- Split the monolith into package/provider/fetch/merge/cache modules with the Resolver deciding install/adopt/update/merge/conflict outcomes - Three-way merges via git merge-file/diff3 against a content-addressed merge-base cache; conflicts go to a .picopackage-merge sibling - Tests for package, provider, resolver, merge, and cache - notes.md: update UX and signing design — diff-by-default, SSH signature identity pinning (TOFU), key changes as a hard stop, exit-code contract - Add CLAUDE.md; remove the pre-refactor exe/pppkg monolith and scratch files Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EiyJC73Mz8xZyCTvCEY8qn
