Notes and dated annotations
This notes area collects concise, dated entries that illustrate neutral observation of budget documents. Each note is presented as a short technical annotation: it identifies the location in the reference exemplar, enumerates the primitives affected, and records minimal provenance metadata. The entry below shows the structure used for an annotation: header with date and token, a summary of affected primitives, the technical observation, and a reference pointer to the provenance chain. The intent is not to recommend actions but to document how a reader should interpret structural cues such as boundary tags, aggregation formulas, and revision stamps. Notes emphasize reproducible reading: they include exact snapshot timestamps, the sampling method where relevant, and any qualifiers that influence comparability. This approach supports neutral cross-checking between versions and enables machine-assisted extraction of change sets for audit or archival review.
