## What changed
- Detect and import supported Cursor settings, sandbox permissions, MCP servers,
project instructions, hooks, agents, commands, plugins, and recent chat
sessions.
- Update the `/import` flow to check Claude Code and Cursor, prompting for a
source when both have importable data.
- Add `migrationSource` to the app-server detect and import requests so each
operation uses the selected adapter, while retaining `source` for import
attribution and backwards compatibility.
## Testing
- Add coverage for Cursor config conversion, hooks, plugins, session discovery
and conversion, app-server imports, and TUI source selection.

## What changed
- Correlate MCP server attribution in imported session records with connector
metadata, and persist normalized connector names in the session import ledger.
- Extend `externalAgentConfig/import/readHistories` with connector candidates,
including each connector's display name, imported-session count, and detection
source.
## Testing
- Cover connector detection through the session import and history-read flow.
- Verify candidate aggregation uses the latest import for each source session.

## What changed
- Add `subErrorType` to external agent config import failures and carry it through progress and completion notifications, persisted import histories, and analytics.
- Expose plugin store failure subtypes from `PluginInstallError` so manual installs and imported plugins report details such as `failed_to_copy_plugin_file` while failures without a subtype remain `null`.
- Keep existing persisted import records compatible by defaulting the new field when it is absent.
## Testing
- Cover store I/O subtype extraction, analytics serialization, persisted import histories, and migration notification fixtures.

## What changed
- Add an optional `source` selector to `externalAgentConfig/detect`, while preserving the existing behavior for omitted, `null`, and unrecognized values.
- Pass `claude-code` as the source for TUI detection and import requests.
- Move source-specific migration behavior behind an adapter boundary and consolidate session migration into `codex-external-agent-migration`.
## Testing
- Cover explicit, omitted, and unknown detection source values with app-server protocol tests.
- Add unit coverage for the extracted migration and hook helpers.
