-## Why root (the load-bearing decision)
+## Why Alloy and not Promtail
 
-A rootless Alloy delivered **zero** lines, silently and with a green health
+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`).
-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 — one `loki.source.journal`
+`shared/alloy/config.alloy` is the source of truth:

-in the journal.
+- 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`).

-## The UI stays on loopback
+## The UI port is published on purpose
 
-Alloy 1.x refuses to configure the `ui` service from a config block, so the UI
+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`).

-card and the deploy health gate both dial `http://127.0.0.1:12345/-/healthy`.
+
+**Root cause, proven: a rootless container cannot read the host journal.** The
+journal files are `root:systemd-journal 0640` (with `group:adm`, `other::---`).
+`/var/log` is bind-mounted so the files are *visible*, but a rootless container
+spawns with no supplementary groups, so it is denied. Proven directly:
+`podman run --rm -v /var/log/journal:/var/log/journal:ro busybox cat
+/var/log/journal/*/system.journal` → `DENIED`. `loki.source.journal` opens via
+`sd_journal_open`, so it silently sees an empty view — no error logged, counter
+frozen at `loki_source_journal_target_lines_total 0` (`system.journal` and
+`user-1000.journal` are both present and non-trivial, 2026-10-20).
+
+**Second, independent gap:** the rootless Quadlet containers log to the *user*
+journal (`user-1000.journal`), and `loki.source.journal` reads the *system*
+journal only — a fixed system read would still miss them. Container stdout is
+not in a `ctr.log` here either: the file globs point at root storage
+(`/var/lib/containers/storage/.../ctr.log`, `/var/log/containers/*.log`) that
+rootless does not use, refused at start with `stat …: permission denied` / `no
+such file or directory`, `loki_source_file_files_active_total 0`.
+
+Downstream: Loki holds zero streams (`GET /loki/api/v1/labels` → no `data`) —
+see [[Loki]].
+
+**Closing it is a permission/architecture decision, not a config edit.** The
+unit, config and push endpoint are correct as written; rootless Podman simply
+cannot grant the journal group. The viable shapes: run Alloy as a *system*
+service (root, in `adm`/`systemd-journal`) instead of a rootless Quadlet; grant
+the container's mapped uid journal read via a tmpfiles/ACL rule; or have
+journald forward to a path the container can read. Each trades rootless posture
+for reach — decide deliberately. Re-check `loki_source_journal_target_lines_total`
+and the Loki label query to confirm a fix, never `/healthy`: health is exactly
+what hides this failure.
 
 ## Gotchas
 
-- **No `/etc/machine-id` mount ⇒ silent zero.** The health check still passes.
+- The journald socket mount is required for journal scraping.
-  This is the failure mode that hid the broken pipeline; check
+- 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.
-  `loki_source_journal_target_lines_total` and the Loki label query, never
+- One Alloy per host; do not run a single instance that tries to reach both hosts' logs.
-  `/healthy`.
+- The unit `Wants=`/`After=` `loki.service`: without a reachable Loki the write client fails and the pipeline backs up.
-- **`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.
