"AI can generate code fast, but without context, boundaries, and language, you get coupling and brittle systems."
Context Is the Bottleneck in Software Development - CodeOpinion
Software development context matters more than ever. AI can write code, but it can’t guess intent, tradeoffs, or boundaries.

Assuming there is only one administrator may seem safe but there are many ramifications to the assumptions.
Fallacy #6: There is one administrator
In small networks, it is sometimes possible to have one administrator. This is usually the developer who creates and deploys a small project. As a result, this developer has all of the information…

Within a Unit of Work, there should be exactly one in-memory object per database identity.
Enterprise Patterns for ASP.NET Core Minimal API: Identity Map Pattern - Chris Woody Woodruff | Fractional Architect
If one customer quietly turns into three different in-memory objects during a single request, your domain is already lying to you. You see it when: Different parts of a request each load the same row again One instance is updated, another is validated, and a third is saved Bugs show up as “lost updates” or
