Firmware stamps that stick
Firmware updates arrive with urgency that is rarely yours. Vendors ship patches; your calendar ships dinner plans. A Hardware Wallet Usage Ledger needs a stamp small enough to complete before the progress bar finishes.
We ask learners to capture four fields only: previous version, new version, source of the update prompt, and which human initiated it. Optional fifth field: whether a second device was updated the same night (answer should usually be no).
Why stamps beat memory
People remember that they “updated last month.” They rarely remember which of two similar devices moved first. When a companion app later complains about a mismatch, the stamp is the difference between a five-minute check and a weekend of doubt.
Keep secrets out
The stamp never includes seed material, PINs, or screenshots of recovery flows. If your note needs a password to be useful, the note is in the wrong notebook.
