01TARGET
Define the target
Intent becomes a verifiable, versioned specification that is frozen before execution.

Build with agents.Deliver with evidence.
Sawbill is the open-source control plane for the agentic construction of complex systems. It turns intent into a verifiable contract, observes the actual result, and refuses acceptance when evidence falls short.

Speed matters. Evidence decides.
/ THE PRODUCT
From brief to accepted deliverable.
Sawbill maintains a verifiable thread between what you intended, what agents did, and what you can actually accept.
02EXECUTION
Orchestrate the work
Work is sliced, ordered, and assigned to the right agents in a distinct execution DAG.
03ACTUAL
Observe the actual
Sawbill reconstructs what was really produced and measures every divergence from the target.
04ACCEPT / BLOCK
Decide on evidence
A result is accepted only when the required evidence is bound to the exact contract.
/ WHY SAWBILL
An agent can assert. Sawbill asks to verify.
A green test, a signature, or a “completed” status is not enough to prove that a system matches its intent.
History is never rewritten
Every attempt, decision, and piece of evidence stays traceable. A retry creates a new attempt.
Actual stays distinct from target
The target graph, actual graph, and divergence report are separate, versioned artifacts.
Uncertainty remains visible
Unknown coverage stays UNKNOWN. It is never silently converted into compliance.
/ BUILT TO COMPOSE
Why not OPA/Kyverno + in-toto + CI gates?
- 01
OPA and Kyverno make policy decisions at defined enforcement points.
- 02
in-toto records software supply-chain steps; CI gates approve a pipeline state.
- 03
Sawbill binds target, actual, policy, evidence, and acceptance across agent attempts — using those tools as inputs and enforcement points, not replacing them.
/ WHITE PAPERS
Go deeper into governed agentic construction.
Four concise papers explore the control boundaries that turn agent activity into attributable, verifiable, and auditable work.

/ DATA RESIDENCY
Governed work, in the region you choose.
Sawbill SaaS is being designed around regional cells in Canada, the United States, and Europe. Data location becomes a first-class deployment choice for Quebec and Canadian public-sector teams.
Available regions and contractual residency commitments will be confirmed for each deployment.Discuss Canadian residencyREGION / 01Canada

/ TWO EDITIONS, ONE MEANING
Open locally. Operated at scale.
OpenCore
A local, self-hostable composition for one owner, one repository, and autonomous governance — including offline operation.
- Local Studio and CLI
- Open contracts and formats
- Portable export and verification
Sawbill SaaS
The same governance, extended for teams, multi-repository portfolios, distributed workers, and regional operations.
- Multi-user collaboration
- Multi-model orchestration
- Canada, United States, and Europe cells
The same evidence keeps the same meaning in both editions.
