Tests cover tiered models, thinking-level propagation, limits, and stale discovery responses. ChangesAntigravity wire routing
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The change makes model discovery follow the authenticated live catalog, but stale catalog mappings may remain usable briefly after that catalog is revoked, which could expose or route requests to unavailable models. The PR is mergeable with explicit owner awareness and follow-up for cache invalidation. Sequence Diagram(s)sequenceDiagram

- Line 1364: Move the registerAntigravityDiscoveredWireModels call so it
executes only after setCached successfully accepts the current discovery
generation; ensure rejected stale results publish neither catalog data nor wire
mappings.
In `@src/providers/antigravity-models.ts`:
- Around line 370-371: Update the deduplication check in the model parsing flow
around baseId so it matches only the exact base ID, the current tiered ID, or
supported low, medium, and high effort-tier IDs; do not treat arbitrary IDs
beginning with baseId- as tiers, preserving valid siblings such as image models.
- Around line 446-449: The discovered-model return path in
discoveredAntigravityWireModelId must also apply the tiered-model thinkingLevel
rule before returning. Preserve the requested high effort for a display-derived
gemini-3.7-flash picker ID mapped to gemini-3.7-flash-tiered, while retaining
existing behavior for non-tiered models; add a regression test covering this
mapping and returned thinkingLevel, including the provider/adapter contract
checks required for src changes.

- Line 1377: Update registerAntigravityDiscoveredWireModels and the
clearModelCache invalidation flow so discovered wire mappings are bound to the
provider catalog generation or removed when that generation is cleared; ensure
stale mappings cannot resolve after cache invalidation. Extend the
stale-discovery test to register a mapping, clear the cache, and assert
resolution no longer returns the former wire ID, including the required
provider/adapter contract-drift checks.
