Input CSV File

How it fits

Typical backends

Caveats

• Hard constraintdelimiter is a single character — use a comma for CSV or a literal tab escape for TSV, which is unescaped at startup; multi-character separators are not supported.
• I/O contractParsing follows the common double-quoted-cell convention, collapsing a doubled quote to a literal one and splitting unquoted fields on the delimiter. All cell values stay as strings, so downstream stages must cast typed columns themselves.
• Parameter interactionhas_header treats the first row as column names when on, and otherwise leaves the header empty and reads every row as data.
• State lifetimerepeat re-emits the directory in a loop at the fps rate when on, and stops after the last file when off; has_header, repeat, fps, and the bound slot are all hot-swappable while delimiter binds once at startup.
