name: Benchmark secret — seed GitHub repo secret into AWS Secrets Manager

# Manually-triggered workflow that copies a GitHub repo secret into AWS
# Secrets Manager at opensre-bench/llm/<secret>. The bench container reads
# its LLM API keys from Secrets Manager at runtime; this workflow is how
# you put them there without touching a developer laptop.
#
# The `secret` dropdown enforces which target is valid — must match one
# of the four IAM-granted secret ARNs in tests/benchmarks/cloudopsbench/infra/iam_oidc.tf
# (anthropic / openai / deepseek / hf_token).
#
# Why a workflow instead of a developer running `aws secretsmanager
# put-secret-value` locally: keeps keys off developer laptops + out of
# shell history, and centralizes rotation — rotate the value in the GH
# repo secret and re-run this workflow to propagate.
#
# Pre-reqs:
#   - tests/benchmarks/cloudopsbench/infra/ Terraform has been applied (the secret resource exists)
#   - Corresponding GitHub repo secret is set:
#     ANTHROPIC_API_KEY / OPENAI_API_KEY / DEEPSEEK_API_KEY / HF_TOKEN
#
# Order of operations:
#   1. terraform-bench.yml (plan) on PR
#   2. terraform apply locally
#   3. this workflow (workflow_dispatch) — pick the secret to seed
#      from the dropdown, repeat once per LLM provider key
