 ## Recent decisions
 
+- `[2026-09-11]` **Beszel priority 1: all six installed; Synology hub verification pending.** Vaulted password resolved access; nh3-nas registered with four alerts, but cross-site hub connectivity then timed out. Earlier five verified, 13/13 at that point. → `persistent-memory.d/2026-09-11-beszel-priority1.md`

 - `[2026-09-11]` **Sentinel-R3 pulled, MTP-grafted, and quantized as a M.O.G.-SEC seat candidate — quant DONE, acceptance UNVERIFIED (blocked on GPU space).** Operator got access to `glyphsoftware/sentinel-r3` and asked to compare vs the running M.O.G.-SEC seat + pull if promising, then "quant it with a grafted mtp head". **It is promising and a better FIT**: same base (stock Qwen3.8-27B), same `qwen3_5` hybrid arch, same 262K, vision-intact — but M.O.G.-SEC is a persona on stock weights while Sentinel-R3 is a REAL SFT finetune on 1,230 authorized-pentest agent trajectories over a 19-tool surface that **matches our own harness** (Bash/Read/Write/Edit/Grep/Glob/Agent/Task*/Monitor/…). Card is unusually honest (flags its own mmlu-cybersec 0.88 as within-noise of base). **HF check: M.O.G.-SEC repo unchanged** (sha still our pinned `deede6779…`). **MTP: Sentinel ships ZERO mtp tensors**; grafted the verbatim base head from `qwen38-27b-uncensored-bf16` (compare_mtp_head → IDENTICAL) — lineage correct since Sentinel's base is stock Qwen3.8-27B and that head is a verbatim base graft. ⚠ **Acceptance is UNVERIFIED and may differ from the 47.7% the head hits on STOCK weights** — it now reads hidden states from an SFT-finetuned body (the exact Stage-1b residual risk). Quant = the standard mixed NVFP4-W4A4(MLP 0-55) + FP8-W8A8(attn/linear_attn/lm_head/MLP 56-63) recipe, ran CUDA_VISIBLE_DEVICES=1 on GPU1 free space, no seat downtime, 51→22 GB. post_quant carried the head forward + re-injected `re:^mtp.*` (llm-compressor prunes it → the 0%-accept bug). Structural verify clean: 1968 tensors, 0 unresolved, 15 mtp, 333 visual, ignore has mtp+visual. **Artifact `/tank/aimodels/sentinel-r3-nvfp4-mixed` (+ `.PROVENANCE.txt`).** ⚠ **License is PROPRIETARY** (Glyph Proprietary v1.0, all-rights-reserved) — operator's fair-use/licensee call, not apache like M.O.G.-SEC. ⚠ **Serving/A-B is BLOCKED on GPU space**: weights are 22 GB, GPU0 has 7.6 free / GPU1 19.9 — a probe serve needs a freed co-tenant slot (~25 GB), which is a material-consequence call. Serve with the PROSE system prompt (trained on prose tools, not structured `tools=`). → `/tank/aimodels/sentinel-r3-nvfp4-mixed.PROVENANCE.txt`
 - `[2026-09-11]` ⭐ **MEASURED: two concurrent training jobs on pfi-gx10 are 13% NET SLOWER than running them back to back — VRAM is not the constraint and never was.** Operator asked to run the two BabyYarros arms in parallel if VRAM allowed. It does, comfortably: **18.4 GiB per 4B LoRA job, 36 of 121 GiB with both up, 98 GiB free.** But the GB10 is a *capacity* box, not a throughput box, and the binding constraint is memory bandwidth. Solo baseline **37.10 s/it (n=6, 0.05% spread)**; with a second job both arms settled at **~85 s/it — 2.29x each**, so combined throughput 0.0235 vs 0.0270 steps/s solo. Not a clean 2x split: the box is *past* its roofline and pays a contention penalty on top. ⭐ **Control: killing the second job returned the first to 37 s/it on the very next step**, so the slowdown tracked contention and reversed with it. Chaining finished both arms ~43 min earlier than concurrency would have. **General form: on this box, `nvidia-smi` free memory tells you nothing about whether a second job is affordable.** Decision rule was pre-registered before the numbers were read (<55 s/it keep both, ≥2x chain). `scripts/yarros-corpus/{launch-yarros-4b-base,chain-yarros-4b-base}.sh`; the shared-GPU bypass is an explicit argument, never a default.
+- `[2026-09-11]` ⭐⭐ **BabyYarros COMPLETE — both arms trained AND evaluated; the voice moved toward Yarros above the measured noise floor, and the instruct arm renders beats 9/10.** Training: **Base best held-out 2.5263 @ ckpt-125** (overfits within the epoch — best is the checkpoint, not the shipped step-178 adapter), **Instruct 2.6114 @ 178** (still descending, undertrained if anything). Base-wins-held-out / Instruct-holds-instruction replicates Brontë at a near-identical **0.085-nat** gap. **Eval (gx10, seat-free, done during the Anaheim outage):** three voice arms + instruct beat→paragraph. `delta_cb` (Burrows over char-bigrams vs held-out Yarros) ordering **base-125 0.549 < instruct 0.631 < base-unadapted 0.706**, same-author target 0.463; both adapters clear the **0.046 measured noise floor** (within-arm seed spread, not the same-author distance — first cut mis-framed that) — base **+0.157**, instruct **+0.076** vs control. ⚠ One seed-pair per arm, so the ordering CORROBORATES the independent held-out-loss ordering rather than settling it. **Beats (instruct, chat template, Yarros SYS): on-beat 9/10** (it takes direction after raw-text training — the Skaldsong question, answered yes), in-band 5/10, ran-on 7/10 (length + clean-close discipline is the weak axis, same trade as Brontë). Booth: **http://10.100.10.50:8090/b/babyyarros-voice/**. Tooling `scripts/r49-corpus/{voice_prompts_yarros.json,gen_beats_chat_yarros.py,voice_distance.py,build_booth_yarros.py}`, commit `5558d9c`. ⛔ **DEFERRED to power-return** (needs the ana-ml2 gen seat): the frozen adjudication's romantasy control panel, a 2nd seed, and the beat-incumbent leg.
 - `[2026-09-11]` ⭐⭐ **BabyYarros UNBLOCKED and TRAINING: the leak gate passes at 0 of 325 entities and 0 of 91 phrases, and closing it turned up three defects nobody was looking for.** The gate itself is the first artifact — there was no committed instrument for "does any of the author's proper nouns survive", so Brontë's 0-of-203 was a hand count. `scripts/r49-corpus/leak_gate.py` now runs the same scan over the UNRENAMED source as a **positive control** plus a nonce **negative control** every time, because a detector that only ever sees renamed text cannot tell *absent* from *blind*. Its first reading was **212 surviving, not 86** — it scans the whole corpus rather than per work, and counts the sub-threshold entities rename never looked at. Training launched 10:06 PT on pfi-gx10: Qwen3-4B-**Instruct**, 1 epoch, seed 4919, 178 steps / 5,824,512 tokens, corpus sha `e85f69f1e49d57c9`. → `persistent-memory.d/2026-09-11-babyyarros-leak-gate-passes.md`
 - `[2026-09-11]` ⭐⭐ **A SECOND corpus typography defect, and the D1 note that "no unwrap was needed" was right about the wrong thing.** Kvasir's cleaner does emit flowing paragraphs, so Brontë's hard-wrap defect genuinely does not exist here. A *different* one does: the Empyrean books set chapter epigraphs in small caps and the extractor rendered the run as uppercase while leaving the large initial its own token — `— M AJOR A FENDRA'S G UIDE TO THE R IDERS Q UADRANT (U NAUTHORIZED E DITION)`, **106 lines / ~700 splits**, plus **52 drop caps** (`T he flight field`, `X aden.`, 51 of 52 in iron-flame). That is the entire source of the entities called `IDERS`, `UADRANT`, `NAUTHORIZED`, `DITION` and seventeen bare single letters. ⭐ **The restore is exact, not approximate**: a split initial next to an uppercased run recovers the original mixed case, because a word WITH a split initial was capitalised in the source and an all-caps word WITHOUT one was lowercase. ⚠ Guards that matter: only lines with **≥2** splits are treated as a run (one split is a sentence next to an acronym), and `I`/`A`/`O` are excluded from the drop-cap join or `A slow smile` becomes `Aslow`. `scripts/yarros-corpus/repair_typography.py`.
 - `[2026-09-11]` ⚠⚠ **Back matter was inside the prose of all five works — 4,555 words naming the author's agent, editors and children.** The builder splits on chapter headings and nothing follows the last one, so acknowledgments, newsletter pitches and cover-artist credits rode inside the final chapter. Found by the gate's phrase audit surfacing `Louise Fury` (Yarros's literary agent), not by reading. ⚠ **iron-flame's marker is `ACKNOWLEDGMENTS` in all caps** and a case-sensitive scan missed it — the strip is case-insensitive and last-chapter-only, with an acceptance check that refuses if it would remove more than 2% of the corpus.
