• File cli/repo_timeline_horizon_test.go — part of check-in [ee3ccc7c67] at 2026-10-22 17:21:12 on branch feat/horizon-cones — feat(history): render a horizon boundary as the horizon

  A parent the origin labelled below a structural horizon is the horizon itself (draft-fossil-horizon-00 5.4), but the history views showed it as a bare parent hash, and the ancestry walk tried to read an event for it.

  LogEntry and TimelineEntry gain HorizonParents, the subset of Parents that carries a boundary label; Ancestry ends at such a parent without an error; repo timeline prints it as "parent: <hash> (horizon)". An absent parent that is not labelled is transit and renders as before. (user: [email protected], size: 1586) [annotate] [blame] [check-ins using] [more...]
