What

When reassembling a batched tool call fails, the error is now recorded once per tool call instead of every time, and the report includes the tool name. A repeatedly failing batch no longer floods telemetry.

Details
  • De-duplication uses a per-host set keyed by tool-use id.
  • Unconditional.
Evidence

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