Shared Boundary is the Imprint earned from the side story of Aster and Vessa, The Border of an Agreement. It gives you more warning of what you can already see.
How it works#
- Front and border telegraphs that are already visible appear one round earlier.
- It never reveals a hidden threat. Only Survey does that.
- You have one less move in the first round of each room.
- The story completes at step AV4, "Something worth agreeing on".
Numbers#
Claude B's bots read the true room state, so they feel the cost and never the benefit. That is why it sits near 10% in their pick rates, tied with no Imprint. Claude B marks this as "not measured", never as "weak".
Development#
It replaced the old "watch" keepsake, an active short Survey lent for one outing. The user approved the name on 31 October. The turn effect (extraLead) was built on 2 November and is in the alpha engine; the presenter draws the earlier telegraphs. The side story needs Act II scenes (II2, II5, II6) that the alpha does not yet stage.
