fix(examples): rerun and grade document-field extraction with the measured recipe - #622
Conversation
…sured recipe The example sent the document schema only as response_format. SIE applies response_format as a decoding grammar, so the model never read the field descriptions; that recipe scored 75.64 on the 546 confirmation documents. The measured recipe also puts the schema text in the system message and raises the output cap to 8,192 tokens; it scored 91.03 and was non-inferior to GPT-6 Luna in the pre-registered test. - run.py builds the measured request and sends one document or a whole published set to any SIE endpoint through sie_sdk.SIEClient; --dry-run rebuilds the set offline and checks the published body sha256. - fetch.py downloads the pinned Omni rows and images and the published replies, checking every size and sha256. - score.py grades replies with a standard-library port of OmniAI's json.ts and json-diff 1.0.6 (both MIT, notice kept), replacing the old saved-count replay, which could not grade a reply. - replay_server.py checks the send path offline against the published replies. - The example declares sie-sdk>=0.9.0, the first release with the per-call read timeout run.py uses; the old <0.8 pin could not run it.

153-158: 🩺 Stability & Availability | 🔵 Trivial | 💤 Low valueBound image downloads and write them atomically.
prepare_imagescallshttp_getwith nomax_bytes, so an image download has no size limit.path.write_bytesalso runs in eight threads. If a run is interrupted during a write, the cache keeps a truncated file. The hash check then rejects that file and downloads it again, so the cache recovers. The missing size bound is the more useful fix. Passmax_bytesfrom the manifest'sb64_len(decoded size ≤b64_len * 3 // 4). Write to a temporary file and then callreplace.Proposed fix

Image downloads now stop at 16 MiB and every cache write is atomic, so an interrupted fetch cannot leave a truncated file. A single-document send whose reply is not JSON now exits with a bounded excerpt instead of a traceback.

The fixed limit is appropriate for both sets. My suggested I did not rerun the scoring or dry-run checks. ✏️ Learnings added

Two fetch or run processes sharing a cache could race on one .part name. Each write now uses a unique temporary file in the destination folder and removes it if the write or replace fails.
