From 12d8ea7efcc7e790b21dd21d298451c9eff4d5c2 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Sun, 2 Nov 2025 07:45:29 -0800 Subject: [PATCH] fix: resolve critical v5.0.0 metadata race condition CRITICAL BUG FIX: TypeAwareStorage metadata race condition Problem: - saveNoun() called before saveNounMetadata() - TypeAwareStorage couldn't determine entity type (not cached yet) - Defaulted to 'thing' and saved to wrong storage path - Later saveNounMetadata() saved to correct path - Noun and metadata in different locations = entity not found Impact: - Broke VFS file operations completely - Broke brain.get(), brain.relate(), brain.find() - All metadata-dependent features failed - Workshop team completely blocked Solution: - Reversed save order: saveNounMetadata() FIRST, then saveNoun() - Type now cached before saveNoun() needs it - Both saved to correct type-aware paths Additional Fixes: - Make baseStorage.initializeCOW() public (was protected) - Remove enableCOW config option (cleanup) - COW auto-init temporarily disabled (deadlock issue) Known Limitations (v5.0.1): - Fork API exists but COW requires manual init - Will be zero-config in v5.1.0 Fixes: Workshop Bug Report (VFS metadata missing) --- CHANGELOG.md | 33 +++++++++++++++++++++++++++++++++ src/brainy.ts | 26 ++++++++++++++++++++------ src/storage/baseStorage.ts | 4 +++- src/storage/storageFactory.ts | 16 ++++++++-------- src/types/brainy.types.ts | 1 - 5 files changed, 64 insertions(+), 16 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 9c199757..0fd525aa 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -2,6 +2,39 @@ All notable changes to this project will be documented in this file.
