From 2702e07e7d4b348c11159d34da15c4b66cd2b74a Mon Sep 17 00:00:00 2001 From: Operations Center Bot Date: Thu, 25 Jun 2026 15:33:04 -0400 Subject: [PATCH 1/4] feat(observer): add extraction fidelity metric (message_quality_rate) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a second quality axis to the extraction-health system alongside the existing presence-only success_rate. message_quality_rate measures the fraction of assertion messages that are informative (non-empty, ≥10 chars, not a bare exception-type placeholder like "TimeoutError"). Changes: - query_flaky.py: ExtractionHealth gains message_quality_rate + low_quality_messages; get_extraction_health() classifies messages as empty/too_short/bare_exception_type - cli.py: table format surfaces message_quality_rate and low_quality_messages sections; fires MESSAGE_QUALITY_RATE_LOW alert when quality is low - extraction_health_history.py + extraction_history_collector.py: persist message_quality_rate in ExtractionHealthSnapshot JSONL (backwards-compatible) - flaky_test_alert_config.py + flaky_test_alerts.py: alert channel and threshold for MESSAGE_QUALITY_RATE_LOW (WARNING <80%, CRITICAL <50%, EMERGENCY <10%) - docs/reference/EXTRACTION_FIDELITY_METRIC.md: full reference doc covering quality gates, alert thresholds, CLI examples, and JSONL storage schema Tests: 239 fidelity-metric tests across 5 test files; 1667 observer unit tests pass.
