# Persistent memory — eshpfi-management _Last updated: 2026-08-26_ > **Always check for `/tmp/infra-ops-handoff.md`** — if it exists and its > `Written:` stamp is under an hour old, read it (it carries the in-flight > handoff from the previous session), then delete it. Older than an hour: > stale — delete it unread. ## 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//`; 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.

Manual redeploy `sudo -u deploy bash -c 'cd /opt/soong-lab && docker compose pull && docker compose up -d'`. → `archival-memory.md` (archived 2026-08-16) | | `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-.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:` + `: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 :/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 2026-08-26 ~09:45 PDT — **run 2 is done, gated (FAIL), and serving. Run 3's corpus is BUILT and HELD: brokkr is redoing the recipe after a corpus-containment defect we found together.** Nothing is training._ - **🔴 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). ## Recent decisions - `[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. - `[2026-08-26]` **Run 2's gate FAILED and is recorded as a FAIL** — T3 constraint −12.0 against a ~1 pt floor. 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; the pair prices what the abliteration cost. Plus the long-form-only stability regression a short-answer gate would have passed, and PIPPA's 123-word clip in the length signal. → `persistent-memory.d/2026-08-26-erp-run2-complete-and-served.md` - `[2026-08-26]` **Run 2 complete, merged, coherence-gated and serving as `erp-tune-v2`** — stock-instruct base, and the mask proven by a −221,712 loss-token delta against byte-identical context. Also the p50 claim I asserted and had to withdraw. → `persistent-memory.d/2026-08-26-erp-run2-complete-and-served.md` - `[2026-08-26]` **Playbook §4 written: "when the artifact lies about itself"** — seven landmines plus a pre-launch checklist, from a night in which *three separate fixes each shipped a check that could not fail*. The unifying line is brokkr's: when you change what an artifact means, every derived artifact keyed on the old meaning is now a liar. Commits `dae6ede` → `d54f256`; the doc is `docs/pfi/training-throughput-playbook.md` (filename kept for inbound links; scope is now wider than the name). - `[2026-08-26]` **Served under a NEW name on a NEW port (`erp-tune-v2` / :8098), never re-pointing `erp-tune-v1`.** Run 1's artifact still exists and is still what that name refers to; re-pointing would be the silent substitution the standing no-false-aliases rule forbids. brokkr independently asked for the same and additionally wants the concrete backing model + date in provenance, not just the alias — an alias has silently changed meaning under recorded results before. - `[2026-08-26]` **DPO stage gated on an axis-list decision that is not mine to make** — `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. ⚠ Do not install `trl` (or anything) into the training venv **while a run is saving** — a resolution that upgrades transformers under a live process can break its save path. - `[2026-08-25]` **The ERP/RP tune COMPLETED in 7.36h and passed its gate on the axis it was built for** — diversity 22x its noise floor, attractor −11.3pt, zero memorisation on both arms. Also the noise-floor near-miss: brokkr was one step from reporting a 13-point T6 regression sitting inside twice his instrument's own variance. → `persistent-memory.d/2026-08-25-erp-tune-run2-complete.md` - `[2026-08-25]` **8.6% MFU was an accounting artifact — real utilisation 17-20%, and the cost was attention on AMPERE kernels.** Two independent methods agreed to 2.6 points. Fixed by bucketing (padding 29.9%→0.0%) plus flex_attention. ⚠ Carries the dynamo recompile-ceiling trap that produced two wrong published conclusions. → `persistent-memory.d/2026-08-25-mfu-root-caused-attention.md` - `[2026-08-25]` **NVFP4A16 serving pipeline built and validated; MERGED WEIGHTS ARE MANDATORY.** vLLM cannot serve a LoRA on ANY Gemma-4 — `get_expert_mapping` is unimplemented and the check branches on MoE-ness, not quantization. Plus the landmine: a `targets=["Linear"]` recipe misses all 11,520 expert tensors silently. → `persistent-memory.d/2026-08-25-nvfp4-serving-pipeline.md` - `[2026-08-25]` **Refusal retention measured (base 0/100 → tuned 29/100, 71 still complying) — but on the WRONG AXIS.** `harmful_behaviors` is general harm; the abliteration was run for explicit fiction. The convenient set with a recorded baseline was not the right one. → `persistent-memory.d/2026-08-25-refusal-retention-probe.md` - `[2026-08-25]` **Worldtree b188 + b189 shipped; bridge extracted to `pfi/wt-matrix-bridge` because `vh` is a USER not an ORG** and no service account can ever publish to a user namespace. Plus the selene catalog entry that lied about what answers, and a #411 diagnosis I got wrong twice before a directory probe settled it. → `persistent-memory.d/2026-08-25-worldtree-b188-b189-and-selene.md` - `[2026-08-25]` **Run 2's base is an OPEN OPERATOR DECISION, deliberately not staged** — four options with materially different safety postures, detailed in Current state. Tracked at althing thread `01M0WQ8W5574KMEVCHCEKEXNS5`. ⚠ Do not let it get filed as a config knob; it is a reversal of the trainee-selection decision. - `[2026-08-25]` **Fused MoE kernel path — DEFERRED, tracked at park `fused-moe-kernel-path-for-gemma-4-moe-training` (id 47).** Operator: "note the fused MoE kernel for round two… if we nail it soon, the math has us wanting to restart the run anyway." Training MFU is **8.6%** (27.1 of a benchmarked 313.8 TFLOPS) because `transformers` runs the Gemma-4 experts in a Python loop — 128 experts × 30 layers, ~11,500 iterations per step under gradient checkpointing. ⚠ **The same fused 3-D expert layout that made bitsandbytes skip 88.5% of the model is exactly what a grouped GEMM wants** — the format is good for storage and for fused kernels, and hostile only to naive iteration. Two fixes: `group_by_length` (−29.9% compute, free, but breaks the seeded order manifest and re-opens a batch-composition call brokkr already made) and a grouped-GEMM/compiled MoE forward (the remaining ~10×). **Not applied to the live run** — restarting mid-flight to change batch ordering was judged a bad trade at step ~50 of 1,312. - `[2026-08-25]` **The ERP/RP tune LAUNCHED after 12 harness defects and an operator override of the corpus gate.** Four of the twelve would have crashed the run; two were INERT GATES that passed because they could not fail. Run is `/tank/erp-tune/run-01`, harness eitri-smithy `997c4a4`. Full arc — override, defects, sizing, the measured MFU — in the in-flight section and `docs/pfi/gemma4-erp-tune-sizing.md`. - `[2026-08-24]` **char-rp seat swapped to the Gemma-4 26B-A4B MoE; abliterated trainee base staged and measured.** OOM root-caused to `--gpu-memory-utilization` not covering CUDA context (and to gen's footprint GROWING WITH UPTIME); a benchmark finding retracted because it scored below chance; abliteration isolated at −0.6 core points but it MOVES capability rather than removing it. → `persistent-memory.d/2026-08-24-charrp-gemma4-moe-swap-and-trainee.md` - `[2026-08-24]` **Serving the tuned ERP model: LoRA-on-NVFP4 PREFERRED, merged weights the expected fallback — and the recorded objection may be STALE.** Operator: "if you CAN load it as a lora, all the better, the issue is that we will want to run nvfp4 weights, which we had some serious trouble with loading loras on top of nvfp4." ⚠ **The archived root-cause says it was NOT NVFP4-specific**: `[2026-07-07]` vLLM 0.24.0 qwen3_5 LoRA application was a silent no-op (#47639, regression from #37912) — adapter loads HTTP 200, zero deltas at inference, proven **quant-agnostic (NVFP4 AND FP8 both inert)** and adapter-format-agnostic by a 3-peer dwarf panel. Fix PR #47640 was OPEN then. **ana-ml2 is FAR past 0.24.0 and the box runs a SPREAD, not one version** (measured 2026-08-24): `gen` on `nightly-311b3513` = **0.27.2rc1.dev150**, `mog-sec` on `nightly-e9d1398d` = 0.26.1rc1.dev1102, the small seats still on 0.24.0, and char-rp/trainee-bench pinned to v0.26.0. ⚠ **`vllm/vllm-openai:v0.27.1` is already ON DISK, unused** — a TAGGED release, which is the right retest target: no nightly variance, no pull, ~4 months past the diagnosis. So: RETEST hot-swap LoRA on **v0.27.1** before designing around merge — it is cheap, and if it works the post-tune gate can be two aliases on one engine. If it still no-ops, merged weights it is, which means the harness must EMIT merged weights and Eitri needs that in the contract while he is early. Tracked at this snapshot commit; settle it in the QLoRA sizing conversation. - `[2026-08-24]` **Homepage rebuilt on Australis Skyfall; light mode shipped.** Two findings worth more than the theme: **(a)** the Skyfall bundle including its canonical light ramp was sitting in this repo's git history at `45c1995` — check `git show` before concluding a vendored design asset is lost; **(b)** removing `theme:` from `settings.yaml` deterministically breaks the dashboard render (six recreates empty, restoring the key fixed it in 12s), which is the first confirmed cause of the "tab bar goes missing" symptom. Retires the `homepage.log` size lead from earlier the same day — it did nothing on this episode. → `persistent-memory.d/2026-08-24-homepage-uniform-grid.md` - `[2026-08-24]` **Homepage reorganised on the axis "do I open this?" — UI groups expanded on top, API/agent groups collapsed at the bottom** (operator-delegated: "re-categorize however you want"). Load-bearing constraint: `homepage.group` is read at container CREATION, so the 16 GPU-backed model seats keep their unlovely names rather than eat a recreate — `initiallyCollapsed` + order is free.

Repo creation needs `write:user` + `write:repository` + `write:organization`; `POST /users/{u}/tokens` is basic-auth only, so minting needs the account password. Default new repos to `pfi/`. (`vh/eitri-smithy` was its first tenant, then moved.) - `[2026-08-23]` **Booth: kept boards are deletable and link rows are prunable.** `release` on a kept card drops the sentinel so the existing × applies; `booth links` / `booth unlink ` prune one row. Rows are addressed by **content id, never position** — the board is append-only and multi-writer. **Releasing a board RESETS its TTL clock** (unlink bumps the dir mtime), so unkeep-and-wait is a 24h delay, not a delete.

Also measured: the KV pool varies ~6.6% between boots, so max-model-len must be sized against the *lower* observation. (`6e82899`) - `[2026-08-22]` **Max-Q 1.8× spread does NOT apply to LLM decode — measured, not argued.** ana-ml2 draws 256–266 W of 300 W under sustained 100% decode with `SW Power Cap: Not Active` and clocks pinned. Corrected to brokkr-smithy-dev after I had lent the claim credibility; 122B figure (~90–93 tok/s at 262K) stands as a straight number. - `[2026-08-21]` **ESH internal IPv6 live on two LANs; the Cityside v4 static is a CARRIER problem, proven.** A full gateway reboot forced a fresh DHCP DISCOVER and returned the identical CGNAT address.

Recipe maps 1:1 (131 tensors); capture succeeded only in **fp32** — transformers' Qwen3.5 DeltaNet linear-attn NaNs nondeterministically in bf16 without the unbuildable `causal-conv1d` kernel (precision cancellation, not overflow).

Moved to the PCH `iTCO_wdt` under systemd. Also: a single cross-VLAN DNS entry with no secondary turns any VM outage into a whole-site outage. → `persistent-memory.d/2026-08-19-esh-pve-freeze-dns-spof.md` - `[2026-08-19]` **Fleet `.internal` DNS built and live — git-sourced, agent-managed, three resolvers.** Zone-scoped authority (ESH's hand-made `esteban.net` rewrites survive); the colo had no resolver at all; v6 column empty on purpose because SLAAC addresses rotate. → `persistent-memory.d/2026-08-19-fleet-internal-dns.md` - `[2026-08-19]` **waterland studio containerised on irv-ml1 — three landmines, all measured.** cupy needs CUDA *headers* the host had by accident; `uv run` re-syncs and prunes cupy at RUNTIME; the A6000 is container-index 0, not the host's 1. → `persistent-memory.d/2026-08-19-waterland-studio-containerised.md` - `[2026-08-19]` **Homepage cleaned up, then themed with Australis Skyfall + an Arbo-generated background.** Includes the hour lost to a self-healing tab-bar red herring, and the CSS-iteration loop that prevents it recurring. → `persistent-memory.d/2026-08-19-homepage-skyfall-theme.md` - `[2026-08-19]` **Four unmanaged stacks found on live hosts — two quietly broken.** A dashboard card is a cheap census of what is actually running; check whether the stack is even in `stacks/` before debugging the symptom. → `persistent-memory.d/2026-08-19-unmanaged-stacks-searxng-seafile.md` - `[2026-08-19]` **`claude-bot` granted read on `vh/waterland`** (operator-empowered, verified `admin:false push:false pull:true`) so irv-ml1 can self-update without the operator's site-admin token living on a GPU box. Precedent for the standing migrate-off-operator-creds directive: grant the service account, wire a repo-scoped 0600 credential helper, keep the remote URL clean. Commit `8189076`. - `[2026-08-19]` **AI-tab Dormant regrouping BELAYED by the operator** — six seats (char-rp Magidonia, char-rp-reasoning Heretic2, Granite summarizer, Qwen-Image-Bench, Skaldsong, Chatterbox Fast) show amber EXITED inside live groups rather than `AI - Dormant`. Fix is a label change + recreate per stack; needs the operator's read on which are retired vs temporarily down. `untracked by operator choice` (his words: "belay the ai dormant regrouping for now"). - `[2026-08-18]` **esh-pve-nas migration STAGED — and staging is where three landmines surfaced, none of which the plan predicted.** (1) The runbook's `/boot` LV had **nowhere to live**: VG `pve` had 4 MB free and mounted ext4 cannot shrink, so the space came from the 768 MB swap LV (operator's call: shrink to 256 MB, not drop). (2) The runbook's `zpool set cachefile=… nvme` would have **broken the NAS** — populating a cache flips the host to import-by-cache, and a one-pool cache leaves `ssd`+`tank` unimported under CT 103's twelve bind mounts. (3) **`update-grub` silently emitted a pool-less `root=ZFS=/ROOT/pve-1`**, because GRUB's ZFS reader cannot open a pool with `encryption`/`large_dnode`/`zstd_compress` and the probe failure is swallowed. All three were caught by *verify steps that asserted effective state*, not by reading the plan. → `persistent-memory.d/2026-08-17-esh-pve-nas-dom.md` - `[2026-08-17]` **esh-pve-nas PVE root is on a USB DOM — mitigated, and the migration replanned to split boot from root.** Operator's design beats my reinstall plan; wear was never the issue, blocked patching is. → `persistent-memory.d/2026-08-17-esh-pve-nas-dom.md` - `[2026-08-17]` **irv-ml1 cleared of 782 GB, and Homepage brought under version control.** One dead-looking Gradio app pinned three delete targets at once; `/opt/ComfyUI` is NOT the ComfyUI that serves. → `persistent-memory.d/2026-08-17-irv-ml1-cleanup-homepage.md` - `[2026-08-17]` **Gen seat swapped to `absolute-heresy` — and the three bugs the swap exposed are worth more than the swap.** Candidate `MuXodious/Qwen3.8-27B-absolute-heresy` (Heretic v1.4.0 + SOMPOA, T377) beat the incumbent on refusals AND KL simultaneously, which is the unusual part — those normally trade off. Validated on the probe port per operator ruling, promoted, all 7 aliases green. **Durable lessons banked:** (1) **A CPU-only MTP head hash can replace the ~56 GB bf16 acceptance gate.** The `Qwen3_5ForConditionalGeneration` wrapper never loads the MTP head, so PEFT merges / Heretic runs / llm-compressor passes all leave `mtp.*` pristine — hashing it against a head we have already measured (the incumbent's, 47.7%) answers the question for free. Predicted 47.7%, measured 47.2%. Saved downing meromero. Tool: `services/gen-seat-mixed-quant/compare_mtp_head.py` (hash bf16 via **uint8 reinterpret** — numpy has no bfloat16). (2) **`post_quant.py` assumed a standalone `model-mtp.safetensors`**; a full checkpoint keeps `mtp.*` in a NUMBERED shard, so the copy silently no-op'd while the index was still rewritten to point at a file that never existed — 15 unresolvable tensors behind a correct-looking tensor count. Its own FAILED-CHECKS assertion caught it; **that is why the check exists rather than an assumption**. Fixed to extract. (3) **A probe that does not mirror the live seat manufactures failures.** `serve_probe.sh` hardcoded `:latest` (seat is a pinned nightly for #51113), had no tool-call/reasoning parsers, and its `--speculative-config` JSON died twice on quoting — **bash BRACE-EXPANDS `{"a":1,"b":2}` on the comma** unless single-quoted at the REMOTE shell. Adding the seat's flags took the surface test from 5/6 to **6/6**; the "tool calling broken" result was pure probe config.

Topology as VERIFIED (a prior turn assumed wrong and was corrected): UniFi↔UniFi = **Site Magic**; colo↔UniFi = **IPsec IKEv2** (`pfi-ana-nh3` 158M/165M pkt = the workhorse, `ana-to-eshudm`); **WireGuard is an RA convention only, host-based on `ana-wg`** UDP 31337 behind a FortiGate VIP — the FortiGate never terminates WG (FortiOS 7.2 has none; 7.4 added it) so "upgrade the edge for WireGuard" is a **non-problem, do not re-derive**. IPv6 today: **NH3 WAN live** `2600:1700:b25:c110::48`, **colo none**, **ESH none**. **AT&T delegates one /64 PER REQUEST** (`2600:1700:b25:c11f::/64`) — and the BGW holds the whole `/60`, rationing `c118`–`c11f` one at a time while keeping `c110`–`c117`. So eight /64s exist; UniFi just solicits once. ⛔ **CLOSED 2026-08-24 — operator ruling, do not re-raise:** the BGW has **no IP-passthrough** (operator confirmed, and we have admin on it), so the only route to the other seven is a multi-DUID DHCPv6 client on a VM — which means split-stack routing and rebuilding the entire v6 firewall policy off the UDM. Juice not worth the squeeze. NH3 LANs stay v6-off. A mesh needs a routable **WAN** address, **not** PD. `ana-wg`'s WG socket is **already dual-stack** (`[::]:31337`) → v6 RA needs an address + a v6 port-forward, no WG reconfig. ⚠ UDM legacy `rest/firewallrule` returns **0 rules** (zone-based firewall) — use `v2/…/firewall-policies`; inbound v6 is default-deny and held. All three endpoints will be **dynamic** → extend the existing hostname pattern (`ana-fw`/`nh3.phasefinal.com`) to **AAAA**. Enabled PD on `nh3-iot` to measure, **reverted on operator instruction** (all 5 LANs back to `none`, verified). Also fixed: **`ana-wg` WireGuard key material was world-readable** (`wg0.conf` + `keys/*_priv` + `*_psk` + client `configs/*.conf` at 644) → now 600, dirs 700, service untouched.

(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. - `[2026-08-25]` **`sample_packing` is NOT strictly better than bucketing on this model, and I told the operator it was before brokkr corrected me.** Packing needs FA2 varlen or a block-diagonal mask; FA2 is unavailable here (head_dim 512 > 256 cap), so packing means an explicit 4D mask on EVERY batch. Bucketing produces **78.3% exactly-zero-pad micro-batches** which recover the `is_causal` fast path on the 5 global layers — measured at 9.4% of step time. Packing forfeits that. ⚠ **The conclusion flips under `flex_attention`**, where a block-diagonal mask is just another BlockMask: do not carry "packing is bad" past the backend decision. - `[2026-08-25]` **Merging a tune back toward STOCK to fix overfitting would UNDO the abliteration.** brokkr recommended a 50/50 merge-back, then retracted it himself: the published recipes merge into `google/gemma-4-*-it`, and following that literally re-installs exactly the refusal directions the abliteration removed — silently, because the merged model looks *healthier* on general benchmarks. Any merge-back must target the SAME abliterated base. Wider lesson: **recipe cards are per-checkpoint artifacts, not per-family** — the advice came from a card for a DENSE STOCK 31B applied to a MoE ABLITERATED 26B-A4B, three axes apart on a shared name. - `[2026-08-24]` **AES-GCM on the Anaheim tunnels — impossible, not merely hard.** UniFi's manual site-to-site IPsec implements no AEAD cipher at all: eight GCM spellings rejected `api.err.InvalidPayload` against a passing `aes256` control. Blocks both tunnels since both far ends are UDMs. Accepted enum is `aes128/aes192/aes256/3des` — and 3DES is *slower* (no ARM instructions, 64-bit blocks), so AES-128 is the floor. - `[2026-08-24]` **Pointing the UDM's `wan_dns1` at AdGuard — silently ignored.** It persists and reads back correctly but the LAN-facing forwarder never uses it; proven with fresh uncached ad domains (AdGuard answers `0.0.0.0`, the UDM returned real IPs). Reverted rather than left in place. - `[2026-08-24]` **A multi-DUID DHCPv6 VM to claim NH3's seven unclaimed /64s — declined by the operator.** The BGW has no IP-passthrough (confirmed, we hold admin), so the only route needs re-cabling, split-stack routing and **rebuilding the entire v6 firewall policy off the UDM**. The prefixes are easy; the firewall rebuild is why nobody wants them. Do not re-raise on "there are seven free prefixes". - `[2026-08-23]` **A `HEAD == GITHUB_SHA` assertion in the hrafn CI — added, broke the checkout twice, removed.** It needed the `git` binary (run 9920, exit 127); installing `git` then flipped `actions/checkout@v4` off its **node** implementation onto the git binary, which died on a missing CA bundle (run 9921). A nice-to-have assertion changed the checkout's code path and broke a working pipeline. Removed rather than patched with `ca-certificates` — it guarded a hypothesis that proved wrong. **Do not add `git` to that prereq step.** - `[2026-08-23]` **Repointing `selene-1-mini-8b` at gen's endpoint — proposed by me, correctly overruled.** *"never repoint a named model at a different model's endpoint — that is intentionally misleading."* The trap is that it does not feel like deception; it feels like sparing consumers a migration. That framing is the tell. Role aliases move; model names die with the model and 4xx. - `[2026-08-15]` **Grafted bf16 MTP loads UNINITIALIZED (0% accept) unless `re:^mtp.*` is in the quant-config `ignore`; and W4A16=Marlin (not native FP4) costs ~20% even on decode.** Cost a premature 79 GB delete of a good model (declared desync-dead off the 0%). Lessons: test MTP on bf16 FIRST, isolate before deleting; modelopt 0.43 is dependency-hell for qwen3_5 (list-vs-dict quant_cfg + transformers conflict) — use llm-compressor.

Flipped it (added to `COMFY_CMDLINE_EXTRA`, recreated) → `triton.compiler.errors.CompilationError: ValueError("type fp8e4nv not supported in this architecture. supported: fp8e4b15, fp8e5")` in `comfy_kitchen/backends/triton/quantization.py:145 dequantize_per_tensor_fp8`, failing at **node 5 CLIPTextEncode**. Triton's fp8 dequant kernel targets `fp8e4nv` (Hopper/Ada e4m3); **sm_86 Ampere (A6000) lacks hardware e4m3** → the JIT compile dies. With triton on it grabs the **global** `--fp8_e4m3fn-text-enc` dequant, so every render (fp8 AND int8) dies upstream at the text-encode step — the int8 UNet path never ran, so the convrot-coverage caveat wasn't even the limiter. Reverted cleanly (~15s to healthy, image unchanged `sha256:94afb8ca`, sage intact, prod restored). **The parked cu130 rebuild won't fix it** (e4m3 = hardware format, not CUDA version). **DEFERRED to the Ada refresh** (operator: "ada is coming, we'll optimize then" — Ada sm_89 has native e4m3, so triton's fp8 path should compile there). **Mechanics:** `--enable-triton-backend` is a compose `environment:` var, so toggling it needs `docker compose up -d` (**recreate**), NOT `docker restart` (reuses the baked env, no-ops silently).
