space suit
Enable an AI agent to recognise a space suit, assess its documented readiness for a particular wearer and mission, and identify permitted use, servicing or withdrawal actions.
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 space suit, assess its documented readiness for a particular wearer and mission, and identify permitted use, servicing or withdrawal actions.
A space suit is a wearable, self-contained pressure garment and life-support interface that keeps a human alive and functional in vacuum, low pressure, or other extra-vehicular and intra-vehicular space environments by providing pressurization, breathing gas, thermal control, and protection from debris and radiation.
It can be Match a configured suit to a wearer, mission role and documented operating environment.; Identify required external services, compatible interfaces and missing components before use.; Compare inspection and test evidence with configuration-specific acceptance criteria.; Assess whether resource state and documented limits support a proposed activity and its required reserves.; Identify authorised inspection, servicing or component-replacement procedures and subsequent verification requirements.; Flag restrictions, quarantine conditions and matters requiring qualified human release..
Distinguishing features
Determine whether the item is documented as a wearable pressure-protection system intended for human spaceflight, rather than identifying it from appearance alone.
Distinguish it from an aviation pressure suit by its documented spaceflight role, qualified configuration and spacecraft or EVA interfaces; pressure retention alone is insufficient.
Distinguish the complete configured suit from a helmet, cooling garment, pressure garment or life-support pack that is only one component.
Distinguish operational hardware from a replica or training article using its designation, pressure-system functionality and restrictions on human use.
Distinguish intravehicular protection from extravehicular capability by documented operating conditions and support dependencies, without assuming every space suit supports EVA.
Scope
+ Suit identity, configuration and intended intravehicular, extravehicular or contingency role
+ Pressure envelope, closures, seals and pressure-control provisions
+ Integrated or connected breathing, ventilation and thermal-control provisions
+ Wearer fit, mobility, visibility, communication and task interfaces
+ Protective layers, mission-specific environmental limits and exposure history
+ Inspection, servicing, consumables and use restrictions for the configured suit
- Spacecraft cabin atmosphere and vehicle-wide environmental control
- Wearer medical condition, qualifications and training records
- Mission planning, EVA task allocation and flight rules as independent authorities
- Airlock operation and habitat infrastructure beyond their suit interfaces
- Independent tools, propulsion devices and restraint systems beyond their suit compatibility
- Manufacturing facilities and supply-chain management beyond evidence attached to suit components
Characteristics
- Intended operational role
- intravehicular; extravehicular; contingency; multiple documented roles; unresolved Determines which environments and activities the suit may support.
- Configured assembly
- Suit assembly linked to installed component identities, revisions and compatibility evidence Readiness applies to a particular assembly, not merely a suit family name.
- Operating pressure envelope
- kPa, with absolute or differential reference, operating mode and permitted range Connects pressure protection to the conditions under which it has been established.
- Measured leakage
- Recorded leak-rate unit with test pressure, temperature, method, date and acceptance criterion Supports a traceable judgement about pressure-envelope integrity.
- Life-support dependency
- vehicle supplied; portable supply; hybrid; other documented arrangement Identifies the external services or carried resources required in each operating mode.
- Supported duration
- minutes, conditional on configuration, resource state, workload, environment and reserve policy Prevents a nominal endurance figure from being treated as an unconditional safe-use period.
- Wearer fit assessment
- Wearer linked to sizing configuration, assessment evidence and unresolved restrictions A serviceable suit may still be unsuitable for a particular wearer.
- Pressurised task mobility
- Task-specific reach, joint range in degrees or actuation force in N, with test conditions Establishes whether required movements and controls remain usable under operating conditions.
- Environmental qualification
- Configuration linked to documented exposure limits, test evidence and exclusions Prevents intended protection from being mistaken for demonstrated protection.
- Operational readiness
- unassessed; awaiting checks; released for specified use; restricted; quarantined; retired Makes permitted actions depend on current evidence and the applicable release authority.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 11 findings · 21 questions.
Suit role and configuration Identifies what assembly counts as this suit and which spaceflight roles its configuration supports.
Similar-looking suits and interchangeable-looking parts can have different capabilities and use restrictions.
Operational identity
Separates intended role, hardware designation and demonstrated capability.
Spaceflight role
Record the suit's designated role and the evidence distinguishing operational hardware from training or display equipment.
- Is this suit designated for intravehicular use, extravehicular use, contingency protection or a documented combination? definition
- Which authoritative record establishes this article's identity and restrictions on human use? provenance
Assembly boundary
Defines the fitted assembly and its relationship to detachable or externally supplied equipment.
Qualified component combination
Record installed components and the evidence that their combination supports the claimed role.
- Which helmet, gloves, pressure garment, protective layers and life-support components belong to this configured suit? boundary
- What compatibility evidence and repeat checks are required when one of these components is exchanged? action
Pressure and breathing support Captures the pressure envelope and provisions for maintaining a usable breathing environment.
Pressure retention and breathing support must be assessed together with their operating modes and dependencies.
Pressure envelope
Covers the pressure-retaining assembly, seals, closures and pressure-control provisions.
Pressure integrity evidence
Record applicable pressure limits and measured integrity of the current assembly.
- What operating and differential-pressure limits apply to this configuration and mode? measurement
- What do the latest applicable leakage and closure checks show against their documented acceptance criteria? measurement
Breathing loop and supply
Identifies gas supply, circulation, carbon-dioxide management and dependencies on external equipment.
Breathing support availability
Record how breathing support is provided in each mode and what evidence establishes its availability.
- Which breathing-support functions are carried by the suit, and which depend on a vehicle, umbilical or other connected system? boundary
- What measurements and resource estimates establish adequate breathing support for the proposed workload and duration? measurement
Thermal and environmental protection Relates thermal management and protective construction to the exposures expected in a particular use.
Protection depends on exposure conditions and configuration; the label 'space suit' does not establish universal environmental resistance.
Heat and moisture management
Covers removal or retention of heat and management of moisture within the worn suit.
Thermal support envelope
Record thermal-control provisions, required services and demonstrated limits under relevant workloads.
- Which garments, circulation paths and heat-rejection provisions manage wearer heat and moisture in this configuration? definition
- Under what workload, environmental and resource conditions has adequate thermal performance been established? measurement
Exposure-specific protection
Connects protective components to documented hazards, limits and degradation mechanisms.
Protective coverage and limits
Record evidenced protection against relevant exposures without inferring capability from the presence of an outer layer.
- Which records establish protection and limits for relevant hazards such as abrasion, dust, impact, optical exposure or contact temperature? provenance
- Which exposures exceed the suit's documented protection or require separate controls? boundary
Wearer fit and task performance Establishes whether a particular wearer can occupy, operate and perform assigned activities in the suit.
Suit integrity alone does not establish usable fit, access to controls or task capability when pressurised.
Fit and body interface
Covers sizing, adjustment, body contact and access for donning and removal.
Wearer-specific fit
Record the fitted configuration and assessment of constraints affecting the named wearer.
- Which sizing components and adjustments were assessed for this wearer, and under what pressurisation conditions? measurement

Task access and control
Record evidence that the wearer can perform required movements and use relevant interfaces in operating conditions.
- Can the wearer reach and operate required suit controls, tools and restraint interfaces with the selected gloves at operating pressure? measurement
- What verified limits on visibility, hearing, communication, reach or dexterity constrain the proposed task? boundary
Use readiness and recovery Connects suit condition, resource availability and fault handling to permission for a specified use.
A qualified design can still be unavailable for use because of damage, expired evidence, depleted resources or unresolved faults.
Condition and service evidence
Tracks suit-specific wear, exposure, component life and verification after servicing.
Current serviceability
Record findings from inspection and servicing that affect pressure protection, life support or protective performance.
- What damage, contamination, seal degradation or accumulated use affects the installed components, and which acceptance criteria apply? measurement
- Which servicing actions and subsequent tests remain necessary before this assembly can be released for its intended use? action
Mission readiness and contingencies
Relates operating resources, fault indications and recovery provisions to a specific planned activity.
Bounded use release
Record the conditions of operational release and applicable responses when support is degraded.
- What limiting resource, required reserve and unresolved restriction bound the proposed use, and who has authority to release it? action
- Which approved responses apply to loss of pressure, breathing support, cooling, power or communication in this configuration? 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.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.

- Which of these kinds and varieties hold for the sense of space suit this model covers, and on what evidence? provenance
Sources
- pending research - will be filled after lookups
What the second pass must settle
- Does the registry intend 'space suit' to include historical partial-pressure designs and non-operational training articles, or should these be linked neighbouring concepts?
- Where should the canonical assembly boundary fall for detachable life-support packs, cooling garments and emergency breathing equipment across different suit families?
- Which authoritative suit-family documents provide operating limits, inspection criteria, component compatibility and release procedures?
- How should readiness evidence transfer between configurations when components, wearers or operating roles change?
- Which environmental protection claims are demonstrated for each suit family, and which remain unqualified or dependent on mission-level controls?
