Found by reading the first REAL digest, not by design. Every app row ended with
the same usage clause the mail already prints once on its own Filesystem line.
On a two-app box that is untidy; down a list of a dozen it is the same forty
characters twelve times, pushing the part that DIFFERS off a phone screen at
07:00 — the only moment this mail has to work.
The reserve's refusal message is authored for a single-app alert where naming
the filesystem is right, so the message is unchanged; the digest trims the
duplicate when rendering. trimRepeatedUsage removes ONLY an exact
"— <target path>:" suffix, so an unrelated reason is untouched and a reason that
is nothing but the usage clause is left alone rather than emptied.
Also updates TestRecoveryUnitCaptureFailed_NeverReachesTheCustomer, which
required the OPERATOR to be emailed a per-app capture failure. That was correct
when the event was the only signal and is wrong now that it is the record and
the digest is the notification. Its customer-safety claim is unchanged and is
why the test still exists; the operator assertion is inverted with the reasoning
written in place, and R-158's guarantee is shown to have MOVED, not weakened.
New OPERATOR-ONLY event type recovery_unit_capture_failed (controller
v0.191.0, R-158): in allowedEventTypes AND notify.operatorOnlyEvents.
Deliberately not a reuse of backup_failed, which carries customer copy and
sits in the controller's DefaultEnabledEvents — reusing it would email the
customer in Hungarian about a failure they cannot act on. R-158's own
proposal said backup_failed; D-c overrides it.
disk_warning/disk_critical lose their generic customerMessages entries.
Both were allowlisted, copy'd, default-enabled and checkbox'd with NO
producer anywhere; controller v0.191.0 becomes that producer and sends a
DYNAMIC Hungarian message naming the drive and its free space.
FormatCustomerEmail prefers the entry over the message, so keeping a static
entry would discard the label and the byte figures — the same reason
offbox_enlarge_blocked and disk_health_degraded have none. The deletion is
pinned by a test.
New notify.IsOperatorOnly so the api package can pin BOTH registers of a new
event type in ONE test; allowlisted-but-not-operator-only is invisible when
they are checked separately, and it is the defect v0.78.0 shipped. The
register itself stays unexported.
REUSE.md's "new event type" extension point rewritten: it told readers to
always add a customerMessages entry, which is wrong for operator-only types
and harmful for dynamic-message ones.
Tests 574 -> 579. Red-proof: removing the operatorOnlyEvents entry shows the
customer being emailed; the skipped/operator_only row is asserted as a
positive observable.
