Package assert holds dependency-free test assertion helpers usable from any package's tests.

Package cas holds the atomic content-addressed staging dance shared by baseline materialization and the kustomize stage cache: build into a sibling temp dir, atomically rename it into the final slot, and — when the rename loses a cross-process race — discard the temp and adopt the winner's already-finalized directory.

Package cli wires flate's command-line interface using cobra.

Package diskcache holds the pieces of the single-flight, mtime-LRU disk-cache sweep shared by the helm render cache and the kustomize stage cache.

Package format provides the table, YAML, JSON, and "name" output modes used across flate's CLI surface.

Package keylock provides per-key mutual-exclusion locks that honor context cancellation.

Package testrunner implements `flate test`.

Package testutil is shared fixture scaffolding for tests across the repo — kept minimal so each test file stays self-describing.
