One correlated terminal fact from an evidenced one-shot execution.
Sent as {reference, observation} by the execution caller before returning.
A preceding SessionObservation establishes identity only. :outcome is the
legacy execution result before JSON/fork convenience projections; :parsed_result is the last bounded native
turn.completed or turn.failed JSON object, independent of process outcome.
:child_status and :child_signal are raw native reports, never inferred
from JSON, transport closure, or a pre-spawn failure. :termination records
protocol/transport termination, while :reason records timeout or limit
cancellation. :cleanup, :scope, and :guard_close are separate facts;
missing facts remain :unknown (missing child status/signal remains nil).
Process-group confirmation does not cover descendants escaping that group.
:stdout and :stderr are bounded prefixes, including on failure.
