Privacy-safe operational telemetry boundary.
Spectre emits through the standard :telemetry module when the host has it
installed. Tests and lightweight hosts may instead provide a
:telemetry_handler callback in runtime options. Telemetry is observational:
callback failures never alter a turn.
Summary
Functions
Emits one privacy-safe event under the [:spectre, ...] prefix.
Functions
Emits one privacy-safe event under the [:spectre, ...] prefix.
When :telemetry is installed, Spectre calls :telemetry.execute/3. A host
may also pass telemetry_handler: as an arity-three function or
{module, function} tuple. Both handlers receive the prefixed event,
measurements, and metadata.
Spectre.Telemetry.emit(
[:execution, :stop],
%{duration_us: 850},
%{outcome: :ok, kind: :action}
)Telemetry is observational. Invalid handlers, exceptions, exits, and throws
are contained and the function always returns :ok. Callers must keep
metadata free of prompts, conversation text, credentials, and raw adapter
errors.
