Every project has an original.
Almost nobody can find it.
The intent behind a building exists once — in the RFP, the proposal, the kickoff call. After that it survives only in copies: emails, redlines, submittals, change orders. Polygnotos keeps those copies linked, so the original is still recoverable at closeout.

What that looks like in practice
One design change, followed all the way through: the scoped plan, the evidence chain behind it, the agent reconstructing it on demand, and the invoice it became — captured from a seeded local instance, never from a live client project. Scroll to walk the chain.
What Polygnotos is
Polygnotos is project-management software for construction and engineering teams. It connects proposals, project communications, decisions, drawings, task orders, time, billing, and closeout so the record behind the work remains available.

Where this goes
The name
Polygnotos of Thasos was the great monumental painter of the early Classical period. Nothing he painted survives. His Iliupersis and Nekyia, made for the Lesche of the Knidians at Delphi, are known chiefly from Pausanias, writing roughly six centuries later — long, unusually particular about where each figure stood, and still only words.
Mark Stansbury-O’Donnell reconstructed both from that account, reading Pausanias literally enough — down to his prepositions — to recover compositions that the drawings reproduced for a century after Carl Robert had drifted away from. Paintings no living person has seen, rebuilt from the one surviving description of them.
That is the same problem a construction project has. Nobody holds the original intent. It survives in scattered, partial, sometimes contradictory copies, and the job is to reconstruct it faithfully from them — and to be honest about how confident you are.
The name is also carried by an Athenian vase-painter, and by the group of hands gathered under it in the Beazley Archive. That archive is the subject of polygnotos.org, a research workbench for Greek vase-painting, and the reason this platform has the name it does.
