---ci--- project: acdl phase: 10 milestone: v1.1 status: plan-as-execute persona: platform-engineer task: [T-10.1, T-10.2, T-10.3, T-10.6] requirements.covered: [REQ-25] ---/ci--- Wave 1: L2 thin-composition + registry extension + adapter L2 handling. - T-10.1: modules-ir/l2/l2-static-asset/composition.json (kind=l2, depth=1, one child l1-s3@1.0.0, wires passthrough). - T-10.2: modules-ir/registry.json extended with l2-static-asset@1.0.0. - T-10.3: modules-ir/l2/l2-static-asset/README.md (D-P10-1 doc). - T-10.6: adapters/terraform/adapter.py - backend key now derived from the stack name (spike/<stack_name>/terraform.tfstate). The resources array handling is unchanged; a resolved L2 IR instance has the L1 resource as resources[0], so the existing TYPE_MAP + resource emission handle it (the adapter is shape-driven, not kind-driven).
l2-static-asset — thin-composition (S3 static asset)
The v1.1 spike's L2. A thin-composition that references l1-s3 only
(depth 1). The contract's inputs (bucket_name, region) map 1:1
through the wires to the L1's inputs.
Composition (the IR-typed thin-composition tree)
See composition.json: kind=l2, depth=1, one child l1-s3@1.0.0,
wires {bucket_name → s3.inputs.bucket_name, region → s3.inputs.region}
(passthrough).
IR → Terraform mapping (D-P10-1)
The Terraform adapter consumes the resolved IR instance (which has
kind=l2 + the L1 resource s3 in its resources array). For a
depth-1 thin-composition, the L2 root module IS the L1's resource —
no separate module "l1_s3" { source = "..." } block. The existing
adapter TYPE_MAP + resource emission handle both l1 and l2 instances
(the resources array is the same shape). The relationships array is
ignored at the Terraform level for the spike (composition ordering is
implicit in the single resource).
v1.2 may emit a real module "l1_s3" { source = "..." } block when L1s
become published Terraform modules rather than inline resources.
Versioning (W3.D)
1.0.0 — interface MAJOR, behavior MINOR, lifecycle PATCH. MAJOR bumps
require a new registry entry (immutable publication); old entries enter
a 12-month deprecation window.
