Lowered instruction tape with IR op index mappings and source origins:

PC	ASM	IR Op Index	Origin
0	`FUNC_DEF main()`	0	compiler
1	`ASSIGN x = 40 [local]`	1	compiler
2	`RET (x + 2)`	2	compiler
3	`FUNC_END`	3	compiler

Ran Ladder: Optimization passes disabled during inspection to preserve authored source identities (compile_passes: []).
