fix(chdb): return error on log_scores row scan failure

Previously a per-row scan error was logged and skipped with continue, so a
decode failure (e.g. the UInt64->int64 regression) produced a 200 response
with partial or empty data and no signal to the client. Fail the request
instead so the HTTP handlers return 500. Also check rows.Err() after iteration.

+- Empty results: `s-maxage=260,max-age=360`
+
+#### Comparison with Legacy API
+The v2 API offers significant improvements over `/api/server/scores/{server}/{mode}`:
+
+| Feature | Legacy API | v2 API |
+|---------|------------|--------|
+| **Record limit** | 10,000 | 50,000 |
+| **Time format** | Unix timestamps only | Unix timestamps + relative time |
+| **Response format** | Legacy JSON/CSV | Grafana table format |
+| **Time range** | Limited by `since` parameter | Full `from`/`to` range support |
+| **Maximum range** | No explicit limit | 90 days |
+| **Performance** | MySQL + ClickHouse | ClickHouse optimized |
+
+#### Migration Guide
+To migrate from legacy API to v2:
+
+**Legacy:**
+```
+/api/server/scores/192.0.2.1/json?limit=10000&since=1753500000&monitor=*
+```
+
+**V2 equivalent:**
+```
+/api/v2/server/scores/192.0.2.1/json?from=1753500000&to=0s&monitor=*&maxDataPoints=10000
+```
+
+**V2 with relative time:**
+```
+/api/v2/server/scores/192.0.2.1/json?from=-3d&to=-1h&monitor=*
+```

+
+## Health Check Endpoints
+
+### Health Check
+**GET** `:9019/health`
+
+Returns server health status by testing database connections.
+
+#### Query Parameters
+- `reset`: Boolean to reset database connection pool
+
+#### Response
+- `200 OK`: "ok" - All systems healthy
+- `503 Service Unavailable`: "db ping err" - Database connectivity issues
+
+### Metrics
+**GET** `:9020/metrics`
+
+Prometheus metrics endpoint for monitoring and observability.
+
+---
+
+## Error Handling
+
+### Standard HTTP Status Codes
+- `200 OK`: Successful request
+- `308 Permanent Redirect`: URL canonicalization
+- `400 Bad Request`: Invalid request parameters
+- `404 Not Found`: Resource not found
+- `500 Internal Server Error`: Server-side error
+- `503 Service Unavailable`: Service temporarily unavailable
+
+### Error Response Format
+Most endpoints return plain text error messages for non-2xx responses. Some endpoints may return JSON error objects.
+
+---
+
+## Data Sources
+
+The API integrates multiple data sources:
+- **MySQL**: Operational data (servers, zones, accounts, current scores)
+- **ClickHouse**: Analytics data (DNS query logs, historical scoring data)
+
+Different endpoints may use different data sources, and some endpoints allow source selection via query parameters.
+
+---
+
+## Rate Limiting and Caching
+
+The API implements extensive caching at multiple levels:
+- **Response-level caching**: Each endpoint sets appropriate `Cache-Control` headers
+- **Database query optimization**: Efficient queries with proper indexing
+- **CDN integration**: Headers configured for CDN caching
+
+Cache durations vary by endpoint and data freshness, ranging from 30 seconds for real-time data to 8 hours for historical data.

+# DETAILED IMPLEMENTATION PLAN: Grafana Time Range API with Future Downsampling Support
+
+## Overview
+Implement a new Grafana-compatible API endpoint `/api/v2/server/scores/{server}/{mode}` that returns time series data in Grafana format with time range support and future downsampling capabilities.
+
+## API Specification
+
+### Endpoint
+- **URL**: `/api/v2/server/scores/{server}/{mode}`
+- **Method**: GET
+- **Path Parameters**:
+  - `server`: Server IP address or ID (same validation as existing API)
+  - `mode`: Only `json` supported initially
+
+### Query Parameters (following Grafana conventions)
+- `from`: Unix timestamp in seconds (required)
+- `to`: Unix timestamp in seconds (required) 
+- `maxDataPoints`: Integer, default 50000, max 50000 (for future downsampling)
+- `monitor`: Monitor ID, name prefix, or "*" for all (optional, same as existing)
+- `interval`: Future downsampling interval like "1m", "5m", "1h" (optional, not implemented initially)
+
+### Response Format
+Grafana table format JSON array (more efficient than separate series):
+```json
+[
+  {
+    "target": "monitor{name=zakim1-yfhw4a}",
+    "tags": {
+      "monitor_id": "126",
+      "monitor_name": "zakim1-yfhw4a",
+      "type": "monitor",
+      "status": "active"
+    },
+    "columns": [
+      {"text": "time", "type": "time"},
+      {"text": "score", "type": "number"},
+      {"text": "rtt", "type": "number", "unit": "ms"},
+      {"text": "offset", "type": "number", "unit": "s"}
+    ],
+    "values": [
+      [1753431667000, 20.0, 18.865, -0.000267],
+      [1753431419000, 20.0, 18.96, -0.000390],
+      [1753431151000, 20.0, 18.073, -0.000768],
+      [1753430063000, 20.0, 18.209, null]
+    ]
+  }
+]
+```
+
+## Implementation Details
+
+### 1. Server Routing (`server/server.go`)
+Add new route after existing scores routes:
+```go
+e.GET("/api/v2/server/scores/:server/:mode", srv.scoresTimeRange)
+```
+
+**Note**: Initially attempted `:server.:mode` pattern, but Echo router cannot properly parse IP addresses with dots using this pattern. Changed to `:server/:mode` to match existing API pattern and ensure compatibility with IP addresses like `23.155.40.38`.
+
+## Key Implementation Clarifications
+
+### Monitor Filtering Behavior
+- **monitor=\***: Return ALL monitors (no monitor count limit)
+- **50k datapoint limit**: Applied in database query (LIMIT clause)
+- Return whatever data we get from database to user (no post-processing truncation)
+
+### Null Value Handling Strategy
+- **Score**: Always include (should never be null)
+- **RTT**: Skip datapoints where RTT is null
+- **Offset**: Skip datapoints where offset is null
+
+### Time Range Validation Rules
+- **Zero duration**: Return 400 Bad Request
+- **Future timestamps**: Allow for now
+- **Minimum range**: 1 second
+- **Maximum range**: 90 days
+
+### 2. New Handler Function (`server/grafana.go`)
+
+#### Function Signature
+```go
+func (srv *Server) scoresTimeRange(c echo.Context) error
+```
+
+#### Parameter Parsing & Validation
+```go
+// Extend existing historyParameters struct for time range support
+type timeRangeParams struct {
+    historyParameters // embed existing struct
+    from              time.Time  
+    to                time.Time
+    maxDataPoints     int
+    interval          string // for future downsampling
+}
+
+func (srv *Server) parseTimeRangeParams(ctx context.Context, c echo.Context) (timeRangeParams, error) {
+    // Start with existing parameter parsing logic
+    baseParams, err := srv.getHistoryParameters(ctx, c)
+    if err != nil {
+        return timeRangeParams{}, err
+    }
+    
+    // Parse and validate from/to second timestamps
+    // Validate time range (max 90 days, min 1 second)
+    // Parse maxDataPoints (default 50000, max 50000)
+    // Return extended parameters
+}
+```
+
+#### Response Structure
+```go
+type ColumnDef struct {
+    Text string `json:"text"`
+    Type string `json:"type"`
+    Unit string `json:"unit,omitempty"`
+}
+
+type GrafanaTableSeries struct {
+    Target  string            `json:"target"`
+    Tags    map[string]string `json:"tags"`
+    Columns []ColumnDef       `json:"columns"`
+    Values  [][]interface{}   `json:"values"`
+}
+
+type GrafanaTimeSeriesResponse []GrafanaTableSeries
+```
+
+#### Cache Control
+```go
+// Reuse existing setHistoryCacheControl function for consistency
+// Logic based on data recency and entry count:
+// - Empty or >8h old data: "s-maxage=260,max-age=360"
+// - Single entry: "s-maxage=60,max-age=35" 
+// - Multiple entries: "s-maxage=90,max-age=120"
+setHistoryCacheControl(c, history)
+```
+
+### 3. ClickHouse Data Access (`chdb/logscores.go`)
+
+#### New Method
+```go
+func (d *ClickHouse) LogscoresTimeRange(ctx context.Context, serverID, monitorID int, from, to time.Time, limit int) ([]ntpdb.LogScore, error) {
+    // Build query with time range WHERE clause
+    // Always order by ts ASC (Grafana convention)
+    // Apply limit to prevent memory issues
+    // Use same row scanning logic as existing Logscores method
+}
+```
+
+#### Query Structure
+```sql
+SELECT id, monitor_id, server_id, ts,
+       toFloat64(score), toFloat64(step), offset,
+       rtt, leap, warning, error
+FROM log_scores  
+WHERE server_id = ?
+  AND ts >= ?
+  AND ts <= ?
+  [AND monitor_id = ?]  -- if specific monitor requested
+ORDER BY ts ASC
+LIMIT ?
+```
+
+### 4. Data Transformation Logic (`server/grafana.go`)
+
+#### Core Transformation Function
+```go
+func transformToGrafanaTableFormat(history *logscores.LogScoreHistory, monitors []ntpdb.Monitor) GrafanaTimeSeriesResponse {
+    // Group data by monitor_id (one series per monitor)
+    // Create table format with columns: time, score, rtt, offset
+    // Convert timestamps to milliseconds
+    // Build proper target names and tags
+    // Handle null values appropriately in table values
+}
+```
+
+#### Grouping Strategy
+1. **Group by Monitor**: One table series per monitor
+2. **Table Columns**: time, score, rtt, offset (all metrics in one table)
+3. **Target Naming**: `monitor{name={sanitized_monitor_name}}`
+4. **Tag Structure**: Include monitor metadata (no metric type needed)
+5. **Monitor Status**: Query real monitor data using `q.GetServerScores()` like existing API
+6. **Series Ordering**: No guaranteed order (standard Grafana behavior)
+7. **Efficiency**: More efficient than separate series - less JSON overhead
+
+#### Timestamp Conversion
+```go
+timestampMs := logScore.Ts.Unix() * 1000
+```
+
+### 5. Error Handling
+
+#### Validation Errors (400 Bad Request)
+- Invalid timestamp format
+- from >= to (including zero duration)
+- Time range too large (> 90 days)
+- Time range too small (< 1 second minimum)
+- maxDataPoints > 50000
+- Invalid mode (not "json")
+
+#### Not Found Errors (404)
+- Server not found
+- Monitor not found  
+- Server deleted
+
+#### Server Errors (500)
+- ClickHouse connection issues
+- Database query errors
+
+### 6. Future Downsampling Design
+
+#### API Extension Points
+- `interval` parameter parsing ready
+- `maxDataPoints` limit already enforced
+- Response format supports downsampled data seamlessly
+
+#### Downsampling Algorithm (Future Implementation)
+```go
+// When datapoints > maxDataPoints:
+// 1. Calculate downsample interval: (to - from) / maxDataPoints
+// 2. Group data into time buckets  
+// 3. Aggregate per bucket: avg for score/rtt, last for offset
+// 4. Return aggregated datapoints
+```
+
+## Testing Strategy
+
+### Unit Tests
+- Parameter parsing and validation
+- Data transformation logic
+- Error handling scenarios
+- Timestamp conversion accuracy
+
+### Integration Tests  
+- End-to-end API requests
+- ClickHouse query execution
+- Multiple monitor scenarios
+- Large time range handling
+
+### Manual Testing
+- Grafana integration testing
+- Performance with various time ranges
+- Cache behavior validation
+
+## Performance Considerations
+
+### Current Implementation
+- 50k datapoint limit applied in database query (LIMIT clause) (covers ~few weeks of data)
+- ClickHouse-only for better range query performance
+- Proper indexing on (server_id, ts) assumed
+- Table format more efficient than separate time series (less JSON overhead)
+
+### Future Optimizations (Critical for Production)
+- **Downsampling for large ranges**: Essential for 90-day queries with reasonable performance
+- Query optimization based on range size
+- Potential parallel monitor queries
+- Adaptive sampling rates based on time range duration
+
+## Documentation Updates
+
+### API.md Addition
+```markdown
+### 7. Server Scores Time Range (v2)
+
+**GET** `/api/v2/server/scores/{server}/{mode}`
+
+Grafana-compatible time series endpoint for NTP server scoring data.
+
+#### Path Parameters
+- `server`: Server IP address or ID
+- `mode`: Response format (`json` only)
+
+#### Query Parameters  
+- `from`: Start time as Unix timestamp in seconds (required)
+- `to`: End time as Unix timestamp in seconds (required)
+- `maxDataPoints`: Maximum data points to return (default: 50000, max: 50000)
+- `monitor`: Monitor filter (ID, name prefix, or "*" for all)
+
+#### Response Format
+Grafana table format array with one series per monitor containing all metrics as columns.
+```
+
+## Key Research Findings
+
+### Grafana Error Format Requirements
+- **HTTP Status Codes**: Standard 400/404/500 work fine
+- **Response Body**: JSON preferred with `Content-Type: application/json`
+- **Structure**: Simple `{"error": "message", "status": code}` is sufficient
+- **Compatibility**: Existing Echo error patterns are Grafana-compatible
+
+### Data Volume Considerations
+- **50k Datapoint Limit**: Only covers ~few weeks of data, not sufficient for 90-day ranges
+- **Downsampling Critical**: Required for production use with 90-day time ranges
+- **Current Approach**: Acceptable for MVP, downsampling essential for full utility
+
+## Implementation Checklist
+
+### Phase 0: Grafana Table Format Validation ✅ **COMPLETED**
+- [x] Add test endpoint `/api/v2/test/grafana-table` returning sample table format
+- [x] Implement Grafana table format response structures in `server/grafana.go`
+- [x] Add structured logging and OpenTelemetry tracing to test endpoint
+- [x] Verify endpoint compiles and serves correct JSON format
+- [x] Test endpoint response format and headers (CORS, Content-Type, Cache-Control)
+- [ ] Test with actual Grafana instance to validate table format compatibility
+- [ ] Confirm time series panels render table format correctly
+- [ ] Validate column types and units display properly
+
+#### Phase 0 Implementation Details
+**Files Created/Modified:**
+- `server/grafana.go`: New file containing Grafana table format structures and test endpoint
+- `server/server.go`: Added route `e.GET("/api/v2/test/grafana-table", srv.testGrafanaTable)`
+
+**Test Endpoint Features:**
+- **URL**: `http://localhost:8030/api/v2/test/grafana-table`
+- **Response Format**: Grafana table format with realistic NTP Pool data
+- **Sample Data**: Two monitor series (zakim1-yfhw4a, nj2-mon01) with time-based values
+- **Columns**: time, score, rtt (ms), offset (s) with proper units
+- **Null Handling**: Demonstrates null offset values
+- **Headers**: CORS, JSON content-type, cache control
+- **Observability**: Structured logging with context, OpenTelemetry tracing
+
+**Recommended Grafana Data Source**: JSON API plugin (`marcusolsson-json-datasource`) - ideal for REST APIs returning table format JSON
+
+### Phase 1: Core Implementation ✅ **COMPLETED**
+- [x] Add route in server.go (fixed routing pattern from `:server.:mode` to `:server/:mode`)
+- [x] Implement parseTimeRangeParams function for parameter validation
+- [x] Add LogscoresTimeRange method to ClickHouse with time range filtering
+- [x] Implement transformToGrafanaTableFormat function with monitor grouping
+- [x] Add scoresTimeRange handler with full error handling
+- [x] Error handling and validation (reuse existing Echo patterns)
+- [x] Cache control headers (reuse setHistoryCacheControl)
+
+#### Phase 1 Implementation Details
+**Key Components Built:**
+- **Route Pattern**: `/api/v2/server/scores/:server/:mode` (matches existing API consistency)
+- **Parameter Validation**: Full validation of `from`/`to` timestamps, `maxDataPoints`, time ranges
+- **ClickHouse Integration**: `LogscoresTimeRange()` with time-based WHERE clauses and ASC ordering
+- **Data Transformation**: Grafana table format with monitor grouping and null value handling
+- **Complete Handler**: `scoresTimeRange()` with server validation, error handling, caching, and CORS
+
+**Routing Fix**: Changed from `:server.:mode` to `:server/:mode` to resolve Echo router issue with IP addresses containing dots (e.g., `23.155.40.38`).
+
+**Files Created/Modified in Phase 1:**
+- `server/grafana.go`: Complete implementation with all structures and functions
+  - `timeRangeParams` struct and `parseTimeRangeParams()` function
+  - `transformToGrafanaTableFormat()` function with monitor grouping
+  - `scoresTimeRange()` handler with full error handling
+  - `sanitizeMonitorName()` utility function
+- `server/server.go`: Added route `e.GET("/api/v2/server/scores/:server/:mode", srv.scoresTimeRange)`
+- `chdb/logscores.go`: Added `LogscoresTimeRange()` method for time-based queries
+
+**Production Testing Results** (July 25, 2025):
+- ✅ **Real Data Verification**: Successfully tested with server `102.64.112.164` over 12-hour time range
+- ✅ **Multiple Monitor Support**: Returns data for multiple monitors (`defra1-210hw9t`, `recentmedian`)
+- ✅ **Data Quality Validation**: 
+  - RTT conversion (microseconds → milliseconds): ✅ Working
+  - Timestamp conversion (seconds → milliseconds): ✅ Working  
+  - Null value handling: ✅ Working (recentmedian has null RTT/offset as expected)
+  - Monitor grouping: ✅ Working (one series per monitor)
+- ✅ **API Parameter Changes**: Successfully changed from milliseconds to seconds for user-friendliness
+- ✅ **Volume Testing**: Handles 100+ data points per monitor efficiently
+- ✅ **Error Handling**: All validation working (400 for invalid params, 404 for missing servers)
+- ✅ **Performance**: Sub-second response times for 12-hour ranges
+
+**Sample Working Request:**
+```bash
+curl 'http://localhost:8030/api/v2/server/scores/102.64.112.164/json?from=1753457764&to=1753500964&monitor=*'
+```
+
+### Phase 2: Testing & Polish
+- [ ] Unit tests for all functions
+- [ ] Integration tests
+- [ ] Manual Grafana testing with real data
+- [ ] Performance testing with large ranges (up to 50k points)
+- [ ] API documentation updates
+
+### Phase 3: Future Enhancement Ready
+- [ ] Interval parameter parsing (no-op initially)
+- [ ] Downsampling framework hooks (critical for 90-day ranges)
+- [ ] Monitoring and metrics for new endpoint
+
+This design provides a solid foundation for immediate Grafana integration while being fully prepared for future downsampling capabilities without breaking changes.
+
+## Critical Notes for Production
+
+- **Downsampling Required**: 50k datapoint limit means 90-day ranges will hit limits quickly
+- **Table Format Validation**: Phase 0 testing ensures Grafana compatibility before full implementation
+- **Error Handling**: Existing Echo patterns are sufficient for Grafana requirements
+- **Scalability**: Current design handles weeks of data well, downsampling needed for months
