Areas and loops.Gated on energisation.
Loop checks, flushing, energisation and trip tests, each holding the next stage closed until its threshold is met. Same engine, different words: areas instead of systems, loops instead of sub-systems.

Project management with a full audit trail for every item, in one place.
Cairn OS is for work that has to be proven, not just reported. A project is broken down into every individual item it contains. Each item carries the records that prove it reached each stage, and each record carries who signed it and when.
The engine holds no vocabulary of its own. You define what your levels, items, records and stages are called, and every screen, dashboard and export uses your words. That is how one system fits any project shape without being rebuilt for it, and how progress, sign-off and traceability end up in one place rather than three.
- Item
- The smallest thing you track. You decide what it is and what it is called.
- Record
- The form that proves an item reached a stage. You define its fields and its rules.
- Stage
- How far along an item is. You define the sequence, and what each stage holds shut.
- Roll-up
- Completion added up from single items to the whole project, recomputed as records are signed.
- Audit trail
- Every record, signature and revision, kept immutably and queryable.
Column positions never move. Only what the headers say.
That is the whole argument. Change the vocabulary and every screen, dashboard and export follows, because the shape of the data never depended on the words in the first place.
