Which fields a process can see, and which it never fills
A field costs nothing to create and something forever: a layout slot, a permission to maintain, a column in every export, a question in every training. Field usages measures fill per record type, so the unused ones can leave the layout or the org.
For each process row, three amber columns read as a funnel. Allowed is what the profiles that see this record type may read, from field-level security. Visible is what the record type's layouts actually show. Unused is what is visible and filled on fewer than 5% of the records created in the window.

Illustrative — Meridian Hospitality Group. Threshold slider in the panel re-filters locally; the measurement itself is not re-run. Fields on no layout at all are listed by a separate metadata-only action.
What this means on Monday. Open the Unused cell of your busiest record type. Every own custom field under 1% fill with no report dependency is a removal candidate, not a debate.
Why per record type, again
A field that is empty on one process can be the whole point of another. Measured on the object, Charter_Deposit_Waived__c reads as "used"; measured per record type, it is filled on 0.4% of Marina Concierge Bookings and on 61% of Yacht Charters. The master row keeps the intersection (unused on every record type that shows it), so the org-wide verdict is conservative and the per-process verdict is actionable.
What the engine never does
Field usages runs read-only SOQL from the user's own Salesforce CLI session, grouped by record type and bounded by a window. It stores counts, never values. It cannot write, deploy or delete; the removal itself goes through your own release process; Stood Flows never executes a change.
