# `[2026-09-08]` ERP-seat SFT run 5 — gate = RESCUED (landmark R49.5)
|
||
|
||
The FIRST arm of the R47 ERP-seat line where the capability gate did NOT fail.
|
||
Operator launched it directly to infra-ops ("yes go, launch run 5", the relayed
|
||
grant `operator-2026-09-07-rnd-run5` closed in-session per the no-relayed-auth
|
||
rule). Brokkr built the corpus; infra-ops staged + launched + served the gate.
|
||
|
||
## The result
|
||
|
||
- **RESCUED.** Structure of the loss was the lever, not its mass: the
|
||
dependency-forcing slot (GovReport 496 + QMSum 97, only **3.46% of loss** at
|
||
20% ctx) broke the diversity↔coherence coupling that run 4 (STILL-COUPLED,
|
||
20.6% instruct slot) and 3c (20× LR cut) could not. **INERT did not fire.**
|
||
- Mechanism: **T4 long-context 8/8** (run 4: 5/8; base 8/8); t4_dissect noise@31
|
||
tuned **0.9062** vs run-3 tuned 0.5625; diversity held (rp density 3.37→0.00,
|
||
story 2.86→1.58).
|
||
- Reported-beside (not in the cell, de-gated + stated): T3 constraint 8/8→**6/8**
|
||
(a NEW loss, ship-path list); RP length 68w vs the 250-floor = **PARTIAL fail**
|
||
(short-QA slot + style shift); refusal erosion rides with the style shift (k=25
|
||
both arms, CSAM clean, benign 99/100); free-check base LEVELS 5–6pp below run 4
|
||
on identical bytes/stack (a generations shift, vLLM 0.28.0 unchanged — infra
|
||
confirmed; taxes every cross-run number).
|
||
- Write-up: brokkr-smithy `research/R47-premium-corpus-gate/run05-gate/RESULT-run05-gate.md`;
|
||
`FLOOR-LOCKED 0f3e4e2` cites infra-ops' base index-sha 907826a6.
|
||
|
||
## The run (infra side)
|
||
|
||
- pfi-gx10 (GB10, sm_121, aarch64), 524 steps / 1 epoch / ~11.8 h / 81 s/it,
|
||
train_loss 3.235; adapter verified (410 tensors). Launch gates all passed:
|
||
7/7 root shas + shard hashes, survivor join 8,212 = recipe, holdout disjoint,
|
||
**window_count belt-and-suspenders** (govreport 496/496 + qmsum 97/97 fit_whole),
|
||
realized `[mix]` slot loss 3.46% (pred 3.4%). `provenance.json` carried the
|
||
override id + both blockers + all substitute controls.
|
||
- Gate served on gx10:8098, base→tuned, name-keyed swap, hands-off honoured; base
|
||
sha + vLLM-stack answers on the record before Brokkr needed them.
|
||
- Canonical: eshpfi `scripts/erp-tune-gx10/` (run-05-gx10.json, launch-run-05.sh,
|
||
build_r5_survivors.py) + `docs/runbooks/gx10-run-05.md`. survivors-r5 =
|
||
survivors-r4 − airoboros + govreport+qmsum whole (kvasir held byte-identical),
|
||
sha a25169a6.
|
||
|
||
## Seat + open decision
|
||
|
||
`erp-tune-v5` served on gx10:8098 (merged-run05); LiteLLM `trial` alias repointed
|
||
3c→v5 (operator 2026-09-08) — verified end-to-end. Seat is hand-launched
|
||
(`vllm-run05.pid`, no systemd) — dies on a gx10 reboot, yields to next training
|
||
(~6 min re-serve). **OPEN (operator + brokkr): accept RESCUED-on-stock, or source
|
||
a bf16 abliteration + re-run** — now evidenced, see [[2026-09-08-base-provenance-stock]].
