# CinderX A/B Run Slot

给 orchestrator 和 pyperformance runners 使用。它只负责 A/B 资源切分,不解释性能结果。

## Slot 内容

- baseline slot:commit、容器线、Python、CPU affinity、结果目录、日志路径。
- candidate slot:commit、容器线、Python、CPU affinity、结果目录、日志路径。
- 互斥资源:CPU set 不重叠,tmux pane 不共享,build dir 不共享,`run.json` 输出不覆盖。

## Baseline Source 门禁

- 先读取 `../using-cpython-optimize/references/baseline-source-contract.md`。
- baseline slot 必须绑定 `baseline_source_verified`:口径 baseline、提交 baseline、source path、commit/ref、`git status --short`、`patchlevel.h`、`SOABI` 和容器 bind mount 都已确认。
- 远程环境、容器线或 tmux pane 可用不等于 baseline 源码可信;不能把远程 workspace 当前源码直接当 baseline。
- 若 baseline ref 不明、dirty 状态未解释、bind mount 指向不明或混入 candidate editable install,返回 `baseline_source_untrusted`,不分配正式 A/B slot。

## 并行前检查

- verifier 已确认环境可复用或已 bootstrap。
- verifier 已确认 baseline source verified;只有执行环境 reusable 不够。
- baseline/candidate 只在目标变量上不同。
- 先读取 `../using-cpython-optimize/references/pyperformance-affinity-guidance.md`,确认 `--affinity` / `taskset` 使用当前可用 CPU,而不是逐字照抄用户命令里的不可用高核号。
- 绑核策略写清,例如 `--affinity=0-7` 与 `--affinity=8-15`,或 `taskset -c 0-7` 与 `taskset -c 8-15`。
- 分配前查 `nproc`、`lscpu`、`taskset -pc $$` 和容器 cpuset;baseline/candidate 的 CPU set 数量尽量一致且不重叠。
- 可用 CPU 不足以并行隔离时,改为串行执行,并让 baseline/candidate 复用同一实际 affinity。
- `cinderx-test` 与 `cpython-baseline` 使用场景明确。

## 反问 Gate

- baseline/candidate 的比较对象或唯一差异轴查证后仍不明确时,询问。
- source 未验证时先补证据;已知 ref 可隔离为干净 worktree,只有 baseline 含义不明或修复会覆盖用户产物时才询问。
- CPU set 无法并行隔离时默认串行,使用同一实际 affinity;若用户明确要求并行或固定核号,说明冲突后询问。
- tmux pane、build dir、结果目录可安全新建时直接隔离;不必询问是否先审计资源。

## 输出

返回两个 run slot、baseline source 状态、原始/实际 affinity、可用 CPU 证据和是否允许并行。无法保证 baseline 可信或资源隔离时,要求修复 baseline 或串行执行。
