The Brain
How Agentis agents form, recall, and ground memory over time: the formation pipeline, hybrid recall with citations, knowledge bases, and living skills.

All Brain memory lives in one table, discriminated by plane, scope, and type — why a single substrate beats a dozen disconnected memory stores.
Writing memory is reconciliation, not append: deterministic extraction, a two-phase Formation Judge (ADD/UPDATE/NOOP), PACER routing, and Feynman repair.
Hybrid TF-IDF plus embedding recall with freshness decay, trust weighting, MMR diversification, and citation-or-abstain grounded answers.
An evidence ledger, versioned sources, claims with an approval workflow, conflict resolution, and per-agent grants — the Brain's organizational-intelligence engine.
Ingest, chunk, embed, auto-link, and enrich uploaded documents — PDFs, docx, and text — into searchable knowledge atoms.
Body on disk, metabolism in the Brain: a real SKILL.md a harness loads natively, paired with a confidence-tracked skill atom that graduates by reuse.
Private, per-user notes and a personal knowledge graph, distinct from the shared workspace Brain.
The cross-scope brain graph that unifies chat-as-dispatch with the rest of workspace memory.
The background pass that ages, compresses, and reembeds memory over time, plus the health checks that keep recall honest.
The scoring mechanics behind recall: freshness decay, trust weighting, reranking, and MMR diversification, explained with real inputs.
