Cross-venue divergence
Same event, two prices. We buy the cheap one — on paper: no Polymarket execution lane exists (and US-person access besides), and the linked universe is currently ~62 markets, growing with curation.
Harness live — no qualifying divergences yet (fee-netted edge on an approved same-event pair with two real books). Fills appear as they open; nothing is simulated retroactively.
How this loses
Failure mode: Resolution-criteria mismatch between venues, and legs that won't fill together. This card is a credibility exhibit, not a future live lane. A mismatch shows up below as a BROKEN fill with its realized loss.
Worst month: Worst month: a linked pair resolves on mismatched criteria — one leg loses in full while the hedge pays nothing.
