Rod bearing failure - what to do?

I know my 2nd running in service was done properly, as I did it.
I also kept the rev limit relatively low whilst running it back in, then gradually increase the rev limit by 500rpm every 1000 miles until I’d hit 5,000 miles...then drove it as it was intended. I was also instructed not to keep it at the same revs in the same gear for mile upon mile, so made sure to cruise in 4th/5th/6th to vary the revs every 20-30 miles.
As I said earlier, there was zero sign of any particles in the oil or filter 2 weeks previously, and LOTS of particles/flakes visible 2000 miles later when we checked again.
I consider myself relatively lucky to get 140,000 miles on them, and we’d kept putting the job off due to other, more pressing issues coming up...such as broken post-cat O2 sensors which were seized into the cat after my little grass diversion on the last National, and having to customise ‘straight fit’ Brembo brakes that weren’t.
