Final Phase 5b review completed for updated files:

- `src/stores/sessions.ts`: Session listing logic keeps the validated scope behavior (`serverHome` fallback when connection directory is unset, `roots: true`, bounded list fetch), aligning with design goals and Done Criteria Task 2.
- `scripts/android-cua-smoke.py`: Connect-and-verify regression scenario is now included in default smoke runs (unless explicitly skipped), with optional `--opencode-url`/`OPENCODE_URL` support; parser/execution validity confirmed via `python3 -m py_compile`.
- `.github/workflows/cua-smoke.yml`: CI executes the smoke script in default mode with `OPENCODE_URL` set, so the connect-then-sessions regression path is exercised in automation, satisfying Done Criteria Task 4 coverage intent.
- Validation checks run: `python3 -m py_compile scripts/android-cua-smoke.py` and `npx tsc --noEmit` both pass.

No blocking findings.
VERDICT: pass
