leTAIN / two lines / set before the outcome
A template for you and your collaborator.
One slider sets the code boundary. One sets the collaboration boundary. Move both, then read what the combined position asks of each of you.
Permit use under written terms while the contribution keeps its value.
The participant with reach can distribute without erasing the original contribution.
Contribution, attribution, threshold, calculation, and payment trigger must be agreed first.
Test the handoff before either side promises a larger build.
The record layer captures the agreed material; the witness layer verifies the frozen result; both participants inspect what worked.
The test proves only that handoff. It does not settle ownership, a long-term role, or a larger partnership.
Neither slider chooses for anyone. It shows the consequences of the two lines together.
Run one narrow test under a written contribution license. The code can move for the agreed purpose, but the trial does not erase ownership, attribution, or value—and it does not promise a larger partnership.
A checkable handoff without giving away more than the test requires.
Yes to the defined test and the rights written for it.
No implied public grant and no automatic long-term partnership.
You and your collaborator review the result before moving either line.
The Showcase rule: move close enough to enable the work without going over anyone’s boundary. If success later crosses a pre-agreed threshold, the contribution’s pre-agreed value is triggered—not renegotiated after the outcome.
