See [Changes files](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/guides/committing-changes.md#changes-files) for more information. - [x] Input data is properly validated, `SELECT *` is avoided, SQL injection is prevented (using placeholders for values in statements), JS inline code is prevented especially for url redirects, and untrusted data interpolated into shell scripts/commands is validated against shell metacharacters. ## Testing - [x] Added/updated automated tests - [x] QA'd all new/changed functionality manually ## Database migrations - [x] Ensured the correct collation is explicitly set for character columns (`COLLATE utf8mb4_unicode_ci`). ## New Fleet configuration settings - [x] Setting(s) is/are explicitly excluded from GitOps <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Route-aware OpenTelemetry trace sampling with tiered default ratios (very low for select high-volume routes, reduced rate for admin reads, full sampling otherwise). * Admin-only GET/PATCH /debug/trace_sampler to view and update sampling ratios and a runtime "force full" toggle. * Liveness probe endpoints (/healthz, /version, /metrics) are excluded from tracing; settings propagate to replicas at runtime without restart. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
