 client: the daemon publishes a typed Eve/CultUI surface, and any compatible
 runtime can lower that surface where it needs to live.
 
+## Entry Points
+
+- C# reference runtime: `src/` (`GameCult.Caching`, `GameCult.Networking`,
+  `GameCult.Mesh`, `GameCult.Geometry`, `GameCult.Unity`). Build and test with
+  `dotnet build CultLib.sln` and `dotnet test CultLib.sln`.
+- Other runtimes, wire-compatible with the C# CultCache: `packages/cultcache-ts`,
+  `cultcache-py`, `cultcache-rs`, and the CultNet and CultMesh packages beside
+  them under `packages/`; portable math in `packages/cultmath`.
+- Smallest working path: `src/GameCult.Mesh/docs/durable-node-quickstart.md`.
+  Application path: `src/GameCult.Mesh/docs/getting-started/README.md` and
+  `samples/eve-two-runtime`.
+
+## Live And Planned
+
+Live: typed CultCache persistence, CultNet schema-v0 transports and native RUDP,
+CultMesh nodes with Verse discovery, shard replication and authority leases,
+the geometry documents, and CultUI for Unity. The browser client boundary
+(`packages/cultmesh-browser`, `GameCult.Networking.WebSockets`) is proven on
+loopback under an explicit `local-development` trust policy by
+`samples/eve-browser-network`.
+
+Planned: a complete public Verse proof over deployed infrastructure; the
+remaining gates are listed in `src/GameCult.Mesh/docs/browser-verse-transport.md`.
