The comment above ADMIN_TOKEN still said "set ADMIN_TOKEN_LEGACY=0 and rotate
both". Stale — and the direct reason a report claimed a rotation was
outstanding: ADMIN_TOKEN was minted new and WEBHOOK_TOKEN rotated on 2026-10-27,
and the legacy path was closed on 2026-10-28.
Comment only, no behaviour change. Rebranched onto the current main: an earlier
attempt had pinned an image built from a tree that predated the key-encryption
work, which would have reverted it.
