// TestLSPFormatPathsHonorEntryIgnores guards scoping parity across the four exercised
// formatting front door. A rules-bearing entry is important here: it proves
// ignores are preserved even when the config is not an ignore-only entry.
//
// The rules-bearing ignore entry must apply to each exercised formatting front door, rather than only the ignore-only resolver branch.
//
//  1. Configure a source ignored by an entry that also carries a lint rule.
//  2. Require empty action/edit responses and unchanged source from each format path.
//
// @evidence contracts/testing.md#behavioral-verification A rules-bearing entry ignoring src/main.ts yields no action, no disk edit, an empty buffer edit and unchanged format-dispatch bytes.
// @evidence contracts/testing.md#independent-expectations Empty action/edit expectations and original const value = 1 source bytes independently require a no-op from each front door.
// @evidence contracts/testing.md#distinguishing-cases An ignore entry containing no-var-off rules distinguishes retained ignores from a special ignore-only entry; sibling default hosts supply positive formatting controls.
// @evidence contracts/testing.md#execution-ownership All requests use the existing native Go unit process and a private ignored fixture; no native binary, evaluator or formatter subprocess is invoked.
