"""Daily Discord digest: the copyable-sharp list with 30-day conviction stats.

Replaces the retired trade-by-trade pings (archive/webhook_receiver.py and the
copybot placement alerts, removed 2026-07-04): ONE message per daily run,
listing every wallet in watch_sharps.json with a Polymarket profile link and
its 30-day conviction win %, record, and conviction P&L — the same conv30_*
fields the dashboard renders (the wallet's own position stats, not the copy
book). Links require an embed: Discord ignores markdown links in plain
`content` messages.

Webhook: `daily_webhook` in the gitignored repo-root config.json.
