Rubik's Cube

Baseline compatibility

Record the observed face layout and move structure before applying conventional 3×3×3 assumptions.

1. Does each face have a 3×3 facelet layout, and which layers can turn? definition
2. Which observed features require variant-specific rules instead of the baseline? boundary

Medium and attribution

Record whether the subject is a physical puzzle, executable simulation or depiction, and the evidence for any product identity.

1. Can this subject actually perform puzzle turns, or does it only depict a configuration? boundary
2. What markings, packaging or provider records support identifying it as a Rubik's Cube product? provenance

Stable face labelling

Record how observations map to puzzle-relative faces throughout inspection and manipulation.

1. Which observed faces establish the current up, front and right reference directions? definition
2. After the cube or camera rotates, how will the agent preserve the identity of previously observed faces? action

Observed piece configuration

Record inferred centre, edge and corner identities, positions and orientations without silently filling unseen facelets.

1. Which piece positions and orientations are established by the observations, and which remain ambiguous? measurement
2. Which additional face views would distinguish the remaining candidate configurations? action

State consistency assessment

Keep inventory checks separate from the stronger claim that a configuration can be reached by permitted turns.

1. Do the observed markings and reconstructed pieces match the declared puzzle inventory? measurement
2. What validated checks establish reachability for this variant, and which checks have actually been applied? provenance
3. If a check fails, what inspection can distinguish misreading from altered assembly or markings? action

Explicit target predicate

Record which arrangements count as complete, including any picture orientation or display orientation requirement.

1. Does completion require uniform faces, aligned pictures or symbols, or a specified target pattern? definition
2. Are whole-cube rotations equivalent for this goal, or must the result face a specified direction? boundary

Unambiguous turn instructions

Specify the moved layer, angle and viewing convention, and distinguish a face turn from reorienting the whole cube.

1. Which notation and viewing convention define each turn's layer and direction? definition
2. Which face, slice, wide or whole-cube moves are supported by this puzzle and executor? boundary

Plan preconditions and objective

Record the starting-state assumptions, target and optimisation criterion behind a proposed sequence.

1. Which configuration and reference frame must hold before this sequence begins? definition
2. Should the sequence prioritise a declared move-count metric, execution reliability, speed or teachability? action
3. What simulation or derivation supports the claim that this sequence reaches the target? provenance

Verified turn completion

Record whether a requested turn completed, stopped partway or affected a different layer.

1. Are the relevant layers aligned and unobstructed, or does the simulation interface accept the intended move? measurement
2. What observation confirms that the intended layer moved through the intended angle? measurement
3. How should the agent stop, reobserve and update its configuration after a missed or unexpected turn? action

Intervention boundary

Record resets, disassembly, piece reorientation or relabelling as interventions that require a new state assessment.

1. Which proposed actions alter assembly, markings or stored state instead of applying a permitted puzzle turn? boundary
2. Which interventions does the task authorise, and what observations must be repeated afterward? action
