-name: homelab-knowledge
-description: Query and maintain the shared homelab-wiki when working on homelab services, infrastructure, architecture, operations, or current service status. Use it to gather existing context before work and to keep durable knowledge synchronized after relevant changes; do not use it for unrelated software work or as a substitute for commit and PR history.
----
-
-# Homelab Knowledge
-
-Use `homelab-wiki` as the shared long-lived knowledge base for people and agents. Search it directly with `rg`; do not introduce a search index, vector database, or generated copy of the wiki.
-
-## Locate the wiki
-
-Resolve the checkout in this order:
-
-1. `$HOMELAB_WIKI_PATH`, when set.
-2. A sibling directory named `homelab-wiki` next to the current repository.
-3. `/home/panxiao81/homelab-wiki` when it exists.
-
-If no checkout is available, report that constraint. Do not silently skip the knowledge step, clone a repository, or create a replacement wiki without the user's authorization.
-
-Before using the wiki, read its `AGENTS.md` completely. For edits, also read `README.md` and `CONTRIBUTING.md` completely and follow any more specific instructions associated with the target page.
-
-## Gather context
-
-At the beginning of a homelab task:
-
-1. Derive search terms from the component name, service aliases, hostnames, Kubernetes resources, configuration keys, error text, and task intent.
-2. Use `rg -n -i` in the wiki to find candidate pages. Prefer several precise searches over reading the whole repository.
-3. Follow the wiki's task index, service index, architecture constraints, source records, and verification conflicts when they are relevant.
-4. Read the closest authoritative pages and their material links before making decisions. Also read the corresponding source repository README or runbook when changing an implementation.
-5. Distinguish documented design, declared configuration, deployment history, live verification, and work currently in progress. Do not present one as another.
-
-For questions about current project or service status, first obtain the maintainer's current-work and ticket context as required by the wiki, unless the conversation already provides that authorization and scope. Reading documentation does not authorize live-system inspection.
-
-Answer read-only questions from the evidence found. Include paths or links that let the user verify important claims, and state when evidence may be stale or conflicting.
-
-## Maintain knowledge after changes
-
-For any code, configuration, infrastructure, or operational change, perform a documentation-impact check before declaring the task complete.
-
-Update the wiki in the same task when the change affects durable knowledge such as:
-
-- service purpose, lifecycle, entry point, authentication, permissions, dependencies, or first-use path;
-- architecture boundaries or accepted constraints;
-- deployment ownership or persistent operating behavior;
-- troubleshooting, recovery, verification, or maintenance procedures;
-- the addition, replacement, or retirement of a service.
-
-Keep one-time progress, implementation narration, and release-by-release history in commits, PRs, or tickets. Do not copy them into the wiki unless they change a durable stage summary. Implementation-specific parameters may remain in the source repository README or runbook when the wiki convention says to link rather than duplicate them.
-
-When editing:
-
-1. Inspect both the source-repository diff and the wiki working tree before writing. Preserve unrelated user changes in both repositories.
-2. Update the page closest to the fact first, then only the navigation, indexes, constraints, or verification records that the wiki rules require.
-3. Preserve evidence metadata. Never advance `last_verified` without performing the stated live verification; ordinary review may update only fields permitted by the wiki.
-4. Link related source commits, PRs, or paths when available. Clearly mark uncommitted sources and unfinished cross-repository synchronization.
-5. Record conflicts rather than resolving them by assumption. Ask before live inspection or before choosing among materially conflicting current-state claims.
-6. Keep credentials, tokens, private keys, Terraform state, secret values, and sensitive command output out of documentation. Never read or copy known sensitive files merely to improve the wiki.
-
-Wiki edits are a separate repository change. Do not commit, push, open a PR, or modify a live system unless the user has authorized that action.
-
-## Verify and report
-
-After editing the wiki, run from its root:
-
-```bash
-python3 scripts/check_docs.py
-git diff --check
-```
-
-If the checker itself changed, also run:
-
-```bash
-python3 -m unittest discover -s tests -v
-```
-
-In the final response, report source-repository changes and wiki changes separately, including validation performed and anything still awaiting verification or cross-repository linkage. If no wiki update was needed, state the concrete reason; do not merely say that documentation was unaffected.

-# Database 模块
-
-Database 是 Ayatori 首批实际产品领域之一。当前已包含 Instance 领域基础、管理凭据连接与
-metadata 观察切片，尚未完成 Database API/controller 和 Tenant 供应链路。
-
-## 当前设计（2026-09-24）
-
-采用 Instance → Database → Tenant 的资源与申请模型；Database 独立存在，支持显式导入、
-Retain 后人工重新绑定与资源侧 Delete。撤销 PostgreSQL ownership registry 及任意 status
-丢失自动恢复所有权的要求。未知同名资源或创建结果不确定时，清楚报告 Conflict 并人工处理。
-
-依据 [ADR-0009](../decisions/0009-database-resource-and-claim.md)，当前合同见
-[系统规格](specification.md)。下面的迁移来源与已存在代码不反向约束新设计。
-registry adapter、专属迁移/测试及 Instance 的 registry 判定现已撤除；Instance 根据完整管理
-能力观察直接判定 Ready。新增 Database 资源、绑定、导入、角色/凭据管理边界与回收链路尚未实现。wiki 同步位置见
-`homelab-wiki/services/postgresql-tenant-operator.md`，跨仓库发布状态由 wiki 的同步记录维护。

-完整设计合同及首批领域模型与测试提取自原 PostgreSQL Tenant Operator：
-
-- 仓库：`git.ddupan.top/panxiao81/postgresql-tenant-operator`
-- source commit：`dae546e58efa1be81e930861c87f7fb13bb12113`
-- 原路径：`internal/domain/instance/`、`docs/domain-instance.md`
-- 迁移日期：2026-09-20
-
-本目录迁入该基线的 specification、architecture、API、领域、部署、安全、开发、迁移与运维
-文档，最初只进行 Ayatori 产品归属、API group、目录和链接适配；2026-09-24 经维护者
-批准的资源/申请分离修订明确替代 registry、自动恢复与原 Retain 合同，其余适用的安全约束保留。
-
-迁移只使用该 commit 中已提交的文件。源仓库
-`feature/instance-extension-observations` 工作树中的 `instance.go` 修改与
-`instance_extensions_test.go` 未进入本切片。
-
-代码被移动到 Ayatori 的 `internal/database/domain/instance`，测试 import 和文档链接相应更新；
-首个后续切片按已批准合同增加 Instance extension observation：观测与当前 target 绑定，进入重新
-验证或删除时失效，且支持判定不授权 Tenant provisioning。已有 Ready 切片曾按原合同加入
-registry 准备决策；这一依赖现已从代码移除，不能把旧运行链路接回模型。
-各层验证边界见 [Instance 领域规格](domain-instance.md)。
-
-## 边界
-
-- 领域层不依赖 Kubernetes types、数据库 driver 或凭据 provider。
-- CredentialReference 只携带管理 Secret 的名称与字段映射，不包含 Secret 内容或 OpenBao path。
-- Instance checkpoint 不是外部事实；实际能力必须由 application/adapter 观察后交给领域对象判断。
-- 当前代码只检查 Instance 供应前置条件，不授予 Tenant 所有权或外部写入权限，也不表示
-  Database API 已经可用。
-
-## 管理凭据与连接切片
-
-`application.InstanceService` 适配自原项目固定基线
-[`internal/instance/service.go`](https://git.ddupan.top/panxiao81/postgresql-tenant-operator/src/commit/dae546e58efa1be81e930861c87f7fb13bb12113/internal/instance/service.go)，
-保留 CredentialReader、Connector、Database 的装配边界及串行操作/释放规则。
-具体连接池完全由 pgxpool v5.11.0 提供，PostgreSQL adapter 不拥有凭据缓存、轮换流程或任意观测回调。
-
-相对源基线有两项按已批准合同作出的必要修改：管理凭据从固定 controller namespace 的
-Kubernetes Secret 直接读取；每轮比较有效用户名、密码，检测到变化即关闭旧连接并重新装配。
-Secret metadata 和无关字段变化不重建连接。观测后再次读取 Secret，中途有效值变化则丢弃结果，
-不把旧连接的成功作为新凭据有效的证据；这不构成跨 Kubernetes/PostgreSQL 的原子事务。
-Instance UID、endpoint 或凭据引用变化也会释放旧连接；Forget/Close 只释放本地资源。
-
-当前通过 `ObserveMetadata` 读取服务器版本和可用扩展，`ObserveVersion` 只是其版本读取便捷入口，
-不能产生完整 CapabilityObservation 或 Ready。
-controller 接入、Secret watch、finalizer 与真实权限检查仍待后续切片；并发 CR 更新
-必须由调用者通过 resourceVersion 校验。应用层沿用源实现的串行处理，本阶段未引入新的调度框架。
-
-运行 `make test-database-integration` 验证真实 API server + 一次性 PostgreSQL；fixture 不接受外部
-DSN，镜像固定摘要，使用随机本机回环端口并在退出时删除测试容器。覆盖缺失/错误凭据、RBAC、
-namespace 边界、有效值轮换、metadata 无关变化、中途轮换、重建/重试、并发读取、Forget/Close
-与 TLS DNS/IP SAN、错误 CA/主机名和禁止明文降级。CI 使用 Pod runner 执行，由 runner 提供
-可用的 Docker，workflow 只做预检、不自行启动 daemon；不依赖 VM。普通 lint 之外还检查
-integration 标签代码。领域单测、真实 API 行为与真实 PostgreSQL 行为分别验收，不以本切片
-替代整个 Instance controller 的集成验收。
-
-## 服务器 metadata 与扩展观测
-
-SQL adapter 通过一条只读语句读取 `pg_catalog.current_setting('server_version')` 和
-`pg_catalog.pg_available_extensions`，避免从已安装列表推断可用列表，且不依赖可修改的
-`search_path`。查询失败丢弃整份结果；成功返回空列表与尚未观察严格区分。
-参考 PostgreSQL 的 [pg_available_extensions](https://www.postgresql.org/docs/18/view-pg-available-extensions.html)
-与 [CREATE EXTENSION](https://www.postgresql.org/docs/18/sql-createextension.html) 合同：可用列表
-表示服务器提供的扩展，不证明管理账号有安装权限，也不保证依赖和其他安装前提满足。
-
-`InstanceService` 保留原有 CredentialReader → Connector → Database 边界，复用同一个
-凭据读取、连接刷新和串行释放流程，不新增连接池封装或任意查询回调。每次重新查询 metadata，
-并在 Secret 有效值回读一致后生成不可变的 `MetadataObservation`，绑定本次 target（含当前
-generation），不绑定建池时的旧 target。结果不包含凭据，扩展集合不与 driver 的可变 slice 共享。
-凭据中途变化、读取失败或查询失败时，返回零值观察并释放连接，不复用旧的扩展列表。
-
-调用方可将 `Target()` 与 `Extensions()` 交给 Instance 的 `ObserveExtensions`；应用调用链
-仍负责同轮次使用，不能持久化或跨轮缓存这份证据。metadata 读取不安装扩展、不初始化 registry、
-不设置 Ready，也不授予 Tenant 写权限。管理权限矩阵及 controller 的
-checkpoint/status/finalizer 链路仍是后续切片。
-
-真实 API server + PostgreSQL 测试验证未安装扩展可被观察、名称保持大小写、search_path 遮蔽
-不改变查询来源、低权限账号读取、权限撤回失败与恢复、Secret 中途变化丢弃扩展结果。
-单元测试补充成功空列表、查询附带部分数据时丢弃、结果与可变 slice 隔离、每轮重新读取和
-generation 变化时的目标绑定；原凭据/TLS/超时/并发测试沿同一 metadata 路径继续运行。
-
-## Registry 撤除
-
-原 `adapter/postgresql/registry`、SQL 迁移、registry 专属集成测试及 tern 依赖已删除；
-未提交的 inspection 实验也已撤除。来源仍可在 Git 历史追溯，没有删除外部 PostgreSQL 对象。
-Instance 不再具有 InitializingRegistry 阶段、RegistryState、准备决策或回读方法；
-首次完整管理能力观察即可完成验证，重验失败则撤销本轮就绪证据。
-
-保留凭据读取与连接刷新、TLS、metadata/扩展观察及其真实后端测试。领域测试覆盖每项能力
-在初次验证和 Ready 重验时失败、依赖恢复、重启后重新取证、错误目标/阶段及删除保护。
-这不等于管理权限探测矩阵或三资源 controller 已实现。

-| 项目 | 内容 |
-| --- | --- |
-| 状态 | API schema 与绑定 controller 已实现；供应、交付与删除清理未接入 |
-| API group/version | `database.ayatori.ddupan.top/v1alpha1` |
-| 最后更新 | 2026-09-25 |
-
-以 [系统规格](specification.md) 与
-[ADR-0009](../decisions/0009-database-resource-and-claim.md) 为准。类型与生成的 CRD 已纳入源码，
-尚未发布为可用 DBaaS。示例可进入绑定协调，但不代表创建对象后会供应数据库或交付凭据。
-
-## 当前 API 切片
-
-Go 类型位于 `api/database/v1alpha1`，CRD 随 `config/crd` 发布；manager 已注册 Scheme 和
-`internal/database/controller` 的绑定 controller。以下字段是本切片的具体实现：
-
-| 资源 | 字段 | 含义 |
-| --- | --- | --- |
-| Database | `spec.instanceRef.name` | 所属集群级 Instance |
-| Database | `spec.database`、`spec.loginRole` | 实际数据库与唯一登录 owner，必填 |
-| Database | `spec.source` | 必填 `Provision` 或 `Import`，不隐式认领 |
-| Database | `spec.credentialRef.mount/path` | Import 必填的已有 KV v2 凭据位置；Provision 禁止指定 |
-| Database | `spec.reclaimPolicy` | Retain 默认或 Delete |
-| Database | `spec.tenantRef.namespace/name/uid` | controller 写入的完整绑定身份，不是允许名单 |
-| Database | `status.instanceUID` | 观察时的 Instance 身份 |
-| Tenant | `spec.provision.instanceRef.name` | 动态申请来源，与 `spec.databaseRef` 互斥且必须二选一 |
-| Tenant | `spec.provision.database/loginRole` | 可省略，语义默认值由 controller 解析，不由 CRD 推导 |
-| Tenant | `spec.databaseRef.name` | 显式申请已有 Database，不额外指定 Instance |
-| Tenant | `spec.extensions`、`spec.secretName` | 扩展集合与同 namespace 的交付目标 |
-| Tenant | `status.databaseRef.name/uid` | 资源侧绑定成功后写入 |
-| Tenant | `status.secretName`、`status.credentialURL` | 交付观察，不包含密码或认证信息 |
-
-三资源均有 status subresource、observedGeneration 和按 type 唯一的 Conditions。
-Instance phase 沿用已批准枚举；Database/Tenant phase 暂不冻结供应子阶段枚举。
-`credentialRef.path` 是 mount 内逻辑路径，不包含 KV v2 的 `data/` 前缀。
-其部署允许范围、实际凭据读取和 URL 安全构造仍由后续 adapter/controller 验证。
-
-示例：[Instance](../../config/samples/database_v1alpha1_postgresqlinstance.yaml)、
-[导入 Database](../../config/samples/database_v1alpha1_postgresqldatabase.yaml)、
-[动态/已有资源申请](../../config/samples/database_v1alpha1_postgresqltenant.yaml)。
-
-当前 schema 验证名称、端口、IP、TLS 枚举、申请互斥、导入凭据要求和绑定 UID 完整性。
-API 接受两个 Tenant 引用同一 Database 不表示允许双重绑定；排他绑定由 controller 协调。
-绑定 controller 解析动态 database/loginRole 的 Tenant 名称默认值；动态资源 CR 名称为
-`tenant-<Tenant UID>`，首次创建即包含资源侧绑定与 finalizer，不带 Tenant ownerReference。
-已有资源必须有当前版本 Ready 观察、匹配的 Instance UID，并处于未绑定的 Available 状态。
-同一 Tenant 的资源侧记录已写入时，允许回读后补齐申请侧，不重新争抢资源。
-
-Tenant 进入 `status.phase=Binding` 后由 CEL 固定申请目标；Database 有实例身份观察或
-绑定后固定实际 database、loginRole、来源和凭据引用，回收策略仍可修改。
-读取绑定判断使用 APIReader，写入依靠 resourceVersion；watch/cache 负责触发协调。
-绑定顺序由 application service 协调，纯资格规则在领域层；Kubernetes adapter 负责快照
-映射、finalizer 和状态呈现。呈现前若资源版本已变化，返回冲突供下一轮重读，不覆盖其他修改。
-双向记录完成后 Tenant 为 Bound，Ready=False/BindingComplete，明确尚未供应或交付。
-生成的 manager RBAC 仅授予绑定所需资源读写，不包含 Secret 读取或后端凭据权限。
-
-当前有 Tenant/Database finalizer 保护，但**删除清理尚未实现**：Tenant 删除报告
-Ready=False/DeletionPending 并保留绑定与 finalizer，Database 的保护也不会被自动移除。
-还未实现删除流程开始后的回收策略固定、Retain 释放、Released 重新开放、外部清理、
-扩展只追加、Secret 默认名称解析与凭据交付。在后续清理协议和真实后端验收完成前，
-不能作为可用 DBaaS 部署，也不能通过强行移除 finalizer 把它视为已完成清理。
-
-## 通用约定
-
-- Instance 与 Database 是 cluster-scoped；Tenant 是 namespaced。
-- Tenant 按名称引用 Database，不提供 Database namespace；Database 绑定记录包含
-  Tenant namespace/name/UID。字段见当前 API 切片；绑定采用下述资源侧先写顺序。
-- 每类资源提供唯一的 Ready Condition、observedGeneration；phase 用于进度展示，
-  不能单独作为写权限或所有权证明。
-- 引用必须区分定位名称与已绑定 UID；同名新对象不继承绑定。
-- controller 管理 status；资源侧管理与回收权限不得随 Tenant editor 权限自动授予。
-- 固定默认值使用 CRD defaulting，跨字段/不可变校验使用 CEL 或 controller；
-  并发更新使用 resourceVersion，不增加 mutating webhook 或跨系统事务。
-- database/role identifier 继续匹配 `^[a-z][a-z0-9_]{0,62}$`。
-- 动态申请的 database/loginRole 省略时继续以 Tenant metadata.name 为语义默认值；
-  显式导入资源使用实际目标，不从新 Tenant 名称重新推导。最终互斥字段须经 API 评审。
-- 投射仍位于 Tenant namespace，ExternalSecret 默认命名沿用
-  `<instanceRef>-<metadata.name>-postgresql`；目标 Secret 可由申请指定，省略时同名。
-  有效 Instance 名称与 Tenant 名称合计不超过 241 字符；完整名称须满足 API 名称校验。
-- 任何 spec/status/错误不得出现密码、Token 或完整秘密响应。
-
-## PostgreSQLInstance
-
-保留管理入口字段：
-
-| JSON path | 类型 | 必填/默认 | 合同 |
-| --- | --- | --- | --- |
-| `spec.endpoint.host` | string | 必填 | PostgreSQL DNS 名；必须被服务端证书 DNS SAN 覆盖 |
-| `spec.endpoint.hostaddr` | string | 必填 | 单个 IPv4/IPv6；必须被服务端证书 IP SAN 覆盖 |
-| `spec.endpoint.port` | int32 | `5432` | 1–65535 |
-| `spec.endpoint.database` | string | `postgres` | 管理连接 database；合法 PostgreSQL identifier |
-| `spec.endpoint.sslMode` | enum | `verify-full` | `disable`、`require`、`verify-ca`、`verify-full` |
-| `spec.adminCredentialRef.name` | string | 必填 | controller namespace 内的管理 Secret 名称 |
-| `spec.adminCredentialRef.usernameKey` | string | `username` | Secret data 中的键名 |
-| `spec.adminCredentialRef.passwordKey` | string | `password` | Secret data 中的键名 |
-
-
-管理 Secret 固定在 controller namespace，不接受 namespace 或 Bao path。
-管理员维护其 ExternalSecret，controller 只读；有效用户名/密码变化时重验连接。
-endpoint 变化使旧观察失效，不迁移旧服务器的数据，不自动接管旧 UID 的资源。
-
-Status 保留 observedGeneration、postgresqlVersion 和 conditions；
-phase 为 Pending、Validating、Ready、Deleting，移除 InitializingRegistry。
-Ready 要求连接、metadata 与所需管理权限，不要求 registry。
-实例实际可用扩展来自查询，不提供 allowedExtensions 配置。
-
-开始受管时保存 finalizer；删除时阻止新供应，并检查 Database（含 Released）及未绑定
-Tenant 引用。无引用才解除，不级联删除资源；查询失败不能视为无引用。
-
-## Database 资源（工作 Kind：PostgreSQLDatabase）
-
-v1alpha1 以一个 database、一个兼任 owner 的 login role 及其应用凭据作为 Database 的
-生命周期边界；不提供多账号字段或独立 Role/Credential CRD。多账号需求留待后续 API 版本。
-此决定不改变导入只读验证和显式管理授权的要求。
-
-Database 是平台管理的集群级资源，不归属于应用 namespace，也不需要资源专用 namespace。
-普通申请者通过 Tenant 申请使用，不能自行修改 Database 回收策略或将 Released 资源重新开放；
-这些资源管理操作由平台管理员授权。controller 的绑定协调权限与用户申请权限分别配置。
-
-以下是行为合同，具体 schema 见当前 API 切片与生成的 CRD；后端行为尚未实现：
-
-| 内容 | 合同 |
-| --- | --- |
-| `instanceRef` | Database 自身必填；定位来源并记录绑定的 Instance UID，不依赖 Tenant 补齐 |
-| 外部目标 | 实际 database 名称及已确认的管理范围；操作开始后不可隐式改目标 |
-| 来源 | 区分动态供应与管理员显式导入；不能从同名存在推断导入授权 |
-| 绑定 | 至多一个 Tenant，含 namespace/name/UID；Released 保留旧身份；无允许绑定名单 |
-| 回收策略 | 资源侧 Retain（默认）或显式 Delete；普通 Tenant editor 不得扩大授权 |
-| 观察与进度 | 实际目标、当前阶段、条件和安全诊断，不保存秘密 |
-
-概念生命周期包含供应/验证、可绑定、已绑定、Released 和删除；最终 phase 枚举待协议评审。
-Released 不自动变成可绑定。Database 不以 Tenant 为 GC owner；使用中的资源受删除保护。
-
-导入的初始检查只读；存在不等于 Ready。未绑定且可用的资源允许 Tenant 显式申请，
-不要求管理员逐 Tenant 授权；已占用或 Released 的资源不能直接绑定。
-默认保留不隐含密码、owner、授权或删除的变更许可。
-
-## PostgreSQLTenant
-
-保留用户申请与交付职责：
-
-- 动态申请描述 Instance、所需数据库/登录角色、扩展与目标 Secret；
-  或显式引用管理员已登记的 Database。后者从 Database 获取 Instance，不重复指定来源；
-  两条路径互斥，具体 schema 在 API 切片固定。
-- 绑定前固定有效需求，绑定/开始供应后不能通过改引用或名称迁移资源。
-- extensions 成功后只允许追加，不自动卸载。
-- status 展示绑定 Database 身份、Ready、交付 Secret 引用及不含认证信息的 OpenBao URL。
-- Tenant 删除释放申请，按照 Database 的回收策略处理，不独立持有最终删除授权。
-
-旧 Tenant `spec.deletionPolicy` 不再作为最终资源回收策略；旧字段表、供应 phase 枚举及
-仅按 Tenant namespace/name 派生凭据路径的规则不再是实现合同。已有代码没有兼容负担，
-不保留两套相互覆盖的策略字段。
-
-## 已确认的绑定顺序
-
-1. 动态申请按 Tenant UID 确定 Database 名称并创建记录；已有资源申请使用指定的 Database，
-   检查资源未绑定且可用，不增加反向授权名单。动态创建重试遇到同名记录时需核对身份与目标。
-2. 使用 resourceVersion 并发控制，先在 Database 记录 Tenant namespace/name/UID。
-   已绑定其他 Tenant 时报告 Conflict，不抢占；版本冲突后重新读取、重新判断。
-3. 在 Tenant status 记录 Database name/UID。若上一步成功、本步失败，后续 reconcile
-   核对身份后补齐，不回滚已经成功的资源侧绑定。
-4. 双向记录一致才允许动态供应或凭据交付；实际数据库与凭据验证通过后才可 Ready。
-
-此顺序借鉴 PV/PVC 的资源侧先写模式，行为依据见
-[系统规格](specification.md#5-动态供应与排他绑定)。Retain 释放时保留旧绑定身份并进入
-Released，不自动清空后重新分配。API 记录部分写入由 reconcile 重试；外部创建结果
-无法确认时仍报告 Conflict，交给人工，不新增事务队列或 registry。
-
-## 绑定协议剩余评审要求
-
-实现前必须明确：
-
-1. 引用字段的最终格式，以及落实管理员资源管理、controller 协调与普通申请权限的 RBAC 规则。
-2. 绑定记录的最终字段及校验规则，落实上述写入顺序与恢复行为。
-3. Tenant UID 变化、对象删除、Released 旧引用与管理员重新授权的判断。
-4. 同一物理数据库重复登记的冲突处理；列表查询不是原子认领。
-5. 已有凭据关联字段、旧访问处置与投射清理顺序；动态凭据路径已确定按 Database UID 定位。
-6. Tenant/Database finalizer 配合；回收策略默认 Retain，删除流程前可改，进入后固定。
-
-资源管理者设置 Delete 即表示删除授权，不增加额外审批字段。导入显式关联已有凭据；
-Released 不自动改密，管理员处理旧访问后才重新开放。Tenant 不得自选任意 OpenBao 路径。
-
-该协议使用 Kubernetes API 持久化，不为它新增 PostgreSQL registry。
-未完成一致绑定不得供应或交付；外部创建结果不确定按 Conflict 人工处理。
-
-## Conditions
-
-每类资源至少提供唯一的 Ready；同类型 Condition 不重复，维护 lastTransitionTime 与
-observedGeneration。最低安全错误分类见 [系统规格](specification.md#10-conditions-与可观测性)。
-
-Conflict 必须说明目标、步骤、已确认与不确定部分及人工核实建议；不能建议清空 status、
-伪造 Ready 或改密码绕过。可恢复依赖故障退避重试，冲突不忙循环。
-具体 Reason 在 API 切片固定，Released 不得误报为可立即交付。
-
-## 实现验收
-
-CRD defaulting、CEL、status subresource、resourceVersion、并发绑定、重启与依赖 watch
-使用真实 API server 验证；ownerReference/namespace 删除的实际 GC 使用测试集群。
-类型、CRD、sample 和 contract tests 必须一起对齐，不以 fake client 替代 API 语义。

-本页解释 [系统规格](specification.md) 的组件边界；资源与申请分离的依据见
-[ADR-0009](../decisions/0009-database-resource-and-claim.md)。设计已确认，运行链路尚未完成。

-## 资源与后端
-
-```text
-Kubernetes API
-  Instance ──引用── Database ──排他绑定── Tenant
-                         |
-              Ayatori Database controllers
-                   |          |          |
-              PostgreSQL   OpenBao   ExternalSecret

-                                        ESO → Secret
-```
-
-Kubernetes 保存声明、绑定与操作进度；PostgreSQL 保存实际数据库状态；OpenBao 保存应用凭据。
-不在 PostgreSQL 中再建立管理 registry。Instance 是管理入口而非 CSI 协议实现，adapter 是薄访问层。
-
-Instance 验证当前目标的管理能力，不供应 Tenant 数据库，不因 registry 缺失初始化任何 schema。
-Database 用例负责独立资源的供应、显式导入、保留与回收；Tenant 用例负责申请、绑定与凭据交付。
-这是用例职责，不要求为每一步新增一个 controller 或通用控制循环。
-
-## 协调与恢复
-
-通过 Kubernetes API 的 resourceVersion 保护并发更新，watch 推动依赖恢复；外部操作前保存
-资源与意图，执行后观察并记录结果。数据库实际操作仍须处理后端竞态，列表检查不是唯一约束。
-
-可靠确认的步骤允许幂等继续；外部创建与进度写入之间的失败若导致归属不确定，则停止写入并
-报告 Conflict。不创建第二套所有权存储，不承诺跨系统事务或任意 status 丢失自动认领。
-错误必须提供人工可用的步骤、资源与结果确定性信息，但不泄漏秘密。
-
-## 绑定、导入与回收
-
-Database 独立于 Tenant 存在，不能以会导致级联删除的 ownerReference 连接两者。
-Instance 删除检查 Database 引用，包括 Released 资源，不直接清理数据库。
-
-动态供应和管理员导入使用同一种资源记录。导入验证初始只读；未知同名数据库仍为冲突。
-Retain 保留资源及旧绑定身份；重新绑定必须经过人工数据和访问权限处置，不自动分配。
-Delete 由资源侧明确授权，在 finalizer 保护下按管理范围清理并逐步回读。
-
-角色、凭据与投射的具体管理字段和清理顺序仍需 API 评审，不能用 PV 类比代替数据库权限设计。
-
-## 保持的访问边界
-
-管理 Secret 固定在 controller namespace，管理员维护其 ExternalSecret；controller 只读。
-有效值变化刷新管理连接，不直接访问 Bao 获取管理凭据，不自行实现连接池。
-应用凭据写 OpenBao，由 ESO 投射；controller 不直接写明文 Secret。
-TLS、DNS/IP SAN、七键凭据输出和最小权限合同继续适用。

-# 部署与配置
-
-> 本页迁入作为 Database 模块的目标部署合同。Ayatori manager flags、manifests 与发布装配尚未
-> 实现；当前行为以修订后的系统规格为准，本页不能直接用于部署。
-
-| 项目 | 内容 |
-| --- | --- |
-| 状态 | Review |
-| 环境 | homelab Kubernetes + 外部 PostgreSQL/OpenBao |
-| 最后更新 | 2026-09-24 |
-
-本文定义 v1alpha1 的运行依赖、启动顺序和部署级配置。当前 manifests 尚未实现这些
-配置，示例是后续实现合同，不可直接用于现有脚手架。
-
-## 依赖与顺序
-
-1. 准备 PostgreSQL VM、持久盘、备份和网络入口。
-2. 用 OpenBao PKI 签发 PostgreSQL server 证书，包含 Instance `host` 的 DNS SAN 与
-   `hostaddr` 的 IP SAN；配置 PostgreSQL 强制 TLS。
-3. 创建 PostgreSQL controller 管理 role 和管理 database 连接权限。
-4. 在 OpenBao KV v2 写入管理 role 凭据。
-5. 配置 OpenBao Kubernetes auth、controller policy 和面向 ESO 的读取 policy。
-6. 安装 ESO，配置独立的管理凭据同步身份和租户凭据读取身份。管理员在 controller
-   namespace 创建管理 ExternalSecret，确认管理 Secret 已同步；另创建供租户使用的
-   `ClusterSecretStore`。
-7. 创建公开 CA bundle ConfigMap，并挂载到 controller 和需要直接验证数据库的应用。
-8. 部署 controller，再创建 Instance；等待 Ready 后才创建 Tenant。
-
-任何一步都不得把真实密码、Token、kubeconfig 或 CA 私钥提交进 Git。
-
-## Controller 配置合同
-
-以下是尚待实现的部署配置合同，凭据定位随三资源 API 继续细化。controller 使用这些 CLI flags。
-必填项缺失、路径无效或 duration 不为正数时，进程必须在启动 manager 前失败；
-不得等到 reconcile 时才逐个资源报告配置错误。
-
-| CLI flag | 必填/默认 | 说明 |
-| --- | --- | --- |
-| `--openbao-address` | 必填 | controller 可访问的 OpenBao API address |
-| `--openbao-consumer-address` | 默认同 `--openbao-address` | 写入 Tenant status，必须能被预期外部消费者解析 |
-| `--openbao-auth-mount` | `kubernetes` | Kubernetes auth mount 名称 |
-| `--openbao-auth-role` | 必填 | controller ServiceAccount 对应 role |
-| `--openbao-kv-mount` | `kv` | KV v2 mount；开发可显式用 `secret` |
-| `--openbao-service-account-token-path` | `/var/run/secrets/kubernetes.io/serviceaccount/token` | Kubernetes auth 使用的投射 token 文件 |
-| `--openbao-tenant-base-path` | 默认 `postgresql-tenants` | controller 专属 mount-relative 前缀 |
-| `--external-secret-store-name` | 必填 | controller 创建的 ExternalSecret 固定引用 |
-| `--postgresql-ca-bundle-path` | PostgreSQL TLS 模式必填 | 只读 PEM trust bundle，不含私钥 |
-| `--reconcile-timeout` | `30s` | 单轮 reconcile 中外部操作的总期限，必须大于零 |
-
-address 必须是绝对 `http` 或 `https` URL，不允许 userinfo、query 或 fragment，末尾 `/`
-在规范化后移除。mount、auth mount 和 base path 都使用 mount-relative path 语义，不以
-`/` 开头，不含空段、`.` 或 `..`；base path 还不得编码 KV v2 的 `data`/`metadata`
-API 层。生产环境的 `--openbao-address` 必须使用 HTTPS；HTTP 只用于明确的开发 fixture。
-
-Tenant 不能选择任意凭据路径。凭据必须能随 Database 保留并安全交付给被授权的新 Tenant；
-原 `<base-path>/<namespace>/<metadata.name>` 定位规则不再直接作为新 API 合同。
-稳定位置与导入关联方式待 API 评审；consumer URL 仍使用无认证信息的 KV v2 API URL。
-
-base path 必须是合法 mount-relative path，不以 `/` 开头且不包含空段、`.`、`..`、
-`data`/`metadata` API 层。ExternalSecret 固定命名为
-`<instanceRef>-<metadata.name>-postgresql`；目标 Secret 可由 Tenant 指定，但名称必须
-满足 Kubernetes Secret 名称校验，不限制命名内容，默认与 ExternalSecret 同名。
-
-配置变化不得隐式迁移既有凭据。修改 KV mount/base path 或 consumer address 前必须
-停止 controller、评估现有 Database 与绑定，并走明确迁移。资源记录应能定位原凭据，
-不能根据新部署参数静默切换；不再使用 registry 保存安装身份。
-
-## PostgreSQL 管理 role
-
-生产部署禁止使用 superuser。管理 role 至少需要：
-
-- 连接管理 database、读取必要 catalog；
-- 创建/修改受管 login role；
-- 创建 database 并指定 owner；
-- 撤销 `PUBLIC` CONNECT、授予租户 role CONNECT；
-- 连接租户 database 并创建实例实际支持、租户申请的 extension；
-- `Delete` 时禁止连接、终止目标 database session、删除已验证归属的 database/role。
-
-部分 PostgreSQL 操作天然要求较高权限，尤其终止其他 session 和安装某些 extension。
-应优先使用 PostgreSQL 预定义角色、受控 SECURITY DEFINER 管理函数或限定数据库的
-授权；任何不得不使用 superuser 的 extension 都必须按实例单独记录，不得扩大默认
-controller 权限。最终可执行 SQL grant 将随 PostgreSQL adapter 集成测试固化。
-
-## OpenBao 与 ESO
-
-controller policy 仅允许在固定 tenant base path 下 create/read/update/delete KV v2
-data 和 metadata，Delete 必须能永久删除全部版本及 metadata；不读取管理凭据路径。
-
-管理凭据由管理员维护的 ExternalSecret 同步到 controller namespace；其 ESO 身份
-只读对应管理路径，不能供 Tenant 使用。租户 ESO 身份只读 tenant base path，不得
-读取 PostgreSQL 管理凭据。controller 不创建或修改管理 ExternalSecret／Secret。
-`ClusterSecretStore` 由平台管理员创建，controller 只引用，不创建或修改 Store。
-controller 创建的 ExternalSecret 与 Tenant 同 namespace；其 ownerReference 和 Retain 时的
-保留/清理须与凭据交付协议一起确定，不能把投射关系等同于 Database 的 GC 关系。目标
-Secret 包含固定七键：`username`、`password`、`database`、`host`、`hostaddr`、`port`、
-`sslmode`。
-
-## Kubernetes RBAC
-
-- controller 按用例读/写 Instance、Database、Tenant 及其 status/finalizer 和 Event。
-- Database 不设置随 Tenant 级联删除的 ownerReference；导入、预留、回收和重新绑定授权限管理员。
-- controller 可在 Tenant namespace 创建、读取、更新、删除 ExternalSecret，并只读检查
-  对应 Secret 是否完成投射。
-- namespace 用户可以管理本 namespace Tenant，但不能管理 Instance、Store、controller
-  配置或其他 namespace 的 ExternalSecret。
-- controller 只在自身 namespace 读取所引用管理 Secret 的 data，不获得跨 namespace
-  的管理 Secret 读取权限。Instance 不允许自选 Secret namespace。
-- 对应用目标 Secret，controller 无需读取 data；验证登录使用从 OpenBao 读取的应用
-  凭据，只检查 Secret 存在性和 ESO 状态。
-
-## 升级与回滚
-
-v1alpha1 尚不承诺跨版本转换。升级前备份 CR/绑定、PostgreSQL 数据与 OpenBao，
-先在隔离 Kind 环境运行 E2E。禁止在同一组 CR 上同时运行两个 controller 版本。若新版本
-在执行任何破坏性迁移前失败，可回滚镜像；涉及 API/storage 或凭据定位迁移时，
-必须先写独立升级规格和回滚步骤。
-
-## 上线验证
-
-```text
-PostgreSQL TLS 与备份验证
-  -> OpenBao auth/policy 验证
-  -> ClusterSecretStore Ready
-  -> controller Ready/leader elected
-  -> Instance Ready
-  -> 测试 Tenant Ready
-  -> DNS host 与 IP hostaddr 分别登录
-  -> 删除测试 Tenant 并验证所选策略
-```
-
-生产 homelab 上线前还必须完成 [`security.md`](security.md) 的权限检查和
-[`operations.md`](operations.md) 的备份/逃生检查。

-# 开发与测试环境
-
-> 本页迁入作为 Database 模块的测试分层与 fixture 合同。旧项目的 Make target、devcontainer
-> 和脚手架版本尚未适配 Ayatori；实现时应复用 Ayatori 现有工具链，并保持这里定义的测试边界。
-
-## 当前设计验收（2026-09-24）
-
-[ADR-0009](../decisions/0009-database-resource-and-claim.md) 将资源生命周期从 Tenant 中分离。
-新增验收矩阵见 [系统规格](specification.md#11-验收)。registry 实现、专属测试与迁移依赖已撤除，不继续 schema 审计或自动所有权恢复切片。
-
-| 层次 | 本次设计要求 |
-| --- | --- |
-| 纯领域 | Instance 无 registry 就绪判定、排他绑定、Released 不自动复用、管理范围与冲突规则 |
-| envtest | 三资源 schema/status、RBAC、resourceVersion 并发、绑定单边更新/重启、依赖 watch、finalizer |
-| 真实 PostgreSQL/OpenBao | 同名不修改、显式导入只读验证、创建不确定报冲突、可靠步骤幂等、Delete 故障重试 |
-| 测试集群 | Tenant/namespace 删除不 GC Database、ESO 交付/释放、人工重新绑定前的旧访问处置 |
-
-需故障注入外部成功而 API 写入失败、后端响应丢失、双 Tenant 竞争、同名新 UID、依赖稍后出现、
-Instance 删除与 Released 引用。冲突必须给出可操作而不泄密的诊断；不要求自动认领不确定结果。
-envtest 不运行 GC 或 ESO；这些行为必须由测试集群验证。
-三资源 API 类型与 CRD 已实现，`make test` 包含真实 API server 验证：作用域、
-静态默认值、非法声明、status 写入隔离、Condition 唯一性、resourceVersion 冲突与绑定记录回读。
-另有绑定 controller 的真实 API server 测试：动态记录幂等、资源侧写入后故障注入、
-新 reconciler 回读补齐、双 Tenant 竞争、Released/旧 UID 拒绝、目标固定、陈旧观察、
-删除期间 finalizer 保留。实际 manager 在生成的 RBAC 角色下通过 watch/cache 处理依赖
-稍后出现，绑定角色不具备 Secret 读取权限。没有 PostgreSQL/OpenBao 写入；后端 Ready
-在测试中由 fixture 提供，不能把它当成完整 Instance/Database 观察验证。
-
-Retain 释放和 Delete 清理仍未实现，当前删除会保持 DeletionPending 与 finalizer。
-真实后端供应、凭据交付与上述完整删除矩阵仍待后续切片验收。
-
-绑定规则另有不依赖 Kubernetes 的单元测试；service 测试只验证操作顺序、失败停止与最终
-身份回读，不模拟 API server。原真实 API controller 测试覆盖完整分层调用，另验证 service
-返回后发生并发修改时，资源呈现拒绝过期结果，重试完成绑定且保留其他字段。
-
-## Ayatori 已接入的凭据与 metadata 切片测试
-
-本节命令已在 Ayatori 接入；以下历史 Compose/Kind 操作仍属于迁入的目标合同。
-
-```sh
-make test
-make lint
-make lint-database-integration
-make test-database-integration
-```
-
-最后一项要求本机 Docker 可用。它启动 envtest 的真实 API server/etcd 和固定镜像摘要的临时
-PostgreSQL 容器，随机绑定回环端口，不读取 kubeconfig，也不接受指向现有数据库的 DSN。
-每个凭据场景使用独立环境；测试清理仅关闭自己的进程和按确切 ID 删除自己的容器。
-TLS 测试在临时目录生成一次性证书与私钥，不使用生产 CA。
-
-当前覆盖固定 namespace 的 Secret 读取与 RBAC、缺失/无效凭据恢复、有效凭据变化后的重连、
-无关字段更新不重连、中途轮换时丢弃观察、会话重建、并发读取、本地连接释放和 TLS 验证。
-快速测试、lint 和 Database 集成测试均使用 Pod runner。按维护者于 2026-09-21 更新的接口
-约定，runner 提供默认可用的 Docker；workflow 通过 `docker version` 和 `docker info` 预检，
-不自行启动 daemon、不强制 storage driver 或覆盖 Docker endpoint。该约定的 CI 验收依赖
-runner 后端修复上线，不能从本地测试通过推断远端已经可用。
-fixture 启动失败会保留退出错误与 stderr，并遮蔽测试密码，
-以区分缺少命令、daemon 不可达、权限和镜像拉取失败。
-
-metadata 测试验证版本与可用扩展的只读查询，包括未安装扩展、大小写保持、search_path 遮蔽、
-低权限账号读取、catalog 访问被撤回后的失败与恢复，以及凭据中途变化时同时丢弃版本和扩展。
-权限撤回只修改每个场景自建 PostgreSQL 容器的 ACL；不连接现有服务。
-可用列表不等于安装权限，这些检查不替代后续的完整管理权限矩阵或 Instance Ready 验收。
-
-Instance 领域测试不再提供 registry 状态，初次验证与 Ready 重验分别覆盖所有管理检查项的
-未观察、不可用、认证失败、权限不足及未知值，并验证依赖恢复；完整管理观察可直接 Ready。
-
-PostgreSQL adapter 测试不包含 controller、Secret watch、status/finalizer 事件链、权限探测矩阵、ESO 或 Tenant 供应。
-CRD 基础语义由前述 API 测试覆盖；版本查询成功不意味着 Instance Ready。
-
-本项目同时依赖 Kubernetes API、PostgreSQL、OpenBao 和 ESO。日常开发不连接 homelab
-中的真实服务：Kubernetes 使用 envtest 或一次性 Kind，另外两个依赖使用一次性
-容器。这样既避免污染真实数据，也能把启动顺序固化为命令。
-
-## 是否需要开发 VM
-
-默认不需要。仓库的 devcontainer 使用独立 Docker-in-Docker daemon，Go 工具链、
-Kind 节点和依赖容器都与宿主机环境隔离。宿主机只需要能够运行支持 privileged
-container 的 Docker/Dev Container 环境。
-
-只有以下情况才建议增加一台可随时重建的开发 VM：
-
-- 宿主机不允许 privileged devcontainer；
-- 无法安全使用 Docker socket 或 Docker-in-Docker；
-- 本机地址段与 Kind/Docker 网络持续冲突；
-- 需要长期运行、接近 homelab 网络和 TLS 配置的验收环境。
-
-即使使用 VM，也应在 VM 内继续执行本文相同的容器化流程；不要把 VM 配置成第二套
-手工维护的开发环境。
-
-## 环境分层
-
-| 层次 | Kubernetes | PostgreSQL / OpenBao | 用途 |
-| --- | --- | --- | --- |
-| 单元测试 | fake client | fake client | SQL 计划、状态转换和错误分类 |
-| controller 集成测试 | envtest | fake adapter | CRD、watch、status、finalizer、ExternalSecret 对象 |
-| adapter 集成测试 | 不需要 | Docker Compose | 真实协议、权限和幂等行为 |
-| E2E | 一次性 Kind + ESO | Kind 内测试实例 | 凭据投射、TLS、完整网络和删除路径 |
-
-envtest 只启动 API server 和 etcd，没有 kubelet、scheduler、ESO 或 controller-manager，
-因此不能用它验证 Deployment、Pod 调度或 Service 网络。此类行为必须留给 Kind
-E2E。
-
-## 首次准备
-
-推荐用支持 Dev Containers 的编辑器打开仓库。devcontainer 会提供 Go、Docker、
-Kubebuilder、Kind 和 kubectl。脚本固定 Kubebuilder 4.15.0、Kind 0.33.0 和
-kubectl 1.36.0，与当前脚手架和 Kubernetes Go module 对齐。容器启动后先确认：
-
-```sh
-go version
-docker info
-kubebuilder version
-kind version
-kubectl version --client
-```
-
-不要在仓库中保存真实 OpenBao Token、数据库密码或 kubeconfig。Compose 中的
-`postgres-dev-only` 和 `dev-only-root-token` 是仅绑定回环地址、随容器销毁的公开
-测试值，不得复制到其他环境。
-
-## 日常开发的正确顺序
-
-### 1. 生成并验证纯 Go/Kubernetes 部分
-
-```sh
-make manifests generate
-make test
-make lint
-```
-
-`make test` 会下载与 `go.mod` 中 Kubernetes minor 版本匹配的 envtest 二进制，
-启动临时 API server/etcd，测试结束后自动关闭。
-
-规格实现后，快速测试必须覆盖默认值/校验、Condition `observedGeneration`、三资源的
-状态与绑定、不可变字段、extension 只追加、冲突和外部错误分类。envtest 只断言 controller 创建了正确
-的 ExternalSecret；它不能证明 ESO 已生成 Secret。
-
-### 2. 启动 PostgreSQL/OpenBao adapter 依赖
-
-只有开发 PostgreSQL/OpenBao adapter 或完整 reconcile 时才需要：
-
-```sh
-make dev-up
-make dev-smoke
-```
-
-启动顺序由 Compose healthcheck 保证：
-
-1. 创建独立 Compose 网络；
-2. 启动 PostgreSQL 和 OpenBao；
-3. 等待 PostgreSQL `pg_isready` 成功；
-4. 等待 OpenBao `bao status` 成功；
-5. smoke test 执行 `SELECT 1`；
-6. smoke test 在 OpenBao dev server 默认的 `secret/` KV v2 mount 写入并读回测试管理
-   凭据。
-
-本机进程使用以下端点：
-
-```text
-PostgreSQL: postgresql://postgres:[email protected]:15432/postgres
-OpenBao:    http://127.0.0.1:18200
-Token:      dev-only-root-token
-```
-
-若端口冲突，可以只对当前命令覆盖：
-
-```sh
-POSTGRES_DEV_PORT=25432 OPENBAO_DEV_PORT=28200 make dev-up
-```
-
-后续执行 `dev-smoke` 和 controller 时必须使用相同端口变量。
-
-Compose 使用明文 PostgreSQL/OpenBao dev 模式，不覆盖生产 TLS 合同。DNS SAN、IP SAN、
-Kubernetes auth、最小 policy 和 ESO 必须在 Kind E2E fixture 中验证。
-
-### 3. 运行针对临时依赖的测试或 controller
-
-adapter 集成测试通过独立 Make target 执行，不默认塞进快速单元测试：
-
-```sh
-make test-integration
-```
-
-该 target 会启动一次性 Compose 依赖，并通过 `POSTGRES_TEST_DSN` 把测试指向开发
-PostgreSQL。这是旧环境设计，不是当前 Ayatori 入口；当前 fixture 不接受外部 DSN，
-使用本页前部的 `make test-database-integration`，禁止把测试指向真实 homelab database。
-
-Gitea Actions 的 job 本身运行在 Docker container 中，不能通过 `127.0.0.1` 访问
-Docker host 上发布的 Compose 端口。CI 会暂时将 job container 加入 Compose 网络，
-并通过 `postgres:5432` 运行集成测试；清理前先断开该网络，才能删除 Compose
-network。本机执行仍使用默认的 `127.0.0.1:15432`。
-
-本机运行 controller 时，先确认当前 kubeconfig 指向专用 Kind，而不是真实 homelab：
-
-```sh
-kubectl config current-context
-make setup-test-e2e
-kubectl config current-context
-make install
-make run
-```
-
-此时 controller 运行在开发容器内，可以直接访问上面的回环端口。若要验证 Tenant
-Ready，专用 Kind 还必须安装 ESO、创建测试 ClusterSecretStore，并让 Kind workload
-能够访问测试 OpenBao。不要把包含
-`127.0.0.1` 端点的样例部署到 Kind 内；Pod 中的回环地址只指向 Pod 自身。
-
-### 4. 清理
-
-```sh
-make dev-down
-make cleanup-test-e2e
-```
-
-`dev-down` 会删除 Compose volume；所有数据库和 OpenBao dev 数据都应视为一次性。
-
-## E2E 顺序
-
-CI 的 E2E 与本机 `make run` 不同：controller 会作为 Pod 运行在 Kind 中。因此完整
-E2E fixture 必须把测试 PostgreSQL、OpenBao 和 ESO 部署进 Kind，并等待依赖 Ready 后
-再创建 `PostgreSQLInstance` 和 `PostgreSQLTenant`：
-
-```text
-创建 Kind
-  -> 安装 CRD
-  -> 部署 PostgreSQL/OpenBao fixture，签发含 DNS/IP SAN 的测试证书
-  -> 安装 ESO，配置 OpenBao auth/policy 和 ClusterSecretStore
-  -> 等待依赖 Ready 并写入测试管理凭据
-  -> 构建并加载 controller image
-  -> 部署 controller
-  -> 创建 Instance
-  -> 等待 Instance Ready
-  -> 创建 Tenant
-  -> 等待 Tenant Ready
-  -> 验证 Database 绑定、PostgreSQL catalog、OpenBao KV、ExternalSecret 和 Secret
-  -> 分别使用 DNS host 与 IP hostaddr 登录
-  -> 删除 Tenant 并分别验证 Retain 与 Delete（含故障点重试）
-  -> 删除 Kind
-```
-
-以上 Compose/Kind 流程来自旧项目的环境设计，不是 Ayatori 已实现的运行状态。
-Ayatori 尚未完成 Instance/Database/Tenant controller 链路；当前可执行的切片命令以本页
-前部为准，不能从旧脚手架或 adapter 测试推断完整生命周期已经通过。
-
-## 测试数据与泄漏检查
-
-- 只使用显眼的固定 canary 测试密码，测试后扫描日志、Event、Condition、metrics 和
-  CR dump，出现 canary 即失败。
-- 每个写入阶段注入中断：已确认步骤继续且密码不变；结果不确定则停止并明确报告 Conflict。
-- 缺少绑定/进度记录时不得凭同名外部对象恢复所有权；过期 phase 不得绕过实际观察。
-- 为未知同名 database、role、Bao record 和伪造 COMMENT 分别构造 Conflict。
-- Delete 在每个外部删除步骤失败后重试，确认未误删非当前 UID 资源。
-- 迁移测试按 [`migration.md`](migration.md) 完整执行，不以单纯 `pg_restore` 成功代替
-  应用读写和回滚验证。
-
-## 故障排查
-
-查看依赖状态与日志：
-
-```sh
-docker compose -f hack/dev/compose.yaml ps
-docker compose -f hack/dev/compose.yaml logs postgres openbao
-```
-
-如果 envtest 报端口监听失败，通常是当前执行环境禁止监听回环端口，而非 controller
-失败；在 devcontainer 或允许本机监听的 runner 中执行。若 Kind 无法创建，先运行
-`docker info`，确认当前用户可以访问 devcontainer 内的 Docker daemon。

-
-## 行为
-
-- Reconstitute 校验 definition，重建 checkpoint，丢弃旧 evidence。
-- BeginValidation 清空能力证据并进入 Validating。
-- AssessManagement/AssessReadiness 根据本轮完整观察判断 Ready 或安全失败；
-  方法的具体合并方式在实现重构时决定，不保留无意义的中间初始化阶段。
-- CheckExtensions 判定请求集合，不能单独授权供应。
-- RequireProvisioningReady 检查本轮能力与删除状态；不授予 Database 所有权。
-- BeginDeletion 禁止新供应，不执行外部删除。
-- Snapshot 返回值副本，不序列化 evidence 或秘密。
-
-撤销 PlanRegistryPreparation、AssessRegistryResult、RegistryPreparationResult、
-RegistryState 与 InitializingRegistry 的设计需求。不能用始终返回 Usable 的兼容层绕过旧逻辑。
-
-## 应用与连接边界
-
-管理凭据来自 controller namespace 的 Secret；管理员维护 ExternalSecret，ESO 同步。
-Instance 不直接访问 Bao。有效用户名/密码变化时应用层释放旧连接、用新值装配并重验；
-metadata/无关字段变化不重建。采集途中有效值变化必须丢弃观察，不因 generation 没变而复用。
-controller 不修改 PostgreSQL 密码、管理 Secret 或 Bao 管理凭据。
-
-InspectManagement 是观察能力，不包含 schema 初始化/迁移。只读 metadata 查询仍不足以
-证明管理权限；真实权限矩阵由 adapter 定义和测试。连接复用由 pgxpool 提供，不自建池。
-已可用管理凭据下，Bao/ESO 当前故障不单独撤销 Instance Ready。
-
-## 状态与删除
-
-```text
-Pending → Validating → Ready
-Ready → Validating（配置/凭据变更或能力失效）
-任意阶段 → Deleting
-```
-
-应用层保存意图、获取观察、领域判定、按 resourceVersion 保存结果；
-保存冲突重新装载，不能覆盖较新配置。Instance 观察本身不创建外部资源，
-初始 status 缺失可重新探测，不由此推出 Database 所有权可自动重建。
-
-受管前先保存 finalizer。删除期间查询 Database 引用（包括 Released/删除中）及未绑定
-Tenant；存在引用或查询失败都等待，无引用才解除。不得级联删除数据库或凭据。
-finalizer 不阻止并发申请 CR 创建；新请求见 Instance 删除中/不存在时不得供应。
-不引入跨对象锁，不声称列表与删除之间存在原子事务。
-
-## 验收与实现差距
-
-领域单测覆盖缺项、旧配置、错误目标、扩展空集合与未观察、重验与删除禁用。
-真实 API server 验证 Secret、resourceVersion、watch、finalizer；真实 PostgreSQL 验证
-权限、TLS、凭据更新和查询失败，不以领域布尔值或 server_version 查询代替管理权限验收。
-
-Instance 领域代码、adapter 与测试的 registry 依赖已撤除。AssessManagement 根据完整观察
-直接完成验证；AssessReadiness 失败进入 Validating，依赖恢复后重新验证。领域测试覆盖各检查项
-在这两个入口的失败与恢复，但完整权限探测、Instance controller 和三资源生命周期尚未完成。

-# Database 领域模型
-
-状态：资源模型已确认，字段与绑定协议待细化。日期：2026-09-25。
-行为以 [系统规格](specification.md) 为准；决策依据见
-[ADR-0009](../decisions/0009-database-resource-and-claim.md)。
-
-## 统一语言与关系
-
-| 术语 | 含义 |
-| --- | --- |
-| Instance | 平台登记的 PostgreSQL 资源来源与管理入口 |
-| Database | 独立存在的数据库资源，保存目标、管理范围、绑定与回收策略 |
-| Tenant | 用户对数据库的申请与使用合同 |
-| Binding | Database 与 Tenant 的排他关联，不是独立 Claim 或 registry |
-| LoginRole | 当前单数据库场景中兼任 owner 的登录角色 |
-| CredentialLocation | 与资源生命周期一致的凭据定位，不是密码 |
-| CredentialProjection | 面向当前使用者的凭据投射要求与观察 |
-
-Instance 一对多 Database；每个 Database 同时零或一个 Tenant，Tenant 最多一个 Database。
-Instance 不持有全部资源的内存集合。三者以引用关联，操作一个资源无需加载整个实例集合。
-
-Instance 与 Database 是集群级资源，Tenant 位于 namespace。Tenant 按名称引用 Database，
-Database 记录所绑定 Tenant 的 namespace/name/UID。Database 不属于应用 namespace；
-平台管理员管理资源及回收策略，普通申请者不能自行将 Released 资源重新开放。
-
-Database 的 instanceRef 表达资源归属，手工登记时也必须提供，不从 Tenant 反推。
-Tenant 动态申请才选择 Instance；引用已有 Database 时使用资源声明的 Instance。
-释放使用绑定不改变 Database 的实例归属，修改引用不能实现外部数据库迁移。
-
-Database 不再是 Tenant 内的无独立生命周期描述。原 OwnershipClaim 不再作为独立领域能力：
-排他绑定是资源自身的不变量，Kubernetes 保存记录，不另建 PostgreSQL 所有权存储。
-
-## 职责
-
-Instance 只接收观察并判断当前连接、metadata、管理权限和扩展支持，不访问 IO、不初始化
-registry。管理凭据来源和连接刷新由应用层协调，连接池由 pgxpool 实现。见
-[Instance 规格](domain-instance.md)。
-
-Database 保护目标和管理范围、排他绑定、导入验证与 Retain/Delete 规则。资源首次外部操作前
-必须已有持久记录；完成记录与外部存在性分别检查。数据库名称不是归属证明。
-
-Tenant 表达申请与交付要求；可显式申请未绑定且可用的资源，不增加反向授权名单。
-绑定后检查数据库满足要求、
-应用凭据可登录且 ESO 投射完成，才可 Ready。Tenant 删除意味着释放使用关系。
-
-第一版 Database 的生命周期边界包含一个 database、一个兼任 owner 的 LoginRole 及其
-应用凭据。LoginRole 与 CredentialLocation 随 Database 保留，不能因为 Tenant 消失就
-失去定位或未经授权被删除；导入时的管理授权与具体字段仍需评审。不新增 Role、Credential
-或 Claim CRD，也不预留多账号集合；若出现一库多账号的实际需求，再通过后续 API 版本演进。
-
-## 生命周期与恢复
-
-- 动态创建与显式导入最终形成同一种 Database 资源，但导入本身不允许改密、改 owner 或删除。
-- Retain 后 Database 保持 Released 与旧绑定身份，人工确认数据、权限和凭据后才可重新绑定。
-- 回收策略属于资源侧；Tenant 与 Database 不是可随申请级联 GC 的父子关系。
-- 回收策略默认 Retain，进入删除流程前可由资源管理者修改，进入后固定；Delete 无额外审批。
-- 动态凭据位置按 Database UID 确定，导入显式关联已有凭据；Released 不自动改密。
-- 绑定 UID 防止同名新申请继承权限。双向记录的单边写入不代表绑定完成。
-- 动态 Database 名称由 Tenant UID 确定；先持久化资源侧 Tenant 引用，再更新 Tenant status
-  的 Database 引用。后一写入失败由 reconcile 核对身份后补齐，不回滚资源侧记录；
-  其他 Tenant 已占用则报冲突。双向一致后才供应或交付，绑定不等于 Ready。
-- 普通失败按 reconcile 重试；可靠确认的步骤幂等继续；不确定创建/未知同名对象报告 Conflict。
-- Kubernetes status 是持久进度和观察，不是外部事实，也不是 controller 内存。
-  不引入“status 任意丢失后自动恢复所有权”的附加要求。
-
-## 分层
-
-| 层 | 责任 |
-| --- | --- |
-| 领域 | 值、身份、允许动作、不变量、完成与冲突判定；不做 IO |
-| 应用 | 装载记录与事实、协调 API 更新和 adapter、回读、交回领域判定 |
-| controller | watch/调度、调用用例、请求资源呈现与安排重试；不判断绑定资格 |
-| adapter | Kubernetes 资源映射与呈现（含 conditions/status/finalizer）、后端访问与安全错误分类 |
-| 装配 | 客户端与成熟连接池的生命周期，不是领域状态 |
-
-不引入通用 Repository CRUD、跨系统 Unit of Work、事务队列或第二套 phase 存储。
-resourceVersion 解决 API 对象并发更新，不宣称 PostgreSQL 与 Kubernetes 原子提交。
-
-绑定实现中，`domain/binding` 承载请求默认值、资源身份匹配、实例就绪与排他绑定规则；
-`application/BindingService` 协调固定申请、资源侧写入和回读确认，返回待呈现结果。
-两层均不依赖 Kubernetes API 类型。`adapter/kubernetes/BindingResources` 将 CR 转换为事实
-快照，并负责保留其他字段、检查快照版本、写入 finalizer 和呈现 Conditions/status。
-controller 仅连接事件、service 与呈现层，不把资源写入细节和领域判断塞进 Reconcile。
-这里的接口只列出绑定用例所需操作，不扩展成通用 CRUD、Repository 或事务框架。
-
-## API 切片前需明确
-
-- 引用与绑定字段的最终格式及校验、管理员与 controller 的权限落实。
-- 资源侧回收策略与 Tenant/Database finalizer 配合。
-- 导入时角色/凭据的管理范围及关联字段、旧使用者撤权及投射清理。
-- 绑定/导入同一实际目标的重复声明如何拒绝，且不引入 registry。
-- 管理员确认冲突、解除旧绑定的具体可审计操作入口。

-# 现有数据库导入与迁移 Runbook
-
-| 项目 | 内容 |
-| --- | --- |
-| 状态 | Review；尚未在临时 PostgreSQL 演练 |
-| 适用范围 | 管理员显式导入，或通过 dump/restore 迁移到新资源 |
-| 最后更新 | 2026-09-24 |
-
-当前设计支持管理员显式登记已有 Database；未知同名资源仍不得自动认领。
-导入不要求移动数据，不隐含改密码、owner、授权或删除权限。API schema 与绑定协调已实现，
-但导入观察和凭据交付尚未实现，以下导入步骤
-是验收要求而非可直接执行的命令。
-
-## 显式导入与保留资源复用
-
-1. 核对 Instance、数据库、owner、角色权限、扩展、使用者与备份，确定允许管理的范围。
-2. 由管理员声明 Database，指定已有目标，回收策略默认 Retain；导入验证初始只读。
-3. 安全关联现有应用凭据；具体 API 待定，不把密码写入 CR，不因验证失败重置密码。
-4. Tenant 显式引用未绑定且可用的 Database；controller 验证要求并建立排他绑定，无额外名单审批。
-5. 验证实际登录与 ESO 交付；不满足时停止，不以修改原数据库作为默认修复。
-
-Released 资源复用前另需核实旧使用者的访问权限、数据交接与投射处置。保留旧绑定身份直到
-人工处理完成，不仅靠清空 claimRef 或修改 UID 授予新使用权。
-
-导入失败时原数据库应保持不变；撤回登记不得触发 Delete。绑定后的回退按 Retain 释放，
-检查新投射与访问授权的影响，不能承诺撤回 CR 自动恢复此前所有外部访问状态。
-
-## 可选的 dump/restore 路径
-
-不适合直接导入、需要改变 owner/权限模型或移动数据时，可使用下述逻辑迁移流程。
-它不是纳管现有数据库的唯一路径；保留旧资源作为限时回滚点。
-
-以下命令是顺序模板，不可原样复制到真实环境。先把尖括号变量解析成明确值，确认当前
-连接目标，再逐条执行。dump 可能包含敏感业务数据，必须放在加密临时存储且不得提交 Git。
-
-## 前置条件
-
-- 已验证 PostgreSQL/OpenBao 备份和恢复；记录恢复点。
-- Instance 已 Ready，目标 namespace 存在，ESO ClusterSecretStore Ready。
-- 最终 database/login role 当前由旧应用占用，但改名后的保留名称、新推导的 Bao path
-  均不存在。
-- 已记录旧 database owner、grants、extensions、locale/encoding、连接配置和验证清单。
-- 已确认应用可停止写入，并确定回滚窗口和负责人。
-- 已确认旧 login role 不被其他 database/应用共享，且角色改名不会破坏未纳入本次维护
-  的依赖。
-
-## 迁移顺序
-
-### 1. 盘点与预演
-
-```sh
-pg_dump --schema-only --no-owner --no-privileges \
-  --dbname='<old-admin-connection>' > schema-preview.sql
-```
-
-检查不受 v1alpha1 管理的对象：额外 roles、跨库依赖、FDW、large objects、订阅、显式
-tablespace、owner/grant 和目标实例不支持的 extension。无法映射为单 database + 单 login
-owner 的环境必须先人工简化，不能让 controller 猜测。
-
-### 2. 创建一致性 dump
-
-停止应用写入并确认活跃写事务结束，然后创建最终 custom-format dump：
-
-```sh
-pg_dump --format=custom --no-owner --no-privileges \
-  --file='<secure-temp>/tenant.dump' \
-  --dbname='<old-admin-connection>'
-pg_restore --list '<secure-temp>/tenant.dump'
-```
-
-不要删除旧 database/role。记录停写时间、dump checksum 和 PostgreSQL 版本。
-
-### 3. 释放最终名称
-
-保持应用停写，终止旧 database 的应用连接。连接其他管理 database，以管理员身份把旧
-database 和旧 login role 改为明确的保留名称：
-
-```sql
-ALTER DATABASE <old_database> RENAME TO <old_database>_retained_<timestamp>;
-ALTER ROLE <old_login_role> RENAME TO <old_login_role>_retained_<timestamp>;
-```
-
-identifier 必须由管理员工具安全引用，不能把未经校验的值直接拼入 SQL。PostgreSQL 在
-角色改名时会清除以旧角色名加盐的 MD5 密码；使用 MD5 的旧环境必须在维护前准备安全的
-密码重设/回滚方法。SCRAM verifier 不受角色名改动影响，但仍须实际验证回滚登录。
-
-### 4. 创建受管空目标
-
-应用 `PostgreSQLTenant`，使用未被占用的 database/loginRole，等待 Ready。确认：
-
-- Database/Instance 身份及 Tenant 排他绑定正确；
-- OpenBao 凭据位置与 Database 管理范围及当前交付授权一致；
-- ExternalSecret Ready 且目标 Secret 已投射；
-- 新凭据可以通过 DNS host 和 IP hostaddr 分别登录空 database。
-
-### 5. Restore
-
-从 OpenBao 或目标 Secret 安全取得新应用凭据，不要把密码放进 shell history。以新 login
-owner 连接目标 database：
-
-```sh
-pg_restore --exit-on-error --no-owner --no-privileges \
-  --dbname='<new-application-connection>' \
-  '<secure-temp>/tenant.dump'
-```
-
-extension 应由 Tenant spec 创建。若 dump 仍包含 extension 定义，预演必须确认 restore
-行为幂等；目标实例不支持的 extension 必须在迁移前解决。
-
-### 6. 验证并切换
-
-- 对比关键 schema、表数、行数/校验和、sequence、function 和 migration version。
-- 用新 login 验证读写、migration 和应用健康检查。
-- 将应用配置切换到新 Secret 或 OpenBao URL，保持旧数据库只读/停写。
-- 观察一个约定窗口，确认错误率、连接数和关键业务功能。
-
-### 7. 收尾
-
-回滚窗口结束后，按独立变更删除旧 database/role/旧凭据；它们不属于 controller，禁止
-通过新 Database 的 `Delete` 清理。安全删除 dump 和临时凭据材料，并记录验证结果。
-
-## 回滚
-
-在新目标出现问题且旧资源仍保留时：
-
-1. 立即停止新目标写入。
-2. 评估切换后是否产生新数据；若有，先决定反向迁移或接受丢弃，不能盲目切回。
-3. 将应用连接切回 retained database/role；若必须恢复原名称，先确保新受管目标已用
-   资源侧 `Delete` 完整清理或改用不同名称，再安全地反向执行 rename。
-4. 恢复旧凭据（MD5 环境可能需要重设），验证旧服务。
-5. 保留失败 Tenant 供排障；修改 Database 的 Retain/Delete 策略前明确其外部资源后果。
-
-若已经删除旧资源，则只能使用已验证备份恢复，不再属于本 runbook 的快速回滚。
-
-## 演练验收
-
-发布首个可用版本前，必须在临时 PostgreSQL/OpenBao/Kind 环境执行本文并记录：
-
-- 显式导入的管理权限、Released 重新开放前的旧访问处置和失败不修改原资源；
-- 使用的 PostgreSQL major version 和命令版本；
-- dump/restore 返回码和对象差异；
-- DNS/IP TLS 登录结果；
-- ESO 投射与应用启动结果；
-- 回滚演练结果；
-- 哪些命令或前置检查需要修订。
-
-完成演练前，本文不得标记为 `Verified`。

-# 运维与故障处理
-
-状态：设计合同，操作入口待 API 实现与隔离环境演练。日期：2026-09-24。
-依据 [系统规格](specification.md)，不再查询或维护 PostgreSQL registry。
-
-## 当前绑定切片的限制
-
-源码已接入绑定 controller，未接入 PostgreSQL 供应、OpenBao/ESO 交付或删除清理。
-Bound/BindingComplete 只表示 Kubernetes 双向记录一致，Ready 仍为 False。
-Tenant 删除会保留 `database.ayatori.ddupan.top/tenant-protection` 并报告 DeletionPending；
-Database 的 `database.ayatori.ddupan.top/database-protection` 也尚无清理后移除路径。
-这是未完成能力的明确边界，不是已经实现的 Retain/Delete 恢复逻辑。不要将此切片部署为
-业务 DBaaS，也不要为了消除等待状态直接移除 finalizer；后续必须补齐清理与验收。
-
-## 日常检查
-
-先看 Instance、Database、Tenant 的 Ready Condition、绑定 UID、阶段与 observedGeneration，
-再核对 PostgreSQL catalog、OpenBao metadata、ExternalSecret 与 Secret 投射状态。
-具体 kubectl 资源名、finalizer 名称与人工确认字段在 API 实现后补齐，不提供猜测的 patch 命令。
-不得把 Secret data、密码或带 Token 的请求粘贴到 issue/日志。
-
-## 故障分类
-
-| Reason/状态 | 首要检查 |
-| --- | --- |
-| InvalidSpec / ImmutableField | 请求、名称、不可变目标与只追加扩展约束 |
-| DependencyUnavailable | 网络、DNS、服务状态和超时；恢复后退避重试 |
-| AuthenticationFailed | 管理 Secret、TLS、OpenBao auth |
-| InsufficientPrivileges | PostgreSQL/OpenBao 权限与 Kubernetes RBAC |
-| InstanceNotReady | 当前目标的管理能力，不检查 registry |
-| Conflict | 绑定 UID、未知同名资源、失败步骤与外部结果确定性 |
-| CredentialProjectionFailed | 授权的凭据位置、Store、ESO 与目标 Secret |
-| Released | 资源已保留，不代表可直接交给另一个 Tenant |
-
-## 创建不确定或同名冲突
-
-1. 保留 CR、绑定与安全诊断，不清空 status、不反复删除重建申请。
-2. 核对确切 Instance/database/role 和凭据位置；区分已确认完成与结果不确定的操作。
-3. 使用只读检查确认资源内容、使用者和权限，不通过重设密码来“验证归属”。
-4. 管理员决定清理确定的残留后重试，或显式导入保留资源；涉及删除需另有明确授权。
-5. 记录处理依据，再按 API 的受控入口恢复协调。
-
-普通依赖故障可以自动继续，未知归属不得因后端恢复就自动认领。
-controller 重启保留 Kubernetes 中的记录，不需要恢复第二套 registry。
-
-## Retain 与重新绑定
-
-Tenant 删除后 Database 及实际资源保留，进入 Released，保存旧绑定身份。
-不要删除 Database 对象来“释放名称”，也不要只修改 UID 或 Ready 强行交付。
-
-管理员先确认数据是否允许交给新使用者、旧角色是否共享、旧账号访问如何撤销或保留、
-新使用者如何获得凭据，以及原 ExternalSecret/Secret 的处置。删除 Secret 不会撤销已持有密码
-的 PostgreSQL 访问。完成这些处置后，才通过显式授权重新绑定；不自动回到可分配状态。
-具体凭据关联与解除绑定字段尚待 API 评审，当前不能宣称已有可执行恢复命令。
-
-## Delete 卡住
-
-核对 Database/Instance/绑定身份、资源侧 Delete 授权及实际管理范围，修复相关依赖，
-让 controller 从已确认的步骤继续。不要删除共享角色或未纳管凭据，不使用扩大范围的 CASCADE。
-
-依赖永久丢失时列出每个可能残留的数据库、角色、凭据与投射。只有管理员接受残留与后续处置
-责任后才人工移除确切对象的 finalizer。该操作不会完成清理，也不会授权新申请使用残留资源。
-
-## 备份与恢复
-
-分别备份 PostgreSQL 数据、Kubernetes 资源与绑定记录、OpenBao 数据及必要配置。
-不再要求备份专用 registry。只复制在线磁盘不等于有效数据库备份；秘密备份必须加密并限制访问。
-
-灾难恢复先暂停 controller，核对三者恢复点、UID、外部目标与凭据的一致性，再恢复协调。
-不一致时按 Conflict 人工处理，不承诺仅凭外部同名数据库重建丢失绑定。
-在隔离环境演练登录、导入、Retain、重新绑定与 Delete 后才能标记验证通过。
-
-## 紧急停止
-
-疑似越权删除或秘密泄漏时暂停 controller，保留 CR 与脱敏证据，限制相关管理身份权限，
-在隔离环境复现并确认修复后恢复。一般依赖失败不需要停机。

-# 安全模型
-
-| 项目 | 内容 |
-| --- | --- |
-| 状态 | Review |
-| 最后更新 | 2026-09-24 |
-
-## 保护目标
-
-- 应用密码只存在于 OpenBao、ESO 投射的目标 Secret 和需要使用它的进程内存中。
-- controller 只能在 Database 已确认的管理范围和当前绑定/操作授权内修改资源；未知同名对象报冲突。
-- namespace 租户不能越权管理 Instance、Database 导入/回收、其他 namespace 或 controller 配置。
-- PostgreSQL 和 OpenBao 的网络身份使用受信 CA 验证，不因 DNS 不可用而降级 TLS。
-
-## 信任边界
-
-Kubernetes 管理员、OpenBao 管理员和 PostgreSQL 管理员是平台信任主体。能读取 Tenant
-目标 Secret 或对应 OpenBao path 的主体等同于持有数据库账号。database owner 可以
-改变自己 database 内的对象，因此 COMMENT 不能作为 controller 所有权依据。
-
-数据库备份包含业务数据；Kubernetes 保存资源与绑定记录；OpenBao 保存应用凭据。
-完整灾难恢复必须分别保护三者并核对恢复点，不依靠数据库内 registry 重建绑定。
-
-## 凭据处理
-
-- controller 使用 Kubernetes auth 获取短期 OpenBao token，不配置长期静态 token。
-- 管理凭据只从 Instance 引用的 controller namespace Secret 读取，不复制到
-  CR/status/Event/metric/trace；管理员维护 ExternalSecret，由 ESO 同步该 Secret。
-- 动态供应密码使用密码学安全随机源；已有可靠关联时复用 OpenBao 现值，结果不确定时停止并报冲突。
-- controller 创建 ExternalSecret，不直接创建含 data/stringData 的 Secret。
-- 日志字段允许 namespace/name、UID、generation、阶段和错误类别；禁止记录请求/响应体、
-  DSN、Authorization header、密码或完整 OpenBao URL path 作为 metric label。
-- panic、错误包装和测试失败输出必须经过凭据泄漏测试。
-
-## TLS
-
-- homelab 默认 `verify-full`，`disable` 只允许显式开发配置。
-- server 证书同时覆盖 DNS `host` 和 IP `hostaddr`；消费者自行选择连接目标。
-- OpenBao PKI 保管 CA 私钥并负责签发/续期。controller Deployment 只挂载公开 CA
-  bundle，挂载只读且使用最小文件权限。
-- 证书轮换必须先发布同时信任新旧 CA 的 bundle，再轮换服务端证书，最后移除旧 CA。
-
-## 最小权限
-
-OpenBao controller identity 只管理固定 tenant base path，不读取管理凭据。管理凭据
-ESO 身份只读管理路径，租户 ESO 身份只读 tenant base path，二者隔离，Tenant 不得
-使用管理凭据 Store。controller 对管理 Secret 的读取限于自身 namespace，Instance
-不能指定其他 namespace；controller 不创建或修改管理 Secret／ExternalSecret。
-
-PostgreSQL 管理 role 不应是 superuser。若平台选择 SECURITY DEFINER 函数承载创建或
-删除操作，函数必须固定 `search_path`、严格校验 identifier、拒绝任意 SQL，并仅向
-controller role 授予 EXECUTE。controller 不调用 shell 或 `psql` 拼接用户输入。
-
-Kubernetes RBAC 应把 Instance 管理、Database 导入、Released 重新开放和回收限制给平台管理员。
-有权创建 Tenant 的申请者可显式申请未绑定且可用的 Database，不增加资源侧允许绑定名单
-或逐 Tenant 审批。Released 必须先由管理员处理旧访问并重新开放。Tenant editor
-不自动获得 Secret read；是否读取目标 Secret 由 namespace 内独立 RBAC 决定。
-
-## 删除保护
-
-资源侧 Delete 是明确的数据销毁授权，但仍必须在每一步校验 Instance/Database UID、
-绑定、实际目标及角色/凭据管理范围；CR 中记录了意图不等于外部对象由本系统创建。
-禁止对未知对象使用 `CASCADE`。删除 finalizer 卡住时只能按
-[`operations.md`](operations.md) 核实外部状态后人工移除；该操作可能遗留资源。
-
-## 发布前安全验收
-
-- 使用错误 CA、错误 DNS 名和错误 IP 时连接失败；正确 DNS/IP SAN 均成功。
-- namespace 用户不能修改 Instance 或跨 namespace Tenant/ExternalSecret。
-- controller/ESO 的 OpenBao policy 互相隔离，越权请求被拒绝。
-- 应用 login 不能创建 role/database，也不能连接其他租户 database。
-- 日志、Event、Condition、metrics、CR 导出和测试 artifact 不含 canary password/token。
-- 伪造 COMMENT、同名 database/role 或错误 UID metadata 均不能绕过 Conflict。
-- Delete 只销毁 Database 已确认管理范围内且获得删除授权的资源。
-- 导入检查不改密码/owner，Released 不自动授权新使用者；旧访问处理后才能重新交付。
-- 导入默认 Retain；角色/凭据的管理与删除范围未明确时不得扩大操作范围。

-Database 自身必须声明 `instanceRef`，手工登记时同时指定实际数据库名；无需先存在 Tenant，
-即可通过 Instance 验证目标。动态申请由 Tenant 选择 Instance，供应时把该引用写入 Database；
-选择已有 Database 的 Tenant 从资源获取 Instance，不重复指定另一份来源。资源与实例的归属
-独立于使用绑定，Tenant 删除后仍保留；修改引用不是数据库迁移。
-
-参考 [Kubernetes PV/PVC](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) 的
-资源/申请分离与绑定生命周期，不复制存储调度和 CSI 协议。资源与申请的关系不是 GC 所有关系。
-
-## 3. 身份与事实来源
-
-- Kubernetes spec 保存声明；受保护的资源绑定记录与 status 保存身份关联、操作进度和观察。
-  它们通过 API 持久化，不因 controller 重启而消失。
-- PostgreSQL catalog 是 database、role、grant、extension 实际状态的来源。
-- OpenBao 是应用凭据的事实来源；ESO 状态和目标 Secret 存在性说明投射结果。
-- Instance、Database、Tenant 以 UID 区分对象身份；namespace/name 用于定位，
-  同名新 UID 不继承旧绑定。数据库 OID 仅供诊断，不是永久身份或删除授权。
-- 不新增 PostgreSQL 所有权表、安装身份表或 Retain 墓碑；COMMENT 也不能授权认领。
-- 记录操作意图不等于外部操作成功，phase 不等于外部所有权；执行前后仍须观察实际状态。
-
-## 4. Instance 合同
-
-Instance 声明 host、hostaddr、port（默认 5432）、管理 database（默认 postgres）、
-TLS mode（默认 verify-full）及 controller namespace 的管理 Secret 名称和字段映射。
-禁止隐式 TLS 降级。凭据引用不接受自选 namespace 或 OpenBao path。
-
-管理员维护 ExternalSecret，由 ESO 同步管理 Secret；controller 只读，不修改管理密码，
-不直接从 Bao 取管理凭据。有效用户名或密码变化时释放旧连接并重验；仅 metadata 或无关
-字段变化不重建。中途凭据变化必须丢弃旧观察。已有有效管理凭据时，Bao/ESO 故障本身
-不撤销 Instance Ready；首次缺少有效 Secret 时不能 Ready。
-
-Ready 要求当前目标的连接、服务器 metadata 和所需管理能力检查通过，不要求创建、
-迁移或读取 registry，也不证明备份或高可用。阶段简化为 Pending → Validating → Ready，
-删除进入 Deleting。实际扩展可用列表不等于安装权限；查询失败不等于不支持。
-
-endpoint 变更由管理员负责评估，不验证物理服务器连续性，不迁移或清理旧目标；
-旧观察失效。新 UID 不接管旧资源。Instance 开始受管前保存 finalizer；删除时停止新供应，
-只要有引用它的 Database（包括 Released/删除中）或尚未绑定的 Tenant 就等待。
-查询失败不视为无引用；无引用才解除 finalizer，不级联删除任何业务资源。
-引用检查不是跨对象事务，正在删除或不存在的 Instance 不允许开始新的供应/绑定。
-
-## 5. 动态供应与排他绑定
-
-1. 校验 Tenant 请求、Instance 能力、名称和扩展要求。
-   绑定 controller 在触及资源侧绑定前将 Tenant 进度记为 Binding，固定申请目标，
-   避免两次绑定写入之间修改引用占用第二个资源；该进度不是已绑定的声明。
-2. 在首次外部写入前持久化独立 Database 记录、确定目标与管理范围。
-   动态创建的 Database 名称由 Tenant UID 确定；重试复用同一记录，不重复创建。
-3. 先在 Database 写入 Tenant namespace/name/UID，再在 Tenant status 写入 Database
-   name/UID；双向记录一致后才允许供应或交付。
-4. 按已确认步骤建立凭据、role、database、授权和扩展，逐步回读。
-5. 验证应用登录与 ESO 投射后，Tenant 才可 Ready。
-
-绑定前固定有效目标；绑定或开始外部供应后不得通过修改名称或引用实施隐式迁移。
-每个 Database 最多一个使用者，每个 Tenant 最多一个 Database。
-绑定 API 写入采用 resourceVersion 并发控制；双向记录不原子，单边完成不得授予使用权限。
-采用 Kubernetes PV/PVC 的资源侧先写模式，参考
-[官方 bind 实现](https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/volume/persistentvolume/pv_controller.go)。
-Database 已绑定其他 Tenant 时报告 Conflict，不抢占；API 更新版本冲突时重新读取并判断，
-不能盲目覆盖。资源侧成功而 Tenant status 写入失败时，下一次 reconcile 核对双方身份后
-补写，不因单次失败撤销资源侧绑定。普通 controller 重启沿用这些持久记录继续协调。
-这只处理 Kubernetes 绑定记录的部分完成，不提供外部数据库不确定创建结果的自动认领。
-绑定成功不代表 Ready，具体字段及并发、重启、单边写入恢复必须由真实 API server 测试验证。
-
-不同 Database 记录请求同一外部名称仍可能竞争，不能仅靠 Kubernetes 中的列表检查保证
-PostgreSQL 名称唯一。后端创建时的重名失败报告 Conflict，失败方不得接管胜方资源。
-不为此新增跨系统锁或 registry。管理员也不得把同一物理数据库登记成多个可绑定资源。
-
-## 6. 显式导入
-
-管理员创建资源声明，明确 Instance、已有数据库和允许管理的范围，构成导入授权。
-初始检查只读验证存在性、owner、角色权限和扩展等是否匹配；不匹配报告清楚的差异，
-不得通过重置密码、改变 owner 或撤销现有访问来“完成导入”。
-
-未显式导入的同名数据库一律 Conflict。导入资源默认 Retain，不隐含 Delete 授权。
-有权创建 Tenant 的申请者可以显式引用已登记、未绑定且可用的 Database；不增加资源侧
-允许绑定名单或逐 Tenant 的管理员审批。绑定仍检查目标、可用状态与排他关系。
-Released 不在可申请范围，必须由管理员处理旧访问并重新开放。导入时显式关联已有凭据，
-不通过隐式改密生成替代凭据；具体关联字段在 API 中定义。
-
-## 7. Retain、重新绑定与 Delete
-
-回收策略属于 Database，默认 Retain；Tenant 删除是释放申请，不是独立资源的 GC 授权。
-有资源管理权限的主体可在进入删除流程前修改 Retain/Delete；进入删除流程后策略固定。
-显式设置 Delete 就是删除授权，不增加第二次审批或确认字段。
-Database 不得设置会让它随 Tenant 消失的 ownerReference。
-
-### Retain
-
-- 保留 Database 对象、外部数据以及与资源关联的角色和凭据，不自动删除或重置。
-- Tenant 释放后 Database 进入 Released，保留旧绑定身份用于诊断和防止自动复用。
-  Released 不是 Available，不再向原申请交付新状态，也不自动分配给同名新 Tenant。
-- 保留策略不要求 PostgreSQL/Bao 在线才能完成申请释放，但必须先将释放关系安全记录到
-  Kubernetes；API 写入失败时不能宣称释放完成。仍有在途操作时不得跳过必要协调。
-- 管理员检查数据、旧账号访问与凭据后，显式授权重新绑定。保留数据的复用可以不清空数据，
-  但必须由管理员确认新使用者应获得这些数据及旧使用者的权限处置。
-- 删除旧投射 Secret 或解除绑定不等于撤销 PostgreSQL 访问；Retain 不承诺自动撤权。
-  ExternalSecret/Secret 的保留与清理细节需随凭据交付协议明确。
-
-### Delete
-
-必须由有权限的主体在资源侧明确授权，并核对 Database 身份、绑定、实际对象和管理范围。
-在相关 finalizer 保护下清理投射、阻止新登录、处理已有连接、删除 database，再按已确认的
-独占管理范围清理 role 与凭据；共享或未纳管的对象不得删除，禁止扩大 CASCADE 范围。
-
-每步回读，失败保持进度与 finalizer；确认已删除的对象可幂等跳过，未知同名对象不能继续删除。
-数据库被使用时，直接删除 Database 不得绕过绑定保护。资源已释放后才按策略处理。
-具体 Tenant/Database finalizer 配合与投射清理顺序须经 API 设计及故障注入验收。
-
-## 8. 幂等、失败与人工处理
-
-普通依赖故障退避重试。已持久确认且仍与观察一致的步骤可以幂等继续；controller 重启
-不重新生成密码，不重复创建已确认资源。
-
-外部创建成功但记录尚未保存，或超时导致结果不确定时，若不能可靠确认归属，报告
-Conflict 并停止相关写入；不得仅凭名称相同、曾记录意图或字段相似自动认领。
-失败恢复不承诺全部自动完成，也不实现队列模拟事务。
-
-status 缺失不假定发生于正常重启。Instance 可重新探测能力；Database/Tenant 缺少绑定或
-操作确认时不能从外部同名对象推导所有权。按冲突/灾难恢复处理，不自动重建所有权表。
-
-人工处理必须能看到：请求与资源身份、目标 Instance/database/role、失败步骤、已确认完成
-与结果不确定的操作、冲突原因、下一步核实建议。保留现场，不自动删除疑似残留或改密。
-管理员核实后可清理确定的残留再重试，或走显式导入；不能通过伪造 Ready/清空 status 强行继续。
-
-## 9. 权限、凭据与扩展
-
-动态供应继续使用一个兼任 database owner 的 LOGIN role；应用角色不得具备 superuser、
-CREATEDB、CREATEROLE 或 replication 权限。撤销 PUBLIC CONNECT，再授予目标角色；
-不修改无关数据库和角色。identifier 匹配 `^[a-z][a-z0-9_]{0,62}$`，SQL 安全引用。
-
-请求扩展按实例实际可用集合判断，成功后只追加，不自动 DROP EXTENSION。
-可用列表查询失败按依赖错误处理；实际安装仍检查权限与结果。
-
-应用密码使用安全随机源，只写 OpenBao；已有可信凭据可复用，不因失败生成第二份密码。
-新建时先安全保存并回读凭据，再创建角色；凭据写入本身结果不确定也适用人工冲突规则。
-Kubernetes 应用由 ESO 投射同 namespace Secret，controller 不直接写明文 Secret。
-
-凭据仍输出 username/password/database/host/hostaddr/port/sslmode 七键，不生成带密码 URI。
-Tenant status 提供 Secret 引用与无认证信息的 OpenBao API URL。
-mount/base path 属部署配置，Tenant 不得自选任意路径；原按 Tenant namespace/name 固定
-推导路径的规则撤除。动态供应的凭据路径按 Database UID 确定；导入时显式关联已有凭据
-位置，不要求搬迁已有凭据。Released 不自动改密，管理员处理旧访问后才重新开放资源。
-不得因换 Tenant、改部署参数或重新绑定就隐式搬迁凭据或改密。
-
-TLS、OpenBao Kubernetes auth、controller/ESO 身份隔离、Secret 读取范围和防泄漏要求
-见 [安全模型](security.md)。这些安全约束继续适用。
-
-## 10. Conditions 与可观测性
-
-三类资源均提供唯一的 Ready Condition 及 observedGeneration，phase 只辅助表示阶段。
-Ready=True 必须有当前目标的实际验证；Database 已绑定不等于 Tenant 凭据交付已经完成。
-
-至少区分 Reconciling、InvalidSpec、ImmutableField、DependencyUnavailable、
-AuthenticationFailed、InsufficientPrivileges、InstanceNotReady、Conflict、
-ProvisioningFailed、CredentialProjectionFailed。Released 应明确显示未可供重新绑定，
-具体 Condition Reason 由 API 细化，不假定仅靠 phase 判断授权。
-
-使用结构化日志、Events 和低基数失败分类 metrics；Condition 是面向使用者的主要诊断入口。
-禁止在任何 CR、Event、日志、metric、trace 或测试输出中出现密码、Token、完整秘密响应。
-
-## 11. 验收
-
-| 场景 | 必须验证的结果 |
-| --- | --- |
-| Instance 登记与重验 | 无 registry 依赖；真实凭据/TLS/管理权限检查 |
-| 动态供应与重复 reconcile | 独立资源记录、排他绑定、密码不变、实际登录与投射成功 |
-| 显式导入 | 无数据/密码/owner 隐式修改；错误目标、已占用或 Released 资源的申请被拒绝 |
-| 同名未知资源 | Conflict，原数据库/角色/凭据不变 |
-| 并发申请与单边绑定 | 最多一个使用者；失败方不能开始危险外部操作 |
-| controller 重启 | 已确认步骤正常继续；不确定创建报告人工可诊断冲突 |
-| Retain 与 namespace/Tenant 删除 | Database 不被 GC，外部数据保留，Released 不自动复用 |
-| 人工重新绑定 | 旧 UID 不继承使用权；确认数据及凭据/旧访问处置后才能交付 |
-| Delete 每步中断 | finalizer 保留，可重试，不误删未知/共享/未纳管对象 |
-| 依赖稍后出现/权限恢复 | 安全重试，过期观察不授权写入 |
-| status/备份恢复不一致 | 不凭同名推导归属，明确人工处理范围 |
-| 泄漏与权限 | canary 不出现在输出；namespace 用户不能导入/回收他人资源 |
-
-纯规则用单元测试；schema/CEL/status/watch/resourceVersion/绑定事件链用 envtest；
-真实 PostgreSQL/OpenBao 验证后端行为；GC、ESO 与完整交付用具备相应控制器的测试集群。
-envtest 不运行 GC/ESO，不能据此宣称这两类验收完成。详细测试与实现差距见
-[开发文档](development.md)。导入不是数据迁移，dump/restore 仍是可选路径，见
-[迁移文档](migration.md)。

-
-- 状态：Accepted（资源模型与生命周期）；API 字段细节待评审
-- 日期：2026-09-24
-- 依据：维护者本轮设计讨论；本决定部分替代 [ADR-0008](0008-merge-postgresql-tenant-operator.md)
-  对 ownership registry、自动恢复与 Retain 的沿用要求，不改变 Database 合并归属。
-
-## 问题
-
-原模型让 Tenant 同时表示用户申请和外部资源生命周期，又用 PostgreSQL registry 在 Tenant
-删除后保留所有权。它把简单的一对多关系扩展成额外持久化协议，并为“外部创建成功但 status
-未写入”承诺自动认领恢复。这里并没有自动恢复所有不确定结果的产品要求；清楚报告冲突、
-保留现场并允许人工处理是可接受的合同。
-
-Kubernetes status 存储在 API/etcd 中，不是 controller 重启即丢失的内存。外部操作与 API
-写入之间确实存在失败窗口，但不因此引入第二套所有权数据库或模拟跨系统事务。
-
-## 参考与取舍
-
-参考 Kubernetes 官方 [Persistent Volumes](https://kubernetes.io/docs/concepts/storage/persistent-volumes/)：
-资源独立于申请存在，绑定排他；Retain 释放后需要人工处理；已有资源可以静态登记。
-同时参考 [owner references](https://kubernetes.io/docs/concepts/overview/working-with-objects/owners-dependents/)
-与 [finalizers](https://kubernetes.io/docs/concepts/overview/working-with-objects/finalizers/) 的生命周期边界。
-
-采用这些模式，不直接使用 PV/PVC 类型，不实现 CSI 协议，不引入 StorageClass、容量匹配、
-调度器、通用 Claim、事件总线或额外 registry。Instance 是资源来源与管理入口，PostgreSQL
-adapter 承担类似驱动的访问职责；Instance 本身不是 CSI 驱动。
-
-## 决策
-
-- Instance 对应多个独立 Database；每个 Database 同时最多绑定一个 Tenant，Tenant 最多绑定
-  一个 Database。Tenant 是用户申请，不再直接承担持久资源的全部生命周期。
-- Database 是新增 Kubernetes 资源；本文采用 PostgreSQLDatabase 作为工作名称，具体字段、
-  scope 与短名称在 API 评审中确定，不从类比自动推导。
-- 动态供应先建立资源记录；已有数据库只能由管理员显式登记导入。仅发现同名数据库不是授权。
-- Database 自带 instanceRef，手工登记不依赖 Tenant。动态申请由 Tenant 选择 Instance；
-  引用已有 Database 的 Tenant 从资源获取 Instance，不重复声明另一份来源。
-- Retain 默认保留 Database 与外部资源；Tenant 删除后资源进入 Released，保留旧绑定身份，
-  不自动重新分配。管理员处理数据、账号权限与凭据后，才可授权重新绑定。
-- 回收策略在 Database 一侧。Delete 必须具备明确管理范围、删除授权、finalizer 和回读；
-  导入不隐含授权改密码、改 owner、撤权或删除。
-- Kubernetes CR 保存资源身份、绑定与操作进度，PostgreSQL catalog 保存实际数据库状态；
-  不再维护 PostgreSQL ownership registry，不把 registry 初始化或回读作为 Instance Ready 条件。
-- 普通依赖失败继续 reconcile；同名未知资源、创建结果无法确认时报告 Conflict，停止对相关
-  资源的危险操作，提供人工诊断。已有可靠记录支持的幂等步骤可以继续，不将每次重启都变成冲突。
-- status 不承诺在任意删除后自动重建所有权。灾难恢复按备份与人工核实处理。
-- Database 不受 Tenant 的级联 GC 控制；Instance 删除也不能级联删除 Database 或业务数据。
-
-## 保留的合同与未决项
-
-管理 Secret 来源、凭据变化后刷新连接、TLS、实际扩展观察、OpenBao 应用凭据与 ESO 投射、
-最小权限和分层集成验证继续适用。单 database、单 login owner 的首版使用场景不变。
-
-Database 对 role/凭据的具体管理边界、持久凭据定位与重新授权方式、资源 scope、绑定字段、
-预留及并发绑定的 API 更新协议需在 API/实现切片前细化。旧的 Tenant namespace/name 固定
-凭据路径不能未经评估直接用于跨 Tenant 重新绑定；不为填满字段表而默认授权搬迁或改密。
-
-## 实施边界
-
-本次只修订设计。现有 registry adapter、Instance 中的 registry 判定及相关测试是待撤换的旧实现，
-不是新合同的前提；未提交的 registry inspection 不继续接入。后续按新规格撤除这些依赖，
-再实现 Database 资源、绑定、导入与回收的纵向切片，不保留未部署实现的兼容层。
-
-详见 [系统规格](../database/specification.md)、[领域模型](../database/domain-model.md)、
-[API 设计状态](../database/api-reference.md)和[测试合同](../database/development.md)。
