ROADMAP: done items moved out of "Next" (codegen rewrite, SSR bridge, edge manifest, X-Mizan-Invalidate, return-type branching, affects_params, kernel extraction, two-stage codegen, mizan-ts). Real "Next" in: framework-adapter wrapper layer (MizanContext + useMizan + DjangoError on top of the kernel) for React/Vue/Svelte; A1–A4 from ISSUES.md. CLAUDE: 4-package layout replaced with the actual 7-package layered architecture (backend protocol adapters + frontend kernel + framework adapters + SSR worker). "STALE codegen" section rewritten to describe what's emitted vs. the wrapper layer that isn't yet. docs/ now tracked (6 files). AFI_ARCHITECTURE rewritten — replaced the speculative `mizan-ast`/`mizan-csr`/`mizan-rpc`/`mizan-schema` package names with the real layout, dropped KDL-schema language for the actual schema-export format. The other 5 docs/ files were already current and are tracked as-is. ARCHITECTURE-REWORK.md deleted — same expert review is re-tracked in the fresher ISSUES.md, two parallel trackers was sediment. README.md deleted — drift was beyond surgical fixes (`mizan_clients.py` convention, `<DjangoContext>` provider, removed `@compose` and `context='local'`, wrong codegen output filenames, 3-package structure vs. 7). Rewrite waits for the wrapper-layer codegen to land so user-facing examples reflect reality. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

# Mizan Roadmap
|
||
|
||
## v1 — Django + Multi-Framework (React, Vue, Svelte)
|
||
|
||
### Done
|
||
|
||
- **`@client` decorator** — `context=`, `affects=`, `auth=`, `websocket=`, `private=`, `route=`, `methods=`, `rev=`, `cache=`
|
||
- **`ReactContext` class** — type-safe context/affects references with linting
|
||
- **Named contexts** — functions sharing a context name grouped into one provider and one fetch
|
||
- **Context bundling endpoint** — `GET /api/mizan/ctx/<name>/` returns all functions in one response
|
||
- **Server-driven invalidation (JSON body)** — mutation responses carry `{"result": ..., "invalidate": [...]}`
|
||
- **`X-Mizan-Invalidate` header** — second invalidation transport for view-path responses (redirects, HTML)
|
||
- **Return-type branching** — data return → RPC path; `HttpResponse` return → view path
|
||
- **Scoped invalidation** — `affects_params` lambda; runtime supports `{context, params}` form
|
||
- **Auth guards** — `auth=True`, `auth='staff'`, `auth='superuser'`, `auth=callable`
|
||
- **JWT + session auth** — auto-detected, CSRF handled
|
||
- **MWT** — Mizan Web Token for Edge cache keying (separate secret from JWT/cache)
|
||
- **Shapes** — Pydantic + django-readers for typed query projections
|
||
- **WebSocket channels** — real-time bidirectional communication
|
||
- **HMAC cache keying** — origin-side cache with cross-language HMAC conformance (Python + TypeScript pin)
|
||
- **Edge manifest** — `python manage.py export_edge_manifest`; both RPC and view-path functions
|
||
- **SSR bridge** — Django template backend → persistent Bun subprocess via JSON-RPC
|
||
- **`mizan-runtime` kernel** — framework-agnostic imperative client primitives (data/status/error owned by kernel)
|
||
- **Two-stage codegen** — Stage 1 emits framework-agnostic protocol layer; Stage 2 emits per-framework hooks (React, Vue, Svelte)
|
||
- **`mizan-ts`** — TypeScript backend adapter; proves the protocol is language-agnostic
|
||
|
||
---
|
||
|
||
### Next (in progress)
|
||
|
||
- **React adapter wrapper layer** — codegen emits `MizanContext` provider, `useMizan` hook, `DjangoError` class on top of the `mizan-runtime` kernel. Equivalent wrapper layers for Vue and Svelte adapters. The harness in `examples/django-react-site` is blocked on this.
|
||
- **Legacy `MizanProvider` removal (A1)** — `mizan-react/src/context.tsx` (~750 lines) replaced by codegen-emitted wrappers. Blocks v1 `mizan-react` publishing.
|
||
- **Forms migration to kernel (A3)** — `mizan-react/src/forms.ts` (~1163 lines) currently consumes legacy `MizanProvider`. Rewrite to use `mizanCall` from the kernel. Blocks A1.
|
||
- **Allauth extraction (A2)** — `legacy/allauth/` becomes `mizan-django-allauth` package consuming Mizan's public API.
|
||
- **Vue/Svelte e2e validation (A4)** — example apps exercising a live backend end-to-end, like `examples/django-react-site` does for React.
|
||
- **Test coverage gaps** — T1–T12 in `ISSUES.md` (kernel state machine, view-path purge, SSR thread safety, retry logic, cross-language HMAC pin, etc.)
|
||

|
||
|
||
### Quality
|
||
|
||
- **H5** — Mutation hooks expose no loading/error state
|
||
- **H7** — Redis SCAN blocks request path at scale
|
||
- **H8** — Svelte codegen uses Svelte 4 stores; should use Svelte 5 runes
|
||
- **H9** — Svelte `destroy()` not auto-called (memory leak)
|
||
- **H12** — Forms `triggerValidation` captures stale data
|
||
- Medium issues (M1–M18) per developer judgment
|
||

## Mizan Cloud (closed-source)
|
||
|
||
### Mizan Edge
|
||
|
||
Cloudflare Workers for automatic edge caching.
|
||
|
||
- Reads the edge manifest to configure cache rules
|
||
- Context GETs cached at edge, keyed by context name + params
|
||
- Reads `X-Mizan-Invalidate` header from mutation responses to purge caches
|
||
- Reads JSON `invalidate` key from RPC responses for the same purpose
|
||
- Resolves URL patterns from manifest to purge view pages
|
||
- Zero configuration — the manifest IS the cache policy
|
||
|
||
### Mizan Render
|
||
|
||
SSR at the edge via Cloudflare Workers.
|
||
|
||
- The Bun SSR bridge, running on Cloudflare instead of colocated with Django
|
||
- Context data fetched from Django (or edge cache), rendered at the edge
|
||
- HTML response streamed to the user from the nearest PoP
|
||
|
||
### Mizan Deploy
|
||
|
||
One-command deployment for Django + React apps.
|
||
|
||
- Container orchestration (AWS/Azure)
|
||
- Edge + Render auto-configured
|
||
- `mizan deploy` from the CLI
|
||
- The Vercel experience for Django
