Fixes#61476
Untagged text blocks in mixed assistant messages were forced to undefined
phase when any sibling had an explicit textSignature phase. Now they
correctly inherit the message-level assistantMessagePhase, preventing
commentary leaks during history replay.
Removes the hasExplicitBlockPhase scan — untagged blocks always inherit
m.phase. Blocks with explicit textSignature.phase still use their own.
94/94 tests pass. Regression test added for mixed explicit/untagged blocks.
* fix(msteams): add SSRF validation to file consent upload URL
The uploadToConsentUrl() function previously accepted any URL from the
fileConsent/invoke response without validation. A malicious Teams tenant
user could craft an invoke activity with an attacker-controlled uploadUrl,
causing the bot to PUT file data to arbitrary destinations (SSRF).
This commit adds validateConsentUploadUrl() which enforces:
1. HTTPS-only protocol
2. Hostname must match a strict allowlist of Microsoft/SharePoint
domains (sharepoint.com, graph.microsoft.com, onedrive.com, etc.)
3. DNS resolution check rejects private/reserved IPs (RFC 1918,
loopback, link-local) to prevent DNS rebinding attacks
The CONSENT_UPLOAD_HOST_ALLOWLIST is intentionally narrower than the
existing DEFAULT_MEDIA_HOST_ALLOWLIST, excluding overly broad domains
like blob.core.windows.net and trafficmanager.net that any Azure
customer can create endpoints under.
Includes 47 tests covering IPv4/IPv6 private IP detection, protocol
enforcement, hostname allowlist matching, DNS failure handling, and
end-to-end upload validation.
* fix(msteams): validate all DNS answers for consent uploads
* fix(msteams): restore changelog header

Fixes#61377
The provider attribution code only recognized api.x.ai as the xAI-native
endpoint. Some users have api.grok.x.ai configured (or it appears in
certain DNS/config scenarios) which would not resolve as xAI-native,
causing web_search tool failures.
This change adds api.grok.x.ai as an alias for xAI-native endpoint
classification alongside api.x.ai.
When gateway.tls.enabled is true, gateway status probes now target local loopback/tailnet over wss and pass the local TLS fingerprint for localLoopback probes. This avoids false unreachable results for healthy local TLS gateways.

After a SIGUSR1 in-process restart following an npm upgrade from v2026.4.2
to v2026.4.5, the globalThis singleton created by the old code version
lacks the activeTaskWaiters field added in v2026.4.5. resolveGlobalSingleton
returns the stale object as-is, causing notifyActiveTaskWaiters() to call
Array.from(undefined) and crash the gateway in a loop.
Add a schema migration step in getQueueState() that patches the missing
field on legacy singleton objects. Add a regression test that plants a
v2026.4.2-shaped state object and verifies resetAllLanes() and
waitForActiveTasks() succeed without throwing.
Fixes#61905
The plugin loader cache key included runtimeSubagentMode, which is
derived from allowGatewaySubagentBinding. Since different call sites in
the message processing pipeline pass different values for this flag,
each call produced a distinct cache key, triggering redundant
register() calls (40+ in 24 seconds after startup).
runtimeSubagentMode does not affect which plugins are loaded or how
they are configured — it is only metadata stored alongside the active
registry state. Removing it from the cache key lets all call sites
share the same cached registry regardless of their binding mode.
Fixes#61756
