Is my Linksys WRT32X beyond repair?

The boot log includes the phrase DRAM initialization failed! - which sounds pretty terminal

There's other failures as well, however they seem to match "fails" in the OEM Bootlog

Note: this was running OpenWRT 19.07.8

Also, no lights (brief flicker on power up)

here is the boot log

It's served me well for a few years - I'd hate to have to throw it out (despite the bad rap it gets for its wi-fi issues)

Given that you have already opened the device to gather the serial log, take a good look at the capacitors on the board (check for leakage, bulging caps, etc.) - another easy test would be trying a different (matching) power supply (and/ or measuring its voltage under load). If neither of these steps help, the situation probably won't look good (trying kwboot recovery might be a last hope attempt, hoping that you'd 'just' have an issue with the installed bootloader).

Already tried that - the upload fails at about 9-10% - I read somewhere else similar issue on a WRT1900AC - kboot basically does the same as in that thread -

However, that seems to have gone unresolved

There's no obvious bad caps or any damage at all

I decided it was beyond repair, so investigated rather more brutally - i.e. pried off the heatsinks etc

There wasn't any obvious damage, however there did seem to be some moisture under the heatsinks

I'm declaring it router del muerto
