Native Observability 1.0.6 - Added OpenTelemetry and Prometheus observability improvements, including a live Prometheus metrics reader, improved Prometheus metrics building, exporter registry refinements, and route exclusion support for tracing. - Added security and runtime hardening around trace collection, route filtering, and observability settings. - Added Grafana/Prometheus documentation cleanup and aligned OpenTelemetry admin links and README references. - Added Native Observability ECA Bridge integration, including ECA event definitions, event plugin/deriver support, unit coverage, and bridge documentation. - Added Native Observability ECA Bridge Demo module with sample ECA configurations for 500 errors, AJAX requests, slow requests, trace deletion, and trace logging workflows. - Improved the dashboard with span breakdown support, trace metric reading, optional section handling, primary KPI rendering updates, KPI card styling, and dashboard bundle updates. - Added route exclusion unit coverage for core tracing and OpenTelemetry tracing subscribers. - Added OpenTelemetry requirements and Prometheus metrics unit coverage. - Updated PHPUnit tests to avoid deprecated docblock coverage metadata where applicable. - Fixed PHPCS and PHPUnit regressions introduced during the new observability integrations. - Split frontend linting responsibilities between generic Drupal linting and dashboard-specific asset validation. - Added explicit Prettier, ESLint, Stylelint, and dashboard asset validation configuration to keep JS, SCSS, and compiled CSS/JS checks separate. - Integrated additional GitLab CI validation jobs as non-blocking checks while keeping PHPCS blocking. - Fixed remaining ESLint/Prettier formatting issues in execution AJAX correlation and report preview JavaScript. This release focuses on observability depth, ECA interoperability, Prometheus/Grafana readiness, dashboard metrics improvements, and CI/lint hardening.
