+- **Major design change surfaced mid-approval (operator, 2026-06-04):** switch to
+  a **single panoramic projector spanning all three walls, content = nature
+  videos**, and "we may not need any video manipulation at all." This supersedes
+  the design spec §6 (four projectors) / §7 (procedural side walls) and reshapes
+  sub-projects 3 (player → one pano output) and 5 (side walls likely dropped).
+  **Handled in this spec** by demoting `dominant_color` to optional/opt-in (its
+  only consumer was the side walls). **Follow-up for the operator:** the design
+  spec + ROADMAP need a separate update pass to reflect the pano/nature-video
+  direction — out of scope for the sub-project-2 spec. Captured in memory.
+- Operator confirmed first-ship archives (LibriVox + NASA + IA) and approved the
+  spec "as written"; remaining §11 defaults (file_path relative-to-root, two
+  `python -m` CLIs, `index_by_id` in hef.catalog) taken as accepted.
