ProbeLabsviewing a historical runWhen GetFloat addresses a JSON number token that is parseable as a float64 value, the parser shall return the corresponding float64 result.
Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When GetFloat addresses a JSON number token that is parseable as a float64 value, the parser shall return the corresponding float64 result. ArrayEachErr is the io.EOF-aware ArrayEach variant where the callback may stop iteration by returning an error; the returned count includes the element whose callback stopped iteration.
the parser shall always satisfy !addressed_value_is_number | !raw_number_token_is_float_parseable | returns_getfloat_value

Rationale & tags
Why this requirement exists, and how it is categorised.
GetFloat is the public floating-point accessor for callers that know the expected numeric type and still need defined failure behavior.

GetFloat meets !addressed_value_is_number | !raw_number_token_is_float_parseable | returns_getfloat_value: non-Number types error out with no value, and a Number token is returned via ParseFloat(v), which returns MalformedValueError when parseFloat fails (the !float_parseable disjunct). The ArrayEachErr aspect in the description also holds: arrayEachErr increments count BEFORE invoking the callback, so a callback that stops via io.EOF (graceful, nil error) or any other error returns a count that includes the stopping element — TestArrayEachErr confirms count==2 on EOF-at-2 and count==3 on error-at-3.

Obligations
What this requirement must witness to be considered satisfied — the required evidence, and the tests that discharge each one.
The tests that discharge each obligation aren't available for a historical run
The evidence matrix behind each obligation comes from the live audit index, which can't be rebuilt for a past commit. Nothing here means unknown — not that the requirement has no obligations.

MC/DC truth table· 4 rows
Each row assigns the formula's conditions (T/F) and shows the Result— the formula's value for that input row, not a test pass/fail. A row proves a condition when flipping only that condition flips the outcome. The test that covers each row is linked.
