Pull request overview
Introduces the metrics dashboard policy “single source of truth” by adding a dedicated governance policy file for thresholds/data-source declarations and a gate-style schema self-test to keep the policy complete and drift-free.
Changes:
- Added
governance/policy/metrics.yamldefining dashboard metric thresholds, guardrails, and explicitpendingdeclarations for missing data sources. - Added
governance/tests/test-metrics-policy.shto validate required keys, threshold directionality, pending honesty, and product/quota schema againstREPOS.yaml.

1. Python探测可误选版本 🐞 Bug ☼ Reliability
test-metrics-policy.sh 的解释器探测只验证“能 import yaml”，可能选中 Python2（或其他不支持 f-string 的版本），随后内嵌 Python 代码使用 f-string 会直接语法错误导致测试失败。该探测同时把 py -3 拆成了两个候选（py 与 -3），无法真正尝试 Windows Python launcher 的 py -3 路径。
Agent Prompt
### Issue description
`governance/tests/test-metrics-policy.sh` picks a Python interpreter by only checking `import yaml`. It can therefore select Python 2 (or another incompatible version) and later crash because the embedded script uses f-strings. Also, the loop lists `py -3` as two tokens (`py` and `-3`), so it never actually tries the Windows launcher `py -3`.
### Issue Context
- The embedded Python code uses f-strings (Python 3.6+).
- The current probe is: `"$c" -c 'import sys, yaml; print("ok")'`.
### Fix Focus Areas
- governance/tests/test-metrics-policy.sh[17-28]
- governance/tests/test-metrics-policy.sh[36-41]
### Suggested fix approach
1) Change the probe to explicitly require Python 3.6+ (or your org baseline, e.g. 3.8+):
- `"$c" -c 'import sys; assert sys.version_info >= (3, 8); import yaml; print("ok")'`
2) Handle `py -3` as a command-with-args (array), e.g.:
- `PY_CMD=(python3)` / `PY_CMD=(py -3)` and execute as `"${PY_CMD[@]}" ...`
- Try `py -3` explicitly in a separate branch before/after trying `py`.
3) Ensure the selected interpreter command is used consistently for the main `"$PY" - ...` invocation (may require switching from scalar `PY` to array `PY_CMD`).

2. Mktemp失败未fail-fast 🐞 Bug ☼ Reliability
test-metrics-policy.sh 未检查 mktemp -d 是否成功；在极端情况下 TMP 为空时，重定向 >"$TMP/out.txt" 会变成写入 /out.txt（或其他非预期位置），造成测试副作用并掩盖真实失败原因。
Agent Prompt
### Issue description
`TMP=$(mktemp -d)` is not checked for failure. If it fails, `$TMP` may be empty and subsequent redirects like `>"$TMP/out.txt"` can write to an unintended path (e.g. `/out.txt`).
### Issue Context
The script runs with `set -u` but not `set -e`, so a failing `mktemp` won’t stop execution automatically.
### Fix Focus Areas
- governance/tests/test-metrics-policy.sh[26-28]
### Suggested fix approach
- Change to:
```bash
TMP=$(mktemp -d) || { echo "::error::mktemp -d failed"; exit 2; }
trap 'rm -rf "$TMP"' EXIT
```
- Optionally also validate `[[ -d "$TMP" ]]` before using it.

py -3 候选未生效：未加引号导致词分割。
for c in ... py -3 把 py 和 -3 当成两个独立候选。脚本会探测 py（Windows launcher 默认版本，可能就是注释里提到的 stub），再探测不存在的命令 -3。注释声明的 py -3 意图没有实现。带参数的候选需要数组调用。
CI 恒有 python3，所以 gate 不受影响；仅本地探测垫片失效。

or [] 会让 falsy 非列表值静默过测。
第 100 行先做 or []，再在第 101 行判 isinstance(..., list)。如果 entries 写成 0 或 ""，它会被换成 []，类型断言恒真，畸形记录位不会红。先取原值再判类型可以关掉这个通道。
