Evidence packs
LiveFreeze a risk report and hash it, so you can prove later what the product said at the time.
- ✓Frozen risk-report snapshot with a content hash
- ✓Verification that re-hashes and compares
- ✓No edit and no delete — by design, not by omission
- ✓Repeat freezes allowed, so a later pack can prove an earlier one is unchanged
What it is.
An evidence pack is a frozen copy of a contract's risk report at one moment, with a hash over its contents. Later, a verify call re-hashes the stored payload and tells you whether it still matches — so a pack is a record you can stand behind rather than a screenshot.
There is no way to edit or delete a pack, and that is the feature rather than an omission: a record you can change after the fact answers nothing. A corrected analysis is a new pack, and both remain. Freezing the same report twice is allowed on purpose — the second pack proves the first was not altered in between.
Three steps.
End to end.
Create a pack from a contract's current risk report.
Packs are listed newest first. Nothing overwrites an earlier one.
A verify call re-hashes the stored payload and reports whether it still matches.
What you get.
- ✓Frozen risk-report snapshot with a content hash
- ✓Verification that re-hashes and compares
- ✓No edit and no delete — by design, not by omission
- ✓Repeat freezes allowed, so a later pack can prove an earlier one is unchanged
- ✓Sits alongside the append-only audit log, which is enforced by database triggers
Quick answers.
Because a record you can delete is not evidence. If an analysis was wrong, freeze the corrected one — both will be there, which is more honest than one that has been tidied.
No. It proves what the analysis said and that it has not been altered since. Those are different claims and we are not going to blur them.
