Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. pgtype.Point represents 2D coordinates with Vec2 X, Y float64 and Valid boolean
  2. pgtype.Point implements driver.Valuer formatting point coordinates string and nil for SQL NULL
  3. pgtype.Point implements sql.Scanner parsing point string representations and handling nil as invalid
  4. pgtype.Point implements ScanPoint and PointValue for pgx native point conversions
  5. pgtype.Point encodes and decodes in text and binary wire formats using pgtype.Map
  6. sample helper functions provide point creation, distance calculation, formatting, and wire conversions
