arrow
Enable an AI agent to recognise a physical arrow, assess its condition and compatibility, and decide whether it may be handled, maintained, stored or used with a specified bow.
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 arrow, assess its condition and compatibility, and decide whether it may be handled, maintained, stored or used with a specified bow.
It can be Identify and document the arrow's assembled configuration; Measure dimensions, mass and balance using stated conventions; Inspect shaft and component integrity using applicable guidance; Assess compatibility with a specified bow setup and intended use; Replace or maintain components where construction and guidance permit; Assign handling, storage, use or retirement restrictions and reassess after relevant events.
Distinguishing features
Evidence identifies the object as a projectile intended for launch from a bow, rather than merely a pointed rod or an arrow-shaped ornament.
The rear interface is intended to engage a bowstring; record absent, unusual or damaged interfaces rather than treating a familiar nock shape as mandatory.
The shaft, front-end assembly and rear-end assembly form or formerly formed one projectile, distinguishing an arrow from an unattached arrowhead or replacement shaft.
Launch-system identification distinguishes bow arrows from crossbow bolts, darts and thrown spears; appearance alone leaves ambiguous cases unresolved.

Characteristics
- Arrow role
- Functional projectile, training item, display item, historical artefact, unfinished assembly, unknown Prevents an arrow-shaped or historical object from being treated as ready for shooting.
- Shaft construction
- Recorded material, construction and manufacturer designation, or unknown Determines which identification, inspection and maintenance guidance is applicable.
- Arrow length
- mm, with measurement endpoints and assembled configuration stated Supports comparison with bow requirements without confusing shaft length and overall length.
- Shaft diameter profile
- mm at named shaft positions Supports component-fit checks and recognition of tapered or otherwise varying shafts.
- Assembled mass
- g or grains, with installed components stated Makes mass-based compatibility checks meaningful for the current assembly.
- Shaft stiffness designation
- Reported spine rating or measured deflection, with units and test convention Avoids comparing stiffness numbers that use different conventions.
- Balance location
- mm from a named datum, with arrow configuration stated Allows configuration changes to be assessed without assuming that equal total mass means equal balance.
- Installed component configuration
- Links or descriptions for point, inserts or adapters, nock and fletching, including absent or unknown components Identifies the actual assembly whose fit and condition must be assessed.
- Bow compatibility assessment
- Specified bow and setup linked to supported, unsupported or unresolved compatibility, with evidence Compatibility belongs to a particular pairing and configuration.
- Inspection disposition
- Unassessed, restricted pending inspection, maintenance required, accepted for specified use, retired Connects observed condition and inspection evidence to permitted next actions.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 10 layers · 10 findings · 21 questions.
Arrow identity and boundary Establishes what the object is and whether it belongs within the registered arrow concept.
The registry has no definition, and pointed projectiles or representations can otherwise be classified as arrows without sufficient evidence.
Projectile identification
Separates bow-projectile identity from appearance and present usability.
Intended launch system
Record evidence of the intended launcher and distinguish original function from the object's current role.
- What marking, documentation, construction evidence or provenance identifies this as a bow-launched arrow? definition
- Is the object a functional projectile, unfinished assembly, replica, display item or historical artefact? boundary
Whole-arrow boundary
Determines whether the record concerns an arrow, its remains or a separate component.
Assembly identity
Record which parts constitute this arrow and whether missing or replaced parts affect its identification.
- Which shaft, front-end and rear-end components are present, absent or detached? definition
- Is this an identifiable incomplete arrow or a standalone component that belongs in a neighbouring model? boundary
Shaft and mass profile Captures the arrow's physical configuration through explicitly defined measurements.
Length, shaft construction, stiffness, mass and balance affect arrow comparison and compatibility, but ambiguous conventions can make their values misleading.
Shaft geometry and stiffness
Records shaft construction and dimensions together with the conventions needed to interpret them.
Interpretable shaft specification
Keep observed dimensions, manufacturer designations and stiffness measurements distinguishable.
- What are the shaft material, construction, length and diameter profile, and where were the measurements taken? measurement
- What source or test convention defines the recorded spine or stiffness value? provenance
Assembled mass and balance
Connects mass and balance measurements to the installed component configuration.
Configuration-specific mass profile
Record total mass and balance location for a named assembly rather than treating them as permanent shaft properties.
- What is the measured total mass, in which unit, and with which components installed? measurement
- Where is the balance point relative to a stated datum, and does that measurement reflect the current assembly? measurement
Point, nock and fletching Describes the arrow's front and rear interfaces and the integrity of their attachments.
An intact shaft does not establish that the point, string interface or fletching is suitable and secure.
Front-end assembly
Records the point and any mounting components as an installed combination.
Point fit and retention
Capture point identity, mounting method, attachment condition and configuration-specific handling requirements.
- What point and mounting components are installed, and what evidence supports their fit to this shaft? provenance
- What inspection establishes whether the point assembly is secure, damaged or incomplete? action
Rear-end assembly
Records the string-engagement interface and any fletching arrangement.
Nock and fletching integrity
Record rear-component type, orientation, attachment and observed defects without assuming that all arrows share one arrangement.
- What nock or other string interface and fletching arrangement does this arrow have? definition
- Are rear components loose, cracked, distorted, missing or displaced relative to their documented configuration? measurement
Bow and use compatibility Assesses the arrow against an identified launcher setup and intended application.
An arrow cannot be declared compatible solely from its appearance, condition or a single nominal rating.
Specified bow pairing
Makes compatibility an evidenced relationship to a particular bow configuration.
Pairing evidence
Record applicable compatibility guidance and the arrow and bow facts needed to apply it.
- Which bow setup is being assessed, including the relevant draw conditions, string interface and arrow support? boundary
- What applicable guidance supports the pairing, and which required arrow or bow measurements remain unknown? provenance
Intended-use fit
Connects the installed arrow configuration to a specific proposed use.
Use-dependent restrictions
Record whether the point and overall arrow configuration meet requirements supplied by the intended activity and target context.
- What use is proposed, and what requirements does it impose on this arrow's point and assembly? boundary
- Does the available evidence support that use, require a configuration change or leave the decision unresolved? action
Damage history and disposition Connects arrow-specific damage observations, relevant events and maintenance to the next permitted action.
Impacts, component changes and incomplete inspections can invalidate a previous assessment of an arrow.
Shaft damage assessment
Records material-appropriate inspection evidence and its limits.
Observed defects and inspection coverage
Locate observed shaft defects and distinguish inspected areas from unknown internal or obscured condition.
- What bends, cracks, splits, splinters, dents or other irregularities are observed, and where along the shaft? measurement
- Which inspection method is applicable to this shaft construction, and what condition can that method leave unresolved? action
Event-triggered reassessment
Tracks events that may change condition or invalidate recorded configuration and compatibility.
Maintenance and use disposition
Record relevant impacts, recovery, repairs and component changes, then assign a supported handling or use decision.
- What impacts, difficult extractions, storage exposures, repairs or component replacements occurred since the last assessment? provenance
- Should the arrow be inspected, maintained, stored with restrictions, accepted for specified use or retired, and what evidence supports that decision? action
- Which measurements and compatibility assessments must be repeated after the recorded change? action
What the second pass must settle
- Does vr.tr.arrow include crossbow bolts and specialised bow projectiles, or do authoritative neighbouring registry entries own them?
- Does an existing Vercy world model already own the physical-arrow concept, requiring a registry link instead of a separate publication?
- Which recognised measurement conventions should govern arrow length, spine and balance across different manufacturers and traditions?
- Which authoritative construction-specific guidance establishes inspection methods, repair limits and retirement criteria?
- How should incomplete arrows, replicas and historical artefacts retain arrow identity while receiving different use and preservation constraints?
