| The activity package group: the non-consuming live-output observation plane under packages/activity/, for readers choosing or navigating the family. | package-group |
activity/ — streaming-output observation family
English | 中文
Summary
This family lets any number of independent observers watch a long-running producer's live output without touching the model-facing paths: an activity is an append-only bounded output stream plus live status, read at absolute byte offsets that survive eviction. activity defines the registry contract and vocabulary; activity-local implements the in-memory ring-buffer registry. The plane is optional and invisible to the model — a composition without it loses only live observation.
