Design memos, Reflex deep dives, and architecture explainers from the team building Contexta. Sharp, technical, occasionally opinionated.
Vector similarity finds what looks the same; provenance proves what is true. The hybrid recall score in Contexta blends three signals — semantic, structural, provenance — and tunes per namespace.
A walkthrough of the Reflex DSL: how CX expressions decompose into Motifs, how Loci hold history, and how one entity covers both graph-shape completion and scalar drift.
Agents do not fail at retrieval — they fail at context. The harness is what holds an agent's reasoning together when memory, reactivity, and provenance work as one substrate.
One pragmatic post per fortnight on reactive memory, provenance, and what we learn shipping into production agents.
