# terraform-e2e — Handoff (Step 4 complete)

Updated: 2026-02-26T00:00:00Z | IaC: Terraform | Branch: tf-dev

## Completed Steps

- [x] Step 1: Requirements → `agent-output/terraform-e2e/01-requirements.md`
- [x] Step 2: Architecture → `agent-output/terraform-e2e/02-architecture-assessment.md`
- [x] Step 3: Design → `agent-output/terraform-e2e/03-des-*.md`, `03-des-*.py/.png`
- [x] Step 4: IaC Plan → `agent-output/terraform-e2e/04-implementation-plan.md`
- [ ] Step 5: IaC Code
- [ ] Step 6: Deploy
- [ ] Step 7: As-Built

## Key Decisions

- Region: swedencentral
- Compliance: Azure Policy (28 policies: 10 Deny, 4 Audit, 2+ Modify/DINE)
- Budget: ~$25–60/mo (dev)
- IaC tool: Terraform
- Architecture pattern: N-tier ecommerce (App Service frontend + App Service backend + SQL + Key Vault)
- Deployment: 3-phase via `var.deployment_phase` (Foundation → Security/Data → Compute/Frontend)
- AVM coverage: 6/6 modules (SWA replaced with App Service — not available in swedencentral)
- User feedback applied: SWA → App Service (frontend), lifecycle prevent_destroy dismissed

## Open Challenger Findings (must_fix only)

None — 0 must_fix across all review passes.

## Context for Next Step

Step 5 (Terraform CodeGen) should read `04-implementation-plan.md` for the 13-task, 3-phase plan and `04-governance-constraints.json` for policy compliance mappings. **Key change from original plan**: SWA replaced with a frontend App Service sharing the B1 plan (SWA not available in swedencentral). lifecycle { prevent_destroy } on Key Vault/SQL dismissed by user. Remaining should-fix: diagnostic settings and health check endpoint.
