docs(devlog): record the three-issue round, including the blocked verdict on #2156

[lidge-jun]

Summary

Records the three-issue round — #2152, #2157, #2156 — including the one verdict that is not a fix.

Two shipped (#2178, #2179). The third is honestly blocked, and the record says why rather than shipping something adjacent and calling it done.

Three things worth reading here:

Two of #2152's own premises were wrong, and the fix follows the evidence instead. Group 1 was not "the case budget is too small" — A-reduced failed at 79,978 ms against a 150 s ceiling, so the outer budget was never the constraint; the abort came from an unscaled 10 s AbortSignal firing from inside. Group 2 was not "an unprivileged Windows user cannot create symlinks" — the runner can, and the cases then failed on Unix mode semantics a Windows directory cannot satisfy, which is what makes the platform skip correct rather than masking.

The Windows crash retry keyed on the wrong signature, and this repository had already written down why. 050_windows_ci_flake_rca.md:172 says not to anchor on panic(thread, because Bun emits both that and panic(main thread) for the same failure. Probed: the numbered form matches, the main-thread form does not. The retry would have failed the shard on roughly half the crashes it exists to absorb, while looking correct. Three copies of that list had drifted; the contract test now pins the sync itself, not the text.

#2180 did not fix #2156, and no longer claims to. A stall abort emits response.incomplete / upstream_stall_timeout from a path the bridge has already closed; the reporter's error comes from the adapter reading EOF with tool calls pending. Different path, different frame. The heartbeat fixes a real false-stall hazard on its own, and exposed a second defect — the terminal guard retaining per-delta heartbeats — which is fixed with it. #2156 stays needs-info with a specific question asked, because the adapter is reporting truthfully and what cannot be told from here is why that stream ended for ocx and not for Pi.

Verification

At the branch tips, on ssh lidge:

• fix(ci): give the Windows leg the budgets and the crash retry it never had #2178 — bun test 13719 pass / 15 skip / 0 fail; tests/ci-workflows.test.ts 132 pass / 0 fail.
• fix(openai-chat): heartbeat while buffering tool-call deltas #2180 — bun test 13722 pass / 15 skip / 0 fail; focused trio 112 pass / 0 fail.
• bun x tsc --noEmit exit 0 and bun run privacy:scan passed on both.

📝 Walkthrough

Walkthrough

The devlog consolidates findings for three bug issues. It records Windows CI diagnoses, crash-retry and shell-command changes, shadow-helper attribution, provider-stream investigation status, terminal-event retention handling, and verification results.

Changes

Bug backlog consolidation

Layer / File(s)	Summary
Windows CI findings and crash retry devlog/_plan/260820_bug_pr_backlog_consolidation/110_three_bug_issues.md	Lines 1–53 document corrected Windows diagnoses, synchronized Bun crash signatures, the contract test, and hasShellCommandHead handling for piped commands.
Observability and provider-stream status devlog/_plan/260820_bug_pr_backlog_consolidation/110_three_bug_issues.md	Lines 55–94 record shadow-helper attribution, heartbeat buffering, bounded terminal-event retention, and the remaining provider-stream evidence gap.
Verification record devlog/_plan/260820_bug_pr_backlog_consolidation/110_three_bug_issues.md	Lines 96–103 record pull request verification, TypeScript compilation, privacy scanning, and focused test results.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: 🟡 Moderate · up to 40249

The devlog records the terminal-stream fix as complete, but retained per-delta events can still grow without a bound, leaving the documented outcome incomplete and potentially masking runtime growth; this should be resolved or explicitly accepted before merging.

리뷰 · 우선순위 34 / 80

docs-only임. devlog/_plan/260820_bug_pr_backlog_consolidation/110_three_bug_issues.md 한 장 추가한 거고, 본문이 가리키는 코드는 이미 dev 649912c09에 들어와 있음. #2178 Windows CI, #2179 Logs intercepted-helper, #2180 openai-chat heartbeat가 붙은 뒤라서 이 PR은 제품 경로를 안 건드림. 점수 낮게 줌. 기록용임.

#2152 쪽 서술은 지금 워크플로랑 맞음. .github/workflows/ci.yml Windows/macOS 레그가 둘 다 Internal assertion failure로 잡고, scripts/ci/run-bun-test-batches.sh의 is_bun_runtime_crash랑 같은 리스트임. tests/ci-workflows.test.ts가 그 싱크 자체를 핀해서 panic(thread로만 키 잡으면 깨지게 해놨음. 그 RCA 맞음. panic(main thread)를 놓치면 재시도가 반만 먹는다는 지적도 맞음. 다만 문서 스스로 말하듯 45s 예산이랑 Git Bash PIPESTATUS, 러너 위 windows_skip은 workflow_dispatch 없이는 로컬이 증명 못 함. 그래서 #2152 이슈는 아직 열어두는 게 맞음. 닫지 마셈.

#2157은 gui/src/pages/Logs.tsx에서 shadowCallRewrittenFrom 있을 때만 뱃지/필터가 켜짐. 대시보드 절반은 맞음. 헬퍼 요청 자체를 줄인 게 아니라 보이게 만든 거라서 이슈 본문은 그대로 열려 있는 게 자연스러움. ㅇㅇ

#2156 BLOCKED 판정이 이 문서의 핵심임. src/adapters/openai-chat.ts 1746 근처가 tool-call delta마다 heartbeat를 쏘고, 주석이 이미 "found while investigating #2156, but it is NOT that bug"임. 스톨은 response.incomplete / upstream_stall_timeout이고 리포트 에러는 reader.read() EOF + pending tool calls라서 경로가 다름. guardTerminalEventStream이 heartbeat를 seen에 안 넣는 것도 이미 src/server/responses/terminal-guard.ts:202에 있음. 하트비트로 #2156 Closes 걸면 안 됨. 잘 뺐음.

해결방안: 이 PR은 그냥 머지하면 됨. types.ts/config.ts 스플릿이랑 무관해서 rebase 필요 없음. #2156은 SSE 캡처 오기 전엔 고치지 말고 열어두고, #2152는 Windows workflow_dispatch 한 번 돌려보기. 남은 스플릿 무효 PR들은 리베이스 말고 닫으셈.

The historical record is useful, but the current exact head 402490278 states that the terminal-guard retention problem was already fixed in the same PR. That is not accurate on current dev or in this docs-only diff.

Two changes are required before this record is durable:

1. Add a language tag such as text to the diagnostic fence at line 31.
2. Rewrite lines 77–81 to distinguish the two event classes. #2180 stopped retaining heartbeat, but guardTerminalEventStream still retained every tool_call_delta, including arbitrarily large argument fragments. The separate runtime fix is now #2195; it passes both heartbeat and tool_call_delta through without adding them to seen and includes the focused regression. Please describe that as separate follow-up work rather than as already fixed in this docs PR, and update the verification section so it does not attribute #2195 results to #2180.

No product-code change is needed in this PR. Once the record matches the actual commit boundaries and the exact-head docs checks remain green, I can re-review it. This remains docs-only and has no Go counterpart.
