part 5 修复 1:单元内 health 恒 false——default_codex_bin() 回落 shutil.which
RETEST4 新发现 1:单元内无 CODEX_BIN、无 HERE/bin/codex 时
default_codex_bin() 返回裸 "codex",run_health_check 的
os.path.exists("codex") 以相对路径判恒为 False,health 的 ok
恒 False(execpath4、p2_7v4、P1 resident_health、P1B 两 call
全因此失败;定界探针证实单元内 which codex 就是
/usr/local/bin/codex,加 CODEX_BIN 前缀即 rc=0 且 ok=true)。
三选一取 (c) 回落 shutil.which("codex"):
- (a) CODEX_BIN 进 FORWARD_ENV_ALLOWLIST:要执行器与 chv-cell
两边接线、还得在客机环境里定一个单元内路径,改动面大,且
只修执行器驱动的调用,直接跑 host.py 的 health 修不到。
- (b) _guest_host_command 显式加 --codex-bin:把客机镜像路径
硬编码进执行器,同样只修执行器驱动的调用。
- (c) 单点修 host.py:health、Server、automations 全部调用方
直接受益;PATH 里找得到即返回绝对路径,找不到仍返回裸
"codex"(行为与旧代码一致,零回归面);不硬编码任何路径。
新测试 tests/test_host.py::DefaultCodexBinTest(4 项):模拟
单元内环境(PATH 含 codex、cwd 不含 codex、无 CODEX_BIN)
断言返回绝对路径、CODEX_BIN 优先、处处无 codex 时仍返回裸
"codex"、以及该解析下的 run_health_check ok=true。
