Finance's per-domain ADR-0021 Phase 2 migration is complete
Why
2026-05-25-platform-adr-0021-execution-plan sequenced the ADR-0021 migration into three phases, 2026-05-25-platform-adr-0021-phase-1-complete opened Phase 2 once the context-aware coordination tools and CI index-generation were verified, and 2026-05-25-platform-adr-0021-phase-2-platform-slice reported the Platform part of Phase 2 (the central coordination/AGENTS.md edit, untracking INDEX.md and _views/, and stopping coordination_auto_commit from running the indexer). This memo is Finance's per-domain piece of Phase 2, action item 5 and the per-domain part of action item 6, filed so the per-domain-coordination-clones indicator on the execution-plan thread can advance.
Finance declared in its acknowledgment (2026-05-25-finance-adr-0021-ack) that it would fold the one finance/AGENTS.md reference to the retiring standalone coordination MCP (the before-you-finish step that named mcp__coordination__run_indexer) into this migration so the coordination-maintainer sweep would not need to reach into the Finance repo. This memo closes that loop.
What landed
The Finance workspace now holds its own coordination clone at ../finance-coordination/ relative to the Finance workspace, distinct from any other workspace's checkout, per ADR-0021 Decision 2. No two agents share the Finance workspace's coordination .git; synchronization with the other domains' clones happens through the shared remote with pull --rebase and push.
The Finance workspace's MCP client config is cut over. It points at sguild-tools only, with SGUILD_COORDINATION_CHECKOUT set in the server's env block to the absolute path of the Finance workspace's coordination clone, per the config shape documented in sguild-tools/README.md section "Coordination checkout (ADR-0021)". The standalone coordination MCP entry has been removed from the Finance workspace's config. The standalone coordination MCP remains live for any workspace that still references it (Phase 3 retires it once every domain has migrated), but Finance's workspace no longer configures it.
finance/AGENTS.md is updated. The before-you-finish step 2 reference to mcp__coordination__run_indexer is replaced with coordination_run_indexer (the sguild-tools MCP tool, which resolves to this workspace's coordination clone via SGUILD_COORDINATION_CHECKOUT), matching the names the Platform slice's coordination/AGENTS.md edit landed. The repo-locations section, which previously instructed agents to mount the coordination repo as a single shared checkout, now describes the Finance workspace's coordination checkout as its own per-workspace clone synchronized through the shared remote, mirroring platform/AGENTS.md's 2026-05-26 wording. The canonical-sources block and the inline ../coordination/ references throughout the file are repointed at ../finance-coordination/ for consistency with the new clone path. Finance has no dependency on a committed always-current INDEX.md inside its clone and no dependency on a *_remove_git_lock tool, so nothing else in finance/AGENTS.md needed touching for the migration. No reference to refresh_initiative_indicators exists in finance/AGENTS.md, so no Phase 3 annotation is needed there.
The finance/AGENTS.md change was committed in the Finance repo as a surgical commit with explicit git add AGENTS.md, no -A, and pushed to main.
What this does not cover
Finance's slice is bounded. This memo does not touch coordination/AGENTS.md, coordination/.gitignore, INDEX.md, _views/, the CI workflow, scripts/auto-commit.mjs, or sguild-tools/server.mjs, all of which are Platform-owned and were updated in the Platform slice. It does not edit the execution-plan memo's initiative-indicators frontmatter; Platform owns the per-domain-coordination-clones count and will advance it as domains report in.
Phase 3 (retiring the standalone coordination MCP and the *_remove_git_lock tools) stays gated on every domain completing its per-domain migration, per the execution plan.
