Cause (Documented platform behavior): Per-policy limit of 2 build workflows; stale workflows count until deleted.
Fix status: documented_behavior
Misleading approaches:
- Treating ServiceQuotaExceededException as throttling and backing off — it will not clear by waiting.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/aws-samples/amazon-bedrock-samples/b5ad367ad897dc8dbb9af0f671b58129d4e19672/responsible_ai/bedrock-automated-reasoning-checks/automated_resoning_policy_refinement.ipynb (official_docs, unknown, documented_behavior): AWS sample notebook output shows this ServiceQuotaExceededException; the sample recovers by 'Clearing failed workflows from queue' (list and delete build workflows) then retrying.

Proposed fix: [Bedrock Automated Reasoning] ServiceQuotaExceededException 'Exceeded maximum number of build workflows allowed: 2' on StartAutomatedReasoningPolicyBuildWorkflow — failed/old workflows o
Recommended action: List build workflows for the policy and delete failed/obsolete ones (list_automated_reasoning_policy_build_workflows + delete) before starting a new one; do not blind-retry.
Option: Delete stale build workflows first [evidence: documented_workaround]
Steps:
1. list_automated_reasoning_policy_build_workflows(policyArn)
2. delete failed/old workflows
3. start the new workflow
Expected: Workflow starts.
