Pull request overview
Switches the 13 analysis/article-generating agentic news workflows from claude-sonnet-4.6 to claude-opus-4.8 while keeping news-translate on Sonnet for high-volume translation throughput. All 14 .lock.yml siblings are recompiled, the pass-2 budget contract test is updated, and the model split is reflected across user-facing and future-state documentation.
Changes:
- Set
model: claude-opus-4.8in 13news-*.mdsources and propagate to the 14 recompiled lock files (translate lock stays Sonnet). - Update
tests/news-workflow-pass2-budget-contract.test.tsto assert the Opus model on content workflows and Sonnet onnews-translate. - Refresh
README.md,Article-Generation.md,WORKFLOWS.md(v7.6),ARCHITECTURE.md(v2.6),.github/copilot-instructions.md,.github/workflows/README.md,FUTURE_*.md, and skill docs to document the split (Opus 4.7 → 4.8).
