# HR Spine Fabric: Context Assembly and Projection

> See how Spine Fabric ingests HR source systems, assembles entity context, and projects the Human Resources domain into the workbench.

Spine Fabric is the layer that makes the HR domain possible. It ingests data from Workday, BambooHR, Greenhouse, Lever, DocuSign, Slack, and Gmail, then unifies entities, events, and evidence into a single context graph. The HR domain is a read-time projection of that graph, not a separate database.

## Sources and Scopes

| Source System | Scope                                      | Entities Ingested                      |
| ------------- | ------------------------------------------ | -------------------------------------- |
| Workday       | Employee data, org structure, compensation | Employee, JobRequisition, Compensation |
| BambooHR      | People records, time off, onboarding       | Employee, Onboarding Task, Policy      |
| Greenhouse    | Recruiting pipeline, interviews, offers    | Candidate, Interview, Offer            |
| Lever         | Recruiting pipeline and feedback           | Candidate, Interview                   |
| DocuSign      | Signatures for offers and policies         | Offer, Policy Attestation              |
| Slack         | Notifications and channel activity         | Event Log, Mention                     |
| Gmail         | Scheduling and candidate communication     | Interview, Candidate Thread            |

## Event Sequence

1. **Intake:** connectors poll APIs and webhooks for changes in each source.
2. **Normalize:** events are mapped to a common schema and deduplicated.
3. **Entity Link:** candidates, employees, and offers are matched across sources.
4. **Context Assembly:** related entities, events, and evidence are gathered into a context bundle.
5. **Projection:** the bundle is rendered into a domain view in the workbench.

<Tip>
  You can inspect the context bundle for any candidate or employee by opening the detail panel and selecting "View Context."
