The CLI runtime emits `github.copilot.time_to_first_chunk` (seconds) on
chat spans, while the foreground extension uses
`copilot_chat.time_to_first_token` (ms). The SQLite store only checked
the foreground attribute, leaving ttft_ms NULL for CLI background agent
spans.
Add a `_ttftMs()` helper that coalesces both attributes with unit
conversion (seconds → ms) so the denormalized column is always populated.
Previously both cache hits and reused in-flight requests (async pending
or speculative) showed the database icon in the NES debug log. This
made it hard to tell whether a result was served from cache or joined
an existing stream.
Add a new \`reusedInFlight\` outcome with a git-merge icon ($(git-merge))
to visually distinguish 'joined an in-flight request' from 'loaded from
cache'. The database icon is preserved for true cache hits via
\`setIsCachedResult\`; reused in-flight requests now go through the new
\`setIsReusedInFlightResult\` method.
* agentHost: make 'new terminal' button open a terminal in the remote by default
Adds a new notion of 'default profile overrides' that the sessions app
uses to set the default terminal profile when a remote session is open.
* build
The CopilotAgent.getDescriptor() displayName was "Copilot" but should be
"Copilot CLI" to match the well-known CopilotCLISessionType label used
elsewhere. The remote agent host sessions provider uses this displayName
to build the session type label shown in the UI.

Only list Copilot SDK sessions that already have Agent Host session data, so sessions created by other Copilot CLI agents are filtered out without creating databases during listing.

* feat: upload commit-to-version mapping for copilot source maps
During the Copilot CI build, after uploading source maps to CDN, also upload
a small JSON file at sourcemaps/{extensionId}/commits/{commitHash}.json that
maps the VS Code commit hash to the patched extension version.
This enables the vscode-errors deminify service to resolve the correct
extension version for Insider builds, where the version is date-patched
(e.g. 0.44.2026041004) and not derivable from the repo alone.
* fix: use no-cache for commit-version mapping blob
The mapping file could change on pipeline reruns, so use
no-cache instead of long-lived cache headers.
* Move to InputState instead of metadata on sessions
Cleans up more old patterns with new patterns.

* Agents tunnels: auto-reconnect with backoff and wake-triggered retry
Tunnel-backed remote agent hosts previously had no auto-reconnect
behavior — on laptop sleep / network drop the tunnel would flip to
Disconnected and stay there until the user manually retried.
This adds a reconnect loop inside TunnelAgentHostContribution:
- Detect Connected→Disconnected transitions for still-cached tunnels
and schedule an immediate reconnect. Only fires when the entry is
explicitly Disconnected — if the entry has been removed (e.g. user
clicked "Remove Remote"), we honour the removal and do not reconnect.
- Exponential backoff on consecutive failures: 1s → 30s cap, up to
10 attempts, then pause.
- Wake-triggered retry: on browser `online` or tab
`visibilitychange` → visible, resume any paused reconnects.
Rate-limited to one resume per 10s so rapid tab toggling can't
hammer a permanently broken endpoint with unbounded attempt bursts.
- Prune all reconnect state when a tunnel is uncached or the
contribution is disposed.

* agentHost: fix bugs around message handling
- Fix a bug where a sessions were not restored correctly because they
had in-progress data (that is the move of the `providedSession.isCompleteObs?.get()`)
- Fix a bug where sessions that supported progress streaming would not
have sendable messages if they were already complete (that is the
addition of `this._pendingRequests.deleteAndDispose(model.sessionResource);`)
- Fix a bug in the agent host where we didn't provide `onDidStartServerRequest`
consistently which often prevented multi-client messaging from working
- DRY up some logic and add tests

* Top-align editor/detail back button to match section arrow
The .editor-header has align-items: center and contains a multi-line title
(name + filename), causing the 26px back button to drift down when centered
in the taller row. Pin it to flex-start so it sits at top of the padding
box, exactly where the section back arrow sits.

Follow-up to #310871: the sidebar entrypoint actions (Agents, Skills,
Instructions, Hooks, MCP Servers, Plugins) still called
selectSectionById after opening the editor, which deep-linked into
the section instead of showing the overview.

Adds a pure helper shouldKickOffBackgroundSummarization that gates the
post-render background compaction trigger based on prompt-cache warmth:
- inline + warm cache (toolCallRounds.length > 0): jittered threshold in
[0.78, 0.82) straddling the historical 0.80 edge.
- inline + cold cache: emergency kick-off at >= 0.90 to keep long-running
sessions from hitting sync foreground compaction.
- non-inline: unchanged >= 0.80.
The rng is injected via a private field so tests are deterministic and
the warm-only jitter path is exercised without touching Math.random.
Block the MCP servers and Plugins tabs in the chat customizations editor
when their respective access settings are disabled, including via
enterprise policy.
- McpListWidget watches `chat.mcp.access`; shows splash when value is
`none`. If `policyValue === 'none'`, shows policy-locked message and
hides the "Open Setting" button.
- PluginListWidget watches `chat.plugins.enabled` with the same
user/policy distinction.
- Reuse `.mcp-list-widget` root class so the new `.mcp-disabled-state`
CSS applies to both widgets via a single `.access-disabled` modifier.
- Add Dark/Light fixtures for both widgets in user-disabled and
policy-locked states (8 new screenshots).
