Constant MAX_TREND_POINTS 

pub const MAX_TREND_POINTS: usize = 120;

Available on crate feature vcs-git only.

Maximum number of time points. Each point is a full history walk, so the count is capped to bound the worst-case runtime on deep histories (issue #333’s “very deep histories: cap point count”). 120 points is a decade of monthly snapshots — far beyond any practical trend chart.
