-# Observatory (GraphView Minimal, RFC-aligned)
-
+# Observatory 
 A new, review-focused Observatory implementation is available under:
 
 `backends/qualcomm/debugger/observatory`
 
-Key properties:
-1. Uses RFC-style view contracts: `ViewBlock`, `ViewList`, and `GraphView`.
-2. Keeps UI behavior close to legacy observatory while splitting JS into topic files.
-3. Supports ETRecord auto-collection through context-managed monkey patching.
-4. Migrates minimal built-in lenses for v1: metadata and stack trace (plus canonical graph lens).
-
-Quick demo:
+Use observaotry.cli to invoke ordinary aot script. Use `--lens_recipe=accuracy` to enable accuracy Lenses.
