## Scope

Capsule compacts repetitive terminal, file, project, web, memory, and context output while preserving local exact recovery. It passes through failures, unsafe or ambiguous requests, explicit full-output requests, and token-negative candidates.

## Measurement caveat

Published percentages are workload-specific model-visible observations. They do not claim control over hidden provider reasoning, provider caching, billing, or subscription quotas.
