# ERP run 7 launched on pfi-gx10 (2026-09-08 23:06 PT)

Operator's direct grant `operator-2026-09-08-rnd-run7` (in-session `/goal: launch training run 7 on gx10`, 23:03 PT), pid 599489, 542 steps, ~80 s/it, ETA ~noon 09-09. Runbook `docs/runbooks/gx10-run-07.md`; canonical `scripts/erp-tune-gx10/{run-07-gx10.json,launch-run-07.sh,build_r7.py}`; commits `a34a72f`, `d8f625e`.

- Variable (brokkr `recipe-erp-seat-sft-r7.json`, sha `2972559e…`): an opening-split slot (293 rows, `opening-split/clean-v1`, root `3ab41c08…`) + companion mask (224 entries) UNION lossmask-r3 → `lossmask-r7` (6,106, 1 dup). `survivors-r7` = survivors-r5 + 293 = 8,505. Root/mask/holdout relayed NAS→nh3-dev→box (no NFS on the GX10), sha-verified.
- Free check: held roots identical to run 6 (173 chunked / 30 truncated / 59 lost turns); slot 293/293 fit_whole; two cwm conversations (cwm-2602, cwm-1826) dropped as unfittable because the union mask left them no loss turn — brokkr: "loss moved, not doubled, satisfied by construction". Padding 17.1% (run 6: 0%).
- ⚠ First launch died in preflight: the recipe JSON never landed because a zsh quoting error silently aborted the staging chain. Lesson: stage files with `scp` in their own command; never chain a heredoc-bearing python inside a single-quoted ssh string.
- Gate after the adapter: brokkr commits `tools/base_window_r7.sh`, `tools/tuned_window_r7.sh`, `tools/verdict_run07.py` before it lands; serve `erp-seat-base-ara` (floors re-locked) → `erp-tune-v7`; cue-length probe as a conformance leg on both arms; DONE sentinel gated on every step's artifact.
