Three specs completing the set, each depending on the one before it:
- apis {}: one container, mode-less declarations, api.<name>() callable
anywhere with build-time dispatch, AsyncLocalStorage for server context,
usage-driven emission, three render-binding forms. Replaces the ssr {} /
client {} data blocks and the untypeable with($data) legacy body.
- update: migrations to the new syntax. The legacy bare-body rewrite is
deliberately manual -- which free identifiers are payload fields is not
knowable from the source, so an automatic guess would compile and be wrong.
- editor tooling: grammar, completions for api. and the api= attribute,
diagnostics for removed constructs, and resolving by observation whether
generated type errors surface inline.

All seven compatibility keys are dead configuration: traced every reference
and none is read by any compiler, codegen, or runtime code. They are written
into every generated config and ignored.

Client codegen chained .then().catch(), so a .catch() after .then()
caught exceptions thrown by the response body too. Switched to the
two-argument then(onFulfilled, onRejected) form, whose rejection
handler cannot see errors from the fulfilment handler.
SSR codegen wrapped both the transport call and the response-body eval
in the same try; only __wrnexusCallApi is now inside the try, and
__wrnexusEvalData runs after it, outside.
Also verifies (and locks in with a regression test) that GET query
numbers already coerce correctly through defineEndpoint + checkField,
and documents that in the typed-api-block spec.
Assertions in a .d.ts are inert under skipLibCheck: true, which the root
tsconfig sets. Proven during implementation by forcing skipLibCheck: false,
where the same assertion fires as TS2344. They move to a generated .ts file,
which skipLibCheck does not exempt.

Six tasks: parse the sections, add the CSR transport, compile client-mode
blocks into the browser module, generate the tsc assertions, support
sections in ssr blocks, and verify end to end in a browser.

A sectioned `api` block -- request / response / error -- callable on
demand from client code, typed against the API route contracts the types
generator already emits.
Records the constraints that shaped it: the current block cannot carry a
query string (isSafeApiPath rejects "?"), cannot interpolate (readPath
stops at "{"), has nowhere to put a body, and fetches once. And the one
that decides the type-safety mechanism -- generated build artifacts are
not type-checked, so enforcement goes into the generated .d.ts, which the
project's own tsc already compiles.

Eight TDD tasks: the view-block scanner and virtual document, the HTML
service wrapper, merging HTML into completion and hover, folding and
linked editing, auto-close on type, standing down the duplicate client
provider, manifest guards, and a manual editor check.
Task 1 comes first because everything reads positions through it: its
length-and-newline invariant is what removes position mapping, and a
break there would misreport positions everywhere rather than fail.
The last task is manual verification in an Extension Development Host.
Unit tests cannot show that completions actually appear in an editor, and
a green suite has hidden non-functional features in this repo before.

Markup in a .wrn file highlights but has no tag or attribute completion,
no tag closing, and no tag-level folding: the grammar's embeddedLanguages
mapping only affects tokenization, and VS Code's HTML language service
never runs on these documents.
The design extracts view blocks into a virtual HTML document where
everything outside them is blanked to whitespace of identical length, so
source positions and virtual positions are the same and no mapping table
is needed. Region detection is a tolerant scanner rather than the parser,
because completion fires while the document is mid-edit and unparseable.
Completion merges WRNexus and HTML entries into one list ranked by
sortText, which also fixes an existing bug: the extension and the server
both answer completion on '<' today, so VS Code concatenates two lists.
Two decisions worth review:
- HTML formatting is excluded. formatWrn already formats markup, knows
WRNexus syntax, and would fight a second formatter that is free to
rewrite spacing inside @click={...} and client:visible.
- Only auto-close-on-type is client-side. Linked editing is standard LSP
and lives in the shared server.

Implemented and removed. A render-phase flag cleared on a microtask is
still set when React runs effects, so islands writing from an effect —
the documented correct pattern — would throw. The flag also cannot be
set for an island's own re-renders, so real violations pass silently.
Detecting React's render phase reliably needs React internals, which is
not acceptable in a shipped framework. React already reports the real
hazard, and the getSnapshot caching requirement covers the loop case.

Twelve TDD tasks covering the approved spec: snapshot cache, store
bridge, marker codegen, .tsx resolution, error boundary, island runtime,
bundling with a shared React chunk, asset serving, route classification,
integration guards, the write-during-render guard, and HMR remount.

Adds the approved design for consuming npm React components as
client-only islands inside WRNexus, without changing the SSR-first
rendering model.
Key decisions:
- New isolated @wrnexus/react package; react/react-dom as optional peers
- Client-only by default, SSR deferred to v2
- Islands declared via .tsx imports in .wrn frontmatter
- Store access via useSyncExternalStore, with the snapshot cache in the
adapter so @wrnexus/store stays untouched
- Bundling extends the existing Bun pipeline; React as a shared chunk
- Routes with no islands must still ship zero framework JavaScript
