Postmortem method
Failed routes are valuable only when the report remains falsifiable, reversible, and free of sensitive data. Record:
- the original observation;
- the mutually exclusive hypotheses;
- the evidence that rejected the earlier conclusion;
- the trust boundaries changed by the attempted fix;
- the evidence that rollback was complete;
- the earlier point in the timeline where evidence should be captured next time.
For example, a Magisk boot problem requires a timeline of early counters, properties, key state, and module decisions. Reading 0 after Android finishes booting does not prove the value was 0 when the earlier decision was made. Binary patching is not a diagnostic method; first build repeatable observation and recovery paths.
