Recommend exactly gemini-3.5-flash (default + mid) and gemini-3.1-flash-lite (lite); drop the product Pro/top suggestion and the "-latest self-tend" copy. Add an idempotent, lock-protected maint migration that byte-exactly pins the previously-curated moving flash aliases across the three restorable Google slots (active, remembered BYO, confidential prior-active), leaving gemini-pro-latest and any custom id untouched. Surface a persistent, config-derived Thinking advisory guiding the owner to choose an exact model whenever a slot still holds gemini-pro-latest. The -latest aliases remain family/pricing recognized since the vendor still serves them.
