match
Enable an AI agent to recognise an ignition match, assess its condition and suitability, and determine whether it may be stored, struck, extinguished or discarded.
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 an ignition match, assess its condition and suitability, and determine whether it may be stored, struck, extinguished or discarded.
It can be Identify and classify a match using its form and available product evidence.; Inspect the head and stem for damage, moisture exposure and prior use.; Associate the match with its documented striking requirements.; Assess whether striking and flame transfer are permitted and suitable in the current setting.; Track an authorised ignition attempt through burning and extinction.; Determine whether the remaining item should be retained, set aside or discarded under applicable instructions..
Distinguishing features
Look for a consumable stem or strip carrying a distinct ignition head, rather than identifying every small combustible stick as a match.
Establish that its intended function is to initiate a small flame for transfer, rather than to sustain illumination or provide a decorative effect.
Check whether ignition is intended to occur through a specified striking interaction, distinguishing it from a wick supplied by a fuel reservoir.
Distinguish one match from a matchbook or box containing several; record attachment to a book without treating the whole book as one match.
Use packaging, markings or documented provenance to distinguish match types when appearance alone is inconclusive.
Scope
+ An individual match, including its head and supporting stem or strip
+ Match type and its required striking interface
+ Physical integrity, moisture exposure and evidence of prior use
+ Ignition, flame transfer, extinction and residual heat
+ Item-specific handling constraints and disposition
- Matchboxes, matchbooks and their collective inventory or packaging design
- Striker surfaces as independently maintained objects
- Lighters, fire steels and other ignition devices
- The object or fuel being lit and the resulting larger fire
- Manufacture of match compositions
- Sporting matches, paired correspondences and computational matching
Characteristics
- Match type
- Safety; strike-anywhere; specialty type as documented; unknown Determines which ignition requirements need to be established.
- Stem construction
- Wood; paper or card; other documented construction; unknown Helps identify the match and assess how damage affects handling.
- Overall length
- mm Helps assess whether the available grip and reach suit the intended use.
- Head integrity
- Apparently intact; chipped; partly missing; absent; indeterminate Separates visible damage from an unsupported assumption that the match remains usable.
- Stem integrity
- Intact; bent; split; broken; indeterminate Affects whether the match can be held and struck in a controlled way.
- Moisture condition
- Apparently dry; damp; wet; previously wetted; unknown Records exposure relevant to usability without assuming that a dry appearance proves recovery.
- Compatible striking interface
- Link to a documented compatible striker or surface requirement; unverified; unknown Prevents treating an arbitrary rough surface as suitable.
- Use and combustion state
- Apparently unused; struck without sustained flame; flaming; glowing; extinguished with heat unresolved; cooled residue; unknown Distinguishes readiness, failed use and conditions that still require attention.
- Source package
- Link to originating box, book or product record; unknown Preserves access to type identification, instructions and exposure history.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 10 layers · 10 findings · 20 questions.
Match identity Establishes that the item is an ignition match and identifies the individual being assessed.
The registry name is ambiguous, and an individual match must be distinguished from both other ignition devices and its packaging.
Ignition-match recognition
Connects observable construction to evidence of intended ignition use.
Headed consumable form
Record the observed head and supporting stem or strip, together with evidence that the item is intended for striking ignition.
- What observed features and product evidence support identifying this item as an ignition match? definition
- Could this instead be a taper, splint or another small combustible item? boundary
Individual and origin
Separates the match from the box or book that supplies its context.
Match unit and package link
Record which physical match is under assessment, whether it remains attached to a book and which source package is known.
- Is the assessed unit one loose match or one identifiable strip still attached to a matchbook? boundary
- Which package or product record establishes its origin and stated type? provenance
Striking requirements Records the match's ignition class and the interface required for an appropriate striking attempt.
A match's appearance does not by itself establish which surfaces or handling instructions apply.
Documented match type
Identifies the ignition category without guessing from head colour or shape.
Type evidence
Record whether the match type is documented, tentatively identified or unknown.
- What label or manufacturer instruction identifies the match as safety, strike-anywhere or a specialty type? provenance
- Which ignition requirements remain unresolved if the source package is missing? definition
Striker compatibility
Relates the individual match to an available, suitable striking interface.
Usable striking interface
Record compatibility evidence and any observed condition that prevents relying on the available striker.
- What evidence establishes that the available striking interface is suitable for this match? provenance
- Do missing instructions or an unsuitable striker require deferring the ignition attempt? action
Unspent match condition Assesses the head, grip-bearing stem and relevant exposure before use.
An apparently unused match may still have damage or exposure that makes its performance uncertain.
Head and stem integrity
Examines the parts needed to hold and strike the match.
Physical readiness
Record head loss, cracks, bending and the remaining usable stem without equating visual integrity with guaranteed ignition.
- Is the head intact, and is the supporting stem split, bent or broken? measurement
- Does the remaining stem provide an appropriate grip and reach for the intended use under its instructions? action
Moisture and surface exposure
Separates current appearance from known wetting or contamination history.
Exposure-related uncertainty
Record observed dampness, foreign material and known exposure, preserving uncertainty about subsequent usability.
- What current moisture or foreign material is visible on the head and stem? measurement
- Is prior wetting or contamination known, and what product guidance addresses continued use? provenance
Ignition and flame transfer Connects a permitted use to the observed outcome of striking and carrying the flame to its target.
Successful use requires distinguishing an ignition attempt, sustained burning and ignition of the intended target.
Intended lighting task
Records what the match is intended to light and the conditions governing that action.
Permitted flame transfer
Link the target and setting to the decision to use this match, keeping the target's own properties in its neighbouring model.
- What specific target is this match intended to ignite? boundary
- Do the setting, applicable instructions and available grip permit a controlled striking and flame-transfer attempt? action
Attempt and burning observation
Tracks what actually happened when the match was used.
Observed ignition outcome
Distinguish no sustained flame, a burning match, successful target ignition and an interrupted attempt.
- Did the attempt produce no sustained flame, a brief flare or continuing flame on the match? measurement
- Was flame transferred to the intended target, or must the attempt end with extinction of the match? action
Extinction and disposition Tracks residual burning and decides the next disposition of a used, failed or damaged match.
Loss of visible flame and completion of the lighting task do not by themselves establish that the remaining match is ready for disposal.
Residual combustion
Separates visible extinction from unresolved glow or heat.
Extinction evidence
Record observed flame, glow and available evidence of cooling, leaving unobserved conditions unknown.
- Is flame or glow still observable on the head or charred stem? measurement
- What evidence supports treating the residue as cooled rather than merely without visible flame? measurement
Remaining item disposition
Determines what to do with the match after inspection or an ignition attempt.
Retain, set aside or discard
Record the chosen disposition and its basis in head condition, prior use, residual heat and relevant instructions.
- Is the remaining item an unused match, a unsuccessfully struck match, a damaged match or spent residue? definition
- What applicable instructions and observed condition support retaining, setting aside or discarding it? action
What the second pass must settle
- Does vr.tr.match mean an ignition match, as provisionally assumed from PHY / PHY.OBJ, or another physical referent?
- Does an existing world model already own this concept, requiring a registry link instead of a separate publication?
- Which specialty match types belong within this entry, and which require additional ignition or extinction questions?
- What authoritative product evidence can establish striker compatibility and the treatment of wet, damaged or unsuccessfully struck matches?
- What observable criteria and applicable instructions should govern cooling confirmation and disposal in the intended deployment settings?
