What problem does it solve? Genealogical research accumulates assertions from many independent records, and without chronological arrangement it is hard to see whether they describe one coherent life, where documentation is missing, or whether two same-name people have been conflated. This Skill arranges assertions into GPS-conformant timelines persisted to research.json. ## Core Features & Use Cases - Timeline construction: Builds person timelines, hypothesis-testing candidate timelines, or refreshes existing ones, combining related assertions into single events with standardized places and computed distances between consecutive events. - Gap analysis: Identifies negative evidence by checking expected census years (read from the FamilySearch wiki per country), missing marriages, deaths, and military records, each classified by severity. - Identity testing: Evaluates whether records cohere into one life using age progression, geographic plausibility against era travel speeds, and family consistency, returning a Pass, Fail, or Inconclusive verdict. - Use Case: After linking 1850 and 1860 census assertions to Patrick Flynn via person-evidence, ask for a timeline to see the events in order, spot the missing 1870 census as a high-severity gap, and test whether a third record belongs to the same man. ## Quick Start Build a timeline for Patrick Flynn from the assertions already linked to him and show me any gaps.
