-Omit `agents` when there are no agent parts.

-Do not read the filesystem or network while migrating V1 file attachments. Attachment migration must be deterministic

-
-For a V1 file backed by a `data:` URL, decode the URL and normalize its payload to base64 for the V2 attachment's `data`.
-Preserve `mime` and optional `filename` as `name`. Use a V2 `uri` source with the original URI for a V1 resource source;
-otherwise use an `inline` source. When V1 source text metadata exists, map its `value`, `start`, and `end` into the V2

 New nullable session columns, including `fork_session_id`, `fork_boundary`, and `time_suspended`, require no explicit

-## Execution
+## Verification

-Before transforming V1 rows, look for `opencode-next.db` in the data directory. This file was used by pre-launch V2
-builds. Open it read-only with Bun SQLite and copy its `project`, `session`, and `session_message` rows directly into the
-current `project`, `session_v2`, and `session_message` tables. Existing current projects and Sessions win ID collisions.
-Do not copy its durable events or runtime caches; initialize each imported Session's `event_sequence` watermark from its
-maximum message sequence. Commit each imported Session independently and leave the source database untouched.
+The canonical migration test should seed representative V1 sessions, messages, parts, todos, projects, accounts,
+credentials, permissions, shares, and workspaces. After migration, it should verify:

-The previous V2 import is part of this migration and uses the same completion marker. It needs no source-specific cursor:
-the destination Session row is the per-Session idempotency boundary, so a retry skips transactions that already committed.
-
-Store V1 backfill state in `kv`; do not retain a dedicated `data_migration` table. Store the last successfully migrated
-session ID under `migration.v1-v2.session.cursor` and write `migration.v1-v2.completed` with value `true` after every
-session finishes. Delete the cursor key on completion and return immediately on later calls when the completion key
-exists.
-
-Absence of the completion key means migration is required, including on a fresh database. Running the endpoint against a
-database with no sessions completes immediately and writes the completion key; fresh database initialization does not
-seed migration state specially.
-
-Process sessions in stable ID order. Rebuild one session in one transaction, including its `session_message` rows,
-session-level backfills, `event_sequence` watermark, and cursor update. If interrupted during a session, that transaction
-rolls back and the next endpoint call retries the same session. If it committed, the next call continues after the stored
-cursor. Mark the migration complete after the final session and return immediately on later calls.
-
-Ensure the global project exists using the current platform's filesystem root as its worktree. Process every `session`
-row, including archived, root, child, and empty sessions, as well as sessions whose messages are all skipped or internal.
-Reassign beta and V1 Sessions whose referenced project row is missing to the global project and log a warning. Each
