Old Training Evidence Needed a New Permit
BCIT checks whether a previously useful update still applies after later training changed the parent model.
Summary
BCIT checks whether a previously useful update still applies after later training changed the parent model.
The controller binds each observed update effect to its source model, data and training stage, vetoes hard conflicts and can demand a bounded current-state trial before reuse. In experiments adapting one 4B model across finance reasoning, text-to-SQL and function calling, the authors report fewer harmful authorizations and higher equal-budget final quality than their alternatives. The evidence covers one model and three adaptation contexts.
Why it matters
BCIT checks whether a previously useful update still applies after later training changed the parent model.
