# Mizan — Known Issues

Status board against the current codebase: Rust codegen (`protocol/mizan-codegen`),
KDL IR, kernel-owned frontend state (`@mizan/base`). Issues that the earlier
expert-review board filed against the deleted JavaScript codegen and the
pre-kernel `mizan-react` provider have been removed — they audited files that
no longer exist.

## Open

- [ ] **Vue / Svelte frontend packages are unimplemented stubs.** `frontends/mizan-vue` and `frontends/mizan-svelte` contain only a `package.json` — no `src/`. The Rust codegen emits Vue composables and Svelte stores (`src/emit/vue.rs`, `src/emit/svelte.rs`, byte-checked by `vue_svelte_parity.rs`), but there is no runtime kernel-adapter package for either and no example app exercises them against a live backend. React is the only frontend with full integration verification.
- [ ] **Svelte adapter emits Svelte 4 stores.** `src/emit/svelte.rs` generates `readable` stores from `svelte/store`. Svelte 5 `$state`/`$derived` runes are the current idiom.
- [ ] **Forms have no codegen target.** `mizan-react/src/forms.ts` (form core hooks) is hand-written and consumed via the pre-kernel `MizanProvider`; the e2e harness has its form fixtures removed. A form codegen target wired to `mizanCall` is owed.
- [ ] **Pre-kernel MizanProvider still shipped.** `mizan-react/src/context.tsx` (~750 lines) is the pre-kernel provider, still imported by the desktop example. It coexists with the codegen-emitted `MizanContext` (which subscribes to `@mizan/base`). Migrating the desktop example onto the generated provider retires it.
- [ ] **Cache module open issues.** See `backends/mizan-django/src/mizan/cache/KNOWN_ISSUES.md`: purge atomicity, cross-language stringification, per-param sub-index cleanup, thundering-herd protection, `cache_get`/`cache_put` argument inconsistency, RedisCache test coverage.
- [ ] **Packages missing a README.** `frontends/mizan-base` (the kernel everything imports), `protocol/mizan-codegen` (the codegen binary), `frontends/mizan-vue`, `frontends/mizan-svelte`, `frontends/mizan-rust`, `backends/mizan-ts`, `backends/mizan-rust-axum`, `cores/mizan-python`.

## Resolved this pass

- [x] **Codegen test suite compile break** — every `mizan-codegen` test constructed `SourceConfig` without the `rust`/`script` fields added alongside the Rust-backend work. Suite now compiles and is green.
- [x] **React parity baseline** — the emitter correctly drops the dead `initSession`/`MizanError` top-level imports (they are only re-exported, never used in the module body); baseline regenerated. Fixed the template whitespace artifact that indented the `} from '@mizan/base'` closing brace.
- [x] **Edge manifest non-determinism** — `generate_edge_manifest` iterated registration order; now sorts context and mutation keys, so the manifest is deterministic regardless of registration order.
- [x] **Dead code removed** — `workers/mizan-ssr/src/test-worker.tsx` (a relic of the rejected `registerComponent` registry), unused TS helpers `isResponseReturn` and `sortedStringify` (mizan-ts), the unused `IndexMap` import (`emit/python.rs`), the dead `debug_expose_names` Django setting, and the dead `package.json` exports + vite aliases (`./client/nextjs`, `./allauth`, `./allauth/nextjs`) pointing at source that does not exist.
