Third importer increment — the write path, fully testable without UI. - commit.ts: commitBatch streams classified rows, applies insert/update per the conflict policy via the adapter (each row in its own try/catch so valid rows still land), records every action in import_batch_rows, and keeps live counts on the batch header. undoBatch hard-deletes a batch's inserted rows (port-scoped); a delete blocked by a dependent FK is reported, not forced, and the batch flips to `undone` only when every inserted row was removed. - import worker: replaced the no-op placeholder with the real processor — loads the batch, re-reads the uploaded file from storage, parses, and runs commitBatch under the batch's mapping + policy. Marks the batch failed on error. Concurrency 1 so imports don't race each other's dedup lookups. Tests: commit (skip/insert/error counts + per-row ledger + real inserted entity), undo (removes exactly the inserted row, flips status), and update-matches overwrite. 2 passing. Engine is now functional end-to-end at the service layer: parse → map → dry-run → commit → undo. Remaining: 4 FK adapters, API routes + permission, wizard UI + history.
