Empty header range during checkpoint anchoring, send-all limits, SyncCache roundtrip, corrupted config, derivation edge cases, spendability boundaries, unit formatting, loader errors, in-flight cap, disposal under load and wallet-lock contention. Also raises the synchronizer partial-result timeouts so they hold under load.
