ops(erp-tune): stage + launch R47 ERP-seat SFT run 5 on pfi-gx10

Run 5 = the dependency-forcing corpus arm: airoboros-3.2 OUT of the 20% slot,
govreport/clean-v1 (496) + qmsum/clean-v1 (97) IN, at run 4's lr 2e-04 with
everything else held. kvasir byte-identical (survivors-r5 = survivors-r4 minus
airoboros plus the two new roots whole). Operator authorized the launch to
infra-ops directly; grant operator-2026-09-07-rnd-run5.

Canonical copies of the config, launcher and survivors builder; runbook
docs/runbooks/gx10-run-05.md. Launch gates all passed (7/7 root shas + shard
hashes, survivor join 8,212 = recipe, holdout disjoint, window_count==1 on all
593 slot rows, realized [mix] slot loss 3.46% vs preregistered 3.4%). 524 steps.
persistent-memory current-state updated: run 5 LAUNCHED + training.

## Current state / in-flight
_As of 2026-09-07 (fleet-ops session). SUPERSEDES the "run 4 is TRAINING" framing lower down:
run 4 is DONE (gated STILL-COUPLED); run 5 is AUTHORIZED but stalled. Live open items:_
run 4 is DONE (gated STILL-COUPLED); run 5 is LAUNCHED and TRAINING (09:05 PDT). Live open items:_
- **⚠ ERP run 5 authorized but NOT running — brokkr sat on it; a full GX10 window wasted
(operator, 2026-09-07).** Operator already gave the third eligibility grant and thought it was
training; brokkr-smithy-dev never built the clean roots / `recipe-r5.json` / launched. GX10 idle
(0% GPU) since the run-4 gate. Raw sources ARE staged (nh3-nas `/volume1/smithy/datasets/raw/{ccdv__govreport-summarization,pszemraj__qmsum-cleaned}`, ~09-06 23:06); clean-v1 derived roots +
`recipe-r5.json` + launch still owed by brokkr. Run 5 = dependency-forcing slot (GovReport+QMSum
replace airoboros; single variable; tests whether long-context-dense data breaks the diversity↔coherence
coupling run 4 left STILL-COUPLED). **FOLLOW-UP: nudge brokkr to build+launch — don't waste the next window.**
- **✅ ERP run 5 LAUNCHED + training on pfi-gx10 (2026-09-07 09:05 PDT, pid 3311780).** Operator
said "yes go, launch run 5" directly to infra-ops (relay caveat on brokkr's third grant
`operator-2026-09-07-rnd-run5` closed in-session, as for run 4). Brokkr delivered the build
(roots on /mnt/smithy 08:13, `recipe-erp-seat-sft-r5.json`, grant); infra-ops staged + launched
it. **524 steps, ~52 s/it → ETA ~16:35 PDT** (~7.5 h). All launch gates passed: 7/7 root shas +
shard hashes, survivor join 8,212 = recipe exactly, holdout disjoint 0 overlap, **window_count
belt-and-suspenders PASS** (govreport 496/496 + qmsum 97/97 all fit_whole), realized `[mix]` slot
loss 3.46% (pred 3.4%) at ctx 0.20 — single variable landed; INERT is a live verdict. Dependency-
forcing slot (GovReport+QMSum replace airoboros); kvasir byte-identical (survivors-r5 = survivors-r4
− airoboros + govreport+qmsum, sha a25169a6). Canonical artifacts committed to eshpfi
`scripts/erp-tune-gx10/` + runbook `docs/runbooks/gx10-run-05.md`. **Completion poller `bhrkre8p4`
armed → on adapter-land, coordinate the base-serve→floor-lock→swap-cue→tuned-serve gate with brokkr
on the cc channel** (he's scaffolded run05-gate/ + committed the 4-cell verdict evaluator).
- **run-4 gate = STILL-COUPLED** (RESULT-run04-gate.md, brokkr-smithy). Corpus dilution kept the
diversity gain, did NOT remove the safety/coherence regression. **Base-abliteration LABEL unresolved —
operator's ruling owed** (recipe says `-heretic`, provenance says stock; telemetry leans STOCK: base
