Evidentiary Lacunae for Historical Narratives","opportunity_summary":"Test whether replacing unsupported connective prose with bounded, labeled, recoverable evidentiary lacunae helps readers distinguish documented sequence, conjecture, and unknown linkage better than ordinary prose annotations, without implying that missing evidence proves nonoccurrence.","adopter_authorizer":"The responsible historian and editor, subject to archive rules, editorial review, and review by relevant source or community stewards.","scores":{"meaningful_impact":{"score":3,"rationale":"Reducing false confidence and preventing conjecture from being reproduced as fact could improve historical interpretation, but the packet provides no evidence about how often unsupported bridging occurs or the magnitude of resulting errors."},"stakeholder_pull":{"score":2,"rationale":"Historians, editors, readers, students, and represented communities are identifiable stakeholders, but the packet contains no expressed demand, adoption inquiry, or evidence that they prefer a structural lacuna convention."},"incremental_advantage":{"score":3,"rationale":"The protected structural interval is meaningfully distinguishable from caveats in prose or footnotes and has a testable calibration claim, but no results show that it improves interpretation over those annotations or avoids added confusion."},"distinctiveness_plausibility":{"score":3,"rationale":"Organizing interpretation around a bounded, recoverable absence is a specific mechanism composition, but prior art is explicitly unsearched across critical editions, archival-silence practices, uncertainty notation, and visual timelines."},"technical_implementability":{"score":4,"rationale":"Creating reversible passage variants, retaining cut text, labeling gaps, and restoring baseline prose require ordinary editorial and presentation capabilities; the main difficulty is making disputed or shifting gap boundaries legible without false precision."},"adoption_authority_feasibility":{"score":4,"rationale":"The candidate identifies the historian and editor as decision authorities and makes archive rules and relevant stewards explicit, although multi-party review may complicate use for accounts involving contested or marginalized histories."},"evidence_readiness":{"score":4,"rationale":"The candidate specifies six short acknowledged-gap passages, a direct comparison with prose annotations, reader interpretation outcomes, separate problem and intervention falsifiers, and reversible rollback conditions."},"safety_net_benefit":{"score":4,"rationale":"Recoverable notes, preservation of adjacent context, prohibited concealment and source alteration, affected-party review, and restoration of baseline passages provide strong safeguards, though they cannot fully eliminate aestheticization or evidence-of-absence errors."},"scalability":{"score":3,"rationale":"A reusable editorial convention

review."}},"score_confidence":"MODERATE","costs":{"first_evidence":{"band_2026_usd":"10K_TO_50K","scope":"Prepare two reversible versions of six short passages, conduct historical-source and
