-
-## Briefing
-
-Execution switching must occur only at safepoints.
-
-## Target
-
-Switch coroutine only:
-
-* After FRAME_SYNC
-* After instruction completes
-
-Never mid-instruction.
-
-## Checklist
-
-* [ ] Switch only at safepoints.
-* [ ] No reentrancy.
-
-## Tests
-
-* Stress test switching under heavy loops.
-
-## Junie Rules
-

+Stress test outline (to add in PR‑7.9 or here if desired)

+Build a bytecode program with a tight loop containing arithmetic + occasional YIELD and ensure:
+◦
+Under tiny budgets (1–n cycles), pc progression is identical across runs.
+What I changed and why

+◦
+Switches (simulated by alternating between two VMs) occur only
+▪
+immediately after step() completes, or
+▪
+when run_budget returns FrameSync.
+◦
+No observable state change occurs when force‑switching between two VMs mid‑tick except at these safepoints.
