#requires -Version 7.0
<#
.SYNOPSIS
  One-time bootstrap of stable hosted agents for the Foundry.Hosting.IntegrationTests suite.

.DESCRIPTION
  The IT fixture targets stable, scenario-keyed agent names (e.g. it-happy-path) and only
  manages versions on each test run. The agent itself must already exist AND its managed
  identity must hold the Foundry User role on the project scope, otherwise inbound
  inference calls fail with HTTP 500 PermissionDenied.

  This script idempotently creates each scenario agent (with a placeholder version) and
  grants Foundry User on the project to its managed identity. Re-run it safely; existing
  agents and role assignments are left in place.

.PARAMETER ProjectEndpoint
  Foundry project endpoint, e.g. https://<account>.services.ai.azure.com/api/projects/<project>

.PARAMETER Image
  Container image reference for the placeholder version (e.g. <acr>.azurecr.io/foundry-hosting-it:<tag>).
  Use the value emitted by scripts/it-build-image.ps1.

.NOTES
  Per-scenario data-plane RBAC (e.g. `Search Index Data Reader` on the Azure AI Search service
  for the `azure-search-rag` scenario) is intentionally NOT performed by this script. Search,
  Cosmos, and other backing services are treated as pre-existing infrastructure. Grant the
  scenario-specific data role to the agent's managed identity manually after the first run
  (see dotnet/tests/Foundry.Hosting.IntegrationTests/README.md).
