Seeing that it is so difficult tracking the defect in the traditional ways...
A possible way to debug this: use some vibration(and maybe temperature) transducers. Install them in key points like clutch, clutch cylinder, gearbox. You need also the signal acquisition board. Basically you need to correlate the events(clutch engagement...) with the signal characteristics. When the grind happens if you can spot a delay somewhere(compared to normal cases) you have a more precise insight of what happens.
Such investigations are carried out routinely in engineering(there are even diagnose systems based just on vibration/temperature characteristics). I don't understand why Honda doesn't do it. Transducers downside is that they are kind of expensive (couple of hundred $ each at least) due to rare materials used and precise manufacturing. You need to take care how you use/install them.
