Nightly backup jobs fail on resources that have left the management account.
The CloudFront WebACL is already gone while CloudFormation still owns it, so
the deletion policy has to be Retain before a later change can remove it.
* Parameterize baseline constructs for multi-account reuse
DetectiveControls, FlowLogs, and GovernanceToggles were forked into
seahaven-external-dev-baseline with only physical-name and VPC-sourcing
differences. Prefix/name props let one implementation serve both
accounts; synthesized templates are unchanged (verified: empty cdk diff
against all deployed stacks).
* Absorb external-dev member baseline stack
Moves seahaven-external-dev-baseline's stack in as MemberBaselineStack,
construct ids and physical names byte-identical to the deployed stack
(logical IDs are path-derived; empty cdk diff verified via change set
against 396287094661). Retires the forked repo so member-account
baselines share one drift surface and one dependency pin.
* Rename package to seahaven-org-baseline
Prepares the repo rename: the app now spans the management account and
org member accounts, so 'account-baseline' undersells the scope. README
documents the two-account deploy topology and logical-ID constraints.
* Commit extdev flow-log VPC ids in code, not -c context
Security review SH-ORG-004 (confirmed high): with the ids sourced from
ephemeral cdk context, any context-less deploy silently removes every
flow log in the isolated account. A committed list makes the attachment
set reviewable and immune to a forgotten -c flag. Empty list matches
the deployed stack (zero diff).
* Split CD into per-account deploy jobs
The app now spans two AWS accounts; cdk deploy --all under one role
fails on the other account's stacks (security review IAC-01). Each job
passes explicit stack selectors and its own account's OIDC role via the
new cd-cdk stacks input.
