PR-06 — RC Hooks Documentation (No RC Yet)

Goal

Prepare the VM for RC without implementing it yet.

Required Changes

• Document which VM instructions are RC-sensitive:

  • LocalStore
  • GateStore
  • stack pop / drop (if present)
  • frame end / FrameSync as safe points

• Document RC rules:

  • retain on handle copy
  • release on overwrite/drop

Tests

• Documentation test or unit assertion that the RC-sensitive list exists

---

STOP POINT

After PR-06:

• ir_core and ir_vm are fully decoupled
• Lowering is deterministic and placeholder-free
• VM ISA v0 is defined and stable
• VM runtime work may begin safely

Any VM changes before this point must be rejected.
