A special thinking-block check is wired up but always answers no

Not switched on
Useful1 Signal4
Thinking

Handling for a special kind of thinking block exists, but the check always answers no here.

Detection of a "special" thinking block needs a registered matcher that this build does not have, so the branches never run.

What

New helpers ask whether an assistant message begins with a "special" thinking block, requiring both a thinking string and a signature string plus a registered matcher. Where the answer is yes, the message stops counting as thinking-only for context assembly, the streaming thinking panel is cleared rather than updated, and the message is treated as a real assistant turn.

Details
  • The matcher variable starts as null and nothing in the build assigns it, so the check always returns false and none of those branches run.

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