Summary

  • Replace “Pure bpb” miner docs with live scoring_version4: equal-weight G2 public accuracies → lattice. Bits/token bpb no longer farms emission by default.

Test plan

  • README/scoring page reads correctly on GitHub

Summary by CodeRabbit

  • Scoring
    • Benchmark-mode scores now default to the equal-weight average of available G2 benchmark accuracies.
    • Scores are mapped to the integer scoring scale for consistent results.
    • Bits per token remains available for measurement but no longer affects default benchmark scoring.
    • Added shadow scoring for bits-per-byte evaluation and composite scoring across the full scale.
  • Documentation
    • Updated competition guidance to reference the best training score.
    • Clarified when top-model publication occurs.

Review Change Stack

📝 Walkthrough

Walkthrough

The scoring documentation now describes equal-weight G2 benchmark scoring as the default. It retains bits/token as telemetry, documents shadow and composite modes, and changes competition and publication terminology to use scored runs.

Changes

Scoring Documentation

Layer / File(s)Summary
Scoring rules and publication semantics
docs/scoring.md
The documentation defines default equal-weight G2 scoring, shadow bpb scoring, and composite lattice scoring. It updates competition wording and top-model publication triggers to use the best-scored trainer and global-best scored run.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk:🟡 Moderate · up to 77f7a

The scoring documentation changes leave other project documents describing the previous bpb-based scoring and publication rules, which could mislead users and trainers. Merge should wait until the documentation is synchronized or a single source of truth is clearly established.

## Live leaf: G2 benchmarks (`scoring_version` 4)

`final_score = score_from_bpb(measured_bpb)` on the integer lattice `[0, SCORE_MAX]` —
lower bpb, higher score. The LLM reviews are **gates, not graders**: they verify the
submission is coherent and not cheating; their quality notes never move the score.
Leaf score = **equal-weight mean of available G2 public accuracies**
(HellaSwag, ARC-Easy, ARC-Challenge, PIQA, WinoGrande, BoolQ, LAMBADA,
OpenBookQA when present) mapped to `round(SCORE_MAX × mean)` on the integer
lattice `[0, SCORE_MAX]`.

Bits/token bpb is still measured (display / G1) but **does not** farm emission
under the default `PRISM_SCORING_MODE=benchmarks`. Tokenizer length cannot
game the rank. LLM reviews remain **gates, not graders**.

Legacy: `PRISM_SCORING_MODE=shadow` restores pure bits/token bpb (v2);
`composite` uses the full G1–G8 lattice when anchors are ready.

Synchronize the scoring and publication documentation before merge.

docs/scoring.md now defines benchmark scoring, best-scored competition, and scored-run publication. However, docs/prism.md:187-213 still states that scoring is pure bpb and that the best-BPB trainer keeps Prism’s weights. top-model/README.md:1-4 still says publication occurs after a new global-best bpb.

Update these documents in the same change, or clearly designate docs/scoring.md as the sole source of truth and remove the stale statements. Otherwise, users can apply conflicting scoring, emission, and publication rules.

Also applies to: 46-51, 60-65
