## Summary
Preserve the logical run ID when a legacy `useCopilotAction({
renderAndWaitForResponse })` frontend tool resolves and
`processAgentResult` starts its recursive follow-up.
The run handler binds each internal continuation handoff to the exact
follow-up invocation, cancels it when setup fails or no run starts, and
keeps the handoff out of the public `CopilotKitCore.runAgent` contract.
The public regression drives the legacy hook through its
`useHumanInTheLoop` and `useFrontendTool` path, renders the approval
control, resolves it, and verifies both agent calls use the same
generated ID.
Closes https://github.com/CopilotKit/CopilotKit/issues/3456
## Changes
- Preserve the originating ID across recursive frontend-tool follow-up
runs
- Keep the existing legacy HITL registration and response behavior
unchanged
- Add core follow-up coverage and a public `useCopilotAction` regression
- Retain the existing standard/legacy interrupt and StateManager
coverage from the earlier fix

Realigns the inspector/memory work onto the banking demo as it shipped in
#6136 (ChatGPT-style shell, gen-UI beats, durable-memory self-learning) and
#6202 (README refresh).
All six conflicts were the same collision: this branch removes the bespoke
Glass Engine inspector, while #6136 kept and rebuilt around it.
- run-handler.ts: kept both sides (our CopilotKitCoreCatalogComponent and
main's MAX_FOLLOW_UP_DEPTH landed at the same spot).
- wrapper.tsx / layout.tsx: took main's rewritten provider tree and
right-hand icon rail, minus the Glass Engine providers, pane, and
telescope toggle. Also dropped main's `padClass` (it reserved space for
the Glass pane and referenced a now-removed `glassActive`) and
`<ProactiveNotice />` (main removed it; the import is already gone).
- memory-tab.tsx, lib/intelligence/memory.ts: confirmed the deletions.
Their only remaining importers were the bespoke inspector and the
banking-local /api/memories routes, all removed here. seed-memories.ts
is unaffected: it POSTs to INTELLIGENCE_API_URL, not the local route.
- README.md: kept our product-inspector section over main's Glass Engine
availability/activation prose, and documented the Capabilities tab.
Drive-by fixes to comment rot the migration created: user-id.ts and the
copilotkit route doc comments referenced the deleted Memory-panel proxies,
and the README pointed the presenter-reset control at the removed
telescope toggle.
Also replaces a literal NUL byte in capabilityKey() with a unicode escape.
The raw control character made tsc/grep/diff treat run-handler.ts as a
binary file, which hid this very merge's conflict markers from grep.
Behavior is unchanged.

## What does this PR do?
Fixes credential forwarding for `ProxiedCopilotRuntimeAgent` on the
default
REST/auto transport.
The single-route transport already adds `this.credentials` to its
`RequestInit`, but the REST `run` and `connect` paths rely on
`HttpAgent.requestInit(input)`. That base initializer does not know
about the
proxy agent's `credentials` property, so cross-origin runtime requests
fall
back to the browser default and drop cookie auth.
This PR overrides `requestInit()` on `ProxiedCopilotRuntimeAgent`,
preserves the
base request init, and adds `credentials` when configured. The existing
transport matrix tests now assert that both `run` and `connect` requests
include
`credentials: "include"` for REST and single-route transports.

## Summary
Fixes#4819.
`processAgentResult` recurses into `runAgent` whenever `needsFollowUp`
is true, with **no depth limit, no circuit breaker, no duplicate
detection**. Any scenario that keeps `needsFollowUp = true` loops
forever:
- The LLM repeatedly calling the same tool
- The backend returning a `RunError` after receiving tool results
(#2416)
- Input processors reprocessing tool messages (#3044)
This silently consumes API quota and can DOS the backend. The only
existing workaround — setting `followUp: false` on a tool — is too blunt
and breaks legitimate multi-step workflows.
## Change
- Add an absolute safety cap `MAX_FOLLOW_UP_DEPTH = 100`, reusing the
existing `_runDepth` counter (incremented in `runAgent`, decremented in
its `finally`).
- In `processAgentResult`, when the depth cap is reached: stop
recursing, emit a `logger.warn` (for debuggability), and return the
current result normally (already-inserted tool messages are preserved).
- The cap is deliberately high so legitimate multi-step workflows
(search → fill form → confirm → update → send email) are never affected;
it only trips on runaway recursion.
This protects against **all** infinite-loop scenarios in the issue, not
just specific triggers, without requiring users to set `followUp:
false`.
## Test
- Added `core-full.test.ts` TEST 9b: an agent that always returns a
fresh tool call (so `needsFollowUp` stays true). Asserts the run
terminates, `runAgent` is capped at ≤100 calls, and a warning is
emitted.
- `nx run @copilotkit/core:test` → 40 files / 431 tests pass.
- `nx run @copilotkit/core:build` → success.
Fixes#5966. Follow-up to #5812 / #5885.
## Problem
After #5885 stopped the post-terminal `TEXT_MESSAGE_END` crash, pressing
**Stop** no longer breaks the chat — but for an agent that emits a
terminal `RUN_ERROR` (code `abort`) as its cancellation signal (e.g.
pydantic-ai's `AGUIAdapter`), the client still surfaces that as an
**error banner** ("This operation was aborted"). A user-initiated stop
is expected cancellation, not a failure.
Traced path (no abort suppression at any hop):
`RUN_ERROR(code:"abort")` → `RunHandler.onRunErrorEvent`
(`run-handler.ts`) → `emitAgentError(AGENT_RUN_ERROR_EVENT)` → `onError`
→ CopilotChat/react-ui `triggerChatError` → banner. The only existing
abort suppression is for the *local* fetch-abort rejection
(`run-handler.ts:318`), a different path.
## Fix
Suppress the error emission in `onRunErrorEvent` when the run was
user-aborted — mirroring the local-abort suppression already on the
`runAgent`/`connectAgent` paths:
```ts
const runWasAborted = this._runAbortController?.signal.aborted === true;
if (runWasAborted || event?.code === "abort") {
return;
}
```
Prefers the client's own `_runAbortController.signal.aborted` (robust —
the agent-supplied `code` isn't standardized across agents; the
`code:"abort"` in the repro comes from the agent, not CopilotKit) with
`code === "abort"` as a secondary signal. Normal `RUN_ERROR`s are
unaffected.
## Testing
- **TDD** (`core-error-handling.test.ts`): two new tests fail pre-fix
and pass after —
- agent emits `RUN_ERROR` code `"abort"` → no `AGENT_RUN_ERROR_EVENT`
surfaced.
- run user-aborted mid-stream (via `agent.abortRun()`, which RunHandler
intercepts to abort the controller) → a subsequent `RUN_ERROR` with a
*non-abort* code is still suppressed (exercises the `signal.aborted`
path).
- The pre-existing test — normal `RUN_ERROR` (code `"bad_request"`)
still emits `AGENT_RUN_ERROR_EVENT` — continues to pass (control against
over-suppression).
- Full `@copilotkit/core` suite green: **578/578**. `tsc` 0 errors;
`oxlint` 0.
Note: this is a UX/product call (a user Stop shouldn't render as an
error). Suppressing in core fixes it for both the default chat banner
and app-level `onError` handlers; the run lifecycle still reflects the
termination.

The reported bug (capabilityKey joining agentId+name with a SPACE) is NOT
present: run-handler.ts already joins with a NUL byte (0x00), matching the
"NUL-separated" docstring. The space appearance was a rendering artifact —
a NUL byte displays as an invisible/space-like gap in editors and grep.
This adds the mandatory covering regression test so a future edit back to a
space separator cannot regress silently. It registers two agent-scoped tools
whose (name, agentId) pairs collide under a space separator but are distinct
under NUL — A {name:"b c", agentId:"a"} and B {name:"c", agentId:"a b"}, both
"a b c" with a space — disables only A, and asserts B stays enabled in
isToolEnabled and buildFrontendTools. Red/green verified: fails against a space
separator, passes against the shipped NUL separator.
capabilityKey callers (setToolEnabled/isToolEnabled/buildFrontendTools) are all
internal and all rely on this collision-free identity.

Parse optional projectJoinToken/projectJoinCode from /memories/subscribe.
When present, open a second project_meta:memories:<code> realtime channel
alongside the user channel, feeding the same id-keyed reducer. Both channels
share the same session stamp so the reducer's superseded-context guard drops
stale deltas from both identically (the D4 landmine). Absent project creds ->
user-only, silent degrade, realtimeStatus unaffected.
Remove the user-scope snapshot filter now that project rows stay in sync via
the project channel, and invert the snapshot test to expect project rows.
