+Bug (reproduced live against 0.8.1): for a bank whose disposition and

+MemoryEngine.list_banks returned bank_utils.list_banks rows straight from
+those columns with no overlay. The two endpoints disagreed for the same bank.

+This test sets disposition + mission through the config path (so the legacy

+"""Regression: sub-batch slices that each span MULTIPLE extraction chunks must
+keep full chunk coverage on BOTH the sync (inline) and async (submitted) retain
+paths.
+
+Two distinct bugs hid behind the same symptom — ingesting a large plain-text
+document dropped most of its body (and any fact past the first slice). Both only
+trigger when an oversized single item is split into sequential sub-batches whose
+*slices each re-chunk into several extraction chunks* (the default config: batch
+tokens 10k → ~30k-char slices, re-chunked at 3k → ~10 chunks/slice):
+
+1. chunk_index offset (sync + async). retain_batch_async advanced the per-document
+   chunk_index cursor by re-chunking ``item["content"]`` AFTER the orchestrator
+   had consumed (popped) it — ``chunk_text("")`` returns ``[""]`` (count 1), so
+   the cursor moved by 1 per sub-batch instead of by the real chunk count. Later
+   slices restarted ~1 slot in, colliding ``chunk_id = {bank}_{doc}_{index}`` and
+   overwriting earlier chunks via upsert.
+
+2. whole-document recovery skip (async only). All sub-batches of one submitted
+   operation share one ``operation_id``; the first slice stamps the document into
+   ``result_metadata.facts_committed_document_ids``. The crash-recovery fast-path
+   then saw every later slice's document already "committed" and skipped
+   extraction entirely, so only the first slice survived.
+
+The existing #1888 coverage tests use ``RETAIN_BATCH_TOKENS=100`` (a ~300-char
+budget, under the chunk size) so every slice collapses to ONE chunk — which masks
+both bugs (offset-by-1 happens to equal the real count, and a 1-chunk doc isn't
+re-sliced). These tests size the body so each slice fans out to ~6 chunks, with
+globally-unique tokens so no chunk-hash dedup hides a dropped slice, and assert
+full coverage + contiguous indices + a needle planted in a late slice.
