📝 Walkthrough

The changes add automatic outbound-link tracking, outbound event ingestion and analytics, Plausible import support, and outbound usage reporting across the tracker, backend, and web app.

Changes: Outbound Link Tracking and Analytics

Layer / File(s)	Summary
Outbound event contract and ingestion backend/apps/cloud/src/analytics/..., backend/apps/community/src/analytics/..., backend/migrations/clickhouse/*	Both backend applications accept outbound events with validated URLs and optional titles, transform them into outbound records, and store the URL in ClickHouse. Ingestion tests cover event context, bot filtering, and custom-event handling.
Browser capture and setup packages/tracker-js/src/*, packages/tracker-js/tests/outbound.test.ts, packages/tracker-js/README.md, web/app/ui/TrackingSetup.tsx, docs/content/docs/script-reference.mdx, web/public/locales/en.json	The tracker can capture qualifying link clicks when outbound tracking is enabled, filter and normalize destinations, and stop automatic capture. Setup snippets and documentation describe the option.
Outbound breakdown queries and display backend/apps/cloud/src/analytics/v2/*, backend/apps/community/src/analytics/v2/*, web/app/pages/Project/View/v2/BreakdownPanel.tsx, web/app/pages/Project/tabs/Traffic/TrafficView.tsx, web/app/lib/models/Entry.ts, web/app/pages/Project/View/ViewProject.helpers.tsx, docs/content/docs/api/stats-v2.mdx	The analytics APIs provide an outbound-link breakdown with click and visitor metrics. The traffic interface displays destination links, supports CSV export, and handles outbound-specific loading and empty states.
Plausible import mapping backend/apps/cloud/src/data-import/*, backend/apps/community/src/data-import/*, backend/tests/data-import-mappers.spec.ts, docs/content/docs/data-import.mdx, web/app/routes/projects.settings.$id.tsx	Plausible outbound-link rows become outbound records with available destination URLs. Imported outbound records are included in cleanup, and import tests and documentation cover the mapping.
Usage accounting and data lifecycle backend/apps/cloud/src/admin/admin.service.ts, backend/apps/cloud/src/project/*, backend/apps/cloud/src/task-manager/task-manager.service.ts, backend/apps/cloud/src/user/*, backend/apps/community/src/project/project.service.ts, web/app/pages/UserSettings/UserSettings.tsx, web/app/pages/Project/Settings/components/DeleteDataModal.tsx, web/app/lib/models/Usageinfo.ts, web/public/locales/en.json	Usage and activity queries include outbound events. Project deletion and data-deletion types include outbound events, and billing displays show outbound-link usage.

Merge Risk: 🔵 Low · up to 91a86

Some breakdowns can show misleading click counts, imported clicks can inflate a monthly usage count, and clicks from pages with long query strings can be lost. These should be corrected, but their bounded impact does not establish a broad release blocker.

Inline comments:
Review comments at @backend/apps/cloud/src/admin/admin.service.ts:
- Line 2141: Update the admin monthly usage query containing the event type
filter to add an importID IS NULL condition, excluding imported outbound rows
while preserving counting of non-imported billable events.

Review comments at @backend/apps/cloud/src/analytics/v2/analytics-v2.service.ts:
- Around line 283-296: Update the metric validation around isOutbound in both
analytics v2 service implementations to reject any clicks metric when the
dimension is not outbound_link, using the existing UnprocessableEntityException
pattern and preserving the current outbound validation.

Review comments at @packages/tracker-js/src/Lib.ts:
- Around line 451-455: Update the outbound tracking payload in the method
containing sendRequest and getEventContext so the qs value is truncated to 2048
characters before submission, while preserving undefined when no query string
exists. Leave campaign fields and the existing error handling unchanged.
