[C5 HL-034] Define reproducible service infrastructure and delivery automation #44

Outcome

Provision only the services proven necessary by platform consumers.

Placement and activation

• Circle: C5 — Reusable and operated product platform
• System responsibilities: Platform
• Capability coverage: 06 Infrastructure & Runtime; 09 Developer Platform & Tooling
• Planning status: Conditional; activate only when the requirement below is met.
• Activation: A service runtime beyond static distribution exists.
• Parent epic: [EPIC C5] Reusable and operated product platform #8; master roadmap: [MASTER EPIC] Hole-loop: concentric evolution within Persona / Visual Form Canon #2.

Dependencies

Required prerequisites:

• A selected service runtime, named owner, dependency/resource inventory, deployment artifact, and runtime contract from HL-004 #13.
• Relevant delivery, least-privilege release, exact-version verification, and recovery practices from HL-010 #20 or HL-016 #26; these apply to the selected runtime rather than requiring completion of a different edition.

Conditional dependencies:

• HL-031 #41 applies when the deployed service exposes a consumer API or integration.
• HL-032 #42 applies when the service persists managed or participant data.
• HL-033 #43 applies when the service requires account, tenant, or enterprise administration.

A stateless worker may be provisioned without persistence or accounts. Static browser delivery remains covered by HL-016 #26; local libraries and installations that need no service do not activate this issue.

Acceptance evidence

• Record cloud/edge/serverless/container resource definitions, DNS/networking, environments, configuration, secrets, feature-flag ownership, and deployment dependencies for selected services.
• Choose Terraform/Pulumi or other IaC by actual runtime needs; define local, preview, staging, production separation where applicable, with least-privilege delivery identities.
• Build versioned images/artifacts if needed, security/dependency checks, promotion/rollback, migrations, release automation, budgets, and capacity assumptions.
• Verify recreation in a non-production environment and recovery from a failed deploy; no undocumented manual production configuration remains.
• Extract infra only with an independent lifecycle/permission/deployment boundary and an owned composition/migration contract.

Completion and scope

Attach the actual artifact or commit, relevant verification, limitations, and an artist decision where a composition changes. This issue plans authorized work; creation does not claim implementation or deployment. Preserve independent work/source identities and private source boundaries. Repository creation requires the extraction evidence in HL-004 #13 and HL-045 #14.
