Changelog

Expanded catalog export to support eBay, Amazon, BigCommerce, and Google Shopping channels with per-channel column mappings and validated CSV output.

Added a Tutorials section for onboarding walkthroughs, a live Status page for monitoring service health, and an upload-health diagnostic endpoint.

Shipped the Affiliate page for managing partnership sign-ups and promotions, laying the groundwork for referral-based growth.

Launched the Bug Swatter page with a user-friendly bug report form and a rewards program to incentivize the community to surface issues early.

Built an admin dashboard tracking the last 200 category picks with average AI confidence scores and low-confidence alerts to continuously improve suggestion accuracy.

Released the Tweaker tool for batch product adjustments. Supports multi-channel column definitions (eBay, Amazon, BigCommerce, Google Shopping) and a streamlined editing UI.

Added the Projects module to organize products into groups. Includes project listing, detail views, and catalog-to-project sync via a dedicated API endpoint.

Introduced AI-powered bulk product creation using GPT-4o Vision. The system detects numbered labels in images, validates sequential order, auto-increments SKUs, and tracks progress in a real-time modal. Supports up to 48 images per batch.

Launched the Orders module with eBay order sync, import run history, individual order detail views, deduplication, shipping lookup, sales summaries, and settlement download.

Shipped ML-based eBay category suggestions with full-text search across the category tree, confidence scoring, feedback loop for training, and a toggleable picker UI.

Created a centralized CSV utility library with SKU sanitization, RFC 4180 escaping, and description normalization. Fixed invalid characters, broken newlines, and improper quoting in SellerCloud exports.

Built the Settings page for storing eBay credentials and toggling controls for order download, fulfillment upload, inventory sync, and pricing. Added payment, shipping, and return policy management.

Fixed silent failures on large uploads by increasing the request body limit to 50 MB, extending timeout to 5 minutes, and batching image uploads 20 at a time.

Replaced inline data-URL storage with a proper upload pipeline: images are now uploaded to Firebase Storage first, then permanent URLs are saved to Firestore. Eliminated data-URL bloat.

Launched the Generate Products page with single and multi-product modes, an in-memory reviewer queue, and one-click "Add to Catalog" batch action that writes products to Firestore.

Migrated catalog to user-scoped storage with document IDs formatted as {email}__{sku}. Each seller now has isolated product data with no cross-user SKU collisions.

Added Google OAuth as an alternative sign-in method alongside email/password, with automatic account linking and session management.

Configured Firebase App Hosting, deployment scripts, and apphosting.yaml to publish the production app.

Created the /changelog page and reusable ChangelogCard component to surface major milestones as a visual feed.

Added a real-time LiveWasteCounter showing pro-rated dollar figures for total waste and reclaimed amounts on the homepage.

Designed and implemented the dynamic MatrixHero canvas component and HomeHeroWrapper layout for the landing page.

Connected to the eBay API with OAuth, item aspects normalization, and category helpers for listing management.

Launched the product catalog with listing view, item specifics editor, CSV/XLSX import, and multi-image management per product.

Built email/password login, HTTP-only cookie sessions (5-day expiry), and route-level middleware protecting /catalog, /tweaker, and other user routes.

Integrated Firebase Admin SDK, client config, and Firestore helpers for auth and data storage powering items and user sessions.

Created the initial Next.js + TypeScript app scaffold, repo structure, README, and core scripts to establish the project foundation.
