memory: snapshot — run 3 gated DO-NOT-SERVE, run 3c held on a tripped breaker
Run 3 trained, gated and dispositioned do-not-serve on a measured 44pp self-harm guardrail regression that its own preregistered rule passed -- a pooled preserve-list test cannot see a single-axis collapse. Run 3c (lr 20x cut, single variable) launched, killed by an Anaheim power-breaker trip at step 80, relaunched, then stopped by the operator at step 22 pending a weekend power triage. Also captured: the corpus mix was specified in a unit the optimiser never sees (45.8% dialogue by context, 24.2% by loss); the dose-response says benefit and damage are one direction in weight space, so the merge-back measures the problem rather than fixing it; four guests including the storage SPOF had onboot unset and never came back from the outage, now fixed with dependency ordering; and a transport failure that enters a measurement as a value looks like whatever you hoped to find -- which found a live defect in another agent's instrument an hour after it was reported.

# eRP dual-seat overhaul — MeroMero-v2 + Dark-Scarlett, NVFP4A16 @ 256K on ana-ml2
|
||||
|
||||
`[2026-08-12]` Replaced the two legacy char-rp seats with home-quantized NVFP4A16 vLLM
|
||||
seats. Operator-driven, end to end this session.
|
||||
|
||||
## What landed
|
||||
|
||||
| Seat (LiteLLM alias) | Model | Role | GPU | Context |
|
||||
|---|---|---|---|---|
|
||||
| `char-rp` (:8016) | **G4-MeroMero-v2-31B** (Gemma-4) | non-thinking PROSE, **multimodal (vision)** | GPU0 | 256K @ 2.07× (util 0.52) |
|
||||
| `char-rp-reasoning` (:8018) | **Dark-Scarlett-v1.0-27B** (Qwen3.6) | THINKING (default) | GPU1 | 256K @ 1.62× (util 0.44) |
|
||||
|
||||
- Both **NVFP4A16 weight-only** (llm-compressor, `compressed-tensors`), `--kv-cache-dtype fp8`.
|
||||
- Replace: `char-rp-gguf` (Magidonia-24B GGUF/llama.cpp, :8016) + `heretic2-charrp-reasoning`
|
||||
(DavidAU Qwen3.6-27B-Heretic2 modelopt NVFP4+MTP, :8018). Old stacks/containers **stopped +
|
||||
retained** for rollback.
|
||||
- Compose-ified: `stacks/meromero-charrp` + `stacks/darkscarlett-charrp-reasoning` (ana-ml2
|
||||
`/opt/docker/compose/`, mirrored to eshpfi, commit **`f08b6cb`**) → survive reboot.
|
||||
- Research that drove picks: `docs/pfi/erp-thinking-finetunes-2026.md` (from the `gecko-65` Booth).
|
||||
|
||||
## Load-bearing lessons (the whole point of this file)
|
||||
|
||||
1. **Load via the ConditionalGeneration WRAPPER class, never `AutoModelForCausalLM`.** For a
|
||||
multimodal-capable base (Gemma-4, Qwen3.6), `AutoModelForCausalLM.from_pretrained` +
|
||||
`save_pretrained` writes a FLAT text config (`Qwen3_5TextConfig`, `model.layers.*`) that
|
||||
**both vLLM AND SGLang reject** (SGLang: "Qwen3_5ForCausalLM has no SGLang implementation";
|
||||
vLLM wants `Qwen3_5ForConditionalGeneration`). Loading via `Qwen3_5ForConditionalGeneration` /
|
||||
`Gemma4ForConditionalGeneration` keeps the wrapper config they accept. **This was the DS
|
||||
blocker** — re-quant via the wrapper fixed it (`Dark-Scarlett-...-NVFP4A16-wrapper`).
|
||||
2. **NVFP4A16 is weight-only → DATA-FREE.** llm-compressor infers `DataFreePipeline`; calibration
|
||||
data is unused (only matters for W4A4 activation quant). W4A16 chosen per NVIDIA's sm_120
|
||||
long-context guidance (W4A4 KLD 2-4× worse past ~10k ctx).
|
||||
3. **Load on CPU (`device_map=None`)** so llm-compressor onloads one layer at a time. `device_map=
|
||||
"auto"` packs the whole model onto the GPU and OOMs when the card isn't fully free.
|
||||
4. **Both models are KV-EFFICIENT — the "dense = KV-hungry" worry was WRONG.** MeroMero (Gemma-4)
|
||||
uses **sliding-window attention** (most layers cache only a bounded window); DS (Qwen3.6) uses
|
||||
**hybrid GatedDeltaNet linear-attention** (3:1 linear:full, linear layers carry no KV). Both
|
||||
hit full native 256K easily. (MeroMero KV pool ~542K tokens at util 0.52.)
|
||||
5. **MeroMero vision reconstruction.** The finetune ships `processor_config.json` (image_processor
|
||||
inline, `Gemma4ImageProcessor`) but NOT `preprocessor_config.json` — the old-format file vLLM's
|
||||
feature-extractor loader wants. **Even google/gemma-4-31B-it (ungated!) ships only
|
||||
processor_config.json.** FIX: extract the `image_processor` section → write
|
||||
`preprocessor_config.json` verbatim, serve WITHOUT `--language-model-only`. Verified (model
|
||||
correctly ID'd a red circle). Audio is config-declared but WEIGHTLESS (0 audio tensors).
|
||||
6. **GPU placement.** Match the KV-heavier model to the roomier GPU. GPU0 (gen neighbor, ~54GB
|
||||
free) > GPU1 (utility cluster, ~45GB free). Swapped MeroMero→GPU0, DS→GPU1. Pins via compose
|
||||
`deploy.resources.reservations.devices`.
|
||||
|
||||
## Dead ends (tried + abandoned)
|
||||
|
||||
- **DS via llm-compressor `AutoModelForCausalLM`** → flat config vLLM/SGLang reject. → wrapper class.
|
||||
- **DS via NVIDIA ModelOpt** → modelopt↔transformers **version deadlock**: current transformers
|
||||
supports `qwen3_5` but crashes modelopt's sparse-moe plugin (`issubclass()` on a non-class);
|
||||
modelopt 0.43.0 pulls an old transformers that can't load `qwen3_5` at all. Abandoned.
|
||||
- **DS via SGLang** → `Qwen3_5ForCausalLM has no SGLang implementation`. Abandoned, but it REVEALED
|
||||
that both engines need the wrapper (→ the fix in lesson 1).
|
||||
- **`device_map="auto"` for the quant** → CUDA OOM in the weight observer. → `device_map=None`.
|
||||
|
||||
## granite retired + gateway repoint
|
||||
|
||||
- `vllm-granite` (granite-4.1-8b, fleet summarizer, GPU1) **`docker stop`ped** (reversible) to
|
||||
reclaim ~13.6GB GPU1 for RP context.
|
||||
- LiteLLM (`ana-docker:/opt/docker/conf/litellm/config.yaml`, backed up
|
||||
`.bak-pre-granite-down-*`): **`granite-4.1-8b` alias RETIRED** — commented out, now 404s cleanly
|
||||
(the `*` wildcard→llama-swap was decommissioned 2026-06-20, so no fallthrough). **`summarizer` +
|
||||
`classifier` REPOINTED to gen** (`hosted_vllm/qwen3.6-35b-a3b-heretic` @ :8015,
|
||||
`enable_thinking:false`) — both verified. ⚠ This LiteLLM change is **server-only / not
|
||||
version-controlled** (a follow-up).
|
||||
|
||||
## MTP — deferred
|
||||
|
||||
DS's MTP heads were dropped by the CausalLM loader; **deferred, not restored** (spec-decode is
|
||||
net-negative at RP temps: ~38-52% accept at temp 0.8-1.25, below vLLM's 0.5 cutoff). The
|
||||
splice-back path (`splice_mtp.py` in the heretic2 work dir) exists if ever wanted. MeroMero
|
||||
(Gemma-4) has no MTP by architecture.
|
||||
|
||||
## On-disk / where things live
|
||||
|
||||
- Quant pipelines: `ana-ml2:/tank/aimodels/meromero-v2-nvfp4-work/` +
|
||||
`/tank/aimodels/darkscarlett-nvfp4-work/` (scripts, BF16 source, NVFP4 outputs).
|
||||
- Compose stacks: `ana-ml2:/opt/docker/compose/{meromero-charrp,darkscarlett-charrp-reasoning}/`.
|
||||
- Gateway aliases (unchanged, port-based): `char-rp`→:8016, `char-rp-reasoning`→:8018. (char-rp was
|
||||
also fixed from the stale `magidonia-24b-v4.3` backend model name → `char-rp`.)
|
||||
|
||||
## Open follow-ups
|
||||
|
||||
1. LiteLLM granite/repoint change NOT version-controlled (server + backup only).
|
||||
2. eshpfi unpushed (many commits this session incl. `f08b6cb`, `7bd7375`, `398b58a`).
|
||||
3. MTP deferred (see above).
|
||||
4. DS thinks verbosely (~13:1 reasoning:content) — eval item; consumers need generous `max_tokens`.
|
||||
5. MeroMero full 256K needs util 0.55 (GPU0 ~1.8GB free, tight); ran at 0.52 for headroom (~4.6GB).

`[2026-08-11]` **stonehenge-park — new fleet `/park` service repo stood up + designed.**
|
||||
|
||||
**What.** A separate greenfield repo (`~/development/stonehenge-park`, gitea `vh/stonehenge-park`,
|
||||
pushed) for a self-contained `/park` service: one durable place to park any idea (repo-born OR
|
||||
personal), find it by search, and have it **actively resurface** (by due-date or staleness) until
|
||||
acted on — so parked ideas stop dying when a repo goes cold. NOT part of eshpfi; this is a pointer.
|
||||
|
||||
**Design (via `/vor-plan`, converged + persisted to `docs/design/`):** four contract-sized units —
|
||||
**U1** core store+API (SQLite+FTS5, slug minting, bearer auth, REST) — the tracer, build first; **U2**
|
||||
scheduler+notifier (in-process; due/stale → statusline `due-count` + althing push to a dedicated
|
||||
**assistant channel**; keep-surfacing until promote/drop/re-snooze); **U3** `park` CLI (mirrors the
|

`secret` CLI); **U4** browse UI. `/vor-ui` ran too (U4 brief persisted).
|

|

**Locked decisions (operator):** SQLite, self-contained, ONE container, no external DB ("don't want
|

title-derived slugs + short ID (addressable as `park/<slug>`); active keep-surfacing resurfacing with

**re-snooze as the anti-nag valve**; bearer key, LAN/WG-internal; host nh3-docker; `/park` **replaces**

only the v1 target) as a **fast-follow after v1** incl. migrating existing lots.

**Deferred (in the plan):** the althing assistant-channel handle **name** (decide at U2 contract

New repo `~/development/tts-stack` (commit `9ee3288`) carries: dots-tts stack (canonical intent), `voices/` corpus (MOVED out of eshpfi), `KNOWLEDGE.md` (engine landscape + prosody findings + foot-guns), `docs/infrastructure.md` (irv-ml1 access + gated deploy runbook + rollback), CLAUDE/persistent-memory/ROADMAP, `tools/` (pause-probe + Booth render). Followed the **chatterbox-fast precedent**: eshpfi `stacks/dots-tts/` reduced to a POINTER README; the ~15 experimental TTS compose wrappers stay here as reference (catalogued in tts-stack KNOWLEDGE). Blast-radius check: no eshpfi playbook/script reads the canonical corpus (other `voices/` refs = unrelated host paths). **Reverses** the earlier "Corpus home = eshpfi `voices/` (keep-here)" call. ⚠ tts-stack is LOCAL-ONLY until pushed — needs a gitea remote (`vh/tts-stack`) + push before the separate agent can clone (operator's call — outward-facing + repo-create creds).

- `[2026-08-10]` **dots-tts v3 — clause-break → period pause mapping.** Operator: v2 "sounds good" but donut won't pause at semicolons/dashes. ROOT CAUSE (measured via a pause-probe A/B — synth duration over N runs, non-determinism averaged out): dots' prosody honors a real pause **only for ellipsis (~+0.43s) and period (~+0.3s, capitalization-independent)**; comma/semicolon/colon/dash all run **flat (~+0.03s vs no-punct)**. Two distinct sub-causes: **dashes regressed in v2** (the `—`→`-` fold made em-dashes read as word-joiners), while **semicolons were NEVER a v2 change** — dots ignores them natively, only newly noticeable because v2 made everything else clean. Operator call: ellipsis "too much" → **map `;`, clause `:`, and em-dash `—` → period** in `_sanitize` (believable ~0.3s clause break). GUARDS (pinned by 11 unit tests, `stacks/dots-tts/test_sanitize.py`): digit-guarded colon `(?<!\d)\s*:\s*(?!\d)` so times `3:45` / ratios `2:1` survive; en-dash `–`→hyphen KEPT (numeric-range `10–20` safety — em-dash breaks, en-dash ranges, different jobs); genuine ellipsis left at full strength (author meant a long pause). Gated deploy (redeploy2 pattern → v3): build → throwaway :8199 test container + **pause-gate** (semicolon sentence must run ≥0.12s longer than baseline; measured **+0.427s**) → only then cut live over.

ROOT CAUSE (isolated via A/B booth): **curly/typographic apostrophes** (`’` U+2019 from ratatoskr's LLM) — dots' tokenizer mispronounces them; STRAIGHT apostrophes read clean under `normalize_text=True`. FIX (`app.py`): fold curly→ASCII (`str.maketrans`) before synth, **KEEP `normalize_text=True`** (operator call — retains number/date expansion). Also added **server-side sentence-chunking** (pack ≤280 chars): dots caps one `generate()` at ~500 patches/~40s, so long RP turns (the Zev monologue = 160s audio) truncated; chunking stitches them (verified full 160.3s, not 40s-cut). **⚠ BUILD FOOT-GUNS (both bit this redeploy):** (1) upstream dots.tts `constraints/recommended.txt` now pins **`gradio==6.17.0` — phantom, not on PyPI** → fresh `pip install dots.tts` unsatisfiable; FIX = pin `dots.tts==0.2.1` + **DROP** the `-c recommended.txt` constraints (0.2.1 pulls working gradio 6.17.3). (2) pinning only `torch==2.8.0` let **torchaudio float to 2.11.0 → dots.tts refuses to load** (minor-version match check); FIX = pin `torchaudio==2.8.0`. **⚠ DEPLOY LESSON:** `docker compose up -d` to a new tag swaps the LIVE container BEFORE any health check — a broken image crash-loops production (**ratatoskr TTS down ~1-2min this session**). NEW PATTERN = build → test in a THROWAWAY container on an alt port (:8199) → health+verify → only THEN cut live over (redeploy2.sh). v2 LIVE + healthy on irv-ml1:8198, **CONSUMER-CONFIRMED clean** (ratatoskr verified end-to-end on their :8765 — apostrophe string reads clean, /api/tts 200 @ 48kHz, no client change; the ~1-2min blip didn't hit them, their concurrent auto-audio issue was client-side localStorage). **rollback = `sed DOTS_TAG=v1 + docker compose up -d dots-tts`** (v1 image retained).

# eRP dual-seat overhaul — MeroMero-v2 + Dark-Scarlett, NVFP4A16 @ 256K on ana-ml2
|
||||
|
||||
`[2026-08-12]` Replaced the two legacy char-rp seats with home-quantized NVFP4A16 vLLM
|
||||
seats. Operator-driven, end to end this session.
|
||||
|
||||
## What landed
|
||||
|
||||
| Seat (LiteLLM alias) | Model | Role | GPU | Context |
|
||||
|---|---|---|---|---|
|
||||
| `char-rp` (:8016) | **G4-MeroMero-v2-31B** (Gemma-4) | non-thinking PROSE, **multimodal (vision)** | GPU0 | 256K @ 2.07× (util 0.52) |

|
||||
|
||||
- Both **NVFP4A16 weight-only** (llm-compressor, `compressed-tensors`), `--kv-cache-dtype fp8`.

|

- Research that drove picks: `docs/pfi/erp-thinking-finetunes-2026.md` (from the `gecko-65` Booth).
|
||||
|
||||
## Load-bearing lessons (the whole point of this file)
|
||||
|
||||
1. **Load via the ConditionalGeneration WRAPPER class, never `AutoModelForCausalLM`.** For a
|
||||
multimodal-capable base (Gemma-4, Qwen3.6), `AutoModelForCausalLM.from_pretrained` +
|
||||
`save_pretrained` writes a FLAT text config (`Qwen3_5TextConfig`, `model.layers.*`) that
|
||||
**both vLLM AND SGLang reject** (SGLang: "Qwen3_5ForCausalLM has no SGLang implementation";
|
||||
vLLM wants `Qwen3_5ForConditionalGeneration`). Loading via `Qwen3_5ForConditionalGeneration` /
|
||||
`Gemma4ForConditionalGeneration` keeps the wrapper config they accept. **This was the DS
|
||||
blocker** — re-quant via the wrapper fixed it (`Dark-Scarlett-...-NVFP4A16-wrapper`).
|
||||
2. **NVFP4A16 is weight-only → DATA-FREE.** llm-compressor infers `DataFreePipeline`; calibration
|
||||
data is unused (only matters for W4A4 activation quant). W4A16 chosen per NVIDIA's sm_120
|
||||
long-context guidance (W4A4 KLD 2-4× worse past ~10k ctx).
|
||||
3. **Load on CPU (`device_map=None`)** so llm-compressor onloads one layer at a time. `device_map=
|
||||
"auto"` packs the whole model onto the GPU and OOMs when the card isn't fully free.
|
||||
4. **Both models are KV-EFFICIENT — the "dense = KV-hungry" worry was WRONG.** MeroMero (Gemma-4)
|
||||
uses **sliding-window attention** (most layers cache only a bounded window); DS (Qwen3.6) uses
|
||||
**hybrid GatedDeltaNet linear-attention** (3:1 linear:full, linear layers carry no KV). Both
|
||||
hit full native 256K easily. (MeroMero KV pool ~542K tokens at util 0.52.)
|
||||
5. **MeroMero vision reconstruction.** The finetune ships `processor_config.json` (image_processor
|
||||
inline, `Gemma4ImageProcessor`) but NOT `preprocessor_config.json` — the old-format file vLLM's
|
||||
feature-extractor loader wants. **Even google/gemma-4-31B-it (ungated!) ships only
|
||||
processor_config.json.** FIX: extract the `image_processor` section → write
|
||||
`preprocessor_config.json` verbatim, serve WITHOUT `--language-model-only`. Verified (model
|
||||
correctly ID'd a red circle). Audio is config-declared but WEIGHTLESS (0 audio tensors).
|
||||
6. **GPU placement.** Match the KV-heavier model to the roomier GPU. GPU0 (gen neighbor, ~54GB
|
||||
free) > GPU1 (utility cluster, ~45GB free). Swapped MeroMero→GPU0, DS→GPU1. Pins via compose
|
||||
`deploy.resources.reservations.devices`.
|
||||
|
||||
## Dead ends (tried + abandoned)
|
||||
|
||||
- **DS via llm-compressor `AutoModelForCausalLM`** → flat config vLLM/SGLang reject. → wrapper class.
|
||||
- **DS via NVIDIA ModelOpt** → modelopt↔transformers **version deadlock**: current transformers
|
||||
supports `qwen3_5` but crashes modelopt's sparse-moe plugin (`issubclass()` on a non-class);
|
||||
modelopt 0.43.0 pulls an old transformers that can't load `qwen3_5` at all. Abandoned.
|
||||
- **DS via SGLang** → `Qwen3_5ForCausalLM has no SGLang implementation`. Abandoned, but it REVEALED
|
||||
that both engines need the wrapper (→ the fix in lesson 1).
|
||||
- **`device_map="auto"` for the quant** → CUDA OOM in the weight observer. → `device_map=None`.
|
||||
|
||||
## granite retired + gateway repoint
|
||||
|
||||
- `vllm-granite` (granite-4.1-8b, fleet summarizer, GPU1) **`docker stop`ped** (reversible) to
|
||||
reclaim ~13.6GB GPU1 for RP context.
|
||||
- LiteLLM (`ana-docker:/opt/docker/conf/litellm/config.yaml`, backed up
|
||||
`.bak-pre-granite-down-*`): **`granite-4.1-8b` alias RETIRED** — commented out, now 404s cleanly
|
||||
(the `*` wildcard→llama-swap was decommissioned 2026-06-20, so no fallthrough). **`summarizer` +
|
||||
`classifier` REPOINTED to gen** (`hosted_vllm/qwen3.6-35b-a3b-heretic` @ :8015,
|
||||
`enable_thinking:false`) — both verified. ⚠ This LiteLLM change is **server-only / not
|
||||
version-controlled** (a follow-up).
|
||||
|
||||
## MTP — deferred
|
||||
|
||||
DS's MTP heads were dropped by the CausalLM loader; **deferred, not restored** (spec-decode is
|
||||
net-negative at RP temps: ~38-52% accept at temp 0.8-1.25, below vLLM's 0.5 cutoff). The
|
||||
splice-back path (`splice_mtp.py` in the heretic2 work dir) exists if ever wanted. MeroMero
|
||||
(Gemma-4) has no MTP by architecture.
|
||||
|
||||
## On-disk / where things live
|
||||
|
||||
- Quant pipelines: `ana-ml2:/tank/aimodels/meromero-v2-nvfp4-work/` +
|
||||
`/tank/aimodels/darkscarlett-nvfp4-work/` (scripts, BF16 source, NVFP4 outputs).
|
||||
- Compose stacks: `ana-ml2:/opt/docker/compose/{meromero-charrp,darkscarlett-charrp-reasoning}/`.
|
||||
- Gateway aliases (unchanged, port-based): `char-rp`→:8016, `char-rp-reasoning`→:8018. (char-rp was
|
||||
also fixed from the stale `magidonia-24b-v4.3` backend model name → `char-rp`.)
|
||||
|
||||
## Open follow-ups
|
||||
|
||||
1. LiteLLM granite/repoint change NOT version-controlled (server + backup only).
|
||||
2. eshpfi unpushed (many commits this session incl. `f08b6cb`, `7bd7375`, `398b58a`).
|
||||
3. MTP deferred (see above).
|
||||
4. DS thinks verbosely (~13:1 reasoning:content) — eval item; consumers need generous `max_tokens`.
|
||||
5. MeroMero full 256K needs util 0.55 (GPU0 ~1.8GB free, tight); ran at 0.52 for headroom (~4.6GB).

# `[2026-08-27]` Anaheim tripped a power breaker — and four guests including the NAS never came back
|
||||
|
||||
Site-wide outage, ~90 minutes. **Operator-confirmed cause: a tripped power breaker**, not a
|
||||
fault and not the tunnel. The discriminator that established scope: `ana-srv1`
|
||||
(38.120.12.44:443, Anaheim's PUBLIC address) was dark **from the internet**, so it was not the
|
||||
NH3↔ANA IPsec tunnel stranding NH3 — the site was not answering on any path. `ana-ml2` returned
|
||||
with `up 1 min`, confirming a hard power event.
|
||||
|
||||
## ⚠ THE DURABLE FINDING — `onboot` was unset on four guests
|
||||
|
||||
pfi-pve came back and auto-started everything **except**:
|
||||
|
||||
CT109 ana-nas the storage SPOF
|
||||
CT113 ana-wg the WireGuard remote-access path
|
||||
CT112 ana-filebot
|
||||
VM106 corviduo-dev
|
||||
|
||||
All four had `onboot` unset. **Recovery was manual and would have been manual every time** —
|
||||
including for the NAS that postgres/PBS/cross-site-restic depend on, and the WireGuard host
|
||||
that is the way in when the site misbehaves.
|
||||
|
||||
**FIXED, with dependency ordering** (operator-authorised):
|
||||
|
||||
CT109 ana-nas onboot=1 order=1,up=45 <- first; 45s for NFS to SERVE
|
||||
CT113 ana-wg onboot=1 order=2 <- remote access before anything can fail
|
||||
VM104/105 Mongo/Postgres order=3,up=60 (pre-existing)
|
||||
VM102 ANA-Docker order=4 (pre-existing)
|
||||
VM101 ANA-DC order=5,up=120 (pre-existing)
|
||||
CT112 ana-filebot onboot=1 order=10
|
||||
VM106 corviduo-dev onboot=1 order=10
|
||||
|
||||
Every guest on pfi-pve now auto-starts. ana-nas precedes the databases deliberately; the
|
||||
`up=45` is for NFS to be *serving*, not merely for the container to be *running* — the exact
|
||||
distinction that killed `rest-server` on ana-docker, which came up before the NAS existed,
|
||||
found nothing to serve, and exited 255.
|
||||
|
||||
## ⚠ `/tank` came back DEGRADED — a disk is genuinely gone
|
||||
|
||||
tank DEGRADED, raidz2-0, 7 devices ONLINE
|
||||
9477159196657038377 FAULTED was /dev/nvme4n1p1
|
||||
errors: No known data errors
|
||||
|
||||
**Only 7 physical NVMe present where the pool expects 8** — checked, so not renumbering. One
|
||||
drive did not re-enumerate. raidz2 carries two disks of parity; one is spent. Operator taking
|
||||
it; chassis is a Supermicro AS-4125GS-TNRT2 with PCIe hot-plug slots, so a swap should not
|
||||
need a power-down.
|
||||
|
||||
## ⚠ `/mnt/smithy` is manual by design — it will be missing after EVERY reboot
|
||||
|
||||
Not in fstab, and **deliberately so**: a cross-site NFS entry can hang boot on a GPU host, and
|
||||
it is `soft` rather than `hard` because ana-ml2 is cross-site from that NAS and a hard mount
|
||||
turns a link blip into unkillable D-state. Remount with the recorded spec, do NOT "fix" it into
|
||||
fstab:
|
||||
|
||||
sudo mount -t nfs4 -o ro,soft,timeo=30,retrans=3,proto=tcp,vers=4.1 \
|
||||
10.100.50.50:/volume1/smithy /mnt/smithy
|
||||
|
||||
Full rationale: [[2026-08-23-smithy-mount-ana-ml2]].
|
||||
|
||||
## Power capacity is now the open item
|
||||
|
||||
Operator: *"we'll triage this weekend, probably shut down some seats."* ana-ml2 alone was
|
||||
pulling ~600 W across both GPUs at their 300 W caps during training. `gen` stays up by
|
||||
instruction; everything else on that box is idle.
|
||||
|
||||
## Blast radius beyond us
|
||||

||||
heid lost **both gateway-routed arms of a four-arm panel** mid-dispatch and discovered the
|
||||
outage by losing half a panel. That report produced the single most valuable artifact of the

# `[2026-08-27]` The dose-response says benefit and damage are ONE direction in weight space
|
||||
|
||||
vLLM **cannot LoRA-serve Gemma-4-26B-A4B at all** — it is an MoE and the LoRA manager has no
|
||||
expert mapping (`AttributeError: To support LoRA for MoE model, 'get_expert_mapping' must be
|
||||
implemented`, `vllm/lora/utils.py:398`, v0.24.0). Found by trying it: one container start,
|
||||
which is exactly what playbook §3.10 exists to buy.
|
||||
|
||||
So each scale point was **pre-merged** instead — `merge_and_unload` with the adapter's alpha
|
||||
pre-scaled, which reproduces exactly what a LoRA at scale s would serve, on the same serving
|
||||
path as the gate. Artifacts held at `/tank/erp-tune/serve/merged-run03{,-s075,-s050,-s025}`.

first 42% of the gain costs 3.12pp of noise coherence
|

last 58% of the gain costs 37.50pp more -> 12x worse per point
|
||||
|
||||
**Every axis is monotone in scale — attractor, distance, marker density, RP length, both
|
||||
coherence measures, even truncation count. No knee anywhere.**
|
||||
|
||||
## The conclusion, which is stronger than an exchange rate
|
||||
|
||||
An exchange rate says the trade is expensive. This says **there is no trade to make**: the
|
||||
adapter learned ONE direction and everything rides it. brokkr's framing, worth keeping:
|
||||
**scaling moves you along the direction the adapter already learned; it cannot give you a
|
||||
different one.**
|
||||
|
||||
That converts the merge-back from a candidate fix into a **measurement of the problem**.
|
||||
zerofata's MeroMero v1 ships the merge-back as its answer, so it was worth testing — and
|
||||
testing it is what proved it cannot be the answer here.
|
||||
|
||||
## The T4 mechanism is NOT register capture
|
||||
|
||||
pad type base tuned
|
||||
prose 1.0000 flat mild knee, onset ~1,600 tok
|
||||
noise 1.0000 flat 1.0000 -> 0.5938 <- SEVERE
|
||||
|
||||
The prose-gradient "wedge" predicted **prose** should be the worst case. Instead prose is the
|
||||
mild axis and **shuffled tokens are where it collapses** — a continuation prior has nothing to
|
||||
continue in shuffled tokens. Every miss is `wrong-name`: correct format, on task, wrong answer.
|
||||
**State mis-tracking, not register capture.**
|
||||
|
||||
brokkr: *"The tune did not teach it to continue prose — it destroyed its ability to skip text
|
||||
that is not worth reading."*
|
||||
|
||||
## ⚠ INSTRUMENT FLOOR — temperature 0 is NOT deterministic under concurrency
|
||||
|
||||
same seat, same items, temperature 0, --jobs 8
|
||||
prose reps 31 0.9375 0.9688 0.9688 spread 3.12pp

||||
noise reps 24 0.7500 0.7188 0.7188 spread 3.12pp
|
||||
|
||||
vLLM's continuous batching is not numerically invariant to batch composition. **Any eval delta
|
||||
under ~3.1pp at n=64/jobs=8 is inside the floor.** Only `--jobs 1` shrinks it; more n averages

over it. Also in auto-memory as

`reference_vllm_temp0_not_deterministic_under_jobs`.

# `[2026-08-27]` A transport failure that enters a measurement as a VALUE looks like whatever you hoped to find
|
||||
|
||||
The most transferable thing the Anaheim outage produced, and it came from a peer losing half a
|
||||
panel rather than from anyone investigating.
|
||||
|
||||
## The report
|
||||
|
||||
heid's four-arm cross-frontier panel lost **both gateway-routed arms simultaneously** when
|
||||
ana-docker went down. The failure presented to their dispatcher as **`rc=0` with zero bytes** —
|
||||
a clean exit and an empty answer. Nothing in the transport layer distinguished *"gateway
|
||||
unreachable"* from *"the model answered with nothing."*
|
||||
|
||||
## The correction that made it actionable
|
||||
|
||||
It cannot be fixed gateway-side — a powered-off machine cannot emit an error. **But the signal
|
||||
arrives distinct and the client flattens it:**
|
||||
|
||||
gateway UP, model returns nothing -> HTTP 200, empty choices
|
||||
gateway DOWN -> TCP refused / timeout, NO HTTP response
|
||||
|
||||
Two fixes were offered, ranked. **The ranking is the transferable part:** a pre-dispatch
|
||||
liveness probe tells you about *this* failure mode; **refusing to score an empty answer catches
|
||||
every future one that presents the same way, including ones nobody has predicted.**
|
||||
Generalised by heid as: **prefer the check that does not require you to have anticipated the
|
||||
cause.**
|
||||
|
||||
## ⭐ The catch it produced an hour later, in a different agent's instrument
|
||||
|
||||
brokkr-smithy-dev audited all four of their measurement instruments against that shape:
|
||||
|
||||
counted_classifier / probe B EMPTY its own bucket, excluded SAFE
|
||||
diversity_battery empty excluded from usable SAFE
|
||||
reasoning_battery empty_content tracked and excluded SAFE
|
||||
t4_dissect SCORED AN EMPTY BODY AS A WRONG ANSWER
|
||||
|
||||
**An outage mid-sweep would have fabricated an accuracy drop out of an infrastructure failure**
|
||||
— and that instrument was measuring a model's collapse on incoherent input, running from
|
||||
1.0000 down toward 0.56. **An infrastructure-shaped null would have been indistinguishable from
|
||||
the finding they were trying to establish.**
|
||||
|
||||
Fixed, and verified in BOTH directions: empty bodies now bucket as errors with
|
||||
`accuracy: None`, and the guard does not fire on good data. **They also checked the
|
||||
already-collected data rather than assuming the fix made it clean** — 238 misses across every
|
||||
cell, all `wrong-name`, zero empties. That step is the one people skip, and skipping it is the
|
||||
same defect one level up.
|
||||
|
||||
## The standing form
|
||||
|
||||
**When a transport failure can enter your measurement as a VALUE rather than as an error, the
|
||||
value will look like whatever you were hoping to find.** Audit for it wherever a null has a
|
||||
plausible in-domain meaning — that is exactly where it is invisible.
|
||||
|
||||
Path was: heid's report -> infra-ops relaying the *mechanism* rather than the incident ->
|
||||
brokkr's audit. Three agents, none working on the same thing, inside an hour. heid's own rule
|
||||
from it: *when a note contains a principle, pass the principle in its author's words to anyone
|
||||
it could reach — the reader who can apply it is often not the one it was addressed to.*

# `[2026-08-27]` The corpus mix was specified in a unit the optimiser never sees
|
||||
|
||||
Run 3's recipe specified its mix as **context shares** — dialogue 45.8% / kvasir 38.0% /
|
||||
fireball 16.2% — and was approved, built and trained on that basis.
|
||||
|
||||
**As TRAINED the gradient was 24.2% dialogue and 75.8% prose.**
|
||||
|
||||
effective_mix, adapter provenance.json, LOSS shares
|
||||
kvasir 0.5310
|

fireball 0.2271 prose 75.81%
|
||||
c2-logs 0.0861
|
||||
cwm 0.0763
|
||||
bluemoon 0.0796 dialogue 24.20%
|
||||
|
||||
Not a reinterpretation — **the trainer wrote both numbers into the same manifest and nobody
|
||||
read the second one**, across three runs.
|
||||
|
||||
## The mechanic
|
||||
|
||||
F2/F3/F4 mask loss off dialogue turns while leaving their context in place. So **the harder
|
||||
the dialogue filters work, the more prose-dominant the gradient becomes.** Every mix ruling
|
||||
was made in the wrong unit.
|
||||
|
||||
## Why it survived review
|
||||
|
||||
infra-ops set kvasir's subset to 38.0% *of context* because that is the unit the recipe stated
|
||||
a share in, and because fireball's 12% landed exactly on context — which was read as
|
||||
confirmation the recipe meant context throughout. It did. **The specification was in the wrong
|
||||
unit and it was matched faithfully**, which is a worse failure mode than an arithmetic error
|
||||
because every check agreed with it.
|
||||
|
||||
## The fix — a RENAME, not a reordering
|
||||
|
||||
Harness commit `dd5a12e` (eitri-smithy). Both numbers were already printed, adjacent, with
|
||||
context first — and that was enough for three runs of people reading the wrong one. Demoting
|
||||
context would not have stopped a fourth.
|
||||
|
||||
[mix] LOSS share is what the optimiser sees. ctx share is a memory budget, NOT the mix.
|
||||
[mix] kvasir loss 0.5310 [memory budget: ctx 0.3800]
|
||||
|
||||
Calling it a *memory budget* makes "the mix is 38% kvasir" a sentence someone has to actively
|
||||
mis-say. Found by brokkr-smithy-dev's CPU arm after the run-3 gate.

The preregistered rule reads the **pooled** operational delta: **−1.0pp against a ±3.00pp
|
||||
bound. It PASSES.** Nineteen axes held at 5/5, so a 44-point collapse on one axis moved the
|
||||
aggregate by a single point.
|
||||
|
||||
**The rule was NOT retroactively changed.** The gate passed, the report says so, and the
|
||||
finding stands beside it as a stated follow-up. brokkr flagged the failure mode as R47 §8
|
||||
item 11 **before** running the follow-up, which is the only reason it reads as a result
|
||||
rather than as rationalising an inconvenient pass.
|
||||
|
||||
**Any future preserve-list gate needs a per-axis tripwire beside the pooled test, sized so a
|
||||
total loss on one axis cannot hide in an aggregate.**
|
||||
|
||||
## What is NOT claimed
|
||||
|
||||
Not attributed to the filters — five things changed between run 2 and run 3 and there is no
|
||||
run-2 measurement on these axes. The measured claim is narrower and sufficient: **run 3's
|
||||
tuned arm is materially worse than its own base on two axes it was never licensed to touch.**
|
||||
Not a CSAM finding; that detector ran fail-closed across all 575 generations and scanned clean.
|
||||
|
||||
## Disposition
|
||||
|
||||
**DO NOT SERVE.** `merged-run03` was withdrawn from the LiteLLM gateway (commit `5a51e76`)
|
||||
~72 minutes after being added at operator request, and the config entry carries the finding
|
||||
in-line above a deliberately commented-out `model_list` block so a re-add is informed.
|
||||
|
||||
Operator ruling later that evening: **safety moves to a front-end model**, so guardrail
|
||||
behaviour stops being a selection axis for the tune. brokkr's framing, which should be quoted
|
||||
verbatim in the artifact: *"read it as the finding being routed, not softened."* The p-value
|
||||
and the disposition must stay adjacent in the record even though the disposition changed.
|
||||
|
||||
⚠ Regardless of where safety lives, `merged-run03` stays off the shared-key gateway. A
|
||||
front-end guard protects a product path, not every agent on the fleet that can list models.
|
||||

|

|
||||
- **🔴 RUN 2 GATE: FAIL, recorded as FAIL.** T3 constraint **−12.0** and T4 −5.5 against a ~1 pt floor (both tuned passes read 88 exactly — not variance). **But gate 1 is the result: T6 spatial +15.0, where run 1 FAILED the same axis at −3.5**, base swap the only intended variable. Neither run ships; together they price what the abliteration cost. Diversity **+0.1934 at 23.6x sd** over eight independent blocks — the most robust number produced, survived attrition-matching and the opposite-direction length argument. Memorisation none. Full write-up: brokkr `4973991`, `research/R47-premium-corpus-gate/run02-gate/RESULT-run02-gate.md`. → `persistent-memory.d/2026-08-26-erp-run2-complete-and-served.md`
|
||||
- **⚠ THE "INSTABILITY" WAS NEVER INSTABILITY — I published this wrong TWICE and corrected it.** All 46 flags were **`too_short`** rp turns of 3-14 words; the two collapse guards (`repeated_trigrams`, `non_latin`) fired **zero** times on any run. The model never collapsed. It is the **left tail of the length distribution measured in the same message** — thresholds calibrated on the base's output shape applied to a model with a different shape. It was also **not new**: run 1's record carried it, so it is a property of the RECIPE, not the base swap — **a third run that changes the base again will not fix it.** Playbook §4.6.3 carries the corrected version with the retraction visible.
|
||||
- **🟢 `erp-tune-v2` SERVING + ON THE GATEWAY** (`10.250.50.70:4000` and direct `:8098`, GPU0, shared all-agents key works). Operator's explicit request so he can evaluate it by hand — **overrides my not-in-the-gateway recommendation.** The config entry carries the failed-gate table, truncation/degeneracy rates and rp-length caveat IN-LINE. **`erp-tune-v1` DELETED from the config** in the same reload: clean **400** now, not the 500 it had been throwing. ⚠ **Never repoint v1 at v2's weights to silence an error.**
|
||||
- **⏸ RUN 3: CORPUS BUILT, LAUNCH HELD — brokkr is redoing the recipe.** Blocker found before any GPU spend: **`creative-writing-multiturn` is a declared MEGAMIX containing bluemoon, PIPPA, LimaRP and stheno**, and the remix promoted creative-writing *and* bluemoon — the two roots that overlap. Median bluemoon↔creative-writing jaccard **0.873**; containment, not overlap. Dedup direction **reversed** (keep the primary source, drop the megamix copy) → bluemoon 67→126 convs and **38.6% of loss signal, the largest contributor**, wholly-human share UP and megamix share DOWN, context unchanged at 12.49M so the operator's settled mix survives. ⚠ **F1 "excise PIPPA" removes the ROOT not the MATERIAL** — F2's 250-word floor does that work, since PIPPA turns cannot exceed 123 words wherever they live. → `persistent-memory.d/2026-08-26-run3-corpus-and-the-megamix-containment.md`
|
||||
- **⚠ CATALOG-LEVEL, UNSOLVED: LimaRP and stheno are still unchecked against anything.** A megamix root silently contains other catalog roots and the mix arithmetic does not know. Wants a `contains_datasets:` Hoard field + a preflight assertion that no recipe includes both a megamix and a root it contains. brokkr raising it as its own item.
|
||||
- **⏳ DPO BLOCKED on an operator decision: which refusal axes are pruned vs explicitly kept.** `docs/pfi/erp-dpo-stage-prep.md`. No preference data for refusal axes exists; `trl` is not installed; the Gutenberg sets on disk are prose-quality only. ⚠ **`under_floor_rate_run02 = 11.78% [9.49, 14.07] @ floor 15, corpus = run-02 mix` is bound to run 2's mix and is obsolete the day the remix is built.** ⚠ The rp length distribution is **bimodal** — pairs sampled from it inherit the mixture, not a mean.
|
||||
- **⚠ HARNESS COMMITS LOCAL AND UNPUSHED** on ana-ml2 `/tank/erp-tune/eitri-smithy` (`5349ef0` → `9d27b4f`, 242 tests green). Push is the operator's call.
|
||||
- **🟢 SEATS.** GPU0: `erp-tune-v2` (:8098, ~13 GB spare) — **operator granted discretion to take it down; I left it UP** because the card is not needed until a recipe is settled. GPU1: `gen` (:8015), scriberr, rerank-a3, coder, reward, embed. **`char-rp` and `sec`/mog-sec still DOWN** from the training window.
|
||||
- **⏳ OPEN ELSEWHERE (unchanged):** Worldtree #411 orphan cleanup + providers.yaml parity + `:latest` tag cleanup (selene fix `a77639d` committed NOT deployed); synapse stack not mirrored into `stacks/`; MTP-k3 isolating experiment; upstream vLLM issue to file; Cold-Fusion NVFP4 quants delete/keep; `/tank` DEGRADED **70+ days**; Lobe retirement.
|
||||
- **⚠️ STANDING: NO FLEET NOTIFICATIONS unless the operator asks** (2026-08-24).
|
||||
- **⏸ RUN 3c HELD — operator stopped it, power capacity is the blocker.** lr `2e-4 -> 1e-5`, corpus BYTE-IDENTICAL, single variable proven by diff. Config `/tank/erp-tune/run-03c.json` is built and validated (`save_steps 50`, both deviations recorded as separate entries — the scientific lr change and the operational checkpoint cadence). Relaunch is one command. **Do not relaunch until the power triage lands** — ana-ml2 pulls ~600 W across both GPUs at their caps while training, and that is what tripped the breaker.
|
||||
- **🔴 `/tank` DEGRADED on ana-ml2 — a disk is genuinely gone**, 7 physical NVMe where the pool expects 8. raidz2, one parity disk spent, no data errors. **Operator is replacing it** (Supermicro AS-4125GS-TNRT2, PCIe hot-plug, should not need a power-down). → `persistent-memory.d/2026-08-27-anaheim-breaker-and-onboot-gap.md`
|
||||
- **🟢 ADAPTERS BACKED UP OFF-SITE** — `nh3-nas:/volume1/smithy/erp-tune-adapter-backup/{run-01,run-02,run-03}`, sha256 verified at source, staging and rest (944 MB). They were single-copy mode-600 on the degraded pool. The four `merged-run03*` models are NOT backed up **by design** — all are derived from `run-03/adapter` by a documented verified merge, ~10 min each to regenerate from a 315 MB artifact that is now safe.
|
||||
- **⏸ WEEKEND: power triage, "probably shut down some seats"** (operator). `gen` stays up by instruction. Everything else on ana-ml2 is idle. Sheddable: `vllm-gen` 46 GB (the big one), embed 9.8 GB, coder 8.4 GB, rerank-a3 3.5 GB, reward 2.1 GB, scriberr.
|
||||
- **⏸ Owed to brokkr-smithy-dev when there is a card again:** nothing blocking. They hold the dose curve, the entanglement finding, and an unsourced "~60%" figure in R47 §5 they were checking against MeroMero v2's card — if it is not there either, §5's recommendation loses its basis.
|
||||
- ⚠ **`/mnt/smithy` will be MISSING after every ana-ml2 reboot** — manual by design, not an oversight. Remount spec in `persistent-memory.d/2026-08-23-smithy-mount-ana-ml2.md`. Do NOT add it to fstab.

|
||||
- `[2026-08-27]` **Run 3c authorised (lr 20x cut, single variable) and then HELD by the operator after the breaker trip.** Config built and validated at `/tank/erp-tune/run-03c.json`; `save_steps` made configurable in the harness (`0a6bd2e`) because the first launch lost 80 steps with no checkpoint. Tracking surface: commit `0a6bd2e` + that config path. **Relaunch is one command once power is triaged.**
|
||||
- `[2026-08-27]` **`save_steps` was hardcoded at 100 in the harness** — a claimed provenance entry the run could not have honoured. Made configurable, default unchanged (`0a6bd2e`, 242 tests green). Caught by checking the config carried the change rather than trusting that it had been made.
|
||||
- `[2026-08-27]` **Six defects in run 3's staged build, none of which would have errored** — a dialogue-only survivor list that would have silently dropped 96% of the corpus, an impersonation mask not subsumed by the low-quality mask, kvasir unbounded at 67.8% of context, a `save_pretrained` config-key drop that made the merged model unservable, and the mix-unit error. Every one produced a plausible completed run. Full record `/tank/erp-tune/recipe-r3/RUN-03-BUILD-NOTE.md`.
|
||||
- `[2026-08-27]` **The 18 unpushed eitri-smithy commits are pushed** — run 3's `harness_commit 9d27b4fe` now resolves off-box, verified by fetching into a fresh empty repo rather than trusting the push output. ⚠ **HTTPS push 403s for every gitea token including site-admin; SSH works.** Untracked `__pycache__` (`894fbe8`) because a tracked `.pyc` dirtied the tree and would have stamped `harness_dirty_at_launch: true`.
|
||||
|
||||
- `[2026-08-26]` **Run 3's corpus is built and HELD — `creative-writing-multiturn` is a MEGAMIX containing bluemoon, PIPPA, LimaRP and stheno**, and the remix promoted two roots that overlap at median jaccard 0.873. Dedup direction reversed to keep the primary source. F1 does not do what the recipe says; F2 does. → `persistent-memory.d/2026-08-26-run3-corpus-and-the-megamix-containment.md`
|
||||
- `[2026-08-26]` **No conversation admission threshold for run 3** (brokkr delegated, then endorsed). Masked context costs the transformer body but NOT the LM head — the harness drops `IGNORE_INDEX` before the 262k-vocab head — so a 20% trim buys ~35 min against a 3-hour run, and it would be a fifth filter confounding a run whose purpose is testing the filters alone. Tracked in the run-3 detail file.

New repo `~/development/tts-stack` (commit `9ee3288`) carries: dots-tts stack (canonical intent), `voices/` corpus (MOVED out of eshpfi), `KNOWLEDGE.md` (engine landscape + prosody findings + foot-guns), `docs/infrastructure.md` (irv-ml1 access + gated deploy runbook + rollback), CLAUDE/persistent-memory/ROADMAP, `tools/` (pause-probe + Booth render). Followed the **chatterbox-fast precedent**: eshpfi `stacks/dots-tts/` reduced to a POINTER README; the ~15 experimental TTS compose wrappers stay here as reference (catalogued in tts-stack KNOWLEDGE). Blast-radius check: no eshpfi playbook/script reads the canonical corpus (other `voices/` refs = unrelated host paths). **Reverses** the earlier "Corpus home = eshpfi `voices/` (keep-here)" call. ⚠ tts-stack is LOCAL-ONLY until pushed — needs a gitea remote (`vh/tts-stack`) + push before the separate agent can clone (operator's call — outward-facing + repo-create creds).

|
||||
- `[2026-08-10]` **dots-tts v3 — clause-break → period pause mapping.** Operator: v2 "sounds good" but donut won't pause at semicolons/dashes. ROOT CAUSE (measured via a pause-probe A/B — synth duration over N runs, non-determinism averaged out): dots' prosody honors a real pause **only for ellipsis (~+0.43s) and period (~+0.3s, capitalization-independent)**; comma/semicolon/colon/dash all run **flat (~+0.03s vs no-punct)**. Two distinct sub-causes: **dashes regressed in v2** (the `—`→`-` fold made em-dashes read as word-joiners), while **semicolons were NEVER a v2 change** — dots ignores them natively, only newly noticeable because v2 made everything else clean. Operator call: ellipsis "too much" → **map `;`, clause `:`, and em-dash `—` → period** in `_sanitize` (believable ~0.3s clause break). GUARDS (pinned by 11 unit tests, `stacks/dots-tts/test_sanitize.py`): digit-guarded colon `(?<!\d)\s*:\s*(?!\d)` so times `3:45` / ratios `2:1` survive; en-dash `–`→hyphen KEPT (numeric-range `10–20` safety — em-dash breaks, en-dash ranges, different jobs); genuine ellipsis left at full strength (author meant a long pause). Gated deploy (redeploy2 pattern → v3): build → throwaway :8199 test container + **pause-gate** (semicolon sentence must run ≥0.12s longer than baseline; measured **+0.427s**) → only then cut live over.

ROOT CAUSE (isolated via A/B booth): **curly/typographic apostrophes** (`’` U+2019 from ratatoskr's LLM) — dots' tokenizer mispronounces them; STRAIGHT apostrophes read clean under `normalize_text=True`. FIX (`app.py`): fold curly→ASCII (`str.maketrans`) before synth, **KEEP `normalize_text=True`** (operator call — retains number/date expansion). Also added **server-side sentence-chunking** (pack ≤280 chars): dots caps one `generate()` at ~500 patches/~40s, so long RP turns (the Zev monologue = 160s audio) truncated; chunking stitches them (verified full 160.3s, not 40s-cut). **⚠ BUILD FOOT-GUNS (both bit this redeploy):** (1) upstream dots.tts `constraints/recommended.txt` now pins **`gradio==6.17.0` — phantom, not on PyPI** → fresh `pip install dots.tts` unsatisfiable; FIX = pin `dots.tts==0.2.1` + **DROP** the `-c recommended.txt` constraints (0.2.1 pulls working gradio 6.17.3). (2) pinning only `torch==2.8.0` let **torchaudio float to 2.11.0 → dots.tts refuses to load** (minor-version match check); FIX = pin `torchaudio==2.8.0`. **⚠ DEPLOY LESSON:** `docker compose up -d` to a new tag swaps the LIVE container BEFORE any health check — a broken image crash-loops production (**ratatoskr TTS down ~1-2min this session**). NEW PATTERN = build → test in a THROWAWAY container on an alt port (:8199) → health+verify → only THEN cut live over (redeploy2.sh). v2 LIVE + healthy on irv-ml1:8198, **CONSUMER-CONFIRMED clean** (ratatoskr verified end-to-end on their :8765 — apostrophe string reads clean, /api/tts 200 @ 48kHz, no client change; the ~1-2min blip didn't hit them, their concurrent auto-audio issue was client-side localStorage). **rollback = `sed DOTS_TAG=v1 + docker compose up -d dots-tts`** (v1 image retained). Also: deployed container GPU crept ~6→13.9GB over 8h serving (cache accumulation; a redeploy resets it — watch item). [[reference_chatterbox_fast_repo]]

- `[2026-08-09→10]` **dots.tts (rednote-hilab) TTS burn-in on irv-ml1 + canonical voice corpus built (`voices/`).** Operator-directed eval to potentially replace chatterbox-fast. **dots.tts VERIFIED real** (canonical HF ns `dots-studio/`, `rednote-hilab/dots.tts-*` redirects there; Apache-2.0; PyPI `dots.tts` 0.2.1; 2B continuous-AR = semantic enc + Qwen2.5-1.5B LLM + flow-matching acoustic head over 48kHz AudioVAE; zero-shot clone from wav+transcript). **Runs on Ampere 3090** (sm_86, bf16, no fp8 dep); **optimized RTF 0.22** at num_steps=10 (`from_pretrained(..., optimize=True)` CUDA graphs — raw unoptimized was 1.21), **~6GB VRAM**, 48kHz, streams (`generate_stream`). Venv+cache at `irv-ml1:/home/lkraven/dots-tts` (~10GB). **Operator design calls:** SGLang Omni serving (OpenAI `/v1/audio/speech`), transcribe-refs-first, `soar` variant. ⚠ Omni serves soar but its continuous-batching + streaming opts are **mf-only** (soar = single-request) — non-issue for ratatoskr's single-consumer RP surface. **KEY FINDING — dots is highly sensitive to an accurate AND sentence-bounded reference transcript:** mismatched transcript → 0.16s collapse; over-long/messy transcript → reference-audio BLEEDS as an output prefix; mid-clause trim → dangling-word leak (glados "we'll", emmie "And,"). RECIPE (baked into `voices/derive.py`): trim ref to a clean ~6–10s clip ending on a sentence boundary + accurate transcript of exactly that clip. **CANONICAL VOICE CORPUS** stood up in eshpfi `voices/` (operator idea): engine-agnostic `canonical/<v>.wav` + `transcripts/<v>.txt` → per-engine ref sets DERIVED by `derive.py` reading `engines.yaml` profiles (dots/chatterbox/zonos); canonical wavs git-tracked (small/curated), `derived/` gitignored. **4 voices optimized + verified CLEAN for dots: donut, glados, emmie, miranda** (glados canonical is low-SR 16kHz — flagged upgrade candidate). ⚠ GPU GOTCHA: irv-ml1 native CUDA orders **A6000=device0** (ComfyUI-full) — pin the 3090 with `CUDA_DEVICE_ORDER=PCI_BUS_ID CUDA_VISIBLE_DEVICES=0`; and `PYTORCH_CUDA_ALLOC_CONF=expandable_segments` CONFLICTS with `optimize=True` CUDA graphs (curr_block error). Booths: `dots-vs-chatterbox`, `dots-voices-optimized`. **SHIPPED 2026-08-10:** operator A/B verdict "dots is very good" → containerized as a **thin FastAPI wrapper over DotsTtsRuntime** (chosen over SGLang Omni — Omni's batching is mf-only, unneeded for ratatoskr's single consumer; wrapper is SERIALIZED one-gen-at-a-time via a threading.Lock, Omni+mf = parked API-compatible escalation if multi-consumer ever lands). **LIVE on irv-ml1:8198** (`local/dots-tts:v1`, OpenAI `/v1/audio/speech` + `/health` + `/v1/voices`, container healthy, both stream + non-stream verified CLEAN, 4 voices donut/glados/emmie/miranda) alongside chatterbox :8197 (nothing repointed). Stack = `stacks/dots-tts/` (Dockerfile/app.py/compose/.env.example/README). ⚠ CONTAINER GOTCHA: `optimize=True` (torch.compile/inductor/triton) needs a **C compiler at RUNTIME** — slim image must `apt install build-essential` or model-load dies "Failed to find C compiler" (host venv had gcc ambient, masking it); persist `TORCHINDUCTOR_CACHE_DIR` to a mounted dir or every restart re-JITs ~5min. Corpus home = eshpfi `voices/` (operator ruled keep-here). **REMAINING: ratatoskr client cutover** to :8198 `/v1/audio/speech` (Phase-2 tail, peer-coupled — draft the ask).

- `[2026-08-25]` **Four throughput levers measured and killed — do not re-chase.** (1) **Fused MoE / `grouped_mm`** — 0.9% *slower* than the Python loop and dense GEMM is only 7.9% of the step, capping the whole category near 10%. (2) **CUDA graphs / `torch.compile` over the expert loop** — the two-term scaling fit closed with residuals under 3ms and needed NO constant term, so there is no fixed per-batch cost to amortise; 3,840 expert-GEMM launches per forward are not what we pay for. (3) **`liger` fused linear CE** — the chunked CE measured **1.1% of the step** forward, ~3% with recompute. A tidy-up, not a lever. (4) **Selective gradient checkpointing** — ~2% of a post-fix step, real bug surface. Also: **token-budget batching is dead by the same fit** — with no constant term, total time over a fixed set of widths is invariant to how you group them; only the widths matter, which is exactly why bucketing works and repacking does not.
