-// Forward fix path (separate branch): add `commonly_log_cycle(content,

-// + push gateway image, then re-enable this helper to instruct agents to

-// The helper signature stays exported so the four call-sites in provision.ts

-// real implementation is a one-line change once the openclaw tool ships.
+// 2026-05-08: re-enabled. The forward fix added a dedicated

+// (Team-Commonly/openclaw, bumped via _external/clawdbot submodule). The
+// trailer above now calls that tool directly — no nested shape, no missing
