Summary

  • collect external-group mappings for normal organization teams and store external_group_id / external_group_name on GH_Team
  • use an adaptive group-first vs team-first REST strategy with expected permission and explicit-member failure handling
  • preprocess enterprise SCIM groups and emit SCIM_Group -[:SCIM_Provisioned]-> GH_Team for unique enterprise-scoped display name matches
  • add shared GitHub retry helpers and test coverage for lookup scoping, mapping behavior, and edge emission

Testing

  • uv run ruff check src/openhound_github/main.py src/openhound_github/transforms.py src/openhound_github/lookup.py src/openhound_github/models/team.py tests/test_lookup.py tests/test_team_external_groups.py
  • uv run pytest
  • verified converted output contains four expected SCIM_Provisioned edges for externally managed org teams

Summary by CodeRabbit

  • New Features

    • Added support for GitHub team-to-external identity-provider group mappings.
    • Teams now display external group identifiers and names.
    • Added SCIM-provisioned relationships for uniquely matched enterprise groups.
    • Enterprise team projections now include organization team relationships.
    • Improved GitHub rate-limit detection and retry behavior.
  • Bug Fixes

    • Prevented ambiguous or unsupported group matches from creating incorrect relationships.
    • Improved handling of missing permissions and optional data.
    • Excluded invalid enterprise-team entries from organization mappings.
  • Documentation

    • Added guidance on privileged permissions and GitHub collector configuration.

Collect GitHub external-group mappings for normal organization teams and retain the external group ID and name as evidence on GH_Team nodes. Use an adaptive group-first or team-first REST strategy to avoid unnecessary API calls, cache organization team enumeration, and handle expected permission and explicit-member failures without failing the collection.

Preprocess enterprise SCIM groups and resolve team external group names within the containing enterprise scope so GH_Team conversion can emit SCIM_Provisioned edges only for unique matches. Keep org-only collections and ambiguous names from producing speculative relationships.

Add shared GitHub retry helpers and compatibility exports used by the release tests, plus coverage for external-group collection, lookup scoping, failure handling, and SCIM edge emission.

Walkthrough

The change adds GitHub response retry classifiers and external team-group collection. It adds optional schemas, cached lookups, team properties, SCIM provisioning edges, resource wiring, relationship descriptions, documentation, and tests.

Changes

External team group integration

Layer / File(s) Summary
GitHub retry classification
src/openhound_github/github_retry.py, src/openhound_github/github_rest_client.py, src/openhound_github/helpers.py
Adds classifiers for primary limits, secondary limits, and Retry-After responses. The retry policy uses these classifiers.
External-group schemas and lookups
src/openhound_github/transforms.py, src/openhound_github/source.py, src/openhound_github/main.py, src/openhound_github/lookup.py, tests/test_lookup.py
Adds optional input tables, REST team caching, lookup mappings, and scoped lookup tests.
External-group collection resource
src/openhound_github/resources/organization.py, tests/test_team_external_groups.py, tests/test_error_resilience.py, README.md
Collects normalized mappings through group or team endpoints, handles permission failures, reuses cached teams, registers the resource, and documents required permissions.
Team properties and SCIM edges
src/openhound_github/models/team.py, src/openhound_github/models/__init__.py, descriptions/edges/GH_MemberOf.md, extension/schema.json, tests/test_team_external_groups.py
Adds external-group properties and TeamExternalGroup. Teams emit SCIM_PROVISIONED edges for unique SCIM group matches. Relationship descriptions and tests cover the behavior.

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

Merge Risk: 🟡 Moderate · up to dc0bb

The new organization team/group correlation can produce inconsistent mappings depending on which lookup strategy is used because enterprise-projected teams are not excluded consistently. Merge should wait for this bounded correctness issue to be fixed or explicitly accepted by the owner.

Poem

I’m a rabbit with mappings neat
Groups and teams now hop in step
SCIM edges bloom from names
Retry guards watch API games
Caches keep my carrots fresh happily

301-332: 🗄️ Data Integrity & Integration | 🔵 Trivial | 💤 Low value

Filter enterprise-projected teams in the group-first path for parity.

team_external_groups filters out ent: slugs before calling _team_external_groups_by_team (Line 752). The group-first path does not apply the same filter. It emits a row for every team_id returned in the group detail payload. The two paths therefore produce different row sets for the same organization.

Pass the allowed team database IDs into _team_external_groups_by_group and skip teams outside that set.

♻️ Proposed parity fix
 def _team_external_groups_by_group(
-    client: RESTClient, org_name: str, groups: list[dict[str, Any]]
+    client: RESTClient,
+    org_name: str,
+    groups: list[dict[str, Any]],
+    allowed_team_ids: set[int],
 ) -> Iterator[dict[str, Any]]:
@@
         for team in group_details.get("teams") or []:
+            if team.get("team_id") not in allowed_team_ids:
+                continue
             row = _team_external_group_row(

Then update the caller:

-                yield from _team_external_groups_by_group(client, org_name, groups)
+                yield from _team_external_groups_by_group(
+                    client, org_name, groups, {team["id"] for team in teams}
+                )

Keep the group-first external-group collection path aligned with the team-first path by filtering returned team IDs against the already-collected normal organization teams. This prevents external-group detail responses from emitting mappings for excluded enterprise-prefixed teams or other teams outside the filtered team set.

Add a regression fixture that includes an ent: team in a group detail payload and verifies that it is ignored.

Functionally sound PR. This adds a new collector permission in GitHub to get the benefit: Members: write. That's a privileged permission. I looked for documentation on required privileges. There is no documentation of required privileges in the repo itself, which seems to be the norm.

The official documentation at https://bloodhound.specterops.io/openhound/collectors/github/configure-enterprise-app and the PAT/Org documented privileges if applicable need to be updated.

In any case where a privilege exceeds the "read-only" privilege we specify for least privilege collection, the benefits of providing that permission to the collector should be clearly stated in the documentation, including which edges and attack path visibility would be gained from privileged collection.
