* Make sure that storage tries are not pruned (by default) on the new Ledger API why: Pruning might kill some unwanted entries from storage tries ending up with an unstable database leading to crashes. * Implement `CoreDb` and `LedgerRef` API tracing details: + Locally enabled at compile time via constants `ProvideCoreDbLegacyAPI` and `EnableApiTracking` in either `base.nim` source + If enabled it can be selectively turned on/off via public switches in the `CoreDb` descriptor. * Allow suppressing opportunistic `ifNecessaryGetXxx()` functions why: Better troubleshooting when the system crashes (assertions will then most probably happen outside an `async` function.)
