修正 SLO-1 的百分比与允许漂移轮数。
每日一轮时，一个自然月允许 1 个漂移轮的最高收敛率是 30/31，即约 96.77%。该规则无法同时满足“月收敛率 ≥99%”。请调整百分比或删除“允许 1 漂移轮/月”。

统一 SLO-3 的 P1 触发条件。
此行说明 escape_rate >0 即触发 P1。第 22 行和 scripts/sli-report.sh 的 PREV > 0 && CUR > 0 仅在连续两周均大于零时升级。首次出现正值时，文档与自动化会给出不同结论。请将此处改为“连续两周 >0 → P1”，或同步修改自动化。

验证 SLO-2 的 freshness 定义。
当前断言只验证文档中任意位置存在 SLO-2，并验证任意位置存在 convergence。即使 SLO-2 的 freshness 指标被删除，SLO-1 的 convergence 仍会使测试通过。请分别提取 SLO-1 和 SLO-2 的表格行，并验证前者包含 convergence、后者包含 freshness。

按新鲜度状态输出正确的比较符。
当 stale == "STALE" 时，条件是 age_h > stale_h。当前输出仍固定为 ≤，例如会报告 STALE（age=72.0h ≤48h）。请根据状态输出 > 或 ≤。

1. Infra runs count healthy 🐞 Bug ≡ Correctness
env_face_calc selects every butler-env-drift gate event without checking verdict, so an infra-fail audit event is treated as a reconciliation round and can become the latest fresh run. Because env-drift.py initializes drifts to 0 before failures, such a detector failure inflates convergence and reports drifts=0/freshness OK, masking that no successful reconciliation occurred.
Agent Prompt
## Issue description
Environment SLI calculations currently count `infra-fail` audit records as successful zero-drift reconciliation rounds.
## Issue Context
The producer persists its outcome in the ledger record's `verdict`; only completed `ok` and `drift-detected` runs should contribute rounds, latest-run state, convergence, and freshness. Infrastructure failures should remain separately visible and must not refresh SLO-2.
## Fix Focus Areas

- governance/env-drift.py[123-125]

2. Ledger integrity goes unchecked 🐞 Bug ☼ Reliability
The weekly report decodes the remote append-only ledger and immediately calculates SLI values without validating seq, prev_hash, or hash. A corrupted or rewritten but syntactically valid ledger can therefore publish fabricated convergence/freshness metrics even though this ledger format defines chain failures as untrusted data.
Agent Prompt
## Issue description
Validate the downloaded env ledger's hash chain before using any record for SLI calculations.
## Issue Context
`evidence_shadow.py verify` is the repository's existing fail-closed validator, and `evidence-query.sh` already applies equivalent validation before returning ledger-derived evidence. Keep a missing branch as the documented `absent` state, but expose a present invalid ledger as `INFRA` and do not emit apparently valid env metrics.
## Fix Focus Areas

- governance/evidence_shadow.py[97-119]
- governance/evidence-query.sh[87-100]

3. Monthly allowance contradicts target 🐞 Bug ≡ Correctness
SLO-1 defines monthly convergence as at least 99% while simultaneously allowing one drift round per month. With the documented daily reconciliation cadence, one drift round in a typical 30-day month yields only 29/30 = 96.7%, so the responsibility-boundary source gives incompatible pass criteria.
Agent Prompt
## Issue description
Make the managed-period SLO-1 percentage and allowed drift-round budget mathematically consistent.
## Issue Context
The document defines convergence as zero-drift rounds divided by total rounds and states reconciliation runs daily. Choose a percentage that permits one daily round per month, or retain 99% and state that zero drift rounds are permitted for normal monthly volumes.
