Purpose and description
Enable an AI agent to identify and assess nuclear warfare, distinguish actual use from threats and preparations, and support evidence-based humanitarian and risk-reduction decisions.
Nuclear warfare is armed conflict involving the use of nuclear weapons, whose explosive energy comes from nuclear fission, fusion, or both, against military or civilian targets.
It can be Classify an event under explicit definitions and document reasons for inclusion, exclusion, or uncertainty.; Compare attributed accounts of nuclear use, responsibility, and authorization without collapsing disagreement.; Construct a sourced chronology separating observed actions, public statements, and inferred escalation.; Compare humanitarian consequence assessments using compatible populations, time horizons, and assumptions.; Identify gaps in civilian protection and humanitarian response information for qualified responders.; Track cessation claims, supporting evidence, and unresolved risks of renewed nuclear use..
Distinguishing features
An instance requires evidence of nuclear-weapon use connected to armed conflict; possession, alerting, exercises, and threats alone do not establish an instance.
A radiological release alone is insufficient: distinguish a nuclear explosive weapon from a reactor accident, a conventional attack on nuclear infrastructure, or a radiological dispersal device.
A nuclear detonation must be situated in context: a weapons test is not automatically an act of nuclear warfare.
Record whether the classification includes a single unilateral use or requires an exchange; do not silently equate nuclear warfare with mutual strategic attack.
Separate an observed conflict episode from a hypothetical scenario, doctrinal concept, or simulation.
Scope
+ Classification of alleged, confirmed, and hypothetical nuclear-weapon use in armed conflict
+ Participants, attribution, decision authority, and uncertainty about authorization
+ Relationships among nuclear use, conventional hostilities, deterrence, and escalation
+ Immediate and cascading humanitarian, environmental, and societal consequences
+ Civilian protection, humanitarian response constraints, cessation, and recurrence prevention
- Nuclear-weapon design, manufacture, acquisition, and employment instructions
- Detailed targeting, strike planning, or optimization of military effects
- Civil nuclear energy operations and reactor accidents considered independently
- Radiological dispersal attacks that do not involve a nuclear explosive weapon
- General warfare, diplomacy, and arms-control institutions beyond their nuclear-conflict relationships
Characteristics
- Referent type
- observed episode | alleged episode | hypothetical scenario | doctrinal concept Prevents scenario assumptions and doctrinal language from being reported as observed events.
- Nuclear-use evidence status
- unverified allegation | supported assessment | independently corroborated | disputed | refuted Makes classification depend on traceable evidence and exposes unresolved disagreement.
- Definition applied
- Attributed definition linked to its author, date, inclusion criteria, and exclusions Allows classifications to differ transparently when sources use different boundaries.
- Episode configuration
- single use | repeated unilateral use | reciprocal use | disputed | unknown Describes the observed pattern without assuming reciprocal attack or inevitable expansion.
- Conflict relationship
- Links to associated armed conflict, preceding hostilities, and subsequent episodes Establishes the context needed to distinguish wartime use from other nuclear events.
- Attribution and authorization assessment
- Separately attributed assessments of responsible actor and authorization, each with evidence and uncertainty Prevents identification of an apparent user from being treated as proof of who ordered the event.
- Episode timing
- Timestamp or interval with time zone, precision, and uncertainty Supports reconstruction of sequences without imposing false temporal precision.
- Humanitarian impact estimate
- People killed, injured, displaced, or deprived of essential services, each with time horizon, method, and uncertainty interval Supports response assessment while preventing incompatible estimates from being combined.
- Consequence assessment basis
- direct observation | retrospective reconstruction | model projection | mixed | unknown Separates measured consequences from projections dependent on scenario assumptions.
- Cessation status
- use ongoing | reported pause | declared cessation | corroborated cessation within stated coverage | recurrence | unknown Distinguishes claims of termination from evidence that further use has stopped.

Nuclear warfare boundaries Establishes which sense of nuclear warfare is being modeled and what evidence would make an event an instance.
The registry has no definition, and different treatments may include different forms and scales of nuclear use.
Definitions and instances
Records attributed definitions and their application to actual or hypothetical episodes.
Explicit inclusion rule
Record whether a definition includes single, unilateral, demonstrative, or reciprocal wartime use, together with the source responsible for that definition.
- What does the cited source require for an event to count as nuclear warfare? definition
- Would a single wartime nuclear detonation qualify under this definition, and which borderline cases remain disputed? boundary
Adjacent nuclear events
Separates nuclear warfare from tests, threats, accidents, and non-explosive radiological events.
Event mechanism and context
Assess evidence for nuclear-weapon use and its connection to hostilities independently of reports that merely describe radiation or an explosion.
- What evidence supports identifying this as nuclear-weapon use rather than another source of explosion or radioactive release? provenance
- What connects the event to armed conflict rather than testing, an accident, or an exercise? boundary
Actors, authority, and attribution Represents who is alleged to have used nuclear weapons and what is known about decision responsibility.
Actor attribution, authorization, and stated intent are separate claims with different evidentiary requirements.
Responsible actors
Tracks claims about participants and responsibility for particular uses.
Attribution evidence
Maintain competing attribution assessments, their sources, and the distinction between public claims and independently supported conclusions.
- Who attributes the nuclear use to which actor, and what evidence does each assessment cite? provenance
- Which claims share an underlying source, and which have independent corroboration? provenance
Authorization and intent
Separates responsibility for execution from evidence about authorization and purpose.
Decision responsibility
Record authorization as established, alleged, disputed, or unknown, and distinguish stated purposes from analysts' interpretations.
- What evidence supports a conclusion about whether the use was authorized, unauthorized, or accidental? provenance
- Which purposes were stated by participants, and which were inferred by observers? boundary
Conflict sequence and escalation Locates nuclear use within a conflict and records changes in its extent without prescribing military employment.
Nuclear warfare must be understood as a sequence whose interpretation can change as evidence accumulates.
Use chronology
Reconstructs the sequence of nuclear use and related hostilities at an appropriate historical or analytical level.
Episode sequence
Record individual use events, temporal uncertainty, and the rationale for grouping them into an episode or exchange.
- Which nuclear-use events are supported by evidence, and what is the uncertainty in their order and timing? measurement
- What rule groups these events into one episode rather than separate episodes? boundary
Escalation interpretations
Examines attributed claims about expansion, restraint, signaling, and interaction with conventional hostilities.
Observed change versus inferred signal
Separate observable changes in participation, geographic extent, or recurrence from interpretations of intended signals and projected next steps.
- Which observable changes support describing the episode as expanding, stabilizing, or contracting? measurement
- Whose interpretation links a threat, doctrine, or conventional event to subsequent nuclear use, and what alternatives remain plausible? provenance
Humanitarian and cascading consequences Organizes assessments of direct harm and wider disruption with explicit evidentiary and modeling limits.
Consequence assessments can cover different mechanisms, populations, and time horizons and cannot be treated as interchangeable.
Direct humanitarian harm
Records deaths, injuries, displacement, exposure, and disruption of essential civilian services.
Impact estimate comparability
Attach population coverage, assessment date, causal categories, uncertainty, and observation method to each impact estimate.
- Which harms are observed or estimated, over what population and period, and with what uncertainty? measurement
- How does the assessment handle overlapping causes of harm and avoid counting the same people more than once? measurement
Longer-term and transboundary effects
Records assessments of persistent contamination, health burdens, food-system disruption, infrastructure dependencies, and possible climate effects.
Cascade evidence and assumptions
Represent each proposed consequence pathway with its supporting evidence, geographical reach, time horizon, and dependencies on scenario assumptions.
- Which longer-term or transboundary consequences are observed, and which are projections? provenance
- Which assumptions most affect estimates of climate, food-system, health, and infrastructure consequences? measurement
Civilian protection and cessation Supports assessment of protective action, humanitarian access, and evidence that nuclear use has ended.
An agent needs to connect uncertain conflict information to responsible assistance and distinguish a pause from established cessation.
Humanitarian response conditions
Records needs, response capacity, access constraints, and current guidance issued by competent authorities.
Needs, capacity, and guidance
Connect affected populations and service failures to verified response information, recording its jurisdiction, currency, and limitations.
- What evidence identifies unmet needs and constraints on medical care, shelter, water, communications, and humanitarian access? measurement
- Which competent authorities provide applicable protective guidance, and what must an agent verify before relaying it? action
Cessation and recurrence
Tracks declarations, observed pauses, monitoring coverage, and conditions relevant to renewed nuclear use.
Cessation evidence
Record who claims nuclear use has ceased, what supports that claim, and the temporal and observational limits of verification.
- What distinguishes a declared cessation, an observed pause, and cessation corroborated within a stated monitoring period? definition
- What new evidence should trigger reassessment of cessation or referral to qualified crisis-response authorities? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
