What changed

examples/doc-field-extraction-omni now carries the recipe that was actually measured for superlinked.com/doc-field-extraction, and it can grade replies instead of replaying saved counts.

  • run.py builds the measured request: SYSTEM + "\n\nJSON schema:\n" + json.dumps(schema, indent=2) as the system message, one image, a strict json_schema response_format in which every leaf is nullable, temperature 0, presence_penalty 0 and max_completion_tokens 8192. It sends one document (--image --schema) or a whole published set (--set pilot|confirm) to any SIE endpoint through sie_sdk.SIEClient: a local server, a remote self-hosted one or SIE Cloud. --dry-run rebuilds the requests offline and checks them against 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 Python port of OmniAI's benchmark src/evaluation/json.ts (MIT) and json-diff 1.0.6 (MIT). The MIT notice is kept at the top of the file. The old saved-count replay is removed. Nothing in this repository references it, and the site links to the pinned 971f2d4 tree.
  • replay_server.py stands in for /v1/chat/completions so the SIEClient send path can be checked without a GPU.
  • pyproject.toml/uv.lock follow the other examples and declare sie-sdk>=0.9.0 (locked 0.9.0) and Pillow 12.2.0.
  • The README gives the measured results with links to the evidence, the conditions they were measured on (not requirements), and how to run against a self-hosted server or SIE Cloud.

Why

  • The schema never reached the model. The previous example sent the schema only as response_format. SIE applies response_format purely as a decoding grammar, so the model never saw the field descriptions. That recipe scored 75.64 on the 546 confirmation documents.
  • The corrected recipe scored 91.03 (95% CI 89.75 to 92.20) on 546 fresh Omni documents. It was non-inferior to GPT-6 Luna (90.11) in the pre-registered test: margin 3 points, lower bound -0.51. Superiority over Luna was not shown, and GPT-6 Sol scored higher, at 94.70.
  • The old score.py could not grade a reply. It only re-added saved per-document counts.
  • The old run.py failed under its own pin. It pinned sie-sdk>=0.7.3,<0.8 but used read_timeout_s, which first shipped in 0.9.0.

Verification

All checks ran offline. There were no model calls, and nothing was downloaded except the pinned public files.

  • python3 run.py --set confirm --dry-run: the bodies hash to 8e796736eac72b18e0815a6c62e265c29e154768ced92006140aad50802010d8, the published A1.confirm.bodies.jsonl.sha256. The readable bodies are byte-identical to the published A1.confirm.bodies.show.jsonl. All 546 images matched the published manifest.
  • uv run run.py --set pilot --dry-run (Pillow 12.2.0), from a fresh download: the bodies hash to d364ac86… and the readable form is byte-identical to the published A1.bodies.show.jsonl.
  • python3 score.py --set confirm --published: mean 91.03, and all 546 per-document records match the published omni_scores.json.
  • python3 score.py --set pilot --published: mean 90.15, and all 100 records match.
  • uv run run.py --set {confirm,pilot} --base-url pointed at replay_server.py (sie-sdk 0.9.0): 546 of 546 and 100 of 100 wire bodies matched the published bodies. replies.jsonl was byte-identical to the published A1.jsonl, and the runs scored 91.03 and 90.15. A single-document send matched its published body too.
  • In the example folder, ruff check and ruff format --check (ruff 0.16) passed, and so did uv lock --check. The root uv lock --check is unaffected, because examples are not workspace members.

Evidence

Summary by CodeRabbit

  • New Features
    • Added an example workflow for extracting document fields from images using a schema, with options to process a single image or rerun a full study against a configured endpoint.
    • Added tools to download study data, score extraction results, compare scores with published results, and replay published responses offline without a GPU.
    • Documented pilot and confirmation study results, reproduction steps, and output formats.
  • Bug Fixes
    • Added verification for downloaded study data and image integrity, with retries for temporary network failures.

…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 value

Bound image downloads and write them atomically.

prepare_images calls http_get with no max_bytes, so an image download has no size limit. path.write_bytes also 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. Pass max_bytes from the manifest's b64_len (decoded size ≤ b64_len * 3 // 4). Write to a temporary file and then call replace.

Proposed fix
-            data = http_get(f"{PINS['omni']['base_url']}/{name}")
+            data = http_get(f"{PINS['omni']['base_url']}/{name}", max_bytes=row["b64_len"] * 3 // 4 + 4)
             if sha256(data) != source_sha:
                 raise SystemExit(f"{doc_id}: downloaded {name} does not match its pinned sha256")
-            path.write_bytes(data)
+            tmp = path.with_suffix(path.suffix + ".part")
+            tmp.write_bytes(data)
+            tmp.replace(path)

b64_len describes the image that was sent. For omni-407, the source PNG is larger than the derived JPEG. Skip the size bound when spec is set.

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.

@coderabbitai Both findings are addressed in 3416a1c.

  • run.py non-JSON reply: fixed as suggested. The reply is in the inline thread.
  • fetch.py image downloads: image downloads now pass max_bytes, and every cache write (pinned files, downloaded images and the derived page) goes through write_atomic, which writes a .part file and then calls replace. The bound is a fixed 16 MiB rather than one derived from b64_len. Only the pilot manifest has b64_len; the confirmation manifest does not, so the suggested expression would raise KeyError there. The largest pinned source is 4.3 MB, and each file is still checked against its pinned sha256.

Re-verified offline after the change. A fresh pilot fetch left no .part files. score.py --published gives 91.03 (546 of 546 documents identical) and 90.15 (100 of 100). The confirmation dry-run bodies still hash to 8e796736….

@svonava Thanks for the fixes and the manifest clarification. I inspected the code and confirmed both fixes:

  • run.py catches non-JSON replies and reports an excerpt limited to 500 characters.
  • fetch.py limits image downloads to 16 MiB, retains SHA-256 checks, and uses write_atomic for pinned files, downloaded images, and the derived page.

The fixed limit is appropriate for both sets. My suggested b64_len expression would fail on the confirmation manifest.

I did not rerun the scoring or dry-run checks.

Learning: In examples/doc-field-extraction-omni, only sets/pilot.image_manifest.json includes b64_len; sets/confirm.image_manifest.json does not. Do not derive download limits from b64_len for both sets. fetch.py uses a fixed 16 MiB image-download limit and verifies downloaded images against pinned SHA-256 values.

Note: Learnings are effective only in the context of similar code segments. To apply general coding guidelines, please configure review instructions. You can manage existing learnings in the app.

You are interacting with an AI system.

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.
