AIRA
Project memory and facts
What AIRA remembers between runs, how facts are established, and how to correct something it has wrong.
AIRA keeps a memory of what has been established about a project, so a fact you correct once stays corrected across later runs. Without it, every re-run would relitigate the same assumptions.
Where facts come from
Every fact carries its provenance — whether it came from a document you uploaded, from something you typed, from the site boundary, or from AIRA's own inference. The interface distinguishes them, and the distinction matters: an inferred figure is a reasonable guess standing in for a real number until someone supplies one.
Correcting a fact
Edit it where it is shown. A corrected fact supersedes the old one and is used by every subsequent run.
Pinned facts are never superseded
A fact you pin stays authoritative — later generation cannot overwrite it. That is exactly what you want for a surveyed site area or a statutory limit, and exactly what you do not want for a placeholder you pinned by accident. Unpin it if the project moves on.
Reviewing what it believes
The memory panel lists what AIRA currently holds about the project. It is worth reading once before a big re-run — an assumption that was fine three weeks ago may not have survived a change in the brief.
