+The previous section's next action: a layered parallax source, then match-3 gems. One
+commit, `5bd86a1`. Entry count 315 to 319 (2D 54). **Both new task tests now pass.**
+
+- Added, each archive downloaded to measure it and to read any bundled licence:
+  `ansimuz-industrial-parallax` and `gustavo-saraiva-city-parallax` (publisher-stated
+  parallax layers, both CC0), `bondoki-rotating-gems` and `sylly-gem-match-3` (match-3
+  gems, both CC0). The two parallax sets carry `camera_perspective: side_scroller`.
+- **New lesson, from a rejected candidate:** GrumpyDiamond's Parallax Mountain Background
+  shows CC0 on its OpenGameArt page, but the licence file inside its download says
+  "cc-BY-3.0" and asks for credit. Not added. The OGA licence field is the uploader's
+  claim; a bundled licence file can contradict it, and only opening the archive shows
+  that. Every OGA entry added in this session had its archive opened; older OGA entries
+  were not, and are worth the same check.
+- Also rejected: CraftPix's OGA parallax sets (OGA-BY 3.0, credit required, and listed as
+  teasers for paid packs) and "3 Parallax Backgrounds" (GPL 3.0, which is a poor fit for
+  art in a closed game).
+- `publisher` left unset on the four OGA entries: two existing opengameart.org entries
+  carry `publisher: OpenGameArt`, and V7 requires one publisher per domain.
+- Next highest-value action: **open the archives of the older OpenGameArt entries** and
+  compare any bundled licence file with the licence field, following the GrumpyDiamond
+  finding. The OGA entries added before today were checked against the page only. Then
+  the third MODE=full review on or after 2026-10-17.

+- Next highest-value action: ~~**a layered parallax background source**~~ Done in the
+  parallax and gems section above, with match-3 gems. The one leave
   point left from task D. Look for a publisher-stated CC0 or CC-BY set of separate
   background layers; if none states it, record the gap rather than tagging a pack on a
   commenter's word. After that, match-3 gem art for task E.
