The opt-in encrypted cache crash-looped on launch (UnsatisfiedLinkError:
No implementation found for SQLiteConnection.nativeOpen) on any cold start
after encryption was enabled — reported after an app upgrade.
System.loadLibrary("sqlcipher") was only invoked as a side effect of an
actual plaintext<->encrypted conversion (DatabaseEncryption.migrate) or the
one-time #111 account migration. On a steady-state start the cache is
already encrypted and the account migration is already done, so both no-op
and nothing loads the native library before Room opens the keyed database
via SupportOpenHelperFactory -> nativeOpen. The previous process survived
only because an earlier conversion had loaded the .so in-memory; the next
cold start (e.g. an upgrade) crashes.
Load the library explicitly in DatabaseProvisioner whenever it commits to an
encrypted open (idempotent; no-ops when already loaded). Add regression
assertions: the encrypted path must load it, the plaintext path must not.
Verified on a Pixel 10 Pro XL — an in-place update preserving the already-
encrypted cache now launches to the mailbox instead of crash-looping.
