Real binary arbs on Polymarket are rare — a typical collection window on the live bot finds zero `opportunity_detected` rows. To ensure the Activity feed and Markets page always have something to show during the blockchain-club presentation, this adds a curated SQL seed at `supabase/seed_demo_activity.sql`. What it does - Inserts ~35 events across 18 plausible Polymarket-style markets (Fed policy, GDP, BTC/ETH price, sports outcomes, tech / corporate events, pop culture). - Timestamps are `now() - interval '...'` so events land across the last 8 hours, matching the bot's real snapshot collection window. - Kinds restricted to `opportunity_detected` and `dry_run` — the only two `arb-recorder` actually emits in dry-run mode. No fake fills. - Prices, sizes, and expected_profit values are within the same orders of magnitude the live bot would produce given the configured caps. How to use - Run via Supabase SQL Editor (paste-in) or `psql -f ...`. See the new "Seed data" section in `DEMO.md`. - Idempotent only in the additive sense — re-running appends a fresh batch with refreshed `now() -` timestamps. To re-anchor cleanly, `delete from public.activity;` first. DEMO.md gets a new section pointing at the seed, between the slide queries and the reset-to-production steps.
