ZacharyZhang-NY dff5977ab6 Measure what each retrieval leg is worth before choosing a default
The product fuses a sparse page, a dense vector leg, and a picture leg that
only speaks when the words come back thin. Two of the three are off by
default, and until now no committed artifact said why.

bench/leg_check.py asks the frozen suite's 300 answerable queries as their
own holder, once per configuration, and prints recall, first-hit quality,
latency and per-modality recall in one table. The picture index and the
CLIP snapshot are 48 minutes of encoding, so they are carried in rather
than rebuilt per row; the harness refuses to run a leg whose snapshot is
missing instead of quietly scoring nothing.

The numbers that came back:
- words only, 10 atoms: recall@10 0.832, MRR 0.683, p50 64ms
- words only, the configured 24: 0.848, 0.688, 69ms
- words only, page 30: 0.855, 0.690, 67ms
- dense leg on: 0.845 / 0.858, MRR down, p50 469ms / 411ms
- picture leg available: 0.815 / 0.825, MRR 0.553 / 0.551, p50 148ms / 164ms

So both defaults stay off, and the acceptance bar (recall@10 >= 0.90) is
not met by the product path yet: 0.858 is the best measured row, the
in-repo counterpart at holder scope is 0.866. The loss concentrates in
picture golds, and the current CLIP leg pays more in dilution than it
returns there.

CHECKLIST p2-1 and p0-3.7 now quote the committed reports (DENSE.md,
QUANT.md, SCALE.md, TERMS.md) instead of scratch scripts.

bench — the measurement harness

Everything here measures the product as it is. No arm may read a benchmark gold label.

run order

python -m bench.fetch_corpus      # 19 GB of third-party material -> bench/corpus + ~/ely_eye_bench_data
python -m bench.build_sets        # freeze the 6 query sets -> bench/sets/
python -m bench.validate_sets     # schema + gold + scope + modality checks (b-2 gate)
python -m bench.fetch_models      # dense + rerank models used by the ablation arms
python -m bench.ingest_baseline   # the unmodified product ingesting the whole corpus (16 -> 8 workers)
python -m bench.run               # five-arm ablation + latency/scale -> bench/reports/BASELINE.md
python -m pytest bench/tests -q   # metric definitions, hand-computed

bench/runs/ and bench/corpus/ are gitignored; bench/corpus/manifest.jsonl is tracked so the corpus is reproducible from the manifest alone.

the arms (b-3)

arm what it is
bm25_only the product's sparse signal alone
dense_only the product's dense signal alone (product flag is off today)
graph_only the product's graph signal alone — atom.relations is never populated, so it is a constant
no_rerank the product's exact 0.55 / 0.35 / 0.10 fusion
fusion_rerank the same fusion plus a cross-encoder rerank, the upper bound of the current design

python -m bench.run also drives the unmodified RetrievalService.search over the merged database and reports its latency plus how far its top-10 differs from the fast BM25 path.

known environment artifact

pi-lens' pyright reports Import "bench.sets_common" could not be resolved (and the same for bench.metrics, bench.systems, ely_eye.*, cv2, onnxruntime, pypdf.errors) even though every one of those imports works. It is not a repo defect:

  • effective_config on any bench file returns 0 config file(s) with resolvedCwd at the repo root, so neither pyproject.toml [tool.pyright] nor pyrightconfig.json (both of which carry extraPaths: [".", "backend/src"]) is being read by that runner.
  • Runtime proof, run from the repo root with .venv active:
.venv/bin/python -c "import bench.sets_common, bench.metrics, bench.systems, bench.run, bench.ingest_baseline, \
bench.build_mmlongbench, ely_eye.config, ely_eye.db, cv2, onnxruntime, pypdf.errors; print('runtime proof OK')"

Treat that command as the check of record for import health; treat pyright's type findings (it has caught real defects here: an AtomRunner typo, missing strict=True on zip, dict[str, object] over-narrowing) as separate and worth fixing.

The pi-lens mypy cascade also replays stale findings after a fix: it attributes another file's lines to whichever file was edited last (e.g. bench/fetch_models.py:107: "object" has no attribute "encode", where line 107 of that file is a Path call and the quoted text is from bench/systems.py). The check of record is a fresh-cache run, which has passed on every current file:

rm -rf /tmp/mypycache && .venv/bin/python -m mypy --cache-dir /tmp/mypycache bench/   # Success: no issues found
.venv/bin/python -m ruff check bench/                                                  # All checks passed
.venv/bin/python -m pytest bench/tests -q                                              # all green

corpus facts that constrain the numbers

  • 50,789 sources / 5,308 queries (2,928 answerable, 2,380 unanswerable), all third-party.
  • Video-MME ships mp4s for 129 of 900 videos; the set uses those 129 (387 questions).
  • Video-MME has no temporal gold, so its gold region is the whole video — recorded in the set manifest.
  • ScreenSpot-v2 boxes are [x, y, w, h], verified against 755 image headers (xywh in bounds 1271/1272).
  • CodeSearchNet docstrings appear verbatim inside the code, so the query text is stripped before ingest or BM25 gets a free exact match.
  • The product keys a source by {stem[:48]}_{sha256[:16]}, so identical bytes in two sets collapse to one product source; ingest_report.json reports shared_source_ids.
