- AiAssistantService: 90s HTTP timeout; RefineWithCorrections uses 29.99 example price and explicit "Never return 0" instruction; treat returned 0 as missing and keep original price instead - EbayAuthService: shared static HttpClient for all auth/token calls; SemaphoreSlim double-checked locking on GetAppTokenAsync to prevent concurrent token fetches - EbayPriceResearchService: 15s timeout; require ≥5 samples before suggesting; trim top/bottom 10% outliers; BEST_MATCH sort avoids spam/broken listing bias - PhotoAnalysisView: spinner-show inside try (Issue 1); decimal→double casts use Math.Round to avoid 19.99→19.989... drift (Issue 6); Dispatcher.CheckAccess guard for off-thread callers (Issue 7); save toast always restarts instead of silently dropping rapid saves, eliminating any stuck-flag path (Issue 8) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
