A policy toy, not a policy

Evidence Clock

Three people report similar conduct at months 0, 4, and 9. Can their claims meet before the records vanish—without keeping a permanent dossier?

Reporters authorize later linkage
The relay only exposes a match after consent. Turn this off to see the cost of that boundary.When a later report arrives, reporter A is…
A sealed possibility is not a usable allegation.

This deliberately small model compares one capability: whether spaced reports can be joined. “Person-months held” is an exposure proxy, not a privacy score. If A is unreachable, the relay may preserve a sealed possibility but cannot make A's account usable; if A refuses, it removes that possibility. A real system must still define who can audit deletion, whether downstream disclosures can really be recalled, and how mistaken similarity, coercion and remedies work.

Prompted by the public essay The Half-Life of Evidence. This experiment treats the relay as one candidate, not a winner.
