Research-driven resolution of OQ-01, OQ-02, OQ-05, OQ-06:
- OQ-01: Remove ONNX Runtime from scope entirely — doesn't support
activation extraction natively (optimum #972 closed as not planned),
bloated model exports; burn/cublas via safetensors is a better future path
- OQ-02: Codebook compresses ~65% (1,245 → 500-600 lines); add Package
Structure and Extraction from PoC sections to codebook.md based on PoC
analysis of metaspline firewall_codebook.py
- OQ-05: Standalone API + thin adapter pattern (ADR-011); Phase 1 ships
Firewall.screen() only, Phase 2 adds <100-line adapter packages for
LlamaFirewall, OpenAI Agents SDK, NeMo Guardrails
- OQ-06: TOML for file-based config — standard modern Python, two-way door
Also: research OQ-03 rolling windows from taskgraph-semantic reference code,
remove onnxruntime/optimum from dependencies, move streaming screening to
Phase 2, add burn/cublas as Phase 3 alternative backend.
