The Day One Letter does not gate the archive. Every issue, from the launch onward, stays free and indexable forever. The newsletter is not the lead funnel. The newsletter is the publication.
Issues are categorized at publication by primary topic. Where an issue covers a specific pricing benchmark, it sits under Pricing Benchmarks. Where it covers a tactical move at the table, it sits under Negotiation Tactics. The categorization is consistent across the volume so the archive remains searchable as it grows.
