-# Settings Migration Notes
-
-## Storage Layout
-
-- `.hmcl/config/launcher-settings.json`: workspace launcher settings.
-- `.hmcl/state/launcher-state.json`: workspace UI/runtime state.
-- `.hmcl/config/authlib-injector-servers.json`: workspace authlib-injector server list.
-- `.hmcl/cache/authlib-injector-server-metadata.json`: workspace authlib-injector server metadata cache.
-- `.hmcl/config/game-directories.json`: workspace game directory profiles in the `directories` list.
-- `HMCL_USER_HOME/config/user-game-directories.json`: shared game directory profiles in the `directories` list.
-- `.hmcl/config/game-settings.json`: workspace `GameSettings.Preset` entries.
-- `.hmcl/config/accounts.json`: workspace portable account metadata in the `accounts` list.
-- `HMCL_USER_HOME/config/user-accounts.json`: shared account metadata in the `accounts` list.
-- `.hmcl/private/account-private-data.json`: protected workspace account private data.
-- `HMCL_USER_HOME/private/user-account-private-data.json`: protected shared account private data.
-- `versions/<id>/.hmcl/config/instance-game-settings.json`: instance-specific game settings.
-- `HMCL_USER_HOME/state/*.migration-receipt.json` and `.hmcl/state/*.migration-receipt.json`: migration receipts.

-## Migration Scope
-
-- Only configuration formats used by `upstream/main` need migration support.
-- File formats introduced by this branch are still unstable and do not need compatibility with earlier revisions of this branch.
-- Do not add schema versions, migration paths, or compatibility shims only for intermediate file shapes produced by this branch.
-- Legacy config files are read as migration inputs and must not be rewritten.
-- Detached settings files should be created and saved only through the new storage model.
-- Do not encode `upstream/main` wording in production code, comments, logs, schemas, or tests; keep that local baseline note in this file only.
-
-## Migration Rules
-
-- Legacy `hmcl.json` and `.hmcl.json` are read as workspace migration inputs.
-- Legacy `accounts` fields in the workspace config are extracted into `accounts.json` and `account-private-data.json`.
-- Legacy shared `accounts.json` is used only as a migration input when `user-accounts.json` does not exist.
-- Legacy `authlibInjectorServers` and `addedLittleSkin` fields are extracted into `authlib-injector-servers.json`.
-- Legacy profile data from `configurations` is converted into `game-directories.json`.
-- Legacy profile global settings are converted into `GameSettings.Preset` entries.
-- Legacy per-instance `hmclversion.cfg` files are converted into `GameSettings.Instance` data.
-
-## Schema Policy
-
-- Detached settings files use `$schema` with `https://schemas.glavo.site/hmcl/<id>/<version>`.
-- Schema documents are stored in `docs/schemas/<id>/<version>.json` as the source files for the `/hmcl/` URL space.
-- Schema versions are written as `major.minor.patch`; `major.minor` may be accepted as patch `0` when reading.
-- Unsupported major versions are rejected.
-- Newer minor versions may be read but must not be overwritten.
-- Patch-compatible files may be saved while preserving the original schema string and unknown serialized members.
-
-## Settings Semantics
-
-- Instance settings resolve effective values from their selected parent preset.
-- Inheritable fields preserve explicit overrides and default to parent values when not overridden.
-
-## Verification Focus
-
-- Loading an old config should create detached files without losing selected account, selected directory, or selected instance state.
-- Editing accounts should update `accounts.json` and `account-private-data.json`, not `launcher-settings.json`.
-- Existing shared `accounts.json` should migrate to `user-accounts.json` and `user-account-private-data.json`.
-- Launch, export, install, and settings UI flows should read effective `GameSettings` values.
