+### Fixed
+- Auto-mode (`--auto`) now survives context compaction by persisting `workflow.auto_advance` to config.json on disk
+- Checkpoints no longer block auto-mode: human-verify auto-approves, decision auto-selects first option (human-action still stops for auth gates)
+- Plan-phase now passes `--auto` flag when spawning execute-phase
+- Auto-advance clears on milestone complete to prevent runaway chains
