Compression Fidelity Validator
Software componentMemoryCognition & Memoryarc:CompressionFidelityValidator
A verification component that checks compressed summaries or extractions against their source through entailment, coverage and consistency checks before they replace original content in working memory.
Responsibility. Validates that compressed context is faithful to its source.
Also known as: Compression with validation, Compression quality monitoring, Validated compression

evaluates assurance
Design guidance
- SHOULD verify each generated summary before it replaces source content in working memory.
- MUST fall back to regeneration, less aggressive compression, or the original content when validation fails.
Quantitative guidance
As stated by the sources; verify before use.
- Validation adds ~20-40% to compression latency (Ch5.9).
