 # Status
 
-**Overall: complete (2026-10-12); final polish in progress (P3 leftovers, Windows runtime tests under Wine).** Ghostty 1.3.1's Zig code is fully ported to Rust: Linux/GTK app (built, tested, verified at runtime, pixel-identical to the original), libghostty + libghostty-vt C APIs (ABI-checked), WASM (node-tested), macOS and Windows code paths (compile-checked with clippy -D warnings; not runnable here). 3584 tests; terminal core differentially fuzzed against Ghostty's Zig code (390k+ cases, 0 divergences); config/CLI output byte-identical to the installed Ghostty. Review rounds stopped after RV18 per the stopping criterion in PLAN.md. Intentional deviations: DEVIANT_FIXES.md; remaining minor differences: KNOWN_DIFFERENCES.md.
+**Overall: complete (2026-10-12).** All of Ghostty 1.3.1's Zig code is ported to Rust. Linux/GTK app: built, tested, verified at runtime, pixel-identical to the original. libghostty + libghostty-vt C APIs: ABI-checked against the unchanged headers, Ghostty's C/WASM examples run. WASM: node-tested. Windows: runtime-tested under Wine 11 (2758 tests incl. ConPTY). macOS: compile-checked with clippy -D warnings (cannot run here). 3602 native tests; terminal core differentially fuzzed against Ghostty's Zig code (390k+ cases, 0 divergences; panic hunt 0 panics); config/CLI output byte-identical to the installed Ghostty. Intentional deviations: DEVIANT_FIXES.md (fix-deviant commits); no known unfixed differences (KNOWN_DIFFERENCES.md lists only unverifiable coverage).
