Feed notes

• Community-maintained seed dataset, compiled 2026-07-25 from the provider's deprecations page. Verify against the source before acting; this file demonstrates the format. Anthropic policy floor: >=60 days notice for publicly released models. Weights of public models are preserved per the Nov 2025 commitments - preservation is not availability.

Eval

• Result: pass (exit code 0).

Verified isolated migration from claude-3-5-sonnet-20241022 to claude-sonnet-4-6.

Checklist

• Review the diff
• Run evals
• Verify params/behavior

Warning: checks may be skipped because PRs created with GITHUB_TOKEN do not trigger pull_request workflows. Use a fine-grained PAT or GitHub App token when checks must run.
