Security evidence
Keep the record, including what could not be confirmed.
Ordered records that someone outside the team can read. A research area, not a product.
What we study
What a record has to hold.
What belongs in one observation?
Approved identity, reported identity, policy result and arrival time.
How is missing evidence recorded?
As unavailable, with a reason. Never as the last known state.
Can a reader tell a self-report from proof?
Only if every record carries its scope.
How does a record stay in order?
Discrepancies, gaps and recovery in one sequence, nothing hidden.
What exists today
Recorded observations, in the experiment.
- Working in the experimentDeployment evidence: four observations recorded in order, including evidence unavailable.
- Working in the experimentEach keeps the approved identity, the worker's reported runtime identity and the policy result.
- Working in the experimentRecovery verification: after one recorded explicit reload, the reported identity was compared again.
- Working in the experimentThe app refuses to import pending, missing evidence or wrong runtime observations as matched.
- ProposedRecovery failure tests, specified but not run, and an investigation workflow.
- Not claimedIndependent attestation. Every record is a worker self-report.
Open questions
What is still open.
Edited records
An edited, self-consistent trace still validates today.
Evidence freshness
Heartbeats that show a report is current, not stale. Not built.
Expected silence
Telling a planned outage from a fault.
Reviewer effort
Time for an outsider to reach a conclusion. Not measured.
