story-point-estimation

Story-point methodology — what points mean (complexity × uncertainty × effort), Fibonacci-progression rationale, team-specific reference-story calibration, velocity-based forecasting as range (mean / min / max / std), anti-pattern surfacing (hours-to-points, velocity-as-productivity, cross-team comparison, inflation). Four modes: estimate / calibrate / forecast / audit. Distinct from planning-poker-protocol (this is the criteria). Mermaid diagrams with optional PNG export.
