SQLCommenter integration for Prisma ORM via driver adapter wrapping. Automatically appends query metadata (db_driver, route, method, file) as SQL comments to all Prisma queries. Key design decisions: - wrapAdapter patches the adapter in-place (not Object.create) to preserve Prisma's error registry object identity - wrapAdapterFactory supports Prisma 6+ SqlDriverAdapterFactory pattern where PrismaPg.connect() returns the SqlDriverAdapter - Bridges ALS context across Prisma's WASM engine boundary via module-level variables, since AsyncLocalStorage is lost when the Rust engine calls back into JS Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Prisma's PrismaPromise defers execution via .then(), so by the time $allOperations fires, the user code is no longer on the call stack. The first non-filtered frame was node:internal/process/task_queues, producing a misleading file tag. Filter node:internal and node:async_hooks frames so the file tag is omitted rather than wrong.

Full-stack Express + React demo showing Prisma 7's native `comments` API with `@prisma/sqlcommenter-query-tags`. Includes proxy-based call-site capture for the `file` tag (path:line:column) and `withQueryTags` middleware for route/method injection. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
