GUIDE 02 / FLEET ROLLOUT
# Roll out across a fleet
From a pilot cohort to thousands of machines: baseline first, observable waves after, stop gates between them and a named owner for the rollback.

## Stage 01 · Baseline
- Record what you haveExport the current hashrate, power draw, temperature bands and error rates per worker. This is what you will compare against - without it every later number is an opinion
- Fix the site limitsAmbient temperature, breaker headroom, generator ceiling if you have one. These decide which profile you are allowed to use
- Name the rollback ownerOne person, by name, who can decide to stop and revert without a meeting

## Stage 02 · Pilot cohort
- Pick 1-5 machinesSame model, same board, same rack position type as the bulk of the fleet
- Install through the toolkitGroup scan, select the cohort, install firmware, confirm
- Run 24-48 hours untouchedLonger if you have day/night ambient swings
- Compare against the baselineAccepted hashrate, J/TH, chip temperature spread, rejected shares, fan duty. Any of these going the wrong way is a stop

## Stage 03 · Observable waves
- Wave one: 10-20% of the fleetOnly what survived the pilot, same settings, same file
- Hold the gateWatch a full day. Fleet aggregate and worst-worker both have to stay inside the band you accepted
- Scale the waveDouble it while the numbers hold. Stop and revert the moment they do not
- Keep one control layerCentral monitoring, one decision gate per wave, one owner. Not a spreadsheet per shift
- Chip temperature above the band you set for the site
- Rejected shares climbing above the baseline
- Any machine that needs a manual touch to come back
- Any wave you cannot revert within one shift
