R43 Wave 14-RRR — Paper 1 split into P1A + P1B; cobaya DESI DR2 w0wa chain in burn-in
Wave 14-UUU: Cobaya DESI DR2 chain on pod ijzftpy3klystt has exited the early-mixing fluctuation phase and entered monotonic descent. R̂−1 trajectory (direct getdist on running chains): 0.8632 (10:38) → 0.8168 (11:09) → 0.8404 (11:46) → 0.7390 (12:13) → 0.7075 (12:40). Outlier fraction 13.6% → 11.6% over the same window — chains have found each other's posterior region. Total accepted 667 → 805 across 4 chains, 25% acceptance, ~14 accepted/chain/hr. Sample throughput is rate-limited by Planck NPIPE CamSpec CAMB calls (~1-3 min/call). Headline parameter values from current samples: w ≈ −0.65, wa ≈ −1.25, w0+wa ≈ −1.87 (deep quintom-B region, phantom-crossing). Updated ETA to R̂−1 < 0.01: ~6-12 h (best case, descent rate holds), 18-30 h (1/√N asymptotic). P1 v2.3.18 PDF + cobaya warm-restart shipped Wave 14-SSS (414e212b) + 14-TTT (6c6e9e56). **Only P1B has active compute pending; P1A/P2/P3/P4 blocked solely on Houston sign-off + clean external R43 round + arXiv submission.**

Currently running

  • Cobaya 4-chain MPI run on RTX A5000 pod ijzftpy3klystt — warm-started with posterior covmat from April-6 quintom chain; DESI DR2 + Planck NPIPE + Pantheon+ + DES-Y5; w0-wa CPL PPF; target R̂−1 < 0.01
  • Autonomous /loop self-pacing every ~25 min — polling pod, will GetDist + update P1B §Structural Tension + recompile when R̂−1 < 0.01
