Capture a local source for a completed quarter without retaining it: values and categorised missing items

Local source kinds declare exact retained FFIEC051 September 30, 2026 v300 form positions; nine kinds account for every position of RC-R Part I, RC-B, RC-K, RC-M, RC-O, RI-A, RI-B Parts I and II and SU. A preview captures a completed quarter from retained core data without retaining it: every declared position is a value or a missing item categorised not_retained, reviewed_input, activity_condition or source_unavailable, never a zero. The matrix reports bindings, captions, instruction digests and declared coverage; it asserts no requirement or completeness. Operator reporting read.
