Platforms change rules; revenue shouldn’t wobble. Today’s deep dive turns distribution into a moat: map owned vs. rented vs. borrowed channels, build a one-page “Distribution OS” (revenue mix, CAC/payback, renewal & price integrity, platform-risk ratings), install tiered offers to prevent channel conflict, write real partner P&Ls, and keep a live contingency runbook for TikTok-style policy shocks. Includes a 14-day plan to shift spend to owned routes, harden partner lanes, and re-route demand the same day a platform flips.
