- Database now contains 499 templates (was 399)
- FTS5 index properly populated with all template entries
- Fixed quote escaping in FTS5 queries to prevent syntax errors
- Verified FTS5 search returns correct results (162 for "webhook")
- Fixes template search in Docker deployments
The previous database had empty FTS5 tables causing search to fail.
This update ensures the FTS5 index is properly synchronized and
handles special characters in search queries.

- Add FTS5 pre-creation in fetch-templates.ts before data import
- Create prebuild-fts5.ts script to ensure FTS5 tables exist
- Improve logging in template-repository.ts for better debugging
- Add npm script 'prebuild:fts5' for manual FTS5 setup
This ensures template search works consistently in Docker mode
where runtime FTS5 table creation might fail due to permissions.

- Added runtime FTS5 detection in database adapters
- Removed FTS5 from required schema to prevent "no such module" errors
- FTS5 tables/triggers created conditionally only if supported
- Template search automatically falls back to LIKE when FTS5 unavailable
- Works in ALL SQLite environments (Claude Desktop, restricted envs, etc.)
This ensures search_templates() works correctly regardless of SQLite build,
while still providing optimal performance when FTS5 is available.

Critical fixes based on Claude Desktop feedback:
1. Fixed crypto documentation: require('crypto') IS available despite editor warnings
- Added clear examples of crypto usage
- Updated validation to guide correct require() usage
2. Clarified $helpers vs standalone functions
- $getWorkflowStaticData() is standalone, NOT $helpers.getWorkflowStaticData()
- Added validation to catch incorrect usage (prevents '$helpers is not defined' errors)
- Enhanced examples showing proper $helpers availability checks
3. Fixed JMESPath numeric literal documentation
- n8n requires backticks around numbers in filters: [?age >= `18`]
- Added multiple examples and validation to detect missing backticks
- Prevents 'JMESPath syntax error' that Claude Desktop encountered
4. Fixed webhook data access gotcha
- Webhook payload is at items[0].json.body, NOT items[0].json
- Added dedicated 'Webhook Data Access' section with clear examples
- Created process_webhook_data task template
- Added validation to detect incorrect webhook data access patterns

Root cause: AI agents were placing error handling properties inside `parameters` instead of at node level
Major changes:
- Enhanced workflow validator to check for ALL node-level properties (expanded from 6 to 11)
- Added validation for onError property values and deprecation warnings for continueOnFail
- Updated all examples to use modern error handling (onError instead of continueOnFail)
- Added comprehensive node-level properties documentation in tools_documentation
- Enhanced MCP tool documentation for n8n_create_workflow and n8n_update_partial_workflow
- Added test script demonstrating correct node-level property usage
Node-level properties now validated:
- credentials, disabled, notes, notesInFlow, executeOnce
- onError, retryOnFail, maxTries, waitBetweenTries, alwaysOutputData
- continueOnFail (deprecated)
Validation improvements:
- Detects misplaced properties and provides clear fix examples
- Shows complete node structure when properties are incorrectly placed
- Type validation for all node-level boolean and string properties
- Smart error messages with correct placement guidance

Fixed issue where Docker images using sql.js adapter returned boolean fields
as strings, causing is_trigger=0 to evaluate as true instead of false.
Changes:
- Added convertIntegerColumns() to sql.js adapter to convert SQLite integers
- Updated server.ts and node-repository.ts to use Number() conversion as backup
- Added test script to verify fix works with sql.js adapter
This fixes webhook, cron, interval, and emailReadImap nodes showing
isTrigger: false in Docker deployments.

- Added no-cache: true to docker/build-push-action
- Previous builds were aggressively caching the old database from 13:18
- This forces a complete rebuild including the new database with trigger fixes
- Build will take longer (5-10min vs 26sec) but ensures correct database
The cache was so aggressive that even Dockerfile changes didn't invalidate it.
This nuclear option ensures the trigger detection fixes for webhook, cron,
interval, and emailReadImap nodes are finally included in the Docker image.

- Added cache-busting comment to invalidate Docker's build cache
- Previous builds were using cached COPY layer with old database from 13:18
- This ensures Docker copies the new database (15:38) with is_trigger=true fixes
- Affects: webhook, cron, interval, emailReadImap nodes
The Docker build cache was serving an old database without the trigger detection fix,
causing these nodes to incorrectly show isTrigger: false in the MCP tool.

- Added 'lfs: true' to all checkout steps in workflows
- Ensures Docker builds get the actual database file, not LFS pointer
- Required after migrating nodes.db to Git LFS
- Moved nodes.db to Git LFS to avoid push protection issues
- Database has been sanitized to remove all API tokens
- This allows the database to be included in repository for Docker builds
- Update rebuild script to automatically sanitize templates after node processing
- Update documentation to reflect GitHub push protection changes
- Add notes about template sanitization in n8n update process
- Ensures databases are always clean before push
This prevents GitHub push protection from blocking database updates
due to API tokens in workflow templates.
