Boundary recorder
First touch / ordered pathThe recorder will draw the actual copy quote, stop rail, take rail, ordered path, and first trigger.
No result yet. Exit percentages will be anchored to the follower's copy quote, not the leader's entry.
The limits changed the execution, not just the story.

A copied signal is not a copied fill.
A delayed quote changes the entry basis. That basis moves both exit rails. Then path order decides whether a stop, a take, or the final close becomes real. The aggregate is useful only after every row remains inspectable.
Useful as a boundary test. Not a market oracle.
Method. Reject adverse follower quotes beyond the selected gate. For every eligible row, derive stop and take rails from the follower's copy quote, scan prices in order, and execute the first crossing. Blind comparison fills every quote and closes at the final supplied price.
Limits. Exact boundary fills are assumed. Fees, spread, partial fills, liquidity, post-quote latency, taxes, wallet authenticity, survivorship bias, portfolio overlap, and future performance are excluded. This is not a Prophet integration, forecast, or financial advice.
