0.1.8 RC1: Run the fixed K2.7 Responses regression batch #288

Parent

#257 (part of #248)

Outcome

Run and publish the immutable fixed maintained-Provider regression batch for Ollama Cloud K2.7 Code over Responses on the exact RC candidate.

Cover the shipped Beta2 generic compatibility core, Beta3 client tool-discovery/Code Mode workflows, and Beta4 Collaboration V2 lifecycle.

Acceptance criteria

• The core Responses profile records 10/10 clean fixed cases without selective replacement.
• Code Mode, explicit-hint client tool_search, and Collaboration V2 each record the required clean fixed sub-batch.
• Beta1 K2.7 catalog and context-scope regressions remain green.
• Exact Provider/model identity remains unchanged and no cross-Provider tool execution occurs.
• Failed, degraded, superseded, and external-availability attempts remain visible and cannot be overwritten.
• Evidence is bounded, sanitized, candidate-bound, and cleaned on every exit path.
• The result is maintained-Provider release evidence, not a runtime model allowlist.
