Define when physical proof is required.
Institutions specify the people, objects, actions, contexts and assurance levels that should invoke Presence.
Presence / 03 · Institutional control
Presence
Home.
The control plane for governing how physical verification becomes accountable institutional action.
01 / FROM SIGNAL TO CONTROL
Verification becomes useful only when
policy knows what to do with it.
The institutional home
for physical trust.
Presence Home coordinates the control surfaces around physical verification without becoming another general-purpose identity or system-of-record silo.
Govern trust relationships over time.
Enrollment, review, exception, reassociation and retirement become explicit institutional processes.
Record the minimum result needed.
Verification events remain bounded to their purpose while supporting accountable review, escalation and audit.
03 / THE DECISION PATHOne control language
One control language
from reality to action.
Presence Home gives institutions a consistent way to request, interpret and govern physical verification across different people, objects and operating environments.

Not a dashboard.
An operating boundary.
The interface exists to make policy and responsibility legible. Public product views are intentionally limited while the environment remains invite-only.
Trust relationships
Which person or object is expected, which institution owns the relationship and what status applies.
Verification policy
When Presence is required, which result is sufficient and which exception path is allowed.
Operational evidence
The minimum event information required for accountability without exposing protected physical data.
Controlled integration
Where a result may go and which downstream system remains responsible for action.
One environment.
Different systems of action.
Presence Home is designed to sit beside the infrastructure an institution already relies on and strengthen the physical trust boundary between them.
Physical presence as a policy condition.
Request a Presence Key result before selected privileged access, recovery, administrative or facility-control events.
Authenticity inside custody decisions.
Use a Presence Layer result to inform receipt, hold, release, installation or transfer inside existing operational systems.
Authority before exceptional value moves.
Connect physical human participation to treasury, mandate, settlement or recovery policy at high-consequence thresholds.
Explicit human authority before execution.
Require a bounded physical authorization event before an intelligent system executes selected external actions.
06 / SYSTEM BOUNDARIESCoordinate trust.
Coordinate trust.
Preserve ownership.
Presence Home does not decide business, legal, mission or safety policy on behalf of the institution. It makes the physical verification boundary available to the systems and people who do.
PRESENCE HOME GOVERNS
Trust relationships, verification requests, bounded results, lifecycle states, evidence and integration paths.
EXISTING SYSTEMS RETAIN
Identity records, transaction authority, operational state, mission command, safety logic and final action.
DEPLOYMENT REQUIRES
A defined threat model, policy owner, exception path, data boundary, integration contract and review process.
Begin with one
consequential workflow.
Presence Home is introduced through a bounded institutional deployment—not a broad platform rollout without a defined control objective.
Identify the claim.
Find the digital claim that can move value, grant access or trigger consequence.
Set the boundary.
Specify the expected person or object and the physical condition that matters.
Integrate the result.
Define the receiving system, data contract and policy owner.
Test failure modes.
Evaluate exceptions, ambiguity, denial, loss, recovery and adversarial use.
Operate deliberately.
Monitor policy, lifecycle, evidence and accountability over time.
Invite-only by design.
Integration-led by default.
Presence Home is being developed with selected institutions whose workflows can define the platform’s first operating standards.
Start where physical proof
must become accountable action.
4SI works with selected institutions to map policy, integration, evidence, exceptions and governance before deployment.
