Opcode is Copy and serialized as a single byte in the binary format. Keep variants in a stable order; append-only.

Try = 67

? — Ok/Some → inner; Err/Null early-return from current frame.

Nop = 68

Halt = 69

CallDirect = 70

Direct call to a known chunk. operand = (chunk_index << 16) | arity. Stack: [func_slot_placeholder, args…]

Argc = 71

Push the number of arguments actually passed to the current frame.

Slide = 72

Keep the top value, drop the operand values directly below it. Used by match arms to discard the scrutinee temporary and the pattern bindings under the arm’s result. Appended last so the discriminants of every earlier opcode stay stable.
