Keep coincident emblem components separately indexed

Preserve the authored roles of the emblem pieces

A fictional exhibition identity uses two angular decorative pieces as one emblem. The first represents the making stage and the second the finished collection. They meet in the approved pose, but the art director intends to commission different color treatments for their separate roles. A proposed export simplifies the authoring structure without recording that intention. The producer needs a more precise delivery brief before accepting the shortcut.

Name the two pieces in the content plan. Call them Making and Collection rather than relying on whatever object names happen to survive export. Record which campaign treatments belong to each role and who approves their use. This is an editorial distinction: the emblem can remain a recognizable whole while its parts have different responsibilities in future versions.

The immediate deliverable is an index ledger attached to that brief, not a recolored render. The team should not promise a particular appearance merely because the ledger is clear. It also should not erase the separate roles because the current promotional image happens to use the same color for both. The future variation is part of the requested authored asset, even when a single still image does not reveal it.

Arbitrary layout units: O = (0, 0, 0), A = (1, 0, 0), B = (0, 1, 0), C = (0, 0, 1), D = (−1, 0, 0), E = (0, −1, 0), F = (0, 0, −1). Oriented faces: (O, B, A), (O, A, C), (O, C, B), (A, B, C); (O, D, E), (O, F, D), (O, E, F), (D, F, E). Every edge has two incident faces, but O’s link has disconnected cycles A–B–C–A and D–E–F–D. Replace O by O1 in the first four faces and O2 in the last four, both at (0, 0, 0). Each resulting vertex link is one cycle. These are separate combinatorial sheets, still touching geometrically; no solid or printability claim follows.

The fixture was checked by local combinatorial code, not by CGAL or a renderer. It describes an invented asset rather than a scanned product. No physical object has been tested or certified.

Keep the numerical exhibit together rather than sending a screenshot of an isolated result. The recipient should be able to reconstruct the supplied candidate and the specified replacement from the same record. No part of this exercise authorizes a change to a live model, shared asset library or production setting.

Use neutral names in the technical exhibit and attach the authored role names in the accompanying brief. This keeps the mathematics inspectable without asking the implementation owner to guess which decorative element carries which story. A later artist can then discuss a revised treatment in ordinary design language while referring to the same clearly identified source material.

Choose a structured handoff instead of an unexplained shortcut

The first delivery option treats the current promotional image as the whole requirement. It supplies a compact asset and leaves future producers to infer how the emblem was meant to vary. That may be sufficient for a single fixed illustration, but it is not the authored handoff requested by this exhibition team. Its convenience depends on ignoring a planned use rather than resolving it.

The second option retains the two named creative roles and includes the replacement ledger from the exhibit. Choose this option for the stipulated brief. It gives the receiving artist a clear account of what the team wants to preserve. The cost is a more explicit handoff, with role descriptions and version relationships to maintain instead of a single unexplained file.

For the next campaign, suppose the making story should use a workshop palette while the collection story retains the exhibition palette. The brief should identify that intended distinction without pretending that the present exercise has rendered or accepted it. Material assignment and receiving behavior remain questions for the actual production workflow. A documented intention is useful even though it does not prove that every destination application will honor it.

Do not resolve the handoff by moving the pieces apart simply to make their roles easier to name. Their meeting pose belongs to the approved composition. If the art director wants a separated pose, that is a different creative option and should be considered as such. The current choice preserves the composition while making the requested authored relationship explicit.

Make future variations traceable

Prepare a packet containing the approved emblem pose, the two role descriptions, the complete numerical exhibit and the selected delivery approach. Keep the old shortcut identifiable as the superseded candidate. A later producer should be able to explain why the replacement was requested without assuming the earlier image was visually wrong.

When a real derivative is eventually produced, review it against the specific creative request and the supported delivery environment. This exercise has not performed that review. Keep an approved picture and an editable source distinct in the packet so a recipient cannot mistake the numerical illustration for evidence of a tested export.

The final outcome is an explicit authored-component handoff rather than an automatic cleanup claim. It preserves the two narrative roles, leaves the approved composition intact and identifies the selected replacement precisely. That is enough to guide the next production conversation without claiming a new appearance, a repaired physical object or a universally valid asset.

Make the reasoning concrete.

The exhibition plans to vary its Making and Collection treatments while keeping the approved emblem pose.

Choose the explicit handoff without claiming that a new derivative has been rendered.

Take the questions into your next brief.

Use these prompts in your own notes. Nothing is submitted from this page.

1. Roles

   What does each named piece contribute to the identity?

2. Variation

   Which future treatment requires those roles to remain explicit?

3. Witness

   Can the complete supplied candidate and replacement be reconstructed?

4. Pose

   Which approved composition remains unchanged?

5. Handoff

   What actual receiving evidence is still missing?

Watch for the wrong conclusion.

• Treating the current palette as the complete reuse brief.
• Renaming parts only by their temporary position or color.
• Presenting a documented intention as a tested export.
