Bump the default Opus route/model from claude-opus-4-7 to claude-opus-4-8
across provider presets (claude, claudeDesktop, hermes, openclaw, opencode,
universal), i18n locales (zh/en/ja/zh-TW), pricing seed data, and the
user-manual docs.
- Add claude-opus-4-8 pricing row ($5/$25/$0.50/$6.25); keep the 4-7 row
for historical usage stats (seeded via INSERT OR IGNORE).
- Claude Desktop proxy: accept bidirectional opus 4-7 <-> 4-8 route alias
during rollout so previously saved routes keep resolving.
- thinking_optimizer: route opus-4-8 through adaptive thinking and normalize
dotted model ids (also fixes dotted 4-6/4-7 falling back to legacy).
- usage_stats: normalize Bedrock/Vertex/aggregator opus-4-8 ids to base
pricing.
Also merge role:"system" messages into the Gemini systemInstruction in the
Anthropic->Gemini transform.
Copilot upstream returns model_not_supported when the client sends
dash-form Claude IDs (claude-sonnet-4-6, claude-sonnet-4-6[1m]) while
/models only accepts dot form (claude-sonnet-4.6, -1m suffix).
- Add copilot_model_map: syntax normalize (dash->dot, [1m]->-1m) plus
live /models exact match and family-version fallback, reusing the
existing 5 min auth cache. Returns None when the whole family is
absent so upstream surfaces an explicit error instead of silently
switching families.
- Wire into forwarder Copilot hook; runs before anthropic_to_openai
conversion.
- Default Opus slot in the Copilot preset maps to Sonnet 4.6: Pro
dropped all Opus on 2026-04-20 and Pro+ bills Opus 4.7 at 7.5x.
Users who want real Opus can switch manually in the UI.
