// TestLSPCodeActionsSplitLintAndFormatCommands verifies the command front door
// preserves LSP CodeActionKind filtering.
//
// `lsp-code-actions` receives `context.only` from ttscserver, not from package
// helpers. This test pins the real dispatcher path so a fix-all request cannot
// expose format actions and a format request cannot expose lint fix actions.
//
// 1. Seed a project with lint and format findings.
// 2. Run `lsp-code-actions` with `source.fixAll.ttsc`.
// 3. Run `lsp-code-actions` with `source.format`.
// 4. Assert each response advertises only its matching command.
//
// @evidence contracts/testing.md#behavioral-verification A project with lint and format fixes produces only the lint command for source.fixAll.ttsc and only the format command for source.format.
// @evidence contracts/testing.md#independent-expectations The requested action kinds and literal single-command lists express the supported filter contract, independently of returned action enumeration.
// @evidence contracts/testing.md#distinguishing-cases One source has a no-var lint finding and, through the empty format block, missing-semicolon format findings, so both command kinds are available; each of the two context.only requests must then return exactly one command, the lint fix-all command for source.fixAll.ttsc and the format-document command for source.format, so neither request can leak the other's action.
// @evidence contracts/testing.md#execution-ownership Calls run lsp-code-actions twice in process through runLSPCodeActionsForTest (source.fixAll.ttsc and source.format) over one temporary project and compares the returned command ids; the commands themselves are not executed here.
