- isExpired (#10): NIP-40 says an event is expired *once* `expiration`
is reached, and the SQL trigger uses `<= unixepoch()`. The Kotlin
pre-check used `<` (strict) so an event with `expiration == now`
passed the Kotlin check then failed in the trigger. Both layers now
use `<=`. Also applies to `isExpirationBefore` for consistency.
- transaction extension (#7): if the body throws *and* ROLLBACK also
throws, we now attach the rollback failure as a suppressed exception
instead of letting it mask the original cause. COMMIT is moved outside
the catch so a commit failure doesn't trigger a second ROLLBACK on
already-finalized transaction state.
- SeedModule.hasher (#8): the cache field is now a `kotlin.concurrent.
atomics.AtomicReference` (matches the pattern used in BleChunkAssembler
and BasicRelayClient) so the hasher publication is visible across
threads. The race itself is benign — the seed is stable, so two
concurrent computations produce identical hashers — but the prior
plain `var` had no visibility guarantee.
- delete(Filter()) (#12): documents the intentional asymmetry — `query`
on an empty filter returns everything, but `delete` on an empty
filter is a no-op (safe-by-default). New test pins the contract.
Tests:
- testInsertingEventExpiringExactlyNow: events with `expiration == now`
are rejected by both Kotlin and the trigger.
- testTransactionRollsBackOnException: a user transaction whose body
throws leaves the DB unchanged and still accepts new writes.
- testDeleteWithEmptyFilterIsSafe: empty-filter delete is a no-op.
