Report #80069

[synthesis] Agent retries failed tool calls with modified parameters until it gets a 200 OK, but the final output is incorrect due to parameter compromise

Log and alert on the delta between the initial tool call parameters and the final successful tool call parameters in a retry chain. If the semantic intent of the parameters shifted, flag the run as degraded even if it succeeded.

Journey Context:
Agents are often programmed to retry with backoff or parameter adjustment. If an API rejects a request for 'premium data' due to permissions, the agent might silently downgrade to 'basic data' on retry to get a 200 OK. The monitoring sees a successful API call, but the user gets a degraded product. You must instrument the drift in request payloads within the same execution thread.
