hostage
Enable an AI agent to recognise a person's possible hostage status, assess their captivity and welfare, and identify protective actions within its authority.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a person's possible hostage status, assess their captivity and welfare, and identify protective actions within its authority.
A hostage is a person seized, detained, or otherwise held whose killing, injury, or continued detention is threatened in order to compel a third party (a State, organisation, or person) to do or abstain from an act, as an explicit or implicit condition for that person's release or safety.
It can be Assess and revise possible hostage status from attributable evidence.; Connect captivity reports to demands, threats and the parties involved.; Flag stale welfare evidence, urgent needs and unresolved contradictions for responsible responders.; Preserve the person's expressed wishes together with evidence of monitoring or coercion.; Route relevant information through authorised protective channels while restricting exposure of sensitive details.; Record and verify release, escape, transfer or other outcomes without prematurely closing the captivity episode..
Distinguishing features
Look for evidence that continued confinement or threatened harm is being used to influence another party; inability to leave alone does not establish hostage status.
Distinguish kidnapping as an act of taking or moving a person from hostage status as a coercive role; movement need not be established to assess the latter.
Distinguish a missing person from a suspected hostage by requiring evidence connecting their disappearance to captivity and coercive leverage.
Do not treat a detention label, including prisoner or detainee, as decisive: examine whether continued detention is being made conditional on another party's conduct.
Distinguish voluntary presence from captivity by examining whether the person can safely refuse demands and leave, rather than relying solely on a recorded statement of consent.
Scope
+ Evidence that a person is confined or prevented from leaving
+ The connection between captivity, threatened consequences and demands on another party
+ Relationships among the captive person, captor and party being pressured
+ The person's welfare, communication access and expressed wishes
+ Protective response constraints and verification that hostage status has ended
- The person's full identity, biography and enduring attributes
- The captor organisation's complete structure and activities
- The overall kidnapping, siege, armed conflict or criminal investigation
- Clinical diagnosis and treatment planning
- Negotiation strategy, ransom transactions and tactical rescue operations
- Formal legal determinations of offences, liability or detention status
Characteristics
- Hostage-status assessment
- suspected | supported | disputed | ended | unresolved Separates an evidence-supported assessment from an allegation and avoids treating past captivity as current.
- Freedom to leave
- prevented | apparently possible | verified restored | unknown Tests whether apparent access to movement or communication amounts to actual freedom.
- Coercive relationship
- person held ↔ captor or controlling party ↔ party being pressured Identifies who controls captivity and whose conduct the captivity is intended to influence.
- Demand and threatened consequence
- recorded demand, intended recipient, threatened consequence and claimed release condition; each may be unknown or disputed Makes the alleged connection between captivity and compelled conduct explicit.
- Time in captivity
- hours or days, with estimated bounds and an as-of time Supports welfare assessment while preserving uncertainty about when captivity began or ended.
- Latest welfare evidence
- reported or observed condition, observation time, source and verification status Prevents an old or coerced communication from being treated as assurance of current safety.
- Communication conditions
- independent | monitored | captor-mediated | unavailable | unknown Affects how statements, requests and apparent consent should be interpreted.
- Protective response authority
- responsible responder, authorised action, referral route and applicable restrictions Connects assessment to permitted protective action without assuming authority to negotiate or intervene.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 33 questions.
Hostage status and evidence Establish whether this person is being held as coercive leverage and how strongly the available evidence supports that assessment.
Hostage status must be distinguished from disappearance, confinement and unverified claims.
Captivity basis
Examine whether the person is prevented from leaving.
Constrained departure
Record the evidence of physical confinement, threats or other control that prevents departure, including conflicting accounts.
- What prevents this person from leaving or refusing continued custody? definition
- Who observed or reported that restriction, and when? provenance
Coercive status test
Evaluate whether captivity is being used to influence another party.
Leverage evidence
Separate direct evidence of conditional detention or threatened harm from inference based on disappearance or association.
- What evidence connects this person's continued captivity or threatened harm to conduct demanded of another party? definition
- Which alternative explanation remains plausible, and what evidence would distinguish it? boundary
Captor demands and parties Describe the coercive relationship without assuming that a claimant controls the captive person.
Understanding whose conduct is being compelled and who controls release is central to recognising the hostage role.
Control and claims
Distinguish physical custody, asserted responsibility and claimed authority over release.
Custody versus claim
Record separately the reported custodian, the party making demands and any intermediary.
- Who reportedly holds the person, and who claims to speak for that holder? provenance
- What supports the claim that the demanding party can determine continued detention or release? boundary
Conditional demands
Represent what another party is being pressed to do and how that demand relates to captivity.
Demand-threat link
Capture attributed demands, intended recipients, deadlines and threatened consequences without treating promises as reliable.
- Who is being asked to do or refrain from doing what, and what consequence is attached to refusal? definition
- What is the source and timing of each demand, deadline or claimed release condition? provenance
- Have demands changed, conflicted or been withdrawn while captivity continued? measurement
Captivity welfare and voice Track the person's reported condition and ability to communicate under captivity.
Captivity restricts both access to necessities and the reliability of apparent reassurance or consent.
Condition and needs
Assess the recency and limits of evidence about survival, injury and essential needs.
Current welfare evidence
Record the latest attributable observations and reported unmet needs, separating observation time from receipt time.
- What is the most recent evidence of the person's condition, and when was it actually observed? measurement
- What urgent needs or threats are reported, and which require assessment by a qualified responder? action
- What limits the authenticity, completeness or independence of this welfare evidence? provenance
Communication and agency
Preserve the person's voice while accounting for monitoring and coercion.
Expressed wishes under control
Record what the person communicates, the conditions of communication and uncertainty about freedom of expression.
- Could the person communicate privately, or was the message monitored, scripted or relayed? boundary
- What wishes or requests did the person express, and what evidence supports their attribution? provenance
- How can those wishes inform protective decisions without assuming that a coerced statement establishes consent? action
Protective action and information Connect the hostage assessment to authorised protective handling of communications and sensitive information.
Information disclosure or uncoordinated contact can affect the captive person's exposure and the response to their captivity.
Response authority
Identify who is responsible for protective decisions and what the agent is authorised to do.
Authorised protective route
Record the established responder and referral route for urgent welfare reports or new captor communications.
- Which responder or service has an established responsibility for this captivity episode? provenance
- Which protective actions may the agent take, and which require a responsible human decision? action
Sensitive captivity information
Determine how information about the person and captivity can be shared for a protective purpose.
Disclosure and contact constraints
Identify case-specific restrictions on sharing identity, location, messages or family contacts and on initiating contact.
- Which details could expose the person or their contacts to additional coercion if disclosed? boundary
- Who is authorised to receive each relevant detail, and through which established channel? action
- What case-specific instructions govern contacting the captive person, captor or intermediaries? action
Captivity transitions and resolution Track changes in custody and distinguish claimed outcomes from verified endings.
A transfer, release announcement or loss of contact does not by itself establish that hostage status has ended.
Custody continuity
Follow the hostage role across transfers and interruptions in evidence.
Transfer and contact gaps
Record changes in reported control and determine whether confinement and coercive leverage continue.
- Has custody reportedly changed, and what evidence connects the person before and after that change? provenance
- Does the new situation continue the coercive captivity, end it or leave its status unknown? boundary
Verified outcome
Establish what happened to the person and when the hostage role ceased.
End of hostage status
Distinguish claimed release, verified freedom, continued detention under another status, reported death and unresolved disappearance.
- What evidence establishes the outcome and its effective time independently of a captor's announcement? provenance
- If the person remains confined, what supports ending the hostage assessment while retaining a detention assessment? boundary
- What welfare handoff or unresolved verification must remain active after the hostage role ends? 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.

Real-world use
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Police crisis-negotiation units treat a live third-party demand plus a held person as a hostage incident, as distinct from a barricade with no victim.
- Parties to armed conflict detain civilians to coerce opposing forces, communities, or outside States; prosecutors charge that conduct as the war crime of taking hostages.
- Kidnap-and-ransom (K&R) insurers, corporate security, and foreign ministries handle employees seized for money or political leverage in high-risk countries.
- Aircraft, ship, embassy, school, and prison sieges are organised as hostage incidents with inner perimeters, negotiators, and (sometimes) tactical rescue.

- Which of these real-world use hold for the sense of hostage this model covers, and on what evidence? provenance
Typical measurements
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Duration of detention - minutes to hours in express or barricade cases; days to years in conflict and political kidnapping - hour (or day)
- Number of persons held - 1 in most criminal cases; tens to hundreds in institutional, school, or mass-transport sieges - person
- Number of captors - 1-small cell in crime; organised units in conflict or terrorism - person

- Payment of ransom or political concession that finances or incentivises further seizures.
- Severe psychological injury after release, including PTSD and coercive bonding.
- Mislabeling prisoners of war or security detainees as hostages (or the reverse), which distorts targeting, negotiation, and later prosecution.
- Collective punishment, reprisals, or stigmatisation of families and communities associated with the incident.
- Which of these failure modes and hazards hold for the sense of hostage this model covers, and on what evidence? provenance
Regional variation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- United States federal law splits hostage-taking (third-party compulsion, 18 U.S.C. § 1203) from kidnapping (18 U.S.C. § 1201); many other systems fold both into kidnapping or abduction offences.
- England and Wales implemented the 1979 Convention in the Taking of Hostages Act 1982 while keeping common-law kidnapping as a separate offence.
- In armed conflict, IHL applies the hostage prohibition regardless of how domestic criminal codes name the conduct.
- Latin American practice distinguishes secuestro exprés (very short detention for immediate cash or ATM use) from longer political or ransom kidnapping.
- Japanese 'hostage justice' (hitojichi-shiho) is a false friend: it refers to prolonged pretrial detention of suspects, not hostage-taking of a third person.
- Which of these regional variation hold for the sense of hostage this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Kidnap victim / abductee - Kidnapping is taking or carrying away a person; hostage-taking additionally uses that person as leverage to compel a third party. A kidnapped person is a hostage only when that coercive condition is present.
- Prisoner of war - A POW is a captured combatant entitled to Geneva Convention III protections and may not lawfully be used as a bargaining chip; a hostage is held to compel a third party and is not a lawful status.
- Security detainee or civilian internee - Internment can be lawful in occupation or conflict for imperative security reasons; it becomes hostage-taking only if the detention or a threat against the person is used to compel someone else.
- Human shield - A human shield is used to deter attack on a military objective by presence; a hostage is held under threat to extract an act or omission from a third party. The two can overlap in one person but are distinct legal wrongs.
- Convicted prisoner or ordinary arrestee - Lawful custody under criminal procedure lacks the extra-legal seizure-plus-third-party-compulsion structure that defines a hostage.
- Enslaved person or forced labourer - The primary wrong is ownership or labour exploitation; hostage-taking is instrumental use of the person to coerce a third party, not (primarily) extraction of work.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of hostage this model covers, and on what evidence? provenance

What the second pass must settle
- Does Vercy already have a world model that owns hostage status or the broader coercive-captivity relationship, requiring this registry entry to link to it?
- Should the registry concept require a demand directed at a third party, and how should cases involving demands solely on the captive person be classified?
- What evidence threshold should distinguish suspected, supported and disputed hostage status when demands are implicit or communications cannot be authenticated?
- How should collective hostage situations be represented while preserving each person's distinct custody, welfare and release status?
- Which authoritative sources and jurisdiction-specific interpretations should inform the boundary between hostage status and other forms of detention?
