how do you turn a field fix into a bkm

This is THE GPS core task. Your steps: 1) CAPTURE the fix while it's fresh — symptom, root cause, and the exact steps that resolved it (and what did NOT work). 2) VALIDATE it — did it actually hold (Lesson 38), and does it generalize to similar cases? 3) WRITE it as a BKM — clear, step-by-step, with the why and the warning signs, written for a field engineer with less context. 4) REVIEW it — get a peer/expert to check it for accuracy and gaps. 5) SHARE/MAINTAIN it — put it where the field can find it, note the version, and update it as you learn more. The one-line frame: 'I turn a fix into a BKM by capturing it while it's fresh, validating it holds, writing it so someone less experienced can follow it, getting it reviewed, and keeping it current.' It proves you know a BKM isn't just 'writing it down' — it's a validated, reviewed, maintained asset (Lesson 2).
