Phase 24 — platform-lambda-and-contract-ingestion.
- core/lambda/contract_ingestor.py: AWS Lambda handler invoked via Function
URL (IAM auth). Parses JSON body, validates required fields, writes the
contract to DynamoDB table acdl-contracts (PK consumerRepo, SK
contractId#submittedAt, status submitted, ISO-8601 submittedAt). report_error
action is a stub returning "error_report_prepared"; GitHub issue creation is
wired in Phase 25. Returns 400 on missing fields / unknown action, 500 on
error. Table name + GitHub-token secret ID come from env (set by Terraform).
- core/lambda/__init__.py: empty package marker.
- terraform/platform/main.tf: DynamoDB acdl-contracts (PITR, SSE via CMK),
KMS customer-managed key with alias/acdl-platform, Secrets Manager secret
acdl/github-token, IAM execution role (DynamoDB write + Secrets Manager read +
KMS decrypt + CloudWatch logs), Lambda acdl-contract-ingestor (Python 3.12,
handler contract_ingestor.lambda_handler), Function URL with AWS_IAM auth.
State key platform/terraform.tfstate (distinct from spike/microservice).
- terraform/platform/README.md: documents what it deploys, the state key, how
to apply, and the cross-account invocation model.
- terraform/platform/consumer_invoke_policy.json: ABAC-scoped policy template
applied to consumer deploy roles during onboarding; grants
lambda:InvokeFunctionUrl conditioned on aws:PrincipalTag/acdl:owner ==
consumerRepo.
- tests/test_contract_ingestor.py: 11 tests (moto-backed DynamoDB mock) covering
submit_contract put_item shape, report_error stub, missing-field 400, unknown
action 400, the lambda_handler wrapper with a Function-URL-style event, dict
body, default action, and internal-error 500.
- docs/environments/index.md: new section documenting the cross-account
contract-ingestion grant (one-way consumer→platform, D-051) and that
onboarding now also grants the consumer deploy role InvokeFunctionUrl.
- scripts/run_ci.sh, pipelines/ci.yaml, .gitea/workflows/ci.yml,
.github/workflows/ci.yml: add core/lambda/contract_ingestor.py to the lint
py_compile list. The two workflow YAMLs remain byte-identical.
Verification: scripts/run_ci.sh passes all 3 stages (lint/test/check-only);
python3 -m pytest tests/ -v passes all 213 tests (11 new + 202 existing).
