* fix(items): retry failed model loads, settle skipped items, keep exports clean A transient storage failure (observed: Supabase 504s under the bake page's ~200-concurrent-request burst) permanently broke an item for the whole session: drei's useGLTF caches the rejected load by URL, the per-item ErrorBoundary swallowed it, and the red debug-box fallback was BAKED into the exported GLB (observed in a prod artifact). Meanwhile ItemSystem cleared the dirty mark at group registration — before the model resolved — so scene-ready could fire while GLBs were still loading, risking exported placeholder geometry. - ModelWithRetry: bounded retries (1s/3s) that clear the useGLTF cache entry and re-mount via the boundary's new resetKey. The timer is owned by an effect keyed on the failure count, so StrictMode's synthetic unmount/remount re-arms it instead of silently discarding it (the naive onError-scheduled timer died exactly that way in dev). - Exhausted retries settle the item as SKIPPED: the debug box renders nothing during exports, and the failure lands in useViewer.itemLoadFailures (nodeId -> url) so a bake host can persist which items are missing from the artifact. - ItemSystem holds the dirty mark until the item settles (model mounted, terminally failed, or never expected) — scene-ready now genuinely waits for item content; loading placeholders also hide during exports. - ErrorBoundary: onError + resetKey props. Verified against a 200+-item prod scene locally: permanent 504 -> exactly 3 fetch attempts, bake completes without the item and without debug boxes; 504-once -> retry heals, artifact byte-equivalent to the intact run; no-failure runs unchanged (demo_1 byte-identical). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(items): reset retry budget + settled flag when the asset URL changes Bugbot: after a terminal load failure, swapping the item's model kept the stale failures/epoch state and the settled flag — the new URL never even attempted to load. ModelWithRetry is now keyed by asset src (clean retry budget per URL) and un-settles the item on mount so the replacement load is awaited by ItemSystem/scene-ready too.
