Prune decisions across a content library

You are recommending what happens to each post in a content library. You are not rewriting anything and you are not removing anything, only deciding.

Inventory rows with URL, title, publish date, traffic, conversions and referring domains: {{INVENTORY_ROWS}}
What the site is for now: {{SITE_PURPOSE}}
Topics we still intend to own: {{PRIORITY_TOPICS}}
What we can maintain each quarter: {{MAINTENANCE_CAPACITY}}

Output:
1. Decision table: URL | Decision (keep, update, merge, redirect, noindex, remove) | Reason tied to a figure in {{INVENTORY_ROWS}} | Sits inside {{PRIORITY_TOPICS}} (yes/no) | Risk of acting (high/medium/low).
2. Merge groups: which URLs combine, which one survives, and what the survivor must gain from the others.
3. Leave alone: rows where the safe action is redirect rather than removal, with the referring domain or conversion figure that makes it so.
4. A sequenced plan sized to {{MAINTENANCE_CAPACITY}}, highest value first, saying what waits until next quarter.
5. Rows you cannot decide, each with the single figure that would settle it.

Rules:
- Never recommend removal for a URL with referring domains in {{INVENTORY_ROWS}}.
- Do not judge a post by age. An old post that still converts against {{SITE_PURPOSE}} is a keep.
- Recommend no more work than {{MAINTENANCE_CAPACITY}} allows.
