Performance - RemoteRoot gains an in-RAM read cache: small files (<=8 MiB) are cached whole on first read and served locally on repeat reads, keyed by path and validated against the mirror's (mtime, size). LRU-evicted to 256 MiB; dropped on invalidation and on local writes/truncate/rename. Removes a round-trip per repeat read. Stats gain read_cache_hits/misses/bytes. - Adds `mount --listen` so the client can accept the agent dialing in (used for Direction B, where a Windows agent reaches a WSL client via localhost forwarding without opening the firewall). Benchmark (scripts/bench-real.ps1, bench/real_world.md, bench/RESULTS.md) - Measures both directions vs the OS cross-boundary path and the native floor. - Direction A (Windows -> WSL ext4), 3000 files: \\wsl.localhost 104 ms walk / 2856 ms read vs wsldrive 39 ms / 538 ms => 2.7x / 5.3x faster. - Direction B (WSL -> Windows NTFS): /mnt/c 119 ms walk / 5853 ms read vs native 10 / 118 ms. wsldrive serves metadata from RAM; cold bulk reads are latency-bound (read-ahead/pipelining is the documented next step). Tests: read-cache agent test (miss/hit/slice/evict-on-write). 96/96 Windows, 95/95 Linux, zero warnings. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Client-side read cache (repeat reads served from RAM);
mount --listen; and a real-world benchmark. Direction A: wsldrive 2.7x/5.3x faster than \wsl.localhost. See bench/RESULTS.md.
