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. humanize.ParseBytes parses decimal SI byte size strings into integer byte counts
  2. humanize.ParseBytes parses binary IEC byte size strings using base-2 multiplier units
  3. humanize.ParseBytes returns an error for empty or invalid byte size strings
  4. humanize.RelTime computes human-readable relative duration descriptions between timestamps
  5. humanize.SI formats numbers with metric unit prefixes and ParseSI parses prefixed metric strings back into magnitude and base unit
