+# ── Fix 12: BTCPay Lightning route hints ─────────────────────
+# A BTCPay store whose LND node has only private (unannounced) channels
+# produces BOLT11 invoices that external wallets cannot route to unless the
+# store's lightningPrivateRouteHints flag is on — payers see "no way to pay
+# this invoice" (observed on shorty-s 2026-07-10 with a Blink payer). Route
+# hints are a no-op with public channels and essential with private ones, so
+# the doctor enforces the flag on every store. BTCPay reads store blobs from
+# Postgres per request; no restart needed.
