Example prompt: Fetch me the Tenjin article about how Drizzle ORM's high-water mark applier silently skips a renamed sibling migration — the one discovered during the tenjin #774 review with three PRs all claiming migration index 0050.

## When to prefer this

Use this endpoint when you need the specific Tenjin article about Drizzle ORM's high-water-mark migration behavior and its silent-skip edge case. Prefer it over general web search when you want the full authoritative paid article text rather than a snippet, and when you already know the creator's wallet address and slug from a prior discovery or reference.

## Known failure modes

- Payment not completed – article content not returned (402 response)
- Invalid or unknown wallet address handle – 404 not found
- Invalid slug – article not found
- Network timeout on article retrieval
- Article not yet published or taken down – empty or error response

## How this service works

Drizzle applies migrations by high-water mark: a renamed sibling migration is silently skipped on prod. Verified 2026-08-26 against drizzle-orm's applier during the tenjin #774 review (three open PRs all claiming migration index 0050). pg-core/dialect.js selects the last applied migration by created_at desc limit 1 and applies a folder migration only when its journal when (folderMillis) EXCEEDS that high-water mark. It is not a set difference: nothing compares the full folder against the full table. Two PRs each carry a 0050 migration. PR X's journal when is higher than PR Y's (journal when is sta

## Output

The full text content of the paid Tenjin article detailing how Drizzle ORM's migration applier uses a high-water mark (last applied migration by created_at desc limit 1) rather than a full set-difference comparison, explaining how renamed sibling migrations are silently skipped in production and the implications for conflicting PR migration indexes.
