# Persistent memory — eshpfi-management

_Last updated: 2026-07-11_

## Repo purpose

Reference workspace for PFI infrastructure: server inventory, canonical
Docker Compose stacks, ops playbooks, and conventions. Authoritative
copies of compose files live on the servers under
`/opt/docker/compose/<stack>/`; this repo mirrors them for version
control, editing, planning, and CI-driven deploys. **It was originally
spun up to handle the fleet backups** — keep that lens when triaging
backup/storage issues.

## Tools and conventions

Sister repos (separate gitea repos, deployed by playbooks here):

| Repo | Role | CI status |
|---|---|---|
| `vh/task-board` | MCP + web dashboard for assistant task state (port 7878) | push-to-main → CI deploys (2026-04-29) |
| `vh/vor` | Inquisitor UI sidecar (port 7879) | push-to-main → CI deploys (2026-04-29) |
| `vh/nevermore` | Twice-daily LLM-curated briefing (port 8181, replaces news-digest) | push-to-main → CI deploys (2026-04-30) |
| `vh/asset-engine` | Internal control plane over inference services (port 8200, LAN-direct) | push-to-main → CI deploys (2026-05-12) |
| `vh/althing` | Lean trusted inter-agent message bus — **v2 "email model" (v2.0.0b2, 2026-07)**: per-box local-SQLite bus + courier/receiver for P2P over the 10.x net; pillars = open-loops / per-box herald + wake-listener / roaming owner API `/owner/*` / `althing-mcp` stdio surface. The v0.15 lean-bus cut RIPPED moderation / chamber / forseti-daemon / agent-runner / redis-valkey. | per-box `uv tool install` (NOT CI-deploy); **nh3-dev = the DEV box** (editable install of `~/development/althing`, gets new versions first); **nh3-extdev** a mesh peer (model B: althing-svc + shared `/srv/althing`) |
| `vh/mead-hall` | Bifrost tool-provider sidecar (port 5173 on dev VM 10.100.10.50) | push-to-main → CI deploys (2026-05-16) |
| `vh/skaldsong` | Wizard + reader surface (port 8300, ana-docker, registry-pull pattern) | push-to-main → CI deploys (2026-05-19) |
| `vh/Worldtree` | Conversation API (corviduo-dev demo :8080 / personal :8081 / pinned :8082) — Heimdall auth, Bifrost integration. **gitea-runner builds on ana-docker**; claude-bot ADMIN collaborator (2026-06-20). Now v1.0.0b19. | push-to-main → CI build-and-deploy (runner on ana-docker) |
| `vh/yt-voice-clipper` | YouTube → diarized voice-clip dataset builder + audition console (irv-ml1 :8000) | push-to-main → **gitea-webhook auto-deploy** to irv-ml1 (2026-06-03) — see `docs/runbooks/ytvc-autodeploy.md` |
| `vh/arbo` | Catalog-driven ComfyUI engine (irv-ml1 :8201, comfy-dev owns engine/catalog/image) | push-to-main → gitea Actions CI (deploy-engine.sh, build-local, health-gated) now LIVE; catalog via :9009 webhook |
| `model-training-forge` (mtf-dev) | Fine-tuning recipe forge; **T1 = E-RP writing LoRA, retargeted qwopus-122B→AEON-27B (2026-07-06)** (SFT→DPO, LitBench-RM reward) | training runs, not a deployed sidecar |

(`vh/volva` + Heid were re-architected from systemd daemons to Claude Code
session orchestrators 2026-06-08; their nh3-dev `.service` units were removed —
no longer deployed sidecars here. See Recent decisions.)

- **Two-layer backups** — Backrest orchestrates restic for file+DB (5
  fleet repos, daily 01:00 PDT); PBS-ANA primary + PBS-NH3 DR mirror for
  VM images. ana-nas is the SPOF for postgres + PBS-ANA datastore +
  cross-site restic targets — see `docs/runbooks/disaster-recovery.md`
  for the blast-radius matrix. **⚠️ The restic file+DB layer routes
  through TWO rest-servers** (`rest-server-ana` @ ana-docker:8000 →
  ana-docker/ana-ml2/esh-docker-vm/vm-esh-nas; `rest-server-nh3` @
  nh3-nas:8000 → irv-ml1/nh3-docker). Both depend on their NAS's NFS
  export of `/mnt/backup`. (rest-server-ana recovered 2026-06-20.)

- **`pull-hf-repo.yaml`** is the canonical "get a HuggingFace
  model/dataset onto ana-ml2's shared cache at
  `/tank/aimodels/huggingface/`" playbook. Supports `--var repo_type=model|dataset|space`. Replaces ad-hoc `huggingface_hub.snapshot_download` patterns.

- **Worldtree admin auth — per-instance.** Each Worldtree deployment
  (demo :8080, personal :8081, pinned :8082) has its own Heimdall
  registry and its own bootstrap admin key. Infra-ops's stored
  long-lived admin key (`key_id 61419c92`) at
  `ana-docker:/opt/docker/conf/.secrets/worldtree-infra-ops-admin`
  auths against **demo only**. Personal-instance admin (the
  `~/.config/worldtree/personal-admin-token`, mode 600) POSTs
  `/admin/keys` (mints per-project keys; takes `user_id`+`label`, **no
  scope param** — scopes are tier-derived). **On-instance mint recipe
  (cleaner than DB-manip):** `docker exec worldtree-worldtree-api-1` POST
  `/admin/keys` with the in-container `WORLDTREE_BOOTSTRAP_ADMIN_KEY`; cleartext
  once in `.key`=`wt_live_+16hex`. auto-memory `reference_worldtree_demo_key_mint`.

- **Per-project user keys against personal Worldtree** (issued
  2026-05-19): `skaldsong:79744637`, `skaldsong:7c1dbbbe`,
  `althing:50d85460`, `mead-hall:a360822d`. Mint via `/admin/keys`, drop
  value to `/tmp/wt-personal-<name>.key` mode 600, dev collects +
  shreds (DO NOT cat to chat transcript).

- **Skaldsong CD pattern (registry-pull).** vh/skaldsong's CI builds and
  pushes `gitea.phasefinal.com/vh/skaldsong:<sha>` + `:latest`;
  `playbooks/deploy-skaldsong.yaml` on ana-docker pulls + recreates.
  SHA-pin only. Prereq: host needs `docker login gitea.phasefinal.com` once.

- **gitea internal route for fleet hosts.** gitea is a container on
  **ana-docker** — git-SSH `10.250.50.70:222`, HTTP `:3000`. Fleet/colo
  hosts must use this internal route, NOT public `gitea.phasefinal.com`
  (`38.120.12.44`) — the public path fail2bans the host egress IP. Full
  gotcha in `docs/orientation.md` → Git/gitea.

- **docker-as-root pattern** (for ops with no admin API, or to edit
  deploy-owned/root-owned files without sudo): `docker run --rm -v
  <target-dir>:/wt docker:cli sh -c "..."`. docker-group membership is
  effectively root via bind-mount. **Foot-gun: relative paths in compose.yaml
  resolve against the sandbox CWD but the daemon interprets them against the
  HOST fs — always pass `-e VAR=/abs/path` for any relative-default config dir.**

- **`scripts/elway` sudo handling** — elway prompts for the sudo password
  ONCE via `getpass` before the first `sudo: true` step → can't run
  unattended from a non-TTY tool if any step needs sudo. Sudo-free
  playbooks run fully non-interactive over key SSH.

- **Per-host SSH identity matters for sudo.** infra-ops has NOPASSWD sudo
  on most PFI Linux boxes (corviduo-dev included since 2026-06-15). On
  ana-docker: **default `ssh ana-docker` = `lkraven`** (docker-group, NO
  passwordless sudo); **`ssh infra-ops@ana-docker` HAS NOPASSWD root**. **→
  For any sudo op on ana-docker, use `ssh infra-ops@ana-docker`.** `ssh
  infra-ops@10.100.10.50` (nh3-dev) ALSO NOPASSWD sudo; on **nh3-extdev** infra-ops
  is sudo-LESS by design (`ssh lkraven@10.100.50.42` is the NOPASSWD path). **irv-ml1:
  `ssh irv-ml1` = lkraven, docker-group (plain docker) but sudo needs a PASSWORD
  (no NOPASSWD)** — stage model pulls to `/home`, not root-owned `/worktank`.

## Current state / in-flight

_As of 2026-07-11 — the R17 TTS audition CONCLUDED and **Zonos was productionized** (won the expressive tier →
shipped as the `zonos-gateway` stack, below). Fleet changes this session: **omnivoice RETIRED**, **vllm-morpheus
KILLED** (operator: unimpressive), **ComfyUI TAKEN DOWN** (A6000 freed for the audition; comfy-dev PARKED — the
v0.27.1 bump it validated stays LANDED, just not running). **Higgs** auditioned well + streams (room in the zoo)
but is PARKING-LOT, not shipped. Immediate fresh-context pickup:_

- **🗣️ ZONOS-GATEWAY TTS — SHIPPED + ONLINE (irv-ml1), the R17 expressive winner.** Two pieces. (1) **Zonos
  engine** — native zonos2 server (`Zyphra/ZONOS2`, Apache), bare `python3` on irv-ml1 **:1920**, on the **3090**
  (operator moved it here off the retired omnivoice); streams float32 PCM @44.1kHz via `POST /tts/generate`;
  emotion = **embedding-direction conditioning (NOT tags)** + **clone-gated** (no-ops without a speaker ref);
  vendored copy kept **STOCK**. (2) **zonos-gateway wrapper** — OpenAI `/v1/audio/speech` facade over the native
  endpoint, **containerized** at `/opt/docker/compose/zonos-gateway/` (image `zonos-gateway:0.2.0`,
  `restart: unless-stopped`, reaches host Zonos via `host.docker.internal:1920`), **:8890**, default voice **Cora**
  (voices = `*.wav` baked into the image). Full **24-dial** expressive surface + presets
  (neutral/warm/excited/sad/intense/whisper) via `GET /v1/dials`; `response_format` pcm|wav. Repo
  `~/development/zonos-gateway` (v0.2.0, LOCAL git only). **In asset-engine catalog**
  (`docs/asset-engine/services.yaml`, id `zonos-gateway`, status experimental) → shows **online** (background poller
  auto-adopts the running container, NO VRAM gate, NO `/start`) → experiment at
  `http://10.250.50.70:8200/ui/stream-audition/zonos-gateway`. **gateway-chat** (ana-docker:8091) repointed DIRECT
  to it (OpenAI body, Cora, streamed, quotes joined not chunked). ⚠️ **NEVER expose the rep-penalty dials**
  (50/1.2/8 — LOAD-BEARING; OFF → 70s-silence footgun). Auto-memory `reference_zonos_tts_stack`. **PENDING
  close-outs:** (a) repoint LiteLLM `ext-tts` alias → the wrapper (generic hot-swap point; NOTE LiteLLM buffers
  audio → streaming needs a DIRECT wrapper hit, not through `ext-tts`); (b) revert vendored Zonos `api_server.py`
  OpenAI-endpoint patches to STOCK (rep-penalty + `_voice_to_speaker_id` + Cora reg; `.bak-*-20260710` on irv-ml1 —
  the wrapper made them redundant); (c) cosmetic: catalog `model.image` reads `local/zonos-gateway:0.1.0`, reality
  `zonos-gateway:0.2.0` — reconcile on next catalog touch (a resync bounces the live lab). Old bare-deploy dir
  `/home/lkraven/zonos-gateway` on irv-ml1 = idle cruft.

- **🔊 R17 TTS AUDITION — CONCLUDED (operator ranked live).** 3-model expressive audition
  (Chatterbox-fast / ZONOS2 / Higgs-v3) on irv-ml1's A6000 (ComfyUI taken down to free it). **Latency smoke**
  (`~/tts-audition/records/latency.csv`): Chatterbox TTFA 0.47–0.80s / RTF 0.28–0.38 (24kHz streamed — fastest,
  stays the low-latency front-end); ZONOS2 warm TTFA ~8s / RTF 2.79 (44.1kHz, clone-gated emotion); Higgs whole-file
  TTFA≈gen 2.6–2.8s / RTF 0.98 (NOT streamed — footnote, not comparable to the streamed two). **Outcome: Zonos
  productionized** for the expressive tier (see zonos-gateway above); **Higgs = parking-lot** (streams, room in the
  zoo, not shipped — Path-A in-process build preserved at `~/tts-audition/`: venv `venvs/higgs`, transformers 5.5.0,
  `harness/higgs_native.py`, Qwen3-4B backbone + baked codec; revisit if wanted). **Chatterbox-fast** stays the
  low-latency front-end. Protocol: brokkr-smithy R17 `tts-audition-protocol.md`.

- **🖼️ COMFYUI — v0.27.1 LANDED + comfy-dev-VALIDATED, now TAKEN DOWN (A6000 freed; comfy-dev PARKED).** The
  v0.27.1 bump stays LANDED (validated clean by comfy-dev, thread 01KX6D3C — 3-tier sweep 189 graphs / 105
  node-types, ZERO breakage, all 9 templates + smoke renders OK: Z-Image / FLUX.1-dev / Illustrious-SDXL /
  FLUX.2-GGUF / Qwen-edit sage-AttentionSelector / LTX i2v). ComfyUI is just **not RUNNING** — operator took it down
  to give the R17 audition the A6000. **Restart when comfy-dev un-parks.** Landed on the EXISTING **torch
  2.12.1+cu129, SageAttention 2.2.0 intact** (deliberately did NOT bump torch — the 2.13 bump was the mmartial
  boot-upgrade's ABI crash-loop cause, never an LTX requirement; **SETTLED = don't bump**). Mechanics: code
  `/worktank/comfyui/run/ComfyUI` (=/comfy/mnt/ComfyUI in-container), `docker exec` lands as uid **1025** → use
  `-u 1000` + venv python `/comfy/mnt/venv/bin/python` (venv owned lkraven:1000), `DISABLE_UPGRADES=true` pinned,
  NVIDIA_VISIBLE_DEVICES=1 (A6000). Rollback net `/worktank/comfyui/venv-snapshot-comfyui-0.24.1-20260710.tar`. LTX
  Phase-2 node-install = its own future thread (installs uid-1000).

- **📅 BIWEEKLY LANDSCAPE-SCAN CRON — SETTLED.** Live systemd --user timer on nh3-dev (next auto-run 2026-07-15
  09:00 PT), dedicated `brokkr-scan-dev` handle, notify = `post --to brokkr-smithy-dev` (Vuong ruled inbox-post,
  no phone-push). Fully validated end-to-end. Nothing owed; watch for a brokkr-scan-dev first-dwarf-arm routing
  hiccup flag on the 15th.

- **📬 althing:** a harness-tracked wake-listener was armed for comfy-dev's reply. **A /clear kills the monitor
  loop → the fresh session must re-arm (`/althing:monitor`)**; the 📬 banner surfaces new peer mail on next prompt
  regardless.

_Earlier (2026-07-09) context preserved below:_

_As of 2026-07-09 — RP-seat 3-seat inference stack still COMPLETE + SETTLED (gen + char-rp +
char-rp-reasoning, detail below). NEW this session: a **mOrpheus TTS voice pipeline** shipped
end-to-end (deployed on irv-ml1, voicing gateway-chat). Home-training dormant. Live state:_

- **⚠️ SUPERSEDED 2026-07-11: vllm-morpheus KILLED (operator: unimpressive); gateway-chat is now voiced by
  zonos-gateway (above), NOT mOrpheus. Block kept for the SNAC/clone-voice detail only.**
- **🗣️ mOrpheus TTS — PERMANENT STACK DEPLOYED (irv-ml1), voicing gateway-chat.** Off-the-shelf
  uncensored Orpheus TTS (`MrDragonFox/mOrpheus_3B-1Base_early_preview-v1-25000`; Llama-3.2-3B LLM
  → SNAC 24kHz audio). Canonical `stacks/mOrpheus/`; deployed at `/home/lkraven/morpheus/` on irv-ml1.
  **Two containers:** `vllm-morpheus` (engine — **bf16 REQUIRED** (FP8 breaks audio); **image PINNED
  `vllm/vllm-openai:v0.23.0`** (`latest` crashes on Ampere import); on the **3090** (A6000 is
  comfy-contended, spikes to ~41GB); `--enforce-eager` + util 0.32 ≈ 7.9GB) + `morpheus-tts` (CPU
  FastAPI — tokenizer + SNAC decode; `/tts` whole-clip WAV, `/tts/stream` windowed-chunk PCM stream,
  zero-shot cloning; CORS-enabled). **RTF ~1.0 end-to-end** (enforce-eager caps it; vLLM single-3090
  concurrency is near-linear to `--max-num-seqs 8` = 8× at 707 tok/s). **gateway-chat** (ana-docker:8091,
  the zero-dep `tools/gateway-chat.html`) auto-voices assistant **quoted** dialogue: chunk by QUOTED
  SECTION (prosody), Web-Audio streaming player (TTFA ~0.8s, shared clock, resume-on-gesture), 🔊 sidebar
  toggle + endpoint/voice fields. **Clone voices** (drop `<name>.wav` + `<name>.txt` in the voices dir →
  `voice="<name>"` clones it): `baddy` (native speaker), `beatrice`, `whisper` (kokoro **af_nicole**, a
  genuine whisper voiced 0.24; mOrpheus partially re-voices it → clone voiced 0.42, breathy not pure).
  Honored tags = learned text-patterns (canonical Orpheus laugh/chuckle/giggle/sigh/groan/gasp/yawn/cough/
  sniffle + NVV pant/grunt/kiss/moan); agent voicing prompt at `stacks/mOrpheus/agent-voice-prompt.md`.
  **OPEN:** whisper re-voices (checkpoint limit, not the reference); throwaway audition `:8210` +
  `/home/lkraven/orpheus-audition/` still up on irv-ml1 (teardown pending, ~6.3G weights moved out already);
  production concurrent-gen + a SNAC-decode worker pool NOT built (CPU decode is the scale bottleneck, not gen).

- **SERVING TOPOLOGY, ana-ml2 GPU0 (co-resident), served via the `qwen36-27b-aeon` + `ms32-24b-angel` compose stacks:**
  - **gen (:8015) = `qwen36-35b-a3b-heretic-nvfp4` — LIVE + GOOD.** Off-the-shelf NVFP4 of
    `llmfan46/Qwen3.6-35B-A3B-uncensored-heretic-Native-MTP-Preserved-NVFP4-Experts-Only` (MoE 256e/8-active =
    qwen3_5_moe, vision, GDN-hybrid; **modelopt** format → `--quantization modelopt`; vision bf16; 24G at
    `/tank/aimodels/qwen36-35b-a3b-heretic-nvfp4`). UNCENSORED (writes brutal fiction think-off, no system prompt).
    "Blathers" → needs adequate max_tokens (thinking-on looks EMPTY under ~600 tok, fine at 3k — NOT broken).
    General-assistant seat. Served by `/opt/docker/compose/qwen36-27b-aeon/` (`.env` repointed: `AEON_GEN_MODEL`,
    `AEON_GEN_QUANT=modelopt`, `AEON_GEN_GPU_MEM_UTIL=0.40`; the `--quantization` line is now
    `${AEON_GEN_QUANT}`-parameterized). Served-names `qwen3.6-27b-aeon`/`-thinking` (gateway gen/gen-reasoning stay
    transparent). **util 0.37 (~35G; dropped from 0.40 on 2026-07-08 to fund char-rp 128K — the RP seats are now co-resident, ~4.4G GPU0 margin).** AEON + the intermediate Pantheon-27B
    serves are RETIRED.
  - **char-rp (:8016) = `TheDrummer_Magidonia-24B-v4.3-Q6_K` GGUF — LIVE + EXCELLENT.** Magistral (Mistral)
    dark-romantasy RP tune via llama.cpp (`char-rp-gguf` stack, container `llama-charrp`). NON-thinking PROSE seat:
    elite literary prose, zero refusal on dark/explicit scenes, ~65 tok/s, tight POV/instruction adherence
    (live-tested). Replaced the broken Angel NVFP4. Alt prose model (`.env` swap `CHARRP_MODEL`):
    `MS3.2-PaintedFantasy-v4.1-24B` (more literary flair, looser POV). Both GGUFs pre-pulled at `/tank/aimodels/llm/rp/`.
  - **char-rp-reasoning (:8018) = `Qwen3.5-27B-Deckard-PKD-Heretic-Uncensored-Thinking.i1-Q5_K_M` GGUF — LIVE
    (A/B WINNER 2026-07-08, REPLACED RpR-v4).** DavidAU creative (PKD) tune on Qwen3.5-27B (container
    `llama-charrp-reasoning`). Native Qwen3.5 template → `--reasoning on` managed CoT SURFACES in `reasoning_content`,
    content stays clean prose, `--reasoning-budget 400` caps it; **DRY server-side** (sampler order = dry-after-temp)
    tames looping. A/B: **0/30 loops + 0/30 refusals**, ~57 tok/s. Runs on the base llama-swap b8840 image (Qwen3.5).
    Best-of-breed-per-seat (NOT the same model as char-rp).

- **🦄 RP-SEAT UNICORN — RESOLVED + DEPLOYED (2026-07-08).** char-rp = **Magidonia-24B-v4.3** (Magistral prose,
  65tps); char-rp-reasoning = **Deckard-PKD (Qwen3.5-27B)** (managed reasoning + DRY, ~57tps; A/B winner over RpR-v4 — see re-A/B note below). Both GGUF via
  llama.cpp (`char-rp-gguf` stack, ana-ml2 GPU0, ~86/97G co-resident with gen, ~11G margin). Canonical stack in repo
  `stacks/char-rp-gguf/`; gateway rewired (`char-rp`→:8016, `char-rp-reasoning`→:8018, Mistral/QwQ samplers, dropped
  the Qwen `enable_thinking` kwarg). **KEY FINDINGS:** (a) no single dense 24-32B is BOTH an elite non-thinking prose
  seat AND a clean *managed*-reasoning seat on llama.cpp → best-of-breed per seat; (b) Magidonia's Magistral `[THINK]`
  discipline is loose (won't close `[/THINK]` on substantive reasoning → prose bleeds into reasoning, content empties);
  Cydonia-R1's `<think>` is emergent (llama.cpp can't manage/cap → runaway CoT never reaches prose); QwQ's template
  opens `<think>` natively → llama.cpp manages+caps it; (c) **Pantheon-Reasoning-27B stays REJECTED** (re-censors in
  `<think>`; RpR-v4's abliterated-reasoning is the fix); (d) reasoning now SURFACES in `reasoning_content` (fixes the
  old AEON trace-not-surfacing gap). One-model fallback (Magidonia both, lighter reasoning) documented in the stack
  header/README. Requirements met: prose#1, ≥50tps#2, low-refusal#3, dense#4, GGUF-not-Ollama#5, fit-GPU0#6, thinking#7.
  Candidate GGUFs also on disk for A/B: Cydonia-R1-24B-v4.1, PaintedFantasy-v4.1-24B, RpR-v4 Q6_K.
  **REASONING-SEAT RE-A/B (2026-07-08, later — RpR→Deckard):** operator wanted a reasoning model that TAKES DRY
  (RpR forbids rep/DRY → 1/30 loop tail). Full A/B on brokkr's 30-prompt D1 suite (content-only, slop-scored):
  **Deckard-PKD (Qwen3.5-27B) WON** (0/30 loops, 0/30 refusals, clean) → NOW the char-rp-reasoning seat.
  RpR-v4: 0 refusals but 1/30 loop (no-DRY). **Pantheon-Reasoning-27B: 7/30 explicit refusals** (DeepSeek-distilled
  re-censor IS real across the batch, milder than feared; NOT wholesale-rejected) — kept on disk as alt.
  Snowdrop-v0.5-Type-S + Gembrain-31B (Gemma-4): FLOORED — llama.cpp can't do MANAGED reasoning on them (Snowdrop's
  ChatML template has no `<think>`/`enable_thinking` hook; Gemma-4's reasoning parser splits content wrong). GATE for a
  llama.cpp reasoning seat = STOCK template natively opens `<think>` or has `enable_thinking` (Qwen3.x/QwQ do; ChatML +
  Gemma-4 don't). **INFRA:** llama-swap b8840 image can't load Qwen3.6/Gemma-4 archs → use
  `ghcr.io/ggml-org/llama.cpp:server-cuda` (newer, pulled on ana-ml2) for those; Deckard (Qwen3.5) runs on b8840.
  **brokkr frozen-scorer CONFIRMED (median composite, content-only; lower=cleaner):** Deckard **2.176** (0 loop/0
  refuse — DEPLOYED, big win over RpR **3.716** + its loop-tail); Pantheon-Reasoning **1.383** (cleanest prose of the
  field — beats even Magidonia char-rp 1.774 — BUT 7/30 explicit refusals → rejected: clean-but-refuses loses to
  clean-and-uncensored). **MEMORY-LAYOUT note:** Deckard (Qwen3.5-27B) is GDN-hybrid → only **16 KV-caching layers** →
  KV is TINY (1.4G @ 40K vs Magidonia's 10.9G @ 128K, 40 dense layers); Deckard native ctx = 256K, so the reasoning
  seat's ctx scales nearly free. **Deckard BUMPED to full 256K (262144) 2026-07-08** (KV 8.7G q8_0). GPU0 layout now:
  gen ~35G (256K/16-seq/util0.37), char-rp Magidonia ~30G (128K/4-slot), char-rp-reasoning Deckard ~28G (256K/4-slot),
  **~4G free** (all static allocations → stable, no OOM). **Canonical Deckard RP-reasoning samplers CONFIRMED by dvalin 2026-07-08**
  (thread 01KX1Y7P): the live empirical set IS canonical — temp1.0/top_p0.95/top_k40/min_p0.05, NO presence/rep
  penalty, DRY0.8 server-side (base1.75/len2, dry-after-temp), reasoning-budget400. Delta from card base-thinking:
  top_k20→40, min_p0→0.05, presence1.5→0, DRY-on. Tuning ladder: flat prose→min_p0.08; loops→DRY0.9; over-damped→
  DRY0.6/off. Do NOT import RpR/QwQ rules (QwQ hated DRY; Qwen3.5 benefits from DRY over rep_penalty).
  **MAX CONTEXT (2026-07-08):** char-rp **128K** (Magidonia FULL native 131072), char-rp-reasoning **40K** (QwQ

  so its 4.74×→3.66× concurrency-at-256K cut is invisible). GPU0 ~93/97G, **~4.4G margin** (gen fixed-util +
  static KV → stable, won't OOM). 64/50 tps. `kv_unified` → a single conversation gets the FULL n_ctx (4 slots
  share the pool, not a /4 split). Tunables: CHARRP_CTX / CHARRP_REASONING_CTX / *_KV_TYPE / AEON_GEN_GPU_MEM_UTIL.

- **NVFP4/GGUF quant tooling (proven, on ana-ml2):** `/tank/aimodels/quant-work/` — `nvfp4_quant.py`
  (llm-compressor, MoE-aware `load_quantizable_moe`, Mistral-tuned ignore) + `.venv`; `qwen35_vision_nvfp4.py`
  (llm-compressor + qwen ignore + `trust_remote_code` + a torchvision-gate bypass). ModelOpt path:
  `/home/lkraven/nvfp4-quant/.venv-mopt` (modelopt 0.44) + `mopt_w4a16.py` (= `mtq.quantize` + `export_hf_checkpoint`
  → modelopt format w/ `hf_quant_config.json`). Downloads via a detached vLLM container running
  `huggingface_hub.snapshot_download` to `/tank/aimodels/<name>-{bf16,nvfp4}`. **Gotchas:** llm-compressor
  `save_compressed` DROPS tokenizer/chat/preprocessor files → stage from the bf16 source; the qwen ignore keeps
  `re:.*visual.*` + `re:.*linear_attn.*`(GDN) + lm_head + embeds + `mlp.gate`(router) bf16.

- **🪦 T1 / home-trained LoRA — DORMANT (pivoted to off-the-shelf).** DPO came back slop → operator killed
  home-training (2026-07-08). ONLY this project dormant; LEAVE arbo's LoRA-worker (irv-ml1 :8203), ALL /tank models,
  and every other project ("ritual seppuku" otherwise). **Revival map:** adapters `data/spike/{sft,dpo}_adapter`,
  harness canonical v0.0.44, full saga in Recent decisions + mtf-dev auto-memory; aeon-trainer image left (28G).
  mtf-dev stood down. (Detailed 2026-07-07 hot-swap findings preserved below + in Recent decisions.)

_Earlier (2026-07-07):_

- **T1 SFT COMPLETE (AEON-27B E-RP LoRA) — adapter banked, but BLOCKED on hot-swap serving.** SFT ran
  clean on ana-ml2 GPU0 (all-TRL torch-GDN, batch1/accum8/GC-off, 1 epoch, ~9h @ 0.25 s/s steady, final
  loss 2.445); adapter at `ana-ml2:~/model-training-forge/data/spike/sft_adapter` (124MB, r16 α32, targets
  `self_attn.q/k/v/o_proj` + `linear_attn.in_proj_qkv/out_proj`, NO `in_proj_z`). DPO leg deferred (needs
  mergekit resolved + on-policy `rejected` regen). **THE WALL: the adapter is INERT on the vLLM NVFP4
  hot-load** — loads HTTP 200 but zero deltas reach inference (vLLM 0.24.0 qwen3_5 LoRA-APPLICATION silent
  no-op; upstream #47639 open / fix PR #47640 open / regression from #37912). Proven quant-agnostic (NVFP4
  AND FP8 both inert) AND adapter-format-agnostic (separate-key `sft_adapter_zc` loads clean via vLLM's
  allowlist but inert; the fused-key rekey rejected outright). The #47640 guard-patch overlay did NOT fix
  it. **HARD REQUIREMENT (operator): hot-swappable or ABANDON — merge is NOT a solution now** (static;
  reserved for a later RP-quant track only).

- **HOT-SWAP — SGLang zc smoke + 2-line patch RAN (2026-07-07). PARTIAL PROGRESS: patch cleared startup
  validation + self-attn LoRA loads end-to-end, but GDN in_proj hit 2 MORE name-routing gaps → NOT a
  one-line fix. MERGE RECOMMENDED (operator's call, pending).** Ran `sft_adapter_zc` on SGLang 0.5.13 bf16
  (`--lora-target-modules all --max-lora-rank 16 --lora-paths t1=/adapters/sft_adapter_zc`, GPU0, gen+rp
  stopped for the smoke then restored). Base weights loaded clean; self-attn q/k/v/o normalized + accepted
  fine. **Died at `lora_manager.init_lora_shapes` with a NAME-VALIDATION `ValueError` (NOT the feared
  in_proj_qkvz shape-assert):** adapter's `in_proj_qkv`+`in_proj_z` "not included in --lora-target-modules
  [...in_proj_qkvz...]". **ROOT CAUSE (pinned):** `srt/lora/utils.py:235 get_normalized_target_modules` uses
  a HARDCODED `params_mapping` dict that maps `q/k/v_proj→qkv_proj` (why self-attn works) but OMITS
  `in_proj_qkv→in_proj_qkvz` + `in_proj_z→in_proj_qkvz`; it does NOT consult the model's
  `packed_modules_mapping` (which DOES declare `"in_proj_qkvz":["in_proj_qkv","in_proj_z"]` at
  `models/qwen3_5.py:1010`). Everything else is ALREADY in place: `get_hidden_dim("in_proj_qkvz")` IS
  implemented in the model class (`:1040`, → `(hidden_size, key_dim*2+value_dim*2)`; the "utils NotImplementedError"
  was only the DEFAULT); `get_stacked_multiply("in_proj_qkvz")=4` in the utils default dict; base-weight
  `stacked_params_mapping` fuses `in_proj_qkv→shards(0,1,2)`,`in_proj_z→shard 3`. **PATCH APPLIED + RE-SMOKED
  (bind-mounted a patched utils.py overlay into the container):** the 2-line add cleared `init_lora_shapes`;
  server came up "fired up and ready", LoRA kernels compiled (K=16384 in_proj_qkvz expand + K=6144 in_proj_z
  shrink — B-side math right per mtf-dev), **self-attn loaded end-to-end** ("loaded weights for [o_proj,out_proj,
  qkv_proj]"). **BUT GDN in_proj died at TWO MORE name-resolution points (name-routing, NOT shape/intractable):**
  (1) adapter-load SKIPPED 192 in_proj_qkv/in_proj_z weights ("did not match any target module [...in_proj_qkvz...]");
  (2) inference buffer-fill `utils.py:300 get_target_module_name` RAISED — SUBSTRING match, `in_proj_qkvz` ⊄
  `...in_proj_qkv.` and `qkv_proj` ⊄ it → "Cannot find target module name for ...in_proj_qkv.lora_A.weight" →
  HTTP 500 + scheduler killed. So SGLang's GDN LoRA name-routing is incomplete in ≥3 code paths (fixed 1/3).
  **FINISH LINE (if ever revived):** teach `get_target_module_name` + the load-consolidation the
  `in_proj_qkv/in_proj_z→in_proj_qkvz` map (mirror qkv_proj, which works E2E), THEN mtf-dev's buffer
  shard-placement (0,1,2)+3 question goes live again (still UNPROVEN, deepest step). Per operator's "one
  targeted fix else merge" rule → this is multi-point, NOT one fix → MERGE recommended. mtf-dev replied +
  loop closed (thread 01KWZDZFYN…). (SGLang GENERIC image still can't
  LOAD our NVFP4 checkpoint — bf16-only smoke.) Adapter variants: `sft_adapter` (separate), `sft_adapter_zc`
  (separate + zero `in_proj_z`, the canonical one — THIS smoke), `sft_adapter_fused` (fused — wrong), plus
  `sft_adapter_attnonly`. All at `/home/lkraven/model-training-forge/data/spike/`.

- **MERGE FALLBACK — primed (~2-3h) if hot-swap is fully abandoned.** peft merge_and_unload (~20min, LOW
  wall — separate keys merge directly, no rekey) → sanity greedy-diff (finally reveals if the ~10h training
  is any good — we've NEVER seen the LoRA apply) → ModelOpt NVFP4 re-quant of the merged bf16 (~1-2h,
  MEDIUM-HIGH wall = the GDN-hybrid requant + calibration + verify GDN modules quantize) → serve as plain
  base (no `--enable-lora`). Static, NOT hot-swappable.

- **comfy-dev in-arbo LoRA-training worker — DONE (all phases, this session).** Built/deployed the worker
  (`services/lora-training-worker/`, irv-ml1 `0.0.0.0:8203`, runs as llmuser, fixed-invocation sd-scripts,
  systemd, elway deploy playbook; commits 888ba6a→b617a8b). Phase 1 first real train SUCCEEDED (Sindra
  fast/lean). Phase 2 publish-step (`published_lora_name` + optional `train_id` field). Phase 2.5 GC
  contract (shape A: `GET /published-loras` + `POST /gc/published {train_ids}`) CONFIRMED — worker impl
  DEFERRED to after the T1 hot-swap work. auto-memory `reference_lora_training_worker`.

- **Serving state (SUPERSEDED — see top; AEON retired 2026-07-08):** during the T1 work, AEON gen (:8015) +
  char-rp (:8016) NVFP4 were HEALTHY, stopped/restored for hot-swap smokes via `docker start vllm-aeon-gen
  vllm-aeon-rp`. Now replaced: gen = 35B-A3B heretic, char-rp = (broken Angel, being replaced).

- **worldtree-dev vh/pypi read token** delivered (bifrost==1.1.0 pin, #349); dedicated read:package token
  at `nh3-dev:~/.config/gitea-tokens/vh-pypi-read.txt`. The over-scoped write:package token the operator
  pasted was revoked + verified dead.

- **Backups — STILL OPEN:** rotate the 5 disclosed rest-server creds (operator, offline); confirm
  esh-vm-db's resticprofile includes DB dumps. `docs/runbooks/backups.md`.

- **Standing / parked:** inert `mood.decay_rate`/`stale_hours` keys in deployed WT config; Mac Pro
  migration (hw-gated); R22 gateway-key at `/home/lkraven/.r22-gateway-key` (mode 600, paid GLM, do NOT
  delete); Deckard staged on ana-ml2 as T1's writing benchmark; `/books` transient NFS mount on nh3-dev;
  **dvalin sampler re-tune pass** for char-rp / char-rp-reasoning once they accumulate live Worldtree/ST
  character-role traffic (dvalin offered 2026-07-08 to do a follow-up after more live sessions; the current
  paper defaults + 2-prompt A/B are the starting point — real long-session usage is where repetition/drift
  surfaces; re-open thread `01KX1DS6…` to take them up on it).

- **Worldtree config-propagation (reference):** demo+personal bind-mount config from
  `/opt/worldtree{,-personal}/config` (infra-ops-deployable, byte-identical from canonical); reload via
  `docker restart <container>`, NEVER `compose up` (stale-`:latest` footgun). Role registry loaded ONCE +
  CACHED at startup → a bind-mount `model_roles.yaml` change needs a restart; pre-stage BEFORE the
  activating deploy's restart. config REMOVALS are NOT backward-compatible with the running image.

## Recent decisions

- `[2026-07-10]` **Heimdall grant: ratatoskr `affect.full` on PERSONAL Worldtree (operator-approved, worldtree-dev
  R34-v1 request).** Added allow-rule `ratatoskr-affect-full-allow` to `/opt/worldtree-personal/config/policies.yaml`
  (`principal.user_ids:["ratatoskr"]`, action `affect.full`, resource `*`, effect allow), mirroring the #347
  `session-history-write-ratatoskr` rule exactly + placed right after it. **WHY user_ids-based (not tier):** ratatoskr's
  personal key is the minimal **readonly-admin** observability tier, which is NOT in the tier-based
  `affect-render-baseline-allow` (anonymous/user/free/pro/admin) → needs an explicit user_id grant, same as #347.
  R34-v1 (b46, committed UNPUSHED) gates `affect.emit` `dominant_emotion` egress by exposure ceiling (affect.full|safe
  → present; neither → null); this grant keeps ratatoskr's view alive across the b46 deploy. Surgical exact-string
  insert (preserves comments), backup `policies.yaml.bak-pre-affectfull-20260710`, validated via the CONTAINER's own
  yaml parser (35 rules, +1, payload confirmed). **NOT restarted — deliberate:** rule is on the bind-mount (shadows
  baked), INERT until b46 gating ships, so the b46 CI/CD deploy restart activates it (no live-session blip now). Demo
  untouched (personal-only per key scope). Replied to wt-dev (thread 01KX6DB3…) offering an immediate restart if they
  want it live for pre-b46 testing. See [[reference_corviduo_dev_emergency_ops]].

- `[2026-07-10]` **ComfyUI v0.27.1 SUCCESS on irv-ml1 (operator-confirmed execute-now) — landed on torch 2.12.1,
  SageAttention preserved, crash-loop AVOIDED.** The prior attempt (entry below) crash-looped because a torch
  2.12.1→2.13 bump broke SageAttention's ABI. This time I checked `git diff v0.24.1 v0.27.1 -- requirements.txt`
  FIRST and found **core v0.27.1 leaves `torch` UNPINNED** → the version bump does NOT require torch 2.13 (that came
  only from the mmartial boot-upgrade). So: `git checkout v0.27.1` (clean tree) → `pip install -r requirements.txt`
  as **uid 1000** with a **torch-pin constraint file** (torch/vision/audio pinned to current +cu129) to block any
  transitive bump → torch stayed 2.12.1, SageAttention 2.2.0 untouched. Added decord 0.6.0 (fixed SAM3Segment).
  `docker restart comfyui` → healthy, `/system_stats` comfyui_version=0.27.1, "Using sage attention", HTTP 200, DB
  migrated 0003→0004. Reported the divergence to comfy-dev (thread 01KX6D3C…, reply pending) + asked whether LTXV 2.3
  needs a separate torch-2.13 follow-up (their domain; Krea-2's ≥0.25 need is met by 0.27.1). **LESSON: before a
  mmartial ComfyUI version bump, `git diff <old> <new> -- requirements.txt` — if torch is unpinned, bump the CODE
  without touching torch (constraint-pin it) and compiled exts (SageAttention) survive. `docker exec` lands as uid
  1025(comfytoo), not 1000 — use `-u 1000` + the venv python `/comfy/mnt/venv/bin/python`.** See
  [[reference_irv_ml1_comfyui_mmartial]].

- `[2026-07-10]` **ComfyUI 0.25.x bump on irv-ml1 ATTEMPTED → FAILED → ROLLED BACK (snapshot saved it).** comfy-dev
  requested (Vuong-authorized) bumping the irv-ml1 `comfyui` stack (mmartial image, `/opt/docker/compose/comfyui/`,
  0.24.1) to 0.25.x for Krea-2 + LTXV 2.3. **TWO FINDINGS: (1) `DISABLE_UPGRADES=false`/USE_PIPUPGRADE bumps the
  VENV (torch 2.12.1→2.13.0 + deps) but does NOT advance the ComfyUI CODE checkout** (`/comfy/mnt/ComfyUI` =
  `/worktank/comfyui/run/ComfyUI` stayed 0.24.1 — pinned/detached git, comfy-dev's domain). **(2) the torch bump
  broke SageAttention** (2.2.0 `_fused.so` undefined-symbol `c10::impl::cow::materialize_cow_storage` vs torch
  2.13.0) → `--use-sage-attention` (REQUIRED launch flag in COMFY_CMDLINE_EXTRA) crash-looped ComfyUI. Net: broke
  the working state, zero 0.25.x payoff. **ROLLBACK WORKED**: pre-bump 16G venv snapshot
  `/worktank/comfyui/venv-snapshot-comfyui-0.24.1-20260710.tar` restored (torch 2.12.1 + working SageAttention),
  re-pinned DISABLE_UPGRADES=true, recreated → healthy on 0.24.1, serving :8188. Broken venv parked at
  `/worktank/comfyui/run/venv.broken-torch213-20260710`. **CORRECTED PATH (sent comfy-dev, thread 01KX655V):**
  comfy-dev git-advances the ComfyUI checkout to 0.25.x + reqs → I handle the torch bump + SageAttention
  rebuild-against-2.13.0 + re-pin (snapshot stays as the net). **LESSON: mmartial `DISABLE_UPGRADES` gates ONLY
  the venv pip-upgrades, NOT the ComfyUI git checkout; a torch bump breaks compiled exts (SageAttention) →
  rebuild-after is mandatory.** Bump BLOCKED pending comfy-dev's git-advance. Stack: A6000 (NVIDIA_VISIBLE_DEVICES=1),
  lkraven-owned compose+venv (uid 1000, no sudo needed), COMFY_CMDLINE_EXTRA OOM flags preserved.

- `[2026-07-10]` **Biweekly open-weight-releases scan cron set up for brokkr-smithy (Vuong-authorized).** Durable
  systemd **--user** timer on nh3-dev (`brokkr-landscape-scan.timer`, OnCalendar `*-*-01,15 09:00:00`
  America/Los_Angeles, Persistent=true; linger on) → `.service` → wrapper `~/.local/bin/brokkr-landscape-scan.sh`
  runs headless `claude -p "$(cat ~/.config/brokkr-landscape-scan/prompt.txt)" --dangerously-skip-permissions` in
  `~/development/brokkr-smithy` (ALTHING_HANDLE=brokkr-smithy-dev; **explicit PATH** — the --user minimal-PATH
  footgun; per-run logs `~/.local/state/brokkr-landscape-scan/`). Prompt = brokkr's payload verbatim (LLM/image/TTS
  new-release sweep → ranked synthesis → commit+push+notify). VALIDATED: git-push non-interactive (BatchMode
  ls-remote to gitea, passphraseless key — no agent), headless claude auth (READY smoke). VALIDATED END-TO-END 2026-07-10 (manual run, exit 0):
  web-sweep→synthesis→commit `2ed2f29`→PUSH of scan #2 (open-weight-releases-2026-07-24.md); triaged dwarf input +
  caught baseline errors, quality strong. **HANDLE-COLLISION caught+FIXED** — the headless scan shared handle
  brokkr-smithy-dev with the LIVE session + raced its inbox (eitri's dwarf-reply got stolen by the live monitor);
  registered a dedicated **brokkr-scan-dev** handle (`add-handle`, driver=none) + repointed the wrapper + rewired
  step-5 notify → `althing-cli post --to brokkr-smithy-dev` (NO vuong althing handle exists — confirmed). model=default
  + `--max-turns 80`. First run under the new handle = 7/15. Off-cycle 07-24 doc is a validation artifact (scheduled
  1st/15th runs date to their own run-date, no collision) — operator naming-convention call pending.
  **NEXT AUTO-RUN 2026-07-15 09:00 PDT.** Manual validation/first run = `systemctl --user start
  brokkr-landscape-scan.service`. Open w/ brokkr (thread 01KX63G6): confirm notify-Vuong handle/mechanism + session
  handle + model/turn-cap. **NEXT brokkr task (operator-sequenced after this): TTS audition env** — Higgs-TTS-3 +
  ZONOS2 + Chatterbox baseline, TTFA/RTF + blind-A/B web-listen (thread 01KX6371; needs GPU-placement + HF-token
  feasibility pass first; brokkr delivers the prompt set after the env's up; protocol doc in brokkr-smithy repo).

- `[2026-07-09]` **Two parked items closed: phantom `qwen3.6-35b-a3b` alias VERIFIED already-gone; ana-docker
  docker log-cap SOLVED no-bounce.** (1) **Phantom**: absent from `/v1/models` + `/model/info` (config+DB
  registry), zero litellm log refs — the parked "400s in /v1/models" note was STALE (already cleaned in the
  2026-07-08 gen repoint to `-heretic`); bare token survives only in 2 config COMMENTS (lines 76/80). Nothing to
  remove. (2) **Log-cap**: running containers were UNCAPPED (182M json-logs, top offender 59M) because
  daemon.json's `max-size 10m/max-file 3` only applies to containers CREATED AFTER a daemon restart — it never
  reaches already-running ones. No-bounce fix = `/etc/logrotate.d/docker-containers` (**copytruncate** — dockerd
  opens json-logs `O_APPEND` so truncate-in-place resets cleanly, no sparse-file corruption; `size 10M`,
  `rotate 3`, `compress`, `su root root`), auto-picked-up by the daily `logrotate.timer`. Force-ran + gzipped the
  frozen `.1` archives → **182M → ~55M** (44M active + 11M gz), every container kept its multi-week uptime
  (zero bounce, verified). **LATENT FOOTGUN FLAGGED (not yet fixed, operator's call): daemon.json declares
  `live-restore:true` but the RUNNING daemon has it FALSE** (daemon.json was edited after the last daemon start,
  never reloaded) → the NEXT `systemctl restart docker` / crash / pkg-upgrade **bounces ALL ana-docker containers
  once**. Fix WITHOUT a bounce = `systemctl reload docker` (SIGHUP loads live-restore into the running daemon;
  log-opts are NOT SIGHUP-reloadable, which is why logrotate — not the daemon cap — is the enforcer for running
  containers).

- `[2026-07-09]` **granite→gen `memory_extractor` bind host-synced on demo+personal Worldtree (Vuong-directed,
  #335 Slice-4).** Changed `model_roles.yaml` memory_extractor `binds.catalog_id` `summarizer`→`gen` (overrides
  intact: thinking:false/temp0/8192) on BOTH `/opt/worldtree{,-personal}/config`; `memory_distiller` left on
  `summarizer` (range-scoped sed `/memory_extractor:/,/memory_distiller:/` — the naive global replace would've hit
  both); backups `*.bak-preqgen-20260709`; validated via each container's OWN yaml parser. **DEMO LIVE on gen**
  (b43 `d501e516732d` auto-deployed mid-edit + its restart RACED my edit by ~2min → I restarted
  `worldtree-worldtree-api-1` to activate; healthy, live process resolves memory_extractor=gen). **PERSONAL
  NOW LIVE on gen too** — Vuong authorized the restart (via wt-dev); restarted `worldtree-personal-worldtree-api-1`
  after a PRE-FLIGHT that ran the app's OWN `load_model_roles()` (`core/llm/roles.py:121`) against the synced config
  INSIDE the running `c9986cd` container: `gen` in catalog, all 9 roles resolve, no `DanglingBindingError` → proven
  safe on the OLDER image BEFORE touching it (model_roles-delta-alone clean; no full-config-set sync needed).
  StartedAt 20:50:55Z, healthy, resolves gen. **BOTH instances live on gen.** **LESSON:
  the bind-mount `/opt/worldtree*/config` SHADOWS the baked `/app/config-defaults/` → the deploy alone never
  updates the ACTIVE config; the host edit is required AND a restart activates it (role registry cached at boot) —
  pre-stage BEFORE the deploy's restart or you race it.** FOLLOW-UPS (non-blocking): (a) `memory.extractor.user_pass`
  parity block → self-serve from the b43 baked `defaults.yaml` (pydantic-default no-op); (b) stale `gen` provider
  description (Mistral-Small-4 → qwen3.6-35b-a3b-heretic) → wt-dev owns the REPO-side `providers.yaml` fix
  (operator's call — NOT purely cosmetic: the gen/dialogue + classifier entries carry Mistral-Small-4 SAMPLING
  defaults that drive mask/lofn/forseti/mimir dialogue, so wt-dev re-validates for qwen), host cosmetic sync pairs
  when it deploys. Gave wt-dev the VERIFIED canonical 4-alias set (backends+samplers read from the LIVE gateway
  config, not the doc); corrected `docs/pfi/model-sampler-defaults.md` seat 4 (had lagged QwQ-RpR-v4 → Deckard-PKD;
  live gateway was always Deckard). Operator SCOPED IN the character-RP re-point (2026-07-09):
  character→char-rp / thoughtful-character→char-rp-reasoning (character-rp per wt-dev's role semantics), moving
  character RP off the GENERAL qwen onto the dedicated Magidonia/Deckard seats. Relayed to wt-dev w/ the mapping
  principle + a SAMPLER-OVERRIDE warning (DROP character-rp's old temp0.75/top_p0.85 overrides — carried onto the
  dedicated seats they'd clobber the canonical RP tuning DOWNWARD) + ratatoskr-reach note (role call is transparent
  but Magidonia/Deckard quality/latency differs from gen). DONE 2026-07-09: wt-dev committed 5d4fa4a (v1.0.0b44,
  UNPUSHED — operator drives push); operator directed host-ahead-of-push, so I sourced BOTH config files directly
  from that unpushed commit (local `~/development/Worldtree` checkout — capital W; `git show 5d4fa4a:config/…`) +
  mirrored VERBATIM to `/opt/worldtree{,-personal}/config` on demo+personal, paired-pre-flighted via the app's
  `load_model_roles()` (no DanglingBinding), restarted both → LIVE: character→char-rp, thoughtful-character +
  character-rp→char-rp-reasoning, memory_extractor→gen preserved. Backups `*.bak-prerp-20260709`. context_window
  VERIFIED (llama.cpp /props + char-rp-gguf `.env`): char-rp **131072**, char-rp-reasoning **262144** (gave wt-dev
  to patch the repo from its interim 32768). **HOST AHEAD of repo-remote until the operator pushes 5d4fa4a** (baked
  config converges with the bind-mount on push+deploy). GOTCHA: demo≠personal — PERSONAL was already partly
  re-pointed (2026-07-06 AEON-era character→char-rp) so its delta was mostly stale-AEON-descriptions→Magidonia/Deckard
  + character-rp + stripping personal's char-rp `default_params` temp0.7/top_p0.8 that CLOBBERED the gateway RP tuning
  downward; DEMO had no char-rp catalog entries at all (b44 adds them). Diffed each instance vs b44 before applying
  (both deltas = expected changeset only, nothing instance-specific clobbered). wt-dev PATCHED the context_window in **b45/3384a37**
  (char-rp 131072, char-rp-reasoning 262144). BUMPED HOST-AHEAD on both instances (operator-directed 2026-07-09):
  mirrored b45's providers.yaml → `/opt/worldtree{,-personal}/config`, restarted, verified LIVE (char-rp ctx
  131072, char-rp-reasoning 262144, bindings intact); backups `.bak-b44interim-20260709`. HOST now = **b45
  canonical** (providers.yaml) + b44 (model_roles unchanged b44→b45). STILL PENDING: (1) operator's batched push
  of **b44+b45** (`5d4fa4a`+`3384a37`) to converge the repo-remote — host is ahead, no fork; (2) user_pass parity
  block (defaults.yaml — NOT in either, separate). Threads `01KX3SGH`/`01KX48QP` (worldtree-dev),
  monitor armed. See [[reference_corviduo_dev_emergency_ops]].

- `[2026-07-09]` **mOrpheus TTS off-the-shelf voice pipeline SHIPPED end-to-end (irv-ml1) + wired into
  gateway-chat.** Full arc (commits): gen served-name honesty rename aeon→qwen3.6-35b-a3b-heretic (99a4a17,
  vLLM served-name + litellm refs, so /v1/models + spend-logs name the real model); permanent 2-container stack
  (01eedd8); gateway-chat auto-voice quoted dialogue (c948013); streaming decode TTFA 4.5s→0.8s (da76829);
  max_tokens 1200→2400→3500 with a context-clamp (f363fe6, 0655a37 — long lines were clipping at 14.6s, and
  `repetition_penalty` 1.1 is LOAD-BEARING: at 1.0 the model never stops); AudioContext resume-on-gesture
  no-sound fix (033f368); pre-chunk by QUOTED SECTION not sentence for prosody (a1f3023→f295cc1); staged clone
  voices baddy/beatrice/whisper (0655a37 + runtime .wav/.txt in the voices dir); agent voicing prompt (a573514).
  **Load-bearing config, all encoded in stacks/mOrpheus/: bf16 not FP8, image v0.23.0 not latest, GPU=3090 not
  A6000, rep_penalty 1.1.** Serving-viability confirmed: vLLM concurrency near-linear to 8× (707 tok/s).
- `[2026-07-09]` **granite→gen memory_extractor bind GREEN-lit for worldtree-dev (Worldtree #335 Slice 4).**
  Answered their VRAM/concurrency headroom check: gen (qwen 35B-A3B heretic) has ample headroom for ~2 bursty
  idle-triggered extractor calls (fixed 0.37 util; KV pool runs 0-2%; --max-num-seqs 16, near-linear batching).
  Corrected their stale "gen = Mistral Small 4 / 119B-6B" belief (gen IS the qwen 35B-A3B heretic since 2026-07-08).
  **This bind is INDEPENDENT of the full granite RETIRE** (reclaim ~32GB on ana-ml2 GPU1) — that stays the
  operator's call, pending brokkr R33 portfolio + production-concurrency due-diligence. Tracked: althing thread
  01KX3SGH… (worldtree-dev) + brokkr's gen-absorbs-granite consult (thread 01KX2V32…) + [[reference_litellm_gateway]].
- `[2026-07-08]` **RP-SEAT CAMPAIGN CLOSED — char-rp = Magidonia-24B-v4.3 (128K), char-rp-reasoning = Deckard-PKD
  Qwen3.5-27B (256K); both GGUF/llama.cpp on ana-ml2 GPU0 alongside gen (35B-A3B, util 0.37), ~4G GPU0 margin.**
  Arc: (1) replaced broken Angel NVFP4 with Magidonia prose + QwQ-RpR-v4 reasoning (b268f93); (2) max-context via q8_0
  KV (f570604); (3) canonical samplers for all 4 gateway seats, dvalin-derived + char-rp A/B-tuned (aac4bcf);
  (4) rebalanced gen 0.40→0.37 to fund char-rp 128K (f49c4e4); (5) RE-A/B'd the reasoning seat (operator wanted a
  DRY-tolerant model): **Deckard WON** on brokkr's frozen scorer (composite 2.176, 0/30 loops, 0/30 refusals) over
  RpR-v4 (3.716, 1/30 loop), Pantheon-Reasoning (1.383 but 7/30 refusals), Snowdrop+Gembrain (llama.cpp
  template-incompat) — deployed (5f79b40); (6) Deckard→256K (41305bf); (7) dvalin CONFIRMED Deckard samplers = the
  live A/B set is canonical (4954ca0). **GATE LESSON: a llama.cpp reasoning seat needs a STOCK template that natively

- `[2026-07-08]` **worldtree Mimir deploy-blocker resolved (mid-session):** synced `persona.envelopes.assistant` +
  `envelope_grants:[]` verbatim from the baked canonical into BOTH corviduo-dev instances (demo+personal),
  YAML-validated via each container's own parser; worldtree-dev cleared to push the Mimir-bound image. (Was my
  parked R32 1C envelope-mirror come due — see [[reference_corviduo_dev_emergency_ops]] config-sync recipe.)
- `[2026-07-08]` **OFF-THE-SHELF INFERENCE PIVOT executed — serve curated abliterated models, stop home-training.**
  Final topology: **gen = `llmfan46/Qwen3.6-35B-A3B-uncensored-heretic-NVFP4-Experts-Only`** (LIVE, modelopt, vision,
  util 0.40), **char-rp = an RP unicorn to be found on fresh context** (see Current state). Intermediate steps
  ABANDONED: Pantheon-Reasoning-27B (served briefly as gen — refuses dark fiction via DeepSeek-distilled
  refusal-reasoning, see Tried); Pantheon-27B-with-MTP for RP (bf16 MTP won't load on the compressed-tensors path);
  Angel MS3.2-24B (my NVFP4 quant = garbage). Prefer EXISTING community NVFP4/GGUF quants over self-quanting
  ("don't quant unless you have to" — operator). GGUF serving is now on the table for RP (NEVER Ollama). Gateway
  sampling-defaults wiring still PENDING.
- `[2026-07-08]` **DPO was silently running 3 epochs (harness gap) → KILLED at epoch 1.2, retargeted to 0.3
  epochs (operator call).** Root cause: `DpoConfig` had NO `epochs` field + `_dpo_config_kwargs` didn't pass
  `num_train_epochs` → DPO fell through to trl DPOConfig's default 3.0 (SFT correctly pins 1 via SftConfig.epochs
  + _sft_config_kwargs). Objective SATURATED by ~epoch 0.27 (loss~0, grad~0, acc 1.0, margins~27 flat — the
  off-policy qwopus rejected pairs are trivially separable), so epochs ~0.3→3 were pure over-optimization + a
  ~6.5h outage. No mid-run checkpoint (save_steps 500 > total steps; save only at end) → killing lost the run.
  FIX (3 edits to deployed harness, mtf-dev to canonicalize): `DpoConfig.epochs: float = 1` (mirrors SftConfig,
  float for fractions); `_dpo_config_kwargs` now passes `"num_train_epochs": cfg.epochs`; recipe `dpo.epochs: 0.3`.
  GPU-free verified (dpo.epochs=0.3 → num_train_epochs=0.3). Relaunched at 0.3 epoch (~30min precompute + ~12min
  train = ~45min). **DONE + SANITY-CHECKED (exit 0, ~70min wall: ~30min fixed precompute + 45 steps @ ~51s/step;
  train_loss 1.4e-5 @ epoch 0.301).** Fresh `data/spike/dpo_adapter/adapter_model.safetensors` (123MB) + checkpoint-45
  banked. **3-way greedy sanity (base vs SFT vs DPO, via peft load + disable_adapter/set_adapter on GPU0):
  ALL THREE DISTINCT** (base≠sft≠dpo) → full SFT→DPO pipeline applies end-to-end at inference. **DPO 0.3ep is
  COHERENT, fluent, NOT degenerate** (early-stop avoided over-optimization) but the quality delta on a neutral
  literary prompt is SUBTLE (DPO shares SFT's structure — it continues from it — with minor stylistic drift,
  arguably slightly MORE genre-clichéd). Verdict: mechanics proven, quality gain modest as predicted for 0.3ep
  on off-policy pairs; the real unlock remains on-policy rejected regen + on-domain (explicit E-RP) eval +
  the LitBench/holdout run. gen+rp RESTORED healthy. Next: serve fork (SGLang-finish vs merge) on the DPO
  adapter — same rekey_lora_for_vllm.py (zero-z) applies unchanged (mtf-dev confirmed).
- `[2026-07-08]` **T1 DPO leg is RUNNING (unblocked) — 2 fixes applied to deployed backend.py.**
  Blocker resolved: (1) **mtf-dev's v0.0.42 stub** `_stub_missing_optional_integrations` (last-resort sys.meta_path
  finder → missing mergekit/llm_blender/weave resolve to MagicMock, never called → zero numerics risk; applied
  VERBATIM to deployed `src/model_training_forge/train/backend.py` after `_unsloth_available()` + call-site before
  `from trl import DPOTrainer`); (2) **my cosmetic `warnings_issued` shim** (trl-0.24 DPOTrainer.__init__:405 does
  `model.warnings_issued["estimate_tokens"]=True` for warning-suppression; custom Qwen3_5 class under transformers
  5.5.0 lacks the attr → `if not hasattr(model,"warnings_issued"): model.warnings_issued={}` before the
  DPOTrainer(...).train() at backend.py:305 — cosmetic, zero training impact). Both edits are on the DEPLOYED
  un-git'd copy only → **mtf-dev must canonicalize the warnings_issued shim into their repo** (told them). DPO
  confirmed training: model loaded (851 shards), full 1196 pairs processed, in precompute_ref_log_probs (GPU0 93%
  util, 54.8GB). Completion watcher armed (bg task) → restore gen+rp + verify dpo_adapter + ping mtf-dev on exit.
  gen+rp STOPPED for the run (authorized window). Output → data/spike/dpo_adapter.
- `[2026-07-08]` **T1 DPO leg launch — prior BLOCK (now resolved above), kept for the launch recipe.**
  Operator authorized the full DPO stage (via mtf-dev) + went AFK 2h. **PROVEN LAUNCH RECIPE** (replicates the
  SFT container `aeon-t1-sft` exactly, only `--stage sft`→`dpo`): `sudo docker run -d --name aeon-t1-dpo
  --entrypoint python3 --gpus all -e CUDA_VISIBLE_DEVICES=0 -e MTF_FORCE_TRL=1 -e PYTHONPATH=/mtf/src
  -e PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True -v /home/lkraven/model-training-forge:/mtf -v /tank:/tank
  -w /mtf aeon-trainer:latest -u scripts/train.py --recipe recipes/training/qwen-3.5-122b-erp-lora/train.aeon-27b.yaml
  --stage dpo`. **CRITICAL: `--entrypoint python3` is REQUIRED** — aeon-trainer's default entrypoint is
  `["vllm","serve"]` (FROM vllm/vllm-openai) → without the override it runs vllm + hits a torch-ABI crash.
  Dataset verified (pairs_dataset=train.flat.json=1196 pairs). **THE BLOCK:** `from trl import DPOTrainer`
  (backend.py:256) eagerly pulls TRL 0.24.0's WHOLE optional-integration set — cascade: mergekit(missing)→
  immutables→**mergekit-0.1.4↔pydantic-2.13 HARD incompat** (needs pydantic==2.10.6)→llm_blender→dataclasses_json→
  **llm_blender-0.0.2↔transformers-5.5.0 HARD incompat** (TRANSFORMERS_CACHE removed, needs source patch)→weave→
  (more). NONE used by our pair-based DPO. `pip install mergekit` w/deps is UNSAFE (downgrades accelerate
  1.14→1.6). Safe partial recipe derived (core libs held: torch2.10/tf5.5.0/trl0.24.0/peft0.19.1/accel1.14.0)
  but non-convergent → TRULY BLOCKING per operator's carve-out. Did NOT force-hack the proven training image.
  Handed full diagnosis + recommended fix (lazy-import TRL patch, opt b) to mtf-dev (thread 01KWZG8GJX,
  expects-reply, monitor armed). gen+rp RESTORED healthy. Relaunch = 1 min once mtf-dev delivers a working image.
- `[2026-07-07]` **SGLang zc hot-swap: 2-line patch RAN → PARTIAL. Cleared startup + self-attn E2E, GDN
  in_proj hit 2 MORE name-routing gaps → MERGE recommended.** Root cause was a NAME-routing gap (not the
  feared shape-assert): `lora/utils.py:235` hardcoded `params_mapping` lacked `in_proj_qkv/in_proj_z →
  in_proj_qkvz`. Patched those 2 lines (overlay bind-mount) → `init_lora_shapes` passed, server up, self-attn
  loaded end-to-end. But the SAME missing GDN mapping bit 2 MORE resolvers: adapter-load skipped 192 in_proj
  weights, and inference `utils.py:300 get_target_module_name` (substring match) RAISED → 500 + scheduler
  died. So GDN LoRA name-routing is incomplete in ≥3 SGLang paths (fixed 1). NOT shape-intractable (self-attn
  proves the separate-key→fused-buffer machinery works), but NOT "one targeted fix" either → per operator's
  LAST-shot rule → MERGE. mtf-dev looped + closed (thread 01KWZDZFYN…); B/A shard-math never reached.
  Supersedes the "SGLang wants a THIRD format" framing — no new adapter format needed.
- `[2026-07-07]` **T1 (retargeted qwopus-122B→AEON-27B) SFT COMPLETE on ana-ml2** — all-TRL torch-GDN,
  batch1/accum8/GC-off, 1 epoch ~9h @ 0.25 s/s, loss 2.445, adapter banked. Supersedes the 2026-07-05
  cloud-vs-smoke venue decision: AEON-27B's 52G bf16 fits one Blackwell → ran on-prem in ~9h (no cloud,
  no full-fleet outage). GC is NOT the throughput lever (batch1-no-GC == batch4+GC at 0.25; dvalin's 0.565
  was warmup-noise from a 30-sample smoke); ~0.25 s/s is the torch-GDN floor (only FLA beats it, sm_120-
  blocked #913). `reference_t1_cloud_train_plan`.
- `[2026-07-07]` **T1 hot-swap on vLLM NVFP4 is DEAD — vLLM 0.24.0 qwen3_5 LoRA-application silent no-op**
  (#47639 open / fix PR #47640 open / regression from #37912). Proven quant-agnostic (NVFP4+FP8) AND
  adapter-format-agnostic (separate `zc` loads-but-inert; fused rejected); #47640 guard-patch overlay didn't
  fix. Root-caused by a 3-peer dwarf panel (eitri/regin/dvalin); their vLLM issue refs verified real via
  GitHub API. Engine mirror-image: vLLM wants SEPARATE keys, SGLang wants FUSED.
- `[2026-07-07]` **HARD REQUIREMENT restated: hot-swappable LoRA or ABANDON.** Merge is NOT a solution for
  this requirement (static; reserved for a later RP-quant track). SGLang is the last hot-swap shot; if it
  can't apply, park the adapter + file upstream repros. `reference_lora_training_worker` (adjacent).
- `[2026-07-07]` **comfy-dev in-arbo LoRA-training worker DONE** — built/deployed/validated Phases 1+2

  impl deferred. `services/lora-training-worker/`, commits 888ba6a→b617a8b. `reference_lora_training_worker`.
- `[2026-07-06]` **infra-ops NOPASSWD sudo confirmed on irv-ml1 + ana-ml2** (the arbo memory's "NOT
  infra-ops on irv-ml1" was stale) — enabled the worker deploy + every ana-ml2 hot-swap smoke.
- `[2026-07-05]` **T1 training venue: CLOUD recommended; operator chose smoke-first on ana-ml2.**
  On-prem ruled out (ana-ml2 full — both 96G GPUs ~93G used): keep-serving = NVMe offload ~6-8 DAYS;
  full ana-ml2 shutdown = CPU offload ~1 DAY but a whole-fleet outage. Cloud Vast.ai 8×80GB (no
  offload → ~3-6h, ~$60-500, zero fleet impact) is the clean alt (mtf-dev + infra-ops both rec;
  Vast for its no-content-AUP marketplace + likely-existing VastBlue account). Operator's next step
  = the ana-ml2 CPU-offload SMOKE (~60 steps) to get real samples/sec before the full-outage-vs-cloud
  call. HF base verified public (zero-auth pull). Runbook + gotchas in `reference_t1_cloud_train_plan`.

- `[2026-07-05]` **glm-5.2 canonical limits recorded** (probed live vs z.ai): **1,048,576 (1M) input
  context / 131,072 (128K) max output**; NO gateway-side cap (pure passthrough → z.ai's limits are
  effective). Written to the config comment (commit `624a07e`) + `reference_litellm_gateway`.

- `[2026-07-04]` **character-rp: gateway-forwarding proven + role pre-staged + #344 shipped.**
  Empirically confirmed per-request `extra_body` (top_k/repetition_penalty) forwards through the
  `gen-reasoning` LiteLLM alias to vLLM + standard params override the alias defaults — no gateway
  cap needed (I over-built a dedicated alias, operator corrected, reverted with zero fleet impact).
  Pre-staged the `character-rp` role into demo+personal bind-mount `model_roles.yaml` (byte-verified
  on b18; caught the cached-registry ordering). worldtree-dev shipped **#344 (v1.0.0b19)** for the
  durable-agent override-drop. spend_logs spot-check queued (ratatoskr's timestamp ping).

- `[2026-07-04]` **althing v2 herald+receiver formalized as systemd on nh3-dev.** `althing-herald.service`
  (Restart=always, **Environment=PATH incl ~/.cargo/bin** — the pane-dispatch fix) + `althing-receiver.service`
  (v2 → pillar-3 `/owner/*` live); stale forseti unit removed; both on v2.0.0b2, canonicalized by
  forseti. `reference_nh3_dev_althing_herald`.

- `[2026-07-04]` **LitBench-RM respun (irv-ml1 A6000, comfyui displaced)** for T1's reward ensemble;
  operator sole comfyui consumer, holding image-gen until LitBench done. `reference_litbench_rm_irv_ml1`.

- `[2026-07-03]` **ratatoskr-dev DEMO Heimdall key provisioned (R30 φ0).** Minted a tier-user key on
  the demo via `POST /admin/keys` (bootstrap admin key), mirroring their personal base consumer (no
  character-binding); base-agent affect reads work ungated. `reference_worldtree_demo_key_mint`.

- `[2026-07-02]` **mtf-dev granite harness-spike ran GREEN — MECHANICAL only, efficacy DEFERRED to
  the T1 run.** Trainer TRL SFT→DPO→eval seam proven end-to-end on a synthetic fixture (not the E-RP
  corpus); operator DECIDED no intermediate real-efficacy granite spike (uninterpretable proxy —
  arch gap + abliteration axis). `reference_gen_qwopus_122b`.

- `[2026-07-01]` **Worldtree #332 embed-recall diagnosed + scoped-log view/tunnel provisioned + fix

- `[2026-07-01]` **qwopus native MTP speculative-decode tested on `gen` → NOT kept** (+12% single-stream,
  −15–20% aggregate at concurrency, silently drops min_p/logit_bias). Banked for T1. `reference_gen_qwopus_122b`.

- `[2026-07-01]` **Deckard trial → reverted to qwopus (`gen`)** (won writing "in every way" but ~36 vs

## Tried and abandoned

- `[2026-07-09]` **FP8 breaks mOrpheus audio-token generation.** `--quantization fp8` on the 3B → 0 valid SNAC
  frames even at GREEDY (degenerate audio+text mix, no start-of-speech); bf16 is clean (28/28 frames). Quant-breaks-
  TTS, same class as the Angel-NVFP4 lesson below. bf16 is REQUIRED (so the operator's "util 0.1" wish is moot — the
  bf16 weights alone are 6.6GB). NB the raw-token benchmark RTF 0.50 was fp8+graphs = never real.
- `[2026-07-09]` **`vllm/vllm-openai:latest` crashes on Ampere IMPORT** — Blackwell-only kernels (oink/aiter,
  `has_device_capability(100)`) die during import on the 3090/A6000. Pin **v0.23.0** on irv-ml1's Ampere GPUs.
  (`vllm/vllm-omni:v0.18.0` has a different entrypoint — don't use it either.)
- `[2026-07-09]` **Per-frame CPU SNAC decode is too slow for streaming** — per-call overhead × ~60 frames serialized
  → RTF 2.2 (WORSE than whole-clip's 1.0). Fix = **windowed chunk decode** (every 6 frames decode a [2 ctx | 6 | 2 ctx]
  window, emit the middle 6 → seamless, O(1)/frame, RTF ~0.97, TTFA ~0.8s).
- `[2026-07-09]` **Sentence-chunking TTS loses prosody** — generating each sentence cold flattens the intonation that
  spans a line. Chunk by QUOTED SECTION (whole quote = one gen call). Also: `repetition_penalty` >1.1 BREAKS cloning
  (penalizes the ~1100 in-context reference audio tokens; keep ≤1.1 on the clone path).
- `[2026-07-09]` **HF whisper datasets aren't actually whispered.** Claris-Whispered-English measures voiced 0.8
  (not a whisper) + IPA transcripts; `datasets` audio decode needs torchcodec (wants CUDA-13, incompatible w/ the
  cu124 venv). LPC DSP-whisperize went unstable (NaN). **kokoro `af_nicole` IS a genuine whisper** (voiced 0.24) —
  that (operator's pointer) is the working whisper reference source, not TTS-voice screening or dataset-hunting.
- `[2026-07-08]` **Angel (allura-org/MS3.2-24b-Angel) self-quanted to NVFP4 = GARBAGE.** llm-compressor W4A4 NVFP4
  (compressed-tensors, MLP-quantized, attn/vision bf16) of the Mistral3 dense 24B produces gibberish EVEN AT GREEDY
  (temp 0) → the quant itself is broken, not the tokenizer or sampler. Same recipe worked on the qwen models.
  Mistral3 + W4A4 NVFP4 via llm-compressor is bad. → for the RP seat, going **GGUF (llama.cpp)** to sidestep the
  whole NVFP4-quant surface.
- `[2026-07-08]` **Mistral3 + vLLM tokenizer/vision traps (serve `MS3.2-24b`, vLLM 0.24).** (a) HF `tokenizer.json`
  for Mistral = **GARBAGE output** — the card's "use the official Mistral tokenizer" warning is REAL; must use the
  `tekken.json`/mistral tokenizer. (b) BUT `--tokenizer-mode mistral` + vision **CRASHES** (`Failed to apply
  PixtralProcessor on {'text': '[IMG]'}`; and with tekken.json present in auto mode, `CachedMistralCommonBackend has
  no attribute is_fast`). So it's **mistral-tokenizer OR vision, not both** on this vLLM. Text-only + mistral
  tokenizer serves clean (`--limit-mm-per-prompt '{"image": 0}'`). **GGUF/llama.cpp avoids all of this** (native
  mistral tokenizer + vision).
- `[2026-07-08]` **Pantheon-Reasoning-27B refuses dark fiction DESPITE an abliterated base.** The base
  (`llmfan46 heretic`) writes freely (thinking-off), but Gryphe distilled the reasoning traces from **DeepSeek 3.2**
  (safety-aligned) onto every turn (`preserve_thinking:true`) → the model reasons ITSELF into refusals in the
  `<think>` phase (collapses to empty output). Fix: thinking-off OR an uncensor system prompt (both verified).
  **Lesson: a reasoning finetune of an abliterated base can re-censor via its reasoning-trace TEACHER; the raw
  abliterated base is cleaner** — this is WHY the pivot went to the llmfan46 heretic base for gen.
- `[2026-07-08]` **Pantheon-27B MTP on vLLM compressed-tensors = 0% acceptance.** MTP is a separate **bf16** head
  (`mtp.*`, in `model-auxiliary.safetensors`, 15 tensors); AEON preserved it by INJECTING the bf16 head into the
  quant output (NOT re-quantizing — confirmed AEON's nvfp4 mtp is bf16). Built pantheon-27b-mtp = compressed-tensors
  main + injected bf16 mtp + `text_config.mtp_num_hidden_layers=1` → vLLM detected the MTP but SKIPPED the bf16
  self_attn weights → 0/192 draft tokens accepted. **The bf16 MTP head only loads on the MODELOPT main-model format
  (like AEON), not compressed-tensors.** (Moot — operator dropped MTP for gen; not needed for the non-reasoning RP.)
- `[2026-07-07]` **vLLM 0.24.0 qwen3_5 LoRA application = silent no-op (#47639).** Adapter loads HTTP 200
  but zero deltas at inference. NOT quant (NVFP4 AND FP8 both inert). NOT adapter format (separate `zc`
  adapter — correct per vLLM's `check_unexpected_modules` allowlist — loads clean but inert; the fused-key
  rekey is rejected). The #47640 None-group guard-patch overlay did NOT fix it (failure is UPSTREAM of
  `expand_packed_lora` — the separate→fused mapping never happens). Fix PR #47640 is OPEN (unmerged) so no
  version-bump helps. Merge bakes deltas in (bypasses this) but is static.
- `[2026-07-07]` **SGLang generic image can't LOAD our NVFP4 AEON** — ModelOptModelLoader weight-shape/
  packing mismatch ([1024,5120] vs [1024,2560], 2-fp4/byte). NVFP4-on-SGLang needs the dedicated
  `qwen36-27b-nvfp4` dev image or a requant to SGLang's format. bf16 loads fine (arch supported; crash was
  quant-loader-specific).
- `[2026-07-07]` **SGLang `--lora-target-modules` CLI enum REJECTS the GDN names its own resolver asks for**
  (invalid choice: 'in_proj_qkv'); `'all'` resolves to the FUSED set (qkv_proj/in_proj_qkvz). SGLang wants
  its OWN packed layout (base r16 + `get_stacked_multiply=3`, NOT a pre-fused rank-48 qkv → the [48]-vs-[144]
  shape assert). A THIRD adapter format; version-exact source needed (`:latest`=0.5.13, NOT `main`).
- `[2026-07-07]` **Engine invocation footguns cost several wasted serve-bounces this session** — `docker run
  --rm` ate crash logs; duplicated `serve` (vLLM image entrypoint is already `["vllm","serve"]`);
  `--max-lora-rank 48` invalid (choices 1/8/16/32/64… → use 64); parens in `echo` inside `ssh host -c "…"`
  break the remote shell. LESSON: verify engine launch flags (`--help`, GPU-free) + never `--rm` a container
  whose crash logs you need, BEFORE bouncing a production serve.
- `[2026-07-04]` **LiteLLM (this gateway version) mutates the SHARED deployment config in-place on
  per-request sampler-param merge** → my deliberately-invalid `top_k=-5` forwarding-probe bled into a
  param-less character-rp request (vLLM 400, ONE-OFF, self-cleared by a later valid probe). NOT
  caching (none configured), NOT a config change. **Never fire invalid/distinctive sampler values at
  a SHARED gateway alias with live consumers** — use a throwaway alias, or a `docker restart litellm`
  flushes residual carryover. `feedback_litellm_shared_param_mutation`.

- `[2026-07-04]` **A systemd `--user` daemon that shells out to `~/.cargo/bin`/`~/.local/bin` tools
  needs an explicit `Environment=PATH`** — the minimal `--user` default silently drops them. The
  althing herald lost `zellij` → silent `pane-miss` for ALL config-backed TUI/pane agents; CC + FIFO
  routes were unaffected, so it was invisible from a CC session. `reference_nh3_dev_althing_herald`.

- `[2026-07-04]` **On-prem T1 train that keeps ANY ana-ml2 serving up = ~6-8 DAYS** (1-GPU + NVMe
  ZeRO-Infinity offload; MoE ~10B-active cuts FLOPs but NOT the 244G base's param I/O). The only fast
  on-prem path is a FULL ana-ml2 shutdown (both GPUs + the ~421G vLLM RAM freed → base fits in the
  566G CPU RAM) → CPU offload → ~1-day full-fleet outage. Cloud (no offload) = hours. `reference_t1_cloud_train_plan`.

- `[2026-07-01]` **A personal-Worldtree CI deploy that fails ~85s in with "not found / unauthorized"
  is usually the pull-only-vs-build RACE, not registry-auth.** `deploy-personal.yml` is PULL-ONLY but
  fires on the `staging/vX` tag simultaneously with `deploy.yml`'s build → pulls before the push
  finishes. FIX: re-run once built, or gate on `workflow_run: completed`.

- `[2026-07-01]` **MTP/spec-decode on a SHARED serving model helps single-stream but HURTS
  moderate-concurrency aggregate + silently ignores `min_p`/`logit_bias`** (qwopus `gen`: N=1 +12%,
  N=4 −20%). Reserve for dedicated/interactive deployments.

- `[2026-07-02]` **irv-ml1 `/worktank` ROOT is root-owned — lkraven can't write there (irv-ml1 sudo
  needs a password) → stage model pulls to `/home`.** PIN THE A6000 BY UUID for training (native-CUDA
  ordering differs vs docker; the 3090 index 0 is usually near-full → OOM). `CUDA_VISIBLE_DEVICES=GPU-<uuid>`.
