What

The factory that builds headless and SDK sessions takes a new sdkResultVerdict option defaulting to false, which one caller sets to true. Separately, the SDK tool list now passes through a step that appends PollTool when the permission context includes it and it is not already listed.

Evidence

sdkResultVerdict

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