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.

Purpose and description
Enable an AI agent to recognise LEGO construction elements and assemblies, assess their compatibility and condition, and choose feasible building, disassembly and care actions.
LEGO is a branded construction-toy system of reusable, interlocking elements, principally moulded plastic bricks, plates and specialised parts, designed to assemble into models that can be dismantled and rebuilt.
It can be Identify and sort elements by construction family, design, variant and connector geometry.; Compare an available inventory with a specified build and propose explicitly qualified substitutions.; Plan assembly and disassembly steps that account for connector access and trapped elements.; Check proposed connections for alignment, clearance, permitted motion and signs of forced fit.; Inspect loose connections, cracked connectors and modified elements before reuse.; Select care or powered-component integration actions using guidance for the identified parts..
Distinguishing features
Establish whether an element belongs to the LEGO product system using available markings, identifiers and provenance; visual resemblance or connector fit alone does not establish origin.
Identify the construction family and connector type rather than assuming every LEGO element uses the same stud-and-tube interface.
Determine whether the referent is an element kind, a particular piece, a set inventory or an assembled model; these require different identity and completeness judgments.
Distinguish intended reusable connections from glued, cut, deformed or otherwise modified joins.
Separate genuine construction elements from LEGO-branded merchandise that does not participate in the construction system.

- Construction toys made by other manufacturers, except as compatibility or identification references
- Market pricing, resale transactions and investment valuation
Characteristics
- Physical referent
- element kind | individual element | set inventory | loose collection | subassembly | assembly Determines whether the agent should assess identity, quantity, completeness or structural state.
- Construction family
- System | Technic | DUPLO | other identified family | mixed | unresolved Guides connector interpretation without treating family membership as proof of pairwise compatibility.
- Element identification
- Links to identified design, colour or decoration variant, and catalogue records, with confidence Supports replacement and inventory matching while preserving uncertainty about similar-looking parts.
- Connector configuration
- Observed connector types, counts, positions and orientations, such as studs, tubes, pins, axle interfaces, clips and bars Determines what can connect and which motions a connection permits.
- Physical envelope
- Millimetres; stud-grid footprint and plate-height count where applicable Supports clearance and alignment checks without imposing brick geometry on every element.
- Connection condition
- untested | holds as intended | loose | unusually tight | cracked | obstructed Separates nominal compatibility from the behaviour of the actual pieces.
- Inventory completeness
- Required, present, missing and substituted element counts against a named inventory revision Makes completeness relative to a specific build or set reference.
- Assembly topology
- Element-to-element connections, subassembly membership and permitted joint motion Supports build sequencing, movement analysis and disassembly planning.
- Modification status
- unmodified | glued | cut | painted | otherwise modified | unknown Changes assumptions about fit, reversibility, identification and care.
- Powered-component compatibility
- Links among identified motor, hub, power supply, electrical connector and control requirements; not applicable where absent Prevents mechanical fit from being mistaken for electrical or control compatibility.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 19 findings · 33 questions.
Element and set identity Resolve what physical LEGO referent is being described and how confidently it is identified.
A LEGO name or number may identify a set, design or variant rather than the particular piece being handled.
Referent and family
Separate construction-system membership from the level of physical aggregation.
Physical LEGO sense
Record whether the subject is a construction element or collection and which construction family is supported by evidence.
- Does Lego here denote an element kind, one piece, a set inventory or an assembled construction? definition
- Which observed features or product records establish its construction family? provenance
Design and variant
Distinguish part geometry from colour, decoration and production variants.
Identification evidence
Retain identifiers and visible evidence without treating an ambiguous marking or appearance as conclusive.
- Which moulded markings, packaging records or catalogue matches support the proposed element identity? provenance
- Do similar designs differ in connector geometry, decoration or another feature relevant to this build? boundary
Connection geometry Describe how LEGO elements engage, align and move relative to one another.
Build feasibility depends on specific interfaces and clearances, not simply on both pieces being LEGO.
Interfaces and alignment
Locate mating connectors and the geometry needed to bring them together.
Mating interface
Record connector types, orientation and spacing for a proposed connection.
- Which stud, tube, pin, axle, clip, bar or other interfaces are intended to mate? definition
- What connector spacing, insertion depth and surrounding clearance must be checked? measurement
Fit and motion
Evaluate retention, permitted movement and unintended deformation.
Connection behaviour
Distinguish a secure fixed connection from an intended moving joint or a forced fit.
- Should this interface hold rigidly, rotate, slide or release during the intended use? definition
- Does engagement produce visible bending, connector damage, unexpected looseness or restricted intended motion? measurement
- What evidence supports joining these particular elements across construction families? boundary
Inventory and build Relate available elements to a target construction and its assembly sequence.
A pile of genuine pieces can still be incomplete or unsuitable for a particular LEGO build.
Requirements and substitutions
Assess element availability against an explicit reference.
Build readiness
Record missing elements and judge replacements against the actual role of each part.
- Which set version, instruction revision or custom design defines the required inventory? provenance
- How many required elements are present, missing or proposed as substitutions? measurement
- Would each substitution preserve required connections, clearance, strength and appearance? action
Assembly dependencies
Track subassemblies, access constraints and reversible construction steps.
Build and release sequence
Represent the order needed to install or remove elements without trapping connectors or forcing pieces.
- Which subassemblies must be completed or positioned before this connection becomes inaccessible? action
- Which surrounding elements must be removed to release this piece, and can a suitable separator reach it? action
Mechanisms and powered elements Capture functional LEGO assemblies beyond static stacking when such elements are present.
Axles, gears, motors and hubs introduce motion and compatibility requirements that brick inventory alone cannot express.
Mechanical transmission
Describe the intended movement through joints, axles, gears and linkages.
Motion path
Record how input motion reaches moving elements and where travel can be obstructed.
- Which axle, gear or linkage connections transmit motion, and which elements support or constrain them? definition
- What travel range, gear relationship and clearance does the assembled mechanism actually exhibit? measurement
Power and control integration
Resolve the component-specific requirements of powered LEGO assemblies.
Powered system match
Record the identified component ecosystem and required power and control connections.
- Which product documentation identifies the motor, hub, power source and compatible control method? provenance
- Are mechanical mounting, electrical connection and control support each established for the proposed combination? boundary
- How can the mechanism be stopped and its power source accessed in the completed build? action
Condition and reuse Assess whether particular LEGO pieces remain suitable for connection, handling and care.
Wear, cracks, decoration and embedded electronics affect what an agent may do with otherwise correctly identified elements.
Damage and alteration
Inspect areas that determine connection performance and reversibility.
Reuse suitability
Record damage or modification at studs, tubes, clips, sockets and other functional surfaces.
- Are any connectors cracked, distorted, worn, obstructed or bonded with adhesive? measurement
- Should the element be reused, assigned a less demanding role or excluded from the proposed assembly? action
Care and user suitability
Tie cleaning and handling decisions to the actual element and intended users.
Part-specific handling
Check applicable guidance for decorated, electrical and small elements before choosing care or use actions.
- Which manufacturer guidance applies to cleaning this element, including its decoration or electrical components? provenance
- What age markings and handling warnings accompany the identified product, and how do they apply to the intended use? boundary
- What preparation or separation of components is required before the selected cleaning or storage action? 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.
