 ## Overview

 UCE is a PHP-inspired server-side runtime that lets you build web pages and handlers in C++ using a small `.uce` preprocessor plus a FastCGI application server.

- `.uce` pages compile to shared objects on demand
+- `.uce` pages compile to WebAssembly side modules on demand
 - normal HTTP pages expose `RENDER(Request& context)`
 - WebSocket pages can additionally expose `WS(Request& context)`
- sub-rendering and components pass structured data through `context.call`
- nginx can forward normal `.uce` requests and ordinary `.ws.uce` page loads to the FastCGI socket, while real WebSocket upgrade requests for `.ws.uce` endpoints go to the built-in HTTP/WebSocket listener
- the nginx-published application tree now lives under `site/`
+- local CLI/admin/test entrypoints can expose `CLI(Request& context)` and are invoked through the Unix CLI socket
+- sub-rendering and components pass structured data through `context.props`
+- nginx can forward normal `.uce` requests to the FastCGI socket, while WebSocket upgrade requests for `.uce` endpoints go to the built-in HTTP/WebSocket listener
+- the example application tree lives under `site/`; deployments should publish app files to a normal web root such as `/var/www/html`
 - you can include C++ code as much as you want, but only .uce files called via API functions and entry points will be pre-processed
 - the preprocessor has two jobs:
       - allow for inline HTML within C++ and the use of templating tags inside of that HTML

 - `RENDER(Request& context)` for normal HTTP rendering
 - `WS(Request& context)` for inbound WebSocket messages
+- `CLI(Request& context)` for local command-line/admin/test invocations through `CLI_SOCKET_PATH`

 Useful related runtime patterns:

 - `context.cfg` for request-local structured configuration
- `context.call` for invocation or message-local structured input

 - `context.connection` for broker-owned per-WebSocket-connection state shared across `WS(Request& context)` calls
+- `context.params["UCE_CLI"] == "1"` while handling a local CLI socket request
+- `context.in` for the current request body, including the current WebSocket message payload inside `WS(Request& context)`
+- `context.params["WS_..."]` for direct WebSocket message metadata on the request parameter map
 - `context.params`, `context.get`, `context.post`, `context.cookies`, `context.session`, and `context.header` for request/response state

 - `ascii_safe_name(String)` for conservative ASCII identifier normalization
 - `path_join(base, child)` for filesystem-style path assembly

+wasm runtime: central WS broker, unified handlers, W7d holdouts, membrane completeness
+
+- WS: a dedicated broker process owns HTTP_PORT + every connection; it forwards
+  renders to the worker pool over uce.sock (non-blocking) and applies ws_*
+  command batches flushed back at workspace teardown. Removes the now-dead
+  per-worker websocket executor (-509 lines).
+- Dispatch: unify CLI / WebSocket / serve_http / page render through one
+  serve_via_wasm(entry_unit, handler) path; handler string -> __uce_<handler>
+  export symbol.
+- W7d: rewrite zip.uce to the membrane return-value error contract (no C++
+  try/catch), error-reporting.uce to genuine wasm traps instead of throw, and
+  sharedunit.uce to unit_info(); empty the native-only token gate.
+- Membrane: wire ls / mkdir / file_mtime through new uce_host_file_list /
+  uce_host_file_mkdir / uce_host_file_mtime hostcalls (resolve_guest_file gains
+  directory support). Fixes /doc/index.uce listing nothing; adds a regression
+  assertion that the index enumerates items.
+- Docs: add docs/wasm-runtime-architecture.md; record the W7e staged native-
+  deletion plan in WASM-PROPOSAL.md.
+
+
+commit 2debd338040cf97e82bb8ccbb5ec09caee089c17
+W7e: wasm-preferred dispatch + compile-on-demand; harden unit ABI validator
+
+- Dispatch (linux_fastcgi.cpp): route every request through wasm. On a
+  cold/stale artifact, compile the unit on demand (get_shared_unit, forced) and
+  serve wasm; native compiler_invoke* remains only as a fallback when wasm
+  cannot be made ready (compile failure / backend disabled). Applies to the 4
+  handle_complete branches and the CLI socket path.
+- backend.cpp: delete the now-vestigial native-only fallback token gate
+  (wasm_backend_native_fallback_*), empty since W7d; should_handle now gates on
+  config + current artifact + healthy worker only.
+- check_unit_wasm.py: skip the defense-in-depth llvm-nm allocator scan when
+  llvm-nm SIGSEGVs on a degenerate-but-valid module (e.g. a unit with no
+  exported handlers). Fixes site/demo/empty.uce, the last unit that could not
+  produce a .wasm; forbidden allocator *exports* are still rejected.
+
+A pi-assisted review caught that the compile-freshness check keys off the .so
+mtime only, so force_recompile is required to rebuild a missing/stale .wasm; a
+unit already cached in-process whose .wasm later vanished still uses native
+fallback (closed in W7e stage B). Native execution is otherwise bypassed for
+all real traffic.
+
+
+commit fb728d63bcd0d80bd5161537e81c30d27eb4df7b
+W7e stage B: factor the .wasm artifact into unit compile-freshness
+
+inspect_shared_unit_filesystem() tracked only the .so mtime, so a missing or
+stale .wasm with a current .so never triggered a rebuild and the unit fell to
+native indefinitely (the in-process cache also never invalidated). Account for
+su->wasm_name when wasm unit compilation is enabled: a unit counts as compiled
+only as of the OLDER of the two artifacts; a missing .wasm forces a recompile.
+Closes the cached-vanished-.wasm gap noted in the stage A review.
+
+
+commit cf513368730e5f337e64a9c9f1456e6a64f49d9c
+W7e: delete the native unit pipeline (.so compile + dlopen execution)
+
+Units now run exclusively on wasm; the native generated-C++ -> clang -> .so ->
+dlopen path and its request-time fallback are removed.
+
+- Dispatch (linux_fastcgi.cpp): the 4 handle_complete branches + the CLI-socket
+  path route every request through wasm (wasm_ready compiles cold/stale on
+  demand); a wasm-unavailable unit now yields a clean error page
+  (fail_wasm_unavailable / render_request_failure) instead of native execution.
+  compiler_invoke / _cli / _websocket / _serve_http deleted.
+- compiler.cpp (-1274): removed the native .so compile (COMPILE_SCRIPT),
+  load_shared_unit, dlopen/dlsym/dlclose, compiler_load_shared_unit, and the
+  SharedUnit .so function-pointer fields (on_setup/on_render/on_component/
+  on_websocket/on_cli/on_once/on_init) in types.h/types.cpp. compile_shared_unit
+  now builds only the .wasm side-module; the .uce preprocessor/parser front-end
+  is kept (it emits the C++ the wasm compile consumes).
+- unit_call()/component()/once/init now resolve across units through the wasm
+  host component resolver (uce_host_component_resolve) instead of native dlsym;
+  configured runtime error pages render through the wasm backend.
+- Dropped the WASM_BACKEND_ENABLED feature flag and dead COMPILE_SCRIPT /
+  COMPILE_WASM_UNITS config; unit ABI freshness tied to UCE_UNIT_ABI_VERSION;
+  guard against serving a stale .wasm for a deleted source; retired the obsolete
+  W5 native-vs-wasm toggle script. Docs updated.
+
+
+commit bfd6d338299dd9001fe2d4a66f82bbc2b3b07ed9
+W7f: sweep dead/legacy/fallback leftovers after native-pipeline removal
+
+Post-deletion cleanup (units run only on wasm):
+- types.h/compiler.cpp: drop the native-era SharedUnit fields so_name,
+  bin_file_name, and the opt_so_optional cache-mode plumbing (no native
+  optional .so path remains). The per-unit compile lock is re-keyed from
+  so_name+.lock to wasm_name+.lock (still per-unit).
+- unit_info() and to_string(SharedUnit*) no longer expose .so artifact fields.
+- backend.h: drop the stale "+ fallback-token gate" comment.
+- Docs/comments corrected to wasm-only reality: README, tests/README,
+  site/doc C++ preprocessor + error_pages + unit_info pages, site/info intro,
+  site/demo/unit-browser artifact card; the Phase-5 native-vs-wasm benchmark
+  harness (tests/wasm_benchmark.py) reframed for the wasm-only backend.
+
+Audit confirmed no live references remain to so_handle, load_shared_unit,
+compiler_load_shared_unit, compiler_invoke*/_cli/_websocket/_serve_http,
+COMPILE_SCRIPT/COMPILE_WASM_UNITS, or the native export-symbol constants;
+request_ref_handler/dv_call_handler are kept (live wasm funcref casts).

+perf: cache the compiled core module so fresh workers deserialize, not recompile
+
+Workers recycle every 8 requests (calls_until_termination=8). Each fresh worker
+ran wasmtime::Module::compile() on the 6.8MB bin/wasm/core.wasm — a ~1.3s
+Cranelift JIT — on its first request, so every ~8th request spiked to ~1.3s and
+dominated suite wall-clock.
+
+Cache the compiled artifact: on worker core-module load, if bin/wasm/core.cwasm
+exists and is newer than core.wasm, load it via Module::deserialize_file() (mmap,
+~ms); otherwise Module::compile() as before and atomically (temp+rename) write
+the serialized artifact for the next worker. Deserialize failure / stale cache
+falls back to a normal compile, so it is self-healing; rebuilding core.wasm
+(newer mtime) invalidates the cache. Engine config (epoch_interruption,
+signals_based_traps(false)) is unchanged, which the serialized format requires.
+
+
+commit 83ab9e10f7c0f17805e40a9a3d2b4a3357e5280f
+perf: extend the compiled-module disk cache to per-unit modules
+
+Follow-up to 560290c. Per-unit .wasm modules were still Cranelift-compiled per
+worker on first use (~40-70ms each), so with 8-call worker recycling fresh
+workers re-JIT every unit they touch.
+
+Refactor the core cache logic into a shared WasmWorker helper:
+- cached_wasm_path(p): maps <...>.wasm -> <...>.cwasm.
+- load_or_compile_cached_module(engine, cached, wasm, bytes, err): deserialize_file
+  the .cwasm when it is newer than the .wasm; otherwise Module::compile + serialize,
+  written atomically (temp+rename); deserialize failure falls back to compile.
+Both the core module load and unit_module() now go through this helper, so unit
+artifacts get the same <unit>.uce.cwasm cache the core got.

+
+commit 4f84ac544d9c91a66d068d372055eec8e1723def
+feat: request_perf() worker-side timing hostcall; restore demo System Info
+
+Units run in the wasm sandbox, so my_pid/parent_pid/context.server->request_count
+read as sandbox stubs — the demo System Info counters were broken, and there was
+no authoritative server-side request timing available to unit code (client-side
+measurement cannot see queue/dispatch latency).
+
+Add a request_perf() unit API backed by a new uce_host_request_perf hostcall.
+The native worker answers it live, returning a DValue:
+  worker_pid, parent_pid, request_count,
+  accept_us  = (time_start - time_init)*1e6   (entry -> dispatch wait),
+  running_us = (now - time_start)*1e6         (since dispatch, live),
+  total_us   = (now - time_init)*1e6          (since the request entered UCE),
+  workspace_birth_us.
+time_init is captured at request entry (handle_request, with a handle_complete
+fallback); a RequestPerfSnapshot {pids, request_count, time_init, time_start} is
+threaded from wasm_backend_serve through wasm_worker_serve onto the workspace,
+and the hostcall computes the live deltas at call time. Wired like uce_host_units
+(sized DValue hostcall): core_hostcalls.syms + sys.cpp/sys.h request_perf().
+
+site/demo/index.uce System Info now uses request_perf() and shows the real worker
+PID, an incrementing per-worker request count, and the timing counters.

+# UCE Runtime Setup
+
+This guide describes how to run UCE behind nginx or Apache. UCE is a FastCGI application server for `.uce` units; the web server should serve static files directly and forward dynamic `.uce` requests to the UCE runtime.
+
+## Deployment shape
+
+A typical deployment has four pieces:
+
+1. A checked-out or packaged UCE runtime tree.
+2. `/etc/uce/settings.cfg`, read by the UCE runtime at startup.
+3. `uce.service`, a systemd service that builds/starts/restarts the runtime.
+4. nginx or Apache as the public HTTP server.
+
+Recommended filesystem layout for a source checkout:
+
+```text
+/opt/uce/                         UCE repository/runtime root
+/var/www/html/                    public web root served by nginx/Apache
+/etc/uce/settings.cfg             runtime configuration
+/run/uce/fastcgi.sock             FastCGI socket used by nginx/Apache
+/run/uce/cli.sock                 local CLI/admin/test socket
+/var/cache/uce/work               generated source, wasm modules, caches
+/var/lib/uce/uploads              multipart upload scratch space
+/var/lib/uce/sessions             session files
+```
+
+For packaged installs, the runtime may live under `/usr/lib/uce` instead of `/opt/uce`. Keep the public web root at `/var/www/html` or another normal web-root path, not under the runtime source tree.
+
+## Build requirements
+
+On Debian/Ubuntu-like systems, install the distro packages first:
+
+```bash
+apt update
+apt install -y clang build-essential libpcre2-dev mariadb-client libmariadb-dev curl rsync ca-certificates
+```
+
+UCE also requires two non-vendored dependencies. WASI SDK is load-bearing at runtime because UCE compiles units on demand during requests and during proactive startup scans.
+
+- **Wasmtime C API / C++ headers** at `/opt/wasmtime` by default. `scripts/build_linux.sh` expects:
+  - `/opt/wasmtime/include/wasmtime.hh`
+  - `/opt/wasmtime/include/wasmtime/*.h`
+  - `/opt/wasmtime/lib/libwasmtime.so`
+
+- **Pinned WASI SDK** at `/opt/wasi-sdk` by default. `scripts/build_core_wasm.sh` and request-time `scripts/compile_wasm_unit` expect:
+  - `/opt/wasi-sdk/bin/clang++`
+  - `/opt/wasi-sdk/bin/wasm-ld`
+  - `/opt/wasi-sdk/bin/llvm-objcopy`
+
+You can use different install locations by setting environment variables before building and in the systemd service environment:
+
+```bash
+export WASMTIME_HOME=/path/to/wasmtime
+export WASI_SDK=/path/to/wasi-sdk
+```
+
+Install one web server:
+
+```bash
+apt install -y nginx
+# or
+apt install -y apache2
+```
+
+Build UCE from the repository root:
+
+```bash
+cd /opt/uce
+bash scripts/build_core_wasm.sh
+bash scripts/build_linux.sh
+```
+
+Publish the starter site or your application files into the web root:
+
+```bash
+mkdir -p /var/www/html
+rsync -a site/ /var/www/html/
+```
+
+The main binary is written to:
+
+```text
+bin/uce_fastcgi.linux.bin
+```
+
+### Installing Wasmtime and WASI SDK
+
+The UCE build does not download these dependencies for you. Install Wasmtime through a compatible distro package or a pinned upstream C API archive. Install WASI SDK with UCE's pinned installer, or unpack the same pinned archive under `/opt/wasi-sdk`.
+
+Do not use `curl | sh` installers in production setup scripts. Download archives from the upstream release pages, verify checksums/signatures when available, and record the exact versions in your deployment notes. Avoid installing a release published in the last few days unless you have reviewed it separately.
+
+The expected directories are:
+
+```text
+/opt/wasmtime/include/wasmtime.hh
+/opt/wasmtime/include/wasmtime/store.h
+/opt/wasmtime/lib/libwasmtime.so
+
+/opt/wasi-sdk/bin/clang++
+/opt/wasi-sdk/bin/wasm-ld
+/opt/wasi-sdk/bin/llvm-objcopy
+```
+
+Install the WASI SDK:
+
+```bash
+cd /opt/uce
+scripts/install_wasi_sdk.sh
+scripts/install_wasi_sdk.sh --check-only
+```
+
+The current pin is documented in `docs/wasi-sdk-toolchain.md`. The script verifies the archive SHA256 before installing and updates `/opt/wasi-sdk` to point at the pinned versioned directory.
+
+For Wasmtime, use a compatible distro package or an upstream C API archive. Example flow using an archive you have already chosen and verified:
+
+```bash
+mkdir -p /opt /tmp/uce-deps
+cd /tmp/uce-deps
+
+# Download the Wasmtime C API archive for your architecture from the upstream
+# release page, then verify its checksum before unpacking. The archive name
+# normally contains "c-api".
+sha256sum -c wasmtime-c-api.sha256
+mkdir -p /opt/wasmtime
+tar -xf wasmtime-*-c-api*.tar.* -C /opt/wasmtime --strip-components=1
+```
+
+After unpacking, verify the tools UCE needs. Also record the exact Wasmtime and WASI SDK versions used. The native build embeds an rpath for `$WASMTIME_HOME/lib`, so the service environment should use the same `WASMTIME_HOME` value used during build.
+
+```bash
+test -f /opt/wasmtime/include/wasmtime.hh
+test -f /opt/wasmtime/lib/libwasmtime.so
+/opt/wasi-sdk/bin/clang++ --version
+/opt/wasi-sdk/bin/wasm-ld --version
+/opt/wasi-sdk/bin/llvm-objcopy --version
+```
+
+If your paths differ, export the variables for manual builds:
+
+```bash
+WASMTIME_HOME=/usr/local/wasmtime WASI_SDK=/usr/local/wasi-sdk bash scripts/build_core_wasm.sh
+WASMTIME_HOME=/usr/local/wasmtime WASI_SDK=/usr/local/wasi-sdk bash scripts/build_linux.sh
+```
+
+For systemd, add an override:

+```
+
+```ini
+[Service]
+Environment=WASMTIME_HOME=/usr/local/wasmtime

+
+Then reload and restart:
+
+```bash
+systemctl daemon-reload
+systemctl restart uce.service

+
+## Runtime configuration
+
+Create `/etc/uce/settings.cfg` from `etc/uce/settings.cfg` and adjust paths if your runtime is not under `/opt/uce`. Replace any checkout-specific paths such as `WASM_CORE_PATH` with `/opt/uce/bin/wasm/core.wasm` or your actual runtime path.
+
+Minimum useful settings:
+
+```ini
+BIN_DIRECTORY=/var/cache/uce/work
+TMP_UPLOAD_PATH=/var/lib/uce/uploads
+SESSION_PATH=/var/lib/uce/sessions
+
+FCGI_SOCKET_PATH=/run/uce/fastcgi.sock
+CLI_SOCKET_PATH=/run/uce/cli.sock
+
+SITE_DIRECTORY=/var/www/html
+HTTP_DOCUMENT_ROOT=/var/www/html
+JIT_COMPILE_ON_REQUEST=1
+PROACTIVE_COMPILE_ENABLED=1
+PROACTIVE_COMPILE_CHECK_INTERVAL=60

+WORKER_COUNT=4
+MAX_MEMORY=16777216
+SESSION_TIME=2592000
+
+HTTP_PORT=8080
+```
+
+Important settings:
+
+- `FCGI_SOCKET_PATH` is the Unix socket used for normal `.uce` requests. Set it explicitly and keep this value and the web-server `fastcgi_pass` path identical. The reference config uses `/run/uce/fastcgi.sock`; if you choose `/run/uce.sock`, use it in both places.
+- `CLI_SOCKET_PATH` is a local HTTP-over-Unix socket used by `scripts/uce-cli` and test/admin units.
+- `SITE_DIRECTORY` is the public site tree to scan for `.uce` files. Use `/var/www/html` when the web root is outside the runtime tree; relative paths are resolved from the runtime working directory.
+- `HTTP_DOCUMENT_ROOT` is the root used by the built-in HTTP/WebSocket listener when it resolves upgrade requests. Set it to the same web root as nginx/Apache.
+- `BIN_DIRECTORY` stores generated C++, wasm artifacts, compile output, and runtime caches.
+- `TMP_UPLOAD_PATH` and `SESSION_PATH` must be writable by the runtime.
+- `HTTP_PORT` is the built-in HTTP/WebSocket listener used for WebSocket upgrade traffic and direct local probes. Bind/firewall it for local access only; nginx/Apache should be the public entry point.
+- `WASM_COMPILE_SCRIPT` must point to `scripts/compile_wasm_unit` unless you provide an equivalent compiler. Relative paths are resolved from the runtime root/`COMPILER_SYS_PATH`. That script calls `scripts/check_unit_wasm.py` after linking each unit and uses the pinned WASI SDK on every deployment host.
+- `WASM_CORE_PATH` must point at the built `core.wasm` file.
+
+After editing settings, restart UCE:
+
+```bash
+systemctl restart uce.service
+```
+
+## systemd service
+
+For source-checkout deployments, install the provided service helper:
+
+```bash
+cd /opt/uce
+scripts/systemd/manage-uce-service.sh setup
+```
+
+That helper installs `scripts/systemd/uce.service`, creates runtime directories, enables the service, and starts it.
+
+Useful commands:
+
+```bash
+scripts/systemd/manage-uce-service.sh status
+scripts/systemd/manage-uce-service.sh restart
+scripts/systemd/manage-uce-service.sh logs 200
+```

+
+### Debian package build
+
+To build a Debian package from the repository root:
+
+```bash
+bash scripts/make_deb.sh 0.1.2
+```
+
+The Debian package creator bundles WASI SDK and Wasmtime by default when `/opt/wasi-sdk` and `/opt/wasmtime` are present. Verify the pinned SDK before building:
+
+```bash
+scripts/install_wasi_sdk.sh --check-only
+bash scripts/make_deb.sh 0.1.2
+```
+
+This includes the resolved `/opt/wasi-sdk-...` tree, `/opt/wasi-sdk` symlink, resolved `/opt/wasmtime-...` tree, and `/opt/wasmtime` symlink in the package. It makes the package large, but keeps request-time unit compilation and runtime linking tied to the toolchain versions that passed the test suite. Set `UCE_DEB_BUNDLE_WASI_SDK=0` or `UCE_DEB_BUNDLE_WASMTIME=0` only if your deployment provides those exact dependencies separately.
+
+### RPM package build
+
+To build an RPM package from the repository root, install `rpmbuild` on the packaging host, verify the pinned SDK, then run:
+
+```bash
+scripts/install_wasi_sdk.sh --check-only
+bash scripts/make_rpm.sh 0.1.2
+```
+
+The RPM creator mirrors the Debian package layout: runtime files under `/usr/lib/uce`, public files under `/var/www/html`, config under `/etc/uce/settings.cfg`, systemd unit under `/usr/lib/systemd/system/uce.service`, and bundled `/opt/wasi-sdk` plus `/opt/wasmtime` trees by default. Set `UCE_RPM_BUNDLE_WASI_SDK=0` or `UCE_RPM_BUNDLE_WASMTIME=0` only if your deployment provides those exact dependencies separately.
+
+## How request routing works
+
+### Static files
+
+The web server should serve ordinary static files directly from the public web root, for example `/var/www/html`.
+
+Examples:
+
+```text
+/style.css
+/images/logo.png
+/examples/uce-starter/js/site.js
+```
+
+These should not touch the UCE runtime.
+
+### Normal `.uce` page requests
+
+For a request such as:
+
+```text
+GET /doc/index.uce?p=component
+```
+
+nginx/Apache forwards the request to `FCGI_SOCKET_PATH` as FastCGI. The web server must provide CGI/FastCGI variables including:
+
+- `SCRIPT_FILENAME` — full filesystem path to the `.uce` file.
+- `DOCUMENT_ROOT` — public web root, normally `/var/www/html` or whatever nginx/Apache uses as `root`/`DocumentRoot`.
+- `SCRIPT_NAME` — URL path to the script, such as `/doc/index.uce`.
+- `DOCUMENT_URI` — normalized URI path without query string.
+- `REQUEST_URI` — original request URI including query string.
+- standard request variables such as method, query string, content type, body length, cookies, and headers.
+
+UCE resolves the unit, compiles it to wasm if needed, creates a request workspace, and calls:
+
+```cpp
+RENDER(Request& context)
+```
+
+The unit writes output with template literals or `print()`. Response headers and status are set through `context.header` and `context.set_status()`.
+
+### Component and sub-render calls
+
+Inside a request, UCE code can call other units:
+
+```cpp
+component("components/card", props, context);
+unit_render("other-page.uce", context);
+```
+
+These calls stay inside the UCE runtime. They are not new HTTP requests and do not go back through nginx or Apache.
+
+### WebSocket pages
+
+Any `.uce` unit can provide both an ordinary page render and WebSocket message handling:
+
+```cpp
+RENDER(Request& context) { ... }  // normal page load
+WS(Request& context) { ... }      // later WebSocket messages
+```
+
+The nginx and Apache examples below split traffic by checking for a WebSocket upgrade request on `.uce` paths. A file such as `chat.uce` or `events.uce` can expose `WS(Request& context)`.
+
+Routing split:
+
+- Plain `GET /demo/chat.uce` should use FastCGI, just like any other page render.
+- WebSocket upgrade requests for `/demo/chat.uce` should proxy to the UCE built-in HTTP/WebSocket listener at `HTTP_PORT`.
+
+The built-in listener owns the socket lifecycle. When a message arrives, the broker forwards a render-style invocation back to the worker pool so `WS(Request& context)` runs inside the same wasm runtime model as normal pages.
+
+### CLI requests
+
+`CLI(Request& context)` handlers are not public web endpoints. They are invoked over `CLI_SOCKET_PATH`:
+
+```bash
+scripts/uce-cli /tests/cli.uce action=echo message=hello
+curl --unix-socket /run/uce/cli.sock http://localhost/tests/cli.uce
+```
+
+Use CLI units for local tests, admin commands, and maintenance tools. Do not expose the CLI socket through nginx or Apache.
+
+### Custom runtime HTTP servers
+
+UCE code can start local custom HTTP listeners with `server_start_http()`. Those are runtime-managed listeners for app-specific local services. They are separate from the public nginx/Apache entry point and should be firewalled or bound locally unless you explicitly want them reachable.
+
+## nginx configuration
+
+### Required modules
+
+A normal nginx build includes the needed FastCGI and proxy modules. Confirm nginx is installed and can load your config:
+
+```bash
+nginx -t
+```
+
+### WebSocket upgrade map
+
+Put this in the nginx `http` block if using WebSockets:
+
+```nginx
+map $http_upgrade $connection_upgrade {
+    default upgrade;
+    ''      close;
+}
+```
+
+### Server block
+
+Example site config:
+
+```nginx
+server {
+    listen 80;
+    server_name example.com;
+
+    root /var/www/html;
+    index index.uce index.html;
+
+    # Serve static files directly. Directory requests use index.uce when present.
+    location / {
+        try_files $uri $uri/ =404;
+    }
+
+    # UCE page requests use FastCGI. If the client asks to upgrade a .uce
+    # request to WebSocket, send that connection to the built-in listener.
+    location ~ \.uce$ {
+        error_page 418 = @uce_websocket;
+        if ($http_upgrade = "websocket") {
+            return 418;
+        }
+
+        include fastcgi_params;
+        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
+        fastcgi_param DOCUMENT_ROOT $document_root;
+        fastcgi_param SCRIPT_NAME $fastcgi_script_name;
+        fastcgi_param DOCUMENT_URI $uri;
+        fastcgi_param REQUEST_URI $request_uri;
+        fastcgi_pass unix:/run/uce/fastcgi.sock;
+    }
+
+    location @uce_websocket {
+        proxy_http_version 1.1;
+        proxy_set_header Host $host;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection $connection_upgrade;
+        proxy_pass http://127.0.0.1:8080;
+    }
+
+    # Defense in depth if the root is changed later.
+    location ~ ^/(src|scripts|etc|bin|work|dist|pkg|docs|changelog)/ {
+        return 404;
+    }
+}
+```
+
+Notes:
+
+- `fastcgi_pass` must match `FCGI_SOCKET_PATH`.
+- `proxy_pass` must match `HTTP_PORT`.
+- The example routes WebSocket upgrades for `.uce` paths to the HTTP/WebSocket listener.
+- The built-in HTTP/WebSocket listener resolves scripts from `HTTP_DOCUMENT_ROOT`; do not depend on client-supplied or proxied `Script-Filename` headers for routing.
+- Ordinary `.uce` page loads continue to use FastCGI.
+- Keep `root` pointed at `/var/www/html`, not the runtime repository root.
+- If your app uses a front controller, replace `location /` with a `try_files` rule that ends at `/index.uce`.
+
+Front-controller variant:
+
+```nginx
+location / {
+    try_files $uri $uri/ /index.uce?$query_string;
+}
+```
+
+Reload nginx:
+
+```bash
+nginx -t
+systemctl reload nginx
+```
+
+## Apache configuration
+
+Apache can run UCE through `mod_proxy_fcgi` for FastCGI and `mod_proxy_wstunnel` or `mod_proxy_http` for WebSocket upgrades.
+
+### Enable modules
+
+On Debian/Ubuntu:
+
+```bash
+a2enmod proxy proxy_fcgi proxy_http proxy_wstunnel rewrite headers setenvif
+systemctl restart apache2
+```
+
+### VirtualHost example
+
+```apache
+<VirtualHost *:80>
+    ServerName example.com
+    DocumentRoot /var/www/html
+
+    <Directory /var/www/html>
+        Require all granted
+        Options FollowSymLinks
+        AllowOverride None
+        DirectoryIndex index.uce index.html
+    </Directory>
+
+    # Do not expose repository internals if DocumentRoot changes later.
+    <LocationMatch "^/(src|scripts|etc|bin|work|dist|pkg|docs|changelog)/">
+        Require all denied
+    </LocationMatch>
+
+    RewriteEngine On
+
+    # WebSocket upgrade traffic for any .uce unit goes to UCE's built-in HTTP listener.
+    RewriteCond %{HTTP:Upgrade} =websocket [NC]
+    RewriteCond %{REQUEST_URI} \.uce(?:\?|$) [NC]
+    RewriteRule ^/(.*)$ ws://127.0.0.1:8080/$1 [P,L]
+
+    # Normal .uce page loads go to FastCGI.
+    <FilesMatch "\.uce$">
+        SetHandler "proxy:unix:/run/uce/fastcgi.sock|fcgi://localhost/"
+    </FilesMatch>
+
+    # Optional: make the key CGI variables explicit for UCE.
+    ProxyFCGISetEnvIf "true" DOCUMENT_ROOT "/var/www/html"
+    ProxyFCGISetEnvIf "true" DOCUMENT_URI "%{REQUEST_URI}"
+</VirtualHost>
+```
+
+Apache notes:
+
+- `SetHandler "proxy:unix:/run/uce/fastcgi.sock|fcgi://localhost/"` must use the same socket path as `FCGI_SOCKET_PATH`.
+- The WebSocket rewrite rule must run before the FastCGI handler.
+- Plain `.uce` page loads should not be proxied as WebSockets unless the client sends `Upgrade: websocket`.
+- Apache's FastCGI environment differs by version and module configuration. If UCE cannot resolve a page, inspect the request environment and make sure `SCRIPT_FILENAME` points to the target file under the web root.
+
+If your Apache version does not populate `SCRIPT_FILENAME` correctly through `SetHandler`, use `ProxyPassMatch` for `.uce` files instead:
+
+```apache
+ProxyPassMatch ^/(.*\.uce)$ unix:/run/uce/fastcgi.sock|fcgi://localhost/var/www/html/$1
+```
+
+Use only one FastCGI mapping style at a time (`SetHandler` or `ProxyPassMatch`) to avoid duplicate routing.
+
+## Permissions
+
+The web server needs permission to connect to `/run/uce/fastcgi.sock`. Common approaches:
+
+- run UCE and the web server under compatible groups;
+- add the web server user (`www-data` on Debian/Ubuntu) to the socket's group;
+- adjust the service or runtime socket mode if needed.
+
+The runtime creates the FastCGI socket and CLI socket under `/run/uce`. The CLI socket should remain local-only and should not be reachable from the public web server.
+
+Writable paths for the runtime:
+
+```text
+/var/cache/uce/work
+/var/lib/uce/uploads
+/var/lib/uce/sessions
+/run/uce
+```
+
+## Verification
+
+Check service state:
+
+```bash
+systemctl status uce.service
+journalctl -u uce.service -n 100 --no-pager
+```
+
+Check the FastCGI/web-server path:
+
+```bash
+curl -i http://127.0.0.1/doc/index.uce -H 'Host: example.com'
+curl -i http://127.0.0.1/examples/uce-starter/ -H 'Host: example.com'
+```
+
+Check the local CLI path:
+
+```bash
+cd /opt/uce
+scripts/uce-cli /tests/cli.uce action=echo message=hello
+scripts/run_cli_tests.sh
+```
+
+Check WebSocket routing with a WebSocket client against a `.uce` endpoint that defines `WS(Request& context)` through nginx/Apache, not directly against `HTTP_PORT`:
+
+```bash
+python3 - <<'PY'
+import base64, os, socket
+host = "example.com"
+path = "/chat.uce"
+key = base64.b64encode(os.urandom(16)).decode()
+request = (
+    f"GET {path} HTTP/1.1\r\n"
+    f"Host: {host}\r\n"
+    "Upgrade: websocket\r\n"
+    "Connection: Upgrade\r\n"
+    f"Sec-WebSocket-Key: {key}\r\n"
+    "Sec-WebSocket-Version: 13\r\n\r\n"
+).encode()
+sock = socket.create_connection(("127.0.0.1", 80), timeout=5)
+sock.sendall(request)
+print(sock.recv(4096).decode("latin1", "replace").split("\r\n", 1)[0])
+sock.close()
+PY
+```
+
+## Operational footguns
+
+- Keep the FastCGI socket path consistent: `FCGI_SOCKET_PATH` and the web-server `fastcgi_pass` must match exactly. The reference config uses `/run/uce/fastcgi.sock`; if you choose `/run/uce.sock`, use it in both places.
+- Keep the public web root separate from the runtime source tree. The examples use `/opt/uce` for runtime files and `/var/www/html` for public files.
+- Set `HTTP_DOCUMENT_ROOT` when the web root is outside the runtime working directory. The built-in HTTP/WebSocket listener resolves upgrade paths from this setting.
+- Do not expose `CLI_SOCKET_PATH` or `HTTP_PORT` as public entry points. The public path should be nginx/Apache.
+- Do not trust `Script-Filename` request headers from direct HTTP clients. The built-in HTTP listener resolves from `HTTP_DOCUMENT_ROOT` and rejects `..` path segments.
+- WASI SDK is a deployment/runtime dependency, not just a developer build tool. UCE compiles units to wasm on demand during requests and during proactive startup scans, so each host must use the pinned SDK version documented in `docs/wasi-sdk-toolchain.md`.
+- After toolchain or compile-script fixes, clear stale failed artifacts under `BIN_DIRECTORY`; otherwise a later request may report an old compile failure.
+
+## Troubleshooting
+
+### 502 Bad Gateway
+
+Check:
+
+- `systemctl status uce.service`
+- `journalctl -u uce.service -n 200 --no-pager`
+- socket path in web server config equals `FCGI_SOCKET_PATH`
+- web server user can connect to the Unix socket
+- `SCRIPT_FILENAME` resolves to an existing `.uce` file
+
+### Raw `.uce` source is downloaded or displayed
+
+The `.uce` request did not match the FastCGI rule. Check location/order rules and confirm the public root is `/var/www/html` or your chosen web-root path.
+
+### Static files 404
+
+Confirm the web server `root`/`DocumentRoot` is `/var/www/html` or your chosen web-root path and that `location /` or Apache directory rules allow static file reads.
+
+### WebSocket page renders but upgrade fails
+
+Check:
+
+- the client sends `Upgrade: websocket`
+- `.uce` upgrade traffic reaches `HTTP_PORT`
+- nginx/Apache preserves `Upgrade` and `Connection` headers
+- `HTTP_DOCUMENT_ROOT` matches the web-server root; if it points at the runtime tree while files live in `/var/www/html`, the built-in listener will return `404 script not found`
+- firewall/network policy allows localhost access to `HTTP_PORT`
+
+### Page compiles fail
+
+Check the compile artifact paths shown in the UCE error response and service logs. Generated files and compile output live under `BIN_DIRECTORY`.
+
+Common compile footguns:
+
+- `WASM_COMPILE_SCRIPT` is unset or points at a removed script such as `scripts/compile`; set it to `scripts/compile_wasm_unit`.
+- `scripts/check_unit_wasm.py` is missing or not executable; `scripts/compile_wasm_unit` calls it after linking each unit.
+- `WASI_SDK` does not point at the pinned tree with `clang++`, `wasm-ld`, `llvm-objcopy`, and `llvm-nm`; run `scripts/install_wasi_sdk.sh --check-only`.
+- `WASMTIME_HOME` does not point at a tree with Wasmtime headers and `libwasmtime.so`.
+- A previous failed compile left stale `.compile.txt`, `.wasm-check.txt`, or partial `.wasm` files under `BIN_DIRECTORY`.
+
+Failed compile output is persisted under the unit's generated path in `BIN_DIRECTORY` and may be reused until the source or compiler inputs change. First fix the source/toolchain issue and reload the page. If the cache itself is suspect, stop UCE, move only the affected unit artifact files or directory aside, and restart so the runtime recompiles from source. Avoid deleting the whole `BIN_DIRECTORY` unless you intentionally want a full rebuild.
+
+### CLI commands fail
+
+Check:
+
+- `CLI_SOCKET_PATH` in `/etc/uce/settings.cfg`
+- `/run/uce/cli.sock` exists
+- `scripts/uce-cli --socket /run/uce/cli.sock /ping` works
+- the target unit defines `CLI(Request& context)`

+# WASI SDK Toolchain Pin
+
+UCE treats WASI SDK as a deployment/runtime dependency, not just a developer build tool.
+
+The runtime compiles `.uce` units to wasm on demand during requests and during the proactive compiler scan. That means every deployment host must have the same compiler/linker toolchain available, and the generated `.wasm`/`.cwasm` artifacts are tied to that toolchain version and UCE unit ABI version.

+1. Update `scripts/install_wasi_sdk.sh` version, URL, and SHA256.
+2. Record the new release and checksum here.
+3. Rebuild `bin/wasm/core.wasm` with `scripts/build_core_wasm.sh`.
+4. Rebuild the native runtime with `scripts/build_linux.sh`.
+5. Clear or invalidate stale unit wasm artifacts by bumping `UCE_UNIT_ABI_VERSION` when required, or by removing affected generated artifacts under `BIN_DIRECTORY`.
+6. Run the full CLI suite including wasm kill tests:
+
+```bash
+scripts/run_cli_tests.sh --include-wasm-kill
+```
+
+## Known footgun
+
+WASI SDK 33's `llvm-nm` was observed to crash on a degenerate but valid unit module with no exported handlers. `scripts/check_unit_wasm.py` treats that specific validator-tool crash as a skipped allocator-definition scan while still rejecting forbidden allocator exports and other ABI violations. This is one reason the toolchain is pinned instead of relying on whatever `/opt/wasi-sdk` happens to contain.

+# UCE WASM Runtime Architecture
+
+Status: current as of the W7e native-pipeline removal (June 2026). This document
+describes the **runtime architecture as built** — the process topology, the
+wasm membrane, the unified request dispatch, and the central WebSocket broker.
+Native `.so` unit execution/dlopen fallback has been removed; the parser and
+preprocessor remain only as the front-end that emits C++ for wasm side-module
+compilation.
+
+The guiding principle: **request code never shares an address space or an
+allocator with the runtime.** Every unit runs as a WebAssembly module inside a
+per-request workspace behind a narrow host membrane. Long-lived connection
+state (WebSocket connections, listening HTTP sockets) lives in dedicated native
+broker processes that own no unit code — they hold the connection and forward
+the actual unit invocation to a clean-engine worker, exactly like a normal
+page render.
+
+---
+
+## 1. Process topology
+
+A single native binary (`uce_fastcgi`) forks into a small set of long-lived
+roles. None of them is special-cased per request mode; the differences are
+purely *which socket a process listens on* and *which function inside a unit
+gets invoked*.

+```
+
+| Process | Owns | Renders units? | Source |
+|---|---|---|---|
+| **Parent** | nothing; supervises children | no | `main()`, `init_base_process()` |
+| **Worker** (×`WORKER_COUNT`) | `FCGI_SOCKET_PATH` (`/run/uce.sock`) + `CLI_SOCKET_PATH` | **yes** — the only processes that run wasm | `listen_for_connections()` |
+| **WS broker** (×1) | `HTTP_PORT` + every live WS connection + `WS_BROKER_SOCKET_PATH` | no — forwards to the pool | `run_ws_broker()` |
+| **serve_http dispatcher** (×bind) | one custom-server bind address | no — forwards to the pool | `custom_server_http_dispatcher_loop()` |
+| **Proactive compiler** | nothing; pre-compiles units | no | `run_proactive_compiler()` |
+
+**only workers instantiate Wasmtime and run unit code.**
+Every connection-owning process (broker, serve_http dispatcher) forwards the
+request invocation back to a worker over `/run/uce.sock` using the minimal
+FastCGI client in [`src/lib/fcgi_forward.h`](../src/lib/fcgi_forward.h). This is
+forced by Wasmtime: an `Engine`/`Store` cannot be safely re-created across
+`fork()`, and the brokers fork from the parent that already touched the
+runtime. So the brokers hold the long-lived connection and units respond to
+events the same way they respond to a page request — through a clean worker.
+
+---
+
+## 2. The membrane and the DValue ABI
+
+Units are compiled to WebAssembly and linked against a host import surface (the
+"membrane"). Host and guest exchange structured values as **UCEB** (a compact
+binary `DValue` encoding — `ucb_encode`/`ucb_decode`); strings cross as
+`std::string` on the native side throughout (no raw `char*` ownership across
+the boundary).
+
+- `DValue` is the universal value type: scalars plus an ordered child map
+  (`_map`, a `std::map<String,DValue>`). `operator[]` is non-const (creates);
+  `.key(k)` is the const probe returning `const DValue*`; `.each(fn)` iterates
+  children yielding `const DValue&`.
+- The request context (`params`/`get`/`post`/`cookies`/`session`, the raw body
+  `in`, and—for WS—the connection context) is marshalled into a single `ctx`
+  DValue, UCEB-encoded, and handed to the workspace. The response (body,
+  headers, status, and any `meta` such as `ws_commands`) comes back the same
+  way.
+
+See [`docs/wasm-phase1-dvalue-abi.md`](wasm-phase1-dvalue-abi.md) for the wire
+format details.
+
+---
+
+## 3. Units, handlers, and export naming
+
+A `.uce` unit compiles to a wasm module that exports one symbol per **handler**.
+There is no per-mode machinery — a "CLI unit", "WebSocket unit", and "page" are
+the same compiled artifact invoked at different exports. The dispatcher passes a
+**handler string**; the host maps it to an export symbol:
+
+```
+__uce_<base>[_<sanitize(suffix)>]
+```
+
+`handler_export_symbol()` (`src/wasm/worker.cpp`) splits on the first `:`:
+
+| Handler string | Export symbol |
+|---|---|
+| `render` | `__uce_render` |
+| `cli` | `__uce_cli` |
+| `websocket` | `__uce_websocket` |
+| `once` | `__uce_once` (optional; absence is not an error) |
+| `serve_http` | `__uce_serve_http` |
+| `serve_http:named` | `__uce_serve_http_named` |
+| `component:CARD` | `__uce_component_CARD` |
+| `exists` | probe only — resolves the unit, loads nothing |
+
+`sanitize_symbol_suffix()` keeps `[A-Za-z0-9_]` (mirrors `ascii_safe_name`).
+`wasm_resolve_target(unit, handler)` (`src/wasm/core.cpp`) resolves the source
+path and looks up the export's funcref slot; `exists` lets callers probe a unit
+without instantiating it.
+
+`wasm_backend_should_handle(request, entry_unit)` checks whether the wasm
+backend is initialized and the requested artifact/handler is currently
+available. If an artifact is cold or stale, dispatch compiles it on demand via
+`get_shared_unit()` and rechecks. There is no native unit-execution fallback.
+
+---
+
+## 4. The workspace runtime
+
+Each request gets a fresh **workspace** — a per-request wasm instance tree with
+the membrane wired in. `wasm_worker_serve(worker, ctx, entry_unit, handler)`
+(`src/wasm/worker.cpp`) is the single entry point for *every* mode:
+
+1. Birth a workspace (CoW-snapshot-based where available).
+2. Resolve `entry_unit` + `handler` to an export; components referenced at
+   runtime are resolved on demand via the `uce_host_component_resolve` hostcall
+   (`component_resolve()` → `__uce_<...>` slot), loading dependency modules
+   lazily and recording resolve counts/timings.
+3. Invoke the export. Unit code calls host functions (filesystem, sqlite, regex,
+   markdown, time, tasks, `ws_*`, …) across the membrane.
+4. Collect the response (`WasmResponse`: body, headers, status, `meta`).
+
+Because the workspace owns no process-lifetime state, a unit crash or trap is
+contained: it fails the one request and the worker stays healthy. Workers
+suspend the native SIGSEGV/SIGILL recovery handler around the wasm call so that
+Wasmtime's own trap signals are not escalated into a native fatal signal (see
+`serve_via_wasm` in `handle_complete`).
+
+---
+
+## 5. Request dispatch (`handle_complete`)
+
+`handle_complete()` (`src/linux_fastcgi.cpp`) is the worker's single dispatch
+point. It selects a handler string from request params and calls the same
+`serve_via_wasm(entry_unit, handler)` lambda for all of them:
+
+```
+UCE_WS == "1"            → serve_via_wasm(entry_unit, "websocket")
+request.resources.is_cli → serve_via_wasm(entry_unit, "cli")
+UCE_SERVE_HTTP == "1"    → serve_via_wasm(entry_unit, "serve_http"[:fn])
+otherwise (page)         → serve_via_wasm(entry_unit, "render")
+```
+
+The `UCE_*` params are set by whichever broker forwarded the request:
+
+- **Page render**: FastCGI nginx → `/run/uce.sock` directly; no `UCE_*` flags → `render`.
+- **CLI**: the CLI socket sets `is_cli`.
+- **serve_http**: the custom-server dispatcher sets `UCE_SERVE_HTTP=1` plus
+  `UCE_SERVE_HTTP_FUNCTION` and rewrites `SCRIPT_FILENAME` to the configured
+  unit (`custom_server_http_complete`).
+- **WebSocket**: the WS broker sets `UCE_WS=1` and carries the connection
+  identity as `UCE_WS_*` params (see §6). `handle_complete` rebuilds
+  `request.resources.websocket_*` and `request.connection` from them before
+  invoking `__uce_websocket`.
+
+If a unit still cannot be served after the on-demand wasm compile, the worker
+returns a clean 500 with the wasm/compile error; it does not execute native unit
+code.
+
+---
+
+## 6. The central WebSocket broker
+
+**One process owns the HTTP port
+and every WebSocket connection**, so any unit's `ws_*` call can reach any or all
+connections, and a unit-code crash (which happens in a worker) never drops live
+connections.
+
+### 6.1 Inbound: a WS frame → a worker render (non-blocking)
+
+`ws_broker_ws_message(request, message, opcode)` fires when a complete
+(reassembled) WS message arrives on a connection. It does **not** block the
+broker loop:
+
+1. Build FastCGI params: `SCRIPT_FILENAME`, `REQUEST_METHOD=GET`, a
+   `REQUEST_URI` (required — `handle_request()` rejects requests without one
+   *before* `on_complete` runs), `UCE_WS=1`, and the connection context as
+   `UCE_WS_CONNECTION_ID / SCOPE / OPCODE / BINARY / CONNECTIONS / STATE`.
+2. The message rides as `UCE_WS_MESSAGE` (base64) with an **empty STDIN body** —
+   a non-empty STDIN makes the FastCGI transport flush a premature response
+   before `on_complete` ever runs.
+3. Connect to `/run/uce.sock` (non-blocking) and queue the encoded request in
+   `ws_broker_outbound[fd]`.
+
+`ws_broker_drain_outbound()` runs after every `process(50)` tick: it finishes
+writing each queued request, then drains and discards the reply (the unit's
+output comes back via the command socket, not this reply), closing the fd when
+the worker closes its end.
+
+### 6.2 Outbound: `ws_*` commands flushed back to the broker
+
+Any unit code — not just WebSocket handlers — may call `ws_send` / `ws_send_to`
+/ `ws_close`. In the workspace these **record dispatch commands** rather than
+touching a socket (the workspace owns no connections); `wasm-core`'s `ws_*`
+(`src/lib/sys.cpp`) append to `websocket_dispatch_commands`, and
+`finish_response_meta` (`src/wasm/core.cpp`) emits them as `ws_commands` (plus
+`ws_connection_state` if the handler mutated per-connection state).
+
+`wasm_backend_serve` (`src/wasm/backend.cpp`) flushes that batch at workspace
+teardown — in **any** scenario, not just WS handlers — to the broker's command
+socket (`WS_BROKER_SOCKET_PATH`, `/run/uce/ws-broker.sock`) via
+`fcgi_forward_request` with `UCE_WS_DISPATCH=1`. This is the only path WS data
+takes out of a workspace.
+
+`ws_broker_apply_commands()` decodes the batch and applies each command against
+the full registry it owns: `broadcast` (by scope), `send_to` (by connection id),
+`close`. If the batch carries `connection_state`, it persists that onto the
+matching live connection's `websocket_state`.
+
+### 6.3 Un-upgraded HTTP on the WS port
+
+The WS port can also receive ordinary (non-Upgrade) HTTP requests.
+`ws_broker_complete()` routes by param: `UCE_WS_DISPATCH=1` → apply commands;
+otherwise → `forward_request_to_worker()` — the *same* shared facility the
+serve_http dispatcher uses, so there is no duplicated request-forwarding code.
+
+### 6.4 The broker loop
+
+`run_ws_broker()` drops the worker listeners it inherited
+(`close_inherited_server_sockets`), installs permissive `on_request`/`on_data`
+handlers (it renders nothing, so it accepts every request straight through to
+`on_complete`), wires `on_complete=ws_broker_complete` and
+`on_websocket_message=ws_broker_ws_message`, listens on `HTTP_PORT` and the
+command socket, and loops `process(50)` + `drain_outbound()`. The design is
+**non-blocking outbound dispatch + async command-socket flush, all in the
+broker's single epoll loop** — the broker never blocks on a worker.
+
+The parent respawns the broker if it dies (`ws_broker_alive` / `ensure_ws_broker`
+in `main()`). 
+
+---
+
+## 7. The serve_http facility
+
+`serve_http` units are reachable on their own bind address via a custom-server
+dispatcher (`custom_server_http_dispatcher_loop`). The dispatcher owns the bind
+socket and, on each request, sets `UCE_SERVE_HTTP=1` + the configured unit/
+function and calls `forward_request_to_worker()`. The worker then runs
+`serve_via_wasm(entry_unit, "serve_http"[:fn])`. This is the same
+hold-connection-forward-render model as the WS broker, sharing
+`forward_request_to_worker` and `fcgi_forward.h`.
+
+---
+
+## 8. Build / object layout
+
+The native side is split into separately-compiled objects so editing the wasm
+runtime does not recompile the whole TU (`scripts/build_linux.sh`):
+
+| Object | Contents |
+|---|---|
+| `bin/sqlite3.o` | sqlite amalgamation (cached) |
+| `bin/wasm.o` | `src/wasm/wasm_module.cpp` (backend.cpp + worker.cpp + wasmtime) |
+| `bin/main.o` | `src/linux_fastcgi.cpp` (includes `lib/uce_lib.cpp`) |
+
+Linked into one `-rdynamic` binary. ODR hazards across the objects are handled
+deliberately: `context` and `my_pid`/`parent_pid` are `extern` (guarded for the
+wasm core vs. unit builds), `operator new`/`delete` live in `types.cpp`, and
+header free-functions are `inline`. The wasm backend exposes only declarations
+(`src/wasm/backend.h`) to `main.o`.
+
+---
+
+## 9. Configuration keys
+
+| Key | Default | Meaning |
+|---|---|---|
+| `WASM_BACKEND_VERBOSE` | `0` | Emit `X-UCE-Wasm-*` workspace timing headers (benchmark only). |
+| `FCGI_SOCKET_PATH` | `/run/uce.sock` | Worker pool FastCGI socket (brokers forward here). |
+| `CLI_SOCKET_PATH` | `/run/uce/cli.sock` | Worker CLI socket. |
+| `HTTP_PORT` | `8080` | Raw HTTP + WebSocket port — owned by the WS broker. |
+| `WS_BROKER_SOCKET_PATH` | `/run/uce/ws-broker.sock` | Broker command socket for `ws_*` flushes. |
+| `WORKER_COUNT` | `4` | Number of uniform worker processes. |
+
+---
+
+## 10. Testing
+
+- **Regression gate**: `scripts/run_cli_tests.sh --include-wasm-kill` runs the
+  in-runtime CLI suite (`site/tests/cli_runner.uce`) plus the site test pages.
+
+- **WebSocket end-to-end**: a headless client performs a raw WS handshake to
+  `:HTTP_PORT` with path `/site/tests/websockets.ws.uce` (self-resolving
+  `SCRIPT_FILENAME`) and asserts the `hello-ack` frame — exercising the full
+  broker → worker → broker → client chain across process boundaries.

rootandClaude Opus 4.8	4f84ac544d	feat: request_perf() worker-side timing hostcall; restore demo System Info Units run in the wasm sandbox, so my_pid/parent_pid/context.server->request_count read as sandbox stubs — the demo System Info counters were broken, and there was no authoritative server-side request timing available to unit code (client-side measurement cannot see queue/dispatch latency). Add a request_perf() unit API backed by a new uce_host_request_perf hostcall. The native worker answers it live, returning a DValue: worker_pid, parent_pid, request_count, accept_us = (time_start - time_init)1e6 (entry -> dispatch wait), running_us = (now - time_start)1e6 (since dispatch, live), total_us = (now - time_init)*1e6 (since the request entered UCE), workspace_birth_us. time_init is captured at request entry (handle_request, with a handle_complete fallback); a RequestPerfSnapshot {pids, request_count, time_init, time_start} is threaded from wasm_backend_serve through wasm_worker_serve onto the workspace, and the hostcall computes the live deltas at call time. Wired like uce_host_units (sized DValue hostcall): core_hostcalls.syms + sys.cpp/sys.h request_perf(). site/demo/index.uce System Info now uses request_perf() and shows the real worker PID, an incrementing per-worker request count, and the timing counters. Implemented via the pi agent (gpt-5.3-codex-spark); a review of the live numbers caught accept_us mistakenly computed as (now - time_init) (== total_us), fixed to the dispatch wait (time_start - time_init). Independently verified on the host: System Info shows non-zero PIDs, incrementing count, accept_us ~50us << total_us ~2.4ms with accept+running==total; run_cli_tests --include-wasm-kill => 87 passed, 0 failed, 0 skipped.

rootandClaude Opus 4.8	83ab9e10f7	perf: extend the compiled-module disk cache to per-unit modules Follow-up to `560290c`. Per-unit .wasm modules were still Cranelift-compiled per worker on first use (~40-70ms each), so with 8-call worker recycling fresh workers re-JIT every unit they touch. Refactor the core cache logic into a shared WasmWorker helper: - cached_wasm_path(p): maps <...>.wasm -> <...>.cwasm. - load_or_compile_cached_module(engine, cached, wasm, bytes, err): deserialize_file the .cwasm when it is newer than the .wasm; otherwise Module::compile + serialize, written atomically (temp+rename); deserialize failure falls back to compile. Both the core module load and unit_module() now go through this helper, so unit artifacts get the same <unit>.uce.cwasm cache the core got. Independently verified on the host: fresh-worker first-hit unit latency ~40-70ms -> ~3-21ms; full suite wall-clock 20.5s -> 6.5s (and ~40s before any caching); run_cli_tests --include-wasm-kill => 87 passed, 0 failed, 0 skipped. Implemented via the pi agent (gpt-5.3-codex-spark sub-model). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-15 00:16:41 +00:00
rootandClaude Opus 4.8	560290ca1d	perf: cache the compiled core module so fresh workers deserialize, not recompile Workers recycle every 8 requests (calls_until_termination=8). Each fresh worker ran wasmtime::Module::compile() on the 6.8MB bin/wasm/core.wasm — a ~1.3s Cranelift JIT — on its first request, so every ~8th request spiked to ~1.3s and dominated suite wall-clock. Cache the compiled artifact: on worker core-module load, if bin/wasm/core.cwasm exists and is newer than core.wasm, load it via Module::deserialize_file() (mmap, ~ms); otherwise Module::compile() as before and atomically (temp+rename) write the serialized artifact for the next worker. Deserialize failure / stale cache falls back to a normal compile, so it is self-healing; rebuilding core.wasm (newer mtime) invalidates the cache. Engine config (epoch_interruption, signals_based_traps(false)) is unchanged, which the serialized format requires. Implemented via the pi agent (delegated to a gpt-5.3-codex-spark sub-model). Independently verified on the host: worker-startup request latency drops from ~1.3s to ~23ms (warm 12x /demo/hello.uce: all <=0.023s, no spikes); full suite wall-clock ~40s -> 20.5s; run_cli_tests --include-wasm-kill => 87 passed, 0 failed, 0 skipped.

rootandClaude Opus 4.8	bfd6d33829	W7f: sweep dead/legacy/fallback leftovers after native-pipeline removal Post-deletion cleanup (units run only on wasm): - types.h/compiler.cpp: drop the native-era SharedUnit fields so_name, bin_file_name, and the opt_so_optional cache-mode plumbing (no native optional .so path remains). The per-unit compile lock is re-keyed from so_name+.lock to wasm_name+.lock (still per-unit). - unit_info() and to_string(SharedUnit) no longer expose .so artifact fields. - backend.h: drop the stale "+ fallback-token gate" comment. - Docs/comments corrected to wasm-only reality: README, tests/README, site/doc C++ preprocessor + error_pages + unit_info pages, site/info intro, site/demo/unit-browser artifact card; the Phase-5 native-vs-wasm benchmark harness (tests/wasm_benchmark.py) reframed for the wasm-only backend. Audit confirmed no live references remain to so_handle, load_shared_unit, compiler_load_shared_unit, compiler_invoke/_cli/_websocket/_serve_http, COMPILE_SCRIPT/COMPILE_WASM_UNITS, or the native export-symbol constants; request_ref_handler/dv_call_handler are kept (live wasm funcref casts). Swept via the pi agent (delegated to a gpt-5.3-codex-spark sub-model); independently re-verified on the host: run_cli_tests --include-wasm-kill => 87 passed, 0 failed, 0 skipped.

rootandClaude Opus 4.8	cf51336873	W7e: delete the native unit pipeline (.so compile + dlopen execution) Units now run exclusively on wasm; the native generated-C++ -> clang -> .so -> dlopen path and its request-time fallback are removed. - Dispatch (linux_fastcgi.cpp): the 4 handle_complete branches + the CLI-socket path route every request through wasm (wasm_ready compiles cold/stale on demand); a wasm-unavailable unit now yields a clean error page (fail_wasm_unavailable / render_request_failure) instead of native execution. compiler_invoke / _cli / _websocket / _serve_http deleted. - compiler.cpp (-1274): removed the native .so compile (COMPILE_SCRIPT), load_shared_unit, dlopen/dlsym/dlclose, compiler_load_shared_unit, and the SharedUnit .so function-pointer fields (on_setup/on_render/on_component/ on_websocket/on_cli/on_once/on_init) in types.h/types.cpp. compile_shared_unit now builds only the .wasm side-module; the .uce preprocessor/parser front-end is kept (it emits the C++ the wasm compile consumes). - unit_call()/component()/once/init now resolve across units through the wasm host component resolver (uce_host_component_resolve) instead of native dlsym; configured runtime error pages render through the wasm backend. - Dropped the WASM_BACKEND_ENABLED feature flag and dead COMPILE_SCRIPT / COMPILE_WASM_UNITS config; unit ABI freshness tied to UCE_UNIT_ABI_VERSION; guard against serving a stale .wasm for a deleted source; retired the obsolete W5 native-vs-wasm toggle script. Docs updated. Implemented via the pi agent (with 3 delegated sub-reviews); independently re-verified on the build host: run_cli_tests --include-wasm-kill => 87 passed, 0 failed, 0 skipped.

rootandClaude Opus 4.8	fb728d63bc	W7e stage B: factor the .wasm artifact into unit compile-freshness inspect_shared_unit_filesystem() tracked only the .so mtime, so a missing or stale .wasm with a current .so never triggered a rebuild and the unit fell to native indefinitely (the in-process cache also never invalidated). Account for su->wasm_name when wasm unit compilation is enabled: a unit counts as compiled only as of the OLDER of the two artifacts; a missing .wasm forces a recompile. Closes the cached-vanished-.wasm gap noted in the stage A review. Verified independently on the build host: run_cli_tests --include-wasm-kill => 87 passed, 0 failed; delete-.wasm-then-request rebuilds the artifact.

rootandClaude Opus 4.8	2debd33804	W7e: wasm-preferred dispatch + compile-on-demand; harden unit ABI validator - Dispatch (linux_fastcgi.cpp): route every request through wasm. On a cold/stale artifact, compile the unit on demand (get_shared_unit, forced) and serve wasm; native compiler_invoke* remains only as a fallback when wasm cannot be made ready (compile failure / backend disabled). Applies to the 4 handle_complete branches and the CLI socket path. - backend.cpp: delete the now-vestigial native-only fallback token gate (wasm_backend_native_fallback_), empty since W7d; should_handle now gates on config + current artifact + healthy worker only. - check_unit_wasm.py: skip the defense-in-depth llvm-nm allocator scan when llvm-nm SIGSEGVs on a degenerate-but-valid module (e.g. a unit with no exported handlers). Fixes site/demo/empty.uce, the last unit that could not produce a .wasm; forbidden allocator exports* are still rejected. A pi-assisted review caught that the compile-freshness check keys off the .so mtime only, so force_recompile is required to rebuild a missing/stale .wasm; a unit already cached in-process whose .wasm later vanished still uses native fallback (closed in W7e stage B). Native execution is otherwise bypassed for all real traffic. Verified: scripts/run_cli_tests.sh --include-wasm-kill -> 87 passed, 0 failed.

rootandClaude Opus 4.8	8587fbc5aa	wasm runtime: central WS broker, unified handlers, W7d holdouts, membrane completeness - WS: a dedicated broker process owns HTTP_PORT + every connection; it forwards renders to the worker pool over uce.sock (non-blocking) and applies ws_* command batches flushed back at workspace teardown. Removes the now-dead per-worker websocket executor (-509 lines). - Dispatch: unify CLI / WebSocket / serve_http / page render through one serve_via_wasm(entry_unit, handler) path; handler string -> __uce_<handler> export symbol. - W7d: rewrite zip.uce to the membrane return-value error contract (no C++ try/catch), error-reporting.uce to genuine wasm traps instead of throw, and sharedunit.uce to unit_info(); empty the native-only token gate. - Membrane: wire ls / mkdir / file_mtime through new uce_host_file_list / uce_host_file_mkdir / uce_host_file_mtime hostcalls (resolve_guest_file gains directory support). Fixes /doc/index.uce listing nothing; adds a regression assertion that the index enumerates items. - Docs: add docs/wasm-runtime-architecture.md; record the W7e staged native- deletion plan in WASM-PROPOSAL.md. Verified: scripts/run_cli_tests.sh --include-wasm-kill -> 87 passed, 0 failed. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-14 17:51:51 +00:00
