+## 2026-10-05 — Composite device source images
+
+### Requested
+- Lars asked for the untracked source images in the local checkout to be committed, and whether `main` needs a new Homey build.
+
+### Implemented
+- `assets/images_composite_device/source.svg`: added unchanged.
+- `assets/composite_device/source.png`: added with unchanged content. The original file name named the image generator, so it is renamed in the same way as the other source images in #59 and #60.
+- `.homeyignore` already excludes both paths (`assets/composite_device/` and `assets/images_composite_device/source.svg`), so the app bundle is unchanged.
+- New build: not needed. The published 1.10.32 changelog covers #52–#55. Since #55, only files outside the app bundle have changed (tests, docs, coverage, ignore patterns, source images), plus the version metadata that matches the published build.
+
+### Not changed
+- The local log folder from earlier development runs (runtime logs, monitor state and process files) is still untracked, pending Lars's decision.
+- `source.png` still carries the generator's embedded content-credential metadata. Only the file name changed.
+
+### Verification
+- SHA-256 of both committed files matches the originals.
+
 ## 2026-10-05 — Test v1.10.32 released and local cleanup
