Summary:
- Keep Channels responsive by opening on cached/runtime snapshots, bounding live probes, and preventing stale slow probe results from replacing newer snapshots.
- Reduce Control UI churn by scoping Nodes polling to the active Nodes tab, debouncing sessions.changed reconciliation, and bounding secondary chat/session refreshes.
- Scope config schema analysis before section-limited renders so excluded root sections are not fully analyzed.
Verification:
- pnpm test ui/src/ui/app-channels.test.ts ui/src/ui/controllers/channels.test.ts ui/src/ui/app-settings.refresh-active-tab.node.test.ts ui/src/ui/app-gateway.sessions.node.test.ts ui/src/ui/app-lifecycle-connect.node.test.ts ui/src/ui/controllers/sessions.test.ts ui/src/ui/views/config.browser.test.ts src/gateway/server-methods/channels.status.test.ts src/gateway/control-ui.http.test.ts ui/src/ui/app-polling.node.test.ts ui/src/ui/app-gateway-chat-load.node.test.ts ui/src/ui/app-gateway.node.test.ts ui/src/ui/app-chat.test.ts ui/src/ui/app-render.helpers.node.test.ts ui/src/ui/app-lifecycle.node.test.ts
- pnpm exec oxfmt --check --threads=1 <changed files>
- git diff --check origin/main...HEAD
- node scripts/run-oxlint.mjs --tsconfig config/tsconfig/oxlint.core.json <changed TypeScript files>
- pnpm changed:lanes --json
Note: local pnpm check:changed reached core lint and failed on src/gateway/server-methods/nodes.invoke-wake.test.ts, which is unchanged in this PR and already present on current origin/main; changed-file lint passed under the same repo wrapper.
Provider applyConfig patches merged during models auth login could replace
agents.defaults.model.primary even without --set-default. Snapshot the prior
defaults.model and restore it after the patch unless the user opts in.
Fixes#78162.
