+/**
+ * STAGED DEEP-PATH E2E VALIDATION LANE
+ * ====================================
+ * Full customer journey, end to end, against a STAGING environment:
+ *
+ *   1. Operator intake review        (public submit → review-queue inspection)
+ *   2. Tenant provisioning           (activation/provision)
+ *   3. Invite issuance               (auto-issued on valid submit; captured)
+ *   4. User activation               (/activate?token → /welcome)
+ *   5. Onboarding completion         (/api/onboarding/complete → COMPLETED)
+ *   6. First APPROVED governed action  (gateway invoke → executed → live decision + receipt)
+ *   7. First DENIED/fail-closed action (gateway invoke → denied/blocked, NO execution)
+ *   8. Receipt / proof-chain validation (verifyReceipt server-side)
+ *
+ * DESIGN PRINCIPLES (non-negotiable — these encode the launch boundaries):
+ *   - A SKIP IS NOT A PASS. When a prerequisite is absent, the scenario is
+ *     SKIPPED with an explicit "prerequisite not provided" reason. It is never
+ *     silently treated as green.
+ *   - LIVE-OR-BLOCKER for governed actions. If MCP_GATEWAY_BASE_URL is provided
+ *     but the gateway is not healthy, or the control plane reports the decision
+ *     source as anything other than 'live', the governed scenarios FAIL (a
+ *     blocker), they do not skip. Mock/empty/fixture sources are rejected.
+ *   - NO FABRICATED PROOF. The governed-action checks call the REAL gateway
+ *     (`POST /mcp/tools/invoke`) and read the REAL control-plane decision and
+ *     receipt. There is no in-test mock for scenarios 6–8.
+ *   - DENIED MUST NOT EXECUTE. Scenario 7 asserts lifecycle_status is
+ *     denied|blocked AND that no execution side-effect was produced.
+ *   - NO LOCALHOST. Every page/request is captured; a single localhost call
+ *     fails the run. The network log is written to the evidence directory.
+ *
+ * KNOWN CAVEAT (carried into evidence, not hidden):
+ *   Control's receipt route has an open TODO: prev_hash is not fetched, so
+ *   `chainValid` cannot be established control-side for a single receipt
+ *   (verifyReceipt emits "Previous receipt was not provided"). This lane
+ *   asserts `signatureValid` (the strong, available proof) and RECORDS the
+ *   chainValid status + caveat honestly. Full multi-link chain validation is a
+ *   gateway-side concern until that TODO lands.
+ *
+ * RUN:
+ *   pnpm exec playwright test tests/smoke/deep-path-e2e.spec.ts \
+ *     --config=playwright.config.ts
+ *
+ * REQUIRED ENV (see output/DEEP_PATH_E2E_PREREQS.md for the operator runbook):
+ *   PUBLIC_SITE_URL            staging public web base (keon.systems equivalent)
+ *   KEON_CONTROL_BASE_URL      staging control base (control.keon.systems equivalent)
+ *   MCP_GATEWAY_BASE_URL       staging Runtime/MCP Gateway base (for invoke + health)
+ *   E2E_TEST_EMAIL             approved, non-billable test email
+ *   E2E_TENANT_ID              non-billable test tenant id
+ *   E2E_OPERATOR_SESSION       operator session cookie value (review queue + reads)
+ *   E2E_USER_SESSION           activated-user session cookie value (governed reads)
+ *   E2E_GATEWAY_AUTH           gateway auth header value (e.g. "Bearer <key>")
+ *   E2E_APPROVED_TOOL          tool name the active policy ALLOWS
+ *   E2E_APPROVED_INPUT_JSON    JSON input for the approved tool
+ *   E2E_DENIED_TOOL            tool name the active policy DENIES (fail-closed)
+ *   E2E_DENIED_INPUT_JSON      JSON input for the denied tool
+ *   E2E_INVITE_TOKEN           (optional) raw invite token if captured out-of-band
+ *
+ * EVIDENCE: written under e2e-evidence/deep-path-<ISO>/ (screenshots, network
+ * log, api captures, manifest.json).
