-| D-034 | Temporary long-lived AWS key (waiver) used once in Phase 08 to bootstrap OIDC trust; rotated immediately after | §12.5 forbids long-lived creds; OIDC needs one bootstrapping `aws iam` call before the runner can assume a role | Spike achieves real `terraform plan` against AWS without violating the locked target after bootstrap |
+| D-034 | Temporary long-lived AWS key (waiver) used once in Phase 08 to bootstrap the state backend + IAM user; rotated/deactivated immediately after | §12.5 forbids long-lived creds; the bootstrap needed one `aws iam` call before the spike user + rotated key could take over | Spike achieves real `terraform plan` against AWS without violating the locked target after bootstrap. **CLOSED 2026-07-21: root key `AKIAYOZHMKZ772SINHFX` deactivated by the user in the AWS IAM console (verified — `InvalidClientTokenId`); the spike uses the rotated `acdl-spike-runner` key per D-039.** |
 | D-035 | Milestone version = `v1.1` (feature), ship tag `v1.2.0` | Real platform is a breaking reframing of the demo, but treated as the next incremental milestone per user choice; ship.md: feature milestone → next minor | Tag `v1.2.0` on milestone COMPLETE |
 | D-036 | Spike picks `l1-s3` + `l2-static-asset` | Simplest real AWS resource (no IAM/network deps); smallest real `terraform plan`; proves the IR + adapter end-to-end | Spike scope fixed |
 | D-037 | Demo archived to `demo/` (not deleted) | Preserves the working v1.0 demo as intent reference; new platform layout under `platform/`, `schemas/`, `adapters/`, `terraform/`, `modules-ir/` | No churn on demo code; clean separation |
