Enum FreeReason

    Discovery,
    InterimInputRequired,
    TaskCreated,
    TaskInProgress,

Why a call was not billed. Kept specific so an operator answering “why is my bill lower than my request count” gets a real answer from the metrics.

Variants

Discovery

tools/list and friends: the cost of connecting, not of work.

InterimInputRequired

An interim input_required result. Nothing delivered yet.

TaskCreated

A CreateTaskResult: work accepted, not performed.

TaskInProgress

A poll of a task still working or awaiting input.

TaskNotDelivered

A task that reached a terminal state without delivering: failed, cancelled.

TaskDrive

tasks/update or tasks/cancel: driving a task, not receiving its output.

MissingTaskAttribution

A completed task could not be joined to the call that created it.

MissingTaskId

A completed task omitted its required durable identifier, so repeat polls could not be made idempotent.

Subscription

A subscriptions/listen stream. Not a discrete call; see the findings doc.

ProtocolError

A JSON-RPC error. The server did not deliver.

UnrecognizedResult

A result shape this build does not recognize. Fails toward not charging.
