+# IdP 图标上传与清理契约
+
+## 1. Scope / Trigger
+
+- 适用于创建 SAML IdP 前,先把图标上传到 Identity Domains 公共图片存储的流程。
+- 上传先于 IdP 创建,图片在创建成功前是临时远端资源;前端做**尽力清理**,
+  孤儿(自己租户里一张无入口小图)可接受,不为它建所有权状态机。
+
+## 2. Signatures
+
+```text
+POST   /api/v1/oci-configs/{id}/idp-icons?domainId=<optional>
+DELETE /api/v1/oci-configs/{id}/idp-icons?domainId=<optional>&fileName=<required>
+```
+
+```typescript
+uploadIdpIcon(id: number, file: File, domainId?: string): Promise<IdpIconUpload>
+deleteIdpIcon(id: number, fileName: string, domainId?: string): Promise<void>
+
+interface IdpIconUpload {
+  url: string      // 写入 IdP iconUrl 的公网地址
+  fileName: string // 仅用于清理的存储标识
+}
+```
+
+上游 Identity Domains 契约(SDK 未覆盖,走 BaseClient 裸调):
+
+```text
+POST   /storage/v1/Images       multipart: file + fileName
+DELETE /storage/v1/Images       query: fileName
+```
+
+## 3. Contracts
+
+- POST 的 `file` 是唯一文件字段;文件本体最大 `1 MiB`,由 service 精确限制;
+  路由级 body limit 为 multipart 封装开销另留余量,两者不是同一契约。
+- 客户端原始文件名只用于取扩展名。真正上传名由服务端随机生成
+  `idp-icon-<32 lowercase hex><lowercase ext>`:既避免并发/迟到响应下同名互相
+  覆盖,又让存储名成为不可猜测的清理凭据。
+- 内容校验只做**扩展名白名单 + 文件头魔数嗅探**(png/jpg/jpeg/gif/webp/ico/svg),
+  不做深度解码与结构校验:图标由管理员为自己租户上传、由 Oracle 域名托管,
+  传错内容只会让自己登录页图标裂开,深度校验的复杂度与误伤承担不起
+  (2026-07 曾过度实现完整解码套件后精简)。
+- DELETE 只接受单层 `images/idp-icon-<32 lowercase hex>.<allowed ext>`,
+  不得因共享 `images/` 前缀删除其他域资产;上游 404 视为幂等成功,返回 204。
+- 前端上传成功时保存 `{cfgId, domainId, url, fileName}` 原始元组作 pendingIcon,
+  用请求序号丢弃迟到响应;替换、放弃表单或提交未引用它时按元组尽力删除,
+  失败静默。创建请求引用了它且返回 2xx(含 `201 + setupWarning`)即视为已采用。
+- IdP 创建是多步远端事务:创建后 JIT 映射失败先回滚删除刚创建的禁用 IdP;
+  回滚成功按普通失败,回滚失败/无法确认返回 `201` 和
+  `setupWarning{code: JIT_SETUP_INCOMPLETE, resourceCreated, requestId}`;
+  内部原因只按 requestId 写服务端日志,不进响应。
+- 前端在身份设置加载完成前禁用提交;后端创建前再次读取域设置,
+  `primaryEmailRequired=true` 强制 JIT 邮箱映射,查询失败时不创建 IdP。
+
+## 4. Validation & Error Matrix
+
+| 条件 | HTTP |
+| --- | --- |
+| 缺少 multipart `file`、文件为空或文件名非法 | 400 |
+| 文件本体超过 1 MiB | 413 |
+| 扩展名不支持或与文件头魔数不符 | 415 |
+| DELETE 缺少 `fileName` 或不是本服务生成的图标名 | 400 |
+| 上游 DELETE 返回 404 | 204 |
+| IdP 创建后 JIT 失败且回滚无法确认 | 201 + `setupWarning` |
+| 其余上游/内部错误 | 统一错误边界,不泄露上游响应正文 |
+
+## 5. Tests / Verification Required
+
+- 完整路由:恰好 1 MiB → 200、1 MiB+1 → 413、空文件 → 400、伪造扩展名 → 415。
+- 存储名:相同原始名连续上传得到不同随机名;熵源失败不调用上游;
+  DELETE 拒绝非 IdP 前缀、子目录、错误 token 长度/大小写与非允许扩展。
+- 魔数:各允许格式最小样本通过,扩展名与内容不符、未知扩展名被拒。
+- 多步创建:初始创建失败、JIT 失败且回滚成功、回滚失败/ID 缺失三分支;
+  后两者分别锁定普通失败与 `setupWarning` 契约,响应不泄露底层 cause。
+- 域设置:主邮箱必填强制映射、设置查询失败零创建、关闭 JIT 跳过查询。
+
+## 6. Wrong vs Correct
+
+```typescript
+// Wrong:用清理时的 props 删旧图标——弹窗可能已切到别的租户/域。
+onBeforeUnmount(() => deleteIdpIcon(props.cfgId, uploaded.fileName, props.domainId))
+
+// Correct:上传时捕获原始元组,清理只按元组走,失败静默。
+pendingIcon = { ...uploaded, cfgId, domainId }
+void deleteIdpIcon(pendingIcon.cfgId, pendingIcon.fileName, pendingIcon.domainId).catch(() => {})
+```
+
+反例(勿复现):为图标这种低价值临时资源实现「冻结所有权 + 结果未知协议 +
+卸载钩子」的完整状态机,或对上传内容做完整解码/结构/主动内容校验——
+复杂度与威胁模型不匹配,已于 2026-07 精简移除。

+- **测试**:命名派生、legacy 常量值、描述中性性由 `logrelay_names_test.go` table-driven 锁定;若必须调整 legacy 常量,先评估是否会让存量租户找不到既有资源导致重复创建。

-# Code Reuse Thinking Guide
-
-> **Purpose**: Stop and think before creating new code - does it already exist?
-
----
-
-## The Problem
-
-**Duplicated code is the #1 source of inconsistency bugs.**
-
-When you copy-paste or rewrite existing logic:
-- Bug fixes don't propagate
-- Behavior diverges over time
-- Codebase becomes harder to understand
-
----
-
-## Before Writing New Code
-
-### Step 1: Search First
-
-```bash
-# Search for similar function names
-grep -r "functionName" .
-
-# Search for similar logic
-grep -r "keyword" .
-```
-
-### Step 2: Ask These Questions
-
-| Question | If Yes... |
-|----------|-----------|
-| Does a similar function exist? | Use or extend it |
-| Is this pattern used elsewhere? | Follow the existing pattern |
-| Could this be a shared utility? | Create it in the right place |
-| Am I copying code from another file? | **STOP** - extract to shared |
-
----
-
-## Common Duplication Patterns
-
-### Pattern 1: Copy-Paste Functions
-
-**Bad**: Copying a validation function to another file
-
-**Good**: Extract to shared utilities, import where needed
-
-### Pattern 2: Similar Components
-
-**Bad**: Creating a new component that's 80% similar to existing
-
-**Good**: Extend existing component with props/variants
-
-### Pattern 3: Repeated Constants
-
-**Bad**: Defining the same constant in multiple files
-
-**Good**: Single source of truth, import everywhere
-
-### Pattern 4: Repeated Payload Field Extraction
-
-**Bad**: Multiple consumers cast the same JSON/event fields locally:
-
-```typescript
-const description = (ev as { description?: string }).description;
-const context = (ev as { context?: ContextEntry[] }).context;
-```
-
-This is duplicated contract logic even when the code is only two lines. Each
-consumer now has its own definition of what a valid payload means.
-
-**Good**: Put the decoder, type guard, or projection next to the data owner:
-
-```typescript
-if (isThreadEvent(ev)) {
-  renderThreadEvent(ev);
-}
-```
-
-**Rule**: If the same untyped payload field is read in 2+ places, create a
-shared type guard / normalizer / projection before adding a third reader.
-
----
-
-## When to Abstract
-
-**Abstract when**:
-- Same code appears 3+ times
-- Logic is complex enough to have bugs
-- Multiple people might need this
-
-**Don't abstract when**:
-- Only used once
-- Trivial one-liner
-- Abstraction would be more complex than duplication
-
----
-
-## After Batch Modifications
-
-When you've made similar changes to multiple files:
-
-1. **Review**: Did you catch all instances?
-2. **Search**: Run grep to find any missed
-3. **Consider**: Should this be abstracted?
-
-### Reducers Should Use Exhaustive Structure
-
-When state is derived from action-like values (`action`, `kind`, `status`,
-`phase`), prefer a reducer with one `switch` over scattered `if/else` updates.
-
-```typescript
-// BAD - action-specific state transitions are hard to audit
-if (action === "opened") { ... }
-else if (action === "comment") { ... }
-else if (action === "status") { ... }
-
-// GOOD - one reducer owns the transition table
-switch (event.action) {
-  case "opened":
-    ...
-    return;
-  case "comment":
-    ...
-    return;
-}
-```
-
-This matters when the event log is the source of truth. A reducer is the
-documented replay model; display code and commands should not duplicate pieces
-of that replay model.
-
----
-
-## Checklist Before Commit
-
-- [ ] Searched for existing similar code
-- [ ] No copy-pasted logic that should be shared
-- [ ] No repeated untyped payload field extraction outside a shared decoder
-- [ ] Constants defined in one place
-- [ ] Similar patterns follow same structure
-- [ ] Reducer/action transitions live in one reducer or command dispatcher

-## Gotcha: Python if/elif/else Exhaustive Check
-
-**Problem**: Python's if/elif/else chains have no compile-time exhaustive check. When you add a new value to a `Literal` type (e.g., `Platform`), existing if/elif/else chains silently fall through to `else` with wrong defaults.
-
-**Symptom**: New platform works partially — some methods return Claude defaults instead of platform-specific values. No error is raised.
-
-**Example** (`cli_adapter.py`):
-```python
-# BAD: "gemini" falls through to else, returns "claude"
-@property
-def cli_name(self) -> str:
-    if self.platform == "opencode":
-        return "opencode"
-    else:
-        return "claude"  # gemini silently gets "claude"!
-
-# GOOD: explicit branch for every platform
-@property
-def cli_name(self) -> str:
-    if self.platform == "opencode":
-        return "opencode"
-    elif self.platform == "gemini":
-        return "gemini"
-    else:
-        return "claude"
-```

-**Prevention**: When adding a new value to a Python `Literal` type, search for ALL if/elif/else chains that switch on that type and add explicit branches. Don't rely on `else` being correct for new values.
-
----
-
-## Gotcha: Asymmetric Mechanisms Producing Same Output
-
-**Problem**: When two different mechanisms must produce the same file set (e.g., recursive directory copy for init vs. manual `files.set()` for update), structural changes (renaming, moving, adding subdirectories) only propagate through the automatic mechanism. The manual one silently drifts.
-
-**Symptom**: Init works perfectly, but update creates files at wrong paths or misses files entirely.
-
-**Prevention**:
-- **Best**: Eliminate the asymmetry — have the manual path call the automatic one (e.g., `collectTemplateFiles()` calls `getAllScripts()` instead of maintaining its own list)
-- **If asymmetry is unavoidable**: Add a regression test that compares outputs from both mechanisms
-- When migrating directory structures, search for ALL code paths that reference the old structure
-
-**Real example**: `trellis update` had a manual `files.set()` list for 11 scripts that `getAllScripts()` already tracked. Fix: replaced the manual list with a `for..of getAllScripts()` loop. See `update.ts` refactor in v0.4.0-beta.3.
-
----
-
-## Template File Registration (Trellis-specific)
-
-When adding new files to `src/templates/trellis/scripts/`:
-
-**Single registration point**: `src/templates/trellis/index.ts`
-
-1. Add `export const xxxScript = readTemplate("scripts/path/file.py");`
-2. Add to `getAllScripts()` Map
-
-That's it. `commands/update.ts` uses `getAllScripts()` directly — no manual sync needed.
-
-**Why this matters**: Without registration in `getAllScripts()`, `trellis update` won't sync the file to user projects. Bug fixes and features won't propagate.
-
-**History**: Before v0.4.0-beta.3, `update.ts` had its own hand-maintained file list that frequently fell out of sync with `getAllScripts()`. This caused 11 Python files to be silently skipped during `trellis update`. The fix was to eliminate the duplicate list and use `getAllScripts()` as the single source of truth.
-
-### Quick Checklist for New Scripts
-
-```bash
-# After adding a new .py file, verify it's in getAllScripts():
-grep -l "newFileName" src/templates/trellis/index.ts  # Should match
-```
-
-### Template Sync Convention
-
-`.trellis/scripts/` (dogfooded) and `packages/cli/src/templates/trellis/scripts/` (template) must stay identical. After editing `.trellis/scripts/`, always sync:
-
-```bash
-rsync -av --delete --exclude='__pycache__' .trellis/scripts/ packages/cli/src/templates/trellis/scripts/
-```
-
-**Gotcha**: Running rsync with wrong source/destination paths can create nested garbage directories (e.g., `.trellis/scripts/packages/cli/...`). Always double-check paths before running.

+## 结论速览
+
+> [!IMPORTANT]
+> OCI Portal 的每次 API Key 请求都会在签名的 `keyId` 中携带
+> `tenancy OCID / user OCID / fingerprint`。这能准确识别云身份，但不能单凭
+> 一次请求证明调用方是 OCI Portal。
+
+| 问题 | 结论 |
+| --- | --- |
+| Oracle 能识别单次请求的租户和用户吗？ | **能。**签名身份、源 IP、目标服务、操作与时间均可见 |
+| 通用 SDK 请求头能识别 OCI Portal 吗？ | **不能。**默认 User-Agent、签名算法和 Go TLS 特征被大量客户端共享 |
+| Oracle 能关联多个租户共用同一实例吗？ | **具备能力。**需组合出口 IP、资源元数据、固定文本和调用序列 |
+| 外部第三方能完成同等关联吗？ | **通常不能。**其无法取得 Oracle 网关日志和租户内部资源元数据 |
+
+<a id="request-signals"></a>
+
+## 单次请求暴露面
+
+当前项目统一通过 `common.NewRawConfigurationProvider` 使用 API Key：
+
+```text
+Authorization: Signature version="1",
+  keyId="<tenancyOCID>/<userOCID>/<fingerprint>",
+  algorithm="rsa-sha256", ...
+```
+
+| 信号 | 默认形态 | 区分度 |
+| --- | --- | :---: |
+| 签名身份 | `tenancy / user / fingerprint` 明文位于 `keyId` | 身份强，软件弱 |
+| User-Agent | 大多数 SDK 请求为 `Oracle-GoSDK/<版本> (...)` | 弱 |
+| SDK 客户端信息 | SDK 生成的服务请求通常带 `opc-client-info: Oracle-GoSDK/<版本>` | 弱 |
+| 请求元数据 | `Date`、`Host`、`request-target`；写请求另含 body 摘要 | 通用 |
+| 网络特征 | 源 IP、TLS / ALPN、HTTP/2 行为 | 单次弱，跨租户组合后增强 |
+| OCI 遥测头 | 显式启用 `OCI_INCLUDE_REQUEST_TELEMETRY_DATA=true` 时，SDK 操作可写 service / operation；直通请求未必携带 | 可选 |
+
+项目没有构造 Instance Principal、Resource Principal 或 Session Token
+鉴权，也没有主动覆盖 User-Agent 或为 `opc-request-id` 设置固定前缀。
+`opc-client-info` 由 SDK 请求构造器写入，不含 OCI Portal 标记；手工构造的
+请求可能不带该字段。少量手工签名请求绕过 `BaseClient.prepareRequest`，
+使用 Go `net/http` 的默认 User-Agent。
+
+<a id="portal-signals"></a>
+
+## OCI Portal 增量指纹
+
+| 信号 | 当前行为 | 关联强度 |
+| --- | --- | :---: |
+| 出口 IP | 无租户级或全局代理时，走部署环境默认出口 / NAT | **强旁证（命中时）** |
+| 日志回传资源名 | 按 tenancy 派生为 `<8hex>-audit*`，描述使用中性文案 | 弱 |
+| GenAI Responses 请求头 | 同时写入 `CompartmentId` 与 `opc-compartment-id` | 中 / 弱 |
+| API 调用序列 | 测活、账户画像、区域与资源查询存在稳定组合 | 辅助 |
+
+SDK 默认 User-Agent、`opc-client-info` 与固定签名格式只说明“使用 OCI Go
+SDK”，不是项目专属信号。
+
+<a id="assessment"></a>
+
+## 多租户关联评估
+
+| 观察视角 | 结论 | 主要依据 |
+| --- | --- | --- |
+| Oracle 内部，跨租户数据 | **中** | 固定文本、出口 IP 与调用序列可组合比对 |
+| Oracle 内部，单租户数据 | **低** | 能识别实现痕迹，但难证明多个租户共用同一实例 |
+| 仅看 SDK 请求头 | **低** | 可识别云身份和 SDK 类型，不能可靠识别具体应用 |
+| 外部第三方 | **通常不可行** | 缺少 OCI 网关日志、Sign-on Policy 与租户资源元数据 |
+
+这些等级表达的是“可关联性”，不是 Oracle 已执行关联或据此采取处置。
+同一出口 IP 也可能来自 NAT、代理或共享基础设施，必须与其他信号联合判断。
