AMD has no L4 file yet, so `nightly-test` does not select an additional suite.

Multiple PR tier labels combine their suites behind one image build.

-    **Trigger boundary:** AMD label handling has two layers. First, the external `vllm-omni-amd-ci` Buildkite pipeline condition decides whether a GitHub label event creates a build. Only after that build starts does this repository's bootstrap inspect all current PR labels and select L2, L3, or both. Repository-side selection therefore cannot make a `merge-test` event start AMD CI by itself. The external condition must admit both `ready` and `merge-test`, while preserving the legacy `amd-test` trigger and non-PR `main` / scheduled builds. For PR builds without a `DEBUG_TEST_YAML` override, an unreadable label set fails the bootstrap instead of silently selecting the wrong tier. Debug overrides skip label lookup and are validated directly; invalid values, including whitespace-only values, fail the bootstrap. Keep `nightly-test` out of the AMD condition until an AMD L4 suite exists; otherwise it would start a build without providing nightly coverage.

Only after that build starts does this repository's bootstrap inspect all current PR labels and select the ready, merge, nightly, or combined suites. Repository-side selection therefore cannot start AMD CI by itself. AMD-only nightly validation uses both `amd-test` and `nightly-test`: the external condition should accept an event for either label only when the complete PR label set contains both. `amd-test` admits the AMD pipeline, while `nightly-test` makes the bootstrap select `NIGHTLY_TESTS:test-amd-nightly.yml`. Existing `ready` / `merge-test` behavior and non-PR `main` / scheduled builds remain separate. For PR builds without a `DEBUG_TEST_YAML` override, an unreadable label set fails the bootstrap instead of silently selecting the wrong tier. Debug overrides skip label lookup and are validated directly; invalid values, including whitespace-only values, fail the bootstrap.
