 1. **Install flow**
 - `game_installer` builds menu from `.install/*.sh`.
 - Selected installer is sourced in the current shell.
-- If `.launch/<game>.game` exists and `.launch/<game>.sh` does not, the manager creates a symlink.
+- Shared downloads try `curl` first, fall back to `wget` when available, and reject obvious HTML error pages for unknown file types.
+- If `.launch/<game>.game` exists and `.launch/<game>.sh` does not, the manager creates a symlink using the repository root, even if the installer changed directories.
 
 2. **Launch flow**
 - `game_launcher` enumerates `.launch/*.sh` entries.

 - `game_removal` parses the first `installPath` match in launcher text, so comments containing `installPath` can break removal path detection.
 - Missing `run_update()` in `.update` scripts breaks update flow.
 - Bypassing shared download helpers risks cache and validation regressions.
+- Installers may change the working directory; repository-relative manager paths must therefore use the resolved script root rather than `${0%/*}`.
 - Use `alert` with its message arguments instead of chaining `alert` and `ui_msgbox`, otherwise `yad` users can get an extra acknowledgement dialog that does not include the actual guidance.
 - For `uv`-based Python games that need `speechd`, copy host Python `speechd` bindings into a game-local directory and export `PYTHONPATH` from the launcher.
