docker manifest inspect defaults to HTTPS and produces a misleading 'no such manifest' for HTTP-only registries like the registry:2 service container. ttl.sh is anonymous, HTTPS-served, and auto-expires images, so the test exercises the same code path real callers will hit.
- Include github.run_attempt in the test tag so workflow reruns don't collide with the previous attempt's image (run_id stays the same across reruns; only run_attempt increments). - Reject initial-interval/max-interval < 1s in wait.sh. A zero value turned the loop into a hot poller against the timeout budget. - Add an outputs: block to the publish job in the README example so needs.publish.outputs.digest actually resolves.

…ondition (#6585) This PR incorporates the [GAR mirror wait action](grafana/shared-workflows#1956) into workflows where there could be a race condition if mirror fails or is slow: 1. `publish-alloy-devel.yml` => this workflow will first publish devel images to GAR, then immediately proceeds to open a PR against `deployment_tools`. We can insert a wait action between the former and latter steps 2. `trigger-argo-workflow-on-tag.yml` => this workflow will trigger an argo deployment workflow that deploys devel images to our internal environment for testing, we can use this wait action as a check to ensure that mirroring is complete before we start opening any PR's against `deployment_tools` as part of the argo workflow --------- Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>

Wait for an image to appear in an OCI registry, or fail after a timeout. Used to bridge the async GAR→DockerHub mirror, consumers can gate downstream work on the DockerHub side catching up.
Polls `docker manifest inspect` with exponential backoff until success or timeout.
