"""
Phase 12 — Cloud Resource Foundation: Security-negative integration suite.

Covers T-12-01 through T-12-10 with dedicated negative tests:
  - IDOR: foreign-user/admin cannot browse cloud connections or items
  - Credential disclosure: credentials_enc never returned from browse endpoint
  - SSRF: URL validation invariants preserved for WebDAV/Nextcloud
  - No-byte: browse never calls get_object, MinIO put/delete, or quota mutation
  - Disabled/deleted connection: browse returns 404
  - Provider error sanitization: raw errors not propagated to API consumers
  - Mass assignment: only allowed fields updated on rename

Decision coverage (D-01 through D-18 mapped):
  D-01 provider-agnostic item UUID stable identity — test_same_provider_items_scoped_to_connection
  D-02 connection-ID browse scope — test_foreign_user_cannot_browse_cloud_item
  D-03 admin blocked from cloud browse — test_admin_cannot_browse_cloud_connection
  D-05 same provider multiple connections — test_same_provider_items_scoped_to_connection
  D-06 credentials never in response — test_browse_response_excludes_credentials_and_raw_fields
  D-07 no quota mutation on browse — test_browse_no_quota_mutation
  D-08 no MinIO calls on browse — test_browse_no_minio_calls
  D-14 SSRF protection — test_ssrf_url_validation_invariants
  D-17 disabled connection blocked — test_disabled_connection_browse_blocked
  D-18 no byte download on list_folder — test_no_byte_download_during_browse
