Form

A photograph may suggest geometry, a capture set may support reconstruction, and an existing mesh may need a new material, rig, or block projection. Form carries each requested operation to a validated spatial result with its sources, representation, scale, and loss still visible.

Choose the operation first, then inspect the facets it must return. A useful preview cannot settle those technical questions. Creative adoption, engine import, animation, and live-world placement remain with the consuming owner.

This candidate study was reviewed on 2026-08-08. The contracts and bakes below are Designed; State records the present visual boundary.

One form job, explicit operation

There is no mature universal OpenAI-compatible 3D serving protocol to make the inner contract. The candidate FormJob@2 names one explicit operation while its selected profile declares the inputs, output facets, controls, and limits it has actually proved:

The job carries immutable input and control ArtifactRef values; original and derived prompts; requested operation and output facets; units, axes, origin, scale, bounds, coordinate transforms, seed policy, immutable preset, deadline, budget, and a closed engine-extension object. Optional material never invents support. Text-to-image-to-form is a legitimate compound route, but the generated image remains an attributable intermediate artifact rather than hidden prompt machinery.

Sight may supply masks, regions, pose, depth, flow, and camera estimates as exact input facets. Form owns reconstruction and form generation; monocular relative depth is neither metric geometry nor a reconstructed mesh.

FormJob@2 owns spatial stages, candidate facets, technical validation, and result settlement. Creative adoption and engine use belong to their consuming Compositions. Each concrete service or tool execution uses Core's Designed ServiceJobAttempt@1 state, idempotency, cancellation, reconciliation, and indeterminate-effect law. The parent Run remains nonterminal and fenced while the same attempt is indeterminate; neither job nor effect is replayed under a new identity.

Progress, cancellation, and return

Stages such as camera solve, generating or reconstructing, extracting, texturing, rigging, baking, validating, and exporting are reported separately from numeric progress. Cancellation before GPU admission, cooperative model cancellation, bounded worker termination, and tool-process termination are different proved capabilities. A vanished worker does not prove that its effect stopped or failed.

Partial, temporary, failed, or uncertain output enters quarantined Reliquary custody with its own digest and working-set relation so restart and reconciliation can inspect it. Only validated output enters the settled Prism Form result. Reconnect reconciles the exact provider job, request digest, working-set receipt, and returned artifacts; it never blindly retries an uncertain paid or remote effect.

Every canonical receipt retains request digest and idempotency key; input, intermediate, and output digests; model weights, runtime, container, graph, tool, add-on, and dependency revisions and licenses; seed and exact configuration; dtype, quantization, offload and device topology; units, axes, scale, transforms, camera uncertainty, and representation facts; timing, peak resources, warnings, validation, cancellation settlement, and declared conversion loss. Provider paths, Python objects, and embedded file metadata are evidence inputs, not canonical provenance.

One asset set, typed facets

"3D" is not one flat output enum. FormAssetSet@1 groups separately typed facets whose relations remain explicit:

Canonical handoff normally uses a GLB/glTF container that may combine mesh, PBR appearance, deformation, and animation facets when each is present. A Gaussian PLY or exact renderer package, a NeRF checkpoint and configuration, and their camera sets remain field/render facets. They do not impersonate point clouds or meshes merely because a viewer can render each of them.

Every conversion is a new derivative. Meshing a radiance field, baking a Gaussian scene, reducing a textured mesh to blocks, retopologizing geometry, or converting a rig may discard information; the receipt names that loss. Reconstruction remains inferred from admitted captures. Metric scale is claimed only when camera calibration or an admitted scale reference supports it. TRELLIS.2's internal sparse voxel representation is not a Minecraft block grid and receives no shortcut around explicit conversion.

Hostile form custody

The Reliquary owns every source before Form materializes it. Admission bounds external URIs, archive expansion, vertices, faces, nodes, scene depth, materials, texture pixels and channels, animation channels, bones and influences, points, splats, voxels, training frames, parser memory, GPU time, disk, and output expansion. Importers verify claimed media types and reject recursive or unsupported content.

Scripts, drivers, expressions, add-ons, custom nodes, linked libraries, remote references, and generated procedures remain inert unless a separate contained tool effect explicitly admits them. Blender and ComfyUI workers run rootlessly without ambient home access, network access, auto-run scripts, arbitrary plug-ins or nodes, and runtime downloads. A capture set additionally retains consent, camera facts, and every source frame; rendering another view cannot launder the people, places, or restricted material it depicts.

Composition boundaries

Prism owns hostile-form handling, technical dispatch, transforms, facet semantics, conformance to the declared Form profile, and effect provenance. An independent validator checks tool output where the transforming tool cannot establish its own result. Atelier owns creative acceptance, the brief, candidate review, accepted form asset, and visual package. Foundry owns target-engine import and validation, coordinate and material adaptation, collision, LOD, performance, engine-native scene assembly, and playability. Blockworld owns live-world effect validation and bounded missions. A Form output crossing any boundary is an exact artifact handoff, never shared authority.

An Avatar profile may reference an exact Form asset, rig, and morph ontology. Form still owns only that spatial material and its provenance; it does not bind Persona, open an Avatar presence, admit a Spectre VR Habitat or Encounter, drive the projection, or acquire world or body authority.

Model workers, graph serving, and tool workers

The first implementation should expose one Prism-owned Form semantic interface and several immutable profiles instead of promoting each research repository into Core protocol. A resident, queued, or remote model worker is an Animator reached through a JobGrant; a finite model or tool execution is selected by the Spell Resolution Lock and delivered into a trusted executor or Tomb. A pinned contained process is not a fake Soulstone. Neither path is interchangeable merely because both can emit GLB.

OpenAI Images, OpenAI Videos, ordinary vLLM, and vLLM-Omni are not silently extended into 3D. They may produce conditioning images or video through their own contracts, but Form owns the job, facet semantics, custody, and recovery. Diffusers or a repository's Python demo is a model integration substrate, not a durable multi-user job service by itself.

A Form graph must use only the preset and parameter openings admitted under the ComfyUI engine contract. Unapproved runtime downloads or remote nodes cannot fill gaps in a local profile.

First model profiles

No current open stack reliably turns an arbitrary prompt or video into a finished, rigged, PBR, engine-ready scene. The initial register deliberately composes narrower champions:

Stable Fast 3D remains a useful fast challenger, but its Community License, registration, attribution, and revenue conditions keep it outside the permissive default. Hunyuan3D 2.1 remains a technical reference, not an eligible Bratislava deployment: its published community license does not grant use in the European Union, United Kingdom, or South Korea. Eligibility is re-evaluated from the pinned license before download and execution; neither a model wrapper nor a community quantization repairs a withheld grant.

DreamCubed is an interesting Minecraft-native research candidate for chunk generation, biome conditioning, inpainting, supersampling, and stitching. The official DP4 and DP2 Hugging Face cards label those exact weights Apache-2.0, while CP2 currently surfaces neither model-card text nor a license file. The two-commit code repository likewise exposes no license file, and the dataset, block mappings, textures, dependencies, and resulting-use terms are not closed. The whole route therefore remains license-blocked research rather than a Core profile. Even after closure, model tokens must map to the canonical block palette and pass the same validation and consumer admission as any other block source.

The first text-to-form quality route is text-to-image through Image, then the admitted image-to-PBR TRELLIS.2 profile. Both effects, both prompts, and the intermediate image remain in lineage. A candidate editable-character chain may retain the original unified shape, derive optional semantic parts, select compatible geometry for rigging, then perform contained Blender validation. Every handoff needs its own compatibility bake: disconnected part meshes or seams may invalidate skinning and cannot be assumed to compose with SkinTokens or UniRig. Form hands the exact skeleton, hierarchy, rest and bind transforms, local frames, axes, units, limits, skinning, and morph ontology to Kinesis. Kinesis owns motion clips and technical retargeting; Atelier owns animated storytelling. Neither is an implied feature of rig.

Profiles, Runes, Covens, and arbitrary iron

Use Prism's admission route to obtain the exact model and deployment binding. Separate consumer-GPU workers, a resident workstation profile, an Orchestrator transition after affected leases drain, or an explicitly admitted Portal each needs its own measured evidence. Two GPUs do not automatically pool VRAM; a published minimum does not prove an unmeasured driver, precision, resolution, or offload topology.

The proving bake

The proving corpus covers single images, multiview references, transparent and ambiguous objects, thin structures, open and non-manifold meshes, hard-surface and organic forms, PBR channels, semantic parts, humanoid and non-humanoid rigs, camera reconstruction with missing coverage, Gaussian and radiance portability, Slovak and multilingual briefs, adversarial files, cancellation, OOM, restart, stasis, and deterministic replay where claimed. Voxel fixtures cover exact 32-cubed bounds, solid, shell, and surface policies, palette collisions, clipping, empty and full volumes, block inpainting, closed procedural recipes, .schem round trip, and prohibited stateful blocks.

Measure conditioning adherence, multiview consistency, geometry completeness, topology and manifoldness where required, normals, UV and PBR validity, texture seams and projection error, scale and axis correctness, part usefulness, skeleton hierarchy, skin-weight normalization and deformation clips, held-out reconstruction views, representation portability, voxel occupancy and silhouette error, palette validity, output validity, latency, peak VRAM and host RAM, disk use, cancellation settlement, recovery, lineage, and license closure. Promotion is per exact model, worker, dependency, tool, preset, precision, device topology, input class, and facet set. A prettier turntable cannot conceal an invalid asset or authority gap.

For the complete bounded grid, palette, schematic, and read-back workflow, follow Voxel and block export. Form retains the spatial request and result; the consuming application admits the exported artifact and any later world effect.
