Agent Middleware fixes bug mislabeling completed calls as uncertain

By PulseAugur Editorial · [1 sources] ·

A bug in Agent Middleware's MCP path has been fixed, addressing an issue where calls were incorrectly labeled as "delivery_uncertain" even when a valid response was received. This misclassification occurred because the system performed a post-dispatch schema check that could fail, leading to the call being marked as uncertain despite completion. Two pull requests have resolved this by ensuring successful upstream results are charged as such, regardless of subsequent schema validation, and by reclassifying unparseable upstream envelopes as "response_rejected" instead of uncertain.
