Research direction

This is a catch-all tracker rather than a scoped task, and it lists linked work in PRs gh-153571, gh-153573, gh-153574, gh-153575, gh-153576, gh-153577, gh-153583, gh-153584, gh-156209, gh-157374, gh-157413, gh-157437, gh-157450, gh-157465, and gh-157534. Review those PRs to identify any remaining parser speedup with a defined entry point and completion criterion; this issue alone names no file or test.
