feat(grafana): graph frank-archon in llm-fleet (radiance vllm:*/radiance:* + a new endpoint section)

frank-archon (radiance, Dankserver) emits vllm:* + radiance:* (job=frank-archon).
llm-fleet.json queried only llamacpp:* and its endpoint picker selected via
label_values(llamacpp:.*), so archon - despite being scraped and alert-on
(vllm-fleet group) - had zero panels. The dashboard description also still
claimed archon was llama.cpp, which is stale.

- Fix the description: two namespaces; the $job picker is the llama.cpp pair
  (dragoon/zealot); archon is radiance and gets its own section.
- Add a frank-archon row + 8 panels: vllm:* throughput, request outcomes by
  finish reason, queue/preemption, TTFT p50/p95, and the radiance natives vllm
  omits - decode/prefill t/s, MTP draft acceptance, engine-step timing, prefix
  hit. All 14 queries verified live against Prometheus (non-empty).

Dashboards-only; the next grafana deploy provisions it.

+# this unit runs on the host network and pushes to 127.0.0.1:3100. The side
+# effect: the UI must bind loopback too, so Exec sets the listen-addr to
+# 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
+# unauthenticated UI stays loopback-only — nothing off-host reaches it).
 #
-# NETWORK. It joins dankclaw_default so its config's loki.write endpoint
-# resolves the container name loki:3100.
+# THE /etc/machine-id MOUNT IS LOAD-BEARING. sd_journal locates the journal
+# directory by the local machine id; without it the container opens nothing and

+# This mount is the entire reason the pipeline carries data. Never remove it.
 #
-# 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"
-# continuously and there was nothing for a deploy to wait on. The command
-# 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.

+# repo-managed) silently broke that login, and BOTH had previously been
+# mis-recorded here as a single "the property-mapping evaluator is broken, so
+# userinfo returns only `sub`" myth. They are neither, and the evaluator is fine:
+#
+#   1. provider.authorization_flow was NULL. The authorize view builds a flow
+#      planner from it and crashes with
+#      `AttributeError: 'NoneType' object has no attribute 'slug'` — an HTTP 500
+#      "Server Error — Powered by authentik", before any claim is touched.
+#      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
+#      keyed under the mapping's NAME ("grafana-email-scope"), so no `email`
+#      claim is ever emitted. Grafana, finding no email, falls back to
+#      GET <api_url>/emails, authentik 404s that path, and the login dies with
+#      "Login failed: InternalError". Fix: return
+#      {"email": user.email, "email_verified": True} — the shape the stock
+#      OpenID 'email' mapping uses. The dict-valued `grafana-profile-scope`
+#      mapping has always worked, which is the proof the evaluator is fine.
+#
+# This is authentik DB state. It is NOT in any deployable file: a blueprint

It is wired to forward container and journal logs to Loki, and every unit in the path is healthy — but as of 2026-10-18 it is delivering **zero** log lines. See "Delivery state" below.

-| Unit | `dankclaw/observability/quadlet/alloy.container` → `alloy.service` |
-| Config | `shared/alloy/config.alloy`, installed to `/opt/alloy/config/config.alloy` on every deploy (`scripts/deploy-remote.sh:281-284`) |
-| Inputs | host journald socket, podman container logs, `/var/log` |
-| Output | `http://loki:3100/loki/api/v1/push` (`shared/alloy/config.alloy:13-17`) |
-| Successor to | Promtail (EOL 2026-03-02, https://grafana.com/docs/loki/latest/send-data/promtail/) |
-| Boot persistence | `Restart=always`/`RestartSec=10` + `WantedBy=default.target` (`dankclaw/observability/quadlet/alloy.container:58-63`); installed at `~/.config/containers/systemd/alloy.container`, reporting `generated` + `active` (`systemctl --user is-enabled|is-active alloy` 2026-10-18) |
-| Delivery | **Configured and healthy, currently delivering zero data** — see "Delivery state" |
+| Image | `localhost/franksdank/alloy:latest` — built rootless, then mirrored into the root image store by the deployer (a root build fails on DNS in this host's build container) |
+| Unit | `dankclaw/observability/quadlet/alloy.container` → system `alloy.service`, installed at `/etc/containers/systemd/` (root manager) |
+| Config | `shared/alloy/config.alloy` → `/opt/alloy/config/config.alloy` on every deploy |
+| Network | `host` — required so it can reach Loki's `127.0.0.1:3100` publish |
+| UI | `--server.http.listen-addr=127.0.0.1:12345` (loopback; nothing off-host reaches it) |
+| Inputs | host journal: `system.journal` + `user-*.journal` (root reads both) |
+| Output | `http://127.0.0.1:3100/loki/api/v1/push` |
+| Boot persistence | `Restart=always`/`RestartSec=10` + `WantedBy=multi-user.target`; boot persistence is the `[Install]` section (generated system units cannot be `enable`d here) |
+| Successor to | Promtail (EOL 2026-03-02) |
+| Deploy status | root cutover built and tested in-repo (2026-10-20); the **live** instance is still the old rootless unit until `./scripts/deploy.sh dankclaw --service alloy` runs |
 
-## 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.

+  mis-attributed to a broken evaluator; the crash is the missing flow. Fix: set
+  `authorization_flow = default-provider-authorization-implicit-consent` (the
+  flow every other provider in this instance already uses).
+- **A scope mapping that returns a non-dict emits no claim.** authentik merges a
+  granted scope mapping's evaluated result into the token **as a mapping**: a
+  dict contributes its keys as claims; a bare string is keyed under the
+  mapping's NAME, so nothing usable appears. `grafana-email-scope` returned the
+  bare string `user.email`, so no `email` claim landed — the evaluator was
