This is the known single-account-wide CDK cfn-exec residual already documented in infra/lib/config.ts:31-34 and the github-deploy-roles.ts construct comment, accepted at the T4 GPT-4.1 IAM cross-review and the v5 plan-review. WHO can assume each env's infra role is exact-subject scoped (StringEquals on the dev ref / prod environment); the residual is the shared account-wide cfn-exec-role that every env's infra role can reach. The tracked fix is per-env CDK bootstrap qualifiers so each env's infra role assumes its own env-scoped cfn-exec-role. Suppressed for THIS change's gate because it is out-of-diff and unchanged; surfaced to Adam for scheduling the per-env-bootstrap remediation.",

      "severity": "low",
      "status": "confirmed",
      "suppression_justification": "ACCEPTED LOW residual, metadata-only. fetch-config.sh materializes the .env via `batch-get-secret-value --filters Key=name,Values=open-swe-<env>/`. With a name FILTER, both BatchGetSecretValue (a collection call) and ListSecrets are authorized by AWS against `*`, NOT a per-secret ARN — a prefix-scoped ARN AccessDenies the call (confirmed empirically on i-0af4e03e8bf70e6c3). So the two `*` grants are operation-level, not value-level. Secret VALUES remain strictly gated by the PREFIX-scoped GetSecretValue/DescribeSecret on secret:open-swe-<env>/* (GetSecretValue is checked per-secret even within the batch), so cross-env VALUE isolation is preserved; only NAMES/tags/descriptions are enumerable, within Sea Haven's own single-tenant account 328440206208. Confirmed by GPT-4.1 IAM cross-review (BLOCK: none) and the iac-iam detector (one low residual, no critical/high). Future hardening to eliminate BOTH `*` grants: switch fetch-config.sh to an explicit `--secret-id-list` (no filter), which lets BatchGetSecretValue be prefix-scoped and needs no ListSecrets.",
