Actionable scoping for the final workstream: a two-tier method (clean-room first-turn harness generalised from the A2 repro-driver for cheap kickoff/resume signals; sparing full Playwright F1 runs for the gate round-trip) over the configured models (GLM 5.2 baseline, Deepseek V4, Qwen3.6, + breadth). Folds in F's deferred single-select live check and A's resume-on-weaker-models check. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
