6d224861 came from a --no-checkout worktree whose empty index made the
commit drop every file except two. This restores 05b50d2b's full tree and
correctly adds stacks/stem95su/gdrive-sync.tf + the service-catalog stem95su
entry. Forward-only (parent=6d224861, no force-push); [ci skip] since the
live infra was never applied from the broken commit.

CronJob stem95su-gdrive-sync (*/10) mounts the content PVC RW and
rclone-syncs the read-only Drive folder "claude" (stem claude/files) onto
it (rclone/rclone:1.74.3, scope=drive.readonly, empty-source guard +
--max-delete 25). ESO ExternalSecret stem95su-rclone <- Vault
secret/stem95su. Requires the GCP OAuth app published to Production or the
refresh token expires ~weekly.
Lands the gdrive-sync stack on master (it had landed on a feature branch
by accident on the shared devvm checkout).

The dashboard-it Server → Fans view is now minimal: fan speed (% + RPM), an
Override % slider, and a Lock toggle. Lock now means "freeze the current speed,
algorithm off" — a new automation (r730_fan_lock_freeze_current_speed_resume_algo)
snapshots the live target % into Override and sets mode=manual on lock-ON, and
mode=auto on lock-OFF. The host daemon is unchanged (the toggle just drives the
mode it already reads). cool/quiet stay reachable via the entity but are off the
simplified view; the 60-min auto-revert is kept as a dormant safety net. Verified
live: lock ON → mode=manual + Override captured the live 60%; lock OFF → auto.

A manual/cool/quiet override in HA auto-reverts to `auto` after 60 min. Add a
Fan Lock (`input_boolean.r730_fan_lock`) that gates that automation so a
deliberate override persists, with a visible "🔒 FAN CONTROL LOCKED" banner on
the dashboard-it Server view so it isn't forgotten. The automation re-checks the
lock after the hour (locking mid-countdown cancels the revert) and the 83 °C
ceiling still wins. HA-side only (helper + automation + dashboard live on
ha-sofia, auto-git-tracked there); these docs are the infra-repo record.

The iDRAC reports only total DCMI watts + RPM (no per-fan power), so add a
cube-law fan-power estimate: fan_W ~= 0.0205*(RPM/1000)^3, calibrated to the
2026-06-05 sweep (fits within ~3W; ~2W floor -> ~99W full). The daemon reads
live RPM each loop and pushes pve_fan_control_fan_rpm + _fan_watts_est.
Surfaced in HA as sensor.r730_fan_power_est + a "Fan Power (est)" card on the
dashboard-it Server view, next to total power. 46 bash tests green; verified
live (9120rpm -> ~15W est).

Replace the step-band fan curve with a continuous linear ramp — the bands
flapped at edges (e.g. 45<->65%). Web-researched: linear + 2-3C hysteresis
is the homelab standard; PID is overkill for this slow thermal loop.
fan% now interpolates between env-tunable anchors:
COOL 50C/30% -> 83C/100% (~2.1%/C; ~51% at the ~60C equilibrium)
QUIET 68C/20% -> 83C/100% (near-silent until ~70C)
Both reach 100% at the 83C ceiling. Anti-oscillation: asymmetric
hysteresis (fc_decide) + a MIN_STEP (3%) min-change threshold.
41 bash tests green; deployed + verified live (59C -> 49%, smooth).

Document the HA-control feature shipped in 8beca1df: the daemon reads the
ha-sofia r730_fan_mode/manual_pct helpers, the 60-min auto-revert automation,
and the dashboard-it Server-view sensors + control tiles.

Power/temp sweep (2026-06-05) located the cooling-per-watt knee at ~60%:
60->70% buys only -2C for +21W, and 70->100% buys 0C for +54W (the CPU
floors ~59C at cluster load, so more airflow does nothing). Re-tune the
COOL curve to cap its normal band at 60% (~303W, ~61C); 80/100% become a
high-load safety ramp (>=73/79C) before the 83C ceiling. QUIET unchanged
(already at the 281W / 4800rpm floor). Saves up to ~75W (~650 kWh/yr) vs
full-tilt for the last ~2C. Tests + design doc updated; verified live
(63C, 60%, ~267W).

The iDRAC stock curve runs the CPU at ~72°C on the 7080 RPM floor even
under load (optimises for quiet, not cool). Add a bash daemon + systemd
unit that drives the chassis fans from CPU temp on two curves, picked by
garage occupancy (the server is in the garage): COOL when empty
(measured ~58-65°C under load), QUIET near the silent floor when the
ha-sofia garage door shows someone is there (open, or <15min since last
activity).
Manual fan mode is backstopped: bash EXIT trap + systemd ExecStopPost
hand fans back to Dell auto on stop/crash; CPU>=83°C or repeated IPMI
failures do the same. Pushgateway metrics (job=fan_control). 36 unit
tests cover the pure curve/hysteresis/presence/parse logic; DRY_RUN +
RUN_ONCE for integration checks. Deployed and verified on 192.168.1.127
(CPU 70->58°C in cool mode, hysteresis stepping confirmed).
