RUST-CI-031 coordinated encrypted client-UDP evidence slice.

Summary:

• Persist the focused parity-harness policy and bounded encrypted client-UDP slice.
• Record the causal build receipts, superseded evidence decisions, final immutable report, exact binary/source hashes, review finding and correction, and exact green gates.
• Keep MFC limited to diagnostics-oracle work, ed2k-server upstream-clean, and public soak evidence discovery-only.

Final evidence:

• Receipt: rust-mfc-client-udp-encrypted-20261102t223823z
• Report SHA-256: d7a35823b5e39a8d925ac6b3c7358348f6cdff7df832669aa1330d80d92c0471
• Coverage: 32/100 overall, 5/9 client-UDP.

Validation:

• Strict documentation publication gate passed.

• emulebb MFC diagnostics oracle: fix(diagnostics): preserve encrypted UDP wire bytes emulebb#191
• emulebb-build: fix(build): clean server staging within WSL emulebb-build#22
• Rust and ed2k-server have no source changes and intentionally have no PRs.
