Folderbase Core v0.5.0-rc.1

Folderbase Core v0.5.0-rc.1 is the first installable release candidate for the ordinary-folder 0.5 architecture. Any ordinary folder can remain ordinary while .folderbase/ adds durable identity, local versions, opaque-file capture, optional narrative adapters, templates, sharing primitives, and crash-safe reorganization transactions.

This is intentionally a prerelease. Protocol 0.5 remains a sealed candidate (status: candidate); released protocol 0.4 remains immutable.

• extracted packages: Core 65 files, CLI 10 files; compile, tests, mutation proof, optimized install, and outside-checkout use passed
• strict formatting, clippy, rustdoc, workspace tests, public-surface, CI-policy, digest-vector, and package gates passed on the exact release tree

# folderbase 0.5.0-rc.1

The annotated public tag currently peels to the exact reviewed commit. Git tags can be moved or deleted by repository administrators unless protected separately, so the commit-pinned install is the stronger reproducibility pin.

The repository at the exact commit is the normative candidate protocol bundle. This release does not claim stable protocol 0.5, crates.io publication, managed Cloud availability, or production sync readiness.
