# Experiment result registry

Each child directory is an immutable result record. Exact metrics, protocol,
raw console output and caveats live in that directory; this page only routes
readers to the right comparison.

| Result record | Question answered |
|---|---|
| [`easycom_open_stream_vs_causal_prefix_2026-08-19/`](easycom_open_stream_vs_causal_prefix_2026-08-19/README.md) | How prepared-media open-stream and causal-prefix features compare |
| [`easycom_open_stream_8s_vs_20s_2026-08-23/`](easycom_open_stream_8s_vs_20s_2026-08-23/README.md) | Frozen open-stream context-length comparison |

| [`easycom_oracle_information_4ep_2026-09-07/`](easycom_oracle_information_4ep_2026-09-07/README.md) | Causal aggregate/per-person oracle information value and identity-continuity control |

## Interpretation rules

- Do not compare full-timeline and causal-valid metrics without naming the
  protocol.
- A single seed is preliminary even when its absolute improvement is large.
- Framewise mAP is retained for EgoSpeak comparability; it does not prove
  correct floor-entry/yield behavior.
- `G+A+V > G+A` does not prove visual speaker grounding unless correct visual
  alignment also beats wrong-person/time-shift controls.
- Historical transition-auxiliary results concern generic label changes, not
  the new scenario-conditioned wearer entry/yield objective.

## Required contents for a new result record

```text
results/<dataset>_<question>_<date>/
  README.md       # hypothesis, command/config, split, seeds, interpretation
  summary.json    # machine-readable aggregate and provenance
  metrics.csv     # when a tabular comparison exists
  raw_console.txt # optional but recommended
```

Never overwrite a dated record with a new protocol. Create another directory
and link the relationship from both READMEs.
