// TestUnicornFilenameCaseUpstreamInvalidFilenames checks the retained invalid
// filename/options table against independent literal diagnostic messages,
// including rename samples and their order.
//
// Message text is load-bearing: the disjunction list format, the configured
// case order, the leading-underscore prefix, the lowercased extension in
// rename samples, and the cartesian rename enumeration all surface here, so a
// drift in any helper breaks an exact string.
//
// 1. Lint a virtual file for each filename/options pair.
// 2. Assert exactly one finding carrying the authored literal message.
//
// @evidence contracts/testing.md#behavioral-verification The real rule evaluates the retained invalid filename/options matrix and requires exact authored diagnostic messages.
// @evidence contracts/testing.md#independent-expectations Literal supported case conversions and independently authored expected alternatives distinguish wrong normalization, message ordering and missed reports.
// @evidence contracts/testing.md#distinguishing-cases The retained table distinguishes default and explicit cases, acronyms, underscore prefixes, middle extensions, directories and ordered rename alternatives.
// @evidence contracts/testing.md#execution-ownership TestUnicornFilenameCaseUpstreamInvalidFilenames owns its retained literal paths/options as a discoverable Go unit entry; engine/configuration operations run in the shared process using virtual or isolated fixture paths, without installing a consumer, native build or product host.
