[Terraform] 'Incomplete lock file information for providers' / provider install fails on another OS/arch — .terraform.lock.hcl only has checksums for the platform where init ran

Cause (Documented platform behavior): Without the registry's signed checksum list, Terraform records checksums only for the current platform; other platforms' packages cannot be verified against the lock file. Fix status: documented_behavior Misleading approaches: - Deleting .terraform.lock.hcl in CI removes the integrity pin instead of adding the missing platform hashes Unknowns: - Exact CI-side error wording on the failing platform was not captured from source Other error fragments: - The current .terraform.lock.hcl file only includes checksums for %s, so Terraform running on another platform will fail to install these providers. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/hashicorp/terraform/main/internal/command/init.go (official_docs, unknown, documented_behavior): init prints 'Incomplete lock file information for providers': due to customized installation methods checksums were calculated locally, the lock file only includes checksums for the current platform so other platforms will fail, and suggests 'terraform providers lock -platform=linux_amd64'. - https://raw.githubusercontent.com/hashicorp/web-unified-docs/main/content/terraform/v1.13.x/docs/language/files/dependency-lock.mdx (official_docs, unknown, official_recommended_action): When installing via a mirror, Terraform cannot verify checksums for other platforms and the config will not be usable elsewhere; pre-populate multi-platform checksums with terraform providers lock.
