+name: Wiki Sync

+# Keeps the GitHub wiki in sync with docs/ on every release that lands on main.
+# The wiki has no native generator and historically drifts (it sat at "212+ providers /
+# 14 strategies / 37 MCP tools" while code was at 226 / 15 / 87, and new docs like
+# SUPPLY_CHAIN never appeared). This runs scripts/docs/sync-wiki.mjs, which:
+#   - ADDS any docs/ page missing from the wiki (curated; internal reports excluded),
+#   - syncs the four cover-page counts on Home.md.
+# It does NOT overwrite existing wiki pages by default: several docs sources still carry
+# stale counts (e.g. ARCHITECTURE.md says "177 providers" while the wiki cover is 226),
+# so blind overwrite would regress the wiki. Full content parity (--update-existing) is
+# gated on regenerating those sources first.
