Summary-only and legacy aggregate fallback

This generated note uses fixed synthetic values. It records the compatibility boundary enforced by IndividualEntryExporter.extractIndividualSamples.

Capture state	Canonical archive present	Extracted entries	Result
not_requested	no	1	A daily aggregate is emitted with entry_kind: daily_aggregate.
legacy_unavailable	no	1	A daily aggregate is emitted with entry_kind: daily_aggregate.
partial	no	0	No aggregate is substituted for requested canonical capture.

Summary-only exports and legacy records may use aggregate fallback because source-event identity is unavailable by design. When canonical capture was requested, an empty, failed, unsupported, skipped, or partial canonical query is not replaced by a daily summary that could look like a source event.
