HCNM — Harm Containment Need Module
OOF® Origin Open Foundation®
Independent Methodological Authority
Canonical Definition
The HCNM — Harm Containment Need Module governs how the need to contain analready governed Harm is identified, qualified, prioritized, maintained,
reassessed, and transferred into actionable Containment governance.
HCNM determines whether existing Harm presents a materially relevant
possibility of further continuation, expansion, accumulation, compounding,
propagation, cascading, or creation of additional Harm such that
intervention is required to bound, interrupt, isolate, restrict, or stop
that development.
It establishes the transition:
Governed Harm Change & Propagation State + Current Harm State →
Containment Need Identification → Containment Need Qualification →
Containment Priority → Containment Objective → Governed Harm Containment
Need
Its central question is:
Does the current Harm dynamic require intervention to prevent materially
relevant additional Harm, and what specifically must Containment prevent
from continuing?
- Operational Role
HCNM is the entry point into Harm Containment governance.
Its operational role is:
to determine whether Containment is required before selecting or executing
a Containment action.
HCNM separates:
the existence of Harm
from:
the need to prevent additional Harm
A Harm may exist without currently requiring active Containment.
Conversely, a Harm may require immediate Containment even while its
complete downstream consequences remain uncertain.
- Position Within HCOS
The HCOS governance flow is:
Containment Need → Containment Action → Containment Boundary → Containment
Persistence → Containment Verification
HCNM governs the first stage:
Containment Need
It primarily receives:Governed Harm State
and:Governed Harm Change & Propagation State
It produces:Governed Harm Containment Need
for subsequent Containment Action governance.- Governed Object
The primary governed object is:
Need to Prevent Further Harm Development
HCNM does not determine whether Harm exists.That has already been governed through earlier HAGA™ stages.
It asks whether the established Harm can materially continue developing in
a manner that requires Containment.
Therefore:
Existing Harm ≠ Automatic Containment Need
and:
Containment Need ≠ New Harm Determination
- Foundational Principle
The foundational rule is:
Containment Need is determined by the material possibility of further Harm
development, not merely by the severity of Harm already present.
A severe Harm that is no longer capable of further expansion may require
Mitigation and Recovery without requiring the same active Containment
response.
A currently limited Harm with rapid Propagation potential may require
immediate Containment.
Therefore:
Current Harm Severity ≠ Containment Need by Default
- Containment Need Identification
Containment Need should be evaluated where existing Harm may materially:
continue
increase
accumulate
compound
propagate
cascade
reach additional affected scope
or:
produce further Harm
The relevant question is prospective but grounded in current governed Harm
reality:
What additional Harm development remains materially possible if no
Containment occurs?
- Containment Need Sources
A Containment Need may arise from one or several governed Harm dynamics.
These include:
Active Harm continuation
Accumulation
Compounding
Propagation
Cascading
Boundary expansion
new exposure creationor:
other materially relevant continuation
HCNM must preserve which Harm dynamic creates the Need.
A generic statement that “Containment is required” is insufficient where
the actual target of Containment is unknown.
- Harm Dynamics as the Basis
HCNM should use the best available governed representation of Harm
dynamics.
Conceptually:
Harm State + Harm Trajectory + Propagation Pathways + Cascade Development
+ Relevant Uncertainty → Containment Need
The Need must therefore remain linked to actual Harm conditions rather
than only to:
policy preference
organizational concern
public perception
administrative status
or:
completion of an internal process
- Active Harm ≠ Automatic Containment Need
An Active Harm may already be bounded.
For example, an existing physical injury may remain Active but no longer
be capable of spreading or increasing through the original mechanism.
The Harm may require:
Mitigation
Recovery
and:Monitoring
without an active Need to contain further expansion.Therefore:
Active Harm ≠ Active Containment Need by Default
- Limited Harm May Create High Containment Need
The opposite condition is also possible.
Current Harm may be limited while its propagation potential is
substantial.
For example:
Limited Harm + Rapid Propagation Potential → High Containment Need
HCNM must therefore avoid deriving Containment Need solely from present
Harm magnitude.
Canonical principle:
Small Current Harm ≠ Small Containment Need
- Accumulation-Based Containment Need
Where repeated or continuing contributions are increasing Harm:
Contribution₁ + Contribution₂ + Contribution₃ + …
HCNM may establish a Need to interrupt further contribution.
The Containment target becomes:
additional accumulation
rather than:
the accumulated Harm already present
Therefore:
Containment of Accumulation Targets Further Contribution, Not Historical
Harm
- Compounding-Based Containment Need
Where interacting conditions materially amplify existing Harm, the Need
may concern:
preventing further interaction
separating conditions
interrupting a dependency
or:
preventing additional amplification
The Need should identify the materially relevant compounding relationship
without prescribing the eventual Containment action.
- Propagation-Based Containment Need
Where Harm is spreading, HCNM should identify whether further:
subjects
objects
systems
organizations
locations
domains
infrastructure
environments
or:
populations
may become materially affected.
The Containment Need must remain connected to the actual or sufficiently
governed propagation pathway.
- Cascade-Based Containment Need
Where Harm is generating further Harm:
Harm₁ → Harm₂ → Harm₃
Containment Need may exist at several points.
HCNM may identify:
upstream Need
pathway Need
branch-specific Need
or:
downstream Need
without deciding which Containment action will ultimately be selected.
- Continuation After Mechanism Termination
A Containment Need may remain after the originating mechanism has stopped.
For example:
System Stopped → Harm Continues Propagating
or:
Source Removed → Environmental Harm Continues Moving
Therefore:
Mechanism Termination ≠ Containment Need Termination
HCNM follows Harm dynamics rather than mechanism status.
- Containment Need Under Uncertainty
Containment Need does not require complete knowledge of every future Harm
consequence.
Where credible governed information indicates a materially relevant
possibility of further Harm, uncertainty must be represented rather than
converted into either:
false certainty
or:
false absence of Need
Possible states may include:
Containment Need Established
Containment Need Partially Established
Potential Containment Need
Containment Need Uncertain
No Active Containment Need Established- Urgency
Containment Need may carry different urgency.
Relevant factors may include:
Propagation velocity
rate of accumulationrate of compounding
cascade development
time to additional exposure
irreversibility
difficulty of later Containment
and:
material expansion potential
Urgency concerns:
how quickly Containment governance must act
It does not automatically represent:
Harm severity
or:liability
- Containment Priority
Where several Harm dynamics require Containment simultaneously, HCNM may
establish relative operational priority.
Priority may consider:
immediacy
expansion potential
Propagation velocity
cascade potentialadditional affected scope
irreversibility
Containment window
and:dependency between Containment Needs
Priority must be traceable to the governed Harm dynamics.
Canonical distinction:
Containment Priority ≠ Harm Value Ranking
- Containment Window
Some Harm dynamics may only remain containable within a limited period.
HCNM may identify a:
Containment Window
representing the period within which intervention can materially preventfurther Harm development.
The window may be:
Immediate
Short
Extended
Conditional
or:Uncertain
A closing Containment Window may increase urgency even where current Harmremains limited.
- Containment Objective Formation
HCNM must convert the identified Need into a sufficiently clear
Containment Objective.
Examples include:
prevent further exposure
stop additional accumulation
interrupt a compounding interaction
stop propagation beyond Scope A
prevent Harm₂ from generating Harm₃
or:
prevent additional systems from becoming affected
The objective describes:
what further Harm development must be prevented
It does not prescribe:
how the intervention must be performed
That belongs to subsequent Containment Action governance.
- Objective Specificity
A Containment Objective must be specific enough to support later
verification.
For example:
“Contain the situation”
is methodologically weak.
Whereas:
“Prevent the governed Harm from propagating from System A into currently
unaffected dependent systems”
creates a verifiable objective.
Canonical principle:
A Containment Need that cannot identify what must stop cannot support
reliable Containment Verification.
- Multiple Containment Needs
One Harm may produce several simultaneous Containment Needs.
For example:
stop additional exposure
interrupt current propagation
and:
prevent cascade formation
These Needs should not be artificially collapsed where they require
materially different governance.
HCNM may therefore produce a:
Containment Need Set
linked to one governed Harm.- Distributed Containment Need
In distributed environments, the Need may span:
multiple agents
systems
providers
organizations
locations
or:
infrastructure
No single component may contain the complete Harm dynamic.
Canonical principle:
Distributed Harm Dynamics Require Distributed Containment Need
Representation.
A local Need must not be mistaken for the complete Containment Need.
- Composite Containment Need
Composite Harm may require Containment even where no single component
independently creates sufficient Need.
Conceptually:
Limited Dynamic₁ + Limited Dynamic₂ + Limited Dynamic₃ → Material
Composite Containment Need
Therefore:
No Single Dominant Harm Pathway ≠ No Containment Need
The appropriate Harm-object level must govern the conclusion.
- Collective Containment Need
Collective Harm may require Containment even where no single affected
individual demonstrates the complete Harm dynamic.
HCNM must support Need determination at:
group
population
system
infrastructure
environment
or:
societal
level where appropriate.
Therefore:
No Single Dominant Harmed Subject ≠ No Collective Containment Need
- Containment Need Reassessment
Containment Need is not permanently fixed.
It must be reassessed where material changes occur in:
Harm State
Accumulation
Compounding
Propagation
Cascading
Boundary
affected scopeintervention capability
or:
operational reality
A Need may:
emerge
increase
decrease
change target
become uncertain
or:
cease
- Containment Need Persistence
A Need remains active while the material possibility of the targeted
further Harm development remains sufficiently present.
Therefore:
Containment Action Initiated ≠ Containment Need Ended
and:
Temporary Harm Stability ≠ Containment Need Ended by Default
The Need should not close merely because intervention has begun.
- Containment Need Closure
A Containment Need may cease when:
the targeted Harm dynamic is no longer materially capable of continuing
or:
verified Containment has removed the relevant further-development pathway
subject to appropriate monitoring and uncertainty.
However:
Containment Need Closed ≠ Harm Resolved
The existing Harm may continue through:
Mitigation
Recovery
Residual Harm
Resolution
and:Finality
- Prediction and Simulation Boundary
PGA™ may identify possible future Harm trajectories.
SIMULOS® may model potential spread or Containment scenarios.
These may support HCNM.
But:
Predicted Harm Expansion ≠ Actual Harm Expansion
and:
Simulated Containment Need ≠ Established Containment Need
HCNM must anchor its output in the governed operational Harm context while
preserving uncertainty about future development.
- Accountability and Liability Boundary
Containment Need is independent of whether responsibility or liability has
been established.
Urgent Harm Containment may be necessary before those questions are
resolved.
Therefore:
Unresolved Accountability ≠ No Containment Need
Unresolved Liability ≠ No Containment Need
HCNM governs prevention of additional Harm, not assignment of
responsibility.
- Minimum Implementation Framework
A minimum HCNM implementation requires eight capabilities.
- Harm Dynamic Intake
Receive and maintain the relevant Governed Harm State and Harm Change &
Propagation information.
- Further-Harm Potential Assessment
Determine whether Harm may materially continue, increase, accumulate,
compound, propagate, cascade, or create additional Harm.
- Containment Need Qualification
Distinguish Established, Partial, Potential, Uncertain, and No Active
Containment Need conditions.
- Urgency & Containment Window Governance
Represent how quickly intervention may be required and whether the
opportunity for effective Containment is time-limited.
- Containment Priority Governance
Prioritize multiple Containment Needs using traceable Harm-dynamic factors
without converting priority into Harm value ranking.
- Containment Objective Formation
Define what further Harm development must be prevented without prematurely
prescribing the intervention mechanism.
- Reassessment & Need Persistence
Maintain, update, escalate, reduce, or close Containment Need as Harm
dynamics and operational conditions change.
- Governed Output
Produce a traceable Governed Harm Containment Need suitable for
Containment Action governance. 32. Use Case 1 — Limited Harm With Rapid
Propagation Potential
A digital Harm currently affects only one operational environment.
HCPS establishes that an active pathway could rapidly propagate the Harm
into numerous dependent systems.
The current Harm remains limited, but the opportunity to interrupt the
pathway is short.
HCNM therefore establishes:
Limited Current Harm + High Propagation Potential + Short Containment
Window → High-Urgency Containment Need
It does not wait for widespread Harm before recognizing the Need.
The governing principle is:
Containment Need is determined by the material possibility of additional
Harm, not only by the amount of Harm already present.
- Use Case 2 — Source Stopped but Cascade Continues
An operational failure produces Harm₁.
The original process is stopped.
However, Harm₁ has already created Harm₂, and Harm₂ remains capable of
producing Harm₃.
HCNM does not conclude:
Source Stopped → No Containment Need
Instead it evaluates the active downstream Harm dynamics and establishes a
Containment Need directed at preventing further cascade development.
The governing principle is:
Mechanism termination does not terminate Containment Need while Harm
remains capable of producing further Harm.
- Governance Requirements
HCNM requires that:
- Containment Need be derived from an already governed Harm
- current Harm severity not be used as the sole proxy for
Containment
Need; - further-Harm potential remain distinguishable from existing Harm
magnitude; - the Harm dynamic creating the Need be explicitly identified;
- Accumulation-, Compounding-, Propagation-, and Cascade-based Needs
remain distinguishable; - mechanism termination not automatically
terminate Containment Need; - uncertainty not be converted into false
absence of Need; - urgency remain distinguishable from Harm severity; -
priority remain traceable to Harm dynamics; - time-limited Containment
opportunities remain representable; - every Containment Need produce a
sufficiently specific Containment Objective; - multiple Needs remain
separately governable where necessary; - distributed, composite, and
collective Containment Needs remain representable; - Containment Need be
reassessed when Harm dynamics materially change; - action initiation not
automatically close the Need; - Need closure remain separate from Harm
Resolution or Finality; - Prediction and Simulation support but do not
replace actual Need governance; - accountability and liability
determination not be prerequisites for necessary Harm Containment.
- Governance Logic
HCNM applies the following logic:
Does a governed Harm exist?
If no:
→ HCNM does not establish formal Harm Containment Need.
If yes:
→ assess the current Harm dynamics.
Can the Harm materially continue, increase, accumulate, compound,
propagate, cascade, expand scope, or generate additional Harm?
If no:
→ No Active Containment Need may be established, subject to Monitoring and
uncertainty.
If yes or materially possible:
→ identify the specific dynamic requiring Containment.
Then determine:
What further Harm development must be prevented?
→ establish the Containment Objective.
How quickly may that development occur?
→ establish urgency.
Is effective Containment time-limited?
→ establish the Containment Window.
Are multiple Containment Needs present?
→ preserve and prioritize them where required.
Is the Need distributed, composite, or collective?
→ evaluate it at the appropriate Harm-object level.
Is material uncertainty present?
→ preserve the uncertainty state.
The output becomes:
Governed Harm Containment Need → Containment Action Governance
At every stage:
Existing Harm ≠ Automatic Containment Need
Current Severity ≠ Containment Need
Small Current Harm ≠ Small Containment Need
Mechanism Termination ≠ Containment Need Termination
Action Initiated ≠ Need Ended
Need Closed ≠ Harm Resolved
- Governance Outputs

- Canonical Boundary
The HCNM — Harm Containment Need Module governs whether an already
governed Harm presents a materially relevant need for intervention to
prevent further continuation, expansion, accumulation, compounding,
propagation, cascading, additional exposure, or creation of downstream
Harm. It governs the identification, qualification, urgency, priority,
Containment Window, objective formation, persistence, reassessment,
uncertainty, and closure of that Need. HCNM does not determine whether
Harm originally exists, perform Recognition or Determination,
independently redefine the Governed Harm Boundary, select or execute the
Containment Action, establish the Containment Boundary, verify Containment
effectiveness, perform Mitigation, govern Recovery, Residual Harm,
Resolution or Finality, determine general causation, or assign
accountability, responsibility, or liability.
- Canonical Closing Statement
Containment should not begin only after Harm has already reached its
largest observable form.
A limited Harm may create an urgent Containment Need when its pathway
remains open, while a severe but fully bounded Harm may require Mitigation
rather than further Containment.
HCNM governs that distinction by asking not only how much Harm exists now,
but what additional Harm remains materially possible if nothing interrupts
its development.
Containment Need begins where existing Harm still has somewhere further to
go.
