From e5f5de4e6420f37cfadc6500a259b31c5d0ad47d Mon Sep 17 00:00:00 2001 From: jedarden Date: Mon, 25 May 2026 14:50:38 -0400 Subject: [PATCH] feat(cmd): add acb-maps-loader to load map library into database - New cmd/acb-maps-loader reads all 200 map JSON files from maps/ directory - Transforms map files into database schema format for maps table - Supports INSERT with ON CONFLICT for idempotent updates - Includes tests verifying all 200 maps can be parsed - Updates Makefile with acb-maps-loader and load-maps targets This addresses the plan-gap where maps/ had 200 maps but only 12 were in the database. The index-builder generates maps/index.json from the database, so loading the full map library enables complete map index generation.
