"""Functional Tests for Catalog and Bundle Workflows

This test suite validates catalog and bundle management operations that users
depend on for discovering, browsing, and batch-installing MCP servers.

TRACEABILITY TO STATUS AND PLAN:
===============================

STATUS Gaps Addressed:
- "Cannot verify catalog operations work" - All catalog tests
- "Cannot verify bundle installation workflow" - All bundle tests
- "Search functionality untested end-to-end" - test_search_workflow

PLAN Items Validated:
- P0-4: Validate Core Functionality → All workflow tests
- Catalog operations: list, search, add (to local)
- Bundle operations: list, install, verify

TEST PHILOSOPHY:
================
These tests validate END-TO-END workflows from user's perspective:
- User searches for servers in catalog
- User views server details
- User installs bundles of related servers
- User manages custom local catalogs

GAMING RESISTANCE:
==================
Tests cannot be gamed because:
1. Use REAL catalog files (data/catalog.json)
2. Verify ACTUAL search results match expectations
3. Test REAL bundle YAML parsing and installation
4. Check ACTUAL file changes after bundle install
5. Cannot pass with stubs or hardcoded responses
