v3.8.5 — Antigravity jobs would fail: Gemini 3.1 Pro left the catalog

Fixed — Antigravity jobs would fail: Gemini 3.1 Pro left the catalog

agy 1.3.4 dropped Gemini 3.1 Pro and added Gemini 4 Argon (Low, Medium, High). Our built-in Antigravity map still
routed frontier, deep and standard to Gemini 3.1 Pro, which agy now refuses (it prints its model list
instead of answering). Every Antigravity job and the arbiter's Gemini seat would have failed on a current agy.
The defaults are now Gemini 4 Argon (High) for frontier and deep, Gemini 4 Argon (Low) for standard and
Gemini 3.8 Flash (Low) for light; each answered a live agy --print probe on 2026-10-14. A project that pinned
Gemini 3.1 Pro in .claude/compound-v.json must re-run /v:models.

Fixed — /v:models read every unfamiliar Gemini model as the cheap tier

The Antigravity ranker looked for the substring mini to spot small models, and "Gemini" contains it. Any
Gemini line without Pro in its name was ranked with Flash; on the new catalog /v:models proposed
Gemini 4 Argon (Low) for light and left 3.8 Flash out. Tier words are now matched as whole words after the
family name (ultra, pro; flash, spark, mini, lite, nano), and an unknown tier name such as Argon
counts as strong. On the live catalog the proposal is now Argon High / Argon High / Argon Low / 3.8 Flash Low.
