-**Node 24 is the primary CI target.** All tests must pass on Node 24. Node 22 (LTS) must remain backward-compatible — do not use APIs that are not available in Node 22.
+**Node 24 is the minimum and primary CI target.** All tests must pass on Node 24.
 
 | Version | Status |
 |---------|--------|
-| **Node 24** | Primary CI target — all tests must pass |
-| **Node 22** | Backward compatibility required |
+| Node 22 | EOL April 2027 — no longer a CI target; may still work but unsupported |
+| **Node 24** | Minimum required — primary CI target, all tests must pass |
 | Node 26 | Forward-compatible target — avoid deprecated APIs |

-- Version-specific features not available in Node 22
