Live-tested Codex 0.149 through the proxy and found four defects:
- proxy: custom_tool_call_output.output is an ARRAY of input_text parts on
Codex 0.149+. The Responses extractor accepted only the string form, so
every real Codex tool turn had an empty live zone and the subscription
route compressed nothing (75-116 KB requests, zero savings). The captured
real request now compresses; regression test pins the array shape.
- proxy: the /chatgpt route never recorded compression eligibility, so the
CLI told every Codex subscription user "your agent never reached the
compression layer" even when routing worked.
- cli: codexNativeConfig ran the legacy table strippers before removing its
own marker blocks; the stripper swallowed the tables end marker, so the
block enable had just written failed its own re-parse as "corrupted" on
the next wrap and doctor reported drift forever. Markers come off first.
- cli: nativeHooksDocument matched caveman hook entries by exact command
string, so a binary path change (upgrade, moved install) appended a new
hook set per event instead of replacing it. Match on managed identity.
