go
Enable an AI agent to recognise physical Go equipment, assess whether it supports an intended game, and decide how it may be arranged, used or maintained, provisionally interpreting the undefined PHY.OBJ entry "go" as a Go set.
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.

Purpose and description
Enable an AI agent to recognise physical Go equipment, assess whether it supports an intended game, and decide how it may be arranged, used or maintained, provisionally interpreting the undefined PHY.OBJ entry "go" as a Go set.
A physical Go set is the board, stones, and bowls used to play the board game of Go (weiqi/baduk), a two-player territorial game of perfect information.
It can be Identify and group the board, stones and containers belonging to a set.; Check whether the grid and available stones suit an explicitly stated intended game.; Record stone locations using a declared board orientation and coordinate convention.; Place or remove an identified stone at a specified intersection under an external game instruction.; Preserve or reconstruct an arrangement from a verified physical record.; Sort, store or maintain components according to their observed materials and handling requirements..
Distinguishing features
The intended placement locations are grid intersections rather than the interiors of alternating squares.
The playing pieces form two visually distinguishable groups of stones rather than differentiated piece roles such as those used in chess.
Board markings and stones alone do not establish Go identity: similar equipment can support other games, so intended use must also be recorded.
A complete physical set includes compatible stones and a playing surface; an isolated board or container should be identified as a component unless the registry explicitly includes it.
Scope
+ The board's intersection grid and usable playing surface
+ The two distinguishable groups of playing stones
+ Compatibility between stone size and grid spacing
+ Stone containers and the completeness of an identified set
+ Physical arrangement of stones and its preservation during handling
- Go as an abstract game, including authoritative rules and scoring systems
- A particular match's turn history, result and adjudication
- Player identity, rank and skill
- Strategy, move evaluation and teaching curricula
- Digital Go software and online game services
Characteristics
- Identity evidence
- Links to labels, supplier descriptions, owner statements or other evidence identifying intended use A grid board with two stone colours does not uniquely identify Go equipment.
- Grid dimensions
- Number of intersection lines along each axis Establishes the available placement locations and compatibility with an intended game.
- Grid spacing
- Millimetres between adjacent lines on each axis Determines whether neighbouring stones can be placed and distinguished reliably.
- Stone dimensions
- Diameter and thickness in millimetres, including variation within each group Supports fit assessment, handling and identification of mismatched replacements.
- Stone group distinction
- Observed colours and any supplementary tactile or visual distinctions An agent must distinguish the two sides under actual lighting and sensing conditions.
- Stone inventory
- Count by group and location: board, supply container, captured-stone area or unassigned Supports readiness checks without confusing stones in play with missing equipment.
- Placement readability
- Clear, partly ambiguous or unreadable, with affected intersections identified Determines whether a physical arrangement can be recorded or restored confidently.
- Component condition
- Observed grid wear, surface distortion, stone damage and container defects Connects specific defects to placement, recognition, handling and storage decisions.

Go set identity Establishes whether the object is intended as Go equipment and which components the model represents.
The undefined name and equipment shared with neighbouring games make identification and component boundaries essential.
Intended game
Separates physical resemblance from evidence that the equipment is intended for Go.
Evidence of Go use
Records the basis and uncertainty of identifying the equipment as a Go set.
- What label, accompanying instructions or owner statement identifies this equipment as intended for Go? provenance
- Could the observed board and stones instead be equipment for another intersection-placement game? boundary
Set membership
Identifies the board, stones and containers included in the represented object.
Component boundary
Distinguishes a complete set, a partial set and a separately registered component.
- Does this instance represent an entire Go set, a board alone or another explicitly identified subset? definition
- What evidence associates these particular stones and containers with this board? provenance
Intersection surface Describes the board as a physical system of identifiable stone-placement locations.
An agent must resolve intersections, orientation and physical fit before it can observe or manipulate a Go position.
Grid geometry
Captures the grid dimensions and spacing actually present on the board.
Playable intersections
Records the placement grid without assuming a standard board size.
- How many grid lines exist along each axis, and are all their intersections usable? measurement
- What is the spacing along each axis, and can the supplied stones occupy adjacent intersections without obstructing one another? measurement
Board orientation
Connects the physical board to a stable reference frame for observation and placement.
Coordinate reference
Makes recorded intersections recoverable even when the board lacks printed coordinates.
- Which physical edge or external reference establishes the origin and direction of the recorded coordinates? definition
- How will the agent detect board rotation or movement before acting on a previously recorded intersection? action
Stone populations Describes the two groups of stones, their physical suitability and their distribution across the set.
Go manipulation depends on distinguishing otherwise similar pieces and maintaining a usable supply for both sides.
Stone distinction and fit
Assesses whether individual stones can be classified, placed and handled reliably.
Usable stone groups
Records group distinctions and dimensional variation relevant to the board and handling method.
- Can every stone be assigned reliably to one of the two groups under the intended lighting or sensing conditions? measurement
- What diameter, thickness or shape variations affect placement on this grid or pickup by the intended handler? measurement
Stone inventory and containment
Tracks available stones and the physical locations used to keep them separated.
Stone availability
Distinguishes available supply, placed stones, captured stones and genuinely missing components.
- How many stones of each group are on the board, in supply containers, in captured-stone areas or elsewhere? measurement
- Which containers or designated areas keep supply stones distinguishable from captured stones for the intended game procedure? definition
Position preservation and use Connects observable stone placement and equipment condition to permitted physical actions.
An apparently minor displacement or cleanup can destroy a meaningful Go arrangement, while physical observation alone cannot determine move legality.
Observable position
Records physical occupancy while retaining uncertainty and referring game interpretation to a match model.
Intersection occupancy
Associates visible stones with intersections and identifies placements that cannot be resolved confidently.
- Which intersections are empty or occupied by each stone group, and which assignments are ambiguous because of displacement or occlusion? measurement
- Which linked match record or explicit instruction supplies turn, capture and legality information that the physical arrangement cannot establish? boundary
Handling and readiness
Determines whether equipment can be used or moved while respecting its condition and any arrangement being preserved.
Position-sensitive actions
Connects placement defects, component damage and preservation requirements to handling decisions.
- Do worn grid lines, board instability or damaged stones prevent reliable recognition, placement or removal at particular intersections? measurement
- Before moving, cleaning or packing the set, must the current arrangement be preserved, and what verified record would support restoration? 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 registry entry vr.tr.go actually denote physical Go equipment, the game itself or another referent named "go"?
- Does an existing Vercy world model already own this concept, requiring a link instead of a separate publication?
- Should this registry entry encompass complete sets, individual boards and travel variants, or do existing neighbouring entries own those components?
- Which intended playing contexts and authoritative equipment references should determine board compatibility and sufficient stone inventory?
- Where should persistent position records belong when the set carries a teaching arrangement, puzzle or unfinished match?
