[P1.5-S6-ARI-44] UC3 connector smoke test

[bjridicodes]

Ticket: P1.5-S6-06

Type: Validation | Est: 1d

Goal: GCPLogConnector returns real log lines from all 4 UC3 native GCP service types on the live UC3 GCP project.

Pre-conditions: P1.5-S6-01 (TF applied), P1.5-S6-02 (connector refactored), P1.5-S6-03 (resource types in conf.yaml)

Scope:

• Generate test activity on each UC3 service:
  • BigQuery: submit a job referencing a non-existent table
  • Cloud Functions: deploy a minimal function and trigger a timeout (or use existing CF if present)
  • Pub/Sub: push messages faster than the subscriber consumes to build a backlog
  • GCS: attempt to read a file with insufficient permissions
• For each service type: run GCPLogConnector.query_logs() with the correct resource type template; assert ≥ 1 log line returned
• Document results in a brief smoke test report (tests/acceptance/uc3_smoke_test.md)

Acceptance criteria:

• BigQuery: ≥ 1 log line returned from bigquery_dataset resource type
• Cloud Functions: ≥ 1 log line returned from cloud_function resource type
• Pub/Sub: ≥ 1 log line OR ≥ 1 metric signal returned
• GCS: ≥ 1 log line returned from gcs_bucket resource type
• Smoke test report committed
