Notes
Three notes, from the repository
These are engineering notes. The figures in them are the ones already on the benchmarks page, rendered from the same source. Nothing new was measured for this site.
On this page
- A memory without a source is hearsay
Agent memory products often store a sentence and a vector. The sentence might be a tool result, a file the agent read, or something a user said once. Those are not the same kind of evidence, and a retrieval score does not record which one you have.
- The headline that counted turns the engine never retrieved
LoCoMo evidence recall asks whether the right conversation turn came back. An earlier headline for that measurement was withdrawn. The figures this site still prints are below, from the same source as the benchmarks page, with the same conditions.
- Kill the writer. Open the brain. See if it verifies.
Crash recovery in this repository is a Rust test, not a slogan. It was read for this note and not re-run. What was re-run is the Python contract: checkpoint(), then a new process.
A feed
The three notes are also an Atom feed . Dates are the day the note was written, 30 September 2026, not a backdated launch.
