Findings-only probe: Lambda Web Adapter container (denoland/deno image) behind Function URL/API GW; GitHub-OIDC role-assume CI auth. Anti-scope: NO event/queue claims — SQS semantics are leaf territory (DPB-29; adversarial F1 lineage).

Acceptance

• gate: probe report with live evidence ids
• gate: go/no-go for the adapter card recorded
