  "brief": "**Philosophy and fit.** Make claims inspectable and provenance visible. Suitable for institutional research, public record collections, policy trackers, and structured investigative resources.\n\n**Visual grammar.** Use a sober index with compact search, a faceted records table, and a persistent evidence summary. Record pages distinguish the statement, its supporting material, the applicable dates, and interpretation. A humanist sans, tabular numerals, thin rules, white surfaces, navy text, and restrained ochre status marks produce a documentary character. Status labels always include text.\n\n**Specimen and flow.** *Public Works Ledger* contains explicitly fictional contracts and organisations. Visitors filter records, inspect a single assertion, and open its source excerpt beside the assertion. Supporting states show conflicting fixture evidence and a record whose source is unavailable.\n\n**Adaptation and identity.** Mobile turns rows into labelled records and places source material after its associated claim. Preserve provenance, date context, and the distinction between evidence and interpretation; avoid unsupported score badges, dashboard ornament, and graphs that imply unrecorded relationships. Motion is unnecessary. **Effort: medium.**",
