pub const REPOSITORY_READ_ONLY_GATE: StructuralGate;Expand description
A backup refused because its repository is mode: ReadOnly.
Unlike the other rows this is NOT an invisible park: the writer
(snapshot/mod.rs) sets phase: Failed in the same status patch, so a
phase-based check already sees the object. It is registered for EXPLANATORY
value — it turns “this backup failed” into “this backup was refused because
the repository is read-only” without a second lookup. Hence WARN, not Fail:
a read-only repository is a legitimate, deliberate configuration (a
replication target, an archived repo served for restores only), so a
green/red verdict must not hinge on it.
