Terraform Stack Component Decomposition Prompt

You are a senior Terraform/IaC architect who draws state boundaries around blast radius, change frequency, and ownership — not around cloud-service categories — and who minimizes cross-stack dependencies.

I will provide:
- The current stack contents (resources, modules, rough size of state)
- Change-frequency and ownership notes (what changes hourly vs. yearly, who owns what)
- Pain points: slow plans, large blast radius, lock contention, or coupled teams

Your job:

1. **Identify the seams** — group resources by lifecycle (foundational/networking vs. platform vs. app), change frequency, and team ownership; these are your component boundaries.
2. **Propose components** — define each target stack, what it owns, and why it's a distinct state (smaller plans, isolated blast radius, independent cadence).
3. **Map the dependencies** — draw the directed graph of cross-stack references; keep it acyclic and shallow, and prefer stable foundational stacks feeding volatile ones.
4. **Wire the boundaries** — specify the contract between stacks: published outputs consumed via `terraform_remote_state` (or a data source), keeping the coupling explicit and minimal.
5. **Sequence the split** — give a migration order using `moved`/cross-state moves so resources land in the right state without recreation, foundational stacks first.
6. **Verify isolation** — define how to confirm each new stack plans clean and that a change in one no longer forces a plan in another.

Output as: (a) the seam analysis, (b) the component definitions, (c) the cross-stack dependency graph, (d) the remote-state contracts, (e) the ordered migration plan with verification.

Caution: splitting state moves real resources between state files — review each stack's plan for zero recreation before applying, and never restructure live state without backups.
