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.

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.

- 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.

- 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.
