The integration-demo parity-check CI job was red on main: langgraph-js,
strands-python, and langgraph-fastapi diverged from the langgraph-python
north-star on two tracked verbatim files.
Root cause is the partial revert in 3721e7b36 (Revert of #5151), NOT #5222.
The v2 API migration (23af69041) moved north-star and all instances to the
v2 surface. The revert rolled the *instances'* example-layout/index.tsx and
docker-route-override.ts back to the v1 API (@copilotkit/react-core,
@copilotkit/runtime) while leaving the north-star on v2
(@copilotkit/react-core/v2, @copilotkit/runtime/v2). That left the demos
internally inconsistent: each instance's real src/app/api/copilotkit route
already uses runtime/v2 on copilotkit 1.59.3, but its Docker route override
and example layout were stuck on v1.
Re-baseline forward by syncing the three instances to the v2 north-star via
`pnpm parity:sync --all`. Only the 5 drifting verbatim files change; no
package.json keys move (all instances already pin 1.59.3) and no
agent-surface or allowed-divergence files are touched. `pnpm parity:check`
is now green (0 errors across all instances).
Addresses the blocking review on #5151:
1. Starter smoke 'Popup Assistant' timeouts (adk, agno, mastra,
ms-agent-framework-python/dotnet): the pages passed the dead v1 label keys
(labels.title / labels.initial), which v2 CopilotSidebar ignores — the
header rendered the default 'CopilotKit Chat' so the smoke's
text=Popup Assistant wait timed out. Map to the v2 CopilotChatLabels keys:
title -> modalHeaderTitle, initial -> welcomeMessageText. Verified live:
SSR now renders 'Popup Assistant'.
2. llamaindex TypeError (reading 'proverbs'): the page still used the v1
useAgent API ({ state, setState } = useAgent({ name, initialState })) —
v2 returns { agent }, so state was undefined at render. Migrate to the v2
pattern (agent.state with a guarded default + agent.setState + one-time
seed effect), and fix its dead v1 label keys too. Verified: next build
prerenders all pages cleanly.
3. parity-check drift: ran _parity/sync.ts --all — syncs example-layout
(mobile-header fix), layout.tsx, docker-route-override.ts to the
north-star, and bumps @copilotkit/* to 1.59.1 in langgraph-fastapi and
strands-python. parity verify: 0 errors across all instances.
(next-env.d.ts is gitignored repo-wide; verify warns-and-skips it in a
clean checkout, so it is intentionally not committed.)
4. Trailing-whitespace diff-check failure (showcase google-adk agent): already
resolved by the merge of main (the file matches main; diff --check clean).

Root cause of the parity-check CI failures:
The 5 verbatim-tracked files in `examples/integrations/langgraph-python/`
(the north-star) all carried `typescript/consistent-type-imports` and
`react/self-closing-comp` warnings that oxlint wants to auto-fix.
The lefthook pre-commit `lint-fix` hook is scoped to staged files
and re-stages fixes via `stage_fixed: true`. So when I ran
`pnpm parity:sync --target=strands-python` and staged the synced
files, oxlint --fix rewrote them on commit to satisfy the
type-imports rule — turning `import { NextRequest }` into
`import type { NextRequest }`, etc. The north-star was never touched
by the hook (nothing staged in langgraph-python/), so it kept the
un-fixed form. The two diverged at commit time and parity:check
caught the drift.
Two prior commits (0559faf3d, 80425fcc8) tried to land the sync but
each landed empty: lefthook + stage_fixed reverted the working-tree
changes to match the north-star's un-fixed form, then the linter's
auto-fix re-applied the same delta the hook had just undone — net
zero file content but with the linter-fixed form, which the post-
commit hook then reverted again. Hard to debug because `git
commit` reported success and shortstat hid the no-op.
This commit fixes the root cause instead of the symptom:
1. Apply `pnpm exec oxlint --fix` directly to the 5 north-star
files (`docker-route-override.ts`,
`src/app/declarative-generative-ui/renderers.tsx`,
`src/components/ui/{badge,button}.tsx`, `src/lib/utils.ts`).
The fixes match what the pre-commit hook would have applied:
type-only imports → `import type`, self-closing JSX → `<X />`.
2. Re-run `pnpm parity:sync` for all three instances
(strands-python, langgraph-fastapi, langgraph-js) so they
verbatim-match the new north-star.
3. Verified `pnpm parity:check` exits 0; all four trees lint clean
(`pnpm exec oxlint examples/integrations/.../`).
Net effect: every instance now matches the north-star byte-for-byte,
and the lint-fix hook is a no-op on these files going forward.
Files touched per directory (5 each, except strands-python which had
docker-route-override.ts already synced in a prior attempt):
examples/integrations/langgraph-python/ — 5 files
examples/integrations/langgraph-fastapi/ — 5 files
examples/integrations/langgraph-js/ — 5 files
examples/integrations/strands-python/ — 4 files

Align langgraph-js with examples/integrations/langgraph-python via the
parity tooling. Remove legacy app/ layout, adopt src/ layout, rewrite
the TS agent to expose the tracked tool surface (manage_todos,
get_todos, query_data, generate_a2ui, search_flights) and todos state,
and write the canonical PROMPT.md. Keeps LangGraphAgent + stategraph
runtime (allowed divergence per the manifest); brings deps,
Dockerfile.app, entrypoint, showcase metadata, and shared UI into
lockstep. Parity verifier: 88 ok / 0 error.
