The change removes proper value escaping from build_escaped_term_filter and uses direct f-string interpolation: f"gen_ai.conversation.id:{conversation_id}". If conversation_id (user-provided via URL path) contains spaces, the query parses as gen_ai.conversation.id:first_word second_word where second_word becomes unrelated free-text search, returning incorrect results silently. Parentheses cause parsing errors. While handle_query_errors() catches InvalidSearchQuery, silent wrong results are not caught. The old code quoted and escaped values to prevent this.

The removed call to _validate_time_window for Dataset.EventsAnalyticsPlatform was the only validation enforcing the 5-minute minimum time window when SnubaQueryValidator is used directly (via MetricIssueDetectorValidator). While AlertRuleSerializer has its own duplicate validation at lines 214-219, MetricIssueDetectorValidator at metric_issue_detector.py:194 uses SnubaQueryValidator(timeWindowSeconds=True) as a child serializer without any time window validation. This allows creating EAP metric issue detectors with invalid sub-5-minute time windows, which will cause subscription errors at runtime.

This workflow uses pull_request_target trigger with secrets: inherit, which passes all repository secrets to the reusable workflow getsentry/craft/.github/workflows/changelog-preview.yml. If that external workflow checks out fork code (PR head ref) and executes it, an attacker could exfiltrate secrets by opening a malicious PR. The workflow also grants elevated permissions (contents: write, pull-requests: write, statuses: write) which amplifies potential impact.
