-Expose `GET /api/experimental/migration/v1` for status and a blocking `POST /api/experimental/migration/v1` to run or

-advances only after a session transaction commits. The POST returns `{ status: "completed" }`. Do not add a background
-job or streaming progress protocol. Interrupted calls resume from the stored cursor.
-Initially, only interactive TUI startup performs this check; noninteractive run, ACP, raw API, service, health, version,

-
-Use V1 assistant `parentID` only while pairing compactions and skipped subtasks with their originating user messages. Do
-not persist it in ordinary V2 assistant rows; V2 uses ordered history rather than user/assistant parent links.
-
-Ignore the optional V1 assistant `structured` output value. V2 has no equivalent top-level assistant field, and visible
-text and tool content are migrated separately. Retain the original structured value only in the V1 `message` row.
-
-Ignore V1 assistant `mode` and historical `path` (`cwd` and `root`). Mode is redundant with the preserved assistant
-agent, and historical filesystem paths do not belong to the V2 assistant message contract. Retain them only in the V1
-`message` row.
-
-For assistant finish reasons, preserve `stop`, `length`, `tool-calls`, `content-filter`, `error`, and `unknown`. Map every
-other nonempty V1 finish value to `unknown`, and leave the field absent when V1 omitted it. Do not retain unrecognized raw
-finish values in metadata.
-
-Map V1 assistant errors into the current V2 `{ type, message }` storage shape. Normalize Auth, content-filter, context
-overflow, structured-output, output-length, aborted, API, and unknown errors to the established V2 string conventions,
-preserve the message, and discard V1-only retryability and raw provider details.
-
-Ignore V1 `retry` parts. Do not populate the V2 assistant `retry` field during migration; historical retry state is not
-useful enough to preserve. The original retry rows remain in the V1 `part` table.
-
-Do not emit V2 assistant content for V1 `step-start` and `step-finish` parts. Use the first available
-`step-start.snapshot` as `assistant.snapshot.start` and the last available `step-finish.snapshot` as
-`assistant.snapshot.end`. Continue to source finish, cost, and tokens from the assistant message itself. Ignore step
-markers without snapshots.
-
-Do not emit assistant content for standalone V1 `snapshot` or `patch` parts. If no start snapshot came from `step-start`,
-use the first standalone snapshot value, then the first patch hash as a final fallback. Only `step-finish.snapshot` may
-populate the end snapshot. Merge patch file lists into `assistant.snapshot.files` in first-seen order with duplicates
-removed.
-
-V2 follow-up: replace the open `SessionError.Error` string shape with a properly typed persisted error union. This is not
-a blocker for the V1 migration, which should target the current storage contract.
-
 V1 synthetic content is represented by user text parts with `synthetic: true`, not by a separate message role. A V1 user
 message whose visible text parts are all synthetic should become a V2 `synthetic` message. If a V1 user message mixes
 ordinary and synthetic content, preserve the ordinary content in the V2 `user` row and emit the synthetic content as an
 adjacent V2 `synthetic` row. Ignore text parts marked `ignored`, matching V1 model-history behavior.
 
-For an ordinary V2 user message, take visible V1 text parts that are neither ignored nor synthetic, preserve part order,
-and join their text with `"\n\n"`. Use an empty string when the message contains attachments but no ordinary text.
-
-Ignore the optional V1 user-message `system` override. Do not create a V2 system message or preserve the override in
-metadata. The original value remains in the V1 `message` row.
-
-Ignore the optional V1 user-message `tools` map. It represented request-time tool enablement for a historical step and
-must not affect future V2 execution. The original value remains in the V1 `message` row.
-
-Ignore the optional V1 user-message `format` field and its schema. It controlled structured-output behavior for a
-historical request and must not affect future V2 runs. Preserve visible assistant text normally; retain the original
-format only in the V1 `message` row.
-
-Ignore V1 user-message `summary` metadata, including title, body, and diffs. V2 user messages have no equivalent field,
-and session-level summary data is already persisted separately. Retain the original summary only in the V1 `message`
-row.
-
-Map V1 `agent` parts into the V2 user message's `agents` array in part order. Preserve `name`. When the V1 part has
-`source`, map its `value`, `start`, and `end` into the V2 attachment's `mention.text`, `mention.start`, and `mention.end`.
-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
-from database contents alone. Convert persisted `data:` URLs; represent non-embedded `file:`, HTTP, and other external
-URLs with deterministic text rather than fetching them. Keep the original V1 `part` rows unchanged.
-
-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
-attachment mention. Leave `description` unset and preserve file-part order in the V2 `files` array.
-
-For a non-embedded V1 file, do not create a V2 file attachment. Append
-`[Attachment unavailable after migration: <name-or-url> (<mime>)]` to the V2 user text in original part order, separated
-by blank lines. Prefer the V1 filename, then resource URI, then part URL for the label. The original URL remains only in
-the preserved V1 `part` row.
-
-For a synthetic row split from a mixed user message, derive a generated-looking ID from the source message ID. Preserve
-the source ID's 12-character timestamp component and replace its 14-character random component with a deterministic
-base-62 encoding of a hash of `v1-synthetic:` plus the source message ID. If that candidate collides with an existing or
-derived message ID, deterministically retry with an incrementing salt. Place the synthetic row immediately after its
-source user row. Entirely synthetic messages continue to reuse their original message ID.

+## 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
-successfully committed session advances the cursor.
