Six fixes, all found by driving a real application rather than by the suite:
- syntax: a quote or brace inside a regex literal unbalanced the brace scanner
- syntax: block comments between members failed to parse, while the same
comment inside a braced body was fine
- compiler: pages never emitted `data-wrn-loop-locals`, so a loop variable in
a handler threw ReferenceError at click time with a green build
- csr: client-rendered `data-for` items never carried the marker either, so a
component's output binding silently dropped every call while a plain DOM
handler in the same position worked
- db: the query generator baked the checkout's line endings into generated
SQL literals, so every build dirtied the working tree

Three things the gate caught that the test suite could not.
The runtime size budget: writing `data-wrn-loop-locals` on client-rendered
loop items pushed reactive-runtime.ts to 51,603 against a 51,400 budget that
had only 125 bytes of headroom. Trimmed the encoder to the
btoa/encodeURIComponent idiom, recovering 65 bytes and leaving the smallest
form that still handles non-ASCII, then raised the budget to 51,600 with the
reason recorded in the file's own convention -- the remaining 263 bytes buy a
correctness fix, not a feature.
The VS Code extension bundles its own copy of the compiler, so the syntax and
compiler fixes made it stale. Rebuilt.
And a bug in the new test: `\{` inside a template literal is an unnecessary
escape, so the "brace inside a regex" case was testing an unescaped brace.
`\{` tests the case it was written for.

A client `data-for` passed its loop locals to hydration in memory but never
wrote the `data-wrn-loop-locals` attribute the SSR path writes. Anything that
resolves locals by READING the DOM -- notably a component's `data-wrn-out-*`
output binding, which calls `decodeLoopLocals(componentRoot)` -- therefore
found nothing and silently dropped the call, with no console error.
A plain DOM handler kept working, because it receives locals through the
hydration closure instead, which is what made the failure look arbitrary: the
same loop variable resolved for `@click` and vanished for a component output.
Both loop paths write the marker now, keyed and non-keyed, so the DOM is the
single source of truth. Encoding goes through UTF-8 before base64 as the
server's does; `btoa` on a raw string throws above U+00FF, which would take the
whole loop down for an ordinary non-ASCII label.

A parent writing @focus on a component tag never heard that component's
own input or button take focus. The runtime bound every output-named DOM
fallback listener in the bubble phase, and focus and blur do not bubble,
so the event fired on the descendant and stopped there. Nothing errored --
the binding simply did nothing.
That made a whole class of declared outputs undeliverable: button.focus,
button.blur, TextLink.focus, TextLink.blur, WysiwygEditor.focus and
WysiwygEditor.blur all advertised events they could never send.
The ui ratchet for outputs nothing emits excluded natively-named outputs
on the grounds that a native event reaches the root anyway. That holds for
click and change, which bubble, and was wrong for focus and blur. Binding
those two in the capture phase makes the exclusion honest rather than
convenient; the ratchet's comment now says so.
Also documents WysiwygEditor as the chrome shell it is: it emits none of
its four outputs itself, it forwards whatever the slotted control raises.

Ships the apis { } block, the legacy/config cleanup, the wrnexus update
migrations, and the editor tooling that understands all of it.

The old assertions only searched REACTIVE_RUNTIME for substrings; they never
touched buildApiRequest and were not anchored to the content-type line they
claimed to guard, so they could not detect drift on either side. Replace
with a fixture-driven test that runs both implementations on the same
(path, method, input) cases and compares the actual request they produce.

Typed, callable api blocks for .wrn files: sectioned request/response/error,
callable from client code as api.name(input), type-checked by tsc against the
route contracts.
Also two fixes found along the way: defineEndpoint never received its input
through the real router, so every typed endpoint was validating undefined; and
v.boolean() silently coerced any unrecognised string to false.

B1: qualify each generated __wrn_api_check_* assertion name with a short
hash of the page's path (relative to app/, for reproducibility across
checkouts) so two pages declaring a same-named block no longer collide
with an identical type alias (TS2300).
B2: skip assertion emission for any block that is not client-mode, or
that has zero declared request fields. ssr sectioned blocks can never
declare a request and always fell back to Record<string, never>, whose
keyof is `string` -- making the key-exactness arm of AssertAssignable
evaluate to false unconditionally (TS2344) on every ssr sectioned block
regardless of correctness. Chose to skip both non-client blocks and
zero-field client blocks, since neither has anything meaningful to
assert type-safety about.
B3: only resolve the endpoint's input (query params / ctx.req.json())
when the endpoint declares an input schema. Previously the router-set
fix accidentally read the request body unconditionally, so a handler
with no input schema that parses the request itself hit
ERR_BODY_ALREADY_USED.
B4: run response/error bodies in client-mode api blocks through
eraseFunctionTypes, matching every other browser-bound body in
client-codegen.ts, so a TypeScript-only construct inside one (e.g. an
annotated locally-declared function) doesn't reach the .mjs artifact.
B5: only exclude "api" from state/prop destructuring in the generated
browser module when the page actually has client-mode api blocks (i.e.
there is a real `api` binding to shadow). Previously "api" was always
excluded, so a page with `state api` and no api blocks got an
undeclared `api` reference (ReferenceError) in client code.
B6: prefix each emitted assertion with `export`, so it isn't flagged as
an unused local under a downstream project's noUnusedLocals (TS6196).
B7: wrnexusCallApi now resolves with undefined for an ok 204/205
response, or an ok response with an empty/unparseable body, instead of
rejecting with "Response was not valid JSON" -- matching the spec's
failure table (error path only for non-2xx, network failure, or an
actually unparseable body on a non-empty response).
Regenerated examples/basic-app's generated types and editor bundles to
match. Confirmed the example's type gate still fails when an
unaccepted field is added to a request body, and passes cleanly
otherwise.

- Add examples/basic-app/app/api/directory.ts and app/pages/api-block-demo.wrn
as the end-to-end worked example for typed api blocks (Task 6).
- Add **/*.generated.api-checks.ts to .prettierignore: this generated file
must match the CLI's raw output byte-for-byte for check:generated-types,
and prettier was reformatting it.
- Fix packages/csr/test/api-call.test.ts: no-unsafe-function-type lint error
from the raw Function type, uncovered while running the full gate.
- Rebuild editors/vscode bundles (packages/compiler and packages/syntax
changed in Tasks 1-5).
- Regenerate docs/public-api-0.8.json (additive: isIdentPart, isIdentStart,
skipLiteralOrComment newly exported from packages/syntax).

Client control blocks and loops, the dev-server rebuild recycle, the
editor's tag and completion handling, and the island mount/HMR fixes.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Three pre-existing issues that the previous commit worked around rather
than solved.
Test global pollution. packages/csr's suites install a happy-dom window
over the real globals and delete them before each test. bun test runs one
file at a time, so those deletions outlived the file and later suites
failed with "fetch is not a function" -- 20 failures from `bun test` with
no argument. They now restore what they captured. The editor's Node tests
shim the vscode host by patching Module._load, which Bun's resolver does
not consult; the shim registers a virtual module under Bun instead, so the
same files pass under both runners.
Multi-cursor tag auto-close. The handler now closes the tag at every
caret. Positions come from the editor's selections rather than the change
ranges, which are in pre-edit coordinates and are short by the preceding
insertions once several carets share a line. One insertSnippet call
carries them all, since inserting sequentially would collapse the
selection to the first snippet. Carets wanting different closing tags are
declined rather than half-applied. Moved to its own module so it can be
tested without loading the language client.
Runtime size. Trimmed 2,414 bytes: the global lookup tables became one
prototype-safe scheme (a name like "toString" was previously a hit on
Object.prototype), shared hasOwn/toArray/pairBinding helpers replaced the
repeated chains, and dead code went. That was everything available without
dropping or deferring a feature -- 49,000 was not reachable, so the budget
is now 50,500, set just above the real figure so future growth trips it.
Two tests changed: one asserted on runtime source text and now asserts the
timers resolve; a new one covers reactive class bindings inside data-for,
which the enclosing loop effect tracks rather than each binding.

The client runtime had no loop support, so any shared function using one
returned early -- Pagination and ButtonGroup were broken client-side, not
just in tests.
Adding loops exposed two further faults:
- A var reaching writeScope creates a signal and triggers a render sweep.
A declaration inside a function called during a render therefore looped
forever. Declarations now bind into the handler locals instead.
- A control block removed from the DOM keeps its effect in the renderers
list. Running it against a detached node threw, aborting the sweep and
leaving every later effect stale.
Also raises the reactive runtime budget to 53,000: the runtime had already
grown past 49,000 before this change, and 52,570 minified is 16,803 gzipped.
Two deferred minors: html-service leaves absent documentation undefined
rather than an empty string, and the extension declines tag auto-close on
multi-cursor edits rather than closing only the first cursor.

{#if}, {#each} and their {:else}/{:else if}/{:empty} branches worked on
the server and after hydration, but a block nested inside another block
stayed empty once the outer block rerendered. Adding a row to a list
produced the row's markup with its inner block markers in place and
nothing between them, for the life of the page.
Two causes, both on the client-created path only:
reactive() registers an effect; effects run when renderAll sweeps the
list. A state change runs just the affected effects rather than sweeping,
so an effect registered during that rerender was queued and never
invoked. setupControlBlock now returns its runner and the creating block
invokes it immediately.
The first reactive pass is skipped so hydration does not discard
server-rendered DOM. A block created by a rerender has no server DOM, so
skipping its only pass left it permanently empty. firstRun is now keyed
off outerLocals, which is set only on the client-created path.
Verified in a browser as well as in tests: adding a group to a list now
renders the new row's nested {:else}, and the existing rows' nested loops
survive the rerender.

cli 0.8.42, csr 0.8.22, db 0.8.16, dev-server 0.8.38,
dev-toolbar 0.8.13, i18n 0.8.12.
Every previous version was already on the registry, so the HMR client
repair, the i18n JSON data block, the gateway WebSocket origin fix, and
the generated-dialect stamp were not reachable by consumers.
compiler and react are unchanged since their last publish and are not
bumped.

window.__wrnI18n was undefined in development: the payload shipped as an
executable inline script, and a document's CSP nonce is fixed at load, so
any such script arriving from a later response is blocked. Client
translations and language switching silently had no data.
The payload is now a type="application/json" block, which the browser
never executes and script-src therefore never applies to. The i18n
runtime, CSR navigation, and HMR all read the block instead of matching
window.__wrnI18n= with a regex.
Pages now render zero executable inline scripts, so an inline script-src
violation is structurally impossible rather than merely unobserved. Zero
framework JavaScript on island-free routes is unaffected: the block is
inert data, and nothing loads to read it unless the page needs it.

hasExecutableSql returns as soon as it meets a quote character, so the quote
variable was assigned and never read: the `if (quote)` branch could never run.
eslint reported it as a useless assignment and the error blocks the release
gate on main. Removing the variable and the unreachable branch keeps behaviour
identical, since encountering a quote already means the SQL is executable.
Also drops an eslint-disable directive in csr's output error reporter that
suppressed nothing.

Pagination reported the requested page only through its change output, so on a
server-rendered page the controls did nothing: the parent had to own client
state to react, and the emitted page never became a URL. An optional
hrefTemplate now renders the steps and page numbers as anchors, which work
before hydration and without JavaScript and give each page a crawlable URL.
Buttons remain the default for client-owned lists. End steps are clamped and
marked disabled rather than linking past the first or last page.
Output handler errors are no longer swallowed. Nothing awaits invokeOutput, so
a handler that threw became an unhandled rejection that never reached the
console and presented as a control that silently does nothing. Handler errors
are now reported as WRN-DEV-OUTPUT-HANDLER-ERROR.
Regenerates the component reference and the UI visual contract.
