0xdhx fec42e9a7d test(#2665): cover the widened derivation, and mark what these tests cannot prove ...

Two tests for round 3's change (round 2 Blockers 1 and 2): KIMI_SHARE_DIR must
arrive via NON_REGISTRY_CONFIG_HOME_DESCRIPTORS rather than a literal, and every
GSD_LOCATION_ENV_KEYS entry must be blanked. Both assert a floor on their source
first, so a renamed export fails loudly instead of passing vacuously.
Negative-controlled against the registry-only derivation: both fail there, and
only those two.

And the Nit, which is the more useful half. This block asserts that TEST_ENV_BASE
is not narrower than the enumerations it derives from. It cannot prove those
enumerations are complete — a var no enumeration carries is invisible to every
test here, and they stay green.

That is exactly how round 2 found GSD_HOME and KIMI_SHARE_DIR while this block
was fully green: one belonged to no enumeration at all, the other sat inside a
function body where nothing could enumerate it. So the scope boundary is now
written down at the top of the block, naming where the completeness question is
actually answered — a source census re-derived each round, and
live-config-guard.cjs observing real writes at runtime — so that a green run
here is not misread as "the set is exhaustive."

Deliberately NOT added: an assertion per reviewer-named variable. That is the
hand-maintained list wearing a test's clothes, and it fails the same way.
