Where it lives

• Signature: src/builtins/pointers/buffer_len.rs
• Lowering: src/codegen/lower_inst/builtins/buffers.rs:20 (lower_buffer_len)
• Function symbol: lower_buffer_len()

Lowering notes

• Lowers buffer_len() through the direct buffer opcode helper.

Runtime helpers

No direct __rt_* helpers captured — the lowering is inlined or routes through another builtin.
