Summary: Found compile-blocking issue in otel FieldConf map and a missing middleware function reference in router.

• [🚫Must Fix] backend/modules/observability/lib/otel/otel_convert.go: Struct literal for FieldConf uses non-existent field names (attributeKey, isTag, dataType). Replace with AttributeKey, IsTag, DataType.
• [🚨Should Fix] backend/api/router/coze/loop/apis/coze.loop.apis.go: Route references _gettrajectoryconfigMw but the stub is not defined in middleware.go. Add the missing middleware function.

Please address these to unblock compilation and ensure routing consistency.

[💡Suggestion] Sorting children can use sort.Slice for clarity and O(n log n) complexity: sort.Slice(children, func(i, j int) bool { return children[i].StartTime < children[j].StartTime }).

[🚫Must Fix] Struct literal uses unknown field names for FieldConf

attributeKey, isTag, and dataType are not fields of FieldConf (the correct names are AttributeKey, IsTag, and DataType). This will fail to compile with “unknown field” errors. Please use the exported field names.

Suggestion:

"psm": {
    AttributeKey: []string{"service.name"},
    IsTag:        false,
    DataType:     dataTypeString,
},
