 ### Changed
 - **`gstack-pregate init` drafts from the repo (#3268).** It prints the languages it found and the runner each language's tests get, maps each file the import graph cannot place to the tests of the nearest directory above it, and lists the rest as `TODO` (as it does past the 256-entry schema limit). It never writes `[]`, which would clear a file without a test.
 - **Review fixes on the Dart port.** A `cd` inside a pipeline, an alternative, a background job, shell control flow, a command substitution or a redirected subshell now leaves a CI lane's test set unknown (it may run any test) instead of resolving later paths against the wrong directory, which could drop a platform obligation. Dart directives are read to their `;` whatever the line indentation, metadata before a directive and semicolons inside a URI are handled, and nested block comments are skipped, so an unindented conditional import or a long `show` list no longer loses its edges.
-- **Gate integrity:** new free regressions in `test/pregate-non-js.test.ts` (Django, assets and licence, init, and the two review fixes, each with a negative control) and `test/pregate-dart.test.ts`. Each new positive case fails on the tree before this change. No existing test, threshold, trial count or case kind changed; `test/helpers/pregate-fixture.ts` only reports more about a failed git spawn.
