Strict Clippy --all-targets -- -D warnings: passed.
Cargo test --lib: 3 passed.
Installed release wheel, PYTHONMALLOC=debug: 61 passed on asyncio; 61 on uvloop.
Saved round4 baseline binary, expanded socket cases: 61 passed.
Separate Rust AddressSanitizer build: 61 passed on asyncio; 61 on uvloop.
ASAN_OPTIONS=detect_leaks=0; embedding Python and system libraries uninstrumented.
No ASan diagnostics; this is not a leak or complete conformance qualification.

Commands follow asan-round3-check.txt, with installed wheel at
/tmp/skirr-round4-installed and the same /tmp/skirr-asan-package setup.
New table entries cover absolute-form empty/escaped paths and mixed/malformed
CRLF boundaries. These protect equivalent behavior during refactoring, rather
than claim bugs in the previous release.
