Index maps that survive moves

When drawers, offices, or safes change, the map must change first — then the envelopes.

Stack of open books on a table

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.
