guillotine
Enable an AI agent to recognise a guillotine, assess its configuration and condition, and determine whether documentation, conservation, access restriction or authorised specialist intervention is appropriate.
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 guillotine, assess its configuration and condition, and determine whether documentation, conservation, access restriction or authorised specialist intervention is appropriate.
A purpose-built judicial beheading machine in which a weighted, typically oblique, blade is released to fall in grooves between two uprights and sever the neck held in a two-part lunette.
It can be Classify the apparatus provisionally from visible configuration and documentary evidence.; Record blade, frame and restraint components without activating the mechanism.; Compare current condition with earlier photographs and conservation records.; Flag uncertain restraint, accessible blade edges or unstable structural members for restricted access and specialist review.; Prepare an evidence-based conservation or display assessment.; Link documented historical claims to the specific apparatus or component they concern..
Distinguishing features
Determine whether a blade-bearing assembly moves along guides in a frame, rather than swinging as an axe or rotating as a saw.
Look for a neck restraint and body-support arrangement to distinguish an execution configuration from a material-cutting machine.
Distinguish the guided blade arrangement from a hinged paper trimmer whose blade sweeps about a pivot.
Establish whether the object contains the relevant mechanism or merely reproduces its visible silhouette as a prop, miniature or static replica.
Require configuration or documentary evidence in addition to the label 'guillotine', because the name alone does not settle the object's subtype.
Scope
+ Identification as an execution apparatus, cutting machine, replica, fragment or unresolved candidate
+ Relationships among the frame, guided blade assembly, support and release mechanism
+ Execution-specific fittings where present, including the neck restraint and body support
+ Completeness, structural condition, blade accessibility and stored mechanical energy
+ Evidence of manufacture, alteration, historical use and reconstruction
+ Conditions governing display, handling, conservation and specialist assessment
- Judicial sentences, execution procedures and legal institutions
- Biographies and personal records of people associated with the apparatus
- Detailed operating, construction or performance-optimisation instructions
- The building, exhibition or collection containing the apparatus
- General models of cutting processes and materials processed by industrial machines
Characteristics
- Identification and confidence
- Execution apparatus; cutting machine; replica or prop; fragment; unresolved, with evidence and confidence Controls which interpretation and assessment questions apply without relying solely on the object's name.
- Blade motion arrangement
- Guided descent; other guided motion; hinged motion; static representation; unknown Helps recognise the mechanism and distinguish superficially similar objects.
- Principal component relationships
- Frame, guides, blade carrier, blade, support, lifting and release components: attached, detached, missing or uncertain Makes completeness and configuration assessable even when the apparatus is dismantled.
- Execution-specific fittings
- Neck restraint and body support: present, absent, reconstructed, not applicable or uncertain Supports subtype identification and records features that may have been removed or reconstructed.
- Physical envelope
- Height, width and depth in millimetres; mass in kilograms where reliably established Supports assessment of display clearance, support requirements and specialist handling.
- Blade assembly and energy state
- Position, attachment, restraint and possible stored energy: observed, documented or unknown An apparently inactive apparatus may still contain a raised mass or another source of hazardous movement.
- Structural and edge condition
- Observed frame damage, loose joints, guide deterioration, blade damage and edge accessibility, with assessment date Informs access restrictions and whether movement or intervention requires specialist assessment.
- Historical component attribution
- Component linked to manufacture, replacement, restoration or reconstruction evidence Prevents a composite or restored object from being treated as wholly original.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 9 layers · 16 findings · 24 questions.
Guillotine identity Establish what the registered object is and which sense of guillotine applies.
The name can refer to materially different apparatuses, and appearance alone cannot establish intended use or authenticity.
Mechanism and use
Separate mechanical recognition from attribution of intended use.
Configuration-based identification
Record the evidence supporting identification as a guillotine and its provisional subtype.
- What observable blade-and-guide arrangement supports identification as a guillotine? definition
- What fittings or records distinguish an execution apparatus from a material-cutting machine? boundary
Object boundary
Identify whether the record concerns an assembled apparatus, a component group or a representation.
Assembly or representation
Make the physical extent and representational status of the recorded thing explicit.
- Does this record concern a complete apparatus, a dismantled assembly, an isolated component or a replica? boundary
- Which detached blade, frame or support components have evidence linking them to this apparatus? provenance
Blade, frame and fittings Record the physical arrangement that gives this guillotine its identity and mechanical constraints.
Assessment depends on the relationships among the guided blade, supporting frame and use-specific fittings.
Guided blade assembly
Describe the blade, carrier and guides as observed components.
Blade and guide configuration
Record blade attachment, guide arrangement and visible departures from the documented configuration.
- Which blade, carrier and guide components are present, missing or substituted? definition
- What visible damage, displacement or obstruction affects the relationship between the carrier and its guides? measurement
Support and use fittings
Describe structural support and fittings that establish how the apparatus was configured.
Frame and restraint arrangement
Record the frame and any neck restraint, body support or alternative work-support fittings without assuming all variants share them.
- Which support and restraint fittings are present, and what evidence identifies their intended role? definition
- Which fittings belong to the documented historical configuration, and which were added for restoration or display? provenance
Mechanical state and access Establish the current physical hazards and the evidence needed before handling or intervention.
Blade mass, accessible edges and uncertain retention can remain consequential even in a museum object or replica.
Blade retention and energy
Record the blade assembly's current position and the basis for judging unintended movement.
Retention state
Distinguish directly observed restraint from an unverified assumption that the mechanism is inactive.
- Where is the blade assembly, and what evidence establishes whether its current retention has been assessed? measurement
- Does uncertainty about raised mass, connected drive components or retention require access restriction pending specialist assessment? action
Structural condition and intervention
Connect deterioration of the apparatus to permissible handling, display and conservation actions.
Handling and display constraints
Record how frame stability, blade accessibility and component attachment constrain proposed actions.
- What cracks, corrosion, loose joints or detached parts affect the frame's support of the blade assembly? measurement
- What documented conditions must be met before this apparatus can be moved, displayed or conserved? action
Historical identity and conservation Track evidence of the apparatus's origin, attributed use and material changes.
A guillotine's historical identity may depend on disputed attribution or replacement components, which directly affects interpretation and conservation.
Attribution and use evidence
Separate documented associations from inference or repeated labels.
Apparatus-specific attribution
Tie claims about manufacture, location and historical use to evidence identifying this particular object.
- Which marks, inventories, photographs or custody records identify this particular apparatus? provenance
- Which claims of historical use are supported for this object, and which concern only a similar apparatus or general type? boundary
Alteration and material integrity
Record replacement, reconstruction and conservation changes that affect interpretation.
Component change history
Preserve distinctions among surviving historical material, later repairs and reconstructed parts.
- Which blade, frame, lifting or restraint components were replaced or modified, and what records support those dates? provenance
- Would a proposed conservation or display change remove evidence needed to distinguish historical material from reconstruction? 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.

Regional variation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- French and English name the machine after Joseph-Ignace Guillotin, who proposed a uniform humane method in 1789 but did not design or build it; contemporaries also used louisette/louison after Antoine Louis.
- In German-speaking practice the usual term is Fallbeil: typically a heavier blade, shorter drop, and often an enclosed wooden frame rather than the tall open French scaffold.
- Britain had earlier sliding-axe machines (Halifax Gibbet, Scottish Maiden) but did not adopt the 1792 French machine; the United States never made it a standard method. French colonial use left local names (for example Vietnamese máy chém).

Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- paper-cutting guillotine (stack cutter) - Cuts clamped stacks of sheet material on a table; it is a print-shop or office machine (Wikidata Q5450227), not a lunette-and-uprights beheading apparatus.
- Halifax Gibbet - An earlier English sliding-axe beheading machine at Halifax; same falling-blade principle, but a distinct pre-1792 device not built to the Louis-Schmidt pattern.
- Scottish Maiden - A sixteenth-eighteenth-century Scottish falling-blade machine; predecessor, not a French guillotine.
- executioner's sword or axe - Decapitation by a hand-delivered blow; no grooved uprights, mouton, or triggered drop.
- gallows - Kills by hanging, not by a falling blade through the neck.
- tonsil guillotine (surgical) - A small handheld instrument for amputating tonsils; named by analogy, not a judicial machine.
- flying guillotine - A legendary or cinematic thrown-collar weapon (separate registry item), not a scaffold-mounted falling blade.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of guillotine this model covers, and on what evidence? provenance

What the second pass must settle
- Does vr.tr.guillotine cover only execution apparatuses, or also industrial and office cutting machines bearing the name?
- Does an existing Vercy world model already cover this concept and therefore need to be linked rather than duplicated?
- Which configuration differences across documented guillotine variants require optional features rather than identification requirements?
- What evidence threshold should distinguish an original apparatus, a composite restoration, a reconstruction and a replica?
- Which specialist assessment criteria and applicable local requirements should govern handling, display and conservation for each included subtype?
