Summary

  • replace flattened repository-to-runner access with repository-to-org-runner-group GH_CanUseRunner edges
  • add traversable GH_HasRunner edges for direct organization and enterprise runner group membership
  • make GH_InheritedFrom traversable and remove redundant runner-group GH_GrantsAccessTo / GH_AssignedTo edges
  • update runner/repository queries, extension schema, descriptions, and tests for the new path shape

Testing

  • UV_CACHE_DIR=/tmp/uv-cache uv run pytest tests/test_runner_models.py tests/test_runner_resources.py tests/test_runner_ids.py
  • UV_CACHE_DIR=/tmp/uv-cache uv run ruff check src/openhound_github/kinds/edges.py src/openhound_github/models/runner.py src/openhound_github/models/repository.py tests/test_runner_models.py
  • git diff --check

Notes

  • GH_CanUseRunner remains non-traversable in this change because it currently models repository eligibility from visibility / selected-repository policy / allows_public_repositories only; workflow restrictions are still represented as runner-group properties and can be modeled separately.

Summary by CodeRabbit

  • Documentation

    • Clarified runner groups, inheritance, enterprise team assignments, and repository eligibility.
    • Distinguished policy-based eligibility from workflow dispatch access.
  • New Features

    • Added traversable runner membership, inheritance, and repository-creation access relationships.
    • Expanded runner discovery across organization and enterprise groups, including branches.
    • Added policy-aware workflow dispatch modeling.
  • Bug Fixes

    • Corrected runner visibility and inheritance behavior.
    • Restricted access according to Actions and workflow policies.
    • Removed outdated runner access relationships.

Replace the flattened runner access model with explicit runner-group hops. Repository eligibility now terminates at the organization-facing runner group via GH_CanUseRunner, while GH_HasRunner captures direct group-to-runner exposure for organization and enterprise runners.

Make GH_InheritedFrom traversable so inherited organization runner groups bridge naturally to enterprise runner groups. Remove GH_GrantsAccessTo and runner-group GH_AssignedTo emissions, update runner and repository panel queries, and refresh schema/docs/tests for the new path shape.

Walkthrough

The runner graph now separates repository eligibility from workflow dispatch. It models direct runner membership and enterprise inheritance with traversable edges. Policy-aware lookups, repository runner queries, schemas, descriptions, and tests were updated.

Changes

Runner access model

Layer / File(s) Summary
Relationship contracts and descriptions
descriptions/edges/*, descriptions/nodes/*, extension/schema.json, src/openhound_github/kinds/edges.py
The schema and descriptions add GH_HasRunner and GH_IsEligibleFor, make inheritance and dispatch edges traversable, and remove GH_GrantsAccessTo.
Policy-aware access data
src/openhound_github/lookup.py, src/openhound_github/resources/organization.py
Cached lookups return Actions settings, enabled repositories, branches, and inherited workflow restrictions. Access records include restricted_to_workflows.
Runner graph generation
src/openhound_github/models/runner.py
Runner models emit eligibility, filtered dispatch, creation, inheritance, and direct membership edges. Enterprise assignment and composed runner-access generation are removed.
Repository runner query paths
src/openhound_github/models/repository.py
query_runners combines repository-owned, organization-group, and enterprise-inherited runner paths with three UNION branches.
Runner access validation
tests/test_runner_models.py, tests/test_runner_resources.py
Tests validate traversability, Actions and workflow restrictions, inherited access, repository creation access, lookup results, and resource output.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 672df

The PR changes runner access modeling and query paths, but targeted coverage remains missing for enterprise workflow restrictions and propagation of non-null workflow restrictions. The change is mergeable with explicit owner awareness or follow-up for these bounded regression risks.

Comment thread descriptions/nodes/GH_EnterpriseRunner.md Outdated
Document the full repository-to-org-runner-group-to-enterprise-runner path in the enterprise runner node and GH_HasRunner edge descriptions.
Split runner group repository policy from executable runner access by introducing the non-traversable GH_IsEligibleFor edge and reserving GH_CanUseRunner for repositories and branches that can actually dispatch workflows.

Emit traversable GH_CanUseRunner edges only when Actions is enabled for the repository and the relevant organization and inherited enterprise runner groups are not restricted to selected workflows. Add GH_HasRunner and traversable GH_InheritedFrom composition support so runner-group paths continue through to the underlying runner.

Make GH_CanCreateRepositoryWithRunnerAccess traversable only when a newly created repository would immediately be usable: the repository visibility is in scope, organization Actions are enabled for all repositories, and the runner-group workflow policy is unrestricted. Update schema metadata, descriptions, lookups, collection fields, and focused tests to document and validate the new model.

Add the negative case for the enterprise creation gate.

The test name states a requirement, but the fixture only covers the allowed path. enterprise_runner_group_restricted_to_workflows_for_inherited_org_group returns False, so the creation edge is emitted. No test asserts that a restricted enterprise group suppresses CAN_CREATE_REPOSITORY_WITH_RUNNER_ACCESS. Add a companion test that returns True from that lookup and expects no creation edge.

    access = OrgRunnerGroupAccess(

Cover the populated restricted_to_workflows value.

The fixture omits restricted_to_workflows, so org_runner_group_access falls back to None through getattr. The assertion confirms only the fallback. Set the attribute on the SimpleNamespace fixture, or add a second case, so the test proves the producer forwards a real value.

🧪 Proposed change
     group = SimpleNamespace(
         id=1,
         name="Default",
         visibility="selected",
         allows_public_repositories=False,
+        restricted_to_workflows=True,
         inherited=True,
         org_login="acme",
     )
-            "restricted_to_workflows": None,
+            "restricted_to_workflows": True,

Keep a separate case with the attribute omitted if the None fallback must stay covered.

Add negative coverage for inherited runner groups whose enterprise workflow policy remains restricted, ensuring GH_CanCreateRepositoryWithRunnerAccess is not emitted in that case.

Update the runner-group resource fixture to assert restricted_to_workflows is forwarded from collected group data instead of only exercising the compatibility fallback.
