- Add `_strip_image_b64_payloads` filter: rewrites `data[*].b64_json` in
image-gen responses to a 4-byte placeholder before the cassette is saved.
Image-edit and image-gen cassettes (193 MB / 184 MB / 104 MB / ...) will
shrink to <100 KB on next record. Tests assert response shape only, so
coverage is preserved.
- Add `_normalize_multipart_boundary` filter: replaces httpx's per-request
random multipart boundary with a fixed string in both Content-Type header
and body bytes. Audio-transcription / Whisper tests have been effectively
unmocked — every CI run hit live providers and was silently capped at
MAX_EPISODES_PER_CASSETTE=50. Both record and replay now see identical
bytes; the safe_body matcher works.
- Fix test_evals_api.py body poisoning: replace `int(time.time())` in eval
names with `hashlib.sha1(test_node_name)[:12]`, add a function-scoped
`managed_eval` fixture that creates and deletes the eval, and switch
`get_eval` / `update_eval` from `list_evals().data[0].id` (which made
the URL vary by run) to `managed_eval.id`. Net coverage gain: delete is
now actually exercised.
- Swap arxiv PDF URL in BaseOCRTest for the in-repo `dummy.pdf` (589 B)
served via sha-pinned jsdelivr.
- Swap etsystatic image URL in BaseLLMChatTest.test_image_url for the
in-repo LiteLLM logo (9.2 KB) served via the same jsdelivr pin.
- Add `tests/llm_translation/test_vcr_filters.py` with 14 unit tests
covering both new filters: replacement, idempotency, nesting, content-
length update, two-distinct-boundaries-converge-after-normalize, etc.
Cassettes recorded with the prior patterns will mismatch on the first CI
run after merge; recommend flushing the cassette Redis once (post-merge)
so re-records save under the new format from the start.
