Point of no return: when a lead becomes permanent

Per game, order score ticks by (game-clock, ts); a margin threshold's point of no return is the first tick from which |home_score-away_score| stays >= threshold to the end. Reads only the score path, not model/market prob.

What it means

For each game the module reads only the score path and finds the point of no return: the first moment a margin threshold holds to the final whistle. The pattern is intuitive but now measured -- small leads (2 runs) become safe around the middle innings in most games, while large leads (5 runs) are, by definition, built later and in far fewer games. This module carries MLB and international soccer only; the NBA cut is not present in this artifact.

Caveats & confounds

Descriptive game-flow only, no edge/ROI claim. It reads the score path, not any model or market probability, and a (sport, threshold) cell below the 10-game floor is masked from the headline (e.g. soccer above a 1-goal gap).

Method. Per game, order score ticks by (game-clock, ts); a margin threshold's point of no return is the first tick from which |home_score-away_score| stays >= threshold to the end. Reads only the score path, not model/market prob.

Novelty & prior art

Prior art. Descriptive 'point of no return' / clinch-time measurement, in the tradition of safe-lead heuristics (e.g. Bill James NBA safe-lead) and win-probability clinch points. Not a new method; do not claim first-ever.
