Standalone handoff for a follow-up investigation. Records the symptom, a full
reproduction (including the two rig-tooling blockers and the CachedCall-vs-Call
detail needed to generate load at all), the isolation evidence, a code map of
the LocalDb connection model, four ranked hypotheses, and acceptance criteria.
Not root-caused. Highest-value next step identified: capture the SQLite EXTENDED
result code (logs only carry the generic primary code 10), and run the load with
LocalDb:Path off the bind mount to partition environmental vs library causes.
