f660dd6bd wrote the placeholder into a parameter expansion, `${INFINITO_IMAGE:-<none, bootstrap will build it>}`, which tests/lint/filesystem/shell/test_no_infinito_defaults.py rejects: an INFINITO_* default in a shell file is a second source next to default.env that drifts silently, and only the empty form is allowed. It was the sole failure of test-lint.
Split the message into the resolved and the unresolved case instead of suppressing the lint; the output is also no longer self-contradictory, since 'published <none>' could not both be true.

Swarm test routine 🔁
Sequenced steps of the swarm lab run. Bring-up and the chaos phase are
workflow steps; the per-round loop in between is driven by
utils.tests.swarm.matrix (one round per variant of the
primary app). Highlighted boxes (⚡) are the moments a backup-executing
systemd unit actually starts. See ../README.md for
topology, naming SPOTs and helpers; the DR drill's own steps are
documented in backup/README.md.
