SCIM graph conversion drops resource metadata and user role/group details, and user-to-external-identity correlation fails when the same GitHub scope is collected with differently cased slugs.
This change preserves user/group resource URLs and timestamps, maps user profile_url from profileUrl, and retains complete user roles and groups as JSON properties. It adds active alongside the existing enabled, a returned-member count on groups, and the SCIM base URL and scope type on SCIM organizations. Existing property names and GitHub environment IDs are retained.
User-side membership edges supplement group member lists without duplicating their evidence. User membership and provisioning paths require an explicitly active user; inactive and unknown-state records retain their nodes, metadata, and containment. External identity correlation now uses exact, case-sensitive GUID and GitHub scope IDs, with unambiguous provider-based scope resolution for older slug-only records.
Validation: 93 focused tests passed across SCIM models/resources, external identity collection, preprocessing/lookups, enterprise resources, and team mappings. Ruff and git diff --check passed. Local collected graph output was also inspected for metadata, containment, membership, and provisioning endpoints.
Existing inactive-user provisioning edges already ingested into BloodHound may need separate cleanup; omitting them from subsequent output does not itself remove them. External provisioning-tenant discovery and provisioning-account modeling are deferred.
Summary by CodeRabbit
New Features
SCIM records now include richer profile, status, group, and organization details, including the SCIM service URL.
Active users receive membership links when supported by the available SCIM data, with duplicate memberships avoided.
External identities are associated with their provider’s scope using exact identifiers; unambiguous legacy scopes can be resolved automatically.
Bug Fixes
Missing group-member data no longer creates misleading membership links.
Ambiguous external identity matches are left unresolved.
SCIM service URLs now preserve configured API hosts and use GitHub’s default when no host is provided.
No actionable comments were generated in the recent review.
Walkthrough
The pull request adds environment node IDs to external identity records and resolves missing scope IDs. It builds SCIM base URLs from configured REST API endpoints and expands SCIM graph metadata, serialization, and membership handling.
External identity records now include environment node IDs. A transform resolves missing IDs from a unique, case-insensitive SAML or OIDC provider slug. GUID lookup filters by exact environment node ID and returns an ID only when one distinct match exists.
SCIM organization records include base URLs derived from the configured REST API endpoint. Dedicated property models define organization, user, and group metadata. Tests cover URL normalization and SCIM serialization.
SCIM graph serialization and memberships src/openhound_github/lookup.py, src/openhound_github/models/scim_user.py, tests/test_scim_models.py
User and group nodes serialize SCIM metadata, roles, groups, and member counts. User membership and provisioning edges are emitted only when active is True. Membership handling deduplicates evidence and treats an omitted group member list as empty.

Merge Risk: Minimal · up to 77ed0
The change preserves SCIM metadata and makes external-identity correlation use exact scope IDs. No concrete merge-blocking risk was identified in the supplied evidence. Inactive-user provisioning edges that were already ingested may still need separate cleanup, as the PR description notes.
Security architecture risk: Low · up to 77ed0
The change strengthens identity scoping and restricts user-derived access paths to explicitly active users. No introduced security vulnerability was established. Remaining uncertainty concerns legacy-data ownership resolution and how downstream graph refreshes handle previously stored relationships.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
observed — The changed outputs affect collected organization and enterprise identity ownership, traversable SCIM relationships, and identity metadata available to graph consumers. The inspected SCIM relationship code emits graph edges rather than performing provisioning writes against GitHub.
Trust Boundaries and Controls
observed — The new SCIM base URL is descriptive metadata derived from the configured client. Enterprise SCIM continues using ctx.client rather than the supplemental SSO client; organization SCIM continues using the configured organization client and existing relative Users endpoint.
observed — Correlation parameters are bound into SQL, exact GUID and scope-ID matching is retained, and multiple distinct identity matches produce no provisioning target. User-side duplicate membership suppression is keyed by scope, group, and user.
Resilience and Maintainability Implications
inferred — Legacy ownership resolution establishes uniqueness only within provider rows present in the lookup database. Provider collection can skip failed scopes, and the resolver has no completeness check. This leaves incomplete legacy datasets insufficiently characterized; fresh identities carrying explicit scope IDs bypass that inference, and no resulting cross-scope attack path was established.
Hardening Proposals
proposed — If incomplete or mixed legacy datasets are supported, validate collection completeness and scope provenance before backfilling ownership, or retain unresolved ownership explicitly. This is a hardening proposal, not a verified introduced vulnerability.

Reuse the normalized base-URL helper for the enterprise SCIM URL.
This code calls .rstrip('/') directly on getattr(ctx.client, 'base_url', DEFAULT_GITHUB_REST_API_URL).
If base_url is None, the transformer raises AttributeError after the SCIM probe succeeds.
If base_url is an empty string, the result is a relative "/scim/v2/enterprises/...".
The organization path avoids both cases. _rest_api_url in organization.py converts the value to str, strips whitespace, and falls back to the default URL. The two code paths now diverge.
Move that helper to a shared module and call it from both transformers.
