00:00:00.300 --> 00:00:01.902
Changing a resale platform

00:00:01.902 --> 00:00:03.156
should update its fee

00:00:03.156 --> 00:00:04.759
and the expected profit.

00:00:05.059 --> 00:00:05.848
In this case,

00:00:05.848 --> 00:00:07.151
the interface kept the

00:00:07.151 --> 00:00:08.797
old calculation even though

00:00:08.797 --> 00:00:10.444
the existing selected tests

00:00:10.444 --> 00:00:11.267
were green.

00:00:12.217 --> 00:00:13.422
A frontier assistant

00:00:13.422 --> 00:00:14.527
selected the risk,

00:00:14.527 --> 00:00:16.000
reproduced the defect and

00:00:16.000 --> 00:00:17.273
supplied its cause.

00:00:17.573 --> 00:00:19.365
This was assisted discovery.

00:00:19.665 --> 00:00:20.592
Grex was asked to

00:00:20.592 --> 00:00:21.883
make a bounded repair,

00:00:21.883 --> 00:00:23.803
not independently find the bug.

00:00:24.758 --> 00:00:26.403
Grex produced the calculation

00:00:26.403 --> 00:00:28.300
repair and focused regressions.

00:00:28.600 --> 00:00:29.622
2 executions were

00:00:29.622 --> 00:00:31.734
rejected because operator-authored

00:00:31.734 --> 00:00:33.506
evidence was insufficient.

00:00:33.806 --> 00:00:35.016
The third supplied the

00:00:35.016 --> 00:00:36.609
required checks and received

00:00:36.609 --> 00:00:38.137
independent acceptance.

00:00:39.092 --> 00:00:41.743
For the retained synthetic fixture,

00:00:41.743 --> 00:00:43.174
the fee changed from

00:00:43.174 --> 00:00:44.184
8 dollars 61 to

00:00:44.184 --> 00:00:45.278
6 dollars 50.

00:00:45.578 --> 00:00:47.531
Expected net changed

00:00:47.531 --> 00:00:48.399
from 28 39

00:00:48.399 --> 00:00:49.376
to 30 50.

00:00:50.342 --> 00:00:52.766
Independent verification checked the

00:00:52.766 --> 00:00:54.419
exact released frontend,

00:00:54.419 --> 00:00:55.705
3 platform choices,

00:00:55.705 --> 00:00:57.138
item and batch totals,

00:00:57.138 --> 00:00:59.195
and the existing fee override.

00:00:59.495 --> 00:01:00.471
At this release,

00:01:00.471 --> 00:01:01.750
the broader mock suite

00:01:01.750 --> 00:01:02.759
had 7 failures.

00:01:03.717 --> 00:01:04.459
The result is

00:01:04.459 --> 00:01:05.807
one verified repair.

00:01:06.107 --> 00:01:06.804
It does not

00:01:06.804 --> 00:01:09.086
establish autonomous discovery,

00:01:09.086 --> 00:01:10.749
real valuation quality,

00:01:10.749 --> 00:01:13.766
customer impact or sustained reliability.

00:01:14.066 --> 00:01:16.626
Those questions require different evidence.
