## Summary

Extend the quality gates and validation scripts to cover Terraform files with
the same rigour as Bicep.

## Prerequisites

Phase 4 complete. Conductor routing validated.

## Items

- [ ] **5.32** Add `terraform fmt -check -recursive` to pre-commit hooks (`lefthook.yml`)
- [ ] **5.33** Add `terraform validate` to `lefthook.yml` for `infra/terraform/**` changes
- [ ] **5.34** Update `validate-artifact-templates.mjs` to recognise Terraform artifact H2 keys
- [ ] **5.35** Update `validate-h2-sync.mjs` for Terraform-specific H2 blocks
- [ ] **5.36** Add `IaC Templates Location` check in `validate-vscode-config.mjs`

## Acceptance Criteria
