Signed snapshots
Daily merkle roots, published publicly, so a historical record can be proven unaltered.
What is published
Each day we publish a merkle root over the tape and the multiplier series, cheaply anchored onchain. Any customer can prove that a record they hold was included in that day's data and has not been altered since.
For a regulated buyer producing NAV or client reporting, this is the difference between a vendor they can use and one their auditor rejects.

Correctness note
A snapshot proves inclusion and integrity, not accuracy. It shows the data has not changed since publication; the invariant suite is what argues it was right in the first place. The two are complementary and neither substitutes for the other.
