Configuration Reference
fogwall uses layered YAML configuration merged at startup. A base file ships with the jar; additional profile files and environment variable overrides are applied on top in a defined order.
A section introducing a new config surface is tagged with the release it first shipped in, e.g.
_Available since v1.3.0._, right under the heading. Untagged sections predate this convention — it isn’t backfilled retroactively, only applied going forward from the section’s introduction.
