Public API ledger

This page is the human-readable index of named exports from @open-matrix/core's root barrel and @matrix/test-utils. For finer-grained reference (every subpath, every type), see Core subpath exports. For deprecation status of specific symbols, see Deprecated APIs.

The source of truth is projects/matrix-3/packages/core/src/index.ts and projects/matrix-3/packages/test-utils/src/index.ts. When in doubt, read those files; this ledger is a navigable index over them.
