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.

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.

- 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.
