Each node transition (Thought→Action→Observation) is a hash-chained, DSSE-signed receipt. A crash resumes from the last SqliteSaver checkpoint.
Generative-Agents retrieval:
score(m)=α_rec·γ^Δt + α_imp·imp(m) + α_rel·cos(q,m) (arXiv 2304.03442). Embeddings are LOCAL (hashing-trick, 0 CDN) HEURISTIC
Letta tiering — working (in-context) + archival (vector)
working cap = paging boundary; least-recently-used working items page out to archival.
Voyager skill library (arXiv 2305.16291): a tool-recipe is admitted only after a verified execution receipt. Indexed by local embedding.
