# create-deploy-role.sh
|
|
#
|
|
# Creates / updates the GitHub Actions OIDC deploy role
|
|
# `githubdeploy-procurement-ingest` in AWS account 011934824531 (seahaven-prod),
|
|
# us-east-1, for the Sea-Haven-Industries/procurement-ingest repo (main branch).
|
|
#
|
|
# Prod-only deploy role (seahaven-prod). The former mgmt twin was deleted in
|
|
# PLAT-67 (2026-08-05); do not recreate a mgmt githubdeploy-procurement-ingest.
|
|
#
|
|
# GATE - DO NOT EXECUTE until BOTH of the following have passed on these
|
|
# exact artifact files:
|
|
# 1. GPT-4.1 cross-family review (IAM policy / trust-policy change) via
|
|
# cross_review.py in the security-review repo.
|
|
# 2. /sh-security-review (deep agentic pass - IaC/IAM is a gated surface).
|
|
#
|
|
# The SmokeInvokeLambda statement is REQUIRED, not optional: deploy.yaml runs
|
|
# scripts/post-deploy-smoke.sh under this role's session (not the assumed
|
|
# cdk-* roles), and the smoke gate fails closed without lambda:InvokeFunction
|
|
# on exactly the two email-processor function ARNs. The mgmt-era equivalent
|
|
# of this policy was applied out-of-band and documented nowhere; these
|
|
# artifacts are the fix for that debt.
|
|
#
|
|
# Resolved facts (verified 2026-07-23, read-only):
|
|
# Account : 011934824531 (seahaven-prod)
|
|
# Region : us-east-1
|
|
# Qualifier : hnb659fds (AWS CDK DEFAULT - matches cdk/cdk.json)
