What permissions must I ensure after manually copying contents into ~/Library?

For reasons (Time Machine sparsebundle broke itself irrevocably when I actually needed to restore...) I need to **manually copy the contents of ~/Library** from a manual backup, to an existing user directory on Monterey. I'm copying everything except Application Support. When I do this using Copy Exactly in Finder on Ventura... - ...the owner of the items seems correct (uid 501) - ...Finder will show the "denied" symbol over the folders (my account name and uid are identical in Ventura and Mojave). - ...logging in with the user in Mojave shows dozens of "need to repair your Library" password prompts, and all account specifics have been reset (settings, etc.) These "repairs" did nothing from my perspective. Obviously permissions aren't correct despite trying to preserve everything as much as possible. The initial backup was copied like this: Source (APFS) → "Exactly" to HFS+ → cp -a to Btrfs (in Ubuntu 23.04) The reverse process is used when restoring. Did I lose ACLs in that process, or what could the problem be? **Can it be fixed?** ----------- As mentioned, I would've restored from Time Machine if it hadn't failed the ultimate test of reliability by destroying its own file system during a restore and then fsck putting the final nail in the coffin by saying it can't be repaired.
