- forin-keys.test.ts matches the record-ops table with its eighth field, the
store hook, which is null for a record no untyped code writes.
- bench/record-untyped-writes writes typed records through `unknown` and
`Object.assign` views, so it links dynamic-tier symbols; DYNAMIC_WORKLOADS
lists it.
- The sanitized self-hosting emission test gets a 600 s timeout. It takes
about half of the default 300 s on an idle 16-core host, with or without
these changes, and exceeded the default on a loaded CI shard.
