- every scratch file lives in `$TMPDIR/x_<pid>/` (tmp_dir/tmp_path in prelude.ludic), removed by main's new dispatch() → tmp_cleanup(); X_KEEP_TMP=1 keeps it. `x test` and `x check-*` may now run together. - `x test-lsp` (tools/x/lsp_test.ludic) replaces tools/test-lsp.py: the whole request stream is framed into one stdin file, the server runs to `exit`, and the response stream is parsed back by request id; adds a check that ludicc's own error is published on save - tools/x/forgejo.ludic replaces tools/ci/forgejo_release.py (curl with a 0600 header file; the token is no longer on the command line; LUDIC_FORGEJO_API for forks) - `x docs-palette --check` regenerates into scratch and compares, so the drift guard judges the working tree rather than git HEAD; the generator no longer emits a trailing blank line the formatter rejects - `x test-tools`: exit 2 from test-lsp / test-grammar.js is a visible skip, never a pass; the widget-prop test uses the `id: Root` syntax - tools/test-grammar.js: current vocabulary (property/model/handler/ prefab/scene/event/become/@Queries), LUDIC_NODE_MODULES, exit 2 on skip - tools/atlas.ludic rewritten in the current language (it did not compile) - operators.ludic / os.ludic registered in the suite - json.ludic: j_quote() writer helper Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
