The watchdog leaves a runaway pass by longjmp from inside guest code, which skips the exits of every frame it leaves: generated functions' bb_defer cleanup, overlay_loader_call_native's unit depth, the native-shard stack and cycle-flush hook, the DMA kick's exec depth, and the dirty-RAM interpreter's active/phase/precise flags, resume latch and pending load. The checkpoint now saves all of it and the restore puts it back (bb_defer with the cycle freeze), as the scheduler and exception landings do for theirs. An overlay shard's unpublished pass cycles are flushed into the frozen clock at the landing so they never reach the live one. PSX_RENDER_PASS_VERIFY also checks that a pass which returned normally left the nesting balanced, since the restore would hide that. render_pass_stats gains nesting_repairs and the fault log names what the landing undid. render_pass_abort_test aborts a pass from five nested frames (real render_pass.c and psx_cycles.c, mock devices and presenter) and checks every value, the clock and RAM; it fails without this change.
