# Archival Addendum An Archival Addendum is a later, explicitly dated addition that corrects, qualifies, or contextualizes an existing record without pretending the new material was part of the original source. ## Typical bases - Owner-supplied contextual correction - Recovered contemporaneous note or document - Newly integrated screenshot or message - Audio transcription or speaker clarification - Identity or name resolution - Later external verification - Cross-source reconciliation ## Required structure Each addendum should identify the record it applies to, the earlier interpretation being revised, the new information, its provenance, what the correction changes, what remains unresolved, and whether original transcription or source content was altered. An addendum supplements the record; it does not erase the interpretive history. ## Naming and metadata Use `Addendum - Short Descriptive Title.md`. Record `added_date`, `basis`, `applies_to`, `related_events`, and `status`. ## Navigation See [[Index - Archival Addenda]], [[Journal Entry]], [[Audio Transcription]], and [[Screenshot Record]].
