On the workbench
Keep the decision.
Keep the why.
Invariant is a documented product concept for decision integrity and continuity. It is not a released app.
When context is part of the work.
A decision is more than its final sentence. There is the reason behind it, the constraints around it, and what was still unknown when it was made. Invariant is being designed to preserve those distinctions.
What the specification proposes.
- Separate ideas, drafts and final decisions.
- Preserve final records; record a replacement rather than silently rewriting history.
- Keep projects separate and uncertainty explicit.
- Support taking records out of the system rather than depending on permanent access.
What exists today.
Living core documents, an MVP interaction specification and brand research. The earlier working name KeepUpApps belongs to that development history. There is no public Invariant app, confirmed release date, pricing or waitlist.
These are design intentions. They are not claims that a live service already provides these capabilities.
