table_write_csv — FILEIO `table` op

• Data kinds: table → text

• Call: import fullseye as fs; fs.ledger.table_write_csv(table, *, units, meta) (to call the implementation directly, import fileio; fileio.table_write_csv(table, *, units, meta); from the registry, opsfileio.get("table_write_csv"))

• GPU: none (CPU reference implementation only)

Usage

Writes a table with units and provenance as CSV text readable by pandas and MATLAB (text).

> The detailed description below is the original text — the summary and the headings are translated.

table は {列名: 1-D 配列}。units は全列の単位を同じキーで持つ辞書、meta は source(出所)、generated_at(ISO 8601)、coordinate_meaning(座標の意味)を必ず持つ。1 行目は列名、2 行目は # units:、続く # key: value 行はメタデータ、その後がデータ。pandas.read_csv(StringIO(text), comment="#") で列名と値を読み、MATLAB ではコメント行を除外して readtable で読める。浮動小数は Python の repr で丸めず、列長不一致・単位欠落・無限値は拒否する。

呼び出し例: table_write_csv({"x": [1.0]}, units={"x": "mm"}, meta={"source": "caliper", "generated_at": "2026-10-31T12:00:00+09:00", "coordinate_meaning": "x is right-handed"})。
