Adopting LifeOS on a machine that already has a customized PAI install — how do you handle existing hooks?

[lexilexikon]

I was about to install LifeOS and expected it to be smooth. Before running the
installer for real I did a dry-run against my existing config, and found
something I'd like to sanity-check with you before I proceed.

My setup: I already run a heavily customized setup in ~/.claude — the PAI
predecessor plus a bunch of my own hook customizations. So this isn't a clean
machine.

What the dry-run showed: InstallHooks.ts copies the payload hooks into
~/.claude/hooks/ with a recursive cpSync (force-overwrite). 49 of the 83
payload hook files share filenames with my existing hooks (ISASync,
LoadContext, RelationshipMemory, SuccessClaimGate, …), so they'd be
overwritten by the LifeOS versions. settings.json is backed up first — but the
hook script files aren't. Nothing was actually lost since I only dry-ran it,
but a real --apply would have silently replaced my customized hooks.

My questions:

1. Is the installer intended for clean machines only, or is there a supported
   path for people who already have an existing / customized install?
2. If you've adopted LifeOS on top of an existing setup, how did you handle
   your own hook customizations — merge by hand, fork, sandbox first?
3. Would it make sense for the installer to back up (or skip) existing
   same-named hook files, the way it already does for settings.json?

Mostly I want to hear how you'd approach this before I touch my daily driver.
Thanks!

same challenge here, similar to v4-v5. my currently running solution approach hypothesis:

• MAP vanilla v5 -> vanilla v6 functionality. whats new, whats modified, what is just 'moved'
• DIFF vanilla v5 -> my v5
• APPLY DIFF to MAP

i'd love to be able to provide more specific prompts/skills/scripts for this, but I thought sharing my current concept may help/nudge enough now instead of a more refined solution 'someday'.

one more thing to add, which helped me from v4 to v5 a lot:
I've always (well, tbh, 80% of the time) made sure, that my modifications got covered by a regression Evaluation (/Evals), so focusing on migrating the Evals to v6 provdes a TDD-Kind of approach and will ease this a lot.

Ideally, you would have your AI work through that with you, which is why it's an AI install now. It should basically look at your current system, which might have deviated since your last version of PAI, and then look at the new hooks and everything and say, "Okay, here's what I think we should change."

My AI (Fable 5 at the time) had a very strong opinion that we should NOT change anything and do anything - because we diverged too much from the canonical version 5.0 - was pretty hard to "convince it" and by the time I did and it wrote down the whole plan - we were out of the weekly Fable credits and they renew July 9 which means I no longer get Fable 5 to help me migrate :)
