FailCallbackBody

Request body for the worker fail callback.

Attributes: error: Error message from the container. tenant_id: Tenant UUID (passed by container for routing). steps_executed: Iterations completed before the failure. usage: Accumulated LLM token usage. A failed run still burned every token it burned before failing, so this is carried on the failure path too and is NOT refunded.

ComputerUseUsageBody

Accumulated Anthropic token usage reported by the container.

The worker cannot bill from inside its isolated Cloud Run container (no Redis, no Postgres, no CreditManager – same isolation as the D-13 deviation documented in src/workers/computer_use_worker.py), so it counts tokens across every turn of the computer-use loop and reports the totals here. ComputerUseExecutor._meter_llm_usage runs the reserve/settle against the tenant’s real balance on receipt.

Missing receipts remain unknown; required counters never default to zero.

Attributes: model: Model the container actually called (priced against this). input_tokens: Summed usage.input_tokens across all turns. output_tokens: Summed usage.output_tokens across all turns. cache_creation_input_tokens: Summed cache-write tokens. cache_read_input_tokens: Summed cache-read tokens. turns: Number of provider round-trips.
