oban-bg/oban: technical due diligence, read from its repository

The median source file here is 88 lines. 1 file exceed 1,000 lines, the largest being 1,799. Size is not a defect on its own — some problems genuinely live in one place — but these are where merge conflicts, review fatigue and single-owner knowledge concentrate, and they are the first thing that slows an inheriting engineer down.

2 of 44 locked dependencies match 7 published advisories in OSV. A lockfile says which version is installed, not whether the flawed code is reachable from this product, so each needs a look. Most are fixed by an upgrade, and the advisory names the version. This lockfile pins development tools alongside what ships and does not say which is which, so some of these may never reach a user.

The newest was published on 2026-05-26. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. Whether 2 of them are fixed in the code you ship could not be told from this history: its version is only known to be at least 2.24.1. Answer lives in: the release you run, set against each fixed version. The record is incomplete: NVD: 1 record names oban with nothing tying it to this repository (CVE-2026-78038).

Nothing in the service initialises an error reporter (Sentry, Rollbar, Bugsnag, Honeybadger or an APM agent). An exception in production reaches a person only if someone is reading the logs, which usually means a customer reports it first.
