# Paper Artifact Manifest

This directory points to the reproducible artifacts for the current paper draft.

**Working title:** When Does Lexical Search Help Late-Interaction Retrieval?

## Canonical Reproduction Entry Points

- Config: `experiments/configs/paper_main.yaml`
- End-to-end runner: `experiments/scripts/run_paper_main.py`
- Table compiler: `experiments/scripts/compile_paper_tables.py`
- Command sheet: `artifacts/paper_main/COMMANDS.md`
- Current result snapshot: `artifacts/paper_main/RESULTS_SNAPSHOT.md`

Run the full main experiment:

```bash
uv sync
uv run python experiments/scripts/prepare_paper_data.py --config experiments/configs/paper_main.yaml
uv run python experiments/scripts/run_paper_main.py --config experiments/configs/paper_main.yaml
```

The runner is resumable: it skips completed BM25, dense, fusion, rerank, and feature outputs unless `--force` is passed.

## Current Completed Outputs Used For Analysis

The currently completed experiment outputs live under the historical experiment id `paper8_chunked`:

- Main analysis: `results/paper8_chunked/analysis.md`
- Paper table: `results/paper8_chunked/paper_tables.md`
- Paper table JSON: `results/paper8_chunked/paper_tables.json`
- Per-dataset metrics: `results/paper8_chunked/<dataset>/*.json`
- TREC run files: `runs/paper8_chunked/<dataset>/*.run`

The canonical `paper_main.yaml` includes the 7 datasets with complete BM25, dense, RRF, BM25-rerank, and RRF-rerank results:

- `scifact`
- `nfcorpus`
- `arguana`
- `scidocs`
- `fiqa`
- `cqadupstack/android`
- `cqadupstack/mathematica`

## Reproducibility Notes

- Raw BEIR data and generated indexes are intentionally not tracked in version control.
- `data/` is recreated by `download_beir.py` for standard BEIR datasets.
- CQADupStack subdomains are exported with `export_hf_cqadupstack_to_beir.py`.
- Runtime depends heavily on hardware. Quality metrics are the intended reproducibility target; local latency should be treated as diagnostic.
- Apple MPS can produce non-finite embeddings for some long/chunked inputs. The reranking script repairs affected rows by CPU re-encoding before scoring.
