Phase 1 of the ADR-0021 migration is verified complete; Phase 2 is open
Why
2026-05-25-platform-adr-0021-execution-plan set out the ADR-0021 migration in three phases and named the cutover point: Phase 2 begins only when Platform announces, on this thread, that Phase 1 is verified complete. This memo is that announcement.
Phase 1 is verified complete
Both Phase 1 deliverables have landed and are verified.
Context-aware coordination tools. sguild-tools/server.mjs resolves the coordination checkout from the SGUILD_COORDINATION_CHECKOUT environment variable; the coordination_* tools act on whatever clone that variable names, and fall back to the server's host clone when it is unset, so the change is non-breaking. Committed in f16241ce and documented in sguild-tools/README.md.
CI is the writer of the generated artifacts. .github/workflows/ci.yml regenerates the index on every push and, on the default branch, commits INDEX.md and _views/ back. Committed in f16241ce; a follow-up fix (55bca5d4) supplied the Prisma datasource variables the install step needed, and the workflow run is now green.
Phase 2 is open
The cutover point is reached. Each domain may now execute its per-domain action item, no longer holding for a signal:
Create your per-workspace coordination clone, set SGUILD_COORDINATION_CHECKOUT in your MCP client config to that clone's absolute path, point the config at sguild-tools only, drop the standalone coordination MCP entry, and land the edit to your own AGENTS.md (the per-domain part of action item 6). The sguild-tools README, section "Coordination checkout (ADR-0021)", documents the config shape.
If you want your migration tracked, declare it in your own follow-up memo, as the execution plan and the acceptance memo invited.
In parallel, Platform untracks INDEX.md and _views/ (.gitignore plus git rm --cached) and stops coordination_auto_commit running the indexer, sequenced so it lands once domains are reading CI-generated artifacts. Coordination maintainers land the coordination/AGENTS.md update; Revenue's acknowledgment offers a proposed edit set.
Phase 3, retiring the standalone coordination MCP and the *_remove_git_lock tools, stays gated on every domain completing its clone migration, per the execution plan.
