* sessions: hide session picker groups when no duplicate session names
Section headers in the session type picker exist to disambiguate session
types that share a label across providers (e.g. two providers both
offering "Claude"). When every type's label is unique there is nothing
to disambiguate, so render a flat list without group headers even when
multiple providers contribute.

* sessions: rename Copilot CLI session type label to "Copilot"
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* test: update Agents Window smoke test for renamed Copilot label
The Copilot CLI session type label was renamed to "Copilot" (shared
CopilotCLISessionType used by the Copilot Chat provider), so the picker
no longer exposes a "Copilot CLI" entry. Select "Copilot" instead.

The Chat Sessions smoke test runs right after the Chat Disabled suite,
which disables AI features. When the suite re-enables them, there is a
brief window where copilot-chat is still disabled and its commands are
not yet registered. The smoke helper invoked
'github.copilot.debug.extensionState' to force-activate copilot-chat,
but that executeCommand rejected with 'command not found' during this
window, aborting the handler before it could open the chat editor and
causing a 60s timeout on '.editor-instance .interactive-session'.
Wait for the diagnostic command to be registered (via the existing
waitForCommand helper) before invoking it, so the handler no longer
races copilot-chat enablement/activation.

The "Agents Window > Test Copilot CLI session" smoke test flakily timed
out at `activateSessionByLabel`, which located the just-completed session
row by its title and expected it to equal the mocked reply
`MOCKED_COPILOT_RESPONSE`. That title is set asynchronously by a utility
model after the first turn and races the untitled->committed session
swap, so it is non-deterministically either the user's prompt (the
synchronous fallback) or the generated reply. The test passed on macOS
(title-gen landed) and failed on Linux (it didn't) in the same run.
Decouple row identification from response verification:
`activateSessionByLabel` now accepts one or several row substrings and
matches a row containing ANY of them, while a separate `responseLabel`
is verified against the active session's response bubble. The smoke test
passes both the first prompt and the reply, so activation is
deterministic regardless of when title generation completes.

The local agent host runs a single sessions provider whose session cache
holds every agent-host session type (codex, claude, copilot). When a new
session is sent, the provider identifies the freshly-committed backend
session in `_waitForNewSession` purely by novelty — the first cached
session whose raw id was not present before the send. The session's
type/scheme was never checked.
That is wrong when a session of a *different* type appears in the cache
during the send. A slow Codex session (which cold-starts a native
app-server before its first /responses turn) sent while a Claude session
from an earlier run is present would latch onto the Claude session and
return it as the Codex commit. `sendRequest` then reports an
"active session replaced: codex -> claude", the workbench swaps the
active slot to the wrong session, removes the Codex one, and the Codex
reply renders nowhere. A claude harness that is suppressed in the current
window (preferAgentHost=false) additionally throws "Agent host targets
must have an item provider" when activated. This is exactly why the
Codex smoke test timed out on the Windows CI runner (where the cold-start
race is widest), failing build 449022.
Filter `_waitForNewSession` by the `chatResource` scheme so a send only
ever commits a session of its own type, in both the immediate cache scan
and the onDidChangeSessions wait. Re-enable the Codex smoke test that was
disabled in #321983 to keep the build green.
Verified: a new unit test reproduces the cross-type latch (fails before,
passes after); live launch with stale claude sessions present shows the
Codex session stays active with no wrong swap; and the (re-enabled) Codex
smoke test passes locally end-to-end.

* Get tests passing
* CCR feedback

* Undo chatView.ts changes
* Missing Claude warm up
The Codex smoke test previously could only skip: when the Codex session
type WAS available, the agent host's shared CopilotApiService discovered
CAPI endpoints by calling a hardcoded `api.github.com/copilot_internal/user`,
which 401s with the fake smoke token (the other harnesses avoid this —
Copilot CLI uses the @github/copilot SDK pointed at COPILOT_API_URL, and
the renderer-side Claude test uses the extension token manager). So no
agent-host model path had ever been mocked.
- copilotApiService.ts: honor a test-only `VSCODE_AGENT_HOST_CAPI_URL_OVERRIDE`
env. When set, skip the api.github.com discovery and route every CAPI
request (models/responses/messages) at the override. Never set in
production, so per-token discovery is unchanged.
- agentsWindow.test.ts (setupAgentHostSuite): set that override to the mock
server URL, so the codex harness's model list + /responses traffic reach
the mock.
- agentsWindow.ts (isSessionTypeAvailable): the picker dropdown is a one-shot
snapshot, so a provider that registers a few seconds after load (codex
spawns a native app-server first) was missed when the dropdown opened too
early. Re-open the dropdown on each poll and use a generous timeout so the
gate reliably runs when codex is present and only skips when it is absent.
Verified locally end-to-end: with codex available the test selects Codex,
the real app-server drives a turn through the proxy to the mock /responses
endpoint (codex's native payload), and MOCKED_CODEX_RESPONSE renders. With
codex unavailable it skips. 71 codex + 83 copilotApiService unit tests pass.

Adds an end-to-end smoke test for the codex harness that uses the REAL
codex app-server and fakes only the LLM. It reuses the existing
Agents-Window smoke harness, which already drives:
real Agents-Window UI -> agent host -> real spawned `codex` binary ->
real CodexProxyService -> mock LLM server
The mock LLM server (scripts/chat-simulation/common/mock-llm-server.ts)
already speaks codex's OpenAI `/responses` API and ships a
`gpt-5.3-codex` `/responses` chat-default model, so no LLM-side changes
are needed.
- test/smoke/.../agentsWindow.test.ts: new `Agents Window (Codex)` suite
via the existing setupAgentHostSuite helper with
`chat.agentHost.codexAgent.enabled` (codex is off by default). The test
selects the `Codex` session type, submits a scenario prompt, and
asserts the mocked reply plus a `chat/turnStarted` frame in the AHP
transcript (proving the codex harness, not a renderer fallback, served
it). Adds a warmUpCodexModel helper mirroring warmUpClaudeModel.
- test/automation/src/agentsWindow.ts: new isSessionTypeAvailable(label)
used to skip gracefully when codex isn't registered.
Codex only registers when its SDK is resolvable (product.agentSdks.codex
in packaged builds, or VSCODE_AGENT_HOST_CODEX_SDK_ROOT in dev); when
absent the test skips rather than fails.

* sessions: show provider names as section headers in session type picker
The session type picker (harness picker) showed provider names like
"Copilot Chat" and "Local Agent Host" as inline descriptors to the right
of the first row in each group, which read like a label on that row and
made it look like there were duplicate/broken entries.
Render the provider name as a proper section header above each group,
with a divider between sections, when more than one provider contributes
session types. Session types are grouped by their provider's display
label (preserving first-seen order) so each header is shown once even
when providers are interleaved or share a label. The same grouping is
applied to the mobile bottom-sheet variant.
Also rename the local provider label from "Local Chat" to "Copilot Chat".

* sessions: fix AgentHost smoke test selection and picker a11y for section headers
The session type picker now renders provider names as non-clickable
header rows. The smoke automation's selectSessionType matched the
provider label ("Local Agent Host") on an action row's inline group
title and clicked it; with headers that text is on a header row, so the
click did nothing and AgentHost sessions never started (CI timeouts).
- Update selectSessionType to select the first actionable row beneath a
matching section header, while still matching session type labels
directly on action rows.
- Include the provider label in the action item ARIA label when section
headers are shown, so same-named types (e.g. "Claude") are
disambiguated for screen readers since header rows are skipped by list
navigation.

* refactor: route turn access via defaultChat helpers
Adopt the multi-chat Agent Host Protocol: turns, active turn, steering,
queued messages and input requests moved off the session and onto a
per-chat channel. A single default-chat compatibility layer recombines
the session with its default chat so existing consumers keep working:
- Server (AgentHostStateManager) routes chat actions to the default chat
and exposes a merged ISessionWithDefaultChat view.
- Client (AgentHostSessionHandler) subscribes to both the session and its
default chat channel and merges them for reads.
- Widen action dispatch/emit signatures to SessionAction | ChatAction and
migrate turn/tool-call/input wire strings from session/* to chat/*.
- Update tests and mock connection to serve ChatState for default-chat
subscriptions and route chat actions accordingly.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* fix: repair chat retrieval and config regressions from multi-chat adoption
The multi-chat AHP adoption introduced two classes of regressions:
1. Chat retrieval/echo routing: chat actions now emit on the derived
default-chat channel, but several consumers were still keyed on the
session URI. Await both the session and default-chat subscriptions
before reading history, restore the chat channel on subscribe, forward
ChatActions, and normalize chat<->session URIs in dispatch/side-effects.
2. Session config loss: getSessionState() now returns a merged composite
copy (mergeSessionWithDefaultChat), and _ensureDefaultChat replaced the
live map entry with a clone. Callers mutating the returned object
(state.config = ...) stranded the mutation on a throwaway. Fix:
_ensureDefaultChat mutates in place to preserve createSession/
restoreSession return identity, and a new setSessionConfig() mutates the
live map object for the async restore path.
Tests migrated to setSessionConfig() where they previously seeded config by
mutating getSessionState() returns; duplicate-restore and client-echo tests
updated to reflect the two-channel (session + default-chat) model.
All agentHost node suites (409) and the browser contribution suite (148)
pass; typecheck and valid-layers-check are clean.

* chore: sync agent-host-protocol to d7f592e (chat interactivity)
Regenerates the vendored protocol/ from agent-host-protocol @ d7f592e,
which adds the optional `interactivity?: "full" | "read-only" | "hidden"`
metadata to `ChatState`/`ChatSummary` and the `ChatInteractivity` type.
Mechanical sync only (scripts/sync-agent-host-protocol.ts); no hand edits.

* refactor: preserve chat interactivity across summary/state helpers
Carries the new optional `interactivity` field through the VS Code glue
converters so it round-trips between `ChatState` and `ChatSummary`
(`createChatState`, `chatSummaryFromState`) and re-exports the
`ChatInteractivity` type alongside the other chat types.
Absence still defaults to "full", so single-default-chat sessions are
unchanged; this just stops the field being dropped during denormalization.

* test: route protocol integration tests through default chat channel
The multi-chat protocol adoption moved conversation contents (turns,
activeTurn, queued/steering messages, input requests) onto the session's
default chat channel, and renamed turn/tool-call/responsePart actions from
`session/*` to `chat/*`. The Protocol WebSocket integration tests still
subscribed only to the session channel and dispatched/awaited the old
`session/*` action types, causing notification timeouts and reads of
undefined turn arrays.
- Add `fetchSessionWithChat` helper that subscribes to both the session and
its default chat channel and returns the merged ISessionWithDefaultChat view
- Update turnExecution, sessionFeatures, sessionLifecycle, multiClient to read
turn/conversation state via the merged helper
- Rename stale `session/*` conversation actions to `chat/*` in clientTools,
toolApproval, turnExecution, and realSdkTestHelpers
- Subscribe secondary multi-client clients to the default chat channel
- Fix copilotRealSdk usage assertion to read turns from the default chat

* ci: add Node.js diagnostic reports for test crash investigation
Enable Node.js diagnostic reporting for the node.js unit test runner
so that native crashes (like the zlib crash in build 447204) produce
actionable diagnostic reports instead of a silent exit code 1.
Changes:
- Configure process.report in test/unit/node/index.js to write JSON
diagnostic reports to .build/crashes on fatal errors and uncaught
exceptions
- Add unhandledRejection handler (was missing, unlike Electron tests)
- Set NODE_OPTIONS in CI pipeline steps (win32, linux, darwin) with
--report-on-fatalerror and --report-uncaught-exception flags
- Reports are picked up by the existing crash-dump artifact collection

* fix: remove process.exit(1) from exception handlers
The uncaughtException handler intentionally does NOT exit — it logs
the error and lets Mocha continue running. The test suite has a
dedicated 'Errors' suite that asserts on collected unexpected errors
at the end. Calling process.exit(1) kills the test runner on the
first uncaught exception, failing all Electron tests on all platforms.
Keep the writeReport() calls for diagnostic purposes.

* fix: remove writeReport() from exception handlers
The manual writeReport() calls fire on benign unhandled rejections
(e.g. Canceled errors during test teardown in UserDataSyncService)
and block the event loop writing JSON reports to disk, causing
subsequent faked-timer tests to exceed their 2000ms timeout.
Report generation is already handled by process.report config and
NODE_OPTIONS flags (--report-on-fatalerror, --report-uncaught-exception)
which only fire on actual fatal errors, not on every caught rejection.

The NewChatInSessionsWindowAction keybinding (Ctrl+L) is gated on
the chat editor silently does nothing. This caused the 'Test Claude
session' and 'Test Local session' smoke tests to time out waiting for the
new-session view.
- Add `f1: true` to NewChatInSessionsWindowAction so it appears in the
command palette (only registered in the Agents Window context)
- Change `startNewSession()` in the automation helper to use
`quickaccess.runCommand()` instead of `dispatchKeybinding('ctrl+l')`,
bypassing the focus gate entirely

* Lots of logging for chat smoke tests
* PR test workflows: build extensions/copilot before smoke tests
* PR test workflows: drop duplicate copilot compile from linux/win32 (was already built before integration tests)
* smoke tests: remove musl Claude binary on Linux glibc runner
The musl variant is probed first by @anthropic-ai/claude-agent-sdk and
fails to exec on glibc (ENOENT from missing ELF interpreter), which
caused the Test Claude session tests to time out.
The Chat Sessions smoke tests wrote copilot-chat config keys before the
extension was installed in the ext host, triggering a 'not a registered
configuration' error dialog that blocked the UI and timed out the tests.
Add a waitForExtension helper that polls vscode.extensions.getExtension
and activates the extension, then call it before any config writes in
both openCopilotCliChat and openClaudeChat commands.
