The first run found useful things. Good. It also left things
untested.
That is not automatically a failure of the run. A useful initial pass
is bounded. The problem is when the deferred work disappears into the
conversation and the next run starts from scratch.
/carbon-more continues from a prior broad CARBON run,
working through the next highest-value deferred candidates.
Continue the
investigation, not the ceremony
Imagine the initial checkout pass covered a successful purchase and
basic validation. The remaining candidates include an expired session,
an inventory change, and recovery after a rejected payment.
Those are not interchangeable items to consume in file order. The
next selection should reflect the current risks and what the first run
learned. If payment recovery already looks fragile, it deserves
attention before a low-impact cosmetic variation.
CARBON retains the earlier results and distinguishes new execution
from the work already done. A changed build or invalid starting state
may require a fresh check; continuity is not permission to trust stale
evidence.
Ask for a meaningful next
slice
/carbon-more continue checkout coverage for 15 minutes; prioritize session expiry and recovery using the existing sandbox
The follow-up report should tell you what additional uncertainty was
reduced, what failures were confirmed, and what is still deferred. Ten
new checks that all repeat the same assumption are less useful than one
that challenges an important blind spot.
This is a convenient way to deepen testing without making the first
experience an overnight assignment. Start with enough evidence to orient
yourself. Then spend the next chunk of attention where it can make a
difference.
