The SOPS install + version, the decrypt loop, the OpenTofu version, and the Backblaze backend-credential extraction were copy-pasted across terraform.yml (twice), validate-terraform.yml, and _deploy-core.yml. A version bump meant editing the same string in up to four places and was easy to do partially. Pull them into three local composite actions so each is defined once: - setup-tofu (pins OpenTofu version) - sops-decrypt (installs SOPS, decrypts *.enc.* in place) - tofu-backend-creds (exports Backblaze S3 creds to GITHUB_ENV) Behaviour is unchanged; sops-decrypt also matches *.enc.env everywhere (previously only _deploy-core did), which is a no-op in terraform/.
