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.

Case
HOW- Goal

Contract
- humanize.FormatInteger with an empty format string returns "12,345.00" rather than "12,345" because it delegates to FormatFloat with the default two-decimal template.
- humanize.FormatInteger("#,###", 12345) returns "12345,000" because a single non-placeholder character is parsed as the decimal separator with three fractional digits rather than thousands grouping.
- humanize.FormatInteger("#,###.", 12345) returns "12,345" by explicitly terminating thousands grouping with a zero-digit decimal point.
- humanize.FormatFloat("#,###", 12345.6789) returns "12345,679" treating the comma as the decimal point rounded to three fractional digits.
- humanize.FormatFloat("#,###.", 12345.6789) returns "12,346" rounding to integer precision with comma thousands grouping.
