* Add seahaven-prod member baseline (Phase 5) Account 011934824531 is the target for all new production stacks; the management account is frozen for new workloads. First proven exercise of the automatic enrollment sweep (Enabled in 124s, no manual create-members) and of AutoEnableStandards=NONE (no pre-enabled standards, so CFN owns FSBP + CIS v3.0 cleanly). Default VPC deleted; budget starts at $100 and resizes as tenants land. * Apply Phase-5 review findings Fleet gap closed: EBS encryption-by-default + IAM password policy were management-account-only (the runbook's unscoped 'applied' claim hid it); now applied and verified in all three member accounts, runbook scoped per account. README stack inventory corrected (eleven stacks, org-governance rows restored). Sweep comments reconciled: the automatic enrollment sweep is proven (seahaven-prod, ~2min).

* - No local CloudTrail — the management-account org trail (seahaven-org-trail)
|
|
* already captures every member account's events centrally.
|
|
* - No CIS Section-4 metric-filter alarms — the Security Hub CIS standard
|
|
* evaluates those controls against Config without a local trail log group.

|
* - No WAF, SES monitoring, Bedrock logging, DynamoDB CMK, or AWS Backup —
|
|
* all prod-only concerns.
|
|
*
|
|
* Contains: AWS Config, Security Hub standards (FSBP + CIS v3.0), IAM Access
|
|
* Analyzer, Inspector2 (post-deploy CLI, see README), VPC flow logs, and a
|
|
* monthly cost Budget — plus the GuardDuty detector + Security Hub hub only
|
|
* when the account predates org delegation (orgManagedDetection false); newer
|
|
* accounts get those from the delegated admin.
