BLUEPRINT — IaC pre-deploy template assertion

Classification (ADR-0004)

Axis	Value
Scope	platform-feature
Target	repo
Authority	contract
Lifecycle	pre-deploy

Summary

Asserts that an IaC template (Bicep, Terraform, ARM) produces the expected Azure resource graph before deployment. Distinct from MAPROOM — MAPROOM tests the live deployed result; BLUEPRINT tests the template artifact.

Deferral rationale

The assertion mechanism differs per tool (bicep what-if, terraform plan -json, arm what-if). Multi-tool parity means BLUEPRINT must either handle all three or be a thin wrapper over tool-specific adapters. Belongs after Phase 3 reusable workflow rollout when the IaC surface across repos is fully mapped.

Acceptance criteria

• Phase 3 reusable workflow rollout complete
• IaC surface across repos fully mapped
• Adapter strategy decided: unified or per-tool wrappers
• Bicep what-if adapter
• Terraform plan -json adapter
• ARM what-if adapter
• Module docs added under docs/

Target: v0.3.0+
