154-181: Consider caching the decorated methods.Since the file content rarely changes at runtime, consider caching the results to improve performance.
Apply this diff to add caching:
+ _decorated_methods_cache = {} + @classmethod def decorated_methods(cls, file: str, target: str): + cache_key = f"{file}:{target}" + if cache_key in cls._decorated_methods_cache: + return cls._decorated_methods_cache[cache_key] + try: with open(file, "r") as f: source_code = f.read() tree = ast.parse(source_code) except FileNotFoundError as e: cls().error(f"Could not find file {file}: {e}") return [] except SyntaxError as e: cls().error(f"Could not parse {file}: {e}") return [] keepalive_methods = [] # ... rest of the method ... + cls._decorated_methods_cache[cache_key] = keepalive_methods return keepalive_methodsct-app/core/core.py (1)
399-402: LGTM! Consider adding docstring for the tasks property.The implementation elegantly uses decorators to auto-discover tasks, which aligns with the PR objective. Consider adding a docstring to document the purpose and return type of this property.
@property async def tasks(self): + """ + Discovers and returns a list of methods decorated with 'formalin'. + + Returns: + list: A list of bound methods marked with the 'formalin' decorator. + """ return [getattr(self, method) for method in Utils.decorated_methods(__file__, "formalin")]

19-19: LGTM! Simplified environment variable handling.The removal of the second argument simplifies the parameter handling by using a single environment variable prefix.
23-23: Verify the node credentials handling.The new implementation creates multiple Node instances using list comprehension. While this is more elegant, ensure that:
- The lengths of NODE_ADDRESS and NODE_KEY lists match
- The credentials are properly paired
✅ Verification successful
The node credentials implementation is safe and well-designed
The credentials pairing is handled safely through:
- Consistent ordering via sorted dictionaries
- Matching environment variable prefixes
- Python's zip() handling any potential length mismatches

91-91: LGTM! Consistent test skip message.The whitespace adjustment maintains code formatting consistency.
Line range hint
1-91: Verify test coverage for node initialization.The removal of
test_fromAddressAndKeyListsleaves the new node initialization logic untested. Consider adding a new test that verifies the list comprehension-based node initialization.ct-app/core/node.py (2)
349-351: LGTM! Dynamic task discovery implementation.The property-based implementation elegantly discovers decorated tasks, making the system more maintainable by eliminating the need to manually register new tasks.
53-53: Verify the impact of initial running state.Setting
running = Trueinitially means tasks will start executing immediately upon node creation. Ensure this doesn't cause race conditions with initialization tasks.✅ Verification successful
Initial running state is safely implemented
The code review shows that setting
running = Trueduring initialization is safe because:
- Core initialization completes before the running state is set
- No tasks auto-execute during node creation
- Async operations are independent methods called externally

409-411: LGTM! Clean and efficient task registration.The implementation efficiently aggregates tasks from nodes and core using list comprehensions while maintaining the correct order of operations.
420-420: LGTM! Maintains expected behavior.The stop method correctly maintains the running state management.
62-62: Verify the impact of initializing running state to True.Components are now considered running immediately upon creation, which differs from the previous behavior. Please ensure that tasks and health checks depending on the
runningstate handle this immediate activation correctly.✅ Verification successful
The running state initialization is verified as safe and consistent
The immediate activation of components through
running = Trueis correctly implemented and aligns with the codebase's behavior:
- The change is consistent with Node class initialization
- Task execution through the
formalindecorator works correctly with this state- Components maintain independent control of their running state
- Proper cleanup is preserved through stop methods
