Expand description
Feedback recorder — captures (plan, estimate, actual) triples to a
SQLite sidecar so the residual correction model can learn from real
engine behavior. Inspired by Bao / AutoSteer.
The store is deliberately minimal: one process, one connection, one
table per concern. The schema is forward-compatible — new optional
columns can be added with ALTER TABLE migrations later.
