bb88fd984b C6: Runtime kernel owns data, status, error — adapters subscribe
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)

cdd15b3810 Fix critical issues C1-C5, C7, H1, H2, H4, H10
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.

373 Django + 33 React tests pass.

c20de182e1 Two-stage codegen: React + Vue + Svelte from one schema
Stage 1 (framework-agnostic):
  types.ts           — OpenAPI interfaces
  contexts/<name>.ts — fetchXxxContext(params) using mizanFetch
  mutations/<name>.ts — callXxx(args) using mizanCall
  functions/<name>.ts — callXxx(args) using mizanCall
  index.ts           — re-exports

Stage 2 (per framework):
  react.tsx  — hooks + context providers + SSR hydration
  vue.ts     — composables with provide/inject + ref/computed
  svelte.ts  — writable/derived store factories

New packages:
  mizan-runtime — the kernel (~200 lines, zero framework deps)
    configure(), initSession(), registerContext(), invalidate(),
    mizanFetch(), mizanCall(), MizanError
  mizan-vue     — Vue adapter (package.json, codegen template)
  mizan-svelte  — Svelte adapter (package.json, codegen template)

CLI: mizan-generate --target react,vue,svelte
Config: target: 'react' (default) in django.config.mjs

Verified: codegen produces 33 functions across 2 contexts,
14 plain functions, 0 mutations, generating all three Stage 2
outputs from one schema fetch.

6108845d99 Rename all djarea references to mizan
- djarea_clients.py → clients.py (both example apps)
- export_djarea_schema → export_mizan_schema (management command)
- djarea.spec.ts → mizan.spec.ts (playwright test)
- fetch.mjs: command name updated
- apps.py/asgi.py: import paths updated
- Removed stale generated.djarea.* artifacts
- Fixed desktop app: asgi.py import, vite config aliases, package.json dep path

373 Django tests pass. Both example apps verified running.

658cbebce1 Regenerate example code + fix broken paths from repo restructure
- 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

711e92ac4d Fix protocol mismatch + add SSR hydration to codegen
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?: [...] }

373 Django + 33 React tests pass.

787f90fd12 Flatten to three packages + extract mizan-runtime
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.
