# `TypeSafeSDK.Telemetry`
[🔗](https://github.com/nshkrdotcom/typesafe_sdk/blob/v0.4.1/lib/typesafe_sdk/telemetry.ex#L1)

Privacy-oriented semantic spans above Pristine's attempt telemetry.

Events are `[:typesafe_sdk, :evaluate, :start | :stop | :exception]`,
`[:typesafe_sdk, :answer]`, and `[:typesafe_sdk, :batch, :cancelled]`. Durations
use native monotonic units.
Automatic metadata never includes state, questions, bodies, headers, API keys,
exception reasons, stacktraces, or raw errors. Explicit `telemetry_metadata`
is nested under `:caller`; supply identifiers, not customer content.

A brutally killed process cannot emit a terminal event. Batch timeouts are
observable by the owning stream; physical transport cancellation remains a
transport capability, not a promise made by these events.
