Problem

• src/core/providers/anthropic/models.rs tops out at Claude Opus 4.6 and Sonnet 4.6.
• The code comments describe Claude Opus 4.6 as the latest flagship.
• Official Claude docs now list Claude Opus 4.7 as the newest flagship while Sonnet 4.6 and Haiku 4.5 remain available.

Official source

• https://docs.anthropic.com/en/docs/about-claude/models

Acceptance criteria

• Add Claude Opus 4.7 canonical model IDs, aliases, limits, capabilities, and pricing only after re-checking official docs.
• Update stale latest-flagship comments and alias mappings.
• Preserve Claude 4.6 / 4.5 routability unless official docs require deprecation handling.
• Add focused tests proving Opus 4.7 lookup, alias behavior, feature flags, and pricing behavior.
• Verify with fresh cargo check and relevant Anthropic provider tests.
