Why private model work starts with data movement, runtime location, and access paths.

Model choice should follow the deployment boundary.
A model that looks strong in isolation may be wrong for the actual system if it cannot run where the workflow needs to live, cannot use the permitted data path, or cannot be handed over to the customer team in a maintainable way.
Before evaluating models, define the operating shape:
The boundary is not paperwork. It is part of the technical design.
Define what material can be copied, transformed, cached, exported, or kept local.
Define where the model and supporting workflow can actually run.
Define who can operate the workflow and through which surface.
Define the practical operating limits before choosing the model.
Define what must remain understandable after implementation.
The boundary can change the model decision more than a benchmark result.
A model may be technically attractive but unsuitable if it pushes the environment beyond its operating limits, requires a data path the customer cannot use, or creates handoff complexity the team cannot maintain.
Boundary decisions affect:
Choose from the models that can live inside the boundary. Do not define the boundary after choosing the model.
If these answers are unclear, the model shortlist is premature.
Define the deployment environment, data movement limits, access path, resource ceiling, and handoff expectations.
Shortlist models, adapters, runtimes, and quantization choices that can fit inside that boundary.
Test the candidate path against task examples, known-limit cases, latency expectations, and review criteria.
This keeps model work tied to an environment that can actually be operated.
Do not start with "the best model."
Start with the deployment boundary:
Then choose the model path that can run, be reviewed, and be maintained inside that shape.
