Function default_memory_manager_doctor_report 

pub fn default_memory_manager_doctor_report() -> DefaultMemoryManagerDoctorReport

Build a preflight and runtime diagnostic report for the default runtime.

The doctor report can be collected before bootstrap, after bootstrap, or after a failed bootstrap attempt. Stable-cell, commit-recovery, declaration, range-authority, validation, ledger, and live memory-size status are collected into one serializable report. Recoverable problems are reported in fields rather than returned as errors.
