## PR-11 — Cross-Layer Conformance Tests: Core→VM→Bytecode (HIP)

### Goal

Prove end-to-end determinism and stability.

### Required Tests

1. PBS snippet (or Core IR fixture) that:

* allocates a storage struct
* mutates a field
* peeks value

Assert:

* VM IR contains:

    * `Alloc(type_id, slots)`
    * `GateBeginMutate/EndMutate`
    * `GateStore(offset)`
    * `GateBeginPeek/EndPeek`
    * `GateLoad(offset)`
    * RC ops (retain/release)

2. Bytecode golden output for the same program:

* assert the exact bytes match the frozen ISA/ABI.

### Non-goals

* No runtime execution

---

## STOP POINT (Hard Gate)

* HIP access is fully deterministic
* RC events are explicit and testable
* HIP ISA/ABI v0 is frozen with golden bytecode tests

Only after this point may we implement/tune:

* Gate Pool
* Heap allocation
* RC counters + safe point reclaim
* Traps at runtime
