and ValidationResult classes
- `check.py` — BaseCheck abstract class
- `config.py` — Global configuration singleton
- `runner.py` — Concurrent check executor

#### Checks (18 modules)
**LLM-Powered**: hallucination, factuality, relevance, toxicity, consistency
**Deterministic**: schema, regex, json_format, length
**Agent/RAG**: tool_use, trajectory, groundedness
**Safety**: bias, pii, prompt_injection
**Conversation**: context_retention, contradiction
**User-Defined**: custom

#### Providers (4 modules)
- `base.py` — BaseProvider abstract class
- `anthropic.py` — Claude provider
- `openai.py` — OpenAI provider
- `local.py` — Local/Ollama provider

#### Other Modules
- **datasets/**: loader.py, generator.py
- **evaluation/**: suite.py, snapshot.py, experiment.py
- **adversarial/**: red_team.py, attacks.py
- **monitor/**: monitor.py
- **integrations/**: pytest_plugin.py, reporters.py
- **cache/**: cache.py
- **cli/**: main.py
- **exceptions.py**, **_version.py**, **py.typed**

### Configuration Files
- **pyproject.toml** — Complete project metadata, dependencies, and build config
- **CLAUDE.md** — Development guidelines and instructions
- **.gitignore** — Comprehensive ignore patterns
- **tests/conftest.py** — Shared pytest fixtures

### CI/CD Workflows
- **.github/workflows/ci.yaml** — Linting, type checking, unit tests on Python 3.10-3.13
- **.github/workflows/publish.yaml** — PyPI publishing on version tags

## Validation Results

✅ **Directory Structure**: 18 directories created
✅ **Source Files**: 52 Python files (all compile without errors)
✅ **Test Files**: 27 test files scaffolded
✅ **Configuration**: pyproject.toml, CLAUDE.md, .gitignore present
✅ **Workflows**: CI and publish workflows configured

## What's Ready for Session 2

All empty modules with docstrings are in place. The next session will implement:
1. **Context** dataclass with Pydantic validation
2. **CheckResult** and **ValidationResult** classes
3. **BaseCheck** abstract base class
4. **Config** singleton
5. Custom **AIQAError** exception hierarchy
6. All unit tests for core primitives

## Key Design Points Established
- Import name: `ai_qa`
- Python 3.10+ support
- Minimal core dependencies (pydantic, httpx, jsonschema, rich, click, pyyaml)
- Optional LLM SDK extras (anthropic, openai)
- Strict mypy type checking enabled
- 100+ character line length configured
- pytest entry points for plugin auto-discovery
- CLI entry point configured as `ai-qa` command

## Next Steps
→ **Session 2**: Implement Core Primitives (Context, CheckResult, ValidationResult, BaseCheck, Config, Exceptions)
