- resolve.ts: gate the display branch on linux (the native backend drives exactly darwin/win32/linux) and require a zenity/kdialog binary on PATH, probed once at boot (new probe.ts, injected predicate for tests); type bindHost as the webserver schema's closed union. - index.ts: the disposer now joins the removed entry's fiber teardown so unloading the chooser settles only after the backend quiesced; export BACKEND_PACKAGES as the runtime-string source of truth. - verify-cordis-config: a composition mounting -auto must declare both backends as dependencies (negative-tested), since keyless Linux CI only ever resolves browse and would hide a dropped -native dep. - apps/web scaffold: pin -browse via disable+insert (goldens are interaction-specific); fix the stale workspace-flow comment. - docs/module-graph.md regenerated; README + Agent Note document the ssh -L shape, the PATH-only probe, and the new gate (zh pairs re-paired). - composition spec: assert teardown quiescence without a loader await, cover external entry removal, and await the loader's self-dispose disabled-persist so it cannot race temp-dir teardown.
