Documented steps
List prior image references with `fly releases -a <app>` (add --image to show the registry image per release).
Identify the image of the release you want to restore (the registry.fly.io/<app>...@sha256:... digest in the releases table).
Redeploy that exact image with `fly deploy -i registry.fly.io/<app>@sha256:<digest> -a <app>`.
Watch the rolling update complete and verify with `fly status` / `fly releases` / `fly logs`.
There is intentionally no `fly rollback` command — the documented mechanism is redeploying a previous image.

Known gotchas
Deploying an older image reverts the CODE but NOT Fly-specific state such as secrets or app config changes made after that release — those are applied from current fly.toml/secrets.
Image retention is not guaranteed indefinitely; if the target image was garbage-collected the digest may be unpullable.
This is not a transactional rollback — confirm the new deployment actually becomes the current release before relying on it.
For rollback of config/secrets too, version-control fly.toml and re-apply the older config rather than only the image.
