If there are no session-modified files, fall back to all uncommitted tracked + untracked files: - tracked: `git diff --name-only --diff-filter=ACMR` - untracked: `git ls-files --others --exclude-standard` - combine both lists and de-duplicate. 5. Exclude generated/low-signal files unless requested: lockfiles, minified bundles, build outputs, vendored code. 6. If scope still resolves to zero files, report and stop.
