heavyweight
Enable an agent to identify the heavyweight division in mixed martial arts, assess weight-class eligibility under a specified ruleset, and identify decisions requiring an official ruling.
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.

MMA heavyweight identity Establishes which heavyweight concept a record denotes.
Sport and referent
Checks that the record concerns an MMA weight division.
MMA division reference
Recognition requires both the MMA context and a classification-level referent.
- What evidence identifies this heavyweight reference as a mixed martial arts division? definition
- Does the reference denote the division itself, an athlete, or a championship? boundary
Local division meaning
Connects the label to the classification system in which it is used.
Label and authority
A local heavyweight designation needs an explicit authority context before its boundaries can be interpreted.
- Which authority or promotion uses this heavyweight designation? provenance
- Does its published terminology equate this label with another division name? definition
Heavyweight weight boundaries Defines the applicable mass interval and its exact interpretation.
Division interval
Captures verified lower and upper bounds without assuming a universal interval.
Boundary values
An eligibility comparison needs the governing limits and their inclusive or exclusive operators.
- What lower and upper weight limits does the applicable heavyweight definition specify? measurement
- Which endpoints are inclusive, and is any absent limit explicitly documented? boundary
Units and allowances
Controls how measurement units and contest-specific allowances affect the interval.
Operative weight comparison
The comparison must preserve the governing unit, precision, and any expressly applicable allowance.
- Which unit and rounding convention govern an official heavyweight weight comparison? measurement
- What documented allowance, if any, applies to this contest, and under what conditions? boundary
- Would conversion or rounding change the apparent eligibility result at a boundary? measurement
Heavyweight rule applicability Selects the definition that governs a particular contest or historical record.
Governing rule selection
Resolves which published heavyweight conditions control the assessment.
Controlling definition
Conflicting promotion and regulatory descriptions require an evidenced determination of applicability.
- Which published heavyweight rule governs this event in its jurisdiction? provenance
- If promotion and regulator descriptions differ, what establishes which condition controls? action
Temporal and contest context
Binds the selected rule to the event date and relevant contest category.
Applicable rule version
A heavyweight assessment must use the version and contest conditions applicable to the event being assessed.
- Was this heavyweight definition effective on the event date? provenance
- Which title status or competition category changes the applicable heavyweight conditions? boundary
Heavyweight eligibility evidence Connects official weight evidence to a bounded eligibility assessment.
Official weigh-in record
Identifies the measurement accepted for the contest.
Accepted weight evidence
The assessment needs an attributable official measurement and clarity about any replacement reading.
- What official weigh-in record provides the competitor's weight, unit, event, and measurement time? provenance
- If there are multiple readings, which one was accepted for heavyweight eligibility and by whom? measurement
Assessment and ruling
Separates the weight comparison from the competent authority's disposition.
Weight status and disposition
An agent can report compliance with verified weight conditions while recording any official exception or unresolved ruling separately.
- Does the accepted measurement satisfy the applicable heavyweight boundaries and allowance? measurement
- What official ruling addresses a missed limit, disputed reading, or requested exception? action
- Which missing evidence prevents a definitive weight eligibility assessment? provenance
Heavyweight neighbouring classifications Locates heavyweight among adjacent divisions and distinguishes it from negotiated contest terms.
Adjacent MMA divisions
Records heavyweight's neighbours within the same governing system.
Division boundary mapping
Adjacent divisions must be identified from the applicable system rather than inferred from familiar names.
- Which division directly precedes heavyweight in this ruleset, and how do their limits meet? boundary
- Does this ruleset provide a heavier division, and what distinguishes it from heavyweight? boundary
Catchweight and title boundaries
Separates official division designation from negotiated weight and championship conditions.
Contest designation
A bout's weight agreement and title conditions need independent evidence before they determine its heavyweight classification.
- Is the contest officially designated heavyweight or catchweight, and where is that designation recorded? provenance
- Does a revised weight agreement change the division designation, title eligibility, or both? boundary
- Who must confirm the classification after the contest's weight terms change? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.

What it is Filled
Heavyweight is a weight category in boxing and several other combat sports, with eligibility defined by the rules of the particular sport and governing body.
In scope
- MMA-specific heavyweight identity and terminology
- Weight boundaries under a named authority and ruleset version
- Official weigh-in evidence relevant to heavyweight eligibility
- Title-bout and non-title-bout weight conditions where applicable
- Relationships to adjacent MMA divisions and catchweight arrangements
- Unresolved eligibility questions and recorded official determinations
Out of scope
- Heavyweight classifications in boxing, wrestling, and other sports
- Athlete biographies, medical fitness, and weight-management advice
- Complete MMA competition and officiating rules
- Individual bout execution, scoring, and results
- Championship ownership and ranking calculations
- Heavyweight as a metaphor for influence or importance
Why it exists Filled
Enable an agent to identify the heavyweight division in mixed martial arts, assess weight-class eligibility under a specified ruleset, and identify decisions requiring an official ruling.
Distinguishing features Filled
- The classification must explicitly concern mixed martial arts rather than another sport using the same name.
- The referent is a division, not an athlete described as a heavyweight or a championship carrying that label.
- Eligibility must be evaluated against identified weight boundaries rather than appearance or ordinary body mass.
- A shared heavyweight label does not establish equivalent boundaries across authorities or historical periods.
- A negotiated bout weight does not by itself establish that the contest belongs to the heavyweight division.
What robots and AI may and may not do Filled
Must not
- Present one body's heavyweight limit as applying to all sports or organizations.

Only with a human decision
- Declaring a fighter eligible or ineligible after a disputed weigh-in.
May
- Explain the heavyweight limits under a named sport's ruleset and governing body.
- Report heavyweight champions and results from official records with dates.
Moral aspects Filled
- Heavyweight bouts carry large forces and serious risk of brain injury.

Open questions
- Which primary rule publications establish the heavyweight limits and endpoint conventions for the authorities this catalogue needs to cover?
- Which title, non-title, amateur, or other competition conditions alter heavyweight allowances or eligibility procedures?

- Does an existing Vercy world model already own MMA heavyweight, requiring this registry entry to link to it rather than receive a separate publication?
