Memory
What agents remember, who may read it, and how it stays current.

Agent memory that remembers the current answer
Building a multi-tenant memory service where identity bounds access, later facts supersede earlier ones, and tests grade the final answer rather than retrieval.

Making an agent’s memory useful without slowing its next reply
Capture, evidence, retrieval, projection and delivery can each fail alone. A small replay found a fact lost before search could see it, and 92 live calls carried no receipt that any memory had arrived.

Compacting agent conversations without losing the source
How a compaction ledger keeps instructions verbatim, ties each fact to the journal entries behind it, and recovers original evidence within a fixed scope.

Evidence should belong to the run that used it
How per-run source rows, revision checks and publication-time binding keep a research report tied to the evidence it used, and what that doesn't prove.

Forgetting a memory must survive the retry that created it
How a delayed create can bring a deleted memory back, and what stops it: durable operation receipts, a tombstone that keeps only the ID, supersession edges moved before a duplicate is forgotten, and recall whose staleness has a stated bound.

Reducing allocation churn in an agent platform
Why an agent gateway with broad retained state allocated gigabytes a minute, how repeated sizing and serialization drove it, and what bounded buffers and encode-once paths do and don't fix.
