Feature Request

The /admin/analytics dashboard shows zero token usage for models used exclusively via API clients (OpenCode Desktop, Continue.dev, curl). Models used from the Web UI browser show correct analytics.

Related to: #23917 (Bug 6)

Root Cause

The analytics pipeline requires event_emitter to be non-None, which requires chat_id, session_id, and message_id. API clients don't send these -- they manage their own conversation state.

When event_emitter is None, the streaming handler falls to a simple passthrough branch with NO usage tracking and NO DB writes. The usage data IS present in the SSE stream but nobody reads it.

Path	chat_id	event_emitter	Usage Tracked	DB Write
Web UI browser	Set by frontend	Non-None	Yes	Yes
API client	None	None	No	No

Suggested Fix

In the passthrough branch, extract usage from the final SSE chunk and write to DB:

else:
    async def stream_wrapper(original_generator, events):
        usage = None
        async for data in original_generator:
            if isinstance(data, str) and data.startswith('data: '):
                try:
                    chunk = json.loads(data[6:])
                    if chunk.get('usage'):
                        usage = normalize_usage(chunk['usage'])
                except (json.JSONDecodeError, ValueError):
                    pass
            yield data
        if usage and metadata.get('user_id'):
            # Write usage to DB even without chat_id
            ...

Impact

Web UI: None (already has full analytics)
API clients: Token usage tracked for cost monitoring
