A terminal event that arrives with an empty output was rebuilt from delta
accumulation. BufferedResponseAccumulator models only one reasoning item, one
message, and N function calls, and records no item id, status, or phase, so a
turn carrying several items collapsed into a single fabricated message: the
reasoning item disappeared, the real message id was replaced, and phase was
lost.
reconstructResponseOutputFromSSE already prefers the raw output_item.done
items over accumulation for buffered responses. The streaming path had no
equivalent because it never sees the whole body at once. Collect the raw item
of each output_item.done keyed by output_index and rebuild from those, falling
back to accumulation only when the stream reported no done item at all.
Items are stored as raw JSON, so vendor extensions and item types this gateway
does not model survive the rebuild verbatim.

ConfigManager.refreshLoop reloads the Prompt Guard config every 5s and
Reload logged config_loaded on every successful load, so an unchanged
config produced up to ~17k identical lines per instance per day and
buried real configuration changes.
Log the event only when the reload carries news: the first snapshot, a
new config version (every admin save bumps it under the advisory lock in
UpdateConfig), a flip of the global risk control gate (a separate setting
that leaves the version untouched), or a recovery from a failed reload so
the degraded-to-healthy transition stays visible.
This mirrors logInvalidTokenEndpoints, which already warns once per
change rather than on every refresh.
CN-provider accounts explicitly configured with api_protocol=anthropic
(the frontend offers per-provider presets such as GLM Anthropic) fell
through the account-test router to the generic Claude tester, which:
- appended ?beta=true, which the native passthrough deliberately avoids
for third-party Anthropic endpoints, and
- defaulted a missing base_url to https://api.anthropic.com — sending
the provider's API key to Anthropic instead of the provider's own
Anthropic-compatible endpoint (guaranteed 401 plus cross-provider
credential exposure).
Route them to a dedicated probe that mirrors the adaptive Anthropic
check: resolve the endpoint via GetAnthropicProtocolBaseURL (same
resolution as real /v1/messages forwarding, including per-platform
defaults), use the shared API-key auth header, and mark 401/403 as the
account error state.
Also fail fast with an actionable hint when the anthropic-protocol
base_url still points at an OpenAI-compatible endpoint (paas path,
version segment, or chat/completions suffix): the naive {base}/v1/messages
join would 404 (e.g. /api/paas/v4/v1/messages) without any pointer to
the actual misconfiguration.
