Limitations. Growth is computed from the agency's own published award and authorized amounts. Stated reasons are quoted verbatim from board resolutions, which are written to obtain approval and reflect the agency's own framing. Increases absorbed within contingency or below board approval thresholds never appear in public documents and are not counted here. This memo supplies a missing variable; it is not a recommendation.
