Suggested reviewers: Merge Risk: ⚪ Minimal · up to The feature records local Trending history once per day and shows rank changes. Earlier concerns were about time-zone day grouping, invalid dates, a time-zone-dependent test, and stale lists being saved under the wrong filter. All of these are fixed in the current code, and no outstanding issue remains that would block merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

In `@src/components/DiscoveryView.tsx`:
- Around line 521-525: Update the DiscoveryView flow around
useTrendingSnapshotCapture so snapshots are captured only after a successful
response has replaced allRepos, or only when the list’s stored period and
language match trendingTimeRange and discoveryLanguage. Prevent stale results
from the previous query from being written into the new trending filter bucket.
In `@src/utils/trendingSnapshots.ts`:
- Around line 22-24: Update dayKey and dayNumber to derive the calendar date
from a Date’s local year, month, and day rather than slicing or
timestamp-dividing the ISO value. Build dayKey from those local components and
compute dayNumber with Date.UTC(localYear, localMonth, localDay), preserving
stable day sequencing across daylight-saving transitions.
- Around line 54-56: Update toTimestamp to validate the ISO year-month-day
prefix and reject impossible calendar dates, including invalid month lengths and
non-leap-year February 29, before calling Date.parse. Keep
normalizeTrendingSnapshot’s existing null handling and timestamp conversion
unchanged for valid values.

@Khk-NL 感谢这个 PR！CodeRabbit 识别出 3 个待修复的问题：
请参考上述评论逐条修复。 |
开发守则 §7 的第一刀：Trending 从"即时展示"变成可对比的本地历史。 - src/types/trendingSnapshot.ts（新）+ src/utils/trendingSnapshots.ts（新）: 纯函数。 按「周期 × 语言 × 自然日」去重（同一天刷新多次只保留最后一份，避免用户每次刷新都看到 "上升 N 名"的假象）；每个桶最多 30 份、超过 90 天的快照在写入时清掉。 `buildTrendingHistory` 给出当前名次、上一天名次、名次变化、首次上榜时间、连续上榜天数， 以及自首次记录以来的 star 增量。`pickTrendingHighlights` 挑出上升/下降/新上榜各若干。 - store: trendingSnapshots 进唯一持久化 Store（版本 16→17）；normalizer 与 migrate 共用同一份 校验，坏快照与超期记录在迁移时就被丢弃。 - useTrendingSnapshotCapture: 只在 trending 频道把当前可见榜单记成快照；接口没给 rank 时用 当前顺序兜底。记录本身受 store 侧去重与上限约束。 - TrendingHistoryPanel: 榜单上方的一小块「榜单变化」。**只有一份快照时不渲染**——那时所有 条目都会被算成"新上榜"，没有信息量。 - 口径写在界面上：名次变化标注"与上一天的本地记录相比"；star 增量写成"自首次记录新增 N stars"，不冒充 GitHub 的"本周期新增"。 - 8 个新 key 十种语言一次补齐。 未做（留给后续）：当前平台兼容资产 / Installable only / Not starred / Not seen / Active only 这些筛选（依赖资产识别与最近浏览两个分支先合并），以及批量选中送入导入工作台。

Fixed in 97068f9: snapshots are captured only after a successful refresh marker changes, calendar grouping uses the user local day, and impossible ISO calendar dates are rejected. Focused tests, typecheck, and lint pass. |

Inline comments:
In `@src/components/DiscoveryView.tsx`:
- Around line 520-529: Update the useTrendingSnapshotCapture call in
DiscoveryView to pass only the trending repository list and trending channel’s
refresh timestamp, rather than the currently selected channel’s values. In
src/components/DiscoveryView.tsx lines 520–529, use discoveryRepos?.trending
with an empty-list fallback and discoveryLastRefresh?.trending with a null
fallback; in src/features/discovery/hooks/useTrendingSnapshotCapture.ts lines
20–25, no direct change is requested.
In `@src/utils/trendingSnapshots.test.ts`:
- Around line 17-18: Update the test clock constant NOW in the trending snapshot
tests to use local noon rather than a fixed UTC timestamp, so the one-hour
offset stays within the same local calendar day across time zones.

@Khk-NL 审计未修，且存在冲突。 |
# Conflicts: # src/store/normalizers/persistedState.ts # src/store/schema.ts # src/store/types.ts # src/store/useAppStore.modularization.test.ts
|
已修复这两条审查问题，并将目标仓库当前 main 合入本分支解决冲突。Trending 历史现在只记录 Trending 频道的结果和刷新时间，按实际使用的平台筛选分组；相关测试、类型检查、lint、i18n 和项目门禁均已通过。后续新需求会先开 issue 对齐范围，并按一个 PR 完成后再提下一个。 |
Summary
The panel deliberately describes these values as local observations rather than GitHub's official period metrics.
