Two Layers, One Purpose
Canonical Layer
The authoritative business state. Reflects source systems and the unified context Spine Fabric assembles from them. This is the durable memory of the business: entities, events, evidence, decisions, and receipts. AI does not write here directly.
Operational Layer
The agentic workspace where AI drafts, proposes, simulates, and executes. Mistakes are recoverable. Proposals can be rejected. Nothing here is authoritative until it passes through governance into the canonical layer.
What Separates Them
Governance is the bridge and the gate. It enforces authorization, scope, approvals, and receipts for every operation that moves from operational to canonical. This is not a configuration setting. It is a structural property of how Spine Fabric and SpineWorkspace are built.The Governed Path From Operational to Canonical
Every meaningful action follows the same path. This path keeps the canonical layer clean while giving AI and humans maximum flexibility in the operational layer.1
Propose
The agent or human drafts an action in the operational layer: a message, a record update, a workflow. It is assembled from shared context but has not yet touched the canonical state.
2
Simulate
Where possible, the effect is previewed. The agent shows what would change, which systems would be touched, and what the outcome would look like. The human reviews with full transparency.
3
Approve
Governance applies authorization checks, scope validation, and approval rules. The human with authority confirms. The capability is unlocked.
4
Write-back
The governed capability executes against the relevant source systems. The canonical layer updates to reflect the new truth. The change is permanent and auditable.
5
Receipt
A receipt is generated and attached to the shared thread. The business memory now includes what happened, who approved it, and why. The next agent or human starts from this updated state.
