# AGENTS.md — serverAppConfigs Agent Rules
|
||
|
||
## Overview
|
||
|
||
This repository is the single source of truth for the two homelab servers and
|
||
the FrankBook-Pro Mac mini. It tracks the Podman container stacks and the LLM
|
||
inference fleet. One repo, one checkout per host, one deploy script. All
|
||
services run from `/home/dank/serverAppConfigs` on each host (the 2026-08-22
|
||
merge absorbed the former `vllmScripts` repo, history preserved).
|
||
|
||
- **Dankserver** (192.168.0.235) — media/library stack (RomM, Copyparty,
|
||
Calibre-Web, Jellyfin, Plex) plus the `frank-medium` LLM service.
|
||
- **Dankclaw** (192.168.0.143) — AI/search/dev/observability stack (SearXNG
|
||
via Gluetun, ComfyUI, OpenWebUI, Hermes, Gitea, Grafana, Prometheus, Loki,
|
||
Alloy, Pi-hole) plus TWO LLM services: `frank-large` (unsloth llama.cpp prebuilt on
|
||
the gfx1151 iGPU) and `frank-small` (llama.cpp on the RTX 3090). Caddy on
|
||
Dankclaw reverse-proxies both hosts.
|
||
- **FrankBook-Pro** (192.168.0.112) — macOS mini running the *arr stack
|
||
(Prowlarr, Sonarr, Radarr, Lidarr, Readarr, qBittorrent) as quadlets inside
|
||
its podman machine; all egress rides the Gluetun WireGuard netns. Deployed
|
||
via the `frankbook-pro` handler.
|
||
|
||
## Fleet topology (ACTIVE)
|
||
|
||
| Target | Service | Runtime | Model | Port |
|
||
|--------|---------|---------|-------|------|
|
||
| Dankserver | `frank-medium` | vllm-radiance 0.9.3 (rootless Quadlet, image `localhost/radiance-vllm:0.9.3`, gfx1201) | orcarouter Qwen3.8-27B-Uncensored-FP8 (FP8 E4M3 block-wise, 30.9 GB / 7 shards) with the z-lab DFlash2 external drafter (depth 7, live mean accept length 4.24/7 — A/B tested and beats MTP self-speculation on decode: 100.0 vs 85.9 t/s), 2x Radeon AI PRO R9700 in ONE tensor-parallel process (TP=2 over the R4D one-shot allreduce — no RCCL collective; both cards on CPU root ports at Gen5 x8 since the 2026-09-20 ProArt B850-Creator swap), 262144 ctx over up to 8 conversations (auto-sized 384,238-token KV pool = 1.47x the window), fp8 KV, prefix caching, vision | 7770 |
|
||
| Dankclaw | `frank-large` | unsloth llama.cpp b11030 prebuilt (ROCm gfx1151, root systemd unit) | unsloth Qwen3.8-Flash-Next UD-IQ4_XS on the gfx1151 iGPU (Strix Halo LPDDR, 114 GiB GTT), 200000 ctx single stream (1 slot), MTP depth 2 via the explicit `-md` shared-Q8_0 head, text only | 7770 |
|
||
| Dankclaw | `frank-small` | mainline llama.cpp master 37b53fd (root systemd unit) | HauhauCS Gemma4-12B-QAT-Uncensored-Balanced Q4_K_M (BF16 mmproj + MTP assistant sidecar, `draft-mtp,ngram-mod`) on the RTX 3090, 1048576 pool / 4 slots of 262,144, q8_0 KV, the fleet's fastest vision endpoint | 7771 |
|
||
|
||
Retired endpoints (`frank-npu`, and every prior runtime) are in
|
||
the [runbook index](#runbook-index). The full swap history lives in
|
||
`serverAppConfigs-docs/LLM/index.md` — do not grow it here.
|
||
|
||
## Repository Layout
|
||
|
||
- `dankserver/` — compose.yaml + Caddyfile + .env.example for the media stack
|
||
- `dankclaw/` — compose.yaml + Caddyfile + .env.example for the AI stack
|
||
- `shared/` — homepage, Prometheus, Loki, Alloy, SearXNG configs
|
||
- `scripts/` — `deploy.sh` / `deploy-plan.py` / `deploy-remote.sh`, LLM serve
|
||
scripts, systemd units, env tunables, bench harnesses
|
||
- `old/` — retired LLM scripts (reference only)
|
||
- `serverAppConfigs-docs/` — knowledge base (Obsidian vault, OKF format)
|
||
- `tests/` — bats suite + Playwright e2e
|
||
|
||
## Git Workflow
|
||
|
||
All edits flow through git. Never edit files on a remote machine directly.
|
||
|
||
1. **Source** the live config from the target machine
|
||
2. **Commit** the fetched version here (redact secrets into `.env`)
|
||
3. **Edit** locally
|
||
4. **Test** — `./tests/run.sh` must pass
|
||
5. **Commit and push** — origin is Gitea on Dankclaw
|
||
6. **Pull** on the target (`deploy.sh` does this)
|
||
7. **Deploy** — `scripts/deploy.sh` plans and dispatches only changed services
|
||
|
||
## Deployment
|
||
|
||
```
|
||
./scripts/deploy.sh dankclaw
|
||
./scripts/deploy.sh dankserver
|
||
./scripts/deploy.sh dankclaw --service searxng
|
||
./scripts/deploy.sh dankserver --service frank-medium
|
||
./scripts/deploy.sh dankclaw --dry-run
|
||
```
|
||
|
||
The planner maps changed paths to services; the remote runner restarts only
|
||
the selected service and records its revision outside the checkout.
|
||
Documentation-only changes are a no-op. LLM services are selected only by
|
||
their own files — `frank-large`/`frank-small` by their unit/env/serve trio in
|
||
`scripts/`, `frank-medium` by its Quadlet unit, entrypoint and healthcheck under
|
||
`dankserver/frank-medium/` — so
|
||
unrelated
|
||
container changes cannot interrupt inference. Set `FRANK_SUDO_PW` for headless
|
||
runs on a host without passwordless sudo; the value never enters the repo.
|
||
|
||
### Deployment completeness (MANDATORY)
|
||
|
||
A deploy is **not complete** when `deploy.sh` exits green. It requires:
|
||
|
||
1. `./tests/run.sh` — all seams green, and
|
||
2. the Playwright e2e suite (`tests/e2e/run.sh`) — runs **automatically** as
|
||
the `[3/3]` gate at the end of `deploy.sh` against the LIVE fleet; a
|
||
behavior-affecting deploy that fails it exits `DEPLOY INCOMPLETE`. Bypass
|
||
only with `--skip-e2e` in an emergency.

||

||

||

|
||
I -->|no| K[DEPLOY INCOMPLETE]
|
||
```
|
||
|
||
## Boot Persistence & Self-Healing (MANDATORY)
|
||
|
||
Every deployed, working Podman container MUST have a self-healing,
|
||
boot-persistent Quadlet unit. A container that runs only from `compose.yaml`
|
||
or a manual `podman run` dies silently at reboot — rootless Podman does not
|
||
auto-start bare containers, and `restart: unless-stopped` does not survive the
|
||
explicit stop that shutdown performs. Never report such a service as "up".
|
||
|
||
Unit requirements:
|
||
|
||
- **Boot persistence** — `[Install] WantedBy=default.target`, installed to
|
||
`~/.config/containers/systemd/<name>.container`, enabled in the user
|
||
manager, with linger on for the deploy user (`loginctl show-user dank -p
|
||
Linger` → `Linger=yes`).
|
||
- **Self-healing** — `Restart=always` (or `on-failure`) with a short
|
||
`RestartSec`; quadlet health check where the service has one.
|
||
- **Repo provenance** — the `.container` file lives in this repo
|
||
(`<host>/<svc>/quadlet/`), is installed by the deployer, and is covered by
|
||
the quadlet test seam. The host-side unit is generated state; the repo file
|
||
is the source of truth.
|
||
|
||
Before declaring a service deployed: `systemctl --user is-enabled <name>` →
|
||
`enabled`, `is-active` → `active`, and the container answers its health check.
|
||
A running container with no unit is a gap: write the unit, test it, deploy it.
|
||
|
||
This rule exists because reboots found gaps twice (2026-08-26: Caddy as a
|
||
bare compose container never returned; 2026-09-11: five observability
|
||
services had no units). The observability services now have units under
|
||
`dankclaw/observability/quadlet/` and their compose definitions were removed —
|
||
one owner per container name. The stack is **configured and delivering as of
|
||
2026-09-17**: a Grafana datasource and the `llm-fleet` dashboard are
|
||
provisioned from `shared/grafana/provisioning/`, `shared/prometheus/rules/
|
||
llm-fleet.yml` loads 5 alert rules + 1 recording rule, and firing rules are
|
||
delivered: Prometheus → Alertmanager (`dankclaw/observability/quadlet/
|
||
alertmanager.container`, loopback :9093) → host-side Signal relay
|
||
(`scripts/signal-relay.py`, user unit, 192.168.0.143:18093 — the host LAN
|
||
IP, the one bind a container can reach as `host.containers.internal`;
|
||
iptables admits loopback, the host and the podman bridge subnet only) → signal-cli account 318311.
|
||
Prometheus targets read down for structural reasons (HTML-scraped "probes",
|
||
Gitea metrics off); the remedy is a blackbox exporter. See
|
||
`serverAppConfigs-docs/Infrastructure/Observability.md`.
|
||
|
||
## Testing
|
||
|
||
Tests are mandatory before commit (`bats` required on the dev machine):
|
||
|
||
```
|
||
./tests/run.sh
|
||
```
|
||
|
||
Seams: compose validity, env consistency (no leaked secrets), Caddyfile
|
||
validity, quadlet units, docs completeness **including vault link integrity**,
|
||
script syntax (shell + python), LLM unit integrity, LLM secret hygiene,
|
||
deployment flow, service-scoped planning, homepage config/pages/deploy/checker,
|
||
and `e2e_scaffold` — which fails if a Playwright spec file's number prefix is in
|
||
no project, because such a spec silently never runs.
|
||
See `serverAppConfigs-docs/Architecture/Testing Policy.md`.
|
||
|
||
## Secret Rules
|
||
|
||
- Never commit real secrets. The live Gitea DB password and sudo password are
|
||
test-enforced leak checks.
|
||
- `.env` files are git-ignored; commit only `.env.example` with placeholders.
|
||
Exception: `scripts/*.env` LLM tunables (paths and numbers, never
|
||
credentials).
|
||
- Do not document passwords anywhere in the repo. SSH keys are the auth
|
||
mechanism; `FRANK_SUDO_PW` covers headless sudo and never enters the repo.
|
||
- **A token passed as `curl -H "Authorization: Bearer …"` is world-readable.**
|
||
It lands in `/proc/<pid>/cmdline`, so any `ps`/`pgrep -a` on the host prints
|
||
it — that leaked an HF token into a session transcript on 2026-09-16, while
|
||
merely checking whether a download was still running. Pass secrets out of
|
||
band (`curl -K <mode-600 file>` carrying the header, or `HF_TOKEN` in the
|
||
environment for `hf`/`hf_transfer`) and never `pgrep -a` a fetch command that
|
||
carries an auth header.
|
||
|
||
## External Exposure Policy (MANDATORY)
|
||
|
||
Every Caddy-proxied service is either behind the auth chain (Anubis :8923 →
|
||
Authentik embedded outpost) or explicitly internal-only — no public DNS name,
|
||
no vhost. New services default to internal-only until guarded.
|
||
|
||
When guarding a new vhost — provider first, then route:
|
||
|
||
1. Create the outpost proxy provider FIRST (`external_host` = exact vhost URL
|
||
with trailing slash; `internal_host = http://caddy:8017`). If the vhost
|
||
flips first, authenticated traffic hits the outpost error page.
|
||
2. Flip the vhost to `reverse_proxy anubis:8923` with
|
||
`header_up X-Real-Ip {remote_host}`, and add the post-auth
|
||
`@<svc> host <vhost>` handler on the `http://:8017` listener routing to
|
||
the real upstream.
|
||
3. Anubis guard set, Caddy TLS edge, and outpost provider list change
|
||
together in one deploy.
|
||
4. Service-to-service traffic targets internal addresses (`loki:3100`), never
|
||
the public hostname — non-browser clients cannot solve challenges.
|
||
|
||
Exempt categories (document the reason in the vhost comment): the IdP itself
|
||
(`auth.`), git smart-HTTP endpoints, services with their own complete auth.
|
||
|
||
## Deletion & Trash Policy (MANDATORY)
|
||
|
||
Never `rm`. Move deletions into trash so they stay recoverable:
|
||
|
||
1. In-repo files → `.AGENTTRASH/` beside the item's directory.
|
||
2. Elsewhere → dated staging dir `~/.AGENTTRASH/YYYYMMDD-topic`.
|
||
3. List staged items and sizes; wait for explicit user approval to purge.
|
||
|
||
`rm`, `rm -rf`, and `git clean -f` are forbidden without explicit permission.
|
||
`git * --no-verify` is forbidden. The trash is a temporary hold, not an
|
||
archive.
|
||
|
||
## Benchmarking Policy (MANDATORY)
|
||
|
||
**STOP the production service BEFORE benchmarking** — these servers serve
|
||
real users, and a bench beside a live service starves the GPU and corrupts
|
||
results. Use the runtime's own harness: `llama-bench` for every llama.cpp
|
||
endpoint (all three are llama.cpp now). Rolling your own bench
|
||
requires asking first.
|
||
Scratch ports are not used on LLM hosts — a
|
||
test process cannot share the single GPU anyway; validate against the service
|
||
itself.
|
||
|
||
This covers **any GPU experiment, not just benchmarks** — including a bare
|
||
2-rank RCCL/`torch.distributed` probe. On 2026-09-16 one such probe was run
|
||
against the live service "because it only needs 200 MB of VRAM"; the host went
|
||
hard down ~20 minutes later (no ARP reply, 100% ICMP loss from two subnets, no
|
||
recovery — a power cycle was required). A hung AQL dispatch wedging the GPU
|
||
driver is the plausible mechanism, and this host has precedent for going
|
||
unreachable until a power cycle. If an experiment needs GPUs, stop and mask
|
||
first, or use a host that serves nobody. Telling an off machine from a wedged
|
||
one: `ip neigh show <ip>` from a peer — FAILED means off/NIC dead, while a
|
||
merely wedged kernel usually still answers ARP.
|
||
|
||
1. Stop and mask (self-healing would restart it):
|
||
- Dankclaw `frank-large` (root unit, CIRU llama.cpp on the iGPU):
|
||
`sudo systemctl stop frank-large && sudo systemctl mask frank-large`
|
||
- Dankclaw `frank-small` (root unit, llama.cpp on the 3090):
|
||
`sudo systemctl stop frank-small && sudo systemctl mask frank-small`
|
||
- Dankserver `frank-medium` (**rootless Quadlet since 2026-09-20** — the
|
||
system unit is retired, so `sudo systemctl` sees nothing):
|
||
`systemctl --user stop frank-medium && systemctl --user mask frank-medium`
|
||
2. Bench.
|
||
3. Unmask and start; verify `curl http://192.168.0.<host>:7770/health`.
|
||
|
||
**CRITICAL:** never `systemctl disable` a system unit on these hosts — it
|
||
deletes the unit file from `/etc/systemd/system/`, not just the symlink.
|
||
`mask` symlinks to `/dev/null` and is safe/reversible.
|
||
|
||
## Model Config (harness)
|
||
|
||
The harness reaches the fleet through `.omp/agent/models.yml` in the
|
||
operator's home — `/home/blank/.omp/agent/models.yml` on the dev box, which is
|
||
where the harness runs; there is no copy on the servers. Each provider is one
|
||
HOST:PORT; each model `id` is the served alias: `frank-medium` →
|
||
`192.168.0.235:7770`, `frank-large` → `192.168.0.143:7770`, `frank-small` →
|
||
`192.168.0.143:7771`. Per-role routing lives beside it in `config.yml` under
|
||
`modelRoles`.
|
||
|
||
Resolution rules: the default model resolves as a `defaultProvider` +
|
||
`defaultModel` pair (the provider must serve the model); a subagent override
|
||
uses a bare model `id`, which resolves only when unique across providers. Two
|
||
ports on one host need two providers — the file cannot express "same host,
|
||
different port".
|
||
|
||
When renaming a service, retiring an endpoint, or moving a model: update the
|
||
provider block, model `id`, `contextWindow`, `maxTokens`, `input` in
|
||
`models.yml`, then fix every `modelRoles` entry that named the old endpoint —
|
||
a role pointing at a provider the file does not define fails at call time. As
|
||
of 2026-09-20 both `frank-small` and `frank-medium` accept images
|
||
(`input: [text, image]`) — frank-medium's checkpoint serves vision through the
|
||
Gemma4 merge path with no separate mmproj, verified on held-out synthetic
|
||
images; `frank-large` remains text-only because its unsloth deployment loads no
|
||
vision projector (the F16 mmproj is on disk, one env flip away). Note also that
|
||
the reasoning channel differs by runtime: llama.cpp endpoints emit
|
||
`reasoning_content`, vLLM emits `reasoning`.
|
||
There is **no audio**
|
||
input anywhere in the fleet: that capability left with the FLM NPU endpoint on
|
||
2026-09-11.
|
||
|
||
### frank-large — unsloth llama.cpp Qwen3.8-Flash-Next UD-IQ4_XS (Dankclaw, ACTIVE)
|
||
|
||
The unsloth llama.cpp prebuilt `app-b11030-mix-5ff778e` (ROCm gfx1151,
|
||
`/home/dank/GitPackages/unsloth-llama-b11030/`, bundles its own ROCm runtime —
|
||
no host SDK gate, no venv) as a **root systemd unit** (`scripts/
|
||
frank-large.service`, `User=dank`), serving
|
||
`unsloth/Qwen3.8-Flash-Next-GGUF:UD-IQ4_XS` (87.3 GiB main GGUF, three HF
|
||
split parts concatenated, + a 2.6 GiB MTP head, all sha256-verified) on port
|
||
7770 from the gfx1151 iGPU. One stream, 200,000 ctx (`PARALLEL_SLOTS=1`,
|
||
operator's requested shape; the trained window is 262,144), MTP depth 2
|
||
(`SPEC_DRAFT_N_MAX=2`, the model card's default), reasoning extracted to
|
||
`reasoning_content`, and **no vision projector** (the F16 mmproj is on disk,
|
||
`ENABLE_VISION=0` — one env flip to enable). It replaced the CIRU v4.4.1
|
||
Orca runtime, which had replaced halogen-flash-server.
|
||
|
||
The runtime is the first with an MTP graph for the qwen4exp architecture
|
||
(stock ggml-org mainline has none), so the unsloth prebuilt is the
|
||
llama.cpp-compatible choice. The MTP head is loaded via an **explicit
|
||
`-md`**: sidecar auto-discovery does not search the `mtp/` subfolder, and
|
||
without it `--spec-type draft-mtp` silently runs at the main model's speed.
|
||
The serve script (`scripts/serve-frank-large.sh`) validates binary → main
|
||
GGUF → MTP head and exits with a pointer message if any is missing, then
|
||
`exec`s `llama-server` with `--jinja --alias frank-large --chat-template-
|
||
kwargs '{"preserve_thinking":true}'` (Qwen3.8's template needs this to
|
||
carry thinking blocks across turns; a request-level value still wins).
|
||
|
||
The iGPU addresses **114 GiB** (the GTT aperture over the shared LPDDR,
|
||
`gtt_total` in `/sys/class/drm/card1/device/`; `rocm-smi`'s 2 GiB "dedicated"
|
||
is not the budget). The 87.3 GiB model is mmap'd in with `-ngl 999`; budget
|
||
at 200k ≈ 100 GiB (weights + MTP head + KV + buffers), leaving ~14 GiB of
|
||
aperture headroom. The n-gram embedding (PLE) is inside the GGUF — no
|
||
external PLE payload or pager, unlike the CIRU Orca packaging.
|
||
|
||
Fetch: `scripts/download-frank-large-unsloth.sh` (resumable, each part
|
||
verified against its LFS sha256 fetched live from the Hub tree API, then the
|
||
assembled GGUF against `SHA256SUMS`; `--verify-only` re-checks).
|
||
|
||
Runbook: `serverAppConfigs-docs/LLM/frank-large-unsloth-qwen38-flash-next.md`.
|
||
Rollback: [[frank-large-ciru-orca]] (payload and runtime intact on disk).
|
||
|
||
### frank-small — llama.cpp on the RTX 3090 (Dankclaw, ACTIVE)
|
||
|
||
Mainline llama.cpp master `37b53fd` (CUDA build with
|
||
`-DGGML_CUDA_FA_ALL_QUANTS=ON`) as a **root systemd unit** (repo
|
||
`scripts/frank-small.service`, `relink_unit`ed into `/etc/systemd/system/`),
|
||
serving `HauhauCS/Gemma4-12B-QAT-Uncensored-HauhauCS-Balanced` at Q4_K_M.
|
||
The MTP head is a SEPARATE assistant file (`mtp-gemma-4-12B-it.gguf`, 4
|
||
nextn layers) loaded via `--model-draft`; the draftless **ngram-mod**
|
||
matcher chains behind it in the same `--spec-type` value. BF16 mmproj,
|
||
port 7771, q8_0 KV, `CTX_SIZE=1048576` / `PARALLEL=4`
|
||
(four FULL 262,144-token slots — the measured card ceiling), batch
|
||
**8192/1024**, greedy default. Deployed flags are in
|
||
`scripts/frank-small.env`; the serve script refuses to start if the
|
||
weights, the projector, the sidecar or the binary are missing.
|
||
|
||
Verified at deploy (2026-09-17): `/v1/models` reports `frank-small`; a
|
||
chat completion returns content plus `reasoning_content`; a tool call
|
||
returns `tool_calls`; an image request is answered from the projector;
|
||
an `input_audio` WAV transcribes verbatim. Post-tuning live numbers at
|
||
max length: pp@254k ~965 t/s, tg@253k 226–302 t/s with ~94% draft
|
||
acceptance; idle 23,300 MiB of 24,576. The throughput sweep (and why
|
||
ubatch 2048 OOMs the draft's pp buffer, and why draft depth 4 + poll
|
||
100 is WORSE at long ctx) is tabled in the runbook.

### frank-medium — radiance TP=2, DFlash2 drafter (Dankserver, ACTIVE)
|
||
|
||
vllm-radiance **0.9.3** (`localhost/radiance-vllm:0.9.3`, rootless **Quadlet**
|
||
`dankserver/frank-medium/quadlet/frank-medium.container`) serving
|
||
`orcarouter/Qwen3.8-27B-Uncensored-FP8` (FP8 E4M3 block-wise 128×128, dynamic
|
||
activation quant, 30.9 GB / 7 shards) with the **z-lab DFlash2 external
|
||
drafter** (`num_speculative_tokens: 7`, live mean accept 4.24/7) in **one
|
||
tensor-parallel process across both R9700s** (`--tensor-parallel-size 2`).
|
||
262,144 ctx, `--max-num-seqs 8`, chunk 8192, fp8 KV, prefix caching, GPU fill
|
||
0.98, **no KV-memory pin** — the pool auto-sized to 384,238 tokens (1.47× the
|
||
full window; the DFlash2 drafter's 2.1 GiB costs the pool vs MTP's 461,540).
|
||
DFlash2 was A/B tested against MTP self-speculation on this checkpoint and
|
||
wins on decode (100.0 vs 85.9 t/s) — see the runbook. Tools via `qwen3_coder`,
|
||
reasoning via `qwen3` (the field is `reasoning`, not llama.cpp's
|
||
`reasoning_content`), vision through the Gemma4 merge path, chat template
|
||
Qwen-Sharp v22.4.0 (froggeric, repo-tracked at `dankserver/frank-medium/`,
|
||
terse system prompt by default).
|
||
|
||
**The entrypoint is quantization-aware.** `radiance-entrypoint.sh` reads
|
||
`quantization_config.quant_method` from the checkpoint's `config.json` and
|
||
serves the plain FP8 path (no MXFP4 patches, `--quantization fp8`,
|
||
`ROCM_AITER_UNIFIED_ATTN`, the DFlash2 drafter) or the MXFP4 patch-and-serve
|
||
path (the DFlash2 external drafter). A checkpoint swap is therefore four quadlet
|
||
env vars (`SNAP`, `SPEC_METHOD`, `SPEC`, `KV_MEM`) — the deploy handler reads
|
||
the serving shape from the quadlet and gates on the right assets. The MXFP4
|
||
checkpoint (`just1moremodel/Qwen3.8-27B-Uncensored-MXFP4-awq` + the z-lab
|
||
DFlash2-FP8 drafter) remains on disk as the rollback target. Full swap
|
||
process + toolchain: [[frank-medium-model-swap]].
|
||
|
||
**TP=2 runs because the board changed.** The predecessor board (TUF GAMING
|
||
B650-E) put card #2 behind chipset bridges advertising `AtomicOpsCap: Routing-`
|
||
and no collective could be dispatched there. The ProArt B850-Creator WiFi NEO
|
||
routes both cards to CPU GPP root ports (`00:01.1 → 03:00.0`,
|
||
`00:01.3 → 07:00.0`, Gen5 x8, every hop `Routing+`, both endpoints `ReqEn+`).
|
||
The collective in use is vLLM's **R4D one-shot allreduce**, which never touches
|
||
RCCL (TheRock RCCL has no gfx1201 device code; the Ubuntu RCCL 2.27 build does,
|
||
and that is what `scripts/build-llama-rdna4.sh GGML_HIP_RCCL=ON` links).
|
||
|
||
**Measured, not assumed** (`scripts/bench-conversation.py`, 10 real prompts,
|
||
max_tokens 512, greedy, salted per arm, service stopped between arms):
|
||
radiance TP=2 95.8 t/s decode geomean / 0.21 s TTFT / 259.4 t/s burst-4, vs the
|
||
llama.cpp layer split's 45.7 / 0.72 / 71.7 and llama.cpp `--split-mode tensor`'s
|
||
30.5 / 0.71 / 54.3. Honest caveat: the arms also differ in quantization (MXFP4
|
||
vs Q8_0), so part of the margin is the quant, not the parallelism. Re-measured
|
||
against production after deploy: 92.4 t/s, 0.22 s, 248.9.

|
||
verified, idempotent fetch), `scripts/swap-frank-medium.sh` (generate
|
||
manifest → download → detect quantization → edit the quadlet → deploy). The

|
||
`serve-frank-medium.sh`) is archived in `scripts/.AGENTTRASH/

|
||
moved the installed unit symlink there rather than `systemctl disable`, which
|
||
would delete it. The deploy handler reads `SNAP`/`SPEC_METHOD` from the
|
||
quadlet, gates on the image tag + the checkpoint's `config.json` (drafter only
|
||
for `dflash`, `libr4d` only for `mxfp4`/`quark`), then waits for :7770 and
|

gates on `/health`.

||
|
||
## Key Lessons Learned
|
||
Durable operational lessons from the fleet's history. Full detail in the
|
||
linked runbooks.
|
||
|
||
**PCIe / multi-GPU**
|
||
|
||
- **RCCL collectives need PCIe atomics on every participating GPU.** RCCL's
|
||
kernels carry a hidden hostcall-buffer parameter; ROCr refuses to dispatch
|
||
them when the device has no atomics, and the failure surfaces as
|
||
`hipErrorIllegalState` ("the operation cannot be performed in the present
|
||
state") from `hipLaunchKernel`, not as anything that names atomics. The
|
||
value is consumed at driver probe time, so writing the AtomicOp Requester
|
||
bit with `setpci` at runtime changes nothing. Check the *chain*:
|
||
`lspci -vv -s <gpu>` and every upstream bridge must show
|
||
`AtomicOpsCap: Routing+` (a `Routing-` bridge is a hardware wall), and the
|
||
endpoint's Device Control 2 (`setpci -s <gpu> CAP_EXP+28.w`) must have bit
|
||
6 set. AMD desktop platforms put one card on CPU root ports (atomics work)
|
||
and the rest behind the chipset (usually not) — that asymmetry is what
|
||
blocked frank-medium's TP=2. A one-card collective proves nothing: NCCL
|
||
short-circuits at `world_size=1`.
|
||
- **That wall was physical, and it was fixed on 2026-09-20 by a board swap.**
|
||
Both paths that put two cards on CPU root ports were: an M.2→PCIe x4 riser
|
||
into a *CPU-attached* M.2 slot, or a board whose CPU lanes bifurcate to
|
||
x8/x8. dankserver took the second: **ASUS ProArt B850-Creator WiFi NEO**,
|
||
`PCIEX16_1` + `PCIEX16_2` at x8/x8 Gen5 on root ports `00:01.1` / `00:01.3`,
|
||
every bridge now `Routing+` and **both endpoints `ReqEn+`** — the exact
|
||
precondition the old test plan named. Bandwidth was never the constraint (a
|
||
27B TP=2 allreduce at batch 4 is ≈10 MB per token-step, ≈1.4 ms at Gen4 x4
|
||
and under 0.4 ms at Gen5 x8).
|
||
**Proven on the same day.** vLLM's R4D one-shot allreduce runs TP=2 here and
|
||
frank-medium serves on it; llama.cpp's RCCL path was built too
|
||
(`GGML_HIP_RCCL=ON`) and its tensor mode measured — real collective, slower
|
||
shape. Note the collective choice matters: TheRock's RCCL builds lack gfx1201
|
||
device code (`invalid device function`), which is why R4D is the path vLLM
|
||
uses at all. Evidence matrix and the measured three-arm verdict:
|
||
[[Dual-R9700-Cooperation]].
|
||
- **When a GPU collective dies, read the runtime, not the framework.** The
|
||
message that identified the cause came from `AMD_LOG_LEVEL=3`
|
||
(`Pcie atomics not enabled, hostcall not supported` → `AQL dispatch
|
||
failed!`), not from vLLM or RCCL. `AMD_LOG_LEVEL` costs one env var and
|
||
prints the failing HIP call with its return code.
|
||
- **The software path that puts both cards on ONE model without a collective:
|
||
llama.cpp's layer split.** On the old board vLLM could not do it in any of its
|
||
parallelisms — TP needs an allreduce, PP needs the same p2p primitive, and both
|
||
died on the card that could not dispatch an RCCL kernel. `--split-mode
|
||
layer` in llama.cpp needs no
|
||
collective: layers are distributed in order and only the boundary activation
|
||
crosses PCIe, once per forward pass. Measured here: 1991 t/s prefill /
|
||
18.8 tok/s decode layer-split, against 272 / 26.3 tensor (butterfly
|
||
fallback).
|
||
This was what `frank-medium` ran until 2026-09-20, when the board swap made
|
||
collectives legal and radiance TP=2 beat it on every axis (95.8 vs 45.7 t/s
|
||
decode, 0.21 vs 0.72 s TTFT, 259 vs 72 t/s burst-4) — see
|
||
[[frank-medium-radiance-mxfp4]]; the llama shape is the rollback target
|
||
[[frank-medium-llamacpp-dflash2]].
|
||
- **Layer split is also the cross-vendor answer — and `-ot` is what cannot be
|
||
combined with it.** On Dankclaw (2026-09-16) a CUDA 3090 + Vulkan iGPU layer
|
||
split ran a real two-device graph: `-dev CUDA0/Vulkan1 -sm layer -ts 0.15/0.85`
|
||
held 14,994 MiB on the 3090 and gave 27.2 tok/s with 268.5 t/s prefill at 64k
|
||
depth (iGPU alone: 25.8 / 231.8). What does NOT work is per-tensor placement
|
||
across devices: `--override-tensor <group>=<device>` sets
|
||
`has_tensor_overrides()`, a REQUIRED term of the scheduler's
|
||
`pipeline_parallel` flag (llama-context.cpp:433 — the only place in the tree
|
||
that reads it), and that flag is what sets `n_copies` in
|
||
`ggml_backend_sched_new`; with `n_copies == 1` a pre-allocated weight on a
|
||
non-primary device has no backend and the graph aborts (`ggml-backend.cpp:941`,
|
||
reported with the leaf's own op name `(NONE)`). `=CPU` is the only override
|
||
target that works, because the CPU backend is last in the list. Pure Vulkan
|
||
changes nothing here — the gate is the override, not the driver mix. See
|
||
[[x4-pair-experiment]].
|
||
- **A host↔3090 link at x4 measures 6.72 GB/s, and that is a design
|
||
constraint, not a detail.** `pcie-link-test.cu` on Dankclaw (2026-09-16,
|
||
services stopped): pinned H2D 6.72 GB/s, D2H 6.60 GB/s — 85 % of the Gen4 x4
|
||
ceiling — with async no better than sync and pageable within 1 % of pinned,
|
||
i.e. the copies are link-limited rather than staging-limited (the usual
|
||
"pageable costs 2x" rule does not apply here). The card is x16-capable and the
|
||
Strix Halo port beneath it is x8-capable (`LnkCap: 16GT/s, Width x8` on
|
||
`00:03.1`), so the x4 lives in the adapter or cable; the link idles at
|
||
2.5 GT/s x4 and trains up under load. Consequence for any engine that
|
||
*streams* weights across it: a 3 MiB slab costs 474 us, and a 111 GiB A3B
|
||
model needs ~1.70 GiB of active experts per token ⇒ **3.7 tok/s** (4.6 with a
|
||
20 % resident cache), against **20.46 tok/s** for the same model with the
|
||
experts *computed* in host RAM by llama.cpp (`-ot exps=CPU`, whence the link
|
||
carries activations only) and 25–26.5 on the iGPU. Streaming over PCIe loses;
|
||
computing in RAM does not care. FreeToken — expert LRU in host RAM, exactly
|
||
this streaming shape — also loads only modelopt block-FP8 safetensors for
|
||
`qwen3_5_moe`, so a Q4_K_M GGUF is unloadable there before bandwidth is even
|
||
the question. See [[x4-pair-experiment]].
|
||
|
||
|
||
**ROCm / GPU**
|
||
|
||
- **Layer split was the deployed shape on both multi-device llama.cpp services,
|
||
for two different reasons.** On Dankserver it was the *only* way both R9700s
|
||
served one model (no collective could be dispatched on card #2) until the
|
||
2026-09-20 board swap; frank-medium now runs radiance TP=2 instead. On a
|
||
RCCL-less fork build it is also the fast one: tensor parallel falls back to
|
||
a butterfly allreduce and collapses prefill ~7x (measured 271.8 vs 1991 t/s).
|
||
Pin the spec-decode drafter to one device — an unpinned draft under tensor
|
||
mode aborts the KV build, and on a layer split the natural home is the card
|
||
that ends up holding the target's last layers.
|
||
- **Bundling a ROCm runtime next to a llama.cpp binary: `cp -r SRC DST/` is a
|
||
trap.** With a missing `DST`, cp creates `DST` as a copy of `SRC` and drops
|
||
one directory level. rocBLAS and hipBLASLt look for their device code at a
|
||
fixed depth (`../lib/rocblas/library`, `../lib/hipblaslt/library/<arch>`),
|
||
and the flattened copy fails at *request* time, not load time: the engine
|
||
reads the weights, answers `/health` and dies on the first completion with
|
||
`Cannot read .../TensileLibrary.dat: No such file or directory for GPU arch
|
||
: gfx1201`. Declare the destination, then copy the contents.
|
||
- **mmap must stay on** for the big-PLE models: `--no-mmap` forces the
|
||
~50 GiB PLE table into anonymous memory → silent cgroup kill, dmesg is the
|
||
only evidence. mmap pages ARE page cache. Never pin the PLE tensor with
|
||
`-ot` (23 → 13.4 t/s).
|
||
- **HIP reads bare env vars** `TEMP`, `HOST`, `GPU_MAX_HEAP_SIZE`. Serve
|
||
scripts export env files with `set -a`, so a tunable named `TEMP` leaks
|
||
into HIP (`TEMP=1.0` sent the JIT cache to path `1.0` and segfaulted every
|
||
load, fixed 2026-08-13 by renaming to `TEMPERATURE`). Never name a tunable
|
||
these; check with
|
||
`strings /opt/rocm-*/lib/libamdhip64.so.* | grep -xE "TEMP|HOST|GPU_MAX_HEAP_SIZE"`.
|
||
- **`-DGGML_CUDA_FA_ALL_QUANTS=ON` is required** for q8_0 KV + flash
|
||
attention on CUDA builds; without it prefill collapses ~12x (95 vs 1300+
|
||
t/s, measured 2026-08-17).
|
||
- **Flash-Next MTP heads do not load on any current loader** — they need full
|
||
per-layer `blk.<il>.hc_attn_norm.weight` and ship only `blk.48` (verified
|
||
3x). Don't re-attempt without new loader support.
|
||
- **QSA flash-attn assert:** `GGML_ASSERT(a-type == GGML_TYPE_F32)` on
|
||
qwen4exp needs `scripts/patches/qwen4exp-qsa-f32-mask.patch` — but only on
|
||
the agentionai FAST layer set; the kingjones STRIX set works unpatched.
|
||
- **GPU budget on Dankclaw is the GTT aperture (~114 GiB), not the
|
||
rocm-smi "dedicated" figure.** The Radeon 8060S (gfx1151) reports
|
||
116,732 MiB (`llama-server --list-devices`;
|
||
`gtt_total=122402963456` in `/sys/class/drm/card1/device/`). The older
|
||
"64 GiB, SVM-backed" lesson was already stale — the CIRU Orca predecessor
|
||
held 92.6 GiB of weights on the iGPU. `free`/`dmidecode` show the
|
||
CPU-side carve-out — intentional, do not change.
|
||
|
||
**Load / crash diagnosis**
|
||
|
||
- Model load is slow (minutes cold); health returns 503 while loading; do
|
||
not kill the process. `deploy.sh` waits up to 20 minutes (`LLM_WAIT`). On
|
||
halogen, the FIRST request after a (re)start can go silent ~45–60 s
|
||
(health `engine_unresponsive`, 503s) and then self-recovers — do not
|
||
restart over it.
|
||
- Crash-loop procedure: (1) `journalctl -u <svc> -n 100` + kernel line via
|
||
`journalctl -k` (segfault at address 8 in `libamdhip64` = NULL unref in
|
||
HIP); (2) run serve script, then raw binary — different outcome isolates
|
||
the env file; (3) `gdb -batch -ex run -ex "bt 25" --args bash
|
||
scripts/serve-<svc>.sh` — llama-server buffers stdout and loses the log
|
||
tail on SIGSEGV; trust gdb, not the log; (4) `amdgpu: SVM mapping failed`
|
||
spam is a symptom, not a root cause.
|
||
- Journal signatures: client abort logs `W srv stop: cancel task, id_task =
|
||
N`; natural stop logs only `slot release` with `truncated = 0`. The server
|
||
never preempts a running generation; excess tasks queue when slots are
|
||
busy.
|
||
|
||
**Host memory / swap**
|
||
|
||
- Swap resize ordering: create and `swapon` the replacement BEFORE `swapoff`
|
||
of the old one, or live pages must land in RAM that `MemAvailable`
|
||
overstates. Dankclaw swap (64 GiB at `/swap.img`, fstab-driven) protects
|
||
the co-tenants, not frank-large — pinned weights don't swap, and paging
|
||
the KV pool is worse than the OOM it prevents.
|
||
- Host swap state is invisible to `deploy.sh` (no repo file) — check
|
||
`swapon --show` before reasoning about headroom.
|
||
|
||
**Runtime-specific guards**
|
||
|
||
- **Kairic Edge** (if ever re-deployed): the pinned CK commit needs
|
||
`third_party/composable_kernel/include/ck/config.h` generated manually
|
||
(untracked; `git clean` removes it), and its greedy-argmax fastpath rejects
|
||
non-greedy requests and reasoning budgets. Re-test chat before production.
|
||
- **FastMTP sidecar**: build must be commit `4df29be4` + the HauhauCS patch;
|
||
stock binaries fail the draft load with a tensor-shape mismatch.
|
||
|
||
**llama.cpp serving**
|
||
|
||
- **MTP is a property of the FILE, not of the flags.** The `-mtp` GGUF build
|
||
carries the head as `blk.<n>.nextn.*` (`qwen35.nextn_predict_layers = 1`);
|
||
`--spec-type draft-mtp` then sets `load_mtp`, and the draft context runs on
|
||
the MAIN model's weights (`shares_model`), so there is no second copy of a
|
||
12 GiB model in VRAM and no `-md` argument. The plain build has no MTP
|
||
tensors at all, and pointing `--model-draft` at the file would load it twice.
|
||
- **What can be chained, and what cannot.** `--spec-type a,b` builds every
|
||
enabled implementation and chains drafting through them, in a fixed internal
|
||
order (ngram types first, then the drafters — CLI order is irrelevant). The
|
||
gate is `ctx_dft`: **draftless** types (the ngram family) are added
|
||
unconditionally, while `draft-mtp`, `draft-dflash`, `draft-dspark` and
|
||
`draft-eagle3` all require a draft CONTEXT. So a chain may hold one
|
||
context-backed drafter plus any number of ngram types — `draft-dflash,ngram-mod`
|
||
is legal and measured (2.6x the drafter alone on prompt-echo traffic, byte-
|
||
identical to it on prose at the fleet's 48/64 window) — but
|
||
`draft-mtp,draft-dflash` dies at load: *"context type MTP requested but model
|
||
doesn't contain MTP layers"*, because MTP builds its context against whatever
|
||
model the draft context holds. Two context-backed types cannot share one
|
||
process, and MTP's head only loads when MTP **is** the draft model.
|
||
- **A drafter's KV scales with the TARGET's context, and its window policy
|
||
decides how much that costs.** The draft context is built with
|
||
`cparams.n_ctx = llama_n_ctx(ctx_tgt)` (`common/speculative.cpp`) — there is
|
||
no flag to cap it — so a drafter that declares NO sliding window caches the
|
||
whole window on whatever device `--spec-draft-device` names. Swapping DFlash2
|
||
(`dflash.attention.sliding_window = 2048`, ~40 MiB of draft KV) for DSpark
|
||
(no window; 5 layers x 2 x 8 kv heads x 128 dim x 2 B = 20 KiB per position,
|
||
so **5.0 GiB at 262144**) put ROCm1 at 33.9 GB of 34.2 GB and killed the
|
||
FIRST draft graph capture with `ROCm error: out of memory` — after the model
|
||
had loaded and `/health` had answered. Read `sliding_window` out of the
|
||
drafter's GGUF header before sizing any spec-decode deployment, and prefer a
|
||
skewed `-ts` over a context cut when the full window matters. The pair was
|
||
swapped DFlash2 -> DSpark -> DFlash2 in one day (2026-09-16) and the round
|
||
trip moved the balance point FOUR layers (~4.3 GiB of headroom, 40:25 ->
|
||
36:29), which is the practical size of the effect. See
|
||
[[frank-medium-llamacpp-dflash2]].
|
||
- **`--ubatch-size` has an OPTIMUM on this stack, not a plateau — and its
|
||
compute buffers land about TWICE as heavy on the card that holds the output
|
||
layers and the drafter.** Measured on frank-medium 2026-09-16 at the deployed
|
||
shape (262144 over two slots, a 64k prefill measured at 64k depth,
|
||
`scripts/bench-batch-ubatch.sh`): prefill runs 1046 tok/s at ubatch 256, 1068
|
||
at 384, **1193 at 512 (the peak)**, 1135 at 768, 1152 at 1024, 1151 at 1280,
|
||
1165 at 1536, 1148 at 1792 and 1078 at 2048. Both ends lose — below 512 the
|
||
SMs are not saturated, and 2048 is 10 % off the peak — and 512 -> 1536 costs
|
||
ROCm0 1.30 GiB and ROCm1 2.41 GiB to go 2.4 % SLOWER. The logical
|
||
`--batch-size` does not matter: 2048 through 8192 land within 2 % of each
|
||
other at a fixed ubatch and use identical VRAM. Decode never moves at all
|
||
(15.88 tok/s at depth 65536 on every cell). Because the buffers are
|
||
asymmetric, a split balanced at one batch is unbalanced at another: 512 ->
|
||
1536 shifted frank-medium's balance by a layer, so 36:29 became 35:30.
|
||
Re-measure the balance after changing the batch. (8192/2048 failed to allocate
|
||
its 2020 MiB pp buffer here under the DSpark drafter, when ROCm1 had 0.08 GiB
|
||
free. That was a CONTIGUITY failure, not a total-bytes one, and no totals
|
||
model — the sweep's or the seam's — can see it.)
|
||
- **One `-ts` step is one LAYER, and a hybrid stack's layers are not the same
|
||
size.** qwen35 is 16 x (3 Gated DeltaNet + 1 Gated Attention), so a step is
|
||
worth ~0.43 GiB on a DeltaNet boundary and ~1.43 GiB on a full-attention one
|
||
(0.45 GiB of weights plus ~1.0 GiB of its own f16 KV at 262144) — both
|
||
measured on frank-medium. Balance by measurement, never by interpolating
|
||
between two splits; an affine fit reproduces the deployed point and overstates
|
||
the gaps in between. `tests/frank_medium_unit.bats` encodes that fit as a
|
||
gate. See [[frank-medium-llamacpp-dflash2]].
|
||
- **ngram-mod prints no startup banner.** The load log shows the drafter's
|
||
`adding speculative implementation 'draft-dflash'` and nothing at all for the
|
||
matcher, so a chain can look unengaged while it is working. Identify it
|
||
behaviourally (`draft_n` > 0 only where text repeats) or by the per-task
|
||
`draft acceptance = ... mean len = ...` line. It costs no VRAM (a 64 MiB
|
||
host-RAM hash table) and its window decides which traffic it can see: too
|
||
short and it proposes on ordinary prose fragments, which costs verification
|
||
without acceptance.
|
||
- **`--jinja` is what `tools` needs.** On 2026-09-16 a subagent died with
|
||
`500 tools param requires --jinja flag`, from the ik_llama.cpp runtime that
|
||
then served frank-large: every tool-using agent on that endpoint was broken
|
||
and the failure read like a model fault. Mainline llama.cpp 0.4.1 defaults
|
||
`--jinja` on and the serve script pins it; halogen also accepts `tools` and
|
||
returns `tool_calls`. Check tool support before routing a role at an endpoint.
|
||
- **Quantized KV on CUDA needs `GGML_CUDA_FA_ALL_QUANTS=ON`** — the same
|
||
option and the same ~12x prefill collapse described in the ROCm note above.
|
||
f16 KV needs nothing; frank-small ran f16 for that reason until
|
||
2026-09-17, when `build-cuda` was rebuilt with the option ON so the
|
||
endpoint could take q8_0 KV.
|
||
- **llama-bench separates a LIST with `/` and SWEEP values with `,`.** Both
|
||
`-dev` and `-ts` follow this: `-dev CUDA0,Vulkan1` is two *single-device*
|
||
configurations, never one two-device run, and `-ts 0.85,0.15` is two sweep
|
||
values each becoming `[0.85, 0, …]` / `[0.15, 0, …]`, i.e. device 0 takes
|
||
everything. Write `-dev A/B -ts x/y`. This artifact produced a wrong fleet
|
||
conclusion on 2026-09-16 — "CUDA + Vulkan cannot serve one model", with two
|
||
bogus OOMs that were really "all 111 GiB on the 24 GiB card" — and the bench
|
||
table's own `dev` column was printing the truth the whole time. Any
|
||
placement-dependent number needs an independent check: sample the other
|
||
device's memory (`nvidia-smi`) while the run is loaded.
|
||
- **A model's own template can REJECT the harness's thinking level.** Qwen3.8's
|
||
template accepts only `xhigh`, `medium` and `low` for `reasoning_effort` and
|
||
raises on anything else — HTTP 500, not a clamp — so the harness's levels
|
||
must be folded onto that set in `models.yml` (`compat.reasoningEffortMap`).
|
||
A role whose level is unmapped fails on its FIRST request, and the failure
|
||
names Jinja, not the model: every subagent on `frank-small` died with
|
||
`Unexpected reasoning effort high` until `high: xhigh` was added on
|
||
2026-09-16. Halogen accepts the wider set, so the two entries legitimately
|
||
differ.
|
||
|
||
**Ops**
|
||
|
||
- Never `pkill -f` a pattern that appears in your own command line — it kills
|
||
your ssh session. Use `pkill -x <exact-name>`.
|
||
- Both hosts allow passwordless sudo for the deploy user. Use plain `sudo` in
|
||
committed scripts (no `echo pw | sudo -S`); `FRANK_SUDO_PW` covers hosts
|
||
without it.
|
||
- ComfyUI on Dankclaw runs with **GPU access** (`/dev/kfd` + `/dev/dri` via
|
||
`AddDevice`, `GroupAdd=keep-groups`, plus the udev rule that makes those nodes
|
||
world-writable — user-unit spawns carry no supplementary groups). It must NOT
|
||
pass `--cpu`: the gfx1151 ROCm wheels exist and the unit's `--cpu` era ended
|
||
2026-09-16, when a stale device-less container was found restarted 9,146
|
||
times (`RuntimeError: No HIP GPUs are available`).
|
||
- SearXNG outbound traffic must stay on the Gluetun tunnel; do not move its
|
||
ports off the gluetun service.
|
||
- `amd_iommu=off` on Dankclaw (bought 13–16 % prefill for frank-large,
|
||
2026-09-11) permanently retired the XDNA2 NPU: the driver's SVA/PASID bind
|
||
needs an enabled IOMMU (`/dev/accel/accel0` fails `err=-19`). Revert path
|
||
in `serverAppConfigs-docs/LLM/dankclaw-iommu-translation-off.md`.
|
||
- Rootless Quadlet containers run with `--replace --rm`: `podman logs` covers
|
||
only the CURRENT instance; history across recreations lives in
|
||
`journalctl --user -u <name>.service`. Read rootless storage WITHOUT sudo
|
||
(per-user storage — `sudo podman logs` finds nothing).
|
||
- **A dead rootless podman pause process breaks ALL container management on the
|
||
host, and `podman system migrate` panics in 5.7.0.** Symptoms: every `podman`
|
||
command fails with `invalid internal status … could not find any running
|
||
process`, every container start fails binding podman's bridge addresses
|
||
(`Error starting server failed to bind udp listener on 10.89.x.1:53: Cannot
|
||
assign requested address`), and every `Restart=always` quadlet loops. Container
|
||
storage is intact; what is gone is `/run/user/<uid>/libpod/tmp/alive` (a UUID
|
||
token, not a pid) and the rootless netns holding the bridges — deleting the
|
||
stale token is not enough, and `podman system migrate` segfaults in
|
||
`teardownNetworkBackend`. Repair: **reboot** (`/run/user` clears and all 28
|
||
quadlets return on their own — check `Linger=yes` and `WantedBy=default.target`
|
||
first). Seen 2026-09-16, hours into heavy GPU work on the same host — but the
|
||
trigger is NOT established (`journalctl -k` recorded no OOM kill; the kernel
|
||
had no other word on it). Treat the pause process as host state that can die
|
||
for its own reasons, and reach for the reboot when it does.
|
||
- **A container cannot reach a `Network=host` service at the host's LAN IP.**
|
||
netavark DNATs *published* ports only: from a bridge container
|
||
`192.168.0.143:<published>` answers while `192.168.0.143:<host bind>` and the
|
||
gateway `10.89.1.1` are both refused. Use `host.containers.internal`
|
||
(169.254.1.2). This is what 502'd `hermes.franksdank.cloud` until the Caddyfile
|
||
upstream was changed on 2026-09-16 (its vhost comment had claimed the LAN IP
|
||
was open from that bridge — it never was).
|
||
- **A `*.gguf` filter misses mradermacher's payloads: large quants ship as
|
||
`.partNofM` fragments.** `mradermacher/Qwen3.8-Flash-Next-Uncensored-i1-GGUF`
|
||
carries Q4_K_M (37.00 + 37.00 + 36.97 = 110.97 GiB) and Q4_K_S (35.00 + 35.00
|
||
+ 34.09 = 104.09 GiB) as parts, while the smaller rungs (Q2_K, Q3_K_*, IQ3_*,
|
||
IQ4_XS) are single files. Fetch the parts, verify each against the Hub's LFS
|
||
sha256, concatenate in numeric order — that is how the deployed 111 GiB file
|
||
was assembled. Listing the Hub tree and filtering `endswith(".gguf")` makes
|
||
Q4_K_S look like it does not exist.
|
||
- **A fetch script must `-f` and verify, or it reports success on an access
|
||
error.** `curl -o FILE URL` exits 0 on HTTP 401/403 and writes the error body
|
||
as the "artifact": a gated repo yielded three 153-byte shards with identical
|
||
sha256 values and a cheerful `DOWNLOAD_DONE` in 20 seconds for 104 GiB. Use
|
||
`-f`/`--fail-with-body`, compare each file's byte count to the Hub's declared
|
||
size, and check the LFS sha256 — `scripts/download-frank-medium-gguf.sh`
|
||
already does all three; ad-hoc fetches tend not to. Gated repos (e.g.
|
||
`orcarouter/Qwen3.8-Flash-Next-Uncensored-GGUF`, same 104.09 GiB Q4_K_S)
|
||
return 403 even with the host's HF token until that account accepts the gate.

|
||
|
||
## Why
|
||
|
||
Direct edits on the remote drift from version control, and future agents
|
||
won't know what changed. Git is the single source of truth. The two workloads
|
||
share two hosts, one Caddy, and one Gitea; one repo keeps them in one
|
||
history.
|
||
|
||
## Summary
|
||
|
||
| Context | Action |
|
||
|---------|--------|
|
||
| Editing a compose/Caddyfile/serve script | **Through git** — fetch, commit, edit, test, push, pull, deploy. Never edit on the remote. |
|
||
| Config exists only on remote | **Pull it into the repo first** — commit the fetched version (redacted) before editing. |
|
||
| Unstaged local changes | **Commit or discard** — check `git status` before starting work; ask if unsure. |
|
||
| Deploying a committed change | **`scripts/deploy.sh <target>`** — pushes, pulls ff-only, plans, dispatches, health-checks. |
|
||
| Container without a Quadlet unit | **Give it one** — boot-persistent, self-healing `.container` via git. |
|
||
| Benchmarking | **Stop and mask the service first**, bench, unmask, restart, verify health. |
|
||
| Deleting a file | **Move it to trash** — `.AGENTTRASH/` (in-repo) or `~/.AGENTTRASH/YYYYMMDD-topic`. Never `rm`. |
|
||
| Tests exist | **Run them** — verify tests pass after every change. Do not commit failing tests. |
|
||
| Real secrets | **Never commit** — host `.env` files; `.env.example` holds placeholders only. |
|
