 "result": {
  "summary": "Removes the `noexcept` specifier from `LogOversizedDbCache` and adds functional test cases for integer and invalid non-integer `dbcache` values in `settings.json`. This allows parse exceptions from `GetIntArg` to propagate up to `AppInit`'s top-level exception handler, causing the node to exit with an informative error rather than aborting via `std::terminate`.",
  "problem": "If `settings.json` contains a non-integer or out-of-range number for `dbcache` (such as `300.5`), `GetIntArg` throws `std::runtime_error`. Because `LogOversizedDbCache` was marked `noexcept`, this exception triggers `std::terminate` during startup instead of being handled by `AppInit`.",
  "card": "Removes the noexcept specifier from LogOversizedDbCache so invalid dbcache values in settings.json produce a clean startup exit instead of a process abort. When settings.json contains a non-integer dbcache value, GetIntArg throws std::runtime_error, which hit the noexcept boundary and caused std::terminate to abort bitcoind during startup. Removing noexcept allows the exception to propagate to the AppInit handler, printing an informative error message and exiting with status 1.",
  "evidence": [
   "PR description and commit note uncaught exception crash during startup: 'libc++abi: terminating due to uncaught exception of type std::runtime_error: JSON integer out of range'",
   "The diff directly corroborates the mechanism: `LogOversizedDbCache` calls `CalculateDbCacheBytes` which calls `GetIntArg`, while the function was declared `noexcept`."
