The kernel is no longer a blind refetch pipe. Each context entry has:
{ data, status: idle|loading|success|error, error }
registerContext() returns { getState, subscribe, refetch, unregister }.
Adapters subscribe to state changes via callbacks. The kernel does
the fetch and notifies subscribers with the new state.
React adapter uses useSyncExternalStore for tear-free reads.
Vue adapter uses ref + subscribe callback.
Svelte adapter uses readable store backed by kernel subscription.
All three adapters also get:
- Mutation hooks with { mutate, isPending, error } (fixes H5)
- Vue: onServerPrefetch for Nuxt SSR (fixes M9)
- Svelte: readable store auto-cleans up on unsubscribe (fixes H9)

C1+C7: Cache purge now passes user_id and works for view-path
mutations. Extracted _purge_cache_for_invalidation() shared helper
used by both RPC and view-path branches.
C2: initSession retries 3x with backoff. Resets on total failure
so next call tries again instead of permanently broken CSRF.
C3: SSR template backend injects __MIZAN_SSR_DATA__ script tag
with serialized props for client-side hydration.
C4: SSR bridge uses _write_lock to serialize stdin writes from
concurrent Django threads. Prevents JSON interleaving.
C5: SSR bridge registers atexit handler for process cleanup.
No more orphaned Bun processes on Django reload/shutdown.
H1: pendingScoped changed from Map to Array — multiple scoped
invalidations for the same context no longer overwrite.
H2: registerContext uses stableKey() (sorted JSON) instead of
bare JSON.stringify. Property order no longer matters.
H4: Named context providers skip refetch if SSR data exists
(matches global context behavior).
H10: _meta always assigned as fresh dict, preventing shared-dict
mutation across ServerFunction subclasses.

- Fix testapp/apps.py: import djarea_clients (file was never renamed)
- Fix fetch.mjs: command is export_djarea_schema not export_mizan_schema
- Fix harness package.json: dependency path to mizan-react after restructure
- Add package.json for generator (openapi-typescript dependency)
- Regenerate all example code with new protocol format:
- generated.provider.tsx uses raw context responses + SSR hydration
- generated.server.ts uses GET /ctx/global/ with response.ok check
- generated.forms.ts, channels.ts, channels.hooks.tsx refreshed
- Remove stale generated.django.tsx and generated.django.server.ts
- Update imports: fixtures.tsx and main.tsx import from ./api (index)
- Use MizanContext instead of deprecated DjangoContext in examples

Three bugs fixed:
1. MizanProvider.call() read data.data but server returns data.result.
Now reads data.result and processes data.invalidate for server-driven
invalidation (triggering refetch on mounted context providers).
2. GlobalContextLoader expected {error, data} wrapper but context GET
returns raw bundled data. Fixed to iterate response directly.
3. Named context providers had same wrapper assumption. Fixed to
setData(result) directly.
Two features added:
1. SSR hydration: GlobalContextLoader checks window.__MIZAN_SSR_DATA__
on mount. If present, populates contexts from it and skips fetch.
2. SSR hydration: Named context providers check __MIZAN_SSR_DATA__ in
useState initializer. If SSR data exists for their functions, they
render immediately without fetching.
3. Server-driven invalidation in MizanProvider.call(): reads the
invalidate array from mutation responses and triggers refetch on
mounted providers. Generated mutation hooks' hardcoded invalidation
is now redundant but idempotent — both paths coexist safely.
Also fixed FunctionSuccessResponse type to match new protocol:
{ result: T, invalidate?: [...] }

packages/
mizan-runtime/ Framework-agnostic state engine (~150 lines)
Context registry, batched invalidation, fetch primitives
mizan-django/ Django server adapter (was packages/mizan-rpc/adapters/django/)
Codegen moved to mizan-django/generate/
mizan-react/ React adapter (was packages/mizan-csr/adapters/react/)
Removed premature abstractions: mizan-ast, mizan-schema, mizan-rpc,
mizan-csr, mizan-ssr stub packages. The actual architecture is three
concrete packages, not five abstract layers.
mizan-runtime implements the v1 spec: registerContext with params,
scoped invalidation via microtask batching, server-driven invalidation
from mutation responses, mizanFetch for context bundles, mizanCall for
mutations.
264 Django + 33 React tests pass.
