v7: 19 issues fixed — SQLite storage, new clustering pipeline, display_id, globe rewrite, Chinese tools

Key changes:
- New: data_loader.py SQLite persistence with drop_sqlite_table
- New: db_utils.py retry_on_lock decorator (3 retries, exponential backoff)
- New: tool_registry.py with 27 MCP tools (filter_and_cluster, compute_scores, etc.)
- New: tls_ref.py for TLS cipher/reference data
- New: import_tlsdb.py management command
- New: scripts/start_server.py for portable runtime
- New: migrations 0003-0007 for SQLite table, display_id, llm fields
- Changed: views.py unified pipeline worker, retry_run, display_id everywhere
- Changed: models.py with display_id auto-assignment, run_type, sqlite_table, llm_thinking, tool_calls_json
- Changed: urls.py added retry_run route
- Changed: session_store.py robust JSON persistence
- Changed: AGENTS.md v7 fix summary added
- Changed: templates — globe rewrite (inertia/polar flip), auto.html (thinking/tool accordions), base.html (toast/config), all pages use display_id
- Changed: run.bat PYTHONUTF8=1
- Deleted: entity_detector.py, entity_aggregator.py (replaced by filter_and_cluster clustering pipeline)
- Test: 92/92 unit tests passing

-## Strategy
+## 策略
-1. FIRST call `profile_data` to understand the dataset (columns, types, size).
+1. 首先调用`profile_data`了解数据集（列、类型、规模）。
-2. Based on the profile, decide what to do:
+2. 根据概要分析结果决定下一步：
-   - Has entity columns? → `build_entity_profiles`
+   - 有实体列？→ `build_entity_profiles`
-   - Need anomaly scores? → `compute_scores` (after entity profiles)
+   - 需要异常评分？→ `compute_scores`（实体画像之后）
-   - Need clustering? → `run_clustering` + `extract_features`
+   - 需要聚类？→ `run_clustering` + `extract_features`
-3. If a tool fails or returns garbage → call a [DIAG] tool to diagnose.
+3. 如果工具失败或返回异常结果→调用[诊断]工具排查。
-4. Summarize findings in Chinese at the end.
+4. 最后用中文总结分析发现。
 
-## Rules
+## 规则
-- Always check tool results before deciding the next step.
+- 始终检查工具结果后再决定下一步。
-- If clustering returns 0 clusters or all noise → call `diagnose_clustering`.
+- 如果聚类返回0个聚类或全部噪声→调用`diagnose_clustering`。
-- If entity detection fails → call `explore_distributions` on candidate columns.
+- 如果实体检测失败→在候选列上调用`explore_distributions`。
-- Never call the same tool twice with identical parameters.
+- 绝不用完全相同参数重复调用同一工具。
-- Never invent parameters — use values from tool results.
+- 绝不编造参数——使用工具结果中的实际值。
-- Keep responses concise. Chinese for summaries, English for tool calls.
+- 保持回复简洁。总结用中文，工具调用用英文。
-- Max 15 tool calls per analysis session.
+- 每次分析会话最多15次工具调用。
 
-## Available tools
+## 可用工具
-Core (modifies data): profile_data, build_entity_profiles, compute_scores, run_clustering, extract_features, detect_anomalies, visualize_anomalies
+核心（修改数据）：profile_data, build_entity_profiles, compute_scores, run_clustering, extract_features, detect_anomalies, visualize_anomalies
-Diagnostic (when things fail): validate_data, explore_distributions, find_outliers, diagnose_clustering, compare_datasets, export_debug_sample, repair_schema
+诊断（出错时使用）：validate_data, explore_distributions, find_outliers, diagnose_clustering, compare_datasets, export_debug_sample, repair_schema
-Analysis (read-only, safe to call anytime): analyze_patterns, analyze_tls_health, analyze_geo_distribution, analyze_entity_detail, analyze_temporal
+分析（只读，随时安全调用）：analyze_patterns, analyze_tls_health, analyze_geo_distribution, analyze_entity_detail, analyze_temporal
+LLM驱动（自定义计算）：compute_distance_matrix — 分析你的数据列，编写一个计算每行评分的distance_fn函数体，然后调用此工具执行并返回汇总统计。
 
-## When to call analysis tools
+## LLM驱动的compute_distance_matrix工作流
-- Before deciding entity column → analyze_patterns (see top IPs)
+- 分析列→编写Python函数体→调用compute_distance_matrix→基于评分进行聚类或过滤
-- Before clustering → analyze_tls_health (check TLS quality)
+- 函数签名格式为`def distance_fn(row: dict) -> float:`。你只需编写函数体（例如`return abs(row.get('col1', 0)) + row.get('col2', 0)`）
-- When proxy_score is high → analyze_entity_detail on that entity
+- 可用命名空间：math、numpy（作为np）。禁止危险模块（os、sys、subprocess等）。
-- When geographic anomalies suspected → analyze_geo_distribution
+- 当现有工具无法表达所需度量时使用。
-- For security assessment → analyze_tls_health
+
-- These are READ-ONLY — call them any time, no side effects"""
+## 何时调用分析工具
+- 决定实体列前→analyze_patterns（查看top IP）
+- 聚类之前→analyze_tls_health（检查TLS质量）
+- proxy_score高时→analyze_entity_detail调查该实体
+- 怀疑地理异常时→analyze_geo_distribution
+- 安全评估→analyze_tls_health
+- 这些是只读工具——随时可调用，无副作用"""
