Native API proof with production summary resolver:
Native codex-cli 0.163.0; disposable CODEX_HOME; no authenticated/model turns.
{"case":"unset","config":null,"origin":null,"selectedSummary":"auto"}
{"case":"user concise","config":"concise","origin":"user","selectedSummary":"concise"}
{"case":"user none","config":"none","origin":"user","selectedSummary":"none"}
{"case":"session detailed","config":"detailed","origin":"sessionFlags","selectedSummary":"detailed"}

Limits: no authenticated model/Bedrock turn, browser UI, macOS, Windows, iOS, Android, or Electron desktop verification. Nonvisual backend change; screenshots do not establish its behavior.

Final reviewed revision: removed recorder config/read to avoid capturing ambient configuration; trimmed unused layers and replaced a redundant row with packagedDefaults coverage.
