docs(exploration): Phase B — suminerProxy fork eval + upstream issue classification (Codex R1-R5 0 수렴) - #6

…분류 (Codex audit 기반)

## Phase B 결과 — 평가 + 분류 doc 2건 (doc-only, 코드 변경 X)

본 fork (opnd-io) 가 daily-evolve digest (2026-05-28) 의 다음 영역 처리 가능성 평가:

### docs/exploration/2026-05-28-suminerProxy-fork-evaluation.md

`gh api repos/openai/codex-plugin-cc/compare/main...suminerProxy:codex-plugin-cc:main`
으로 22 commits 비교. 가치 분포:

- **HIGH 6건 cherry-pick 후보**: c30b664 (NDJSON event stream API) + a3f4181 (notification stream hook) + 9332c29 (event stream + stall watchdog) + 4baaf19 (token usage in /codex:status) + 6871973 (CODEX_EVENTS_RAW=0 PII strip) + 30f3a26 (task-stream push + /codex:stream slash command)
- **MEDIUM 5건**: 3a0ae2d / 45a24f0 (Codex CLI 0.131 schema gaps) / 1014d10 (rescue defaults bg + compact recovery) / 2f3a397 (stuck-phase integration test) / f701412 (review unblock) / d224805 (review isolate)
- **LOW 1건**: 5e8100a (test isolation, 우리 openai#338 와 angle 다름)
- **N/A 11건**: release / merge

다음 sprint plan: NDJSON event stream 묶음 (1주+) / raw payload strip (1일) / token usage (2-3일) / task-stream push (1주+) cherry-pick 우선. license 확인 + Apache 2.0 §4-b NOTICE attribution 필수.

### docs/exploration/2026-05-28-upstream-issue-classification.md

upstream openai/codex-plugin-cc 의 30+ open issue 분류:

**본 fork 가 이미 cover (5건, gh issue 답글 후보)**:
- openai#281 (after logout/login fail) — PR #4 broker busy/timeout 분기
- openai#282 (Desktop history isolate) — v2.0+ plugin home 격리
- openai#288 (sendBrokerShutdown timeout) — broker-lifecycle.mjs L46-48 + L65
- openai#337 (spawn shell:true Windows) — process.mjs buildCommandInvocation cmd.exe 래핑
- openai#342 (setup loggedIn:false when broker busy) — PR #4 broker busy 분기 직접 cover

**부분 cover (3건)**: openai#310 (zh-TW Big5 locale) / openai#286 (broker race) / openai#308 (large prompt rejection)

**HIGH port 후보 (8건)**: openai#350 codex-rescue empty output / openai#349 Windows sandbox / openai#345 SessionEnd kill / openai#336 CreateProcessAsUserW 1312 / openai#333 argv parsing / openai#331 MSYS path / openai#330 IPC deadlock / openai#295 CreateProcessAsUserW 1920

**MEDIUM/LOW (19건)**: openai#354 feature / openai#329 VS Code / openai#324 rescue stub / openai#321 / openai#320 / openai#309 PARTIAL / openai#306 rate limit infinite cycle / openai#304 sandbox / openai#298 max findings (우리 --max-findings cover) / openai#287 PATHEXT (openai#337 와 유사) / openai#285 (solution doc 있음) / 등

## 다음 sprint plan (사용자 결정 영역)

| 우선 | 작업 | 추정 |
|---|---|---|
| HIGH | 본 fork cover 5건 upstream gh issue 답글 등록 (가장 quick win) | 0.5d |
| HIGH | upstream HIGH 8건 port — 가장 trivial 2건 fix 시작 (openai#333 argv / openai#331 MSYS) | 1주 |
| MEDIUM | suminerProxy NDJSON event stream 묶음 cherry-pick | 1주+ |
| MEDIUM | suminerProxy raw payload strip + token usage | 3-4일 |
| LOW | upstream-pr 92건 분류 | 1주+ |

본 PR 은 평가 + 분류 doc 만. actual fix / cherry-pick 는 별 PR (사용자 결정).

## CHANGELOG

- 2 docs/exploration/ entries 추가 (suminerProxy + upstream issue 분류)
- 기존 verified-no-change 항목 (openai#288 openai#337) 유지

## 검증

- doc-only 변경 (코드 X) — npm test 회귀 영향 없음
- 본 fork 의 코드 baseline 변화 없음 — Phase A merge 후 main 와 정합
