phase: 1
milestone: v1.0

requirements:
  covered: [REQ-01, REQ-09]

---/ci---

Squash merge of phase/01-repo-scaffolding into milestone/v1.0-initial.
Phase 01 ships the three-repo scaffold (acdl, acdl-contracts, acdl-evidence),
the placeholder index.html on acdl-evidence (D-012/D-016 raw-URL substitute
for unsupported Gitea Pages), the qa + prod branches on acdl-contracts
(D-013 stand-in for unsupported Gitea environments), the workflow skeletons
(pipeline.yml + issue-to-contract.yml), and the idempotent setup + verify
scripts. REQ-10/12 remain partial pending Phase 04 full implementation.
