Read exact retained FFIEC expressions and declared engine coverage

Exact retained FFIEC051 September 30, 2026 v300 taxonomy and bounded edit engine; 39 required Schedule RC body fields and two March-only memoranda. Other schedule applicability, unexecuted functions and prior accepted CDR history remain explicit blockers. Candidate historical comparisons require independently reviewed exact-quarter workpapers and same assigned RSSD; no operator waiver or successful subset makes a filing submission-ready. Staff reporting write plus recent step-up for execution; operator reporting read for evidence.
