 remains HTTP transport and is not a workflow payload codec.

 ### Fixed
-- Cold replay now treats an intervening durable step as the authoritative
-  boundary for later signals and updates, even when they retain an older
-  condition sequence. Post-condition activities can therefore complete before
-  those receivers advance the workflow without rebinding them to a closed wait.
 - The README and PyPI project description now require Server worker protocol
   `>=1.19,<2.0`. Package and API-reference release validation derive that
   interval from the shipped SDK protocol and reject semantic guidance drift.
