What

A response block missing fields it should have no longer throws. A text block whose text is not a string is dropped, and a thinking block missing its thinking text or signature gets empty strings substituted so the conversation continues.

Details
  • Each repair reports the block type, whether it was dropped or healed, which fields were missing, and the request and message ids.
  • Unconditional: there is no flag guarding this, it always runs in the block normalizer.
Evidence

tengu_content_block_healed

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