Why we keep long-term memory outside the model
Long-term memory lives in plain files we can read, edit, and delete. It is not the most elegant choice. It is the one whose mistakes we can actually fix.

The 2026 MCP spec removes the protocol-level session. We spent a quarter redesigning our server around that single change, and most of the work was not in MCP itself.

Quality drops well before the context window is full. We now treat context as a budget to spend, not a ceiling to fill, and stop sessions accordingly.
