Essays on rules that survive being written. A buddy check on the discipline, performed now, in writing, while the gear is still dry and the cost of catching a leak is two hours.
A real account through one melt-up and one rollover, April to June. The same portfolio, two timeframes, and two true numbers that disagree completely. The evidence the essays keep theorising about, this time with the gauge readings attached.
A ninety-second ritual exists for the day nothing usually goes wrong. The same is true of a written rule. The check is the entry condition for everything else.
