 - Treat `internal/ingestion`, `internal/parser`, and `internal/deepdoc` as actively refactored code. Prefer collapsing duplicate paths over preserving transitional wrappers.
 - Do not add or preserve deprecated Go APIs just to ease migration inside the repo.
 - Remove commented-out Go code instead of leaving recovery notes in place.
 - Keep package comments and doc comments aligned with the current runtime path, not with migration history.

 - Before editing, inspect the nearest code path that actually owns the behavior.
 - Keep changes small and local unless the task is explicitly a broader refactor.
