Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(guardrails): tolerate unmodeled Responses input items in Azure prompt extraction

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(guardrails): pick Azure prompt source by call type so a messages stub cannot hide Responses input

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(guardrails): tighten Azure Content Safety endpoint test types

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(guardrails): suppress Azure cast lint violations with cast-ok reasons

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(guardrails): audit Azure content safety across endpoints

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(guardrails): isolate worker-kill audit rig and cover during_call on chat

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* style(guardrails): shorten Azure cast-ok reasons to fit the line limit

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(guardrails): inline spend row count in the concurrency audit cell

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(guardrails): assert caller-observed outcomes in Azure call type unit tests

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(guardrails): reuse the existing text moderation response helper

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(guardrails): assert no duplicate rows instead of exact row count after worker kill

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(guardrails): poll worker-kill spend rows to settle before the duplicate check

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(guardrails): keep Azure Text Moderation on messages only so this PR stays Prompt Shield scoped
