Gate Review: Remove Codex Workflow Selector

recommendation: REJECT

originalIntent

The user asked, in Korean, to revert/remove the opt-in workflow selector safely and surgically: "그거 revert 하셈 opt-in workflow selector. 안전하게 저 기능 없애셈 surgical 하게지워주셈". Prior context identified the feature as PR #5540, the opt-in Codex Light workflow selector.

desiredOutcome

Remove only the Codex Light opt-in workflow selector runtime surface:

delete packages/omo-codex/plugin/components/workflow-selector
delete packages/omo-codex/plugin/hooks/user-prompt-submit-selecting-lazycodex-workflow.json
remove plugin manifest/workspace/package-lock wiring
update tests to assert absence
preserve ultrawork, ulw-loop, rules loading, CodeGraph, start-work-continuation, and other Codex hooks
provide evidence-bound Codex QA, PR/CI/review evidence, and no scope drift

userOutcomeReview

Functional diff review supports the intended runtime outcome. The branch is code-yeongyu/remove-codex-workflow-selector at 00eea45130acbdafb967e84c78d1f777389d287d. The selector component directory and aggregate hook manifest are deleted, the aggregate plugin manifest now has only three UserPromptSubmit hooks (rules, ultrawork, ulw-loop), and targeted runtime search found no selector identifiers in runtime/plugin wiring.

The change appears surgically scoped: outside the deleted component and evidence files, the Codex plugin diff is limited to manifest/package wiring and focused test updates. Direct remove-ai-slops/programming pass found no new production abstraction, parsing/normalization, implementation-mirroring production code, or broad scope drift. The test edits are absence and preservation checks aligned with the requested removal, not unrelated test inflation.

However, the gate cannot approve because mandatory review evidence is absent. The supplied evidence folder contains QA logs and summary only; no code-review artifact, no manual QA matrix, and no notepad path/report were supplied. PR reviews/comments are empty. The final-gate instruction requires rejection when the code review report coverage for the skill-perspective and overfit/slop criteria is absent or unsupported.
