I upgraded Cypher’s model controls, moved it to GPT-5.6 Terra, and verified through the database that Terra was actually being used with medium reasoning and no fallback.

Then testing exposed a real problem.

Cypher knew my work rotation and the current date, but failed to apply them when I asked whether I was working that night.

I fixed that by adding a local schedule resolver that calculates my short and long weeks, handles overnight shifts, and gives Cypher the answer before the model responds.
