### Performance Optimizations
- **Caching** - Bean descriptors and reflection metadata are cached for improved performance
- **Lazy initialization** - Resources and expensive operations are initialized only when needed  
- **Memory efficient** - Specialized collections like `LruHashMap` and `ArrayMap` for memory-conscious applications
- **Java 21 features** - Switch expressions and pattern matching for reduced overhead

        SMBUtil.writeInt2(0x0302, buffer, 4);

        // Negotiate context count (0 for non-3.1.1)
        SMBUtil.writeInt2(0, buffer, 6);

        // Server GUID (16 bytes of zeros)
        // Already initialized to zeros

        // Capabilities
        SMBUtil.writeInt4(Smb2Constants.SMB2_GLOBAL_CAP_DFS, buffer, 24);

        // Max sizes (reasonable values)

is a brief explanation of how they tie together:

1.  `envs/*` are lists of variables made with bash syntax. A user must set a
    `TFCI` env param pointing to a list of `env` files.
2.  `utilities/setup.sh`, initialized by all top-level scripts, reads and sets
    values from those `TFCI` paths.
    -   `set -a` / `set -o allexport` exports the variables from `env` files so
        all scripts can use them.
