 # Bundle Change Log
 
+## 2026-09-21 — node-dankclaw Prometheus target fixed (netavark host-bind quirk)
+
+- **The gap.** A deep audit found the `node-dankclaw` scrape target red while
+  its container reported healthy. node-exporter runs `Network=host`, so its
+  `192.168.0.143:9100` bind is a host bind, not a published port — and this
+  Prometheus is a bridge container (`Network=dankclaw_default`) that, on this
+  netavark host, can only reach the host's LAN IP at a PUBLISHED port. The
+  target was unreachable by construction, not the exporter down. This was a
+  fourth down job the 2026-09-16 "three jobs read down" audit did not list.
+- **The fix.** Scrape `host.containers.internal:9100` instead — netavark
+  delivers that address to the host's LAN IP, where node-exporter listens.
+  The same rule `frank-large` and `frank-small` already use (documented in the
+  LLM comment block of `shared/prometheus/prometheus.yml`). `node-dankserver`
+  is a different machine and keeps its LAN address. Verified live: the
+  workaround returns real metrics from inside the container, and after deploy
+  `up{job="node-dankclaw"}` is 1 — the down set is back to exactly the three
+  structural jobs (comfyui, services, gitea).
+- **Files.** `shared/prometheus/prometheus.yml` (target + comment),
+  `serverAppConfigs-docs/Infrastructure/Prometheus.md` (Targets table), and the
+  cross-file contract test `tests/observability_quadlet.bats` (now asserts the
+  exporter binds the LAN address AND the local job scrapes via the gateway,
+  instead of asserting scrape-target == LAN address, which the quirk breaks).
+
 ## 2026-09-20 — DFlash2 vs MTP A/B on the FP8 checkpoint: DFlash2 wins on decode
 
 - **The test.** The FP8 checkpoint carries its own single-layer MTP head, so
