sol-max-v2-record
Complete run record for AgentPTB cell sol-max-v2 — Codex / gpt-5.6-sol @ effort max.
A redo of the sol-max cell from hour 0 on node tb-1, after the original attempt died at
~h16. This one ran the full 100 hours (boot 2026-08-19T19:15:00Z).

The arm submitted an hour-7 checkpoint
Of 36 checkpoints spanning 82 hours, the arm selected one written at h7 — choosing it over
75 further hours of its own training. Its self-reported full-suite numbers:
| harness | suite | episodes | score | 95% CI |
|---|
| submitted | terminal-bench-2 | 89 | 4.49 | [1.76, 10.99] |
| submitted | swe-bench-verified | 500 | 22.40 | [18.96, 26.26] |
| stock-compatible | terminal-bench-2 | 89 | 2.25 | [0.62, 7.83] |
| stock-compatible | swe-bench-verified | 500 | 20.40 | [17.10, 24.15] |
These are the arm's own measurements under its own harness and sample size, and are not
comparable across cells. The controlled cross-cell re-measurement is the sweep in INDEX.
