Engineer-reviewable questions, every data-dependent one with a pinned time

- has never been run as a gate. No scorecard exists. Two cases fail by design until the historian

The whole set was put through the live assistant on 1 September, 01:01–02:08
+ UTC — every question, found in the assistant’s own trace log. Two things are wrong
+ with it as a gate:
it ran nine hours before the seed was re-keyed, so it scored a system
+ that no longer exists; and
no scorecard was kept, so there is no result to read. A run
+ against the current build is planned. Earlier, the 67-question version passed for weeks against
+ the stand-in model — which is why it caught none of the eight failures that appeared
+ minutes after the first real model call on 27 August. Two cases fail by design until the
+ historian lands.

Twenty-eight containers on one shared host. Seven are ours; twenty-one were

Deliberate shortcuts, all reversible
Documented rather than hidden, and none of them to be shipped. Production closes
them in this order: network separation, then secrets, then database guardrails, then document
control integration, then resilience.
