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.Box represents 2D bounding boxes with P [2]pgtype.Vec2 and Valid bool fields
  2. pgtype.Box implements driver.Valuer returning formatted box string for valid boxes and nil for SQL NULL
  3. pgtype.Box implements sql.Scanner parsing box string representations and handling nil as invalid
  4. pgtype.Box implements ScanBox and BoxValue for pgx native box conversions
  5. pgtype.Box encodes and decodes in text and binary wire formats using pgtype.Map
  6. sample helper functions provide box creation, area calculation, point containment, formatting, and wire conversions
