Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughAntigravity’s model registry now exposes Claude Sonnet 5.5 and Opus 5.5 with low, medium, and high effort tiers. Routing selects suffixed wire IDs and maps retired Claude 4.6 IDs to the corresponding 5.5 model. Catalog and routing tests reflect these changes. ChangesAntigravity Claude 5.5 models

Mark the Antigravity base overlays as derived.
Line 375 and Line 379 use status: "verified", but their sources cite Anthropic list prices, not a confirmed Google Antigravity rate. The Antigravity pricing note at Lines 305-310 uses verified-derived when CCA billing equivalence is unpublished. src/usage/cost.ts, Lines 252-314, passes the overlay status to downstream consumers. Set both rows to verified-derived.

Selectively adapts pricing from source PR lidge-jun#6497 at 742bd6f after lidge-jun#6501 landed. Preserve discovery routing and historical model identities. Co-authored-by: Prince <princepal9120@gmail.com>
|
Partial disposition: #6514 is now merged into dev as The static catalog/metadata replacement and automatic 4.6-to-5.5 migration were not carried, so this PR remains open rather than being closed as fully superseded. #6501 already supplies discovered-family routing; a bounded current-account request succeeded for the 5.5-high wire ID. That observation does not establish the original Windows/multi-account 404 cause. Please narrow any follow-up to the remaining fallback/retirement proposal against current dev, preserve a saved operator effort selection, and supply evidence for the proposed metadata rather than inferring it from the old 4.6 rows. The integrated carry has required scoped CI at https://github.com/lidge-jun/opencodex/actions/runs/37132498856; full release validation remains separate. |
…n retired 4.6 redirects (lidge-jun#6502) - Add static Claude Sonnet 5.5 and Opus 5.5 base models and wire IDs (low/medium/high) to Antigravity catalog, with medium default and 1M context windows matching upstream CCA :fetchAvailableModels evidence. - Map retired Claude 4.6 IDs to 5.5 while preserving operator requested effort (low/medium/high) and clamping max/xhigh/ultra to high without sending redundant thinkingConfig. - Update registry parity, reconciliation, snapshot, and wire routing tests to verify static fallback and effort preservation.

Add one minimal case to cover the fallback to the 5.5 -medium wire ID.
Do not add separate high, low, and default tests for each missing alias. The existing cases already exercise those behaviors for both target families.
