This is a heap dump filename with a specific PID, meaning a heap dump was taken during development. Confirm the dump file itself is not tracked in the repository (git ls-files | grep hprof). The gitignore entry should use a wildcard (*.hprof) to catch any future dump rather than a single named file.

The token is set to a random UUID, persisted, then immediately overwritten with the real JWT and persisted again. This is two DB writes and leaves a window where the entity carries a meaningless token. Generate the ID first, build the JWT, set it once, then persist.

Non-expiring tokens are a security liability. If a bot token is leaked there is no recovery short of deleting the account. At minimum use a multi-year expiry, and surface a token-rotation endpoint so operators have a recovery path.
