The board-shaped view of the same truth.
Portae is the perspective where project truth becomes something a human can work with directly. Requirements, architecture decisions, tests, defects, dispatch messages, implementation evidence, and review comments are not scattered across separate tools. They become typed Cards with stable identity, links, status, and history.
That shape matters because AI-era work moves quickly. A requirement can produce architecture, an architecture decision can open assignments, a defect can require a test, and an agent response can become evidence. Portae keeps those movements inspectable instead of letting them dissolve into tickets, chat fragments, and private memory.
Portae is not just requirements management. It is the board view of the model: what the work is, who is touching it, and why the next step is justified.
This is also why Portae and Meaning Graphs belong together. Portae can hold the requirement, decision, assignment, and review context; Meaning Graphs can show how the code and UML evidence support that context. They are two perspectives over one Library, not two competing systems.
