quantmodel — Rehearse participant deletion and backup-expiry verification

Objective

Rehearse participant deletion and backup-expiry verification.

Notes: Built and synthetically verified a fail-closed redacted operator command for export, row deletion, session revocation, identity deletion, zero-row/old-token assertions, and seven-day backup inventory expiry. Live proof remains NO-GO because this runner had no provider secrets or elapsed inventory; see participant-deletion-t298.md.

Approach

Reuses existing report research/findings/participant-deletion-t298.md — tables/metrics preserved verbatim via source_report pointer. Body below summarizes grounded evidence from that report and adjacent artifacts.
