| 제목 | B200 migration launch blocked by self-visible lock |
|---|---|
| 궁금했던 점 | Why did the first persistent tmux launch stop before any B200 generation work? |
| 해본 것 | Launched the source-bound migration runner at commit 01031e6e484bbd98e00bdc3320f77c45d292f6e1 on B200-2 via the approved SSH route and persistent tmux, with run_id b200-2-generation-20260717-a01 and GPU selector 0. |
| 당시 조건 | All 8 B200 GPUs were idle before launch. The runner acquired experiments/runs/.weighted_slo_final.global.lock, then immediately reran its clean-tree gate before model preflight or GPU initialization. |
| 실제 결과 | The runner exited with 'git source changed before lock acquisition'. The lock owner.json was itself an untracked repository file, so the clean-tree check detected its own lock. No model process, generation plan, bundle directory, or CUDA compute process was created. The lock was released and the run ID remained free. |
| 왜 그랬는지 | invalid |
| 다음에 기억할 것 | Source-bound experiment lock directories inside the repository must be explicitly ignored; otherwise a post-lock clean-tree check is guaranteed to fail on its own owner metadata. |
| 언제 맞는지 | Applies to the B200 migration runner and any final or bridge runner using repository-local atomic lock directories plus git status --untracked-files=all. |
| 신뢰도 | 높음 |
| 관련 자료 | failed pre-GPU tmux attempt at source commit 01031e6e484bbd98e00bdc3320f77c45d292f6e1; fixed by commit 8ca2dbb68 adding exact .gitignore entries; no artifact or performance data produced |

Exact repository-local final and bridge lock directories are ignored so their owner.json files do not falsify the runner's post-lock clean-tree assertion.
