Global Rules (Binding)

1. No semantic leakage

   • ir_vm must not encode PBS semantics (no when, optional, result, etc.).
   • ir_core must not encode VM execution details (no stack slots, no offsets-as-pointers).

2. Feature freeze discipline

   • ir_vm is treated as a stable ISA.
   • Any change to ir_vm requires an explicit PR and review.

3. No placeholders

   • No LoadRef(0), no Nop as semantic stand-ins.
   • If something cannot be represented, the PR must stop and report it.

4. No creativity

   • Implement exactly what is specified.
   • Do not add sugar, shortcuts, or inferred behavior.

5. Tests are mandatory

   • Every PR must include tests validating the new surface.
