copilot: Auto — Copilot's own pick, the only choice a Student plan has — is listed for every Copilot account and works through magpie, as Copilot's clients do it (#256; Discord, CakeJskSUMM: Copilot Student can only use Auto) — Copilot's /models doesn't list Auto; its clients add it themselves (Copilot CLI 1.0.79: {id:"auto",name:"Auto"}, AUTO_MODEL_ID) and ask POST {api}/models/session with {"auto_mode":{"model_hints":["auto"]}} for a session_token, the selected_model and expires_at, each request then naming that model with the token in Copilot-Session-Token. magpie listed no Auto, failed an account whose list left nothing to pick by hand ("Copilot lists no chat model for this account"), and sent "auto" as a model. Now copilot_auto.go keeps the session per GitHub account, asked again two minutes before it expires; the gateway resolves Auto before choosing the API, so a picked model served only on /responses goes there; a body still naming "auto" (the model test) is rewritten; the endpoints of every model Copilot lists, hidden ones too, are kept for the picked one. A reply to "auto" from another model isn't counted as swapped (Cursor's auto too); the Copilot CLI's picker, which offers auto itself, leaves out the listed one. Tested with fakes in a sandbox HOME: provider/copilot_auto_test.go (a Student-like account whose models are all disabled lists [auto], the session body sent as above, requests carry the picked gpt-5-mini and the token, one session reused, renewed near expiry, an object-shaped selected_model, a refusal reported) and gateway/copilot_auto_test.go (a chat request for copilot/auto goes to /responses as gpt-5-mini with the token, two turns one session; fails without the gateway change); served_test gains the auto cases. go vet ./internal/..., go build -tags nogui (and GOOS=linux, GOOS=windows) and go test -tags nogui ./... pass. Not tried with a real Student account: what its /models returns, whether the plain session request suffices (Auto v2's /models/session/intent is not done), and the body is from VS Code's Copilot Chat, not captured traffic.
