#3529 derives a domain-level BadSuccessor relationship from CreateDMSA without distinguishing domain controller patch state. That overstates reachability on fully patched domains, where the analysis must also establish write access to both victim attributes. The standard AD ingest path also needs to accept the collector's typed dMSA output.
Solution
I retained #3529's dMSA schema and post-processing work and made the derivation patch-aware. The analysis now uses registry-backed domain controller build and revision data, emitting the domain relationship only when a collected Windows Server 2025 controller predates build 26100.4946. Patched or unknown environments use the conservative target-specific model: the same CreateDMSA principal must have GenericAll, GenericWrite, or both attribute-specific write relationships over the victim.
I added typed dmsas ingestion to the standard AD pipeline. It creates DMSA nodes and graphs access-control, containment, and predecessor relationships before post-processing evaluates DMSAPrecededBy. I also added schema support for the build evidence and attribute-specific relationships, grouped the four dMSA relationships under Delegated Managed Service Accounts, and moved exported schema coverage to package ad_test.
Graph-side implementation for #2424; the issue remains open until the collector companions are merged.

The AD graph schema and ingestion pipeline add DMSA data and Windows build properties. Post-processing derives BadSuccessor and OuroborosSelfEnroll relationships. The UI schema and edge filter expose the new node, properties, and relationships.
The AD schemas register DMSA and its relationships, and add Windows build properties to graph-schema definitions and lists. The SQL migration registers DMSA metadata and relationship traversal settings. Tests check DMSA display metadata and schema registration.
Collect Windows build metadata and ingest DMSA data packages/go/ein/incoming_models.go, packages/go/ein/ad.go, packages/go/ein/ad_test.go, packages/go/chow/ingest/ingest.go, packages/go/chow/ingest/ingest_test.go, cmd/api/src/services/graphify/convertors.go, cmd/api/src/services/graphify/convertors_internal_test.go, cmd/api/src/services/graphify/ingest.go
DC registry input models and parsing add build number, revision, and collection status. Ingest accepts DMSA records, and graphify converts them into nodes and relationships. Tests cover registry values, predecessor relationships, and DMSA conversion.
Post-processing generates BadSuccessor edges based on build data and target rights, and OuroborosSelfEnroll edges from Owns or GenericAll relationships to DMSA nodes. The post-processing pipeline invokes both processors. Tests cover build thresholds, target rights, deduplication, and generated edges.
Expose DMSA kinds in the UI packages/javascript/bh-shared-ui/src/graphSchema.ts, packages/javascript/bh-shared-ui/src/views/Explore/ExploreSearch/EdgeFilter/edgeCategories.tsx
The shared UI schema adds DMSA kinds, relationship and property labels, and pathfinding relationships. The edge filter adds a Delegated Managed Service Accounts category.

Merge Risk: Moderate · previous review 3f5e9
If a domain controller reports a build number that cannot be parsed, an earlier build value can remain on its node. That can produce an incorrect BadSuccessor relationship in the graph. Only the parser's collected flag needs fixing, and the matching test expectation needs updating, before merging.

Major · Add dMSA collection and graphification to the standard AD ingestion path. · dmsa.go:320-323
packages/go/analysis/ad/dmsa.go:320-323 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Add dMSA collection and graphification to the standard AD ingestion path.
PostOuroborosSelfEnroll can emit an edge only when an Owns or GenericAll relationship ends at a DMSA node. The standard AD models and converters define no dMSA object or msDS-ManagedAccountPrecededByLink field, so standard AD ingestion creates no such endpoint or DMSAPrecededBy edge. ACL parsing of CreateDMSA or WriteSuperseded* rights does not create either object nodes or structural predecessor edges. As a result, this post-processing query produces no OuroborosSelfEnroll edges for normal AD collection.
Add the dMSA object class and msDS-ManagedAccountPrecededByLink to the AD collection payload, then add the typed model, decoder/converter, and structural DMSAPrecededBy relationship. The generic OpenGraph path can accept arbitrary node and edge kinds, but it does not supply these objects from standard AD collection.

Major · Mark the build as collected only after the build number parses. · ad.go:1611-1618
packages/go/ein/ad.go:1611-1618 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
Mark the build as collected only after the build number parses.
When parsing fails, the current code still sets WindowsBuildCollected=true and stores the revision. Batch.UpdateNodeBy merges properties, so an omitted build number can remain on an existing node. fetchDomainControllerBuilds can then combine that stale build number with the new revision and emit an incorrect domain-level BadSuccessor edge.
Also update TestParseDCRegistryData_InvalidWindowsBuildNumber to expect WindowsBuildCollected=false.

I addressed the latest data-integrity review in 8f8c618. An invalid CurrentBuildNumber now leaves WindowsBuildCollected false and writes neither build nor revision, preventing a stale stored build from being paired with a new revision. The regression failed before the change and now passes; the related ingest, graphify, ein, and AD analysis packages plus go vet, license, and repository analysis checks pass.

Merged current main in 5baad52 and regenerated the combined graph schema to resolve the conflict. The dMSA processors now follow the updated sink lifecycle: failed generations retain existing relationships, and writer/pruning errors propagate to the caller. The caller-contract regression fails before the lifecycle update and passes after it.
The focused analysis, ingest, payload, graphify and schema tests, plus the corresponding go vet checks, pass on the published candidate in the Ubuntu lab. Database integration tests were not run. Please approve CI for the updated head and review the integration.
