+## Scan worker + AUD0
+
+- API-containern kör en **in-process scan-worker** (poll 2s, atomic claim via
+  `FOR UPDATE SKIP LOCKED`): capture med playwright-core + system-chromium
+  (DNS-only domän måste vara nåbar från server6) → typed `EvidenceRecord`s
+  (runtime-html/dom/computed-style/stylesheet/asset/network-request/screenshot,
+  `confidence: measured`) → `scans.result` (JSONB) → status completed/failed.
+- **AUD0 (fire-and-forget, advisory)**: `c0py.registry_created` (L1),
+  `c0py.scan_created` (L1), `c0py.scan_completed`/`c0py.scan_failed` (L2).
+  tenant_id = Zitadel resourceowner-org (server-side assertat; klienten kan
+  aldrig sätta tenant). AUD0-outage tappar events men blockerar aldrig API:et.
+- `page.evaluate` körs som **ren string** — tsx/esbuild injicerar annars
+  `__name`-helpers som kraschar i browser-kontextet.
