Compression Domain

Scope

This domain covers the prompt and context compression pipeline that reduces request size before cache lookup, token budgeting, and routing. It documents the compression modes (lossless, standard, aggressive), the individual engines, preservation guarantees and fidelity gates, per-request controls, custom tool-output filters, and the statistics/preview APIs.
