• #4044 4607916 @VaguelySerious - Honor WORKFLOW_NODE_HTTP on the queue client's transport, so a deployment whose bundled undici is unusable can still acknowledge queue messages instead of redelivering them until the invocation is killed.
• #4049 5f2fb36 @VaguelySerious - Give the queue client its own connection pool and a total per-request deadline, so a stalled queue acknowledgement fails fast instead of holding the invocation until the platform kills it.
