Six tasks:
1. Add exception-surfacing ContinueWith in WbMeshAdapter.IncrementRefCount
for EnvCell ids when ProbeIndoorUploadEnabled is on. Logs
[indoor-upload] FAILED + [indoor-upload] NULL_RESULT.
2. Capture procedure: user walks Holtburg with the probe on; analyze log.
3. Write cause report documenting the captured exception type(s).
4. Apply targeted fix (4a/4b/4c/4d sub-shapes for the 4 most-likely causes
— choice driven by Task 2's data). Or 4d: re-design if cause is none
of the above.
5. Verification: re-capture confirms completed lines, user visually
confirms floor in Holtburg Inn.
6. Roadmap update.
Tasks 2 and 5 are user-driven (must walk the client). Tasks 1, 3, 4, 6
can be subagent-dispatched.
