Index maps that survive moves
When drawers, offices, or safes change, the map must change first — then the envelopes.
An index map is the spine of the Paper Wallet Record Center. It translates boring location codes into physical places. Moves break maps that were written as prose paragraphs instead of revise-friendly tables.
Write maps as rows
Each row: code, place description, date last verified, initials. Crossing out a row beats scribbling in margins. Retire codes rather than recycling them for a new place too quickly — waiting a full version cycle reduces mix-ups.
Verify after furniture shifts
Any time a container moves more than an arm’s length, schedule a cold find: can someone locate the envelope using only the map? If not, the map is wrong, not the person.
Keep secrets off the map
Indexes describe furniture and rooms. They do not describe contents beyond a neutral category word like “practice” or “recovery-adjacent.” Detail belongs on controlled sheets.
