fix(prism): fair review for generic LM tropes

[echobt]

Summary

• Prod rejects for 6d0824f9… / b19998da… were cheap LLM similarity-v2 false positives (RMSNorm/RoPE/SwiGLU evidence at score 0.7), not AST copy-gate or agentic. AST vs peers/baseline is ~6100–7400 bps (under AST_SUSPICIOUS_BPS=8500).
• similarity-v3 + parser coercion: generic modern-LM components are never plagiarism evidence; pre-pod hard-rejects Copied only (Suspicious advisory).
• Copy / LLM similarity / agentic corpus = champions only (Score>0 tops + ex-tops) + baseline.
• Public site gallery/leaderboard hide non-champions; operator challenge API still lists all.
• Prod ops: reopened prism gating to open for both miner hotkeys (no scores invented).

Test plan

• cargo test -p prism-review -p prism-challenge -p site-data -p site-api -p challenge-agentic -p prism-store -p prism-pipeline
• CI green
• Deploy prism-challenge + gateway (site filter); confirm precheck still works
• Miners can submit again under same hotkeys

Summary by CodeRabbit

• New Features

  • Public Prism galleries and leaderboards now show only current and historical champion submissions with positive scores.
  • Similarity reviews use champion architectures and baseline references while excluding standard language-model components as plagiarism evidence.

• Bug Fixes

  • Suspicious similarity findings are now advisory instead of automatically producing a zero score.
  • Clear copying and agentic cheating or suspicious behavior continue to trigger hard-zero scoring.
  • Generic architecture terminology is no longer treated as sufficient evidence of copying.

• Documentation

  • Updated Prism scoring, review, corpus, and public API guidance to reflect these changes.

📝 Walkthrough

Walkthrough

PRISM now limits copy and review corpora to positive-score champion submissions, updates similarity review to v3, ignores generic language-model components as plagiarism evidence, makes suspicious similarity advisory, and exposes champions only in public listings.

Changes

PRISM review and champion filtering

Layer / File(s)	Summary
Champion corpus retrieval and wiring crates/prism-store/..., crates/db/..., crates/prism-challenge/..., crates/prism-pipeline/...	The store adds champion listing support. Copy, agentic, and similarity flows use champion submissions instead of general or terminated submissions.
Similarity prompt and generic-architecture handling crates/prism-review/prompts/similarity_v3.md, crates/prism-review/src/..., docs/COMPLETENESS.md, docs/PRISM_RECIPE.md	Similarity v3 defines architecture-only judgments. Generic language-model evidence is coerced to Original under the defined confidence thresholds.
Scoring and anti-cheat verdict handling crates/challenge-agentic/..., crates/prism-challenge/..., docs/PRISM.md, docs/external-miner/prism.md	Only Copied similarity results hard-gate scoring. Agentic Cheat and Suspicious results remain hard-zero outcomes.
Public champion filtering crates/site-data/..., crates/site-api/..., docs/SITE_API.md	Public Prism submissions and BPB leaderboard entries now include positive-score champion submissions only.

Estimated code review effort: 4 (Complex) | ~45 minutes
