Jon Chery 63f3a2b66c feat(P1): Nova rebrand — docs/decks/prose/schema-$id/release-titles (REQ-155/156/157)

Rebrand ACDL/Agentic Cloud Delivery Platform → Nova across README, docs/,
decks (markdown + mermaid .mmd + HTML), pyproject.toml name/description,
schema $id URLs (acdl.cloudinit.dev→nova.cloudinit.dev), release.yml
title/workflow-name. Nova tagline added to README header + both deck title
slides + docs/vision.md (alongside existing North Star, D-106). S&P theme
untouched (D-107). New docs/NOVA_MIGRATION.md consumer guide. Data values
(env vars, resource names, tag keys, SSM/consumer paths) left for P2-P4.

Nova Modules

Reusable building blocks for cloud infrastructure. Each module is self-documented with a README.md following the template.

How the modules work

There are two kinds of module:

Primitives — a single cloud resource or a small group of related resources (e.g. a VPC with subnets and routing). Each primitive has an interface.json declaring its inputs and outputs, and a README.md in plain language.
Modules — a pattern that references multiple primitives to deploy a complete stack (e.g. an ECS Fargate microservice). Each module has a composition.json declaring its children and wires.

The engine adapter (adapters/terraform/adapter.py) compiles a module instance to infrastructure. Each module's README documents which resources it creates.

Primitives

Module	What it creates	README
`s3`	`aws_s3_bucket` — a single S3 bucket	README
`vpc`	`aws_vpc` + `aws_subnet` + `aws_route_table` + `aws_internet_gateway` — VPC with subnets and routing	README
`ecs-cluster`	`aws_ecs_cluster` — ECS Fargate cluster	README
`ecs-service`	`aws_ecs_task_definition` + `aws_ecs_service` — Fargate service with task definition	README
`iam-role`	`aws_iam_role` — IAM role with assume-role policy	README
`alb`	`aws_lb` + `aws_lb_target_group` + `aws_lb_listener` — Application Load Balancer	README
`ecr`	`aws_ecr_repository` — ECR container image repository	README
`cloudfront`	`aws_cloudfront_distribution` + `aws_cloudfront_origin_access_control` — CloudFront distribution with S3 origin via OAC	README
`waf`	`aws_wafv2_web_acl` — WAFv2 Web ACL (CloudFront-scoped)	README
`rds`	`aws_db_instance` — Relational database (PostgreSQL, MySQL, etc.) with multi-engine support	README
`kms-key`	`aws_kms_key` — Customer-managed KMS key with rotation enabled (per-stack CMK)	README
`uptime`	`aws_ecs_service` — Uptime-kuma monitoring on ECS Fargate with alert channels	README

Modules

Module	What it references	README
`microservice`	6 primitives (vpc, cluster, ecr, iam-role, alb, ecs-service)	README
`static-assets`	3 primitives (s3, cloudfront, waf)	README

Registry

Module versions are tracked in registry.json. Both primitives and modules are registered.

Template

New modules should use README-TEMPLATE.md as their starting point.

Module patterns (roadmap)

The current composition.json mechanism is a thin pattern layer. A future redesign will let a consumer dynamically create a module directly from the contract file (an agentic "composition" flow). That is on the roadmap, not implemented today.
