server.fn() posts to POST /__wrnexus/rpc. Dev intercepts that path before
handlers.fetch and routes it to a createRpcHandler instance built from
loadWrnServerModule; createProductionServer/createProductionHandlers had no
such route, so the request fell through to the internal-caller-gated
inter-app service RPC and 404'd.
Add resolveProdServerFunctions(), a synchronous equivalent of dev's resolve
that searches the already-statically-imported ProdManifest components/pages/
layouts for __wrnexusServerFunctions + __wrnexusRpcManifest, and wire it into
createProductionHandlers with the same validateCsrf + withServerFnRequestContext
wrapping dev uses. Move those two helpers into a new rpc-shared.ts so prod.ts
can use them without a circular import through index.ts.
Add packages/dev-server/test/prod-server-fn-rpc.test.ts covering a successful
call, CSRF rejection, and clean 404s for an unknown component/function.
Wraps the three additional entry points where user server code runs
outside fetchHandler's own context wrap:
- the server-function RPC path (/__wrnexus/rpc) intercepted before
handlers.fetch in the dev server (index.ts) - what server.fn() travels
- the service RPC path (isRpcPath) inside fetchHandler, which runs
implement()/implementStream() service code before ctx existed
- the HMR-sync handler, which runs real load blocks/actions via dispatch()

The dev server got slower the longer it ran. Measured on the example app:
30 .wrn edits grew RSS from 117 MB to 137 MB and never gave it back, while
30 CSS edits cost nothing -- so the leak is exactly one retained module
identity per rebuild, not caches or file handles.
That is inherent to reloading a module in-process. Bun caches modules by
path, so a rebuild has to be given a new identity to be picked up at all,
and Bun has no API to unload the old one. At roughly 0.66 MB a rebuild, a
long editing session is several hundred megabytes of garbage that cannot
be collected.
The process now recycles itself past a rebuild threshold, exiting with the
RESTART_EXIT_CODE the CLI supervisor already respawns on; browsers
reconnect because the HMR client already retries. It waits for a quiet
period first so a live request is never cut off, and the threshold (300
rebuilds, about 200 MB) sits well above a normal session. Set
WRNEXUS_DEV_RECYCLE_AFTER to tune it, or 0 to switch it off.
Also bounds browserArtifactPaths and islandArtifactPaths, which are keyed
by content hash and so gained an entry per rebuild that was never read
again. Small next to the module leak, but unbounded is unbounded.

The WebSocket origin check compared the browser's Origin host, which
carries the port, against configured domains, which do not. publicOrigin
only ever matches domains[0], so every other domain fell through to that
comparison and was denied purely on the port: web.localhost:3000 never
matched web.localhost.
The result was a 403 on the HMR upgrade and a client reconnecting
forever, while the page itself loaded fine because HTTP routing resolves
the Host separately.
Compares hostnames now. Unrelated and lookalike-suffix origins are still
denied, and both cases are covered by tests.
Verified through a real gateway: the HMR socket opens on both localhost
and web.localhost, and a live edit reaches the browser.

Adds gatewayWebSocketBackendHeaders so proxied upgrades carry application
identity while Bun keeps ownership of WebSocket framing.

The HMR client script was dead in the browser. HMR_CLIENT_JS is a
TypeScript template literal, so the regex [ \t\r\n] inside it was expanded
into real control characters, producing a regex literal containing a raw
newline — a syntax error that took the whole script down with "Invalid
regular expression: missing /". It now uses \s, and a test asserts the
emitted client parses and holds no control characters inside regex
literals; that test fails if the bug is reintroduced.
HMR also corrupted CSP nonces. A document's nonce is fixed at load, but
morph copied attributes from freshly fetched HTML, overwriting the live
nonce with one the browser will not honour. syncAttrs now leaves nonce
alone, and nodes moved across are re-stamped with the live nonce.
Islands vanished on every HMR update: morph puts the server placeholder
back over the mounted island. The island runtime now remounts on
wrnexus:hmr-updated. Remounting swaps the container for a bare clone —
re-rendering the existing root is a no-op once HMR has wiped the DOM
externally, and unmounting throws asynchronously because the nodes React
wants to remove are already gone.

The island pieces existed but nothing connected .wrn compilation to island
emission. Now:
- codegen emits a data-wrn-island placeholder for component tags bound to
.tsx imports, keeping .wrn components on the normal mount path
- the dev pipeline and static build resolve island imports, thread the
names into codegen, and build the bundles
- collectScripts adds /__wrnexus/islands.js only when island markup is
present, so island-free pages still ship nothing
- island routes classify as static-interactive via hasIslands
Three bugs found by driving a real page in the browser:
1. The mount runtime was never built anywhere, so the bootstrap 404'd and
no island mounted.
2. Building the runtime separately from the islands gave each its own copy
of React: "Cannot read properties of null (reading 'useState')". The
runtime is now an entrypoint of the same build so React stays in one
shared chunk. The existing single-React test only compared bundles
within one build and could not see across build boundaries.
3. Island props arrived as attribute strings, so start={3} was "3" and
incrementing produced "31" then "311". Props now follow JSX semantics:
{…} parses as JSON, quoted values stay strings, and a runtime
expression is a WRN-ISLAND-PROPS build error rather than a silent
wrong value.
island-codegen.ts no longer imports @wrnexus/core. Compiler modules are
bundled into the Node-only VS Code extension, which contains no other
packages, so a runtime import of core broke the editor compiler; the two
helpers are implemented locally and the core dependency is dropped again.

- Resolve RPC call origins via a new WRNEXUS_INTERNAL_ORIGINS map (loopback
origins the gateway hands each child before spawning it), falling back to
the public appOrigin only when it is absent. Calls previously always went
to the public gateway origin, which the gateway unconditionally 404s on
the RPC prefix by design — every real cross-app call failed.
- Stop loadServices() from running ahead of routing and stop memoizing a
rejected load: one bad file under app/services/ no longer permanently
breaks every route in the app. A failed load logs loudly, is retried on
the next RPC request, and the RPC path gets a structured RPC_UNKNOWN
instead of an unhandled throw.
- Reject a service whose contract.name does not match the filename it is
mounted under, naming both, instead of silently mounting under the
filename while the typed client calls by contract name.
- Let ServiceError accept an explicit retryable and have the client pass the
wire value through, instead of recomputing (and silently flipping) it from
the error code alone.
- Document the gateway/X-Forwarded-* deployment requirement in the RPC
README.
Each of the three code blockers has a new/extended test that was verified to
fail when its fix was reverted (rpc/test/integration.test.ts,
dev-server/test/rpc-services-loading.test.ts).

Adds examples/auth-showcase/app/services/greeter-client.ts so the showcase
demonstrates both halves - the review noted the example was callee-only, so a
developer had no working reference for making a call.
Raises integration coverage to the planned 3 tests and adds the missing
rpc-endpoint cases. Also wires the prod build path for services.
304 tests pass across rpc/router/dev-server/cli; typecheck, lint, format and
check:public-api all clean.

Critical:
- router: fail loudly (WRN-SERVICE-COLLISION) when two app/services files
scan to the same service name, instead of silently letting directory-walk
order pick a winner.
Important:
- server.ts: wrap a throwing input schema so its raw message cannot escape
invoke(); returns RPC_INVALID and logs server-side instead.
- client.ts: race timeoutMs against transport.call so a stalled transport
cannot hang the caller; rejects with a ServiceError(RPC_TRANSPORT).
- client.ts: the proxy returns undefined for undeclared properties (incl.
then/catch/finally) instead of a function that throws, closing the
await-client thenable trap.
- gateway.ts / rpc-dispatch.ts: import RPC_PATH_PREFIX / RPC_INTERNAL_HEADER
from @wrnexus/rpc instead of hardcoding local copies.
- gateway.test.ts: cover the RPC-prefix edge block and internal-header
stripping across casing variants.
- http.test.ts / client.test.ts: cover anonymous-call header omission, the
internal marker, the retryable-status sweep, network/malformed/HTML
failures, AbortSignal propagation, the timeout path, and timer cleanup.
Minor:
- transport.ts: Object.hasOwn for handler lookup; note the entry-only abort
check.
- client.ts: wrap a missing/invalid WRNEXUS_RPC_SECRET as a ServiceError
(RPC_IDENTITY) instead of a bare Error.
- rpc/package.json: drop the unused @wrnexus/authz dependency.
- server.ts: implement() now throws at construction time if a declared
procedure has no own handler.
Verified: reverting the service-collision check and the client timeout race
each make their new test fail, then restore green.

C1 CRITICAL: implement() looked up procedures/handlers with plain property
indexing, so any Object.prototype member name (constructor, toString, etc.)
resolved truthy and skipped the permission gate entirely. Fixed with
Object.hasOwn checks in packages/rpc/src/server.ts. Defense-in-depth guard
added in packages/dev-server/src/rpc-dispatch.ts constraining URL path
segments to a safe charset before they reach service/procedure lookups.
Added missing direct test coverage for packages/rpc/src/transport.ts,
server.ts and client.ts (previously untested), including a prototype-name
sweep in both server.test.ts and dev-server's rpc-endpoint.test.ts.

Brings the uncommitted body of work under version control so it cannot be
lost. Gates are green: 152 tests pass across rpc/router/dev-server,
typecheck, lint, format and check:public-api all clean.
NOT YET REVIEWED. None of Tasks 5-11 has had an independent task review, and
Task 4's second fix round was never re-reviewed either.
Known gaps against the plan, recorded here rather than discovered later:
- packages/rpc/test/{transport,server,client}.test.ts are ABSENT. The plan
required a test file for each. server.ts holds the fail-closed identity and
permission checks and currently has no direct coverage at all.
- rpc-endpoint.test.ts has 3 tests where the plan specified 9. Missing:
unknown service, non-POST, malformed body, non-rpc passthrough, and the
isInternalCaller sweep. This is the task where a reachable
/__wrnexus/rpc/* makes every permission check in the workspace bypassable.
- http.test.ts has 3 of 7; integration.test.ts 2 of 3;
services-discovery.test.ts 1 of 4.

createProductionHandlers called setAuthzCatalog unconditionally, so a caller
using client.ts's documented escape hatch (setAuthzCatalog(catalog) before
importing anything that reads it) had that catalog silently wiped to empty
whenever opts.authz was omitted. Now only sets when opts.authz has entries to
contribute, or when nothing has been set yet; a non-empty opts.authz still
always sets and still throws on a genuine conflict.
Also removes RuntimeDeps.authz: nothing read it, and its doc comment
described a consumer that doesn't exist. The real wiring is
getAuthzCatalog()/setAuthzCatalog(), including the HMR hot-update path, which
is untouched.

Fix round 2 for Task 14, addressing a critical review finding reproduced on
a real built server.
C1 (critical): the generated production entry set the authz catalog inside
createProductionServer's BODY, but ES modules evaluate every static import
(including app middleware, emitted as a static import) before the importing
module's body runs. Middleware reading getAuthzCatalog() at module scope —
the same eager shape authzMiddleware({ catalog, ... }) itself requires, and
the pattern app/middleware/logger.ts's `export default requestLogger({...})`
already uses — saw an unset catalog and crashed the whole process at import
time, after every other gate (typecheck/lint/tests/a plain `bun run build`)
stayed green.
Fix: packages/cli/src/build.ts now emits a small side-effecting
`.authz-setup.ts` module containing the static imports of every
app/authz/*.ts declaration plus a call to the new
applyAuthzManifestEarly(entries) (packages/dev-server/src/prod.ts), and
imports THAT MODULE FIRST in the generated entry — before pages, api,
realtime, middleware, components, and layouts. applyAuthzManifestEarly is
deliberately silent (no missing-default-export warnings, though a genuine
conflict still throws and fails the boot at import time); createProductionHandlers
keeps its own unconditional merge+set as an idempotent, always-warning second
pass, so an adapter that bypasses the generated entry and calls it directly
still gets a correctly merged, validated catalog, and so the function stays
independently testable.
I3: corrected packages/authz/src/client.ts's WRN-AUTHZ-SETUP message, which
claimed prod always sets the catalog before middleware runs — true again for
the generated entry after the C1 fix, but not for a custom entry that calls
createProductionHandlers directly.
I2: dev HMR editing app/authz/*.ts reloaded the page while the OLD catalog
stayed authoritative (watch.ts classifies any non-CSS change as "server";
hotUpdate had no authz/ branch) — a false security signal, since tightening
or removing a permission looked like it took effect but didn't until a
restart. Added the branch (packages/dev-server/src/index.ts), and gave
loadAppAuthzCatalog (authz-boot.ts) an injectable importer: a raw import()
would have silently no-op'd on the re-import (Bun caches local TS/JS modules
by filesystem path and ignores query strings), so the hot path routes through
loadModule (pipeline.ts) instead, which copies the edited file to a versioned
sibling specifically to defeat that cache.
I4: added direct createProductionHandlers/applyAuthzManifestEarly tests
(packages/dev-server/test/authz-prod.test.ts: conflict throws naming both
files, missing default export warns and skips, empty array yields an empty
catalog, a second call re-validates rather than trusting a stale singleton)
and the regression test that matters most
(packages/cli/test/authz-prod-coldstart.test.ts): a real `runBuild` + a real
`bun dist/server.js` boot, with a middleware module reading
getAuthzCatalog() at module scope, asserting it actually serves a request.
M5: startServer built its own router once, then loadAppAuthzCatalog built a
second one from scratch on every dev boot and every authz/ hot reload.
loadAppAuthzCatalog now accepts either an appDir (still used standalone, e.g.
by the test suite) or an already-built Router, and both call sites in
index.ts now pass the router they already have.
Every fix in this round was verified non-vacuous by sabotaging it and
confirming the corresponding test fails, then reverting.
Fix round 1 for Task 14 — closes the gap flagged in the last report:
loadAppAuthzCatalog existed but nothing called it.
- packages/authz/src/client.ts (new): setAuthzCatalog/getAuthzCatalog/
hasAuthzCatalog, mirroring @wrnexus/db's client.ts. App middleware runs
at module-eval time and needs the catalog then, so ctx cannot carry it;
getAuthzCatalog() throws a setup error naming the fix, like getDb() does.
Exported from packages/authz/src/index.ts.
- packages/dev-server/src/index.ts: startServer calls loadAppAuthzCatalog +
setAuthzCatalog before middleware is resolved (schemasJs precedent),
and populates the new RuntimeDeps.authz field.
- packages/dev-server/src/runtime.ts: RuntimeDeps gains authz?: AuthzCatalog.
- packages/cli/src/build.ts: emits static imports of each app/authz/*.ts
file into the generated entry (components/layouts precedent) and passes
{ source, module } pairs through ProdOptions.authz — the catalog holds
policy functions, so it cannot be JSON-baked like schemasJs.
- packages/dev-server/src/prod.ts: createProductionHandlers merges those
declarations and calls setAuthzCatalog before the server accepts
traffic, so a conflict fails the boot instead of surfacing on the first
request. Runs for every deployment adapter, not only Bun.serve.
The framework never installs authzMiddleware itself; the app still
registers it with its own store.
Verified end-to-end: added a temporary app/authz declaration to
examples/basic-app, ran `bun run build`, inspected the generated entry's
static import + authz array, and booted dist/server.js to confirm the
merge/setAuthzCatalog call succeeds against real bundled code (reverted
before commit).
Adds loadAppAuthzCatalog(appDir) to @wrnexus/dev-server: discovers
app/authz/*.ts declarations via buildRouter, imports and merges them
into an AuthzCatalog, returning an empty catalog when the app has no
declarations. A declaration with no default export is skipped with a
warning; a genuine conflict between two declarations throws
WRN-AUTHZ-CONFLICT naming both source files.
Declared the missing @wrnexus/authz workspace dependency in
dev-server's package.json.
Scan app/authz/<name>.{ts,js} the same way app/schemas is scanned,
exposing Router.authz: ComponentRef[]. Also update the two other
literal Router construction sites (prod runtime, dev-server test
fixture) that now need the new required field.
scanDir gains an optional extraExtensions parameter (default []) so
the authz scan can accept .js files without widening the extension
allow-list used by route scanning (app/pages, app/api, app/realtime),
which would otherwise leak .js into generated route URLs via
fileToRoute.
Audit of 0.8.4 found the repo's own gates green, so these came from manual
review; each is covered by a new regression test.
security/fetch.ts
- safeFetch re-attached Authorization/Cookie on a same-origin redirect that
followed a cross-origin hop (a -> b -> b), handing credentials to the second
host. Compare against the origin the caller trusted, not the previous hop.
- The private-network guard resolved the host, approved it, then let fetch
resolve again, so a low-TTL record could answer public for the check and
private for the connection. Pin the connection to the validated address,
preserving Host and TLS serverName. Opt out with pinDns: false.
- 0:0:0:0:0:ffff:127.0.0.1, ::ffff:7f00:1 and fec0::1 were not treated as
private. Add uncompressed IPv4-mapped forms, site-local IPv6, 198.18/15
and 192.0.0/24.
security/url.ts
- sanitizeUrl returned "//evil.com" verbatim via the relative-path fast path,
bypassing the host checks it had just run; in an href that navigates
cross-origin. Resolve protocol-relative input instead.
dev-server/gateway.ts
- Malformed base64 in an Authorization header threw out of checkAuth on an
unauthenticated path. Fail closed.
- split(":", 2) truncated passwords at the first colon, so a password
containing ":" could never authenticate.
- The credential compare short-circuited on length mismatch, leaking length
by timing. Extracted as verifyBasicAuth so it is testable.
authz/index.ts
- Namespace wildcards only matched the first segment, so "post:comment:*"
did not grant "post:comment:delete". Match at every depth.
uploader/operations.ts
- Validate transcoder dimensions and bitrate rather than trusting the declared
type, and reject ".." path segments.
package.json
- The brace-expansion override pinned 5.0.8, which is inside the advisory
range >=4.0.0 <5.0.9. Bump to 5.0.9; bun audit is now clean.
Verified: check:production passes (typecheck, lint, 1033 tests, format,
ASVS, public-API baseline, editor checks).
