Re-stating the architectural intent that got silently swapped to "JSON
schema" during the doc-restoration commit (6eca514). The original
AFI_ARCHITECTURE positioned KDL as the LLVM-IR-equivalent of the
system; I read the stale-package-name note at the bottom as
invalidating the whole architecture description and substituted
JSON-schema references thinking that was the more-current intent.
That conflated implementation drift (mizan-ast/mizan-schema package
names) with substrate intent (KDL is the IR). The packages had
drifted; the IR target had not. Restoring the section.
Frames KDL-as-IR explicitly as forward-direction. The current
OpenAPI/JSON-Schema codegen path is transitional — it's the layered
indirection where adapter divergence lives (AFI conformance suite
demonstrates this). Real KDL implementation lives in a forthcoming
mizan-schema package; today's path is sediment around the eventual
substrate.
