A line is a claim.
Connecting two points suggests that the interval between them belongs on the same curve. Scope leaves a break when a value is missing or invalid, time moves backwards, a coordinate repeats, or the chosen gap threshold is exceeded.
It preserves file order. It does not fill values, sort records, smooth a curve, infer units or decide whether a measurement is scientifically plausible. A blank is never silently converted to zero.
Formats, limits, and what the report means
The first nonblank CSV record supplies the column names. Quoted fields, escaped quotes and multiline cells are supported. Comma, semicolon and tab separators are available. Dates must be valid YYYY-MM-DD values or ISO timestamps with an explicit timezone. Numbers must be finite decimal values; scientific notation is accepted.
Files are limited to 5 MB and 50,000 data records. The curve uses all valid observations; point markers are sampled above 1,200 observations for rendering speed. Record numbers refer to logical CSV records, including the header, rather than physical lines inside quoted fields. The report describes parsing and plotting decisions, not a certification of data quality.
