Cross-Repo Delivery at Scale: OpenSpec Change Protocols, Harness-Pinned Context
Knowing who owns the contract is not enough. This piece explains local-only, cross-business-repo, and shared-dependency work, with an executable sequence: contract prose in contracts repos, pointer-only impl proposals, parallel work after approval, final pin before merge. An Acme microservice map shows landing, plus a concrete cross-repo walkthrough of openspec /opsx-propose, apply, and archive commands and prompts.
