## Summary
`ProxiedCopilotRuntimeAgent` builds its `IntelligenceAgent` delegate
**once** and caches it for the proxy's lifetime, copying `headers` into
the delegate's constructor config. Nothing ever refreshed that copy, so
**a header that changed after the delegate was created never reached
`/connect` or `/run`** — for the life of the agent.
For a multi-tenant app carrying the active tenant in a header, the join
was attempted under the *previous* tenant's identity with the *new*
tenant's thread id, and the platform correctly answered
`THREAD_NOT_FOUND`. Only a full page reload cleared it, because that
rebuilds the delegate. A rotated or refreshed `Authorization` bearer has
the same exposure.
Reported by Sameday against 1.67.1 with a deterministic staging repro:
```
19:45:23.554 | /copilotkit/runtime/threads | hdr=<tenant B> | 200
19:45:23.886 | /copilotkit/runtime/threads/subscribe | hdr=<tenant B> | 200
19:45:23.893 | /copilotkit/runtime/agent/<id>/connect | hdr=<tenant A> | body.companyId=<tenant B> | 404
```
`/threads` carries **B** while `/connect` carries **A**, ~340ms apart in
the same switch. Not a race — a stale copy with no refresh path.
## Root cause
`setHeaders` / `applyHeadersToAgent` could not fix this: they write an
agent's `.headers`, and `IntelligenceAgent` exposed only `private
config`. `syncDelegate` *looks* like the refresh path, but its
`hasHeaders` probe is `"headers" in agent` — false for the delegate,
since `headers` is declared on `HttpAgent`, not on `AbstractAgent`. So
`config.headers` was the sole header source for Intelligence REST calls,
with no refresh path at all.
## The fix
Expose `headers` as a public accessor pair backed by `config`, and read
it in `requestJoinCredentials$`.
**The accessor is the entire fix**: it makes `hasHeaders` true, so
`syncDelegate` — which already runs on every `resolveDelegate()`, and is
preceded by `applyHeadersToAgent` in `RunHandler.connectAgent` — starts
actually refreshing the delegate before each join. No new plumbing.
Two things worth flagging for reviewers:
1. **The originally-suggested fix ("make `requestJoinCredentials$` read
live headers") does not work on its own** — and is actively harmful.
There was no live header source on the class to read: without the
accessor, `this.headers` is `undefined` and **every header is dropped**
(verified: only `Content-Type` survives). The read here goes through the
accessor for a single source of truth, not because that read carries the
fix.
2. **The setter replaces the config object rather than mutating it**,
because `clone()` shares the config reference. The join path alone would
mask an in-place write (`syncDelegate` rewrites headers just before
every join), but the credential re-acquisition inside a running pipeline
(`intelligence-agent.ts:563`) does not re-sync — so a clone's tenant
could ride out on the original's socket-error refresh. That's the same
cross-tenant leak this accessor exists to prevent.
`credentials` had the identical defect via `config.credentials`
(`hasCredentials` was false too) and gets the same treatment.
## Testing
**Unit tests (5 new, each written first and watched fail).** The pre-fix
failure is the staging symptom reproduced:
```
FAIL > sends a header changed after the delegate was created
AssertionError: expected { …(2) } to match object { 'X-Tenant': 'tenant-b' }
- "X-Tenant": "tenant-b",
+ "X-Tenant": "tenant-a",
```
Coverage: a header changed post-construction reaches `/connect`; the
same on the `/run` path (which was independently verified broken
pre-fix, sending tenant A where B was expected); credentials likewise; a
clone's header update must not reach the original
(`IntelligenceAgent.clone()` invariant — this one fails under in-place
config mutation); and a per-thread clone and its original each send
their own tenant.
**Verified beyond the unit tests.** Because the mocked-harness result
alone doesn't prove the production wiring, I drove the real chain —
`CopilotKitCore.setHeaders` → registry → proxy → delegate → outbound
POST — in a plain Node process with no vitest and no `vi.mock`, stubbing
only `fetch` at the network boundary. Same script against the unfixed
file, then the fix:
```
BEFORE (origin/main) AFTER (this PR)
"headers" in delegate: false "headers" in delegate: true
delegate.headers: undefined delegate.headers: { X-Tenant: tenant-b }
proxy.headers after setHeaders(B): proxy.headers after setHeaders(B):
{ X-Tenant: tenant-b } { X-Tenant: tenant-b }
0: POST /connect X-Tenant=tenant-a 0: POST /connect X-Tenant=tenant-a
1: POST /connect X-Tenant=tenant-a <-- 1: POST /connect X-Tenant=tenant-b credentials=include
FAIL (stale headers) PASS (live headers reach /connect)
```
The "before" column reproduces the report's tell exactly:
`proxy.headers` correct at tenant B while `/connect` still sends tenant
A, through the very API the report found ineffective.
**Gates** (run in a worktree with a freshly built `@copilotkit/shared`,
since a stale dist otherwise produces 20 unrelated
`core-inspector-metadata` failures and 4 `tsc` errors):
| Gate | Result |
| --- | --- |
| `@copilotkit/core` vitest | **654 passed / 654**, 59/59 files |
| `tsc --noEmit` | clean |
| `oxlint` | 0 errors (2 warnings, both pre-existing test helpers) |
| `oxfmt` | no reformatting needed |
**Not covered:** `fetch` is stubbed, so this does not exercise a live
Intelligence gateway or a browser tenant switch — it proves the outbound
header is correct, not the platform's response to it.
## Note for whoever merges
#6450 and #6468 also touch `intelligence-agent.ts` (thread-restore work)
but neither goes near the header path, so conflicts should be textual at
worst.
## Follow-up left out of scope
Two separate pre-existing defects surfaced while verifying this one.
Neither is touched here.
**1. `credentials` passed to a `ProxiedCopilotRuntimeAgent` constructor
are dropped at registration.** `applyCredentialsToAgent` overwrites
`agent.credentials` from core unconditionally, with no per-agent
baseline — unlike `applyHeadersToAgent`, which merges over the
`agentOwnHeaders` baseline captured for exactly this reason (#5635).
Probed in a real process: an agent constructed with `credentials:
"include"` in a core with none configured reports `undefined`
immediately after registration, and every join goes out without
credentials. Identical before and after this PR, so it is not a
regression from this change — but the headers/credentials asymmetry
looks unintended, given #5433 was specifically about preserving proxied
runtime credentials.
**2. `buildRuntimeUrl` reads `config.agentId`
(`intelligence-agent.ts:770`), (`intelligence-agent.ts:770`), so
`syncDelegate`'s `delegate.agentId = routedAgentId()` is cosmetic for
the REST URL. Same root-cause class as this bug, but latent rather than
live (routing is fixed per proxy instance).
Happy to file both separately.

The per-thread-clone test's comment claimed it guards the copy-on-write
setter. It does not: syncDelegate rewrites headers before every join, so
it passes even with an in-place write (verified). Say what it actually
pins — each proxy's joins carry its own tenant — and point at the
clone-invariant test that does guard the setter.
Also assert the pre-change join carried no credentials, so the
credentials test shows a transition rather than a single end state.
The report names both /connect and /run. The run path reaches the
delegate through #runViaDelegate, which shares resolveDelegate with the
connect path, so the accessor fixes both — but that was inferred from the
shared call site rather than pinned. Verified failing against the
pre-fix file (sent tenant-a where tenant-b was expected).
`ProxiedCopilotRuntimeAgent` builds its `IntelligenceAgent` delegate once
and caches it for the proxy's lifetime, copying `headers` into the
delegate's constructor config. Nothing ever refreshed that copy, so a
header that changed later never reached `/connect` or `/run` — for the
life of the agent.
`setHeaders`/`applyHeadersToAgent` could not fix it: they write an
agent's `.headers`, and `IntelligenceAgent` exposed only `private
config`. `syncDelegate` looked like the refresh path but its `hasHeaders`
probe is `"headers" in agent`, which was false for the delegate.
Multi-tenant apps that carry the active tenant in a header saw the join
attempted under the previous tenant's identity with the new tenant's
thread id, answered THREAD_NOT_FOUND. A rotated `Authorization` bearer
has the same exposure. Only a full reload cleared it.

`requestJoinCredentials$` to read live headers, as the report suggested,
does nothing on its own: there was no live source on the class to read,
and without the accessor `this.headers` is `undefined`, which drops every
header. It reads through the accessor here for a single source of truth,
not because that read carries the fix.

switch still sent tenant A; after, it sends tenant B.

## What does this PR do?
Adds the CopilotKit consumer side of ENT-1173 across Shared, Runtime,
Core, Web Inspector, and the existing Shell Docs pages.
- Defines and parses optional trusted Inspector metadata for identity,
plan, license, action, usage, and expiry. Runtime proxies it through a
private, failure-isolated route, and Core refreshes it without changing
connection state.
- Groups Inspector navigation into Threads, Agents, and Learning.
Threads renders finite, unlimited, unknown, overage, and expiring usage
states plus matching trusted plan or license actions.
- Keeps explicit `threadEndpoints` as the only authority for Thread
requests. Locked or absent capability states make no list, subscription,
detail, message, event, or state calls.
- Keeps the zero-thread video, three example Threads, detail tabs, and
guided tour in empty and locked states. General Intelligence remains the
default onboarding path; only trusted `team_self_hosted` metadata uses
self-hosted onboarding.
- Gives an active license with missing Runtime routes a short **Finish
setting up Rich Threads** state. Users can copy a safe coding-agent
prompt or open the public Runtime setup guide. The same copy control
appears in that guide, and raw Markdown/LLM views include the full
prompt.
- Keeps finite usage green below 90%, orange from 90% to the limit, and
red at or above the limit. At 90%, a trusted plan action changes from
**Manage Your Plan** to a purple **Upgrade Your Plan** without changing
its trusted URL, action kind, or telemetry contract.
- Adds a deterministic 33-state loopback lab for CopilotKit developers.
It has no production route or export, is absent from public docs and
package metadata, and is excluded from the npm tarball.
`Expiring Soon` is display-only; this PR does not enable the thread
culler. Managed Enterprise receives no manage-plan action, and Team
Self-Hosted receives no hosted plan action. Optional metadata and the
additive expiry field remain compatible across mixed producer, Runtime,
Core, and Inspector versions.
A small Channels test-only change updates fetch mocks for current
TypeScript types. It changes no Slack or Teams docs or runtime behavior.

#6296 preserved the logical run id across a HITL resolve by pinning the
originating id on the follow-up's agent invocation. That fixed#3456 (external
tracing saw one logical run split into two halves), but pinning it on the WIRE
made the transport treat the follow-up as a resumption of a run it had already
finished. It re-delivered that run's already-applied half — duplicating every
tool call on the message, each duplicate carrying empty arguments, since a start
event has none and the TOOL_CALL_ARGS deltas that follow are addressed to the
first copy — and the follow-up's own tool call never reached client state, so
its card never rendered.
In the reskinnable-demo banking skin that broke teach mode outright: the agent
called awaitDashboardDemonstration, the server emitted TOOL_CALL_START for it,
and the live "Recording your workflow" card never appeared, leaving no way to
finish or save the demonstration.
#6296's goal is kept, moved one layer up. The continuation is registered against
the originating id (markNextRunAsContinuation already took an expectedRunId
parameter, previously unused) and the state manager re-stamps the continuation's
events onto it. State/message association and external tracing still see ONE
logical run; the wire is simply allowed to identify the invocation honestly.
Nothing from #6296 is reverted.
core-follow-up's run-id test asserted the mechanism (both invocations carry the
same wire id), which this deliberately changes, so it now asserts the goal: the
originating id is pinned on the first invocation and the follow-up leaves it to
the transport. Its sibling assertion — the thread still knows exactly one run —
was already there and still passes untouched. A new StateManager test covers the
re-stamp directly; verified red before green by dropping the expectedRunId
lookup.
Verified in the browser against a live Intelligence stack: before, the recording
card never rendered; after, it renders with its REC indicator and I'm done /
Cancel controls. `@copilotkit/core` 58 files and `@copilotkit/react-core` 123
files pass.

## 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

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.
