To keep changes minimal, call ensure_text_embeddings with a temporary limit and the wrapper can accept a `motion_ids` argument. The script should record audit events for items that still fail after retry. + +**File:** `scripts/rerun_embeddings.py` (modify) +**Test:** `tests/test_rerun_embeddings.py` (modify — existing test) + +Implementation notes: +- Add parser.add_argument("--retry-missing", action="store_true", help=...). +- After first ensure_text_embeddings, expect a 5-tuple. If retry_missing and failed_ids exist, call a second short pass: call text_pipeline.get_embeddings_for_ids(db_path=db_path, ids=failed_ids, model=model, batch_size=max(1, batch_size // 2)). Option: reuse ensure_text_embeddings by adding optional parameter to accept a list of motion ids (we added returning failed_ids earlier; modify text_pipeline to accept motion_id list). Implementation choice: add new helper function in text_pipeline called ensure_text_embeddings_for_ids, and use it here. +- Update tests/test_rerun_embeddings.py to monkeypatch the new text_pipeline helper and simulate that first call returns failed_ids and second call resolves them; assert rerun called accordingly and summary contains expected fields. + +Test changes: +- Update tests/test_rerun_embeddings.py to reflect that text_pipeline.ensure_text_embeddings returns five values and to simulate --retry-missing behavior. +- Keep the existing expectations in the test (we will extend them to include failed_ids handling). + +Verify: +- pytest -q tests/test_rerun_embeddings.py +- Manual run: python scripts/rerun_embeddings.py --db-path data/motions.db --retry-missing + +Commit: +- feat(scripts): add --retry-missing to rerun_embeddings and retry failed items with smaller batches + +--- + +### Task 2.3: similarity.compute — DB-side safety filter to avoid trivial 1.0 matches +**Owner:** implementer +**Estimate:** 3 hours +**Depends:** none (reads existing DB) +**Description:** Add a small DB-side filter before inserting similarity rows that filters out suspicious 1.0 matches between different motions when the titles are extremely short (heuristic: identical titles with length < 12 characters).

Monkeypatch duckdb.connect to return rows such that compute_similarities will produce rows_to_insert including a 1.0.
