Round 4 of Raincloud conformance triage (#205), against a fully-fixed build.

8/10 pass value-for-value: bi-food (5.2M rows), bi-corporations (742k×27), bi-iglocations1, bi-iublibrary, sf-salaries (1M×26 — decimal path clean post-#197), uci-automobile, uci-thyroid-disease (heavy nulls), marketing-data.

2 new gaps, both silent null loss in lazy decoders (same class as the fixed #210), pinned in the matrix:

Matrix: 38 ok / 2 gaps / 207 untriaged; conformance suite 41/41 over 40 hydrated slugs. No rotted URLs.

8 ok incl. bi-food (5.2M rows), bi-corporations (742k×27), sf-salaries
(1M×26, decimal path clean), uci-automobile, uci-thyroid-disease.
2 new gaps, both silent null loss in lazy decoders: uci-online-retail
(gap:225, RunEnd nullable run-values validity dropped) and
world-energy-consumption (gap:226, Sparse null fill coerced to 0 +
nullable patch values stripped). Both the same class as the fixed #210.

Nullable ALP flat columns drop row validity — nulls export as invented values (silent corruption)
