01 / verified archive
Every memory has a way home.
Hearth keeps the approved source object intact and attaches every derived passage to exact offsets, hashes, and ingestion receipts.
02 / temporal truth
Three clocks. One honest record.
When something happened, when it was observed, and when it entered Hearth remain separate—so an old statement never masquerades as a current belief.
03 / context compiler
Give the model enough—not everything.
Each request becomes a budgeted context package with governing memory, immediate work, exact evidence, and reserved room for counterevidence.
04 / memory review
The model may notice. You decide.
Potential durable memories enter a review queue with citations, confidence, sensitivity, and contradiction checks. They remain inactive until the owner acts.
05 / tool boundary
Invite the tool. Not the whole archive.
Local models and coding agents receive explicit capabilities. Search and exact reading can be granted while ingestion, deletion, networking, and approval stay outside.
06 / ordinary exit
Change the intelligence. Keep what is yours.
Sources, decisions, receipts, and context manifests live behind a stable local boundary. Replacing a model never requires rebuilding your continuity.
