## Problem
PR #309 added `main`, `types`, and `exports` fields to package.json for library usage,
but v2.18.9 was published without these fields. The publish scripts (both local and CI/CD)
use package.runtime.json as the base and didn't copy these critical fields.
Result: npm package broke library usage for multi-tenant backends.
## Root Cause
Both scripts/publish-npm.sh and .github/workflows/release.yml:
- Copy package.runtime.json as base package.json
- Add metadata fields (name, bin, repository, etc.)
- Missing: main, types, exports fields
## Changes
### 1. scripts/publish-npm.sh
- Added main, types, exports fields to package.json generation
- Removed test suite execution (already runs in CI)
### 2. .github/workflows/release.yml
- Added main, types, exports fields to CI publish step
### 3. Version bump
- Bumped to v2.18.10 to republish with correct fields
## Verification
✅ Local publish preparation tested
✅ Generated package.json has all required fields:
- main: "dist/index.js"
- types: "dist/index.d.ts"
- exports: { "." : { types, require, import } }
✅ TypeScript compilation passes
✅ All library export paths validated
## Impact
- Fixes library usage for multi-tenant deployments
- Enables downstream n8n-mcp-backend project
- Maintains backward compatibility (CLI/Docker unchanged)

CRITICAL BUG FIX:
NodeTypeNormalizer.normalizeToFullForm() converts TO SHORT form (nodes-langchain.*),
but all validation code compared against FULL form (@n8n/n8n-nodes-langchain.*).
This caused ALL AI validation to be silently skipped.
Impact:
- Missing language model detection: NEVER triggered
- AI tool connection detection: NEVER triggered
- Streaming mode validation: NEVER triggered
- AI tool sub-node validation: NEVER triggered
ROOT CAUSE:
Line 348 in ai-node-validator.ts (and 19 other locations):
if (normalizedType === '@n8n/n8n-nodes-langchain.agent') // FULL form
But normalizedType is 'nodes-langchain.agent' (SHORT form)
Result: Comparison always FALSE, validation never runs
FIXES:
1. ai-node-validator.ts (7 locations):
- Lines 551, 557, 563: validateAISpecificNodes comparisons
- Line 348: checkIfStreamingTarget comparison
- Lines 417, 444: validateChatTrigger comparisons
- Lines 589-591: hasAINodes array
- Lines 606-608, 612: getAINodeCategory comparisons
2. ai-tool-validators.ts (14 locations):
- Lines 980-991: AI_TOOL_VALIDATORS keys (13 validators)
- Lines 1015-1037: validateAIToolSubNode switch cases (13 cases)
3. ENHANCED streaming validation:
- Added validation for AI Agent's own streamResponse setting
- Previously only checked streaming FROM Chat Trigger
- Now validates BOTH scenarios (lines 259-276)
VERIFICATION:
- All 25 AI validator unit tests: ✅ PASS
- Debug test (missing LM): ✅ PASS
- Debug test (AI tools): ✅ PASS
- Debug test (streaming): ✅ PASS
Resolves:
- HIGH-01: Missing language model detection (was never running)
- HIGH-04: AI tool connection detection (was never running)
- HIGH-08: Streaming mode validation (was never running + incomplete)

Bug Fixes:
- Removed MSW from integration test setup (was blocking real API calls)
- Fixed .env loading order to preserve real credentials over test defaults
- Added type guards for undefined workflow IDs
- Fixed position arrays to use proper tuple types [number, number]
- Added literal types for executionOrder and settings values
Test Coverage:
- P0: Critical bug verification (FULL vs SHORT node type format)
- P1: Base n8n nodes (webhook, HTTP, langchain, multi-node)
- P2: Advanced features (connections, settings, expressions, error handling)
- Error scenarios (documents actual n8n API validation behavior)
- Edge cases (minimal workflows, empty connections, no settings)
Technical Improvements:

- Enhanced workflow validator to enforce typeVersion on versioned nodes
- Returns errors for missing typeVersion with suggested version to add
- Warns about outdated typeVersion values
- Prevents invalid typeVersion (zero, negative, or exceeding maximum)
- Added comprehensive test script for typeVersion validation
- Helps AI agents avoid common workflow creation mistakes
This ensures workflows always use compatible node versions before deployment.

Major optimization that reduces Docker image size by 87% and build time by 10x:
- Remove ALL n8n dependencies from runtime Docker image
- Add package.runtime.json with only 5 essential runtime deps
- Optimize Dockerfile to build TypeScript without n8n packages
- Add BuildKit optimizations with cache mounts
- Update documentation to highlight the improvements
Results:
- Image size: ~1.5GB → ~200MB (87% reduction)
- Build time: ~12 minutes → ~1-2 minutes
- No n8n version conflicts at runtime
- Better security with minimal attack surface
The key insight is that since we always rebuild the database locally
before deployment, the Docker runtime never needs n8n packages.
