Nightly Memory Curation: Faster, Focused, Complete

Every night, your assistant reviews what it has learned about you — merging duplicates, resolving contradictions, promoting the notes that matter and retiring the ones that don't. That process just got noticeably quicker. We removed a piece of setup work that ran before every single step of the nightly pass, connecting and disconnecting tools the curation work could never actually use. The result is roughly 150ms saved per step and hundreds of unnecessary connections avoided each night, which added up to a sevenfold speedup on the busiest internal path during real-world testing.

Speed only helps if the work finishes. In early overnight runs, curation was hitting an internal ceiling on how much it could do in a single pass — and it was hitting it mid-merge, which meant memory updates were sometimes refused or left half-written. Measuring an unconstrained pass showed the real workload was about twice the size of the allowance it had been given. We've raised the ceiling to match the actual job and doubled the room the pass has to write its results, so a night's curation now runs to a clean finish instead of stopping partway through. Overnight passes now complete in under four minutes, where the previous approach frequently timed out.

Behind the scenes, we also changed how the curation procedure itself is delivered. Instead of restating the full set of instructions at the start of every task, the assistant now pulls the procedure in on demand, from a single shared definition. Less overhead per run, one source of truth for how curation works, and no change to the outcome — just a cleaner foundation for the improvements we want to make next.

What all of this adds up to is quieter reliability: a memory that stays accurate and current without you thinking about it, and headroom for a much richer nightly pass as your history grows.
