+-- Migration 0006: tip-recipient on policy.
+--
+-- Lets the operator configure a Lightning recipient + percentage on each
+-- policy. When a license issued under that policy settles, the daemon
+-- tries to send a Lightning tip of (license_price_sats * tip_pct_bps / 10000)
+-- to tip_recipient via the operator's BTCPay Lightning node.
+--
+-- All three fields are nullable / zero-default. Existing policies are
+-- unaffected: with NULL recipient the issuance hook is a no-op.
+--
+-- Recipient can be a Lightning Address (e.g. tip@keysat.xyz). LNURL-pay
+-- support may be added later; the current implementation resolves only
+-- Lightning Addresses via the .well-known/lnurlp/<user> endpoint.
