TanStack's chat() engine runs a multi-turn agent loop: after the model
returns tool calls, it tries to execute them via processToolCalls().
Frontend-only tools (like render_pie_chart) are unknown to TanStack, so
executeToolCalls() treats them as errors and buildToolResultChunks()
re-emits TOOL_CALL_END without a preceding TOOL_CALL_START. The ag-ui
verify middleware rejects this duplicate.
Fix: track a runFinished flag in convertTanStackStream and discard all
events after the first RUN_FINISHED, which marks the boundary between
the streaming pass and TanStack's internal tool execution loop.
Also adds built-in-agent to docker-compose.local.yml and local-ports.json.
Picks up ag-ui-protocol/ag-ui#1578 — `import * as jsonpatch from
"fast-json-patch"` produced an empty namespace under Node native ESM
because fast-json-patch@3.x populates exports via Object.assign, which
the CJS→ESM named-export detector cannot see. Result: every STATE_DELTA
and ACTIVITY_DELTA event threw "applyPatch is not a function", and
LangGraph generative UI streams floods the console with the failure on
each patch.
0.0.53 switches to a default import so the emitted bundle works under
both ESM and CJS consumers. Bumped @ag-ui/core and @ag-ui/encoder in
lockstep since they share the release.
The prepack script ran `pnpm run build` during `pnpm publish`, duplicating
the build that prerelease.ts/publish-release.ts already do across the
workspace. With tsdown's `exports: true` regenerating package.json's
exports field on every build, the second rewrite happened mid-publish
and pnpm's pack step failed with ENOENT on the staging tarball.
No other monorepo package has prepack — bringing a2ui-renderer in line.

Iterate on the image attachment rendering based on review feedback:
- Reduce thumbnail size to 80x80 (down from 300x300) so attachments
read as compact thumbnails like Claude's chat UI
- Render attachments above the message text instead of below, and lay
multiple attachments out in a horizontal row (flex-row + flex-wrap +
justify-end) instead of stacking vertically
- Add a muted background so transparent images stay readable
- Extract Lightbox + useLightbox into a shared module so the rendered
attachment can reuse the same click-to-zoom modal as the queue preview;
clicking a thumbnail now opens it in a fullscreen lightbox with a
view-transition morph

Constrain image attachments to a 300x300 max size with object-cover and
12px rounded corners so they appear as small thumbnails in chat instead
of filling the message width. Applies to both the v2 renderer (Tailwind)
and the legacy react-ui renderer (CSS).

## Summary
- Explicitly defaults `streamSubgraphs: true` in `LangGraphAgent.run()`
forwardedProps so subagent streaming works with `@ag-ui/langgraph`
0.0.31+, which changed the default from `true` to `undefined`
- Uses nullish coalescing (`??`) so explicit user overrides (including
`false`) are preserved
- Fixes 6 showcase integrations failing E2E probes on the `subagents`
feature
## Why
`@ag-ui/langgraph` 0.0.31 removed the `?? true` fallback on
`streamSubgraphs` in `handleStreamEvents()`. The CopilotKit runtime
never explicitly set this prop, so subgraph event forwarding became
silently disabled. This caused all subagent-dependent demos to stop
working.
A previous v1 fix (commit `21e12afca`) handled this in the now-deleted
`agui-action.ts`, but the logic was lost during the v2 migration.
## Additional context
Investigation identified a second issue: `@ag-ui/langgraph` 0.0.34
includes state snapshot fixes needed for shared-state-read/write
features, but 0.0.34 is not yet published on npm (0.0.31 is latest). The
ag-ui team needs to cut a release. Full analysis: [Notion
write-up](https://app.notion.com/p/3513aa381852812a9ecef5fbf1e71739)
## Test plan
- [x] Runtime tests pass (1412/1412)
- [x] 7-agent CR converged Round 1 (0 findings)
- [ ] Verify showcase E2E probes for subagent features turn green after
merge
Express 4 does not support the {*splat} wildcard syntax introduced in
Express 5. Replace string-based wildcard patterns with RegExp routes
that work across both major versions.
The @ag-ui/langgraph 0.0.31+ changed the default for streamSubgraphs
from true to undefined, breaking subagent streaming. This enriches the
run() input's forwardedProps with streamSubgraphs: true as a default,
while preserving any explicit user override via the nullish coalescing
operator.
Adds a `zodState` helper that attaches a `~standard.jsonSchema.input`
hook to Standard-Schema-compatible schemas (e.g. Zod). Without this,
Zod v4 fields carry `~standard.validate` + `vendor` only, so
LangGraph's `isStandardJSONSchema()` returns false and
`getJsonSchemaFromSchema` (called from `StateSchema.getJsonSchema`)
silently drops them from the graph's `output_schema`. AG-UI
`STATE_SNAPSHOT` events then filter the field out of the payload sent
to the frontend, even though the underlying thread state has it.
Wraps the internal `copilotkit` field in `copilotKitStateSchema` with
`zodState(...)` and exports the helper for user state schemas.
Bumps `@ag-ui/langgraph` to 0.0.30 and `@langchain/{core,langgraph}` /
`langchain` to the v1.1.41 / v1.2.9 / v1.3.4 line, which is the source
of the Zod v4 behavior this fix targets.
Recreates the sdk-js portion of #4320.

Needed for turnIndex/sequenceIndex fixture matching in D5 multi-turn
conversations. Updated in both packages/runtime (devDep) and
showcase/scripts (dep).
Express 4.20+ uses path-to-regexp v8 which requires named wildcard
params. Bare * is no longer valid — use {*splat} syntax instead.
Updated production code (express.ts) and test (express-fetch-bridge).
Restores express >=4.20.0 override now that code is compatible.
Phase 2: upgrade existing overrides to higher patched versions
Phase 3: add 36 new safe overrides for all resolvable transitive deps
Phase 4: bump storybook devDeps, vite in react-router, vitest in demo-agents, next canary
Remaining 3 are truly unfixable:
- parse-git-config: no patch exists (danger devDep)
- elliptic: no patch exists (storybook crypto chain)
- next: example on 15.x canary, advisory needs 16.x

The extension is a leaf node in the monorepo dependency graph (nothing
depends on it) and has its own independent release cycle. The standalone
repo at CopilotKit/vscode-extension has full git history, working CI,
verified OIDC publishing, and branch protection.
Replaces the locked-card UI inside the threads gate with the new
private-beta modal: kicker pill, gradient "Threads" title with body
copy, three checkmark bullets, dark MonoPillButton CTA that opens the
HubSpot waitlist form in a new tab, and a dashed divider over the
invite-code row.
Adds an "unlocking" confirmation card (gradient circle, "Welcome to
Threads", "Loading your conversations…") shown for ~2s after a valid
code before the real Threads UI is revealed.
Invalid-code state now flashes a red input border + "That code isn't
valid. Double-check your invite email." copy that auto-clears after
1600ms, matching the design.
Backdrop (gradient + blurred ellipses) is intentionally preserved.

Drawer-toggle button used to get pushed off-screen when the drawer was
open because the tab list shared flex space with it. Toggle now stays
visible at all times, anchored at the right edge of the tabs row, and
visually distinct from the tabs (vertical separator, lavender filled
state when active — no bottom-border indicator that would mistake it
for "another tab").
The drawer slides open/closed via a width transition (always rendered)
instead of popping in/out, and the resize divider floats over the
drawer's left edge so the toggle and drawer touch directly with no
flex-gap between them.
