From d4c4750488c27006daaaabec57b69f092371126d Mon Sep 17 00:00:00 2001 From: Matt Johnson Date: Mon, 18 May 2026 04:36:32 +0000 Subject: [PATCH] feat(gui): add events feed frontend with map and filters GET /events: Full page with filter form, table, and Leaflet map GET /events/rows: HTMX fragment for table updates Features: - Filterable by adapter, category, time range, region bbox - Cursor-based pagination with Next button - Leaflet map showing event geometries - Click/hover row highlights geometry on map - Draw rectangle on map to filter by region - Validation errors shown as banner, not 400 - Events link added to nav between Adapters and Streams Refactored events query into shared helper for JSON and HTML routes. Tests: 14 new tests covering filters, fragments, geometry handling.
