de2abaf89d refactor: streamline test suite — 33 fewer files, 11.9x faster (#670) 
* refactor: streamline test suite - cut 33 files, enable parallel execution (11.9x speedup)

Remove duplicate, low-value, and fragmented test files while preserving
all meaningful coverage. Enable parallel test execution and remove
the entire benchmark infrastructure.

Key changes:
- Consolidate workflow-validator tests (13 files -> 3)
- Consolidate config-validator tests (9 files -> 3)
- Consolidate telemetry tests (11 files -> 6)
- Merge AI validator tests (2 files -> 1)
- Remove example/demo test files, mock-testing files, and already-skipped tests
- Remove benchmark infrastructure (10 files, CI workflow, 4 npm scripts)
- Enable parallel test execution (remove singleThread: true)
- Remove retry:2 that was masking flaky tests
- Slim CI publish-results job

Results: 224 -> 191 test files, 4690 -> 4303 tests, 121K -> 106K lines
Local runtime: 319s -> 27s (11.9x speedup)

* refactor: absorb config-validator satellite tests into consolidated file

The previous commit deleted 4 config-validator satellite files. This
properly merges their unique tests into the consolidated config-validator.test.ts,
recovering 89 tests that were dropped during the bulk deletion.

Deduplicates 5 tests that existed in both the satellite files and the
security test file.

* fix: delete missed benchmark-pr.yml workflow, fix flaky session test

- Remove benchmark-pr.yml that referenced deleted benchmark:ci script
- Fix session-persistence round-trip test using timestamps closer to
  now to avoid edge cases exposed by removing retry:2

* fix: rebuild FTS5 index after database rebuild to prevent stale rowid refs

The FTS5 content-synced index could retain phantom rowid references from
previous rebuild cycles, causing 'missing row N from content table'
errors on MATCH queries.

- Add explicit FTS5 rebuild command in rebuild script after all nodes saved
- Add FTS5 rebuild in test beforeAll as defense-in-depth
- Rebuild nodes.db with consistent FTS5 index

* fix: use recent timestamps in all session persistence tests

Session round-trip tests used timestamps 5-10 minutes in the past which
could fail under CI load when combined with session timeout validation.
Use timestamps 30 seconds in the past for all valid-session test data.

c2dc7c9c51 feat: configurable MAX_SESSIONS via N8N_MCP_MAX_SESSIONS env var (v2.28.4) (#469) 
* fix: n8n_test_workflow webhookId resolution and form handling (v2.28.2)

## Bug Fixes

- **webhookId Resolution**: Fixed trigger handlers using `node.id` instead of
  `node.webhookId` for building webhook URLs. This caused 404 errors when
  nodes had custom IDs.

- **Chat Trigger URL**: Fixed chat triggers using wrong URL pattern. Now
  correctly uses `/webhook/<webhookId>/chat` endpoint.

- **Form Content-Type**: Fixed form triggers failing with "Expected
  multipart/form-data" error by switching to proper multipart encoding.

## Enhancements

- **Form Field Types**: Added support for all n8n form field types (text,
  textarea, email, number, password, date, dropdown, checkbox, file, hidden)

- **Checkbox Arrays**: Automatically converts arrays to `field[]` format

- **Helpful Warnings**: Reports missing required fields with names and labels

- **Error Hints**: Provides complete field structure on failure

05424f66af feat: Session Persistence API for Zero-Downtime Deployments (v2.24.1) (#438) 
* feat: Add session persistence API for zero-downtime deployments (v2.24.1)

Implements export/restore functionality for MCP sessions to support container
restarts without losing user sessions. This enables zero-downtime deployments
for multi-tenant platforms and Kubernetes/Docker environments.

New Features:
- exportSessionState() - Export active sessions to JSON
- restoreSessionState() - Restore sessions from exported data
- SessionState type - Serializable session structure
- Comprehensive test suite (22 tests, 100% passing)

Implementation Details:
- Only exports sessions with valid n8nApiUrl and n8nApiKey
- Automatically filters expired sessions (respects sessionTimeout)
- Validates context structure using existing validation
- Handles null/invalid sessions gracefully with warnings
- Enforces MAX_SESSIONS limit during restore (100 sessions)
- Dormant sessions recreate transport/server on first request

Files Modified:
- src/http-server-single-session.ts: Core export/restore logic
- src/mcp-engine.ts: Public API wrapper methods
- src/types/session-state.ts: Type definitions
- tests/: Comprehensive unit tests

Security Note:
Session data contains plaintext n8n API keys. Downstream applications
MUST encrypt session data before persisting to disk.

* feat: implement 7 critical session persistence API fixes for production readiness

This commit implements all 7 critical fixes identified in the code review
to make the session persistence API production-ready for zero-downtime
container deployments in multi-tenant environments.

Fixes implemented:
1. Made instanceId optional in SessionState interface
2. Removed redundant validation, properly using validateInstanceContext()
3. Fixed race condition in MAX_SESSIONS check using real-time count
4. Added comprehensive security logging with logSecurityEvent() helper
5. Added duplicate session ID detection during export with Set tracking
6. Added date parsing validation with isNaN checks for Invalid Date objects
7. Restructured null checks for proper TypeScript type narrowing

Changes:
- src/types/session-state.ts: Made instanceId optional
- src/http-server-single-session.ts: Implemented all validation and security fixes
- tests/unit/http-server/session-persistence.test.ts: Fixed MAX_SESSIONS test

All 13 session persistence unit tests passing.
All 9 MCP engine session persistence tests passing.
