Port Google Research's Harness^2 method layer (model weights frozen, only the surrounding harness is optimized): Propose-Probe-Compose with INV/DOM/AGG editors, parallel/sequential modes, per-domain experience library, anonymous-product selection, k<=3 hard cap and budget gate. Execution goes only through the existing control-plane API (upload -> task with idempotency key -> poll -> trace/cost -> cancel on timeout); no new server endpoints, no codex flags composed, tasks inherit the normal executor/sandbox/quota/audit path. Wiring lessons from four real rounds against production (project wwww, ledger task): HttpTaskClient retries transient disconnects and 502/503/429 (3 attempts); editors get a worked file-block example, an explicit <no-change> marker and one feedback retry (.fmt2) instead of silently accepting notes-only replies; run_task unwraps the server's result_text JSON envelope (text field holds the real reply) — without this, line-anchored file-block parsing could never see blocks the agents were actually emitting. Final round (real4) fully green: all stages landed, selection non-fallback, experience入库, probe delivers the correct signed total 85.15. Tests: 35 harness tests (17 method + 18 wiring incl. fake-control-plane full round, idempotent replay, retry, format retry, envelope round). Deliberate deviations from upstream are documented in docs/harness2.md (no network-unrestricted/sandbox-disabled defaults, auto_apply off, no benchmark/scorer, probe deliverable = final reply text).

"""用真实 codex 任务跑一轮 Harness² 改进(接线层 CLI)。
|
||
|
||
这会创建真实任务、花真实模型配额——所以默认只打印计划,不建任务:
|
||
先跑一遍不带 --yes 看计划,确认项目、任务数与预算无误后,再带
|
||
--yes 重跑。第一次请务必用测试项目,不要直接指生产项目。
|
||
|
||
密钥不走命令行参数(ps 可见):用环境变量 CODEX_API_KEY。
|
||
|
||
示例:
|
||
export CODEX_API_KEY='...'
|
||
python3 examples/harness2_run.py --base-url http://127.0.0.1:8765 \\
|
||
--project-id <test-project> --prompt-file task.md \\
|
||
--base-harness-dir ./my-base-harness --source-dir ./task-source \\
|
||
--mode parallel --k 1 --budget 5 --output runs/h2-real-1
|
||
# 看计划无误后,加 --yes 重跑(同一 run_tag 可断点续跑;想从头
|
||
# 重跑就换 --run-tag 或不传,让它自动生成新的时间戳 tag)。
|
||
|
||
base-harness-dir:一个目录,里面就是 harness 树(AGENTS.md、
|
||
.agents/、scripts/、.codex/……),按原样读入;不存在或 AGENTS.md
|
||
为空时直接报错,不跑。
|
||
source-dir(可选):原任务需要的源文件,会随 harness 一起 seed 进
|
||
每个探针任务的 worktree;与 harness 路径重名时 harness 优先。
