+# Implementation Spec: Round 12 — COMPLETE
+
+## Goal
+Self-healing resource pool (auto-reconnect) — remove per-call "is connection
+dead? rebuild" boilerplate.
+
+## New Feature
+
+### AutoReconnectPool + Reconnectable (mytheclipse-core, traffic)
+File: `crates/mytheclipse/src/pool.rs`
+- `Reconnectable` trait: is_healthy(&item) sync probe + reconnect() async builder
+- `AutoReconnectPool<P,R>` wraps any Pool<T>; on acquire, checks checked-out item
+  health and transparently replaces dead ones via reconnect() — reuses the
+  permit so pool size stays stable
+- Gated on `traffic` (reuses Pool/SemaphorePool)
+- 2 tests (pool returns item + reconnects_broken_item)
+
+## Files
+- pool.rs: +Reconnectable +AutoReconnectPool +test
+- lib.rs: export AutoReconnectPool, Reconnectable
+
+Build: exit 0. Tests: 0 FAILED. Clippy: 0 new warnings.
