Earlier signal
Find correctness failures before they become incidents or expensive investigations.
Software assuranceSentry
Know what your tests
cannot tell you.
Sentry reads a codebase, generalises its expected behaviour, and searches for cases that violate it – before release.

What changes
Testing becomes a claim.
Stronger coverage
Replace a pile of examples with the behaviour they were trying to establish.
Release confidence
Make critical guarantees part of the decision to ship, not a document beside it.
When a software claim demands formal certainty, Sentry calls the same proof engine available directly through Hydra.
