migration.py DOX

Purpose

• Own the migration.py helper module.
• This module migrates legacy user data and runtime layout at startup.
• Keep this file-level DOX profile synchronized with migration.py because this directory is intentionally flat.

Ownership

• migration.py owns the runtime implementation.
• migration.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Top-level functions:
• startup_migration() -> None
• migrate_user_data() -> None: Migrate user data from /tmp and other locations to /usr.
• convert_agents_json_yaml() -> None
• _move_dir(src: str, dst: str, overwrite: bool=...) -> None: Move a directory from src to dst if src exists and dst does not.
• _move_file(src: str, dst: str, overwrite: bool=...) -> None: Move a file from src to dst if src exists and dst does not.
• _migrate_memory(base_path: str=...) -> None: Migrate memory subdirectories.
• _merge_dir_contents(src_parent: str, dst_parent: str) -> None: Moves all items from src_parent to dst_parent.
• _cleanup_obsolete() -> None: Remove directories that are no longer needed.

Runtime Contracts

• Helper modules own reusable framework APIs and must preserve public callers unless all callers, tests, and docs are updated together.
• Update this file whenever public functions, classes, persistence behavior, path/security assumptions, side effects, or cross-module contracts change.
• Observed side-effect areas: filesystem reads, filesystem writes, filesystem deletion, settings/state persistence, secret handling, scheduler state.
• Imported dependency areas include: helpers, helpers.print_style, json, os.

Key Concepts

• Important called helpers/classes observed in the source: migrate_user_data, convert_agents_json_yaml, extension.call_extensions_sync, _move_dir, _move_file, _migrate_memory, _merge_dir_contents, _cleanup_obsolete, subagents.get_agents_roots, files.get_subdirectories, files.list_files, files.deabsolute_path, files.exists, files.move_dir, files.move_file, files.get_abs_path, os.path.isdir, os.path.join, files.delete_dir, os.path.isfile.
• Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Work Guidance

• Preserve public helper APIs used by core code and plugins unless every caller is updated.
• Keep path, auth, secret, persistence, network, and subprocess behavior explicit and bounded.
• Prefer adding cohesive helper functions here only when behavior is reused across modules.

Verification

• Run targeted tests for changed helper behavior; run security regressions for auth, filesystem, WebSocket, tunnel, upload, or secret-handling helpers.
• Related tests observed by source search:
  • tests/test_browser_agent_regressions.py
  • tests/test_office_canvas_setup.py
  • tests/test_office_document_store.py
  • tests/test_speech_plugin_split.py
