- generationRecordClient.ts: Enhance save deduplication with payload signature — replace simple recordId-based dedup with stableJsonStringify-based signature comparison; same recordId + same signature skips save, changed payload proceeds; add buildSaveSignature covering tool/mode/title/status/prompt/taskIds/assets/config/result/metadata; store signature alongside savedAt in recentlySavedRecords map for per-turn save accuracy
- EcommercePage.tsx: Introduce EcommerceHistoryTurn interface and multi-turn conversation architecture —
- Add EcommerceHistoryTurn with full generation context (status/output/platform/market/language/ratio/requirement/images/results/counts/modules/scenes/replicateLevel); EcommerceHistoryRecord gains status/errorMessage/turns[] fields
- beginEcommerceHistoryTurn() — start a new generation turn, create or append to record, persist to localStorage immediately
- updateLocalEcommerceHistoryTurn() — real-time turn status sync (generating→done/failed) with record summary mirroring via syncRecordSummaryWithTurn()
- restoreHistoryTurnInputs() — one-click parameter restoration from failed turns for retry
- upsertCanvasNode() — insert or update canvas node by ID (dedup by turnId), alternating row layout (x: index*420, y: 0 or 160)
- Generate flow wired to turns: status callbacks update turn state; cancel sets turn to failed; results written to turn.results
- Record detail conversation panel refactored from single-message to per-turn iteration — each turn renders user message (requirement + meta + assets) and assistant message (status-aware text + progress bar during generation + result thumbnails); failed turns show "恢复参数" retry button; generating turn shows EcommerceProgressBar
- openEcommerceHistoryRecord() loads all turns as canvas nodes with distributed positions; preserves generating turn tracking via activeHistoryTurnIdRef
- History list items display status label (生成中/失败/time)
- Product set preview backdrop moved to createPortal(document.body) with z-index 4000
- pages/ecommerce.css: Bump product-set-preview-backdrop z-index from 100 to 4000 for Portal rendering layer
