/**
 * Regression guard: an organization's team page must not be world-readable.
 *
 * GET /orgs/:org/teams/:team was mounted with `softAuth` and no membership
 * check of any kind, while every sibling org route required auth. It served
 * any anonymous caller:
 *
 *   - the team's full member roster (usernames)
 *   - the team's permission level (read / write / admin)
 *   - the team's repository list
 *
 * The last one is the serious part: that query joins `repositories` with no
 * `isPrivate` filter, so the NAMES of an organization's private repositories
 * leaked to anyone who could guess an org and team name. Private repo names
 * routinely disclose unreleased products, customers, and acquisitions.
 *
 * The policy being restored is not invented here — the people page states it
 * outright in its own comment ("org membership is non-public") and bounces
 * non-members. This route simply did not follow it.
 *
 * Mount only the router under test rather than importing `../app`: that is
 * one singleton shared by the whole test run, and a static import binds
 * whichever `../db` was mocked when some other file first triggered its load.
