86-86: Consider addressing resource tracker initializationWhile this fix properly handles undefined cases, consider if resource trackers should be guaranteed to exist through proper initialization at the data layer. This would provide stronger invariants and might prevent similar issues elsewhere.

Line range hint 39-42: Verify query behavior with undefined trackers
While the direct access is now protected, let's verify how the NotValue query operator handles undefined cases.
✅ Verification successful
Based on the search results, I can now generate the final response:
NotValue operator usage is consistent and safe
The NotValue operator is consistently used across the codebase in similar patterns, particularly with default/zero values:
- For OwnedResourcesTracker:
{ resource_types: 0n } - For Army:
{ battle_id: 0 } - For Building:
{ entity_id: 0 }
This pattern indicates it's a standard way to handle undefined cases by checking against default/zero values, making the query in use-resource-arrivals.tsx follow established practices.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Look for similar query patterns to understand standard usage
rg -B 2 -A 2 'NotValue.*OwnedResourcesTracker'
# Check for any related tests
fd -e test.tsx -e test.ts -e spec.tsx -e spec.ts | xargs rg 'OwnedResourcesTracker'
Length of output: 949
Script:
#!/bin/bash
# Let's check the implementation of NotValue operator and its handling of undefined cases
ast-grep --pattern 'NotValue($_, $_)'
# Also check for any documentation or type definitions related to NotValue
rg -B 2 -A 2 'NotValue'
Length of output: 5170
86-86: LGTM! Good defensive programming.
The addition of the truthy check !!ownedResourceTracker fixes the potential undefined error when accessing resource_types. This makes the code more robust and prevents UI breaks when resource trackers are not yet initialized.
Let's verify that this is the only place needing such protection:
✅ Verification successful
No other unsafe resource tracker accesses found
Based on the verification results, the added null check in use-resource-arrivals.tsx is the only place where resource_types is directly accessed from a potentially undefined tracker. Other usages are either in type definitions, component queries, or initialization code where the tracker is guaranteed to exist.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Search for other potentially unsafe resource tracker accesses
ast-grep --pattern 'OwnedResourcesTracker.$_'
Length of output: 151
Script:
#!/bin/bash
# Let's try a different pattern to find resource tracker usages
rg -A 2 "resource_types.*0n"
Length of output: 1046
Script:
#!/bin/bash
# Let's search for all direct accesses to resource_types property
ast-grep --pattern '$_.resource_types'
Length of output: 295
