  • Branch: fix/resource-registry-dag-type-ignore-override

  • Milestone: v3.7.0
  • Parent Epic: #2810

Bug Report

Background

The file src/cleveragents/application/services/_resource_registry_dag.py contains two # type: ignore[override] inline comments on the link_child and unlink_child method definitions (lines 47 and 157). This directly violates the project's strict no-suppression policy.

Per CONTRIBUTING.md:

 "Under no circumstances should type checking be ignored — never modify configuration files to disable it, and never use inline comments (such as # type: ignore) to suppress type checking errors."

Files Affected

  • src/cleveragents/application/services/_resource_registry_dag.pyResourceDagMixin.link_child() (line 47) and ResourceDagMixin.unlink_child() (line 157)

Current Behavior

Two # type: ignore[override] comments exist in the ResourceDagMixin class, suppressing Pyright override-checking errors:

def link_child(
    self: RegistryHost, parent_name_or_id: str, child_name_or_id: str
) - None:  # type: ignore[override]

and

def unlink_child(
    self: RegistryHost, parent_name_or_id: str, child_name_or_id: str
) - None:  # type: ignore[override]

The root cause is a mixin pattern where the self: RegistryHost Protocol type annotation conflicts with Pyright's override checking. Because the mixin uses a narrowed self type (a Protocol) rather than the class itself, Pyright cannot verify that the override is valid and raises an error — which has been silenced with # type: ignore[override] instead of being properly fixed.

Expected Behavior

Per CONTRIBUTING.md, the code must be refactored so that Pyright accepts it without any type suppression. The mixin/protocol relationship must be restructured so that:

  1. The self type annotation on link_child and unlink_child is compatible with Pyright's override checking rules.
  2. No # type: ignore comments of any kind are present in the file.
  3. nox -e typecheck passes cleanly with zero errors or suppressions.

Steps to Reproduce

  1. Run nox -e typecheck
  2. Observe that the # type: ignore[override] comments suppress errors that should be fixed
  3. Remove the two # type: ignore[override] comments and re-run nox -e typecheck to see the underlying Pyright errors

Impact

  • Severity: Medium — violates mandatory code quality standards; may hide real type errors in the resource registry DAG mixin
  • Scope: _resource_registry_dag.pyResourceDagMixin.link_child() and ResourceDagMixin.unlink_child()
  • Risk: The suppressed errors may be masking a genuine type unsafety in the mixin pattern that could lead to runtime errors if the mixin is applied to an incompatible class

Subtasks

  • Reproduce the underlying Pyright error by removing the two # type: ignore[override] comments and running nox -e typecheck
  • Analyse the ResourceDagMixin / RegistryHost Protocol relationship to understand why Pyright raises an override error
  • Refactor the mixin/protocol pattern so that Pyright accepts the override without suppression (e.g. use @override decorator correctly, adjust Protocol definition, or restructure inheritance)
  • Remove both # type: ignore[override] comments from _resource_registry_dag.py
  • Verify nox -e typecheck passes with zero errors and zero suppressions
  • nox -e unit_tests passes (no regressions from the refactor)
  • Verify nox -e coverage_report reports coverage = 97%
  • Update or add Behave unit-test scenarios in features/ if the refactor changes observable behaviour
  • Commit with the conventional commit message specified in Metadata

Definition of Done

  • Both # type: ignore[override] comments are removed from _resource_registry_dag.py
  • nox -e typecheck passes with zero errors and zero suppressions
  • nox -e unit_tests passes with no regressions
  • nox -e coverage_report reports coverage = 97%
  • No new # type: ignore comments introduced anywhere in the codebase
  • PR is opened, reviewed, and merged targeting the parent Epic branch or master
  • All nox stages pass
  • Coverage = 97%

Starting implementation on branch fix/resource-registry-dag-type-ignore-override.

Analysis: The two # type: ignore[override] comments on link_child (line 47) and unlink_child (line 157) in _resource_registry_dag.py were unnecessary suppressions. After removing them, nox -e typecheck passes with 0 errors — confirming the underlying type system is already correct and the suppressions were masking nothing real.

Fix: Simply removed both # type: ignore[override] comments. No structural refactoring needed.

Quality gates:

  • nox -e typecheck — 0 errors, 0 warnings, 0 informations

All subtasks complete. Creating PR.
