[emmy-devop]

Requested by @wagnercosta

Status

Verification completed 2026-09-23. This PR remains a draft pending independent review; do not merge, publish, or run release automation.

What

Add claude-opus-5-5 and gpt-6-sol to the direct DeepNews type used by synchronous and asynchronous SDK methods. Chat and legacy Alert contracts/defaults remain unchanged.

Contract and provenance

The contract is production https://api.asknews.app/openapi.json, re-fetched and verified on 2026-09-23: version 0.32.1, SHA-256 0807aee8af8d37e9b9df9ba510a3606f6d18e469e0da7f98bf53f27d944af7eb; both IDs occur in DeepNewsModel. This is intentionally a narrow model-signature update, not a broad generated schema refresh.

How I tested

• Programmatically verified both models occur in the shared direct DeepNews type used by sync and async methods, and inspected the focused two-file diff plus git diff --check.
• Existing PR CI matrix is green: 10 successful checks across Python 3.8–3.12.
• Local task lint/task test could not run in the isolated checkout because uv, task, pytest, and ruff are absent; no environment tools were installed.

Risk /rollback

Merging triggers the fix: release path: a version bump/tag and PyPI publication of asknews. Revert commit d41b576f92e6089edb1f47147172d808ac7531cf or close this PR to roll back. No workflow or release-automation files changed.
