The 1.62.3 release publishes the CopilotThreadsDrawer redesign (web-components +
react-core wrapper) and the stateless /suggest feature. Bump the 15 integration
examples that consume the drawer from 1.62.2 -> 1.62.3 (package.json + lockfiles)
so they pick up the released packages alongside this branch's example CSS.
Validated: langgraph-js runs on the published 1.62.3 (no local links) — the
redesigned drawer renders (New Conversation, Recent Conversations, filter funnel,
desktop collapse toggle, per-row kebab), threads are licensed, and a real agent
message round-trips.
The langgraph/strands examples pinned @copilotkit/runtime via a
self-referential npm alias (npm:@copilotkit/runtime@x) left over from the
de-fork branch (2155821b8), where it forced registry resolution while
react-core used workspace:*. That alias is functionally identical to a
raw pin and react-core was already reverted, so drop the alias in the four
remaining files (langgraph-fastapi, langgraph-js, langgraph-python,
strands-python) and regenerate their lockfiles.
Bump the 16 integration examples already on the 1.62.x line from 1.62.1
to 1.62.2 (the just-published release), including their in-tree agent
sub-packages (langgraph-js/agent sdk-js, agentcore CDK lambda runtime)
that had drifted to 1.61.0. Regenerated the co-located package-lock.json
files against the published 1.62.2.
a2a-a2ui and agent-spec remain at 1.61.0 (QA-held; out of scope).
1.61.0 is now published. Regenerates all 20 starter package-lock.json files
so @copilotkit/* resolves to 1.61.0 and the transitive
@copilotkit/license-verifier moves 0.4.2 -> 0.5.0 (shipped by runtime@1.61.0).

The chat never responds and the browser console shows
"TypeError: Failed to execute 'fetch' on 'Window': Illegal invocation"
on every agent run (onRunFailed, agentId: default).
Root cause is in @ag-ui/client@0.0.56's HttpAgent: it stores the global
fetch unbound (`this.fetch = config.fetch ?? fetch`) and later invokes it
as `this.fetch(...)`, so native fetch runs with the agent instance as its
receiver instead of `window`. Native fetch is brand-checked and throws
"Illegal invocation". It surfaces in both dev and prod.
Fixed upstream in @ag-ui/client@0.0.57 (`config.fetch ?? ((url, init) =>
fetch(url, init))`), which shipped in @copilotkit/* 1.60.1. Bumping these
examples 1.60.0 -> 1.60.1 pulls 0.0.57 transitively; lockfiles regenerated.
Scope: only the examples that take @ag-ui transitively from react-core are
bumped here. Other integration examples force-pin @ag-ui via `overrides`
to 0.0.53/0.0.55, where 1.60.1 would create a version skew; those need a
per-integration bump and are intentionally left out of this change.
Bumps every @copilotkit/* pin (react-core, react-ui, runtime, a2ui-renderer,
sdk-js) from 1.59.5 to 1.60.0 across the threads-enabled integration examples,
and regenerates each package-lock.json to the 1.60.0 dependency closure.
Excludes the vestigial langgraph-python-threads example.
- Skip copilotkit.connectAgent when CopilotChat lacks a caller-supplied
threadId — a locally-minted UUID has no backend record, so /connect
would always 404 on the intelligence platform.
- Suppress the welcome screen while a connect is in flight and
unconditionally when the caller has supplied a threadId
(hasExplicitThreadId). Prevents the "How can I help you today?"
flash on thread switch.
- Gate suggestions on !isConnecting && !isRunning to avoid painting
them against a mid-replay message tree.
- Defer the isConnecting release by one animation frame so trailing
bootstrap renders commit before the flag flips.
- Reserve room for the "Powered by CopilotKit" license badge via a
new --copilotkit-license-banner-offset CSS var published by the
banner on mount; chat input consumes it only when bottom-anchored.
- Sort and display threads by lastRunAt (fallback to updatedAt →
createdAt) so metadata-only actions like archive/rename don't
reshuffle the list.
- useThreads waits for runtimeConnectionStatus === Connected before
dispatching the store context, eliminating the speculative /threads
fetch that fired before /info returned wsUrl.
Threads example polish: restore button + tooltips on
archive/restore/delete, segmented Active/All filter, graceful error
state, skeleton rows on initial load, stable scrollbar gutter,
pre-paint dark-mode class, logo position stable across app/chat
modes, drop dynamic-import drawer wrapper that caused null first
paint, archived-row dimming via child colors instead of opacity.
Tests:
- CopilotChat.absentThreadConnect: connect is skipped without a
threadId, fires when supplied via prop or config.
- CopilotChatView.connectingGate: isConnecting suppresses welcome;
hasExplicitThreadId suppresses welcome on empty chat.
- threads (core): lastRunAt sort fallback ordering.
- use-threads: Connecting-state gate defers /threads until Connected.
