        MC_API_KEY: ${{ secrets.MC_API_KEY }}
        GCLOUD_PROJECT: ${{ vars.GCLOUD_PROJECT }}
        REPORTING_PUBLIC_API_TARGET: v2alpha.reporting.dev.halo-cmm.org:8443

I went ahead and added the variable for all 3 environments

Suggestion:

${{ vars.REPORTING_PUBLIC_API_TARGET }}

 * Test for correctness of an existing CMMS on Kubernetes where the EDP simulators use
 * [SyntheticGeneratorEventQuery] with [SyntheticGenerationSpecs.SYNTHETIC_POPULATION_SPEC_LARGE].
 * The computation composition is using ACDP by assumption.

nit: document that this assuming that there's a Reporting system connected to the CMMS

          listEventGroupsRequest {
            parent = measurementConsumerName
            pageSize = 1000

nit: technically you still should be looping through to exhaust all pages regardless of what page size you set rather than relying on the fact that our current impl will give you the results

    try {
      return reportingSetsClient
        .withAuthenticationKey(apiAuthenticationKey)

The API key is only for the Kingdom public API.

Code quote:

.withAuthenticationKey(apiAuthenticationKey)

        Report.State.UNRECOGNIZED,
        Report.State.STATE_UNSPECIFIED -> delay(5000)
      }

Add some delay here so we're not polling as fast as possible.

    override val reportingTestHarness: ReportingUserSimulator?
      get() = null

So this will only work when run on cloud? I assume we're hitting some GHA limit if we try to do this in a local cluster?

Code quote:

null
