derived_rule

Which rule made a file derived or not, in the order the classifier tries them; the first that applies wins. A vocabulary for lvcs status and lvcs explain <path>, never a telemetry attribute value.

Value	Meaning
`gitattributes`	A `.gitattributes` line decided: a negation (`-linguist-generated`, `linguist-generated=false`, `-lvcs-derived`, `lvcs-derived=false`) makes the file not derived, and is tried first; a positive attribute (`linguist-generated`, `linguist-generated=true`, `lvcs-derived`) makes it derived, and is tried after `lvcs_toml`.
`lvcs_toml`	A the generator's `writes` pattern in `lvcs.toml` at its approved heads decided, tried after a `.gitattributes` negation: a pattern makes the file derived, and a `!` pattern makes it not derived.
`pattern`	The path matches `DERIVED_PATTERNS`, tried after every `.gitattributes` and `lvcs.toml` rule.
`marker`	One of `DERIVED_MARKERS` is in the file's header, tried last.
`none`	No rule makes the file derived, or the path is in `NEVER_DERIVED`, which is checked before every other rule.
