+# Gate: tmux Shift+Enter Fix — Correctness Review
+
+## Verdict
+- [decision] APPROVED — REVIEW_SCORE: 0
+
+## Findings
+- [observation] No CRITICAL or WARNING issues found.
+- [observation] `bind-key -n S-Enter send-keys "\n"` is semantically correct for the stated intent.
+- [observation] Prerequisite `extended-keys on` is present and positioned before the binding.
+- [observation] Terminal features line (`xterm-kitty:extkeys`) enables the terminal to report extended key sequences.
+- [observation] No conflicting bindings exist in the config.
+- [observation] Config ordering is correct — prerequisites before the binding.
+
+## Evidence Checked
+- [observation] Line 8: `set -s extended-keys on` — enables tmux to recognize modified keys like `S-Enter`.
+- [observation] Line 9: `set -as terminal-features 'xterm-kitty:extkeys'` — tells tmux the terminal supports extended keys.
+- [observation] Line 10: `bind-key -n S-Enter send-keys "\n"` — root-table binding, sends literal newline. Correct.
+- [observation] No other `Enter`-related or `S-Enter` bindings exist that could conflict.
+- [observation] `-n` flag correctly targets root table (no prefix key needed).
