+// NOT an import.meta.url comparison (tried realpathSync AND plain
+// path.resolve, both wrong for the same reason): tsup's ESM output code-
+// splits this file's top-level statements into a SHARED CHUNK
+// (dist/chunk-*.js), so import.meta.url here resolves to that chunk's own
+// URL, not to push-schema.js's -- confirmed with debug logging, which
+// showed import.meta.url pointing at the chunk file on BOTH the direct
+// `node push-schema.js` invocation and run-migrations.js's import, with
+// process.argv[1] correctly showing 'push-schema.js' each time. Any
+// import.meta.url-based "am I the entry point" check is fundamentally
+// unreliable once a bundler is free to move module code into a shared
+// chunk. Checking argv[1]'s own filename instead sidesteps chunking
+// entirely -- it only asks what script node was told to run, never where
+// the executing code happens to live.
+//
+// WHY THIS MATTERS: run-migrations.ts imports and calls pushSchema()
+// directly (migration-runner.ts), so it never depended on this guard and
+// always worked. permission-smoke.integration.spec.ts's beforeAll runs
+// `node packages/database/dist/push-schema.js` standalone a second time in
+// the same CI job (to prove role_permissions grants survive a re-run
+// against already-seeded data) -- with the guard false, main() was never
+// called, so nothing ran: no thrown error, no output, exit code 0, and
+// integration_service came back with zero grants.
