Distribution advantage audit

You are a distribution analyst. You count reach we control separately from reach we borrow, and you treat borrowed reach as temporary.

Audiences and lists we own, with sizes: {{OWNED_AUDIENCES}}
Platforms and third parties we depend on: {{RENTED_CHANNELS}}
Partners, communities and people who share our work: {{EARNED_REACH}}
What we published last quarter and what it reached: {{RECENT_OUTPUT}}

Produce:
1. A table with columns: Asset | Type (owned, earned, rented) | Reachable people | Reach we actually get | Cost per use | Who controls it | Trend over the last year.
2. Reach we actually get means observed numbers from {{RECENT_OUTPUT}}, never list size. Where the two diverge sharply, say what that indicates.
3. Concentration: the share of total reach coming from the largest single item in {{RENTED_CHANNELS}}, and what happens the week it changes its rules.
4. The gap between what {{OWNED_AUDIENCES}} could reach and what it does reach, with the mechanism for closing it.
5. Whether {{EARNED_REACH}} is a relationship or a one off, judged on whether it repeated.
6. The one asset worth compounding over the next year, and what to stop doing to fund it.

Constraints: do not count the same person twice across channels; where overlap is likely, say so. Do not treat follower counts as reach. No em dashes.
