Cleanup errors +do not undo a successful publication and are reported in build metrics; retry GC. +`reclaimed_bytes` counts removed immutable files and revision directories. Native +provider cleanup reports separately; allocated file size and filesystem free space +may differ. Non-compacting GC can leave provider history physically allocated. + +## Consistency, leases and rollback + +Builds serialize under an OS writer lock, prepare shared immutable artifacts and +native versions, then publish one manifest using revision+epoch CAS in SQLite. +Failures leave the old head readable. Completed artifacts/embeddings can be reused +when a failed build restarts. A dead incremental builder is recognized after the +writer lock is released; GC can discard its unreachable output. The private Dolt server is identified by its absolute configuration path; after a +parent crash, the next locked operation stops that orphan before reopening the +repository. Unrelated Dolt processes are left alone. Legacy builds are +conservatively deferred for explicit recovery instead of guessed dead. + +An MCP read operation atomically acquires the head and a durable reader lease. +Every business tool call reads that revision's bindings, even if another process +publishes between calls. Calls renew the lease; `datamind_operation_close` releases +it. Default TTL is 1800 seconds; an expired operation errors and must be restarted, +never silently switches versions.

Crashed readers expire. + +```python +from datamind.config import DataSettings +from datamind.workspace import Workspace + +workspace = Workspace(DataSettings()) +workspace.configure_retention('recent', keep_last=10) +# graph_sources are prepared externally by the main Codex agent. +revision = await workspace.update('/absolute/sources', graph_sources=graph_sources) +async with workspace.reader(revision['workspace_revision']) as reader: + print(await reader.call('graph_schema')) +workspace.rollback(old_revision, expected_revision=workspace.current_revision) +``` + +Rollback changes only the catalog head, increments the epoch and preserves fixed +bindings. The next build uses the rolled-back head as its base; it does not reuse +an incompatible provider's mutable latest state. Protect rollback targets if a +latest/recent cleanup might otherwise remove them. + +## Migrate an existing Workspace + +1. Back up the storage directory and stop legacy snapshot writers. +2. Configure the native providers above, keeping the original embedding configuration. +3. Run `datamind workspace-migrate` (or `Workspace.migrate()` / MCP `workspace_migrate`). +4. Validate pinned reads, choose a history policy, preview GC, then apply if desired. + +Migration reads the current revision's frozen evidence, stored embeddings, +source-attributed graph and SQLite rows; it needs no original files or model calls. +It publishes a new V2 revision. Existing IDs keep their V1 contents and remain +readable until retention allows pruning; migration never silently deletes them. +Only the current head is migrated, not every historical snapshot. Keeping V1 +history therefore keeps its full snapshots. Tables without traceable source +identity or incompatible embeddings fail explicitly rather than guessing. +Independent live data is not migrated into a Workspace by this command. + +## API entry points + +MCP tools (with `datamind_` prefix): `workspace_history`, `workspace_retention`, +`workspace_gc`, `workspace_rollback`, `workspace_protect`, `workspace_migrate`. +Mutations require a write operation.
