 # rpctl

 ```

 `--bundle` 目录需要包含 #100 runtime bundle 的 `bin/`、`lib/`、`fixtures/`、`scripts/` 和 `versions.json`。不要使用早期 precheck 目录作为标准 bundle，因为它可能缺少 FORT 运行所需动态库。

+`--rpki-prover-image` 是可选项；不配置时原有四款 RP 仍可运行，但启动 rpki-prover 会明确报错。配置后 `init` 会复制并加载离线镜像，校验宿主机和镜像均为 `amd64`，确认 tag 为 `rpki-prover:6857d4bf`、版本为 `rpki-prover-0.10.1`，并将 image ID 与 archive SHA-256 写入 `config.json`。运行时不会在线拉取镜像。

+rpki-prover 的 `run-meta.json` 和 `view` 同时记录 VRP 原始行数与按 `(ASN, prefix, maxLength)` 去重数。其当前 CLI 不输出 VAP，所以统一显示 `n/a`，不是 `0`。max RSS 是容器全部相关 PID 的 RSS 峰值汇总，不是短暂 Docker client 进程的 RSS。

+# verification-only 使用说明
+
+`verification-only` 用于复核启用验证缓存的最新成功 normal run。它冻结当前仓库视图，关闭 PP、ROA、child certificate cache、prefetch、VCIR 持久化和网络访问，在源 CIR 的同一验证时间重新执行完整验证，并比较 CCR 的 MFT、VRP、VAP、TA、router key 五类 state digest。
+
+## 前提
+
+- 源 run 必须是当前 state DB 对应的最新成功 normal run。
+- 源 run 必须包含 `input.cir`、`result.ccr`、`run-summary.json` 和 `validation-contract.json`。
+- state root 必须包含 `db/work-db`、`db/repo-bytes.db` 和 `meta/current-state-binding.json`。
+- 源 normal run 必须启用至少一种验证缓存；仅启用 transport prefetch 不算验证缓存。
+- verification-only 与 normal soak 共用 `state/locks/state-execution.lock`，不能绕过 wrapper 并发执行。
+
+## 执行
+
+在 portable package 根目录执行：
+
+```bash
+./scripts/verification/run_verification_only.sh \
+  --source-run-dir /data/ours-rp/runs/run_0123 \
+  --source-state-root /data/ours-rp/state \
+  --out-dir /data/ours-rp/verification-runs/run_0123
+```
+
+验证时间自动从源 `input.cir` 读取，不接受命令行覆盖。成功后 scratch work-db 默认删除；排障时可加 `--keep-scratch`。
+
+## 输出
+
+- `input.cir`、`result.ccr`、`report.json`
+- `vrps.csv`、`vaps.csv`
+- `stage-timing.json`、`validation-events.jsonl`
+- `validation-contract.json`、`verification-meta.json`
+- `compare/ccr-state-compare.json`、`compare/ccr-state-compare.md`
+- `stdout.log`、`stderr.log`、`process-time.txt`、`wrapper-timing.json`
+
+通过条件是 compare JSON 中 `stateDigestMatch=true`。`producedAt` 不参与比较。
+
+## 隔离保证
+
+- 不分配 normal run id，不更新 lifecycle、periodic snapshot 计数和 retention。
+- 源 work-db 只用于创建 checkpoint，后续写入只发生在独立 scratch work-db。
+- 源 repo-bytes.db 以只读模式打开。
+- 输出目录必须不存在，防止覆盖旧验证证据。
+
+## 常见失败
+
+- `current state binding`：所选 run 已不是当前 state 对应的最新成功 run，需选择 binding 指向的 run。
+- `differs from current state binding`：源 CIR、CCR 或 contract 已变化，不能继续复核。
+- `blob is missing`：repository view 引用的原始 bytes 不完整，验证不会启动。
+- `did not enable a validation cache`：源 run 不是缓存正确性对比的有效基准。
+- `CCR state digest mismatch`：查看 `compare/` 下 JSON/Markdown，按不匹配状态集合继续排查。
