Where it lives

• Signature: src/builtins/io/__elephc_phar_set_compression.rs
• Lowering: src/codegen/lower_inst/builtins/io.rs:3797 (lower_elephc_phar_set_compression)
• Function symbol: lower_elephc_phar_set_compression()

Lowering notes

• Internal helper used by the built-in Phar / PharData support to change archive compression.
• Calls the native PHAR compression-control bridge and returns whether the update succeeded.

Runtime helpers

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