MDPE.15:4 - Solution

A capable Agent performs Work that enacts the applicable direct Method to make the selected local change. Observation Work obtains a bounded trial result. Use this pattern to prepare an account that distinguishes the objects and relations involved. The numbered subsections explain the MethodDescription; they are not a WorkPlan, and actual Work can follow a different order.

The load-bearing relations differ. The decision selecting the change must still apply; its authority and permission relations must obtain; and the needed capability, resources, and safety conditions must be present when change Work begins. That Work can produce a changed subject, a new variant, a partial change, or a failed attempt. Reidentification compares the starting and later subject. Trial Work can overlap change Work, follow it, or remain independent. An effect claim additionally needs a suitable comparison or causal Method; a result account relies only on the observations and relations actually obtained. Later cultural continuation remains a different question.

When the applicable Method contains branches, joins, returns, cycles, or several live continuations, represent that unfolding with A.22.CGUS; the traversal below is only one demonstrative slice. A causal graph used through C.29 represents causal claims or hypotheses; C.28 governs the evidence needed for their intended use. The graph does not command action. An acausal constraint model can preserve relations without choosing a calculation or action direction.

MDPE.15:4.1 - Admit one selected and still-feasible change

Identify:

• the decision source, selected option, DecisionSubject, and applicable direct authority relation;
• the practice-developing Agent that can perform the change Work, the declared A.2.1 assignment species and obtaining occurrence when assignment changes the decision, and the F.6 Work attribution when that Work occurs;
• permission, consent, safety, access, and resource conditions for the Work;
• the changed practice subject and its starting configuration;
• the intended direct result and present use;
• the direct change Method; and
• the smallest observation that could change the next decision.

Recheck these values immediately before Work. A choice, authority relation, permission, consent, capability claim, or resource commitment established for one subject and configuration does not extend automatically to different participants, a new venue, another robot edition, or a wider cultural intervention. If the selected change no longer satisfies these conditions, return to the DecisionSubject instead of silently revising the option during implementation.

MDPE.15:4.2 - State what will and will not change

Describe the target through its own kind and identity conditions. Useful subjects include:

• a named musical or movement-material entity;
• one Method or Method part whose identity continues through the change;
• a new Method variant related to, but not identical with, its source;
• one MethodDescription or performance description;
• a capability of one human, robot, AI, pair, ensemble, or hybrid holder;
• one instrument, body interface, software, robot, venue, or enabling configuration;
• one teaching, rehearsal, performance, event, curation, recognition, or selection arrangement; or
• one locally maintained repertoire member or branch.

State protected characteristics and boundaries. For a Dance change these may include weight transfer, partner-readable pressure, effort, balance, floorcraft, consent, rhythmic interpretation, style-bearing distinctions, and bodily variability. For a Music change they may include pitch, rhythm, pulse, timbre, articulation, breath, gesture, ensemble cueing, latency, performer control, and musical plausibility. Select only those that can change the present decision.

MDPE.15:4.3 - Prepare only the plan the Work needs

Use A.15.2 when a U.WorkPlan is needed. Keep it small enough to expose:

• the performing Agents, any decision-bearing A.2.1 assignments, and supporting non-agent Systems;
• the selected change and direct Method;
• required material, tools, venue, bodies, instruments, software, or data;
• safety, consent, access, stop, and rollback conditions;
• the relation between change Work and any trial or evaluation Work;
• the observations and evidence to retain; and
• the next decision that may use the result.

Use C.24 only when tool or call planning is current. A useful plan remains an episteme and never establishes that Work occurred.

MDPE.15:4.4 - Perform the change Work under the direct Method

Identify the dated U.Work occurrence, performing Agent, enacted Method, inputs, conditions, and direct outputs. The Agent performs Work that enacts the applicable domain Method—for example, composition, arrangement, choreography, translation, teaching, rehearsal, somatic practice, instrument setup, control, software development, event production, curation, or recognition-arrangement design—and that Work changes the identified subject.

If current facts change a live execution branch, A.15.7 can help choose one bounded next action under the already-admitted Method. It does not replace the prior change decision.

When the Work stops or only partly succeeds, preserve that result. Name the stopped condition, actual output, unchanged or partly changed subject, recoverable state, and next safe action.

MDPE.15:4.5 - Reidentify the subject after Work

Compare the starting and later conditions under A.3.4 or the direct governor of the change. Ask:

1. Did the intended subject actually change?
2. Does its identity continue, or did Work produce a new variant or artifact?
3. Which relation supports the claimed transformation?
4. Which characteristics changed, stayed within bounds, or became unknown?
5. Did another subject change instead—for example, only the description, tool setting, performer capability, or event arrangement?

Report the subject that actually changed. If the class plan changed but teaching Work did not, report the plan change. If the dancer enacted a phrase once but capability transfer was not tested, report the occurrence and observation. If software changed but the robot did not perform under the intended conditions, report the software result and missing trial.

MDPE.15:4.6 - Obtain a bounded trial and keep its Work separate

Choose trial conditions representative enough for the decision and safe enough for the current change. Identify:

• the tested subject and configuration;
• the performer and observer Systems;
• the trial or evaluation Method;
• obtaining relation to the changed subject;
• relevant environment, audience, partner, instrument, venue, tempo, media, or platform conditions;
• observations, uncertainty, and missing witnesses; and
• protected characteristics and stop conditions.

Change Work and trial Work may overlap—for example, a dancer adjusts a partnering cue during a supervised trial—or occur separately, as when an arrangement is edited and later rehearsed. State their temporal relation separately from any part–whole relation. A trial can be a constituent of larger change Work when its performance contributes to that encompassing work; explain the connection using B.1.5.EW. Overlap or succession alone does not establish it.

MDPE.15:4.7 - Separate direct result, observation, and effect

Return only the strongest supported statement.

Use practitioner judgement as evidence when the practitioner, question, basis, conditions, uncertainty, and update condition are visible. Do not replace direct use evidence with press attention, university publication, standard conformance, platform reach, or a technical score.

MDPE.15:4.8 - Return the local practice-change result account

Return a readable account containing:

Local Music-or-Dance practice-change result account:
  selected change and decision source:
  DecisionSubject, practice-developing Agent, authority, and permission:
  changed practice subject and starting configuration:
  direct change Method:
  performed change Work:
  changed subject, new variant, or failed attempt:
  direct result:
  separate trial or evaluation Work and its relation to change Work:
  bounded observations, affected Systems, and limits:
  supported effect, if any:
  protected characteristics, losses, and residual conflict:
  retained alternatives and rollback or source return:
  later-evidence question:
  next decision and reopen condition:

This optional writing aid describes the named objects and relations. The account records evidence about the attempted Work and any resulting change.

If the change cannot lawfully proceed, return an unavailable-change statement naming:

• the missing choice, authority, permission, capability, Method, resource, evidence, configuration, or relation;
• the change Work or development decision it prevents;
• any safe partial result already obtained; and
• an observable retry condition.

MDPE.15:4.9 - Keep the later cultural question open

One local change can supply a Method or repertoire input to MDPE.17, an observation to MDPE.12, a revision to MDPE.14, or evidence to MDPE.7. It does not establish that another practitioner can perform representative Work that enacts the Method, that a population recognizes or selects the variant, or that the variant is retained. State the smallest later question explicitly.

MDPE.15:4.10 - What Changes in Practice

Before this pattern, a project can show a new score, phrase, class, rule, tool, or technical result and say the practice improved. After it, the project can identify the decision, actual Work, changed subject or failed attempt, direct result, bounded trial evidence, moved burden, and the cultural claim that remains open. Failed and partial changes become reusable evidence instead of disappearing from the development story.
