IaC 面 (infra/) 与控制面 (server/internal/provision) 双产出，落地 doc/04 §4 「节点是牲口」弹性拓扑与 make-before-break 一键更换。 server/internal/provision: - CloudAdapter 适配层 + Registry（首发 vultr 消耗品池 / hetzner 精品池各一）； 厂商凭证仅从 PROVISION_<VENDOR>_* env 注入，不入库不入 git。 - ProvisionService：CreateNode(幂等键重放不重复开机)、DestroyNode(幂等)、 RotateIP(换 IP 不换机 + version bump)、ListProviders。 - Replace 一键更换：先建后拆，新机 up 先于旧机 draining（容量不下降）， replacement_uuid 幂等键 + replacements 表分步记录，崩溃可续跑不重复。 - RotatePool：池内滚动轮换，并发度 1–2。 - cmd/nodectl CLI：create/destroy/rotate-ip/replace/rotate-pool/providers。 - 单测（mock 厂商 API + 内存 Store）：幂等重放、make-before-break 时序断言、 开机失败/探活超时→destroyed+失败计数+告警钩子、崩溃续跑、RotatePool。 infra/: - terraform/：探针机 + 控制面基线模块化（probe / control-plane）+ README， 低频基线进 state，节点不进 Terraform。 - cloud-init/node.yaml.tmpl：节点引导模板（注入一次性 bootstrap token，task #5）。 - identity-isolation.md：身份隔离登记表（doc/06 §2 红线，无任何凭证）。 migrations/000008：nodes 增 provider_instance_id/elastic_ip_id、node_events 增 ip_rotated、provision_idempotency / replacements 表（附加式，不动现网）。 红线：仅面向新厂商池，绝不纳管现网生产 EC2(deploy/ marzban)。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Module: probe
Provisions one overseas reference probe point (doc/04 §1, §4.2).
Probes are low-frequency baseline resources, so they live in Terraform state — unlike data-plane nodes, which are disposable cattle managed by the provision service via vendor APIs (never in Terraform).
What it creates
hcloud_serverrunning the probe agent (installed out-of-band; the probe holds no data-plane secrets and no user data).- A firewall locking inbound to SSH (optionally CIDR-restricted).
Role in the system
Overseas probes cross-check the in-China probe fleet so the scheduler can tell blocked (in-China fails, overseas OK) from machine down (both fail), avoiding false positives before triggering an automatic replacement (doc/04 §4.2).
In-China probe points use serverless / third-party dialing services under a separate isolated identity and are out of Terraform scope — registered in
../../identity-isolation.md.
