f3 is now running node_exporter and is included in Prometheus
scraping alongside f0/f1/f2. Updated the skill reference to
reflect the new scrape config (192.168.2.133:9100) and include
f3 in the host list.

Tag names in the ask CLI do not support hyphens (-). Added a clear
note in both the rules section and the Conventions section of
1-create-task.md so agents use camelCase or concatenated words instead.

f0 sits at the bottom of the rack with a fan directly underneath,
so it consistently runs 10-15°C cooler than f1/f2 at the same load.
f1/f2 are higher up in warmer rising air with no dedicated airflow.
Do not use f0 as a baseline when comparing temps across hosts.

Replace conservative guesses with actual data from Beelink S12 Pro
reviews and Intel N100 specs (TJmax 105°C, hardware throttle ~100°C).
Add a table with scenario/expected/action rows covering idle through
thermal throttle, plus real-world observations from 2026-05-17 across
all four f-hosts. Adjust remediation steps to match the revised
thresholds (investigate >80°C at moderate load; stop I/O at >90°C).

storage.md (942), k3s-setup.md (342), observability.md (273) split into
per-topic sub-files under references/<topic>/ with short index files at
the original paths.
Drops the SSD TRIM Configuration section added in 8d94f79 and reframes
the Thermal Troubleshooting cascade: the 2026-05-16 f0 incident was
thermal alone, not the multi-cause cascade (autotrim, zrepl interval,
encryption) the previous commit implied. Mitigations applied during
diagnosis are not what fixed it.
Other yesterday additions (zrepl DL-state recovery, CARP-when-ZFS-
suspended, ZFS SUSPENDED runbook, nfs-mount-monitor improvements) are
kept and routed to their respective sub-files.

- observability.md: reflect current state — Grafana/Loki/Tempo disabled
(SQLite-on-NFS unreliable), Alloy running with minimal config only,
Prometheus TSDB wiped and restarted clean (2026-05-16 incident).
Add TSDB recovery runbook. Document .disabled manifest pattern.
- freebsd-setup.md: add coretemp kernel module section — all f-hosts
now have coretemp_load="YES" in /boot/loader.conf for persistent
per-core die temps (hw.acpi.thermal.tz0 is unreliable).
- hardware.md: add f3 IP (192.168.1.133) to LAN table.

Documents the 2026-05-16 f0 cascade failure (thermal throttling + autotrim=off
+ aggressive zrepl interval → stuck TRIM, multi-second txg syncs, D-state rsync).
Covers symptoms, per-core temp checks via coretemp vs unreliable hw.acpi.thermal.tz0,
Beelink S12 Pro thermal specifics, and step-by-step remediation.

Switch r0/r1/r2 NFS client mount options from soft,timeo=10,retrans=2,intr
to hard,timeo=600,retrans=3. Removes the soft mount that was causing EIO on
transient stunnel/CARP hiccups; hard mounts retry indefinitely, which is
safer for DB-like workloads (immich, miniflux, audiobookshelf). The intr
option was a no-op since kernel 2.6.25 and is dropped. Navidrome's /data
is now on local-path so it is unaffected by this change.

Update 'Pods stuck' troubleshooting entry: the script is now driven by
a systemd timer (10 s) rather than a cron job (1 min). Add a new
'NFS Auto-Repair: nfs-mount-monitor' section documenting the repo
layout (f3s/r-nodes/nfs-mount-monitor/), the Rex deploy command, what
the script does, and timer configuration.
