问题

通过「从链接批量 Star」添加的收藏,完成 AI 分析后再次点击同步,AI 摘要、AI 标签与分类标签会被全部清空。同步同时已把被剥离的数据写回后端,因此不可逆。

根因

这是一条 ID 错配链路:

  1. useBatchStarImport 调用 addRepository({ ...detail }),detail 自带 GitHub 真实 id(如 987654321)。
  2. 但 repositorySlice.addRepository 对新仓库丢弃了这个 id,改用合成 id Math.max(Date.now(), maxId + 1) + random(约 1.7e12)。
  3. AI 分析把 ai_summary / ai_tags / custom_category 写在那条合成 id 的记录上。
  4. 点击同步时,mergeStarredRepositories 用 GitHub 返回的真实 id 查本地记录 —— 查不到,于是整条采用裸 GitHub 数据,AI 分析与分类标签随之丢失。
  5. setRepositories + forceSyncToBackend() 把被剥离的数据写回后端。

修复

src/store/slices/repositorySlice.ts(根因)

  • 新增 resolveGitHubRepositoryId():新仓库优先沿用 GitHub 真实 id。仅当 id 非正整数、或已被另一条 full_name 的记录占用时,才退回 generateFallbackRepositoryId()(保留原有 timestamp + random 的唯一性保障)。发现页 Star 走同一函数,一并修复。
  • 顺带修复同一函数的另一处覆盖:已存在分支只回填了 custom 字段,没有回填 AI 字段。入参来自 GitHub 详情 / 发现页数据,不带这些字段,直接展开会清空已有 AI 摘要与标签。现按 repo.x ?? existing.x 回填 6 个 AI 字段(入参显式带新值时仍采用新值)。

src/features/repositories/hooks/useSearchActions.ts(存量数据自愈)

  • mergeStarredRepositories 在按 id 未命中时,增加按 full_name(大小写不敏感)兜底匹配。这让已经中招的历史数据在下次点击同步时自动恢复分析结果与分类标签,无需重跑 AI 分析。匹配上时沿用本地 id,避免改变主键、破坏后端行与 releases.repo_id 的引用关系。
  • 抽出 buildStarredRepositoryIndex() / matchStarredRepository(),并新增 countNewStarredRepositories():合并与「新增仓库计数」共用同一套匹配口径。否则被 full_name 兜底救回的存量仓库会被误报为新增,弹出错误的「发现 N 个新仓库」提示。索引用 Map 而非线性查找,避免 O(n×m)。

测试

新增 5 个回归测试,并做反向验证:临时 revert 源码后新测试全部失败,恢复后全部通过,确认测试非空转。

文件 覆盖场景
useAppStore.test.ts 沿用 GitHub 真实 id / id 冲突时退回合成 id / 重复添加时保留 AI 分析与分类
useSearchActions.test.tsx full_name 兜底保留 AI 分析 / 大小写不敏感匹配 / 计数与合并口径一致

门禁结果:tsc -b 无诊断 · eslint 0 errors · 全量 136 文件 1492 测试通过 · 生产构建通过(bundle 1094.98 KiB,限额 3000 KiB)。

影响范围

  • 仅前端 store 与同步 hook,无 schema / API / 后端改动,可安全回滚。
  • 发现页 Star 走同一 addRepository,同时受益。
  • 匹配上时保留本地 id,因此后端行与 releases.repo_id 的引用关系不变。

遗留说明

若某仓库的 AI 数据此前已被同步覆盖并从后端删除,则无法凭空恢复,需重跑一次 AI 分析 —— 这是数据已被覆写导致的,非本次代码可逆。

Summary by CodeRabbit

  • Bug 修复
    • 按仓库名称(不区分大小写)匹配时,保留已有的 AI 分析和自定义分类信息,并更新仓库描述。
    • 修正星标仓库合并与新增数量统计,避免重复匹配已有仓库或将其误判为新增。
    • 更新同一仓库时保留原有标识及本地信息;标识冲突时分配新标识,避免覆盖其他仓库。
    • 同名但实际不同的仓库会作为独立记录保存,不会继承旧仓库的分析数据;仓库改名后也能正确区分。

## 问题

通过「从链接批量 Star」添加的收藏,完成 AI 分析后再次点击同步,
AI 摘要、AI 标签与分类标签会被全部清空,且同步已写回后端,不可逆。

## 根因

这是一条 ID 错配链路:

1. `useBatchStarImport` 调用 `addRepository({ ...detail })`,`detail`
   自带 GitHub 真实 id(如 987654321)。
2. 但 `repositorySlice.addRepository` 对新仓库**丢弃**了这个 id,改用
   合成 id `Math.max(Date.now(), maxId + 1) + random`(约 1.7e12)。
3. AI 分析把 `ai_summary` / `ai_tags` / `custom_category` 写在那条
   合成 id 的记录上。
4. 点击同步时,`mergeStarredRepositories` 用 GitHub 返回的**真实 id**
   查本地记录 —— 查不到,于是整条采用裸 GitHub 数据,AI 分析与分类
   标签随之丢失。
5. `setRepositories` + `forceSyncToBackend()` 把被剥离的数据写回后端。

## 修复

**`src/store/slices/repositorySlice.ts`(根因)**

- 新增 `resolveGitHubRepositoryId()`:新仓库优先沿用 GitHub 真实 id。
  仅当 id 非正整数、或已被**另一条 full_name** 的记录占用时,才退回
  `generateFallbackRepositoryId()`(保留原有 timestamp + random 的
  唯一性保障)。发现页 Star 走同一函数,一并修复。
- 顺带修复同一函数的另一处覆盖:已存在分支只回填了 custom 字段,
  **没有回填 AI 字段**。入参来自 GitHub 详情 / 发现页数据,不带这些
  字段,直接展开会清空已有 AI 摘要与标签。现按 `repo.x ?? existing.x`
  回填 6 个 AI 字段(入参显式带新值时仍采用新值)。

**`src/features/repositories/hooks/useSearchActions.ts`(存量数据自愈)**

- `mergeStarredRepositories` 在按 id 未命中时,增加按 `full_name`
  (大小写不敏感)兜底匹配。这让**已经中招的历史数据**在下次点击同步
  时自动恢复分析结果与分类标签,无需重跑 AI 分析。匹配上时沿用本地
  id,避免改变主键、破坏后端行与 `releases.repo_id` 的引用关系。
- 抽出 `buildStarredRepositoryIndex()` / `matchStarredRepository()`,
  并新增 `countNewStarredRepositories()`:合并与「新增仓库计数」共用
  同一套匹配口径。否则被 full_name 兜底救回的存量仓库会被误报为
  新增,弹出错误的「发现 N 个新仓库」提示。索引用 Map 而非线性
  查找,避免 O(n×m)。

## 测试

新增 5 个回归测试,并做反向验证:临时 revert 源码后新测试全部失败,
恢复后全部通过,确认测试非空转。

- `useAppStore.test.ts`:沿用 GitHub 真实 id / id 冲突时退回合成 id /
  重复添加时保留 AI 分析与分类
- `useSearchActions.test.tsx`:full_name 兜底保留 AI 分析 /
  大小写不敏感匹配 / 计数与合并口径一致

全量 136 文件 1492 测试通过;`tsc -b`、`eslint`、生产构建均通过。

Merge Risk: 🟡 Moderate · up to 6c24e

Re-adding a renamed repository can create duplicate entries and save them to the backend. Match existing repositories by valid GitHub ID and update the regression test before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 6c24e

The fix preserves analysis during normal synchronization, but matching legacy records by name cannot establish that they still represent the same repository. A reused name can attach old analysis, locked classifications and subscriptions to a different repository and persist the incorrect association.

Retained concerns

  • Medium · security · inferred: The new synchronization fallback treats a matching full_name as sufficient to claim a synthetic-ID record. If a different GitHub repository reuses that name and appears in the starred list, it inherits the old local ID, analysis, locked classification and subscription state; synchronization then persists that association. The synthetic-ID threshold identifies a local key convention, not continuity of GitHub identity. Excluding real-ID records and reserving ID matches do not resolve this legacy case, and successful fallback does not record the incoming authoritative ID for later validation.
Security review details

Security Blast Radius

  • inferred — The matching exposure is bounded by eligible records in the current local repository dataset and matching names in the fetched starred list. Multiple records can be affected if multiple names are reused, and the resulting snapshot reaches the connected backend. Server-side account isolation was not inspected, so the evidence does not establish a broader tenant exposure or prove tenant containment.

Security Findings and Attack Paths

  • inferred — A repository owner able to reuse a former repository name can influence which legacy record is selected if the replacement appears in the user's starred list. Name fallback then carries old analysis, locked classification and subscription state into the replacement's metadata and persists it. This is a conditional integrity attack path, not evidence that the owner can read the user's local analysis, steal credentials or execute code.

Trust Boundaries and Controls

  • observed — The hook requires a GitHub token before reading the starred API. Backend writes use the existing authentication-header helper, which attaches the configured backend secret when present. These controls authenticate requests; neither validates that an incoming repository with the same name is the original repository represented by a synthetic local key.

Resilience and Maintainability Implications

  • inferred — Preserving the local key avoids an immediate key change for dependent state, but it also makes a mistaken name-based association persistent across retries and repeated synchronization. Retrying backend writes can preserve delivery without correcting the ownership decision; recovery therefore needs identity validation rather than transport retry alone.

Hardening Proposals

  • proposed — Separate the stable local key from a verified upstream repository identity. Preserve uncertain legacy metadata without automatically carrying trusted classifications or subscriptions across a name-only reassociation, and pin the authoritative identity after a validated repair.

Comment thread src/features/repositories/hooks/useSearchActions.ts Outdated
修复 CodeRabbit 在 #418 指出的数据完整性问题(Major)。

## 问题

上一版给 `mergeStarredRepositories` 加的 `full_name` 兜底是**单遍匹配**,
且没有占用标记。GitHub 允许新仓库复用刚改完名的旧仓库名,于是:

本地 `{ id: 1, full_name: 'owner/old', ai_summary: '...', custom_category: '工具' }`
本批输入 `{ id: 1, full_name: 'owner/new' }`(改名)与 `{ id: 2, full_name: 'owner/old' }`(复用旧名的新仓库)

- 两条输入都会命中同一条本地记录 → 产出**两条 `id: 1`** 的记录;
- 旧仓库的 AI 分析与分类被**复制到新仓库**上;
- `countNewStarredRepositories` 返回 `0` 而非 `1`;
- 错误结果随后被 `forceSyncToBackend()` 写回后端。

即修复「丢数据」的兜底本身在改名场景下会「造数据」。

## 修复

用 `assignStarredRepositories()` 取代单遍的 `matchStarredRepository()`,
改为**两遍分配**,第二遍一对一:

1. 先用 id 匹配**整批**输入,把命中的本地记录全部标记为已占用;
2. 再对剩余未匹配输入做 `full_name` 兜底,跳过已被占用的本地记录。

这样 id:1 先被占用,名称兜底只能落到真正的新增仓库上,结果也与输入顺序无关。
`mergeStarredRepositories` 与 `countNewStarredRepositories` 共用同一份分配结果,
口径一致。分配只做一次,仍是 O(n + m)。

## 测试

新增 3 个回归测试(CodeRabbit 要求的 reused-name 场景):

- 改名仓库与复用名仓库不得共用一条本地记录(id 唯一 + 不泄漏 AI 字段 + 计数为 1)
- 名称兜底结果与输入顺序无关(正序/逆序按 id 对齐后一致)
- 每条本地记录最多被分配给一条输入

反向验证:回退到单遍逻辑后 3 个新测试全部失败,恢复后全部通过。
全量 136 文件 1495 测试通过;`tsc -b`、`eslint` 通过。
修复 CodeRabbit 在 #418 安全架构评审中提出的 Retained concern(Medium · security)。
该评论发布于上一版修复之后,其中「重复选中同一条本地记录」已由两遍分配解决,
但「名称兜底不验证身份连续性」这一条仍然成立。

## 问题

上一版的 `full_name` 兜底对**所有**本地记录生效。但带真实 GitHub id 的记录,
其身份是权威的:id 对不上说明该仓库已被改名或删除。此时若旧名被另一个新仓库
复用,名称兜底会让这个新仓库继承旧仓库的 AI 分析、锁定分类与订阅状态:

本地 `{ id: 555, full_name: 'owner/old', ai_summary: '机密分析',
        custom_category: '内部工具', category_locked: true,
        subscribed_to_releases: true }`
输入 `{ id: 777, full_name: 'owner/old' }`(另一个恰好复用旧名的新仓库)

结果:新仓库错误继承全部上述状态,且被 `forceSyncToBackend()` 持久化到后端。

## 修复

按CodeRabbit 的 Hardening Proposal「要求名称兜底具备遗留来源证据」实现:

- 新增 `SYNTHETIC_REPOSITORY_ID_FLOOR = 1e11` 与 `isLegacySyntheticIdRecord()`。
  真实 GitHub 仓库 id当前量级 < 1e10,而合成 id 形如 `Date.now() + random`
  (约 1.8e12),故 `id >= 1e11` 可可靠判定为批量 Star 的历史合成 id。
- 名称兜底索引 `legacyByFullName` 只收录合成 id 记录。带真实 id 的记录不再
  参与名称兜底 —— 身份冲突交由用户显式处理,不做静默的错误归属。

这样既修复了错误归属,又保留了正��场景:合成 id 的历史记录仍能靠名称兜底
自动恢复分析结果(已有测试锁定)。

## 测试

新增 3 个测试:

- 带真实 id 的仓库,其旧名被新仓库复用时,**不得**被继承 AI 分析/锁定分类/订阅
- 合成 id 的历史记录仍能靠名称兜底恢复(正向场景不被误伤)
- 一对一分配(顺带修正此前重复的同名测试,改用合成 id)

反向验证:移除 `isLegacySyntheticIdRecord` 守卫后,安全测试失败、恢复后通过。
全量 136 文件 1497 测试通过;`tsc -b`、`eslint` 通过。

仅对同一 GitHub 身份保留 AI 字段。

发现页和批量 Star 导入在 Star 成功后调用 addRepository。当前分支只按 full_name 命中记录。当新仓库复用旧仓库名称时,repo.id 不同,但新增的 repo.ai_* ?? existing.ai_* 仍会复制旧仓库的 AI 分析。

同步逻辑已规定:真实 GitHub ID 不匹配时,名称复用表示新仓库;只有旧的合成 ID 才允许按名称兼容匹配。请在此处复用该判断。基线中已有的自定义字段保留行为不属于本次新增问题。

修复 CodeRabbit review 5366852800 指出的问题(Minor · Data Integrity)。
该问题存在于本 PR 首个提交引入的 AI 字段保留逻辑中,与上一轮修复的
同步名称兜底属于同一类身份归属缺陷,但发生在 addRepository 路径上。

## 问题

`addRepository` 的「已存在同 full_name」分支只按 `full_name` 命中记录,
却无条件沿用 `existing.ai_*`。当新仓库复用旧仓库名称时,`repo.id` 与
`existing.id` 不同,但旧仓库的 AI 分析仍会被复制过来:

本地 `{ id: 5, full_name: 'owner/old', ai_summary: '机密分析',
        ai_tags: ['机密标签'] }`
入参 `{ id: 999, full_name: 'owner/old' }`(发现页 / 批量 Star 的新仓库)

结果:新仓库错误继承旧仓库的 AI 分析。

发现页 Star 与批量 Star 导入在 Star 成功后都会调用 `addRepository`,
因此该路径同样可达。

## 修复

复用上一轮同步路径确立的判定,不另立标准:

- 把 `SYNTHETIC_REPOSITORY_ID_FLOOR` 与 `isLegacySyntheticIdRecord()` 提取到
  `repositorySlice.ts` 并导出,`useSearchActions.ts` 改为引用同一份定义,
  消除两处重复的阈值常量。
- 新增判定 `reuseExistingAI`:`existing.id === repo.id`(同一 GitHub 身份)
  或 `isLegacySyntheticIdRecord(existing)`(合成 id 历史记录,名称是唯一线索)。
  两者都不满足时,只采用入参自带的 AI 字段。
- `custom_*` 的保留属基线既有行为,按CodeRabbit 提示不作收紧。

## 测试

新增 / 修正 2 个测试:

- 复用真实 id 仓库名称的新仓库,**不得**继承其 AI 分析(反向验证:去掉守卫即失败)
- 同一 GitHub id 重复添加时仍保留 AI 分析
- 原「保留 AI 分析」测试改用合成 id,锁定合成 id 记录仍被认领的正向场景

全量 136 文件 1499 测试通过;`tsc -b`、`eslint` 通过。

修复 CodeRabbit discussion r4145277692 指出的问题(Major · Data Integrity)。
这是同一类身份归属缺陷的最后一环:上一轮只阻止了「新仓库继承旧仓库的 AI 字段」,
但记录仍被写到旧仓库的 ID 下,导致原始丢数据问题换个场景重现。

## 问题

`addRepository` 的「已存在同 full_name」分支虽然识别出了身份不同
(`reuseExistingAI === false`),却仍在下一行执行 `id: existing.id`。

本地 `{ id: 5, full_name: 'owner/old' }`,入参 `{ id: 999, full_name: 'owner/old' }`:

1. 新仓库 999 被写到本地记录 id **5** 之下;
2. 用户对新仓库做 AI 分析 → 分析结果挂在 id 5 上;
3. 下次同步,GitHub 返回真实 id **999**:`assignStarredRepositories` 按 id
   匹配不到(本地是 5),名称兜底也只认领合成 id 记录(5 是真实 id)
   → 判定为全新仓库,采用裸 GitHub 数据;
4. **分析结果再次丢失** —— 正是本 PR 要修的原始问题;
5. 若旧仓库 5 仍在星标里,新仓库的分析还会被归属到旧仓库。

即上一轮只是把「静默继承 AI 数据」降级为「静默丢失 AI 数据」,问题并未消除。

## 修复

把身份判定提升为分支条件,而不再只用于选择 AI 字段的取值:

- `isSameIdentity = existing.id === repo.id || isLegacySyntheticIdRecord(existing)`
- 同一身份 → 沿用现有分支(保留 ID、AI 分析与自定义字段)
- 身份不同 → 走新增分支,**保留原记录不动**,入参以自己的 GitHub ID
  作为独立记录加入;ID 不可用时才退回合成 id

两条路径不再共用 `existing.id`,从而保证新仓库的记录身份与其 GitHub 身份一致,
后续同步可以按 ID 正常命中。

## 测试

- 新增「复用旧名 → 独立记录」:旧记录原样保留,新仓库以 id 999 加入,
  且不继承旧仓库的 AI 分析与分类
- 新增完整链路:「复用旧名 → 独立记录 → AI 分析 → 同步仍能按 GitHub id 命中」,
  覆盖本 PR 的原始场景不会重现
- 修正上一轮遗留的测试(其断言的是旧的覆盖行为)

反向验证:去掉身份分支后 2 个新测试失败,恢复后通过。
全量 136 文件 1500 测试通过;`tsc -b`、`eslint` 通过。

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

按 GitHub ID 选择同名记录。

当批量导入预览返回 alreadyStarred: false,且 store 已包含旧真实 ID 和新真实 ID 的同名记录时,starSelected 会再次调用 addRepository。当前代码总是选中第一条同名记录。它会跳过更新分支,并追加一条新记录,导致新真实 ID 重复。后续按 ID 更新时可能只更新其中一条记录。

修复 CodeRabbit review 5367214192 指出的问题(Minor · Data Integrity)。
该问题是上一个提交(783065b,允许同名不同身份的仓库并存)引入的回归。

## 问题

上一个提交让「同名但 GitHub 身份不同」的仓库作为独立记录并存,这是正确的。
但 `addRepository` 选取待更新记录时仍用 `findIndex(r => r.full_name === ...)`,
即**永远取第一条同名记录**。

列表中已存在 `{ id: 5, full_name: 'owner/old' }` 与
`{ id: 999, full_name: 'owner/old' }` 时,再次添加 id 999:

- findIndex 命中的是 id **5** 那条;
- 身份判定不通过 ⇒ 跳过更新分支,追加一条新记录;
- 结果 store 变成 `[5, 999, 999]` —— **重复 id**;
- 后续按 ID 更新只会命中其中一条,AI 分析与分类可能写到错误的那条上。

复现:store `[5, 999]` → 再次 addRepository(999) → `[5, 999, 999]`。

## 修复

把同名记录的选取改为身份优先,取代原先的「第一条同名」:

1. `exactIdentityIndex`:`full_name` 与 `id` 都命中 ⇒ 同一 GitHub 身份,优先采用;
2. `legacySyntheticIndex`:同名且为合成 id 的历史记录(缺失权威身份,
   名称是唯一线索),仅在无精确身份匹配时兜底;
3. 都不命中 ⇒ 同名但属于另一个 GitHub 仓库,按新仓库独立新增。

这样「重复添加同一仓库」会就地更新 id 999 那条并保留其 AI 分析,
而「复用旧名的新仓库」仍然独立新增,两个场景不再互相干扰。

## 测试

新增 2 个测试:

- 已有 `[5, 999]` 同名记录时再次添加 999:不得出现重复 id,且就地更新并
  保留 AI 分析
- 无精确身份匹配时,合成 id 的历史记录仍被认领并就地更新(正向场景不误伤)

反向验证:还原为「第一条同名」查找后,新增测试与两个既有身份测试共 3 个失败。

Comment thread src/store/slices/repositorySlice.ts Outdated
修复 CodeRabbit discussion r4145581832 指出的问题(Major · Data Integrity)。
该问题由上一个提交(6c24e40)引入:选取记录时要求 full_name 与 id 同时命中。

## 问题

id 是权威身份,改名只换 full_name。但上一个提交的 `exactIdentityIndex`
要求 `full_name === repo.full_name && r.id === repo.id`:

本地 `{ id: 5, full_name: 'owner/old' }`,入参 `{ id: 5, full_name: 'owner/new' }`
(同一仓库改名)时:

- `exactIdentityIndex` 未命中(名称已变);
- `legacySyntheticIndex` 未命中(本地是真实 id,且名称不同);
- 落入新增分支,`resolveGitHubRepositoryId` 又把同一 id 判为「冲突」,
  于是生成合成 id 再插一条;
- 结果 store 变成 `[5(owner/old), 1.79e12(owner/new)]` ——
  **同一 GitHub 仓库出现两条记录**,且新记录带合成 id,
  下次同步按 id 匹配不到,又会走一遍原始丢数据链路。

复现:本地 `{id:5,'owner/old'}` + `addRepository({id:5,'owner/new'})`
→ store 出现 2 条记录。

## 修复

- 选取记录时改用**纯 id 匹配**:`hasValidGitHubId` 时 `findIndex(r => r.id === repo.id)`,
  不再要求 full_name 相同 —— 改名因此就地更新,full_name 等源字段随入参刷新。
- 相应简化 `resolveGitHubRepositoryId`:只校验 id 是否为可用正整数,
  删除「已被别的记录占用即视为冲突」的判定。该判定与「id 即身份」相矛盾,
  且在新匹配规则下已不可达 —— 命中同一 id 就是同一仓库,理应走更新分支。

“同名但身份不同”(复用旧名的新仓库)仍由 `legacySyntheticIndex` 与新增分支处理,
不受影响。

## 测试

- 原「id 冲突退回合成 id」测试断言的是错误行为,改写为
  「改名按真实 id 就地更新」:断言仅剩 1 条记录,保留真实 id、AI 分析与本地字段

反向验证:还原为 full_name+id 匹配后该测试失败,恢复后通过。
全量 136 文件 1502 测试通过;`tsc -b`、`eslint` 通过。
本 PR 前 7 轮的返工都源于同一个根源:**「id 是权威身份,full_name 仅在身份缺失时
兜底」这条规则被分散写在多处,且各处实现不一致**(有的要求 full_name 同时命中、
有的只比名称、有的大小写敏感)。每修一处就与另一处产生新矛盾,于是反复返工。

本轮按约定做针对性复审,把规则收敛到唯一实现,并修掉复审中发现的真实缺陷。

## 复审发现

扫描所有把 full_name 用于「身份判定」(而非自然键)的位置,共 4 类:

1. **`addRepository`**:与同步路径口径不一致(要求 full_name + id 同时命中)。
2. **`mergeStarredRepositories`**:规则内联在 hook 里,与 store 重复。
3. **发现页 `executeUnstar` —— 真实缺陷**:按 full_name 定位待删记录。
   本地 `{ id: 5, 'owner/old' }`(已改名/删除的旧仓库)与发现页条目
   `{ id: 999, 'owner/old' }` 同名时,删掉的是 **id 5**,而用户实际取消 Star 的
   是 999 —— 删错记录,且 999 仍留在库里。
4. **发现页 `isStarredComputed` —— 真实缺陷**:按 full_name 判断「是否已 Star」,
   同名不同身份时会把条目误判为已在库中,挡住用户的 Star 操作。

**未修改(经判定属合理用法)**:`releaseSources.ts` / `timelineSlice.ts` /
`useReleaseTimelineActions.ts` 用 `normalizeRepoKey(full_name)` 作为**发布订阅的
自然键** —— GitHub 的 release 接口本身以 owner/repo 定位,名称即该场景的身份,
不涉及「本地记录身份」判定,故保持不变。

## 改动

**新增 `src/utils/repositoryIdentity.ts`(唯一实现)**

- `SYNTHETIC_REPOSITORY_ID_FLOOR` / `isLegacySyntheticIdRecord`
- `isValidGitHubRepositoryId`
- `matchesSameGitHubId` / `matchesLegacyNameFallback`(两个判定谓词)
- `findIdentityMatch`(单条选取:id 优先,名称兜底其次)
- `assignIdentityMatches`(整批两遍分配,第二遍一对一)

**三处调用点统一改为引用该模块**

- `repositorySlice.addRepository`:改用 `findIdentityMatch`,删除本地重复定义
  与 `resolveGitHubRepositoryId`(后者仅剩 id 校验,已被
  `isValidGitHubRepositoryId` 取代)。
- `useSearchActions`:`assignStarredRepositories` 改为委托
  `assignIdentityMatches`,删除内联的两遍匹配;同时**移除对 store slice 的
  反向导入**(feature hook → store/slices 属层级倒置,改为引用 utils)。
- `useDiscoveryRepoActions`:`executeUnstar` 与 `isStarredComputed` 改用
  `findIdentityMatch`。

名称兜底统一为**大小写不敏感**(原 `addRepository` 为精确比较):GitHub 的
owner/repo 本身不区分大小写,本地缓存大小写可能与上游不一致。

## 测试

- 新增 `src/utils/repositoryIdentity.test.ts`(11 例):覆盖 id 校验、合成 id 边界、
  改名按 id 命中、名称兜底仅限合成 id、id 优先于名称兜底、整批一对一、
  入参顺序无关、真实 id 记录不被名称认领、空输入。
- 发现页:原「按 full_name 删除」测试断言的是错误行为,改写为「按 GitHub id 删除」,
  并新增「合成 id 按名称兜底删除」「同名不同身份不得删错记录」两例。

反向验证:还原发现页为 full_name 匹配后,同名误删测试失败。
全量 137 文件 1515 测试通过;`tsc -b`、`eslint`、`check:boundaries` 均通过。
