Function attribute_record

pub fn attribute_record(
    rec: &CarvedRecord,
    tables: &[LiveTable],
    page_table_map: &BTreeMap<u32, String>,
) -> Attribution

Expand description

Attribute one carved record to a tier given the live tables and the page→table map. Pure (no DB access) so it is directly unit-testable.

Tier 1 (CERTAIN): source is an in-page class (RecoverySource::InPageFreeBlock or RecoverySource::FreeblockReconstructed) AND the record’s page is in page_table_map → Attribution::Known.
Tier 2 (INFERRED): source is RecoverySource::FreelistPage → match the record’s shape against tables; exactly one match → a guess, more than one → ambiguous, none → Attribution::Unattributed.
Tier 3 (UNATTRIBUTED): RecoverySource::DroppedTable, any other source, or a shape matching no surviving table.
