One TransectProvider per [TRANSECTS] entry in the project. Owned by a project-scoped TransectRegistry. Single source of truth: the editor's list pane, property panel rows (QPropertyModel), station-elevation grid, and the cross-section chart all bind to the same provider and refresh through its Qt signals ([[feedback_mvc_synchronized_uis]]).

Storage invariant: station-elevation points are strictly ascending in station (X). Every public mutator validates the post-mutation state and refuses any operation that would violate it — emitting mutationRejected(reason) so the caller can surface the rejection. Bulk operations are atomic: either all points are updated, or none.

Mirrors CurveProvider (Phase 6.7.1) in shape; the additional surface area covers Manning's roughness triple, bank stations, encroachment stations (BQ-TR-02 Reading B), modifier triple (xFactor / yFactor / lengthFactor), and comments.
