About this tool and its limits
01 · Problem
The problem
File-sharing links make retention, access, and successful consumption ambiguous long after the transfer should be over.
02 · Change
What changed
Handoff separates encrypted content from a one-time retrieval authority and makes expiry and consumption visible.
03 · Test
What is being tested
Can temporary exchange feel simpler precisely because its lifecycle is narrower and explicit?
04 · Evidence
What can be claimed
- Current scope
- Public transfer flow · one-time retrieval link
- Operating cost
- Negligible marginal cost
- Required evidence
- Drop worker adapter check, live-flow boundary probe, metadata/object lifecycle proof, and single-use consumption evidence.
- Claim limit
- May claim handoff boundary health from no-secret smoke; must not claim one-time consumption proof unless the write/retrieve lifecycle was exercised.
