discus throw
Enable an AI agent to recognise a discus-throw activity, assess its readiness and attempt status, and determine which execution, recording or adjudication actions are appropriate.
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 discus-throw activity, assess its readiness and attempt status, and determine which execution, recording or adjudication actions are appropriate.
It can be Classify a proposed activity as discus competition, practice or a specific discus drill.; Check the selected discus against the referenced event or practice requirements.; Hold or clear an attempt using recorded throwing-area checks and authorised signals.; Record delivery observations, landing evidence and distance without conflating them with an official decision.; Flag a possible foul or disputed measurement for the responsible official.; Determine whether another attempt, implement retrieval or session closure is permitted..
Distinguishing features
The activity uses a discus as the thrown implement; a spherical shot, shaft-like javelin or tethered hammer indicates a neighbouring discipline.
The intended outcome is a distance throw into a designated landing area, rather than a pass to a receiver or a flying-disc target game.
A competition attempt is associated with a throwing circle and landing sector; a practice adaptation must be identified explicitly.
A standing delivery or partial-turn drill can remain discus-throw practice; completion of a full rotational technique is not an identity requirement.
Scope
+ Identification of discus throw and the particular practice or competition format
+ Suitability of the selected discus for the participant and applicable requirements
+ Readiness of the throwing circle, landing sector and protective arrangements
+ Execution and observable state of individual throwing attempts
+ Attempt adjudication, distance recording and progression through a throwing session
- Athlete identity, medical history and general fitness
- Discus manufacturing, ownership and inventory management
- Facility construction and maintenance programmes
- Administration of an athletics meeting beyond its discus event
- Other throwing disciplines and flying-disc games
- Long-term coaching plans and training-load management
Characteristics
- Activity format
- competition attempt | practice attempt | technique drill Determines which completion, measurement and adjudication expectations apply.
- Applicable requirements
- Referenced ruleset and edition, event conditions or practice instructions Makes implement eligibility and attempt decisions traceable to the requirements actually in force.
- Selected discus mass
- kg, with measured or declared status Supports checking whether the selected implement suits the event category or practice task.
- Implement acceptance
- unchecked | accepted | rejected | unresolved Separates possession of a discus from evidence that it may be used for this attempt.
- Throwing-area readiness
- unchecked | ready | held | closed Controls whether a throw may begin under the local safety procedure.
- Delivery form
- standing | partial turn | rotational | other described drill Allows observations and distances to be interpreted against the technique task.
- Attempt phase
- awaiting clearance | preparing | delivering | released | awaiting decision | closed | aborted Identifies which actions and observations remain possible.
- Attempt decision
- pending | valid | foul | passed | aborted | disputed | unadjudicated practice Prevents an observed throw or measured distance from being treated automatically as an accepted result.
- Throw distance
- m, with measurement method, precision and official or practice status Supports comparison while preserving the basis and authority of the measurement.
- Attempt position
- Participant, event or session, round and attempt sequence Places each throw within the correct progression and prevents results from being assigned to the wrong attempt.

Discus activity boundary Establishes what kind of discus activity is taking place and which requirements govern it.
A competition throw and a standing practice drill share an implement but require different judgments about completion and outcome.
Activity recognition
Identifies the intended discus task and distinguishes neighbouring activities.
Discus task identity
Records evidence that the task is discus throwing, including its implement, intended outcome and delivery format.
- What identifies this as discus throw rather than another athletics throw or a flying-disc activity? definition
- Is this a complete distance attempt or a named drill with a narrower completion condition? boundary
Governing context
Connects the activity to competition requirements or explicit practice instructions.
Applicable throw requirements
Records the authority and category needed to interpret implement suitability and attempt decisions.
- Which ruleset edition, event category or practice instructions govern this throw? provenance
- Which adaptations change the usual implement, throwing position or attempt procedure? boundary
Discus selection and condition Captures whether the actual discus is suitable and accepted for the intended attempt.
Distance and validity cannot be interpreted reliably without knowing which implement was thrown and whether it met the applicable requirements.
Implement fit
Relates the selected discus to the event category or training task.
Selected discus specification
Records implement identity and the specification evidence relevant to its intended use.
- Which discus is selected, and what evidence establishes its mass and any other required dimensions? measurement
- Does that specification match the participant's event category or the stated purpose of the drill? boundary
Implement release readiness
Captures condition and acceptance checks before the discus is used.
Discus condition and acceptance
Records observed damage, surface condition and any required inspection decision.
- What rim, body or surface condition could affect handling or acceptance of this discus? measurement
- Who has accepted the implement for use, or what check must occur before it can be thrown? action
Throwing environment and clearance Represents the circle, landing area and protective arrangements as conditions for starting or holding a throw.
A discus attempt depends on a usable delivery surface and controlled access to the area through which the implement may travel.
Circle, sector and protection
Records the physical setup used for delivery and landing assessment.
Throwing-area configuration
Identifies the circle or practice position, sector boundaries and applicable protective setup.
- Which circle or practice position and landing boundaries define this attempt? definition
- What checks establish that the delivery surface and protective arrangements are suitable under the applicable procedure? provenance
Throw and retrieval clearance
Separates permission to throw from permission to enter the landing area.
Landing-area control
Records clearance signals, access restrictions and conditions that require an attempt to be held.
- Who or what confirms that the landing area is clear and this throw may begin? provenance
- What observed condition requires a hold, and what signal permits measurement or discus retrieval? action
Delivery and attempt boundaries Captures the delivery sequence and observable events relevant to completing and judging an attempt.
A release alone does not establish a completed valid attempt; delivery, contact and exit observations may also matter.
Delivery observation
Describes the executed technique at a level useful for recognising the task and comparing attempts.
Executed discus delivery
Records the delivery form, throwing hand and observed progression to release or abandonment.
- Which hand and standing, partial-turn or rotational delivery were actually used? measurement
- Did the sequence reach discus release, or was it interrupted or abandoned before release? boundary
Circle contact and exit
Preserves observations needed to assess delivery-area boundaries and completion procedure.
Attempt boundary evidence
Records relevant contacts and the location and timing of exit without replacing the authorised ruling.
- What contact with the circle rim or surrounding ground was observed, and at what stage? measurement
- Where and when did the thrower leave the circle, and how does that evidence relate to the applicable requirements? boundary
Landing, result and progression Connects landing evidence to measurement, adjudication and the next permitted event action.
A useful discus record must distinguish physical distance from an accepted result and establish what follows the attempt.
Landing and distance
Establishes the relevant landing evidence and the basis of any distance value.
Landing mark and measurement
Records the identified landing mark, its relationship to the sector and the measurement procedure used.
- Which observed landing mark belongs to this discus, and where is it relative to the sector boundaries? measurement
- What distance was recorded, using which reference points, method and precision? measurement
Decision and next attempt
Records the authoritative attempt status and its consequences for session or competition progression.
Accepted attempt outcome
Links the decision, supporting evidence and any unresolved dispute to the correct attempt.
- What is the attempt decision, who made it, and which observation or requirement supports it? provenance
- Does this outcome permit another attempt, require review or close the participant's throwing sequence? action
What the second pass must settle
- Which governing ruleset, edition and competition categories must the model support, including any adapted or seated discus formats?
- Which implement specifications, inspection evidence and handling restrictions are required for each supported category?
- What exact circle-contact, exit, landing-boundary and timing rules determine attempt validity under each supported ruleset?
- Which facility checks, protective configurations and clearance procedures must be recorded for competition and practice settings?
- What measurement, rounding, attempt-allocation and result-comparison procedures apply, and how should disputed decisions be represented?
