 - The plan's "go doc fallback accepting a promoted member" cannot be tested as worded: `go doc` does not resolve promotion (plan 11.1-02 found this), and the index handles promotion itself. `TestIdentifierGoDocFallback` shows that the fallback accepts a declared member, caches answers and never passes a non-identifier to the argv. It also shows that a member promoted from another package is still a problem after the fallback runs.
 - `testdata/violations/snippet-unparsable-go/lib/lib.go` does not parse on purpose, so a repository-wide `gofmt -l` lists it. No gate runs gofmt, and the go tool ignores `testdata`.

+- **Found during:** the final cleanup sweep (two 48 MB `/tmp/tmp.*` directories from the Task 1 baseline refusals)
+- **Issue:** Every stage removed its `mktemp` directory with a RETURN trap, but a refusal exits from inside the stage, so the trap never ran.
+- **Fix:** An EXIT trap removes every stage's scratch paths. The self-test now copies `examples/` with `tar --exclude='examples/*/bin'` instead of `git ls-files`, so a `PHASE11_1_ROOT` copy without `.git` works. A planted refusal against a scratch copy left the `/tmp/tmp.*` count unchanged (29 before and after), and the two leaked directories were removed.
