"""Tests for agent.replay_cleanup — shared replay-tail sanitizers.
These functions were extracted from gateway/run.py so every resume surface
(messaging gateway AND TUI/WebUI gateway) strips poisoned tool-call tails the
same way. Regression coverage for #29086 (WebUI session permanently stuck
because the dangling tool-call tail was replayed on every resume).
