Stable Release Anomaly Details

• Anomaly type: new
• Previous stable: 0.55.0
• Current stable: 0.56.0

This error signature is new in GitHub.copilot-chat 0.56.0 and did not appear in 0.55.0. It surfaces as an unhandled networkError (ERR_NAME_NOT_RESOLVED / ERR_INTERNET_DISCONNECTED / ERR_NETWORK_CHANGED) originating in the NES fetch path (Object.n [as fromUnknown] → bbr → ag._performFetch → provideNextEdit). These are user-connectivity failures that are currently escaping as unhandled errors rather than being caught and handled gracefully.

Affected buckets (same signature, coalesced into this issue)

Bucket	Users	Platform
b6664b01 (representative)	4737	win32
368bc58a	4441	win32
de00fa46	4279	win32
220d2689	2041	win32
98782794	2015	win32

Combined impact: ~17.5K users across 5 buckets.

Note: This is extension telemetry, so insider-build commit-range narrowing (last-good / first-bad / GitHub compare) does not apply.
