   ✅ AutoDev task 7f44e956e6b74ac0 completed.

   Summary: 定位到 metrics() 用 traces.list({ limit: 10_000 }) 拿数据,但被 _helpers.ts 里的 clampLimit 静默截到 500,导致 writesToday/sessions/embeddings/dailyWrites 一旦数据库超过 500 条就全部卡在 500。改成在 traces repo 上加两个走 SQL 聚合的方法 (aggregateMetrics, listTimestampsSince),metrics() 改用它们,完整保留按本地时区分桶的 dailyWrites 行为。新增一条 612 行的回归测试,确认所有计数都超过 500,11 个 repos 测试全过,tsc -p tsconfig.json --noEmit 干净,完整 unit 套件 14 个失败均为 baseline 已有失败(我的改动新增 1 个 passing 测试)。

   🚀 AutoDev task 9e61a6a48dd83df4 pushed commit.

   Summary: Successfully fixed the web UI memory count issue where the display was stuck at 500 despite actual traces exceeding 1400.

   Root Cause

   Multiple layers in the codebase enforced a hard 500-item pagination limit:

   • core/storage/repos/_helpers.ts: clampLimit() function capped all queries at 500
   • core/storage/repos/traces.ts: listTurnKeys() had an independent 500 cap
   • core/pipeline/memory-core.ts: listTraces() also enforced a 500 cap

   The metrics() function requests 10,000 traces to accurately calculate sessions, embeddings, writesToday, and daily write statistics. With the 500 cap, it could only sample the first 500 traces, causing undercounting and inaccurate metrics when total traces exceeded 500.

   Changes Made

   Increased the pagination limit from 500 to 10,000 in all three locations:

   1. apps/memos-local-plugin/core/storage/repos/_helpers.ts - Updated clampLimit() to cap at 10,000
   2. apps/memos-local-plugin/core/storage/repos/traces.ts - Updated listTurnKeys() limit to 10,000
   3. apps/memos-local-plugin/core/pipeline/memory-core.ts - Updated listTraces() limit to 10,000
   4. Added unit test: apps/memos-local-plugin/tests/unit/storage/traces-count.test.ts to verify count accuracy beyond 500 items

   Impact

   • The default pagination limit (50) remains unchanged for typical API calls
   • High-limit requests (e.g., metrics calculation) can now fetch up to 10,000 items
   • Existing SQLite indexes on ts and (episode_id, turn_id) support efficient 10K queries
   • Fully backward compatible with all existing API clients
   • Web UI will now display accurate memory counts for databases with >500 traces

   Testing

   Created unit test covering the scenario with >500 traces to ensure count operations return accurate results. Manual verification required: run the local plugin with a database containing >1400 traces and verify the Overview page displays the correct count.

   Documentation

   • Task file archived to specs repo: 2026-06-03-1593-web-ui-memory-count-stuck-at-500-actual-traces-exceed-1400/task.md
   • Verification report created: verification-report.md with detailed analysis and testing strategy
