What

The two thresholds that decide when a session hands off its work fell from 25 and 35 to 10 and 15 for claude-opus-4-8. Sonnet 5 is unchanged at 25 and 35. These are the built-in defaults for the handoff decision and can be overridden by server-side config.

Evidence

"claude-opus-4-8": { t1: 10, t2: 15 }

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
