Deployment Notes (maintainer actions after merge)

Cloud-first order — the new CLI session-state contract must not reach production before the pieces that understand it:

  1. Session-state migration — apply migrations/20260817120000_account-session-states.sql:
    • creates tokentracker_account_session_states: canonical cloud truth for trae-cn at the SESSION level. Identity is (user_id, source, session_id)device_id is NOT identity (the usage API request carries no device discriminator). Session-id evidence split (2026-08-17, one account, three real fetches 137→141→164): repeated-fetch stability VERIFIED (137/137 persisted, corrections KEPT ids), cross-window stability VERIFIED (exact subsets), no duplicate ids OBSERVED. Cross-device same-account id stability is NOT DIRECTLY VERIFIED: no device discriminator in the request body is necessary but not sufficient (a device/login context could ride inside the JWT / server auth context), and no second independent device/auth experiment was run. If it were ever DISPROVEN (same logical session, different ids per device), this PK would split one logical session into competing rows and the identity must be re-evaluated.
    • defines tokentracker_upsert_account_session_states(): batch whole-row replace with a STRICT LWW guard (EXCLUDED.snapshot_verified_at > t.snapshot_verified_at), so the three correction classes collapse into ONE operation — downward S 100→60, model S A→B, bucket S 10:00→10:30 — and transport retries are idempotent (a replay applies nothing). Absence is NOT PROVEN to mean deletion: nothing ever deletes a session row (no DELETE path exists),
    • replaces leaderboard_hourly_dedup_v2: trae-cn now aggregates from session states (one row per session; corrections already reflected), cursor keeps the legacy whole-row MAX dedup (identical rows across devices, no session identity),
    • snapshot_verified_at is the CLIENT logical fetch stamp (the API exposes no provider-side ordering signal — headers carry only CDN trace ids, rows carry no revision; probed 2026-08-17). Best-effort cross-device ordering under clock skew, a documented residual risk — NOT strict correctness.
      Safe to apply first: with an empty session-state table the trae-cn aggregation branch returns nothing, and trae-cn has never been served from the cloud before this PR, so pre-CLI behavior is unchanged.
  2. Account usage grouped RPC — re-run the updated scripts/ops/account-usage-grouped-rpc.sql (trae-cn branch aggregates from tokentracker_account_session_states; requires step 1).
  3. Ingest edge — deploy the updated dashboard/edge-patches/tokentracker-ingest.ts (validates and batch-upserts account_session_states via the LWW RPC, last-wins per session within a batch; malformed states fail closed 400). Requires step 1 (the RPC function) and must precede the CLI release, otherwise session states sent by the new CLI are dropped by the old edge.
  4. Leaderboard / profile / devices edges — deploy dashboard/edge-patches/tokentracker-leaderboard-profile.ts and dashboard/edge-patches/tokentracker-account-devices.ts (account-source classification from this PR).
  5. Historical rollup — this migration also SUPERSEDES leaderboard_rollup_daily_advance_v2 with first-seed gap prioritization. Without it, a new account's first ~30-day TRAE seed (all CLOSED days) shows immediately on account/profile/bounded boards but is UNDERCOUNTED on the leaderboard TOTAL (materialized rollup ∪ live tail; the tail only covers today) until the plain cyclic repair reached the seed days — up to a full cycle. The updated function detects the earliest closed day that has trae-cn session states but no trae-cn rollup row and jumps the same bounded 7-day repair window there: a first seed heals deterministically in ceil(seed_span / 7) scheduled total refreshes (30-day seed = 5 runs ≈ 30h at the ~6h cadence). Corrections to already-covered days (stale values, row exists) are NOT gaps and keep the ordinary cyclic schedule — that lag scales with TOTAL history length. An immediate rebuild (leaderboard_rollup_daily_replace_v2 for the affected range) remains available for instant parity but is NOT required for eventual consistency. Regression: test/leaderboard-rollup-correction.test.js scenarios A–D (downward / model migration / cross-day bucket migration / first 30-day seed through the real rollup semantics + SQL contract pins, including the pre-fix undercount).
  6. Smoke checks — account total = profile total = bounded leaderboard week/month hold IMMEDIATELY after a trae-cn first sync; leaderboard TOTAL reaches parity after the seed backfill completes (≤ ceil(seed_span/7) scheduled total refreshes, ~30h for a 30-day seed) — or instantly if step-5's manual replace_v2 was run over the seed range. Verify a revoked/stale device no longer contributes. Optional deep check: sync two devices of one account where TRAE revised a session (bucket/model/downward) and confirm the account totals follow the newest observation exactly once.
  7. CLI release — publish the CLI build that emits account_session_state queue records after the bucket rows.

Dependency DAG: 1 → 2; 1 → 3; 1 → 5; 4 independent; 6 after 1–4; 7 after 1 + 3.

Note: the earlier review iteration of this PR used a first_covered_hour watermark scheme; that migration was never deployed and has been fully replaced by the session-state design above (the watermark table no longer exists in this PR).

📝 Walkthrough

Walkthrough

TRAE Work CN support adds local credential handling, authenticated usage retrieval, incremental parsing, account-level aggregation, synchronization, provider metadata, dashboard surfaces, privacy documentation, and validation. Public documentation now reports 32 supported tools.

Changes

TRAE Work CN integration

Layer / File(s) Summary
Authentication and usage API
src/lib/trae-cn-config.js, test/trae-cn-config.test.js
Adds credential discovery, tc v5 decryption, JWT extraction, paginated requests, validation, timeouts, and authentication retry handling.
Incremental parsing and synchronization
src/lib/rollout.js, src/commands/sync.js, test/trae-cn-parser.test.js, test/sync-trae-cn.test.js
Adds rolling 30-day synchronization, session reconciliation, cursor persistence, progress reporting, idempotency, and failure isolation.
Account-level aggregation
src/lib/source-metadata.js, scripts/ops/*, dashboard/edge-patches/*, test/source-metadata.test.js
Classifies trae-cn as an account-level source and applies cross-device aggregation.
Provider and documentation surfaces
dashboard/src/*, dashboard/index.html, README*, docs/PRIVACY.md, src/commands/init.js, package.json
Adds provider names, icons, logos, onboarding text, privacy disclosures, and 32-tool metadata.
Discovery validation
test/discovery-metadata.test.js
Updates provider-count assertions and verifies TRAE Work CN across discovery surfaces.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to a5505

This change adds TRAE Work CN usage synchronization and dashboard support, but the current implementation can record no usage for accounts with more than roughly 2,000 sessions because of a pagination limit; the dashboard fallback label also needs localization follow-up. Merge should wait for the pagination issue to be fixed or explicitly accepted by the owner.

93-93: 🗄️ Data Integrity & Integration | 🔵 Trivial

Sequence the rollout so device rows and account rows agree.

trae-cn usage is account level only after this RPC is redeployed. Clients begin uploading trae-cn rows as soon as the CLI ships. Until the RPC and the edge functions carry the same list, the same account-wide totals are attributed per device and summed across devices.

Apply this RPC and scripts/ops/leaderboard-usage-grouped-rpc.sql, then redeploy dashboard/edge-patches/tokentracker-account-devices.ts and dashboard/edge-patches/tokentracker-leaderboard-profile.ts, before the CLI release that emits trae-cn rows. Also confirm whether the 30-second Postgres cache mentioned in the edge patches must be invalidated after the change.

src/lib/rollout.js (1)

16622-16627: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

cursors.traeCn.sessions grows without bound.

The parser only adds session entries. It never removes them. The sync fetches a rolling 30-day window, so a session older than 30 days never appears in a payload again, but its entry stays in cursors.json forever.

Two effects accumulate:

  1. cursors.json grows by one entry per session for the lifetime of the install.
  2. This loop revalidates every stored entry on every sync, so validation cost grows with total history rather than with the fetched window.

The Droid parser solves the same problem with a prune option in src/commands/sync.js (Line 1551). Consider pruning entries whose bucketStart falls before the fetched window start.

Inline comments:
In `@dashboard/src/lib/provider-display.js`:
- Line 9: Replace the hardcoded “TRAE Work CN” value in the provider display
mapping with a new key from copy.csv, then resolve that key through the existing
copy() path; add the corresponding user-facing text entry to
dashboard/src/content/copy.csv.

Apply the same fix in `@dashboard/src/ui/marketing/agent-logos.js` at line 36: The
same hardcoded user-facing label appears in marketing logo metadata.

In `@README.de.md`:
- Line 54: Update the privacy wording near the local-first statement to
accurately describe when the read-only TRAE Work CN usage request is made,
matching the default sync behavior documented in docs/PRIVACY.md; if the request
is configurable, state its opt-in requirement and disable control instead of
labeling it optional without conditions.

In `@README.ja.md`:
- Line 198: Complete the localized provider documentation by adding Reasonix and
DeepSeek Harness to both the supported-tools table and passive-reader FAQ in
README.ja.md (lines 198-198) and README.ko.md (lines 198-198), keeping the
entries consistent with the existing provider guidance.

In `@src/commands/sync.js`:
- Around line 1696-1709: Update the TRAE CN usage fetch flow around
fetchTraeCnUsageWithAuth to avoid permanently skipping heavy accounts when the
default pagination limit is exceeded and to reduce unnecessary synchronous
latency. Use a supported larger page size, a narrower or incremental time
window, or cursor-based fetching so pagination scales with new sessions while
preserving complete usage collection.
- Around line 1690-1694: Update the Trae Work CN sync condition around
resolveTraeCnStoragePath to require that the resolved storage.json path exists
via existsSync before entering the branch. Preserve the existing
lightweight-sync and sourceAllowed checks, and keep fetchTraeCnUsageWithAuth
unreachable when the credentials file is absent.

In `@src/lib/trae-cn-config.js`:
- Around line 276-311: Move the clearTimeout(timer) cleanup in the usage API
request flow so it runs only after response.json() completes, keeping the same
timer and controller.signal active through body consumption. Preserve the
existing fetch and JSON error handling while ensuring both fetch failures and
body-read completion still release the timer.

In `@test/discovery-metadata.test.js`:
- Around line 28-30: Update the localized README validation test around the
existing provider assertions to verify every canonical provider name, including
Reasonix and DeepSeek Harness, for each file under test. Preserve the current
count and rate-limit checks while ensuring no localized README can pass with an
incomplete provider set.

Two follow-ups on the review feedback:

CodeQL js/file-data-to-network (medium) — this one is by design and I'd like to request a dismiss (GitHub code scanning doesn't honor inline suppression comments): the locally stored TRAE CN JWT is read from TRAE's own storage.json and sent only to the fixed official endpoint https://api.trae.cn/... — that round-trip is exactly how this provider works. The token is never logged, never persisted elsewhere, and transport errors are sanitized so it can't leak through error messages.

High-capacity pagination (>2,000 sessions / 30 days) — implemented in f1bd60fc. A read-only probe against the official API confirmed the window semantics first:

  • [start_time, end_time] is closed on both ends ([a,b] and [b,c] both return the row at b)
  • a row returned by two overlapping windows is byte-identical — an idempotent duplicate, never cumulative
  • staggered sub-windows ([start, mid] + [mid+1, end]) union back to exactly the full window (verified row-by-row and token-conserving)

Based on that evidence, an over-capacity window now splits recursively into staggered halves, bounded by a split-depth ceiling of 8 (finest sub-window ≈ 2.8h, aggregate ceiling ≈ 512k sessions/30d). A window still over capacity at that granularity keeps failing closed, so the never-a-partial-import guarantee is preserved.

看完整个 PR。先说好的:parser 的对账式设计(per-session 记录上次贡献、修正时先减旧桶再加新桶)是正确解法;去重 fail-closed;测试真的走到断言路径;31→32 的计数同步做得很完整(5 个 README、index.html、llms.txt、init.js、agent-logos 全对上,discovery 测试还被加强成全量校验)。工艺没问题,问题集中在三块需要维护者拍板的地盘上。

先决条件(不满足则不进入下一轮 review):

B3. input_token 语义零证据。 normalizeTraeCnSession 假定 input_token 不含 cached,但全部 fixture 都是手造合成数据,没有一份脱敏真实响应,也没有与 TRAE 官方用量页的对账。Codex / Copilot / Qoder 的 input 都含 cached,照抄相加虚高 6–7 倍,这是接新 provider 的硬门槛。请补:一份脱敏原始 API 响应 + 与 TRAE 后台用量数字的总额对账(差异 <1%)。

Blocking:

B1. 账户级来源清单漏了第五处,恰好是线上生效的那个。 scripts/ops/leaderboard-rollup-daily.sqlARRAY['cursor']::text[] 未同步——它头部注释写明 supersedes leaderboard-usage-grouped-rpc.sql,是 leaderboard_hourly_dedup() 的现行定义。你同步的 4 处正好是 account-source-parity.test.js 的全部覆盖范围,所以 CI 绿是 parity 测试自身的盲区。后果:trae-cn 落进 machine-level 分支,吊销过设备的用户在排行榜与 profile 之间数字对不上。修法:补该文件 + 把它加进 parity 测试,别让下一个人再踩。

B2. 撤回对 leaderboard-usage-grouped-rpc.sql 的改动。 该文件头注释写着 re-apply 会把 #263 的修复回滚回超时的 full-scan 版本,只作 rollback reference 保留。改一个废弃定义有害无益。同时 PR 需要补部署清单:哪些 RPC 手动执行、哪些 edge 部署、什么顺序——这些是合并后的运维动作,清单必须由 PR 提供。

必改(证据通过后):

S1. JWT 外发必须做成默认关闭的 opt-in。 现在任何前台 sync(serve 启动、dashboard 刷新、--drain)都会拿解密出的 JWT 请求 api.trae.cn,项目里没有 per-source 关闭机制,用户想退出只能登出 TRAE。这是本项目第一个定期外发凭据的数据源,性质和 Limits 面板可见时才发的额度请求不同。加 settings/env 开关,默认关闭。

S3. 单行异常不能整批放弃。 测试断言缺 cache 字段必须抛错,但 TRAE CN 主力豆包/DeepSeek 没有 prompt cache 概念,API 很可能对部分行不返回 cache_read_token——一旦出现整个 payload 抛错,而 warnProviderParseFailure 在 auto 路径第一行就 return,用户永远看不到数据也看不到提示。改成 per-row 隔离(坏行跳过并计数),auto 路径留可诊断痕迹。

S5. 按 CLAUDE.md 要求接 src/commands/status.js(检测状态、storage 路径、auth 可读性),叠加 S3 的静默失败,现在完全不可诊断。

S6. 回退 README 头条改动。 100% local — no network callsLocal-first + TRAE 专属 blockquote 属产品定位决策,不在功能 PR 范围。TRAE 说明保留在支持表格行内即可,PRIVACY.md 的补充说明可以留。

Follow-up 可以后置,但 S4 建议本 PR 一并做: cursors.traeCn.sessions 无上限增长且每次 sync 全量校验,需按窗口起点做单调 prune(watermark 与窗口起点绑定,否则清掉的 session 重现会双算)。S2(30 天全量拉取在 sync 锁内,重度用户 45s+,建议 last-fetch 节流)、S7(无定价条目,TRAE 行成本恒 $0,补 curated 或 UI 标注订阅制)可后置。

Advisory:usage_type: [7] 魔数需注释依据;API 不返回 total 时容量分裂失效,30 天导入会在第 100 页硬抛;resolveTraeCnStoragePath 建议挪进 try 内。

另外确认一点:tc-v5 解密读的是 TRAE 自己的存储目录,没有越过凭据边界红线,这个方案本身可以接受;但硬编码逆向 key 意味着 TRAE 换 key 整块失效,请在代码注释里写明 key 来源与失效表现,方便日后排查。

修正 B1 的口径:leaderboard-rollup-daily.sql 是维护者侧的运维文件,不在仓库里(scripts/ops/* 整体 gitignore),你无法直接改它,parity 测试也不应引用一个仓库里不存在的文件——这两点收回。

B1 的实质不变但责任归属变了:第五处 account-level source 清单硬编码在线上函数 leaderboard_hourly_dedup_v2 里,由维护者在部署时同步。对你的要求改为:在 B2 要求的部署清单里加一节「account-level source 变更的云端影响」,写明 trae-cn 作为 account-level source 需要:1) 线上 leaderboard_hourly_dedup_v2account_sources 数组同步;2) 历史 rollup(tokentracker_leaderboard_rollup_daily_v2)按旧分类聚合过,需全环重生成才能让历史数据按新分类去重——这两步都是维护者动作,但清单必须由 PR 说明,漏掉任何一步多设备用户的 trae-cn 数字就会错。

其余条目(先决条件 B3、B2 撤回 SUPERSEDED 文件改动、S1–S6)不变。

- B2: 撤回对 SUPERSEDED rollback reference (leaderboard-usage-grouped-rpc.sql) 的改动
- B3: input_token 语义修正为 cache-inclusive(积分账单零残差回归证实),按 Qoder 约定剥离 cached 子集,total = input_token + output_token
- S1: JWT 外发改为默认关闭的 opt-in 开关 TOKENTRACKER_TRAE_CN_USAGE
- S3: 单行异常 per-row 隔离并计数,cache 字段缺失视为 0,auto 路径 stderr 输出跳过行数
- S4: cursors.traeCn.sessions 按窗口起点单调 prune,防无上限增长
- S5: status 命令接入 TRAE CN 检测(storage 路径 / auth 可读性 / opt-in 状态)
- S6: 回退 5 语言 README 头条,保留支持表格行与 PRIVACY.md 说明
- 图标改为官方 app 图标样式(白色圆角方 + 黑色面具图形,两个菱形眼),
  从 work.trae.cn 官方 PWA 图标逐像素复刻,固定黑白配色适配深浅主题
- zh/zh-TW 显示名统一为品牌名 TRAE Work CN(与其他语言及 copy.csv 一致)

感谢详细的 review,全部意见已处理完毕(d93f9ab7 + 2b4abc7),逐条回应:

B3(先决条件)— input_token 语义证据与修正

TRAE CN 官方用量页只显示按消息的积分明细,没有 token 汇总,无法直接对账 token 总量,因此改用积分定价结构法对账。结论:input_token 是 cache-inclusive(与 Codex / Copilot / Qoder 一致),最初的互斥假设是错的,已修正映射。

三重证据(真实账户 30 天窗口、145 个会话行):

  1. 零残差定价回归:用每行官方 credits_float 对 token 做线性回归,DeepSeek-V4-Flash(38 行)与 GLM-5.2(24 行)均 R²=1.000000、maxErr=0.00,解出统一定价 credits = 112×(input−cache_read)/M + 28×cache_read/M + 392×output/M。回归式中 cache_read 系数为负(−84)只有在包含口径下才自洽(cached 计 1/4 价);若按互斥口径解释,意味着缓存 token 价格为负,不可能。
  2. 比值硬下界:135/135 个含 cache 的行都满足 input ≥ cache_read,且最小值恰好为 1.000(全命中行:整段上下文都来自缓存)。互斥口径下的 agent 会话必然大量出现 cache_read ≫ input,一次都不会出现。
  3. session 累计锚点:从官方用量页 UI 直接读取某会话两个时点的积分值(10.59、33.03),与 API 同 session 行的 credits_float(10.5900、33.0344)精确吻合——UI 显示的是 session 累计值;两个增量区间用同一公式预测 4.1470 vs 实际 4.1468,千分位吻合。

修正内容(normalizeTraeCnSession,按 Qoder 约定):input_tokens = input_token − cache_read − cache_write(裸输入余量),cached_input_tokens / cache_creation_input_tokens 为剥离出的子集(钳制在 input 内,buckets 恒可加回 input_token),total_tokens = input_token + output_token。30 天总量从虚报 ~287M 修正为 152.2M。

端到端实测(隔离 HOME + 真实账户 opt-in 拉取):145 行 / 0 skipped / 38 桶,同 payload 重放幂等。实测与本机使用记录一致——模型清单与 TRAE 客户端用量页吻合(GLM-5.3 / DeepSeek-V4-Flash / GLM-5.2),积分账单经定价公式逐行零残差闭合:

trae-cn-sync-verification

B2 已撤回对 leaderboard-usage-grouped-rpc.sql(SUPERSEDED rollback reference)的改动,保留原状;部署清单已补到 PR 描述。

B1 leaderboard-rollup-daily.sql 不在本仓库。线上 leaderboard_hourly_dedup_v2account_sources 数组同步、以及 rollup_daily_v2 历史重生成,均已写入 PR 描述的 Deployment Notes(含执行顺序)。

S1 新增环境变量 TOKENTRACKER_TRAE_CN_USAGE,默认关闭:未设置时不发任何请求、不读 auth 存储(有测试断言零请求)。

S3 改为 per-row 隔离:畸形行跳过并计数(skippedRows),cache 字段缺失视为 0(豆包/DeepSeek 无 prompt cache 概念),仅当全部行畸形时才抛错;auto 路径 stderr 输出 TRAE Work CN sync: skipped N malformed session row(s)

S4 已实现:cursors.traeCn.sessions 按窗口起点单调 prune(复用 kiroCli 的 watermark 模式,含 +30min bucket 边界;窗口回退时 watermark 不回退,防止清掉的 session 双算)。

S5 status 已接入:输出 storage 路径、auth 可读性、opt-in 状态三行诊断。

S6 已回退 5 语言 README 头条改动(保留支持表格行 + PRIVACY.md 补充说明)。

Advisory 均已处理:usage_type: [7] 来源注释;maxPages 耗尽也抛 capacity code(total 缺失时时间窗拆分仍生效,有测试);逆向 key 失效签名注释;traeCnStoragePath 已在 try 块内解析。

另附两处品牌化修正:显示名统一为 "TRAE Work CN"(zh/zh-TW 与其他语言对齐);ProviderIcon 换成官方 app 图标样式(自 work.trae.cn PWA 图标逐像素复刻,白底圆角方 + 黑色面具图形,固定黑白配色适配深浅主题)。

- 将 ProviderIcon 的 TraeCnIcon 从 深色渐变底+白色对称括号
- 改为 work.trae.cn 官方 favicon / PWA icon-512.png 风格:
  白底圆角方形 (rx=76, 512px 画布) + 纯黑括号形
  (顶部横条 + 双臂 + 双纺锤装饰),像素级逆向几何一致
- 验证:vitest ProviderIcon.test.jsx 11/11 通过
       lint 0 错误 / build 成功
       localhost:7681 GUI 验收通过
- 影响文件:dashboard/src/ui/dashboard/components/ProviderIcon.jsx
跨设备去重(merge blocker):
- 每次成功的 trae-cn 同步在 queue 追加 account_sync_watermark 记录,
  声明刚对 API 验证过的闭合窗口;ingest edge upsert 到
  tokentracker_account_sync_watermarks(bucket 行之后写入,malformed 拒收)
- account_usage_grouped / leaderboard_hourly_dedup_v2 改为按小时选择
  watermark 属主设备(window_end DESC, updated_at DESC, device_id),
  只计属主设备整小时快照:向下/向上纠正、model 迁移、bucket 迁移、
  新设备首同步、双设备同快照均不再双算或残留 stale tuple
- 无 watermark 覆盖的小时(cursor / 早于验证窗口的历史)保留原
  whole-row MAX 语义;src/lib/account-usage-dedup.js 为可执行规格,
  test/account-usage-dedup.test.js 钉住 A-E 场景与 SQL/JS 一致性
- 相同窗口重复同步不重复追加 watermark(cursor 记录 lastWatermark),
  保持固定时刻幂等同步字节不变

status / robustness:
- installed 改为 storage 文件实际存在(与 sync 语义一致),
  auth 状态区分 not-signed-in / readable / malformed / unreadable
- usage API total 严格校验(非负安全整数,拒绝字符串/小数/负数),
  malformed total fail-closed,不再静默截断分页
- storage 读取区分不存在(未登录)与 IO 失败(TRAE_CN_STORAGE_UNREADABLE,
  generic 报错不泄露路径/内容)
- JWT 仅发往固定官方 HTTPS endpoint:补安全注释供 CodeQL thread 引用

其他:
- agent-logos.js TRAE 条目移除死 fallback name;补 zh「TRAE Work 中国版」/
  zh-TW「TRAE Work 中國版」译文(修复 LogoCarousel 测试与 locale 校验)
- ui-hardcode baseline 更新(ProviderIcon 官方图标品牌色 2->9)
- leaderboard_hourly_dedup_v2 的 account_sources 补 trae-cn(原先走
  machine SUM 路径会双算),parity test 纳入 migration 文件
The test built the darwin-only default storage path, so on Linux CI the
resolver returned null and installed was false. Use the env override to
point at a synthetic install; the semantics under test are unchanged.

本轮改动说明:correctness / status / robustness 修复

1. TRAE CN 跨设备 account-level 去重(merge blocker,最重要)

TRAE CN usage API 返回的是可纠正快照(session token 可上调/下调、model 可迁移、hour bucket 可迁移),原 MAX(total_tokens)(hour, source, model) 逐 tuple 取最大值的拼接方式在向下纠正、model 迁移、bucket 迁移场景必然重复统计。

方案:account_sync_watermark(同步水位线)+ per-hour canonical owner

  • 每台设备每次 TRAE CN 同步后向 queue 追加 account_sync_watermark(声明本次验证过的 [window_start, window_end)),随 hourly batch 上传并 upsert 到新表 tokentracker_account_sync_watermarks
  • 云端聚合(account-usage-grouped-rpc.sql / leaderboard_hourly_dedup_v2)对每个 (hour, source)覆盖该 hour 的最新窗口的设备为 owner,只计入 owner 行;未被覆盖的 hour 回退 legacy MAX
  • 新设备首次同步无旧 cursor 也不会残留 stale tuple:即使 payload 为空,parser 也会写 watermark,声明官方当前状态,覆盖旧设备同窗口数据
  • 幂等:cursor 记录 lastWatermark,同窗口重复 sync 不重复追加
  • parser 的 subtract-old/add-new 校正语义完整保留,未退化

2. status 安装状态误报

installed 从"能 resolve 默认路径"改为 existsSync(storage.json)(与 sync 路径一致)。auth 状态区分四态:not-signed-in / readable / malformed / unreadable

3. usage API total 严格校验(fail-closed)

total 必须是安全整数且 ≥ 0;-1 / NaN / Infinity / 小数直接抛错,不再静默截断分页。

4. auth storage 错误区分

readTraeCnAuthFromStorage 区分 ENOENT(未登录,返回 null)与 EACCES 等真实 IO 错误(抛 TRAE_CN_STORAGE_UNREADABLE,generic 消息,不泄露 JWT/storage 内容)。

安全边界(未变)

opt-in TOKENTRACKER_TRAE_CN_USAGE、JWT 仅发往固定 TRAE 官方 HTTPS endpoint、不打印/不持久化 JWT、401/403 重读 auth 最多重试一次、provider 失败隔离、pagination 超限 fail-closed、adaptive window splitting、timeout 覆盖 fetch + body parsing 均保留,并有测试守护。

新增测试

  • test/account-usage-dedup.test.js(399 行):跨设备向下纠正 / model 迁移 / bucket 迁移 / 新设备首同步 / 双设备相同快照,测试真正的聚合逻辑
  • test/trae-cn-config.test.js:malformed total 各形态、auth IO 错误分类
  • test/status.test.js:installed 三路径 + auth 四态(已改为平台无关,修掉 Linux CI 失败)
  • test/sync-trae-cn.test.js:watermark 写入 / 上传 / 幂等

部署步骤(合并后需手动执行)

  1. Supabase 执行 migrations/20260817120000_account-sync-watermarks.sql(建表 + 重建 leaderboard_hourly_dedup_v2
  2. 重跑 scripts/ops/account-usage-grouped-rpc.sql
  3. 重新部署 tokentracker-ingest / tokentracker-leaderboard-profile Edge
  4. 历史数据无需重算:watermark 表初始为空时聚合回退 legacy 行为,各设备新版首同步后平滑切换到 owner 语义

CodeQL 告警说明

"File data → outbound network request" 是本地 JWT 发送到固定 TRAE 官方 API 所致:URL 硬编码不可重定向、HTTPS、opt-in、token 不进 log / 不持久化到云端。功能预期行为,建议 dismiss。

验证:根目录 npm test 2265 tests / 0 fail;npm run ci:local 全绿;dashboard tsc + eslint + vitest 503/503 通过;远端 CI / CodeQL 全绿。

- watermark 表 PK 扩展为 (user_id, device_id, source, window_start, window_end):历史窗口不可变,30 天滚动窗口滑走后纠正仍生效
- absence 语义未证实:empty payload 纯 no-op,不发布 watermark
- 任何 malformed row 导致整个 snapshot fail-closed,不发布 authoritative watermark
- fetch start 对齐半小时边界;watermark 仅声明完全覆盖的 bucket(SQL/JS/ingest 三处语义统一)
- watermark upsert ignoreDuplicates:transport retry 不刷新 updated_at、不抢 ownership
- queue 按 (source, window_start, window_end) 保留全部历史 watermark
P0(absence 语义矛盾):
- contract 实验(trae-cn-contract-evidence-2026-08-17.json)证明从首个数据
  bucket 起窗口过滤为确定性完整枚举(E4 精确子集 82/82、E2 历史可寻址、
  E1 api_total==rows、E5 closed interval),但"首个数据点之前无返回"无法
  与 API 索引边界区分(E3 total=0 不可判定)
- watermark 新增 first_covered_hour:ownership 只覆盖
  [snapshot 首个数据 bucket, window_end)——非空 snapshot 不再对
  未见证历史做 absence 推断压零其他设备数据;该范围回退 legacy
- empty payload 不发 watermark 从特判变为同一规则的推论(无首个数据点
  → 无覆盖)

P1(同 window 双 snapshot 无法判新旧):
- watermark 新增 snapshot_verified_at:真实 fetch 时打点一次,
  append-only queue 逐字重放 → transport retry 不伪造 freshness
- owner 排序改为 window_end DESC, window_start DESC,
  snapshot_verified_at DESC, device_id:同 window 的更新真实 fetch 必胜,
  device_id 仅承担最终 deterministic tiebreak
- ingest fail-closed 校验新字段(window_start <= first_covered < window_end)
first_covered_hour watermark 无法表达 bucket migration(fresh device 的
first data bucket 无法安全 reclaim 旧 hour,10:00→10:30 双计 200)。
session identity 已 PROVEN(137/137 跨抓取稳定、修正保留 id、无重复),
canonical truth 改为 (user_id, source, session_id) 整行替换:
downward / model migration / bucket migration 收敛为同一 LWW upsert
(严格 > stamp,retry 幂等)。absence 保持 NOT PROVEN:不删除任何
session。watermark 表/逻辑退出 correctness path(migration 未部署,
直接改为最终设计,不留兼容 baggage)。R1-R6 走真实
parser→queue→LWW→聚合 链路。
…rection

1) readQueueBatch 中 account_session_state 原不计入 per-batch 记录上限,
   states-heavy 队列(fresh device 首次 30 天同步)一次读出全部(可
   >500)→ ingest 400 → offset 不前进 → 永久失败。现在 session state
   与 bucket 行计入同一上限(batchSize=200/batch,≤ edge 500 上限),
   production-path 测试(真实 readQueueBatch→drainQueueToCloud→mock
   fetch)证明:1200 states 拆多批全部送达、失败 offset 冻结、retry
   精确续传、批内无重复 session。
2) session identity 证据拆分:repeated-fetch VERIFIED / cross-window
   VERIFIED / cross-device NOT DIRECTLY VERIFIED(请求体无 device 参数
   是必要非充分条件;未做第二设备实验;如被反证需重评 PK)。
   freshness 表述去掉未实现的 skew bound。
3) >7 天 correction vs 历史 rollup:现有 advance_v2 循环 repair(每次
   6h 推 7 天、从最老历史日循环)已能更新闭环日,无需改实现;测试钉
   死 A/B/C 三场景 + SQL 契约(total=rollup∪live tail、account/profile
   实时)。migration 注释补充 lag 随总历史长度增长的特性。
首次 sync 一次 seed ~30 个闭环日 session states:account/profile/bounded
board 走实时路径立即可见,但 leaderboard TOTAL 读物化 rollup ∪ live tail
(tail 只覆盖今天),闭环 seed 日两边都不覆盖 → TOTAL 欠计整个 seed,
旧 cyclic repair 需等最多一个完整周期(history_days/7 次 run)才覆盖。

最小修复:advance_v2(在 migration 中 supersede 重定义)检测"有 trae-cn
session states 但无 trae-cn rollup 行"的最早闭环日,把 7 天 repair 窗口
跳到该处——seed 范围确定性 ceil(span/7) 次调度内重建(30 天 = 5 次
≈30h),无需等整周期。已覆盖日(仅 stale 值)不构成 gap,修正仍走
原 cyclic 调度;单次 run 工作量仍为 7 天块,不新建 invalidation 架构。

Scenario D regression:修复前 TOTAL=0 vs account=3300(欠计证明);
run 1 精确修 seed 最老 7 天(770);5 次后 TOTAL=account=3300。
SQL pin 改钉最新 advance_v2 定义(cyclic + gap 优先)。
672f02a 的 advance_v2 seed-gap NOT EXISTS 只关联 (source, day):User A
已有某日 trae-cn rollup 行时,User B 同日首次 seed 被误判"已覆盖",
拿不到 first-seed prioritized repair,退回普通 cyclic(多等最多一整
个周期)。

最小修复:NOT EXISTS 增加 r.user_id = s.user_id(rollup PK 本就以
user_id 开头,覆盖判定天然 per-user)。cyclic correction、batching、
freshness、absence、session PK 均不变。

Scenario E(可执行 regression,非仅 SQL pin):sim 改为镜像真实双表
(rollup key 加 user 维度,per-account 聚合),User A Day X 已有行 +
User B Day X 首次 seed → 修复前 minSeedGapDay()=null(bug 复现)、
TOTAL 欠计 110;修复后 Day X 仍为 gap,run 1 精确 materialize
user-b 行(220=A+B),user-a 行不变。SQL pin 钉 r.user_id = s.user_id。
