Keyset-paginated delta feed of fund-letter events (letter.published, letter.updated, letter.superseded, thesis.extracted, manager.added). Never response-cached.

Audience: application and coding agent.

Coverage and source scope

Metered as fund_letter_lookup. The cursor is an opaque keyset token minted by this endpoint (never an offset); malformed cursors 400 as invalid_cursor. nextCursor pins the last returned row whenever the page is non-empty, so pollers resume from it regardless of hasMore.
