Tracked<T> reactive state management with automatic dependency tracking for UI views. Self-contained and framework-agnostic; could be extracted into any Rust UI or state-management project. Demonstrates non-obvious skill in building fine-grained reactivity without a runtime.

Merkle tree construction and hashing for incremental codebase embedding sync, with batched leaf uploads bounded by count and byte limits. Solves the recurring problem of detecting changed files in a large tree and syncing only deltas; reusable for any file-tree synchronization or content-addressed storage problem.

Candle-based ONNX inference runner with a heuristic fallback, exposed behind an InputClassifier trait with confidence scoring. A clean, extractable pattern for embedding ONNX models in Rust applications without a heavy runtime dependency.

Server-Sent Events client transport for the Model Context Protocol with auth token support, built on reqwest. A reusable MCP client implementation that any Rust agent tool could adopt to talk to MCP servers.

Condition, a set-once async condition variable that wakes all waiters exactly once. Small, dependency-free, and trivially extractable; a clean primitive for one-shot async coordination that avoids the boilerplate of manual oneshot channels.

TransientHint shows short-lived footer notices (success/error/muted) with automatic expiry, aborting superseded timers so only one live expiry exists. A well-crafted, self-contained TUI component demonstrating correct async timer lifecycle management; reusable in any terminal UI.

Typed IPC service framework with a ServiceCaller abstraction and MockServiceCaller for tests with expectation verification. Decouples callers from transport, making the service layer unit-testable; a reusable pattern for local inter-process control in desktop applications.
