- 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>
