Replaces the transitional OpenAPI 3.0 + `x-mizan-*` extensions
substrate with the canonical Mizan IR as KDL, per docs/AFI_ARCHITECTURE.md:
"KDL is the contract; everything else (REST envelopes, OpenAPI
documents, framework idioms) is sediment around it."
End-to-end cutover. No transitional path left on main.
Forward direction:
cores/mizan-python/src/mizan_core/ir.py
build_ir() walks mizan_core.registry, introspects Pydantic
models directly (no JSON-Schema indirection), and emits the
Mizan IR document. The KDL grammar is locked in this file's
module docstring.
Backends emit KDL:
backends/mizan-fastapi/src/mizan_fastapi/ir.py
`python -m mizan_fastapi.ir <module>` — CLI entry point.
backends/mizan-django/.../management/commands/export_mizan_ir.py
`manage.py export_mizan_ir` — Django mgmt command.
Codegen consumes KDL:
protocol/mizan-codegen/Cargo.toml: + kdl = "6"
protocol/mizan-codegen/src/ir.rs: NamedType { Struct/List/Enum/Alias }
+ TypeShape { Primitive/Ref/List/Optional/Enum/Union } sum types,
replacing the JsonSchema sprawl. KDL parser walks the
`kdl::KdlDocument` tree into typed Rust structs.
protocol/mizan-codegen/src/fetch.rs: subprocess command switches
to the new IR-export entry points.
All emit modules (stage1 / react / python / rust / vue / svelte /
channels) port their type-walkers from JsonSchema to the new
sum types — case analysis collapses substantially.
Substrate-honesty wins beyond the moat closure:
- `int | bool` multi-arm unions land as `TypeShape::Union` (was
silently coerced to "string" before).
- `<CamelName>Output = list[T]` returns emit as named alias
types instead of struct-shaped wrappers, so consumer code
`.map()` works directly on the type.
- Pydantic field defaults flow through to `default` properties
in KDL, then back to non-optional shape in every target.
Deleted:
- backends/mizan-fastapi/src/mizan_fastapi/{cli,schema}.py
- backends/mizan-django/.../export_mizan_schema.py
- openapi-bearing half of mizan/export/__init__.py (edge
manifest generator preserved — separate concern).
- tests/afi/schema_normalizer.py
- tests/fixtures/{afi_schema.json, channels_schema.json}
- tests/fixtures/js_* baseline directories.
Verification:
- 20 mizan-codegen unit tests green (IR deserialization,
byte-equivalence parity across stage1/rust/python/react/vue/svelte
against fresh KDL-driven baselines, channels structural).
- tests/rust/run_wire_parity.py: 12/12 probes green driving
the binary end-to-end through KDL.
- Blazr studio-ui typechecks against the regenerated React client.

AFI conformance — same @client fixture, same Mizan IR (KDL), both adapters.

Gates that mizan-django and mizan-fastapi emit byte-equivalent IR
