Purpose and description
Enable an AI agent to recognise a physical envelope, assess its suitability and condition for enclosing flat contents, and decide how it may be filled, closed, addressed, opened or recovered.
An envelope is a flat, flexible container, usually made from folded and joined paper with a closable flap, used to enclose documents or other relatively thin items for delivery, protection or storage.
It can be Select an envelope for specified contents using measured fit and protection needs.; Insert and orient contents while preserving flap clearance and any window alignment.; Close or secure the envelope using its identified closure mechanism.; Address or label an appropriate surface and check readability.; Inspect and open the envelope with a method suited to content position and authorised access.; Assess whether the envelope can be reused or separated into locally accepted recovery streams..
Distinguishing features
Has a preformed pocket with an insertion opening, distinguishing it from a loose sheet used to wrap contents.
Its ordinary enclosure form accommodates substantially flat contents, distinguishing it from a general-purpose sack or bag.
Retains contents within a pocket rather than only between folding panels, distinguishing it from an unsealed document folder.
Uses a flexible body rather than a self-supporting rigid container, distinguishing it from a box.
Is a physical enclosure; the registry plane excludes the mathematical, architectural and signal-processing senses of envelope.

- Envelope manufacturing machinery and printing equipment
Characteristics
- Envelope format
- plain, windowed, lined, padded, expanding, other; categories may overlap Identifies construction differences that affect content fit, visibility and handling.
- External dimensions
- width and height in mm, with flap position and measurement orientation recorded Supports physical identification and comparison with a specified handling requirement.
- Usable internal dimensions
- clear width, insertion depth and opening width in mm Nominal exterior size does not establish whether an article can pass the opening and fit inside.
- Filled thickness
- mm at the thickest point under a recorded measurement method Bulging contents can strain seams, obstruct closure or change handling eligibility.
- Body construction
- paper, polymer film, composite or other; seams, lining and padding recorded separately Affects tear resistance, printing, protection and material recovery.
- Opening and flap geometry
- opening on long edge or short edge; flap shape and overlap Determines insertion orientation and the area available for closure.
- Closure mechanism
- moisture-activated adhesive, pressure-sensitive adhesive, clasp, string-and-button, tuck flap, none or other Determines the closing action, needed consumables and whether reopening is intended.
- Closure condition
- open, closed but unsecured, secured, partially detached, opened or uncertain Separates flap position from actual retention and avoids assuming that a closed flap is sealed.
- Content visibility
- not assessed, concealed, partly visible or readable under recorded lighting Supports privacy assessment without assuming that paper or a printed lining makes contents unreadable.
- Window geometry
- window width, height and offsets in mm from identified edges; absent where applicable Determines whether the intended address remains visible as the insert moves.
- Intended contents
- references to contents with dimensions, stiffness, edge hazards and sensitivity Envelope suitability depends on what it must enclose and protect.
- Physical integrity
- intact, torn, punctured, seam-separated, wet, distorted or uncertain; multiple conditions allowed Determines whether the envelope can retain contents and tolerate further handling.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 19 findings · 29 questions.
Pocket and content fit The envelope's enclosure geometry and its compatibility with actual contents.
An exterior size designation alone cannot establish insertion clearance or a safe filled configuration.
Pocket geometry
Opening orientation, seam intrusions and usable interior space.
Usable pocket
Record the clear space available after allowing for seams, lining and closure overlap.
- Which edge opens, and what are the clear opening width and usable insertion depth in millimetres? measurement
- Where do seams, padding or folds reduce the space available to contents? boundary
Filled configuration
Fit after insertion, including bulging, movement and flap clearance.
Content fit
Assess the proposed contents in their intended folded or unfolded configuration.
- What are the contents' dimensions and the resulting maximum filled thickness? measurement
- Can the contents be inserted and the flap secured without forcing, damaging or trapping them? action
Closure and opening How the insertion opening is secured, inspected and reopened.
Envelope closures differ in activation, retention, reopening behaviour and evidence left by access.
Securing the flap
Closure mechanism, readiness and required closing action.
Closure readiness
Identify the closure and establish whether it remains usable.
- What mechanism secures the opening, and does it require moisture, liner removal or mechanical engagement? definition
- Is the adhesive or fastener usable, and what instructions support the closing method? provenance
Access and reclosure
Opening consequences and the limits of visible seal evidence.
Opening evidence
Record visible closure changes without treating appearance as proof of an uninterrupted seal.
- What tears, adhesive disturbance, detached edges or fastener changes are observable? measurement
- Where can this envelope be opened with the least risk to its contents, and can its closure then be reused? action
Concealment and protection The body, lining and seams as barriers around enclosed contents.
Enclosing an article does not by itself establish privacy, cushioning or resistance to moisture and tearing.
Visibility barrier
Visibility through the body, lining and any intentional apertures.
Concealment assessment
Assess what information can be read or inferred through the filled envelope.
- Under the intended handling conditions, can text or identifying shapes be seen through the body or lining? measurement
- Which information is intentionally exposed, and which must remain concealed? boundary
Physical barrier
Material construction and evidence for protection relevant to the contents.
Protection evidence
Distinguish observed construction from tested or documented protective performance.
- What body material, lining, padding and seam construction are present? definition
- What evidence supports any claimed resistance to wetting, puncture, tearing or impact? provenance
Address display and handling How the envelope presents routing information and meets a selected handling context.
Windows, moving inserts, labels and filled geometry directly affect whether an envelope can be identified and handled as intended.
Address presentation
Address placement on the exterior or through a window.
Stable address display
Check that routing information stays readable in the filled configuration.
- Where is the address displayed, and what are the window or label dimensions and edge offsets? measurement
- After the insert shifts within the pocket, does the complete intended address remain visible without exposing unintended information? measurement
Handling compatibility
Assessment against the requirements of a named postal service, feeder or other handling system.
Context-specific acceptance
Attach handling conclusions to identified requirements and the actual filled envelope.
- Which service or equipment requirements apply, and what issuing body, version or date identifies them? provenance
- Do the filled dimensions, mass, flexibility, closure and address placement satisfy those requirements? boundary
Damage, reuse and recovery Envelope-specific deterioration and options after opening or failed closure.
A spent adhesive strip, torn opening or mixed-material window can change what may be done with an otherwise usable pocket.
Retention condition
Damage that compromises the pocket or opening.
Escape and snag points
Locate tears, gaps and exposed components that threaten retention or handling.
- Are there holes, separated seams or flap gaps through which these contents could escape? measurement
- Can the damage be repaired for the intended use, or should the contents be transferred to another enclosure? action
After-use options
Reclosure, obsolete markings and separation of envelope components.
Reuse or separation
Assess another use or material recovery from the envelope's remaining construction.
- Can the envelope be secured again and obsolete addresses or routing marks removed or obscured for its next use? action
- Which windows, liners, padding or fasteners require separation under the identified local recovery guidance? 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.

What the second pass must settle
- Does this registry entry include padded mailers and expanding document envelopes, or do neighbouring entries own those boundaries?
- Which envelope size and terminology standards should be referenced for the catalogue's intended jurisdictions?
- What repeatable methods should assess usable capacity, opacity and closure retention without implying unsupported performance ratings?
- What evidence is sufficient to describe a particular envelope as tamper-evident, and what access methods remain outside that evidence?
- Does an existing Vercy world model already own this physical-envelope concept and therefore need to be linked instead of duplicated?
