covering
a natural object that covers or envelops
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 agent to recognise a natural covering, assess how it covers or envelops something, and judge whether observation, disturbance, removal or restoration is appropriate.
A covering is a natural material layer that forms over, around, or on the surface of another body and thereby conceals, protects, or bounds it.
It can be Locate and map covered areas, margins and openings.; Inspect or measure thickness and passage through the covering using methods appropriate to its attachment and fragility.; Compare observations to detect spreading, thinning, breach or detachment.; Assess whether lifting, parting or removing a portion would expose or damage the covered subject.; Where authorised and supported by evidence, retain, reposition or remove the covering and monitor the resulting exposure..
Distinguishing features
An identifiable natural object physically overlies, surrounds or envelops an identifiable subject or region; proximity alone is insufficient.
The candidate has a defensible physical boundary at the stated observation scale; a substance name alone does not identify a covering.
The covering relationship can be described through overlap or enclosure, rather than inferred solely from a protective function.
Evidence distinguishes the candidate from an intentionally manufactured cover; ambiguous or modified examples require an explicit boundary decision.
The candidate can be distinguished from the covered subject at least anatomically or spatially, even if separation would damage either.
Scope
+ The natural object identified as the covering and the evidence for that identification
+ The surface, object or region covered or enveloped
+ Coverage geometry, continuity, thickness and openings
+ Attachment, separability and interaction with the covered subject
+ Changes in coverage and constraints on disturbing it
- Manufactured covers, containers, coatings and packaging
- The complete anatomy, physiology or lifecycle of a covered organism
- The composition and properties of a substance independent of its occurrence as a covering
- The complete structure and condition of the covered object
- Figurative covering, concealment or protection without a physical natural object
- The process that produces a covering except where it explains its present state or likely change
Characteristics
- Natural-origin evidence
- observed natural formation; documented natural origin; inferred natural origin; unresolved Determines whether the candidate meets the registry definition without treating appearance as proof.
- Covered subject
- identified object, surface or region, with the covered portion specified A covering must be recognised through a concrete physical relationship.
- Coverage configuration
- overlying; partially surrounding; fully enveloping; mixed; unresolved Distinguishes different geometries and helps locate accessible surfaces.
- Surface coverage
- 0-100% of an explicitly defined reference surface, with method and uncertainty Makes completeness assessable without confusing a visible projection with total coverage.
- Thickness distribution
- mm or m at specified locations, with range and measurement method Local thinning or thickening may change separation, exposure and passage through the covering.
- Coverage continuity
- continuous at stated resolution; naturally open; newly breached; patchy; unresolved Distinguishes expected openings from changes that expose the covered subject.
- Interface attachment
- loose contact; interlocked; adherent; structurally continuous; mixed; unresolved Helps judge whether moving the covering would affect the covered subject.
- Passage through covering
- agent-specific measure, such as light transmission in %, water flux in mm/h or particle passage by size; conditions required Coverage alone does not establish an effective barrier.
- Coverage trajectory
- expanding; stable over stated interval; thinning; fragmenting; detaching; re-forming; unresolved Supports decisions about monitoring and the likely consequences of delay.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 11 findings · 21 questions.
Covering identity Establish which natural object is acting as a covering and what it covers.
A covering is identified by both its natural origin and its physical relationship to another subject.
Natural object boundary
Determine the candidate's origin and defensible extent as one object.
Candidate and origin
Record the candidate's observable boundaries and the evidence that it is natural, including uncertainty about aggregates or human modification.
- What bounded natural object is being identified as the covering, and at what observation scale? definition
- What observation or record supports its natural origin, and what human modification is known? provenance
Covered subject
Identify the subject and the physical relationship that makes this object its covering.
Physical covering relation
Specify what is overlain or enveloped and distinguish coverage from adjacency or incidental contact.
- Which object, surface or region does this covering overlie or envelop? definition
- Where does the covering end and the covered subject begin, including any inseparable interface? boundary
Coverage geometry Describe the extent, thickness and openings of the covering relative to its subject.
An agent needs to know precisely what remains covered and what is exposed.
Extent and enclosure
Record how much of the subject is covered and from which directions.
Coverage footprint
Describe overlap or enclosure against an explicit reference surface and observation method.
- What proportion of the defined reference surface is covered, and how was that proportion established? measurement
- Does the covering overlie one side, surround several sides or fully envelop the subject, and which regions remain unobserved? boundary
Thickness and openings
Locate variations in covering depth and interruptions in continuity.
Local coverage variation
Record thickness variation and distinguish observed openings without presuming that every opening is damage.
- How does thickness vary across the covering, and which measurements are direct rather than inferred? measurement
- Where are gaps, pores or breaks, and what evidence distinguishes expected openings from newly exposed areas? boundary
Interface and exchange Describe how the covering contacts its subject and what can pass across it.
Physical coverage does not by itself establish attachment, protection or isolation.
Contact and attachment
Characterise the interface and the dependence of covering and subject on their connection.
Attachment and separability
Record how the covering is held in place and the evidence concerning separation.
- Where is the covering loose, adherent, interlocked or structurally continuous with its subject? boundary
- What evidence indicates whether separation would tear the covering, injure the subject or disrupt their interface? action
Passage and effects
Assess specific exchanges or exposures associated with the covering.
Evidenced barrier behaviour
Record observed passage and effects separately from assumed protective functions.
- How much light, water, gas, heat or relevant particulate matter passes through the covering under specified conditions? measurement
- What observations support a claimed effect on the covered subject, and do they distinguish that effect from other causes? provenance
Coverage change Track formation, loss and movement that alter the covering relationship.
A covering can remain present while losing continuity, attachment or extent.
Formation and renewal
Record how this covering came to occupy its position and whether it is being renewed.
Coverage history
Distinguish observed formation or renewal from an origin inferred solely from appearance.
- What evidence explains how this object came to cover the subject? provenance
- What repeated observations show accumulation, growth, replacement or other renewal of coverage? measurement
Loss and displacement
Identify changes that uncover the subject or relocate the covering.
Changing exposure
Record thinning, fragmentation, detachment or displacement in terms of their effect on exposure.
- Which regions have become thinner, detached or uncovered between dated observations? measurement
- What evidence connects these changes to shedding, erosion, movement or another process? provenance
Covering intervention Support decisions about inspecting, retaining, disturbing or removing the covering.
Changing a covering changes access and exposure and may affect an attached natural subject.
Inspection access
Determine how to observe the covering or its concealed interface with acceptable disturbance.
Inspection method
Match an inspection method to the needed observation and the covering's continuity and attachment.
- Can the required observation use an existing opening or a method that leaves coverage intact? action
- If parting or sampling is necessary, which area can be disturbed and what evidence supports that choice? action
Alteration and follow-up
Evaluate changes to coverage and define observations needed after intervention.
Coverage action decision
Record the basis for retaining, repositioning or removing the covering, including uncertain consequences and recovery.
- Given attachment, observed effects and applicable permission constraints, which changes to coverage are justified? action
- After a change, what exposure, subject condition and re-coverage observations would determine whether further action is needed? 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.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.
Kinds and varieties
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- integument
- bark
- husk
- rind
- shell
- membrane
- crust
- pelt
- Which of these kinds and varieties hold for the sense of covering this model covers, and on what evidence? provenance
What the second pass must settle
- Does the registry intend covering to include attached anatomical structures, loose natural accumulations and environmental layers, or are some assigned exclusively to neighbouring entries?
- What makes a collection of natural particles or organisms one covering object rather than several objects participating in a covering relationship?
- How should naturally formed coverings that are relocated or substantially modified by people be classified?
- Which coverage and passage measurements are appropriate for each admitted subtype, and what reference surfaces make them comparable?
- Which existing Vercy models already own particular natural coverings, requiring a reference or shared interpretation rather than a duplicate model?
