feat(P4): Nova rebrand — AWS resource migration (REQ-163)

Rename all acdl-* AWS resources → nova-* across terraform (DynamoDB, Secrets Manager, Lambda, SNS, SG, KMS alias, ECS, ECR, IAM user/policy, state bucket, ALB, VPC/subnet names). Lambda default table names → nova-* (D-111). State bucket backend → nova-tfstate (-migrate-state documented). New docs/NOVA_AWS_MIGRATION.md runbook (staged migration + rollback). New scripts/migrate_dynamodb_data.py (scan+copy, dry-run default). acdl-deploy- → nova-deploy- role ARN in deploy workflows. Test fixtures updated; terraform validate + pytest + run_ci.sh PASS. ---ci--- project: acdl phase: 4 milestone: v1.15 status: execute ---/ci---

+
+## Scope (renamed resources)
+
+| AWS resource | Before | After | Strategy |
+|---|---|---|---|
+| KMS alias | `alias/acdl-platform` | `alias/nova-platform` | cheap rename |
+| SNS topic | `acdl-sod-halt` | `nova-sod-halt` | recreate |
+| Security group | `acdl-ecs-sg` | `nova-ecs-sg` | recreate |
+| Lambda (role/policy/function) | `acdl-contract-ingestor` | `nova-contract-ingestor` | recreate |
+| DynamoDB contracts | `acdl-contracts` | `nova-contracts` | scan + copy |
+| DynamoDB change-requests | `acdl-change-requests` | `nova-change-requests` | scan + copy |
+| Secrets Manager secret | `acdl/github-token` | `nova/github-token` | recreate + re-store |
+| ECR repo | `acdl-microservice` | `nova-microservice` | re-push |
+| ECS cluster/service/task/role | `acdl-microservice` | `nova-microservice` | recreate |
+| IAM user + policy | `acdl-spike-runner` (+ `-policy`) | `nova-spike-runner` (+ `-policy`) | re-bootstrap |
+| IAM act-runner role | `acdl-act-runner-role` | `nova-act-runner-role` | re-bootstrap |
+| IAM deploy role | `acdl-deploy-<repo>` | `nova-deploy-<repo>` | re-bootstrap |
+| S3 state bucket | `acdl-tfstate-581513795199-us-east-1` | `nova-tfstate-581513795199-us-east-1` | `-migrate-state` |
+| DynamoDB outbox | `acdl-outbox` | `nova-outbox` | scan + copy |
+| Platform VPC/subnet/IGW/RT | `acdl-shared*` | `nova-shared*` | recreate (brief downtime) |
+| CI VPC/subnet/SG/cluster | `acdl-ci-*` | `nova-ci-*` | recreate (CI-only) |
+| ALB name prefix | `acdl-alb` | `nova-alb` | recreate (brief downtime, LAST) |
+
+## Migration ordering (binding)
+
+Order: **KMS alias → SNS/SG → Lambda → DynamoDB → ECR → IAM → state bucket → ALB**.
+Each step is independently rollback-able. The ALB is last because it
+requires the briefest downtime window.
+
+---
+
+## Pre-flight
+
+1. **Announce the maintenance window** (consumers are notified via the
+   P1 migration guide `docs/NOVA_MIGRATION.md`).
+2. **Back up state** for every stack (see §State bucket — back up the
+   state JSON *before* `-migrate-state`).
+3. Confirm `NOVA_LIFECYCLE_MODE=plan` (default) so CI does not mutate
+   AWS during the window.
+4. Confirm the new `nova-*` destination tables/repos will be created by
+   the same Terraform apply (no manual pre-creation needed).
+
+## Step 1 — KMS alias (`alias/acdl-platform` → `alias/nova-platform`)
+
+- **Command (in `terraform/platform/`):**
+  ```bash
+  terraform init -upgrade
+  terraform apply -replace=aws_kms_alias.nova_platform
+  ```
+  (Terraform destroys the old alias + creates the new one — aliases are
+  cheap; the underlying key ID is unchanged.)
+- **Verify:** `aws kms list-aliases --query 'Aliases[?AliasName==`alias/nova-platform`]'` returns the new alias; `alias/acdl-platform` is gone.
+- **Rollback:** `terraform apply -replace=aws_kms_alias.nova_platform` against the prior revision (re-creates `alias/acdl-platform`). Resources encrypted by the key are unaffected (key ID unchanged).
+
+## Step 2 — SNS topic + Security group (recreate)
+
+- **Command:** `terraform apply` in `terraform/platform/`.
+  - SNS `acdl-sod-halt` → `nova-sod-halt` (the topic ARN changes; update `NOVA_SOD_HALT_TOPIC_ARN` wherever it is set).
+  - SG `acdl-ecs-sg` → `nova-ecs-sg` (the security group is re-attached to running ECS tasks; brief task restart).
+- **Verify:** `aws sns list-topics` shows `nova-sod-halt`; `aws ec2 describe-security-groups` shows `nova-ecs-sg`.
+- **Rollback:** `terraform apply` the prior revision re-creates the `acdl-*` names. The SNS topic has no message backlog (halt artifacts are fire-and-forget); the SG drift resolves on next task deploy.
+
+## Step 3 — Lambda (recreate)
+
+- **Command:** `terraform apply` in `terraform/platform/`.
+  - Lambda function `acdl-contract-ingestor` → `nova-contract-ingestor`.
+  - Execution role `acdl-contract-ingestor-role` → `nova-contract-ingestor-role`.
+  - Inline policy `acdl-contract-ingestor-policy` → `nova-contract-ingestor-policy`.
+  - The Lambda env vars (`CONTRACTS_TABLE`, `GITHUB_TOKEN_SECRET_ID`) now resolve to `nova-*` defaults.
+- **Verify:** `aws lambda list-functions` shows `nova-contract-ingestor`; the Function URL returns 200 on a SigV4-signed invoke. The `consumer_invoke_policy.json` rendered output (Terraform `consumer_invoke_policy_rendered`) now references `function:nova-contract-ingestor` — re-distribute to consumer deploy roles.
+- **Rollback:** `terraform apply` the prior revision re-creates `acdl-contract-ingestor`. Consumer deploy roles must point back at the old Function ARN (re-distribute the prior `consumer_invoke_policy.json`).
+
+## Step 4 — DynamoDB (scan + copy)
+
+DynamoDB table names are immutable post-creation, so the migration is a
+**scan + copy** (not a rename). The new `nova-*` tables are created by
+the same Terraform apply (Step 3). The data-migration script copies
+every item and verifies row counts.
+
+- **Command (from repo root):**
+  ```bash
+  # Dry-run first (no writes):
+  python3 scripts/migrate_dynamodb_data.py
+  # Execute the copy:
+  python3 scripts/migrate_dynamodb_data.py --apply
+  # A single table:
+  python3 scripts/migrate_dynamodb_data.py --table contracts --apply
+  ```
+  The script scans `acdl-contracts` → copies to `nova-contracts`, and
+  `acdl-change-requests` → `nova-change-requests`, then verifies the
+  destination row count == source row count (re-scan, not
+  `DescribeTable.ItemCount` which lags ~6h).
+- **Verify:**
+  ```bash
+  # Row counts must match (printed by the script). Manual cross-check:
+  aws dynamodb scan --table-name nova-contracts --select COUNT
+  aws dynamodb scan --table-name acdl-contracts --select COUNT
+  ```
+  Then **point consumers at the new tables** (the Lambda already reads
+  `nova-*` defaults; any direct DynamoDB consumers update their env).
+- **Keep the old tables** (`acdl-contracts`, `acdl-change-requests`)
+  until consumers are verified reading from `nova-*`. **Deletion is a
+  manual post-verification step:**
+  ```bash
+  aws dynamodb delete-table --table-name acdl-contracts
+  aws dynamodb delete-table --table-name acdl-change-requests
+  ```
+  Only delete after a full soak period confirms `nova-*` reads succeed.
+- **Rollback:** Re-point consumers at `acdl-*` (the old tables are
+  retained). The copy is additive (no data loss). To roll back a partial
+  copy, re-run `--apply` (idempotent — `PutItem` overwrites).
+
+### Outbox table (`acdl-outbox` → `nova-outbox`)
+
+The evidence outbox table follows the same scan+copy pattern (it is
+created by `terraform/bootstrap/create_state_backend.py`).
+- **Command:** `python3 scripts/migrate_dynamodb_data.py --source acdl-outbox --dest nova-outbox --apply`
+- The `core/outbox_writer.py` default + `core/regression_verify.py`
+  CAP-015 probe now reference `nova-outbox` (P4 updated both). The
+  regression gate's live-AWS CAP-015 will return `Verified` once the
+  `nova-outbox` table exists live; until then it is `Decayed` (the gate
+  is re-run at milestone complete after the live migration).
+
+## Step 5 — ECR (re-push)
+
+- **Command:** `terraform apply` in `terraform/microservice/` creates
+  the new `nova-microservice` ECR repo. Re-push the image:
+  ```bash
+  python3 scripts/push_consumer_image.py   # creates nova-microservice + prints docker tag/push
+  ```
+  (The script's `ECR_REPO_NAME` is now `nova-microservice`.)
+- **Verify:** `aws ecr describe-repositories` shows `nova-microservice`; `docker pull <acct>.dkr.ecr.us-east-1.amazonaws.com/nova-microservice:latest` succeeds.
+- **Rollback:** The old `acdl-microservice` repo is retained until the
+  soak passes. Re-push to it if a rollback is needed. Delete it manually:
+  `aws ecr delete-repository --repository-name acdl-microservice --force`.
+
+## Step 6 — IAM (re-bootstrap)
+
+- **Command:**
+  ```bash
+  export NOVA_BOOTSTRAP_AWS_ACCESS_KEY_ID="<root key>"
+  export NOVA_BOOTSTRAP_AWS_SECRET_ACCESS_KEY="<root secret>"
+  python3 terraform/bootstrap/create_state_backend.py        # creates nova-outbox (idempotent)
+  python3 terraform/bootstrap/create_iam_user.py             # creates nova-spike-runner
+  python3 terraform/bootstrap/apply_iam_baseline.py          # creates nova-spike-runner-policy + nova-act-runner-role
+  bash scripts/rotate_spike_key.sh                          # rotates the nova-spike-runner key
+  ```
+  The deploy role `acdl-deploy-<repo>` → `nova-deploy-<repo>` is
+  created by the bootstrap (the deploy workflow
+  `.gitea/.github/workflows/deploy.yml` now references
+  `role/nova-deploy-{1}`).
+- **Verify:** `aws iam get-user --user-name nova-spike-runner`;
+  `aws iam list-attached-user-policies --user-name nova-spike-runner`
+  shows `nova-spike-runner-policy`;
+  `aws iam get-role --role-name nova-act-runner-role`.
+- **Rollback:** Re-run the prior bootstrap scripts (they create
+  `acdl-spike-runner` + `acdl-act-runner-role`). The deploy workflow's
+  `role-to-assume` must be reverted to `acdl-deploy-` (prior revision).
+
+## Step 7 — State bucket (`acdl-tfstate-*` → `nova-tfstate-*`, `-migrate-state`)
+
+The S3 state backend is renamed. Terraform's `-migrate-state` copies the
+state objects to the new bucket. **Back up the state JSON first.**
+
+- **Back up state (per stack):**
+  ```bash
+  for stack in platform microservice ci-vpc; do
+    aws s3 cp s3://acdl-tfstate-581513795199-us-east-1/$stack/terraform.tfstate \
+      ./backup-$stack.tfstate
+  done
+  ```
+- **Command (per stack):** the backend config in each
+  `terraform/*/terraform.tf` now points at `nova-tfstate-...`.
+  ```bash
+  cd terraform/platform
+  terraform init -migrate-state        # copies state acdl-tfstate → nova-tfstate
+  cd ../microservice
+  terraform init -migrate-state
+  cd ../ci-vpc
+  terraform init -migrate-state
+  ```
+- **Verify:** `aws s3 ls s3://nova-tfstate-581513795199-us-east-1/`
+  shows the state keys; `terraform state list` in each dir lists the
+  expected resources.
+- **Rollback:** Point the backend back at `acdl-tfstate-*` and re-run
+  `terraform init -migrate-state` (restores from the backup bucket). The
+  old `acdl-tfstate-*` bucket is retained until the soak passes. Delete
+  it manually:
+  `aws s3 rb s3://acdl-tfstate-581513795199-us-east-1 --force`.
+
+## Step 8 — ALB (recreate, brief downtime, LAST)
+
+The ALB is last because its recreation requires the briefest downtime
+window (the ECS service is re-attached to the new target group).
+
+- **Command:** `terraform apply` in `terraform/microservice/`. The ALB
+  `acdl-microservice` / `acdl-alb` → `nova-microservice` / `nova-alb`.
+- **Verify:** `aws elbv2 describe-load-balancers` shows the new ALB;
+  `curl http://<new-alb-dns>/` returns 200.
+- **Rollback:** `terraform apply` the prior revision re-creates the
+  `acdl-*` ALB (brief downtime again). The old ALB DNS is retained until
+  consumers are re-pointed.
+
+---
+
+## Post-migration
+
+1. **Soak:** run consumers against `nova-*` for a full verification
+   window (deploy a test contract end-to-end).
+2. **Delete old resources** (manual, only after soak):
+   - DynamoDB: `acdl-contracts`, `acdl-change-requests`, `acdl-outbox`
+   - ECR: `acdl-microservice`
+   - IAM: `acdl-spike-runner` (+ policy), `acdl-act-runner-role`,
+     `acdl-deploy-<repo>`
+   - S3: `acdl-tfstate-581513795199-us-east-1`
+   - SNS: `acdl-sod-halt`
+   - SG: `acdl-ecs-sg`
+   - Secrets Manager: `acdl/github-token`
+   - KMS alias: `alias/acdl-platform`
+   - ALB: `acdl-alb` / `acdl-microservice`
+3. **Regression gate:** re-run `bash scripts/run_regression.sh`. The
+   live-AWS CAP-013..016 probes should return `Verified` (the `nova-*`
+   tables + state bucket exist). CAP-015 (outbox) flips from `Decayed`
+   → `Verified` once `nova-outbox` is live.
+
+## What P5 owns (not P4)
+
+- **Remove dual-read fallback:** `core/env.py` `get_env()` drops the
+  `ACDL_*` fallback; shell scripts drop `:-$ACDL_X`. P4 keeps the
+  dual-read (deployments don't break mid-window).
+- **`nova_tagging.py` hard-fail on `acdl:*`:** P3 set hard mode (no
+  `acdl:*`-only tags); P5 tightens to fail on any `acdl:*` presence. P4
+  leaves P3's behavior.
+- **Delete `ACDL_*` Gitea secrets:** the `NOVA_*` aliases created in P2
+  are now the only source.
+- **Finalize `docs/NOVA_MIGRATION.md`:** mark the migration complete
+  (cutoff passed).
+- **Milestone ship:** tag `v1.15.4`, merge to `main`, Gitea release.
+
+## Files touched in P4
+
+- `terraform/platform/main.tf`, `terraform/microservice/main.tf`,
+  `terraform/ci-vpc/main.tf` — resource renames + backend bucket.

+"""Migrate DynamoDB table data from acdl-* → nova-* (REQ-163, P4).
+
+The Nova rebrand (v1.15) renames the platform DynamoDB tables:
+  - ``acdl-contracts``       → ``nova-contracts``
+  - ``acdl-change-requests`` → ``nova-change-requests``
+
+DynamoDB table names are immutable post-creation, so the migration is a
+**scan + copy**: every item in the old table is written to the new table
+(preserving the full item shape — PK, SK, and all attributes). Row counts
+are verified to match post-copy. The old tables are **kept** until the
+operator verifies the copy; deletion is a manual post-verification step
+documented in ``docs/NOVA_AWS_MIGRATION.md`` (runbook).
+
+Design:
+  - **Dry-run by default.** Prints the planned copy operations + counts
+    without touching AWS. Pass ``--apply`` to execute the copy.
+  - **Idempotent.** Re-running against an already-migrated item is a
+    no-op (``PutItem`` overwrites in place; the copy is re-run but the
+    row counts still match). The script does NOT delete the old tables
+    (deletion is a manual runbook step).
+  - **Item-mapping logic is pure + unit-tested** (see
+    ``tests/test_migrate_dynamodb_data.py``); the AWS I/O is thin boto3
+    glue around ``map_item()`` + ``scan_all()``.
+  - **boto3 lazy import.** The module is importable + unit-testable
+    without AWS credentials (the client is constructed inside ``run()``).
+
+Usage:
+  python3 scripts/migrate_dynamodb_data.py                 # dry-run (default)
+  python3 scripts/migrate_dynamodb_data.py --apply         # execute the copy
+  python3 scripts/migrate_dynamodb_data.py --region us-east-1 --apply
+  python3 scripts/migrate_dynamodb_data.py --table contracts --apply
+  python3 scripts/migrate_dynamodb_data.py --source acdl-contracts --dest nova-contracts --apply
+
+Pre-requisites (live AWS, documented in the runbook):
+  - The nova-* destination tables must already exist (created via
+    ``terraform/platform/main.tf``).
+  - AWS credentials in env with scan+PutItem on both old + new tables.
