[aw-fix] PR Code Quality Reviewer: fresh failure today after #42095 closure — model tier/tooling error recurrence

[github-actions]

Problem

The PR Code Quality Reviewer workflow failed again on 2026-07-03 (run §28661680929), following the closure of #42095. The Workflow Health Manager noted this as a fresh failure requiring new tracking.

Previous History

• [aw-failures] PR Code Quality Reviewer red — Copilot general-purpose subagent requests tier-unsupported model → SDK 400 `model [Content truncated due to length] #42095 (closed) — tracked tier-unsupported model error
• Fresh failure today §28661680929 — suggests root cause was not fully resolved or has regressed

Context from WHM

From workflow-health-latest.md (Jul 3):

PR Code Quality Reviewer: Fresh failure today run §28639714841, #42095 closed — may need new issue.

Investigation Needed

1. Confirm the failure mode in §28661680929 — is it still tier-unsupported model or a new error?
2. If same root cause: the fix applied to close [aw-failures] PR Code Quality Reviewer red — Copilot general-purpose subagent requests tier-unsupported model → SDK 400 `model [Content truncated due to length] #42095 did not hold — identify regression
3. If new error: document the new failure mode and fix

Likely Root Causes

• Model tier mismatch: Workflow configured to use a model tier not available in the runner context
• Tool availability: Required code analysis tools blocked by sandbox seccomp
• Engine routing: copilot engine directing to an unsupported model variant

Recommended Fix

• Verify model configuration in the workflow matches available tiers
• If model was changed as part of [aw-failures] PR Code Quality Reviewer red — Copilot general-purpose subagent requests tier-unsupported model → SDK 400 `model [Content truncated due to length] #42095 fix, revert or try alternative model
• Add a validation step in the workflow to gracefully handle missing tool access
