Add canonical recipe deduplication for URL imports#55
Merged
Conversation
Introduce a CanonicalRecipe model to cache extracted recipes by normalized URL, avoiding redundant LLM calls when multiple users import the same recipe. Includes URL normalization, vector similarity indexing, and an ImportFromCanonical endpoint. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

ImportFromURL was returning canonical cache hits without checking FetchedAt against canonicalTTL, unlike PreviewFromURL which enforced the 7-day freshness window. This could serve stale recipe data indefinitely until the 90-day cleanup removed the entry. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Remove DeleteStale and the cleanup goroutine — canonical entries are never deleted. Replace GetHotEntries with GetStaleEntries so the background task refreshes all stale canonicals (not just popular ones), keeping recipe data current when source URLs change.
