osovv / grace-migrate

Agent-applied GRACE 3 to GRACE 4 migration workflow. CLI validates the result but does not convert or delete files.

<migration_safety>
Migration is copy-and-validate, not destructive conversion. Before writing .grace, inventory every legacy source, record a restorable backup path outside the proposed cleanup set, present the migration report, and wait for explicit write approval. Never create retroactive C-* bundles.
</migration_safety>

<workflow>

  1. Detect legacy docs and current .grace state. If .grace already exists, stop and ask whether migration should merge, replace, or abort.
  2. Inventory legacy source paths and create or verify a restorable backup. Record source coverage and backup evidence in the report.
  3. Map legacy requirements, technology, graph, verification, and operational content into the GRACE 4 layout. List ambiguities and unsupported structures rather than guessing.
  4. Produce references/migration-report-template.xml, review references/migration-checklist.md, and ask for explicit approval before writing .grace.
  5. Write .grace, then run grace lint --path <project-root> --assertions current and grace status --path <project-root> --json. Require status projectKind grace4 with no integrity errors, and record commands, exit states, and findings.
  6. If validation is not successful or generated coverage is incomplete, retain all legacy sources and stop.
  7. Detect git availability and worktree membership. If git is available for the project, record git status --porcelain --untracked-files=all before cleanup.
  8. Present an exact cleanup proposal containing only inventoried legacy paths. Ask for a separate explicit cleanup approval. For a dirty worktree or non-git project, require another explicit acknowledgement naming that risk.
  9. Archive or delete only the approved paths, record each result, and leave the backup intact. Do not use broad globs, hidden shell cleanup, or unreviewed recursive deletion.

</workflow>

<cleanup_preconditions>
Cleanup requires all of: complete inventory, restorable backup, explicit write approval, successful current lint, fresh status proving GRACE 4 with no integrity errors, verified generated coverage, git availability/worktree inspection, recorded porcelain output when applicable, exact proposed paths, separate explicit cleanup approval, and separate dirty or non-git risk acknowledgement when applicable. A missing gate means no cleanup.
</cleanup_preconditions>

<cleanupfailurerule>
If validation, git inspection, move, archive, or delete fails, stop immediately and state: "Legacy GRACE 3 artifacts remain untouched unless the failure output explicitly lists a completed move." Never retry destructive cleanup automatically.
