heat-system-legacy-dimension
Platform reserved (system-utils only). Persists v1 facade JSON (top-level keys such as Map, stats-summary, combined-custom-charts) and creates a dimension with DashboardVersion="Legacy" for ui/legacy.
When to use it
Use for legacy dashboard samples or migrations that still consume v1 payload keys. Prefer Next paths for new work.
Limitations
- Does not accept
$heat-dataservice(use heat-system-next-dimension for Next). - Layout keys are stripped from the S3 blob; layout lives on the dimension row per the v1 model.
