Thing Registry Physical world and living systems #artifact

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 physical connecting instrumentality, assess whether it connects its intended endpoints adequately, and determine which installation, use, inspection or separation actions are permissible.

an instrumentality that connects

It can be Identify the artifact and map its interfaces to intended and actual endpoints.; Evaluate a proposed endpoint pairing against documented interface and service requirements.; Plan or perform authorised engagement, securing and functional verification.; Inspect or test retention and continuity using criteria appropriate to the connecting function.; Determine whether service conditions require restriction, isolation, repair or replacement.; Plan or perform authorised separation and assess whether the artifact may be reused..

Distinguishing features

An identifiable physical artifact performs the connecting role; two things merely touching does not by itself identify such an artifact.

Its connecting role can be described by identifying the physical things or interfaces it joins, even when those endpoints are temporarily absent.

Its own physical features provide attachment, continuity, retention or another connecting mechanism, rather than merely indicating that a relationship exists.

A loose or disengaged connecting artifact can retain its identity as a connection artifact while failing to establish a current connection.

A connector, fastener, adapter, cable or similar named object may satisfy this definition; its name alone does not establish a separate registry concept.

Scope

+ The connecting artifact and the boundary separating it from its endpoints

+ Endpoint interfaces, mating requirements and attachment arrangements

+ How the artifact establishes and maintains a physical connection

+ What the connection carries, transmits, constrains or holds together

+ Conditions governing connection integrity, use and disconnection

- The complete models of the objects or systems being connected

- Abstract associations, social connections and informational links without a physical connecting artifact

- A contact or joint understood only as a relationship or location

- The substance, energy or information conveyed through the connection

- The architecture and operation of the wider network containing the connection

Characteristics

Artifact boundary
Single component, bounded assembly, integrated connecting feature, or unresolved Establishes what the agent is assessing and which parts belong to neighbouring objects.
Endpoint assignments
Artifact interface mapped to intended and currently attached physical endpoint Distinguishes correct connection, wrong connection and an unoccupied interface.
Interface compatibility
Compatible, conditionally compatible, incompatible, or unverified for each proposed endpoint Physical fit alone may not establish suitability for the intended connection.
Connecting mechanism
Recorded mechanism, such as threaded engagement, latching, bonding, clamping or interference fit Determines how the connection is established, retained, inspected and released.
Connecting function
One or more of mechanical restraint, load transfer, fluid passage, electrical continuity, optical continuity, or another specified physical function Defines what successful connection means for this artifact.
Engagement state
Disengaged, partially engaged, engaged but unsecured, secured, or unknown, per interface where applicable Separates apparent attachment from a connection ready for its intended use.
Relative motion behaviour
Restrained or permitted translation and rotation, with the relevant directions identified Movement can be an intended capability or evidence of loss of connection.
Function-specific limits
Applicable quantities and units, such as N, N·m, Pa, A, V or °C, with their conditions and evidence Supports comparison of intended service with verified connection limits.
Connection performance
Applicable observations such as retention force in N, leakage in mL/min, resistance in Ω or optical loss in dB, with test conditions Provides evidence that the artifact performs its particular connecting function.
Separation and reuse status
Recorded separation method, whether separation is destructive, and verified or unresolved reuse eligibility Prevents an agent from assuming that a connection can be opened or reinstalled safely.

Drafted structure

Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 10 layers · 10 findings · 20 questions.

Connecting artifact and endpoints Identify the physical instrumentality and the things it is intended to join.

An agent must distinguish the artifact from the relationship it creates and from the objects at its ends.

Artifact boundary

Locate the physical extent of the connecting instrumentality.

Bounded connecting unit

Record the component or assembly treated as the connection artifact, including uncertain boundaries.

  1. Which physical component or assembly performs the connecting role? definition
  2. Which mating features belong to this artifact, and which belong to the connected objects? boundary

Endpoint mapping

Distinguish intended attachment arrangements from current attachments.

Intended and actual endpoints

Record the physical endpoint assigned to each interface, including vacant or incorrectly occupied interfaces.

  1. What physical endpoints is each interface intended to connect? definition
  2. Which endpoints are currently attached, and how was that mapping verified? provenance
Mating and retention Describe how endpoints fit the artifact and remain connected.

A connection can appear to fit while lacking compatibility, full engagement or adequate retention.

Interface compatibility

Capture the requirements for a valid physical pairing.

Valid mating conditions

Record applicable geometry, orientation, material and interface specifications for each endpoint.

  1. Which dimensions, interface specifications, orientations or material combinations determine a valid pairing? definition
  2. What documentation or inspection establishes compatibility with the proposed endpoint? provenance

Engagement and securing

Describe the mechanism and evidence of established attachment.

Retained engagement

Record how engagement is achieved, how unintended separation is resisted and whether securing is complete.

  1. What mechanism establishes engagement and prevents unintended separation? definition
  2. Which observable or measurable condition distinguishes partial engagement from correctly secured engagement? measurement
Connecting function Define what the artifact enables or constrains between its endpoints.

Successful connection depends on the intended physical effect, not attachment alone.

Transfer and continuity

Identify what passes through or across the artifact and what must remain separated.

Intended physical paths

Record required paths for load, matter, energy or signals, including directionality and isolation where applicable.

  1. What must this artifact transmit or carry between which interfaces, and in which directions? definition
  2. Which paths, channels or surrounding regions must remain isolated from one another? boundary

Mechanical relationship

Identify the spatial relationship the connection must maintain or permit.

Restraint and permitted motion

Record required positioning, permitted movement and constraints imposed between endpoints.

  1. Which relative translations or rotations must the connection restrain, permit or accommodate? definition
  2. What observed movement or displacement would indicate departure from the intended relationship? measurement
Service fitness and integrity Assess whether the established connection can perform under its actual conditions.

A secured artifact may still be unsuitable for its load, environment or required continuity.

Service envelope

Relate applicable connection limits to the intended service.

Supported service conditions

Record evidenced limits and the conditions under which those limits apply.

  1. Which loads, pressures, electrical quantities, temperatures, movements or exposures constrain this connection's intended use? measurement
  2. What source or test establishes those limits for this artifact and endpoint combination? provenance

Integrity evidence

Assess loss of retention, continuity, isolation or positional control.

Connection condition assessment

Record relevant defects, functional test results and unresolved inspection limitations.

  1. What inspection or test results establish the present quality of retention and the required connecting functions? measurement
  2. Which observed conditions require restricted use, isolation, repair or replacement? action
Connection and separation actions Define supported transitions into service, out of service and back into service.

Connecting and disconnecting alter endpoint support and physical pathways, so an agent needs explicit action conditions.

Establishing service

Identify preparation, engagement and verification requirements.

Installation and release to use

Record the applicable procedure and evidence required before treating the connection as usable.

  1. What endpoint preparation, alignment, tools and securing sequence are required to establish this connection? action
  2. What checks must pass before the connected assembly may enter its intended service? action

Separation and reconnection

Identify how the connection can be opened and whether it can subsequently be restored.

Controlled separation and reuse

Record separation prerequisites, expected damage and conditions for reuse or replacement.

  1. What support, isolation, unloading or containment is required before releasing or removing this artifact? action
  2. After separation, what evidence determines whether the artifact and its securing or sealing elements may be reused? action

What the second pass must settle

  • Does this registry entry include integral connecting features, deposited joining materials and bonded joints, or only separately identifiable artifacts?
  • How does the registry relate this entry to connector, coupling, fastener, adapter and cable entries, and does an existing world model already provide the authoritative coverage?
  • When several components jointly establish one connection, what determines whether they form one connection artifact or multiple registered things?
  • Which connection families require specialised extensions, and which interface, retention and performance concepts can reliably be shared?
  • What evidence and acceptance criteria should govern state judgments for undocumented, custom-made or inaccessible connections?
