From e41ebd40982190be52ffc68979f75c987563e16a Mon Sep 17 00:00:00 2001 From: prosdev Date: Wed, 1 Apr 2026 00:38:36 -0700 Subject: [PATCH 1/3] feat(core,mcp): cached dependency graph for scale Build dependency graph at index time and save as JSON. Load cached graph in dev_map and dev_refs instead of fetching all docs via getAll. Incremental graph updates via file watcher. Falls back to current approach if cache is missing or corrupted.
