Closes the last two findings from the 2026-06-02 audit (G5.1 + G5.4). G5.1 — Centroid version no longer drifts: CentroidService now reads MLSettings.embedder_model_version (the DB row tag_and_embed already writes from) for both the centroid model- version stamp and the drift-detection comparison. Previously the centroid sites imported MODEL_VERSION from env, so the version stamped on centroids could disagree with the version stamped on the embeddings they were built from. By construction those now match, so list_drifted won't silently miss the env-vs-DB drift case. embedder.py keeps MODEL_VERSION as an env-driven constant for the actual model loader — that's a different concern (which weights are loaded) from the version-stamp that gets persisted alongside data. G5.4 — Modal is a Pinia-only overlay: The previous URL↔modal sync in GalleryView and ArtistGalleryTab leaked the modal across route changes (RouterLink to /artist/<slug> left the modal mounted on top of the new route) and re-opened it on history back/forward with stale ?image=N entries. Now: openImage() just calls modal.open(id) — no URL push. GalleryView's dead closeImage helper is deleted. A route.name watcher in App.vue closes the modal whenever the route changes, which auto-fixes RouterLink-in-modal and back/forward. Backward-compat: ?image=N is still honored on initial mount as a one-shot deep-link opener, then router.replace strips the query so the URL doesn't re-trigger and no extra history entry is added. Existing bookmarks / shared URLs keep working; new opens stay Pinia-only.
