A brand built to move needs a way to know when it has gone too far.

Two stories should not be collapsed. Stack launched on 3 June as an AI accounting platform, and Paul Jun's 21 August post names the evolving parent system Solar System, reporting a four-week first version. In Offgrid's Stack work, a dark wordmark and layered symbol sit on cream and citron, with folded planes making the idea of a stack tangible.

Coherence is harder than sameness because it needs judgement. If every output can differ, the system has to say which differences matter, and a team has to be able to reject work that uses the right colour and still feels wrong. Ramp reports serving more than 4,500 accounting firms, including 92 of the largest 100. That is company-reported context, not proof of identity performance.

The lower Memory rating reflects uncertainty about continuity under extension, not a failed test. A generator can make thousands of outputs while leaving the same few decisions unresolved.
