Recovery steps for hiro and ando.

bitcoin v22.0
LND version v0.15.5
chantools v0.10.6

1) The ddrescue yielded channel.db files for both nodes ando and hiro. Starting the node with these channel.db files reveals the corruption [1].
2) chantools compactdb command failed
3) chantools summary command succeeded, yielding the correct description of 627 channels for ando and 134 channels for hiro with the latest local and remote balances.
4) chantools forceclose (without publish) succeeded, yielding the correct listing of 580 closed channels and 47 open channels for ando, 129 closed channels and 5 open channels for hiro.
5) chantools walletinfo was used to extract the BIP32 HD root key
6) chantools forceclose (with publish) with the BIP32 HD root key was used to generate and submit all remaining force close transactions
7) Waiting for the timeouts to move all the remaining balances off the nodes
8) Recovery succeeded 100%

Finishing putting together the infrastructure for the new node.
