The original registry tangled function, channel, composition, and form
registration in a single file with polymorphic register() dispatch.
That predates the household discipline; it was the design that was
supposed to ship but didn't. Re-implementing the original intent.
cores/mizan-python/src/mizan_core/registry.py (new):
- _functions, _compositions dicts
- register() — ServerFunction-only, no polymorphic dispatch
- register_as(), register_compose()
- register_extension(name, extension) — hook interface
- get_function/get_compose/get_all_functions/get_all_compositions
- get_contexts, get_context_groups
- get_registry, get_schema — aggregate extension contributions
- validate_registry, clear_registry — cascade-clear extensions
RegistryExtension Protocol:
- schema() returns the extension's schema subdict (keyed under its name)
- clear() resets extension state (called by clear_registry)
mizan-django/src/mizan/channels/__init__.py:
- _ChannelsExtension wraps the channel _registry, plugs into core via
register_extension('channels', ...). Schema output preserves the
same shape codegen consumed before (snake_case keys, type+bidirectional).
mizan-django/src/mizan/forms/__init__.py:
- register_form() and get_forms() helpers moved here (were in setup/registry.py)
- Both use mizan_core.registry under the hood. Forms don't need a
separate extension because form sub-functions register as regular
ServerFunctions with meta.form set.
mizan-django/src/mizan/setup/registry.py: deleted.
mizan-django/src/mizan/setup/__init__.py: re-exports the registry helpers
from mizan_core.registry / mizan.channels / mizan.forms — the Django
adapter's curated public API surface stays stable for users.
Consumers updated: ~10 files imported `from mizan.setup.registry`;
all switched to direct imports from mizan_core.registry, mizan.channels,
or mizan.forms as appropriate. ChannelTests in test_core.py rewritten
to use mizan.channels.register directly (no more polymorphic
@register_as on ReactChannel subclasses).
Verified:
- mizan-core: 15/15
- mizan-django: 348 pass, 21 skip, 0 fail
- mizan-ts edge-compat: 34/34 (cross-language pin holds)

cache/backend.py is pure framework-agnostic key-value abstraction —
CacheBackend Protocol, MemoryCache, RedisCache. No Django imports.
Moves to cores/mizan-python/src/mizan_core/cache/backend.py with no
content changes; mizan-django re-imports.
Verified: mizan-core 15/15, mizan-django 348 pass / 21 skip.

Pull cache/keys.py (HMAC cache key derivation) and mwt.py (Mizan Web Token)
out of backends/mizan-django and into a new cores/mizan-python package.
mizan-django re-imports them via the new mizan_core module.
Naming: directory cores/mizan-python/, distribution mizan-core, importable
module mizan_core. mizan-django keeps its existing 'mizan' distribution slot
on PyPI; the two coexist as distinct packages.
Wiring:
- backends/mizan-django/pyproject.toml gains a 'mizan-core' dep with a
[tool.uv.sources] path entry (editable install from ../../cores/mizan-python).
- Makefile install target prepends 'cd cores/mizan-python && uv pip install -e .'
- 3 import sites in mizan-django updated: cache/__init__.py, jwt/functions.py,
client/executor.py — all now import from mizan_core.
Test split:
- 3 unit-test classes (CacheKeyDerivationTests, MWTCreationTests,
PermissionKeyTests) move to cores/mizan-python/tests/, rewritten against
unittest.TestCase (no Django dep). The cross-language pin test (pinned
HMAC hex digests against mizan-ts) moves with CacheKeyDerivationTests.
- Integration tests stay in mizan-django (CacheBackendTests, CachePurgeTests,
CacheIntegrationTests, RevParameterTests, MWTAuthIntegrationTests) — they
need the Django request flow.
Verified:
- mizan-core: 15/15 pass (incl. cross-language pin)
- mizan-django: 348 pass, 21 skip, 0 fail
- mizan-ts: edge-compat 34/34 pass — protocol invariant holds, the moved
Python derive_cache_key still produces the exact hex digests TS pins against.
