# Changelog

All notable changes to this project are documented in this file.

## 2026-04-12

### Changed
- Improved local development networking by making API env loading work with `.env.local`, adding LAN-friendly API URL fallback behavior, and fixing development CORS handling.
- Fixed local research inserts so nullable Google Places coordinates no longer break business upserts.
- Improved postal data tooling with streaming imports, clearer CRS validation, progress logs, and a status command for checking imported areas and adjacency counts.

### Added
- Added postal-area import and adjacency build scripts for US ZIP/ZCTA and Canada FSA datasets.
- Added a dedicated `Deep Research` view with map pin placement, propagation preview overlays, batch history, and bundled map navigation.
- Added backend deep-research preview, batch creation, and batch detail APIs, reusing the existing research engine to create one child search per postal area.

### Changed
- Migrated the app from a Supabase runtime to a local Fastify API with PostgreSQL, PostGIS, and cookie-based session auth.
- Reworked the research experience with the `Leads4less` branding, the renamed `Research` view, a top-form layout, and a filterable grid of research jobs.
- Added local API wiring for research, dashboard, and map flows while keeping selected-job map behavior and broader lead retrieval support.

### Added
- Added local backend scaffolding under `server/` for auth, health checks, search routes, database access, and worker startup.
