- 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.
