Read #2464 Pick up a Lab task

Most members concern auxiliary-task model selection (compression, title generation, web tools) falling back to hardcoded or paid OpenRouter defaults rather than honoring user-configured fallback_providers, free-only settings, or session-level model switches. Proposed changes include removing hardcoded defaults, preserving the :free suffix, and propagating model switches.

How this cluster was grouped

Link evidence (partly structural links): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
Members outside that structural core may belong to a different underlying problem.
Pairwise link density 0.09: the share of item pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. 1.00 means every pair is linked.
