chore(plex): bump pin to 1.43.5.11029-6bf8af3f0-ls329 (latest)

ls329 is the newest build on the linuxserver channel and Plex 1.43.5.11029
is their newest release; the live pin (ls325 / 1.43.4.10903) is two Plex
releases behind. Digest-verified at pin time: the tag's manifest digest
equals the registry's current 'latest' (sha256:8f655bad...e9e2334), the
same law the page records. Quadlet restart runs PMS's usual one-minor
schema migration on first boot; the deployer's /identity HTTPS gate
tolerates the first-boot migration up to 600 s.

Rollback: revert this commit (one line).

+# 127.0.0.1 (the old rootless unit used 0.0.0.0 only because container loopback
+# was not host loopback; under Network=host they are the same address, so the

 #
-# THE UI PORT EXISTS ON PURPOSE. Alloy's UI listens on the container's own
-# 127.0.0.1 by default and cannot be moved from the config file (alloy 1.x
-# refuses the ui block), so the compose service had no reachable health
-# endpoint at all: the homepage status card for alloy reported "down"

-# below therefore moves the UI to the container's wildcard address and the
-# port is published on host loopback only, which puts alloy in the same class
-# as the other three: reachable from the host, by Caddy over the private
-# network, and by nothing off-host. Alloy has no authentication, which is
-# exactly why it is not published wider.
-#
-# SOURCES. The host journald socket and the host log/container-storage trees

+#
+# Install path on dankclaw: ~/.config/containers/systemd/cadvisor.container
+# Unit name: cadvisor.service (container name: cadvisor)
+#
+# WHY THIS EXISTS. The app stack is ~34 rootless Podman containers and until

+# host (node_exporter) and the LLM engines. cadvisor reads the host cgroup
+# tree and exports container_cpu_* / container_memory_* per container.
+#
+# THE LOAD-BEARING FLAG IS --cgroupns=host. Podman starts every container in a
+# PRIVATE cgroup namespace, so an exporter container sees only its OWN cgroup
+# subtree: cadvisor exported a single root series until this flag was added,
+# then it walked the whole tree (996 per-container series measured 2026-10-20).
+# The quadlet unit name is carried in the cgroup path — app.slice/<name>.service/
+# libpod-payload-<hex> — so Prometheus relabels that path into a `container`
+# label (shared/prometheus/prometheus.yml, cadvisor-dankclaw job) and no
+# libpod/podman socket is needed to name containers.
+#
+# BINDING. cadvisor has no per-interface listen flag (unlike node_exporter's
+# --web.listen-address), so it binds 0.0.0.0 INSIDE its own network namespace.
+# The bridge PublishPort is what keeps the unauthenticated endpoint off the
+# host's other interfaces: it publishes exactly loopback (host-local probes and
+# the deployer's health gate) and this host's LAN address (Prometheus, a bridge
+# container, reaches a host-published port at its LAN address — the same netavark
+# rule node-exporter relies on, only here the port really is published).
+#
+# It is rootless on purpose: dank owns the app containers' cgroups, so a
+# rootless cadvisor reads every one of them; root would buy nothing here.

+#      Fix: point it at default-provider-authorization-implicit-consent, the
+#      flow every other provider in this instance already uses.
+#   2. The `grafana-email-scope` ScopeMapping's expression was the bare string
+#      `user.email`. authentik merges a scope mapping's result into the token as
+#      a MAPPING: a returned dict adds its keys as claims; a returned string is

+"""gpu-exporter: unified per-GPU metrics for a mixed AMD/NVIDIA host.
+
+Emits the `gpu_*` Prometheus families the host-system dashboard graphs:
+
+    gpu_utilization_percent  gpu_memory_used_bytes  gpu_memory_total_bytes
+    gpu_temperature_celsius  gpu_power_watts
+
+each labelled {gpu, vendor, model}. The scrape job adds `host`.
+
+Two sources, both host-native — no container, no GPU passthrough:
+
+  * AMD (R9700s, the 8060S iGPU, the Raphael display GPU): the amdgpu sysfs tree.
+    Utilization comes ONLY from gpu_busy_percent — amd-smi reports gfx_busy_inst
+    as N/A on gfx1201 (verified 2026-10-20). VRAM is already bytes, temperature
+    is milli-degrees, power is micro-watts. Crucially power1_average is EMPTY on
+    the R9700s, so those cards legitimately have no gpu_power_watts line; a
+    missing file becomes an ABSENT metric, never a fabricated 0 that a dashboard
+    would plot as a real reading.
+
+  * NVIDIA (the RTX 3090 on Dankclaw): one `nvidia-smi --query-gpu` CSV. On
+    Dankserver there is an nvidia-smi binary but no NVIDIA GPU, so the command
+    fails; that is tolerated and simply yields no NVIDIA series.
+
+Default mode prints one scrape to stdout and exits (the test harness, and any
+`service ... --oneshot` one-off). `--serve` binds the HTTP endpoint for
+Prometheus; it binds EXPLICITLY (loopback + the host LAN address), never a
+wildcard, matching node-exporter's posture on these boxes.

+# Domain Docs
+
+How the engineering skills (`/grill-with-docs`, `/domain-modeling`,
+`/improve-codebase-architecture`, `/to-spec`) should consume this repo's design
+vocabulary when exploring the codebase.
+
+## Before exploring, read these
+
+- **`GLOSSARY.md`** at the repo root
+- **`docs/adr/`**: read ADRs that touch the area you're about to work in
+
+If either doesn't exist, **proceed silently**. Don't flag their absence; don't
+suggest creating them upfront. `/domain-modeling` (reached via
+`/grill-with-docs` and `/improve-codebase-architecture`) creates them lazily
+when terms or decisions actually get resolved. As of 2026-10-20 neither exists;
+this page is the pointer, not a promise.
+
+## Ownership against this vault
+
+This repo already carries `serverAppConfigs-docs/` — the operational knowledge
+base and, per repo law, the owner of operational facts (endpoint shapes, Eras,
+Laws, runbooks). `GLOSSARY.md` / `docs/adr/` hold **design vocabulary and
+decisions**. Where a term is defined in both, the vault page that owns the fact
+wins — one fact, one owner. A glossary entry restating an endpoint number is
+the bug, not the second source.
+
+## Use the glossary's vocabulary
+
+When output names a domain concept (an issue title, a refactor proposal, a
+hypothesis, a test name), use the term as defined in `GLOSSARY.md`. Don't drift
+to synonyms the glossary explicitly avoids.
+
+If the concept you need isn't in the glossary yet, that's a signal: either
+you're inventing language the project doesn't use (reconsider) or there's a
+real gap (note it for `/domain-modeling`).
+
+## Flag ADR conflicts
+
+If output contradicts an existing ADR, surface it explicitly rather than
+silently overriding:
+
+> _Contradicts ADR-0007 (…), but worth reopening because…_

+
+# Issue Tracker
+
+Issues and specs for this repo live as Gitea issues in `dank/serverAppConfigs`
+on `http://192.168.0.143:3000` (Dankclaw). There is no `gh`/`glab` CLI here —
+the door is the GitHub-compatible REST API driven with `curl`. The
+mattpocock-lineage skills (`/triage`, `/to-tickets`, `/to-spec`, `/wayfinder`)
+read this page as their tracker contract. The git workflow around issues and
+PRs (branches, PR-only merges, attribution footer) is owned by
+[[Deployment Flow]]; this page owns only the API shape.
+
+## Auth
+
+The token lives in the git credential file `~/.config/secrets/gitea`: one
+line in git-credential URL form, `http://user:TOKEN@192.168.0.143`. Extract it
+without echoing:
+
+```bash
+tok=$(sed -nE 's#^http://[^:/@]+:([^@]+)@192\.168\.0\.143.*#\1#p' ~/.config/secrets/gitea | head -1)
+```
+
+**A token on a command line is world-readable in `/proc/<pid>/cmdline`** (the
+same leak class AGENTS.md records for HF tokens). Never pass it with `-H` —
+put it in a mode-600 curl config and pass `-K`:
+
+```bash
+cfg=$(mktemp); chmod 600 "$cfg"
+printf 'header = "Authorization: token %s"\n' "$tok" > "$cfg"
+# ... every curl below uses -K "$cfg"; rm -f "$cfg" when done
+```
+
+**GETs also accept HTTP Basic; writes do not** — a POST/PATCH with Basic auth
+is refused with `422 {"message":"token is required"}` (measured 2026-10-20).
+Use the `Authorization: token` header for everything.
+
+## Conventions
+
+`$API=http://192.168.0.143:3000/api/v1/repos/dank/serverAppConfigs`
+
+- **Create an issue**: `curl -s -K "$cfg" -X POST -H 'Content-Type: application/json' -d "$(jq -n --arg t "$TITLE" --rawfile b "$BODY" '{title:$t, body:$b}')" $API/issues`
+- **Read an issue**: `curl -s -K "$cfg" $API/issues/<number>` (fields: `number`, `title`, `body`, `labels[].name`, `state`)
+- **List issues**: `curl -s -K "$cfg" "$API/issues?state=open&limit=50"` — add `&labels=<id>` to filter
+- **Comment**: `curl -s -K "$cfg" -X POST -d "$(jq -n --rawfile b "$BODY" '{body:$b}')" $API/issues/<number>/comments`
+- **Apply labels**: `POST $API/issues/<number>/labels` with `{"labels":[<label-ID numbers>]}` — Gitea wants numeric label **IDs**, not names; resolve them from `GET $API/labels` (see [[Triage Labels]] for which labels exist)
+- **Remove a label**: `DELETE $API/issues/<number>/labels/<label-id>`
+- **Close**: `PATCH $API/issues/<number>` with `{"state":"closed"}`
+- **Blocking relationships**: this instance has no native sub-issues or dependencies — put `Part of #<parent>` / `Blocked by: #<n>, #<n>` lines at the top of the child body. A ticket is unblocked when every listed blocker is closed.
+- **Attribution footer (repo law)**: every issue body you open ends with `cwd: <working directory> · session: <omp session id>` — full rule in [[Deployment Flow]].
+
+**PRs as a request surface: no.** Issues and PRs have separate number spaces on
+Gitea; a bare `#42` is an issue, a PR is spelled "PR #42".
+
+## When a skill says "publish to the issue tracker"
+
+Create a Gitea issue as above.
+
+## When a skill says "fetch the relevant ticket"
+
+`GET $API/issues/<number>` and read `title` + `body` + `labels[].name` +
+comments.
+
+## Wayfinding operations
+
+Used by `/wayfinder`. The **map** is a single issue labelled `wayfinder:map`,
+holding the Notes / Decisions-so-far / Fog body.
+
+- **Map**: create an issue, apply the `wayfinder:map` label (create it via `POST $API/labels` `{"name":"wayfinder:map","color":"#6f42c1"}` if missing).
+- **Child ticket**: an issue carrying `Part of #<map>` at the top of its body, plus a `wayfinder:<type>` label (`research`/`prototype`/`grilling`/`task`).
+- **Blocking**: the `Blocked by:` body line (see Conventions).
+- **Frontier**: list open issues (`?state=open`), drop any with an open `Blocked by` target or an assignee; lowest `number` wins.
+- **Claim**: `POST $API/issues/<n>/assignees` with `{"assignees":["dank"]}` — actually assign it or it stays in the frontier; the session's first write.
+- **Resolve**: post the answer as a comment, `PATCH` to `closed`, then update the map issue's body (GET → edit Decisions-so-far → PATCH) with a context pointer.

+# Triage Labels
+
+The mattpocock-lineage skills speak in terms of five canonical triage roles.
+This page maps those roles to the actual label strings used in this repo's
+tracker ([[Issue Tracker]] owns the API shape).
+
+| Label in mattpocock/skills | Label in our tracker | Meaning                                  |
+| -------------------------- | -------------------- | ---------------------------------------- |
+| `needs-triage`             | `needs-triage`       | Maintainer needs to evaluate this issue  |
+| `needs-info`               | `needs-info`         | Waiting on reporter for more information |
+| `ready-for-agent`          | `ready-for-agent`    | Fully specified, ready for an AFK agent  |
+| `ready-for-human`          | `ready-for-human`    | Requires human implementation            |
+| `wontfix`                  | `wontfix`            | Will not be actioned                     |
+
+When a skill mentions a role (e.g. "apply the AFK-ready triage label"), use the
+corresponding label string from this table. Edit the "Label in our tracker"
+column to match whatever vocabulary you actually use.
+
+## Instance quirks (Dankclaw Gitea)
+
+- Labels are applied by **numeric ID**, never by name: `POST /issues/<n>/labels`
+  with `{"labels":[<id>]}`; resolve names via `GET /labels`.
+- The repo also carries the pre-existing `human-only` label from the manual era
+  (e.g. the podcast-destination issues). `ready-for-human` maps to itself; the
+  `(HUMAN ONLY)` title prefixes on existing issues stay as they are — the label
+  is what the skills read.
+- An issue with **no** triage label is simply untriaged; absence is not a state.

+The consequence that changed designs: **a rootless container's menu of local model
+endpoints was only `frank-tts` (container DNS, same network) and `frank-archon` (LAN

+
+```
+podman run --network pasta --network dankclaw_default …
+Error: cannot set multiple networks without bridge network mode, selected mode pasta

+so the only shape that makes such an endpoint nameable is **moving it onto
+`dankclaw_default`** (`FRANK_DRAGOON_NETWORK` in `scripts/frank-dragoon.env`,
+2026-10-19). For frank-dragoon that is not an exposure change: the engine's
+unauthenticated token port binds the container's **own loopback**

 The app's own login stays on behind the chain. It is not redundant: publishing the API on loopback does **not** hide it from this host's other containers, which can dial `open-notebook:5055` by name on `dankclaw_default`. The chain decides *who from outside* gets in; `OPEN_NOTEBOOK_PASSWORD` decides what anything that already reached the port may do.

One shared password therefore means **one shared workspace** — the guard chain can gate the door but cannot partition the data, and Authentik identity is never consumed. Multi-user is *approved but unbuilt* upstream (issue **#712**, "design phase, targeted post-v2"); OIDC/SSO was declined for now (**#607** closed).

-**No embedding model is deployed, and saving a note is where that shows up.** Every note save submits an `embed_note` command that fails in the worker with `No embedding model configured. Please configure one in the Models section.` The note itself is stored and readable; semantic search, source ingestion and notebook-context questions stay dead until something serves `/v1/embeddings`. Podcast generation from `content` does not need embeddings, which is why renders work today. The cheapest door is **halogen's NPU lane, not a new endpoint**: `qwen3-embedding-0.6b` is already in the catalog of the image `frank-dragoon` runs and answers `/v1/embeddings` on the same port (1024 unit-length floats; the instruct prefix goes in the text, and `check_embedding_ctx_length=False` for LangChain). What enabling it costs — the accel device, the host XRT mount, and the fabric-clock hold that GPU+NPU co-run requires — is on [[frank-dragoon]]; after that, the embedding row still has to clear the reachability rule above.
+**Embeddings run on the XDNA2 lane — provisioned 2026-10-19.** `qwen3-embedding-0.6b` answers `/v1/embeddings` at `http://frank-dragoon-halogen:8731/v1`, the flash container's own bridge address; a container name on `dankclaw_default` resolves to `10.89.1.39`, plain RFC1918, so it clears the URL guard that ruled out `host.containers.internal` above. The lane's shape (one program, the token ceiling, what it costs the Flash model) is owned by [[frank-dragoon]]; the two shapes that bite on the app side are open-notebook's own:
+
+- **`PUT /api/models/defaults` stores the record ID, not the name.** `"default_embedding_model": "qwen3-embedding-0.6b"` is accepted and echoed back, and then every embed dies in the worker with `Model with ID qwen3-embedding-0.6b not found`. The value has to be the row's `model:…` id — the other defaults in that same object are ids, so mirror them.
+- **`POST /api/embed` answers 500 while succeeding.** Upstream's `EmbedResponse.command_id` declares `str` and the worker hands it a `RecordID`, so FastAPI raises on serialization *after* the vector is written. The truth is the worker line `Successfully embedded note … in 0.19s`, never the HTTP code. Saving a note (`POST /api/notes`) submits `embed_note` by itself, so that route is only needed to backfill old rows.
+
+Proof from the app's own paths, 2026-10-19: `POST /api/models/{id}/test` → `Embedding dimensions: 1024`; two notes with nothing in common, then `POST /api/search` with `type: "vector"` (the enum is `text` or `vector`; the score field is `similarity`) — "a yellow waterbird beside a glowing beacon tower" put the grebe note at **0.659** and the boiler note at 0.292, and "quarterly depreciation schedule for industrial boilers" inverted it to **0.906** / 0.318. Embed cost 0.19–0.43 s per note. Semantic search, source ingestion and notebook-context questions are live; podcast generation never needed any of it.
 
 **Secrets never go in a command line.** The API's bearer token *is* `OPEN_NOTEBOOK_PASSWORD`, and a `-H "Authorization: Bearer …"` argument is world-readable in `/proc/<pid>/cmdline`; put it in a mode-600 curl config and pass `-K`:

-## Why Alloy and not Promtail
+## Why root (the load-bearing decision)
 
-Promtail reached end-of-life on 2026-03-02 and Grafana Labs directs new installs to Alloy. This stack uses Alloy from day one: no Promtail config or unit has ever existed in this repository (`git log -S promtail` over the whole history returns no commit that added one; the compose-era service of the same name was already Alloy — `dankclaw/observability/quadlet/alloy.container:6-7`).
+A rootless Alloy delivered **zero** lines, silently and with a green health
+check. Two independent causes, both proven on the host 2026-10-20:
+
+1. **The journal is not readable by a rootless container.** The files are
+   `root:systemd-journal 0640` (`group:adm`, `other::---`). Even bind-mounted, a
+   rootless container has no supplementary groups, so opening them returns
+   `DENIED`. `loki.source.journal` then sees an empty view and the counter just
+   sits at 0 — no error logged.
+2. **Container logs live in the *user* journal, not `ctr.log`.** The rootless
+   Quadlet containers log via the journald driver into `user-1000.journal`; the
+   old file globs (`/var/lib/containers/.../ctr.log`, `/var/log/containers/*.log`)
+   point at a root-storage layout that does not exist here.
+
+**Root fixes both at once.** As root the container opens every journal file
+under the machine-id directory — `system.journal` *and* `user-1000.journal` —
+so a single `loki.source.journal` carries host services and the rootless
+containers' logs together. Validated with a throwaway root probe before writing
+the unit: **31,825 journal lines read, 26,966 pushed to Loki in 20 s, zero
+drops**, and Loki's label set went from empty to populated.
+
+### The two mounts that make it work
+
+- **`/etc/machine-id` (ro) — load-bearing.** `sd_journal` locates the journal
+  directory by the *local* machine id. Without it the container opens nothing and
+  the journal source reads exactly 0 lines — silently, health green. This single
+  mount is the whole difference between a working and an empty pipeline; do not
+  remove it. (A root probe without it reads 0; with it, 31,825.)
+- **`Network=host`.** Loki publishes `127.0.0.1:3100` (loopback only). No bridge
+  container — rootless or root — can reach the host's loopback, so Alloy must
+  share the host network to push to `127.0.0.1:3100`. Consequence: the UI binds
+  `127.0.0.1` directly (no `PublishPort`), so it stays loopback-only as before.
 
 ## Configuration
 
-`shared/alloy/config.alloy` is the source of truth:
-
-- Reads journald logs from the host's `/run/systemd/journal/socket`, labelled `job="systemd-journal"` (`shared/alloy/config.alloy:20-26`).
-- Reads container logs from two globs: `/var/lib/containers/storage/overlay-containers/*/userdata/ctr.log` (`job="podman"`) and `/var/log/containers/*.log` (`job="containers"`) (`config.alloy:29-35`).
-- Forwards everything to `http://loki:3100/loki/api/v1/push` by container name on `dankclaw_default` (`config.alloy:13-17`).
+`shared/alloy/config.alloy` is the source of truth — one `loki.source.journal`
+(labelled `job="systemd-journal"`) forwarding to the loopback `loki.write`
+endpoint. There is deliberately **no** container-file source: container stdout is
+in the journal.
 
 ## Volumes
 
 | Container path | Host path |
 |----------------|-----------|
-| `/etc/alloy` | `/opt/alloy/config` |
-| `/run/systemd/journal/socket` | host journald socket (read-only) |
-| `/var/log` | host logs (read-only) |
-| `/var/lib/containers` | podman storage (read-only) |
+| `/etc/alloy` | `/opt/alloy/config` (ro) |
+| `/etc/machine-id` | host machine id (ro) — **required** |
+| `/run/systemd/journal/socket` | host journald socket (ro) |
+| `/var/log/journal` | persistent journal files (ro) |
+| `/run/log/journal` | runtime journal files (ro) |
 
-## The UI port is published on purpose
+## The UI stays on loopback
 
-Alloy's UI listens on the container's own `127.0.0.1:12345` by default, and Alloy 1.x refuses to configure the `ui` service from a config block ("service ui does not support being configured", `shared/alloy/config.alloy:8-10`). Under compose that meant **no reachable health endpoint at all**: the homepage status card for alloy read `down` continuously and a deploy had nothing to wait on. The unit therefore passes `--server.http.listen-addr=0.0.0.0:12345` (`dankclaw/observability/quadlet/alloy.container:46`) and publishes `127.0.0.1:12345` (`alloy.container:47`, confirmed by `ss -ltnp` 2026-10-18) — same posture as the other three: reachable from the host and from Caddy's network, and from nothing off-host. Alloy has no authentication, which is exactly why it is not published wider. The homepage card probes that same loopback port (`shared/homepage/services.json:233`).
-
-## Delivery state (2026-10-18): healthy, shipping nothing
-
-The unit is `active`, the container reports `healthy`, the log says `Alloy is ready`, and the pipeline carries no data at all. Measured on 2026-10-18:
-
-- `curl -s http://127.0.0.1:12345/metrics` → `loki_source_journal_target_lines_total{component_id="loki.source.journal.journal"} 0` and `loki_source_file_files_active_total{component_id="loki.source.file.containers"} 0`. The journal source logs no error; the counter simply never moves. The journal files it would have to read through the `/var/log` bind are `root:systemd-journal 0640` with an ACL (`ls -l /var/log/journal/64a287d7…/` 2026-10-18).
-- Both file globs were refused at start (`journalctl --user -u alloy`, 2026-10-18T08:25:27Z), verbatim: `failed to create source, skipping … component_id=loki.source.file.containers error="failed to tail file, stat failed: stat /var/lib/containers/storage/overlay-containers/*/userdata/ctr.log: permission denied"` and the same message for `/var/log/containers/*.log: no such file or directory`.
-- Downstream that means Loki holds zero streams — `GET /loki/api/v1/labels` returns `{"status":"success"}` with no `data` — see [[Loki]].
-
-No fix is claimed here: the unit, the config and the push endpoint are all correct as written, and the gap is source-side access (and a Kubernetes-style glob that does not exist on this host). Anyone closing it should re-check the two counters above, not the health status — health is exactly what hides this failure mode.
+Alloy 1.x refuses to configure the `ui` service from a config block, so the UI
+address is set on the command line instead. Under the old rootless unit that
+meant `0.0.0.0` inside the container plus a published `127.0.0.1:12345`; under
+`Network=host` the listen-addr is `127.0.0.1:12345` directly — the host's
+loopback, reachable from the host and from nothing off-host. Alloy has no
+authentication, which is exactly why it is never published wider. The homepage
+card and the deploy health gate both dial `http://127.0.0.1:12345/-/healthy`.
 
 ## Gotchas
 
-- The journald socket mount is required for journal scraping.
-- Container log paths differ between docker (`/var/lib/docker/containers`) and podman (`/var/lib/containers/storage/...`); point the config at the right one per host.
-- One Alloy per host; do not run a single instance that tries to reach both hosts' logs.
-- The unit `Wants=`/`After=` `loki.service`: without a reachable Loki the write client fails and the pipeline backs up.
+- **No `/etc/machine-id` mount ⇒ silent zero.** The health check still passes.
+  This is the failure mode that hid the broken pipeline; check
+  `loki_source_journal_target_lines_total` and the Loki label query, never
+  `/healthy`.
+- **`After=loki.service` is gone.** Alloy is on the system manager; Loki is a
+  rootless user unit — a system unit cannot order against a user unit. Alloy
+  retries its push until Loki answers, so ordering is unnecessary.
+- **The image must be in the ROOT store.** The deployer builds rootless and
+  mirrors (`mirror_image_to_root`); a `Pull=never` root quadlet with only a
+  rootless tag fails at create.
+- One Alloy per host; do not run a single instance that tries to reach both
+  hosts' logs.

This is **DB state, not repo-managed**: a blueprint re-import or rebuild reverts the stage to `0`, so re-run the script after one.

+  exports a single series (measured 2026-10-20: 1 series off, 996 on). cadvisor
+  names nothing itself — the libpod socket resolved only 2 of 34 rootless
+  containers — but the quadlet unit name is carried in the cgroup path
+  (`app.slice/<name>.service/…`), so `prometheus.yml` relabels that path into a
+  `container` label. Network and filesystem are NOT exported for these containers
+  (no netns/classid attribution under the host-PID layout), so the dashboard
+  graphs only CPU, memory and OOM and does not fake the rest.
+* **Per-GPU metrics: the `host-system` GPU panels (added 2026-10-20; live after
+  `deploy.sh <host> --service gpu-exporter`).** `scripts/gpu-exporter.py` is a
+  host-process user unit on BOTH hosts — not a quadlet, because it reads the host's
+  own DRM sysfs and shells to `nvidia-smi`, neither of which a container can do
+  without GPU passthrough. It reads each AMD card's `gpu_busy_percent` /
+  `mem_info_vram_*` / `hwmon temp1_input` and one `nvidia-smi --query-gpu` CSV, and
+  emits unified `gpu_*` families (utilization %, VRAM used/total bytes, temperature
+  °C, power W) labelled `gpu` / `vendor` / `model`, with `host` added by the scrape
+  job. Two laws: **absent means absent, never a zero** — the R9700s expose no sysfs
+  `power1_average`, so they carry no `gpu_power_watts` line at all (only NVIDIA and
+  the Dankclaw 8060S iGPU report power); and it binds loopback + the host LAN, like
+  node-exporter, never the wildcard. The dashboard graphs util/VRAM/VRAM-%/temp/power.
+* **Logs: fixed in code, awaiting deploy.** The pipeline shipped nothing because
+  a rootless Alloy cannot read the `0640` journal files, and the container-log
+  globs point at a root-storage layout that does not exist here. The fix is built

 sequence stops producing entirely and then re-prefills from token 0, which is a
 stall, not sludge.
 
-Knobs, in the order worth trying them (radiance GUIDE §4.5):
+**Split the step ledger before choosing a knob.** Three counters decide which mechanism you are
+looking at, and none is a rate: `engine_step_seconds_decode_total / engine_steps_decode_total` is
+the mean **decode-only** step, and `(step_seconds_total − step_seconds_decode_total) /
+(steps_total − steps_decode_total)` is the mean **chunk step** (a chunk alone, or a chunk with
+decode rows beside it). On frank-archon's live 1.8.1 shape that pair is **15.5 ms against 166 ms**,
+with 4.7 % of the steps holding 34 % of the step time. Decode-only steps themselves move only
+14.1 → 16.4 ms between a prefill-free minute and a heavy one, and the lagged buckets stay flat: so
+a decode-rate collapse on that box is **step time sharing**, and the eviction/residency story is
+worth ~10 % of one step — not a lever.
 
-- `--prefill-interleave N` — after a chunk step taken beside decoders, the next N
-  steps carry decode rows only and admit nothing. Decoders keep their cadence; the
-  prompt pays that in TTFT. Counts as `engine_steps_held_total`.
-- `--busy-prefill-chunk MODE` — the chunk's share of a step that has other work:
-  `auto` (default) reserves a row plus the draft window per decode row behind it and
-  an eighth of the budget per waiting prefill/request, `off` lets the chunk take the
-  whole step (admission never runs while it does), `N` pins the share. Never under
-  the prefill stager's smallest pass — the startup line names it, and below it every
-  routed layer reads its pooled experts synchronously, which costs the prefill far
-  more than sharing saves. Counts as `engine_prefill_chunks_capped_total`.
-- `--max-num-batched-tokens` — the blunt rung, and the only one older pins have. The vendor's own
-  curve prices **halving the shared chunk at roughly a fifth of prefill throughput** (a 48-layer MoE
-  at 200k on two cards — knob pricing, not this endpoint's number, so treat it as the order of
-  magnitude a chunk decision costs). Raising it past the checkpoint interval buys nothing and loses
-  expert residency to the arena.
-- `--prefill-span N` — the inverse trade: a *lone* prefill carries N intervals a step while every
-  shared step is planned at a smaller shared budget, which on an expert-tiered box lends that arena
-  back to the expert slab. The vendor's own measurement says the win is **long-prompt-only**: nothing
-  at short prompts, a large TTFT gain at the far end of the window.
+**Four traps in the PromQL above.** Learn them before trusting a bucket:
+- **Latency is `vllm:`, cadence is `radiance:`.** The TTFT / inter-token / per-output-token / e2e
+  histograms and the running/waiting gauges exist only under the vLLM compatibility prefix; preemption
+  is `vllm:num_preemptions_total` (the counter) while `radiance:num_requests_preempted` is the
+  *instant* depth. A `radiance:`-only query finds no latency and no preemption, and reads as "the
+  endpoint never stalls anyone".
+- **The tps gauges are 1 s decayed windows, batch-pooled.** Per-stream rate is
+  `decode_tokens_per_second / vllm:num_requests_running`. With a 15 s scrape, a 120 s step samples one
+  scrape in eight — use step ≤ 30 s for a bucket table.
+- **Every counter resets at a restart and the metric set changes with the build.** Prove the window is
+  one shape (`up`, or the first sample of a counter that only the current build exports) before
+  ranking buckets; frank-archon's 48 h window straddled two containers, and one bucket's "collapse"
+  turned out to belong entirely to the older one.
+- **A 2-minute mean step time dilutes the chunk.** The sharp variable is the phase ratio in the query
+  above, never `step_seconds/steps` — 4.7 % of steps cannot move a mean that is 95 % decode.
 
-Two traps. **The arena/slab coupling makes a shared step doubly expensive on an
-expert-tiered shape**: the full-plan arena takes VRAM the resident expert slab would have had, so the
-decode rows inside that step also read experts over the link — a smaller shared budget helps twice.
-And **re-check
-`prefix_hit_rate` / `prefix_evictions` after any chunk change**: the arena and the KV
-pool are the same memory, and the failure looks like turn two taking as long as turn
-one.
+Three instruments the PromQL above cannot reach:
 
-Availability is a version question, not a config question: `--busy-prefill-chunk` and
-`--prefill-interleave` are absent from older pins — prove it on the running container
-(`podman exec <c> <binary> --help | grep -iE "prefill|chunk"`), never from the vendored
-tree, and check the source clone's depth before dating a flag from `git log -S`
-(a `--depth 1` clone reports its own tip for every search).
+- **The engine's own step-detail histograms (`prefill_steps_duration`, `prefill_step_tokens`,
+  `token_queue_wait`) are exported but reach no target**, and the arena / expert slab / heat engine /
+  prefill stager have **no metric at all**. Per-request forensics mean `curl localhost:7770/stats` on
+  the endpoint's own host — same phase counters plus `preemptions` (the count), the chunk geometry,
+  and the expert/link byte totals. `/diagnostics` answers "is the *box* the limit" in one call:
+  configuration drift, the VRAM split, each card's link chain and clocks, findings with fixes.
+- **`prefix_hit_cut_tokens_total` measures prefill load you created for yourself.** On a hybrid
+  (linear + paged) model a prefix hit reuses only as far as the last **linear-state** checkpoint, so
+  cached tokens are replayed as prefill and stall decoders for it; frank-archon ran 38 % of all its
+  prefill tokens that way, every `prefix_hit_cuts_total` labelled `reason="no_snapshot"`. A high
+  prefill rate is not always a client that sends new tokens. Retention is `--checkpoint-policy` -
+  exactly three names, `geometric-backoff` (default), `tip-only`, `keep-all`, one owner:
+  [[frank-archon]].
+- **Bucket the arriving request too** — `histogram_quantile` over
+  `vllm:time_to_first_token_seconds_bucket` by the same prefill series. The decode gauge only sees
+  sequences that are already running; the one waiting for its first token pays the same steps and
+  shows in no decode number.
 
-Run on: [[frank-archon]] — the census was taken on its 3-slot radiance 1.0.13 era (budget 2048 =
-interval 2048); the live 1.8.1 shape carries the two chunk knobs. The measured census and the verdict
-for this fleet's shape are that page's.
+Knobs, in the order worth trying them (radiance GUIDE §4.5; the pinned source is the referee):
+
+- `--prefill-interleave N` — after a chunk step taken beside decoders, the next N steps carry decode
+  rows only and admit nothing. **The knob that acts on the measured mechanism.** Decoders keep their
+  cadence; the prefilling prompt pays in TTFT and an arriving request waits out the held steps.
+  Counts as `engine_steps_held_total` — if that counter is zero, nothing is protecting anyone.
+- `--busy-prefill-chunk N` — pins a shared chunk's share of the step. **`auto` is a prefill-speed
+  setting, not decoder protection:** it reserves `1 + spec` rows per decoding sequence plus an eighth
+  of the budget per *waiting* request or prefill, and the source refuses to halve for "decode rows
+  alone", so a shape can run `auto` and still lose every chunk step. Prove engagement from
+  `engine_prefill_chunks_capped_total` against the chunk-step count. The floor is the prefill
+  stager's smallest pass — the largest arena level that lends, plus one, named on the startup line
+  `prefill staging: … a step of more than N tokens copies the pooled experts of …` — and under it
+  every routed layer reads its pooled experts synchronously: the vendor prices the whole job (four
+  decoders plus a long prompt) at **29.5 s with a 2048 chunk and 31.9 s at 512**, so shrinking the
+  chunk blindly buys latency in both directions.
+- `--prefill-span N` — needs `--max-num-batched-tokens` of N intervals. A *lone* prefill then
+  carries N intervals a step (on an expert-tiered box only from 8 intervals, where the vendor's own
+  measurement says a span starts to win), while **every other step is planned at the shared
+  budget** — a lending arena level that also keeps the stager's ring, the one combination the chunk
+  knob cannot express. Priced by the vendor at 320 MiB a card of expert residency, ~3 % off the KV
+  pool, and TTFT-neutral on one of his two 2×R9700 boxes: measure your own prompt lengths first.
+- `--max-num-batched-tokens` alone — the blunt rung, and the only one older pins have. It raises the
+  arena the expert slab loses, and on this payload its resonance is violent (MNBT 2560 collapses
+  decode — [[frank-archon]]).
+
+Two traps. **The arena/slab coupling makes a shared step expensive twice:** the full-plan arena is
+reclaimed from the expert slab *synchronously before the step*, and the loan regrows only after a
+quiet interval, so every step of a prefill run — the decode-only ones included — runs on the smaller
+slab. And **re-check `prefix_hit_rate` / `prefix_evictions` after any chunk or span change**: the
+arena, the staging ring and the KV pool are the same memory, and the failure looks like turn two
+taking exactly as long as turn one.
+
+Availability is a version question, not a config question: `--busy-prefill-chunk`,
+`--prefill-interleave` and `--prefill-span` are absent from older pins — prove it on the running
+container (`podman exec <c> <binary> --help | grep -iE "prefill|chunk"`) or from `/diagnostics`'s
+`configuration` block, never from a vendored tree, and check a source clone's depth before dating a
+flag from `git log -S` (a `--depth 1` clone reports its own tip for every search).
+
+Run on: [[frank-archon]] — owner of the live census, the measured step pair, and the arms.

+  `kv_cap` is `KVManager::ceiling()` = `state + Σ_paged max_seqs × ceil(max_ctx / block) × bytes`
+  (`core/mem/kv.cpp:266`), so `--max-num-seqs` and `--max-model-len` set the cache's **demand**, never
+  its funding. The funding is `elastic − expert_floor`, and the floor is
+  `min(plane + spare, plane + spare + 2·unit_max − host_room)` (`core/place/planner.cpp:100-104`, with
+  `host_room = host_pool − file_stage_reserve` at `core/engine_bringup.cpp:1418-1422`). **That is the

-  So `--max-num-seqs` is a **demand signal** for the resolver and an admission cap for the scheduler —
-  never a KV allocation — and no slot count fully funds the worst case. Growing host RAM by less than a
-  slab step (640 MiB) moved nothing: the expert plane's claim decides what is left for KV, so cache is
-  grown through slots × window or the dtype, and experts are grown by not leaving elastic pool idle.
-  `--host-pool-mib` is still load-bearing the other way — it is where the expert rows the cards cannot
-  hold get pinned, and under-sizing it has always been a boot failure (36,864 refused a boot in the fp8
-  era). The two-slot boot's own behavioural check: three concurrent conversations all answer `200` —
-  the third **queues** (`queue_cap: 16`), it is not refused; the 400 class is a single request over
-  `--max-model-len`, or three concurrent full-height conversations against a 1.8-session cache.

+  else moves: decode-*only* steps stay 14-18 ms in every bucket (14.1 ms in a prefill-free minute,
+  17.9 ms in the deep one) and the relationship is lag-0 only (r = −0.74 at lag 0, |r| ≤ 0.19 from
+  30 s on, decode back at baseline by 5 min) — residency is not the mechanism either. The second
+  victim is the **arriving** request: through a high-prefill window TTFT p90 goes 2.4 → **18.0 s**
+  and 15.5 % of requests wait over 10 s for their first token, with `http_queue_depth` at 2-3, while
+  median TTFT (~1.9 s) and per-token latency barely move. Preemption is real but burst-shaped: 264
+  `vllm:num_preemptions_total` in the boot, 108 of them inside 105 s of a 6.5k-tok/s prefill. The
+  chunk is `min(remaining, checkpoint interval, MNBT, busy_cap)`; the first three read 2048 here,
+  and `busy_cap` is the fourth law.
+- **`auto` is a prefill-speed dial, not a decoder-protection dial.** `Scheduler::busy_cap` reserves
+  `1 + spec` rows per decoding sequence behind the chunk (3 tokens at MTP 2) plus one eighth of the
+  budget per *waiting request or waiting prefill*, and the code refuses to do more for decoders:
+  "not for decode rows alone: their reserve is a few tokens, so the chunk ends a quantum short and
+  the next step finishes the interval… Halving would hold a long prompt to half-interval chunks while
+  anything decodes behind it, which costs more" (`core/sched/scheduler.cpp:874-878`, 1.8.1). Live
+  proof: `prefill_chunks_capped` 5,018 against 62,386 chunk steps — 8 %, and those are the minutes
+  with a waiter, not the minutes with a decoder. An explicit `N` is the only value that applies
+  "whenever the chunk shares the step".
+- **At MNBT 2048 no chunk value keeps both the arena loan and the staged copies.** The arena is a
+  ladder of levels (256 and 1024 rows here) and a step's rows are its **whole** token count —
+  `max(n_tok, n_seq × (1 + spec))`, `core/engine.cpp:1142` — so a 1024-token chunk with two decode
+  rows is a 1030-row step: it falls back to the full plan, which "lends nothing", and it arms the
+  prefill stager. The stager's floor is the largest lending level plus one, 1025 rows here — named on
+  the boot line `prefill staging: … a step of more than 1024 tokens copies the pooled experts of 48
+  routed layers onto the card up to 3 layers ahead` — and below it "every routed layer reads its
+  pooled experts synchronously and the prefill slows far more than sharing saves" (GUIDE §4.5). The
+  vendor's own number for naive shrinking, on this architecture: four decoders with a long prompt
+  beside them finished in **29.5 s at a 2048 chunk and 31.9 s at 512**.
+- **A big step takes the arena from the expert slab and keeps it for the whole prefill.** The arena
+  lends 987.77 MiB (steps ≤ 256 rows) or 670.26 MiB (≤ 1024) to the slab; a full-plan step reclaims
+  it **synchronously before the step** — units revert to their host copies (an address change, not a
+  copy) and both read streams drain — and `arena_tick` regrows the loan only **2 s after the last big
+  step** (`core/engine.cpp:1129-1202`), so every step of the prefill run, decode-only included, runs
+  with a slab ~780 expert units smaller over a link also carrying the staged copies. `/diagnostics`
+  says the binding constraint in one line: "a prefill step streams every routed layer's pooled
+  experts onto the card, so its speed is bounded by the link; decode reads the ones it routes to".
+  Measured size of the whole effect: the ~10 % above. Real, small, not worth chasing.
+- **`--prefill-interleave` is the dial that buys decode its cadence; armed at 1 on 2026-10-20.**
+  N decode-only steps follow any chunk step taken beside decoders; held steps admit nothing, so it
+  costs the prefilling prompt its TTFT and an arriving request its first step. Rate arithmetic at the
+  two measured step times and 0.657 acceptance (≈2.3 tokens a step): N=0 → ~14 t/s, **N=1 (armed) →
+  ~23**, N=2 → ~33, N=4 → ~48, N=8 → ~69, with the prefill slowed by (166 + 15.5N)/166. **Arithmetic, not
+  measurement** — the arm is chosen by the §9 bucket pair plus `steps_held`, and `auto` is not a
+  substitute for it.
+- **`--prefill-span` is the shape that keeps the loan, and it is priced.** It needs MNBT = N
+  intervals, so `--prefill-span 2 --max-num-batched-tokens 4096`: a *lone* prefill carries 2
+  intervals a step (and on an expert-tiered box only from 8 intervals / 16k tokens, where the span
+  starts to win), while **every other step is planned at the shared budget of 2048** — which is a
+  lending level *and* keeps the stager's ring, the one combination `--busy-prefill-chunk` cannot
+  express. Costs per GUIDE §4.5: 320 MiB a card of expert residency, ~3 % off the KV pool (§4.3's
+  cliff is sharp), a decode step uploads twice the per-step arrays at 4096, and checkpoints inside a
+  span are not written, so a partially-shared prompt resumes one interval earlier. On the vendor's
+  second box (2×R9700, w4nl64, TP2) it was TTFT-neutral — 2.61 vs 2.56 s at 18k, 10.72 vs 10.55 at
+  75k — hence their own rule: measure your own prompts at two ranks before turning it on. MNBT 4096
+  does not boot at 3 slots; this shape is 2.
+- **Most of this endpoint's prefill work is replay of tokens the prefix cache already had.** Over
+  the same window `prefill_tokens_total` 65.2 M against `prefix_hit_cut_tokens_total` 24.9 M = **38 %
+  replayed**, and it is not an eviction: a hit on a hybrid model reuses only as far as the last
+  **linear-state** checkpoint (`reuse = min(h.n_attn_tokens, h.n_linear_tokens)`,
+  `core/sched/scheduler.cpp:953-978`), and the retention default keeps a **geometric ladder** - about
+  `log2(depth/interval) + 2` snapshots - so a turn that diverges `d` behind the tip can resume as
+  deep as `tip − 3d`. The live ladder for a 200k session at interval 2048 is 2048 · 131072 · 163840
+  · … · 198656: diverge at 120k and 21.7k tokens replay, diverge at 50k and 48k. Every
+  `prefix_hit_cuts_total` carries `reason="no_snapshot"` (the other two reasons stay dead), so the
+  cause object agrees and `hit_cut_tokens` is the cost. `--checkpoint-policy` admits exactly
+  **`geometric-backoff` | `tip-only` | `keep-all`** and refuses anything else at boot. It governs
+  retention only - the writes happen at every interval whatever the policy says (only `--prefill-span`
+  skips them) - so `keep-all` buys a replay bounded by one interval at any depth for **pinned host RAM
+  alone**: 97 snapshots a 200k session, `--checkpoint-slots auto` asking 196 × 111.98 MiB = 21.4 GiB
+  against a store budget of an eighth of host RAM (31.5 GiB here, so `share` admits it) with `room` -
+  the pinning room left beside the expert pool at boot - as the hard bound the ledger line names.
+  Retention also spares a snapshot a later turn resumed from (`core/mem/prefix.cpp:709-723`), so a
+  chain that keeps resuming at one deep point stops paying for it. Shortening
+  `--checkpoint-interval` does **not** buy the deep case: the coarsest ladder scale is the largest
+  `interval × 2^k` under the depth, so the deepest gap stays ≈ half the prompt (129,024 tokens at
+  interval 2048 against 130,816 at 256) while every cut multiplies the snapshot writes.
+- **Slots cost KV, host RAM, rows, and pin — never speed.** `--max-num-seqs` carries no radiance
+  constraint: it adds ≈110 MiB of recurrent state per slot, 10 × 111.98 MiB of pinned checkpoint-store
+  RAM per slot (`--checkpoint-slots auto`), and declares the fused TP all-reduce over
+  `seqs × (1 + spec)` rows — `wht6` is bit-exact up to 25 rows, and the live shape is 4 × 3 = **12**, so

+  the cache's *demand* (`ceiling = slots × window`), which the resolver funds from `elastic −
