Task 1 Report: Source Metadata Schema And Identity Helpers

Outcome

• Implemented Task 1 in go/vehicle-gateway/internal/stats.
• Added source metadata schema, identity helpers, and focused tests.

RED Evidence

Initial focused test run failed as expected because the new helpers did not exist yet:

cd /Users/lingniu/project/ai-coding/lingniu-vehicle-ingest/go/vehicle-gateway
go test ./internal/stats -run 'TestNormalizeSourceIP|TestNewSourceIdentity|TestUpsertDataSource' -count=1

Result:

• undefined: NormalizeSourceIP
• undefined: NewSourceIdentity
• undefined: SourceIdentity
• undefined: UpsertDataSource

GREEN Evidence

After implementation, the focused tests passed:

cd /Users/lingniu/project/ai-coding/lingniu-vehicle-ingest/go/vehicle-gateway
go test ./internal/stats -run 'TestNormalizeSourceIP|TestNewSourceIdentity|TestUpsertDataSource' -count=1

Result:

• ok lingniu-vehicle-ingest/go/vehicle-gateway/internal/stats 0.927s

Full package verification also passed:

cd /Users/lingniu/project/ai-coding/lingniu-vehicle-ingest/go/vehicle-gateway
go test ./internal/stats -count=1

Result:

• ok lingniu-vehicle-ingest/go/vehicle-gateway/internal/stats 0.355s

Files Changed

• go/vehicle-gateway/internal/stats/schema.go
• go/vehicle-gateway/internal/stats/source.go
• go/vehicle-gateway/internal/stats/source_test.go

Notes

• DataSourceTableSQL was added verbatim to schema.go for the future schema wiring step.
• UpsertDataSource follows the brief exactly, including the nil exec panic, empty-source short circuit, and SQL shape.

Self-Review

• The implementation is tightly scoped to Task 1.
• The new tests cover IP normalization, identity construction, and the SQL shape for the upsert helper.
• No additional concerns at this stage.
