Program timeline

• Jul 2026Phases 1–2
  v1 prototype (40 experiments, 11 claims) → mechanical re-adjudication revises the record; postmortem published
• Jul 24Phase 3 complete
  320 bare-GPT-4.1 runs: corners everywhere; X1 paraphrase flips the corner same-day
• Jul 24Phase 4 sealed + dispatched
  registry v3 (250 arms) sealed 18:58 UTC, tag phase4-v3-seal anchored 19:04
• Jul 25–27Phase 4 executes
  sentinel alert 5 catches Gemini endpoint drift at a block boundary; freezes + memos; zero contaminated confirmatory spend
• Jul 28Phase 4 closes; Phase 5 sealed + run + closed
  phase4-final · registry v4 + personas + discussion branches sealed pre-dispatch · 1,712 runs · Branch 2 selected · phase5-final
• Jul 29Repository public + Round 1–5 reviews
  public at 14:03 UTC, hashes byte-identical; first external reviews land; zero-call reanalysis queue specified and executed
• Jul 29p13 demoted
  R2 family audit: registered rule had a 12.9% familywise false-fire rate; slope downgraded to suggestive
• Jul 30v10 text freeze
  scientific text frozen, tagged, OpenTimestamps-anchored (Round 8); Explore Science scores it 97/100 (Round 9)
• Jul 30v11 addendum
  Dirichlet–Jeffreys latent-propensity sensitivity: composition dominance becomes prior-dependent
• Jul 30–31v12–v14 candidates
  capsule extended to Phase 3 (4,919 total); dependence audits; three release blockers fixed
• Jul 31Round 14 final pass
  middle-path restorations: wording null, P5-2 prior sweep, Appendix A.2 findings; precision corrections
• Aug 1Final release
