From b950df241dd4343d00dd43ef407b1cc04ad18e67 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Fri, 15 Aug 2025 11:48:51 -0700 Subject: [PATCH] fix: Critical production issue - enable remote model downloads by default - Fix embedding system to work out-of-the-box on fresh npm installs - Add proper BRAINY_ALLOW_REMOTE_MODELS environment variable support - Implement smart defaults: remote models enabled by default in production - Add graceful fallback from local-only to remote download - Maintain backward compatibility with existing configurations - Add production readiness test suite for future releases - Provide clear error messages with actionable guidance BREAKING: None - this only improves default behavior FIXES: #critical-production-failure-1.1.0 --- HOTFIX-1.1.1.md | 94 ++++++++++++++++ models/.brainy-models-bundled | 5 - scripts/production-readiness-check.js | 148 ++++++++++++++++++++++++++ src/utils/embedding.ts | 57 +++++++++- 4 files changed, 296 insertions(+), 8 deletions(-) create mode 100644 HOTFIX-1.1.1.md delete mode 100644 models/.brainy-models-bundled create mode 100644 scripts/production-readiness-check.js diff --git a/HOTFIX-1.1.1.md b/HOTFIX-1.1.1.md new file mode 100644 index 00000000..6b69519c --- /dev/null +++ b/HOTFIX-1.1.1.md @@ -0,0 +1,94 @@ +# ๐Ÿšจ CRITICAL HOTFIX: Brainy v1.1.1 + +## **The Problem** +Fresh installations of `@soulcraft/brainy@1.1.0` failed with model loading errors, preventing vector operations from working out-of-the-box. + +## **Root Cause** +The embedding system defaulted to `localFilesOnly: true` in Node.js environments, which prevented automatic model downloads on fresh installations. + +## **The Fix** +**Comprehensive, Multi-Layer Solution:** + +### 1. **Smart Defaults** +- โœ… **Before**: Node.js defaulted to `localFilesOnly: true` (broken for fresh installs) +- โœ… **After**: Node.js defaults to `localFilesOnly: false` (production-friendly) + +### 2. **Environment Variable Support** +- โœ… **New**: `BRAINY_ALLOW_REMOTE_MODELS=true|false` now properly respected +- โœ… **Development**: `NODE_ENV=development` automatically enables remote models + +### 3. **Graceful Fallbacks** +- โœ… **Smart Retry**: If local models fail, automatically attempts remote download +- โœ… **Clear Errors**: Actionable guidance when both local and remote fail +- โœ… **Zero Config**: Works immediately after `npm install` with no setup + +### 4. **Backward Compatibility** +- โœ… **Existing Code**: No changes needed for existing working installations +- โœ… **Explicit Config**: Still honored when provided +- โœ… **Air-Gapped**: Set `BRAINY_ALLOW_REMOTE_MODELS=false` for offline deployments + +## **Impact** + +### **Before (v1.1.0):** +```bash +npm install @soulcraft/brainy +node -e "import {BrainyData} from '@soulcraft/brainy'; const brain = new BrainyData(); await brain.init(); await brain.add('test')" +# โŒ FAILED: local_files_only=true and file was not found locally +``` + +### **After (v1.1.1):** +```bash +npm install @soulcraft/brainy +node -e "import {BrainyData} from '@soulcraft/brainy'; const brain = new BrainyData(); await brain.init(); await brain.add('test')" +# โœ… WORKS: Downloads models automatically and processes data +``` + +## **Deployment Scenarios Now Supported** + +### โœ… **Fresh Installation (Default)** +```bash +npm install @soulcraft/brainy +# Just works -
