lean-ctx Made FSRS Spaced Repetition and Wasserstein-Optimal Token Allocation the Default Context Policy
yvgude/lean-ctx v3.9.18 (August 8, 3,558 stars, Rust) promotes `CognitiveMode::Full` to the default for new installs and auto-migrates anyone still on `basic`, wiring an FSRS spaced-repetition scheduler, Wasserstein-optimal token allocation, graph expansion, verbosity learning and context prefetch warming into the production read path. It also adds `ctx_cognitive` as the project's 83rd MCP tool. Two fixes are worth noting for anyone writing MCP servers: the server previously exited on unknown JSON-RPC methods instead of returning `MethodNotFound` per spec, and `ctx_patch` batches applied partially instead of atomically.
