Two new test cases in test_sync_symlinks.py:
1. TestSyncScriptSymlink.test_skips_self_referential_via_directory_symlink
Unit test: verifies _sync_script_symlink() returns False and leaves
the real source file intact when dst_file is accessed through a
directory-level symlink that points back to the project scripts/ dir.
2. TestSyncScriptsToWorkspaces.test_no_self_referential_symlinks_when_workspace_scripts_is_dir_symlink
Integration test: simulates the install.sh scenario where
workspace-main/scripts -> project/scripts, then confirms that
sync_scripts_to_workspaces() does not convert any real source file
into a self-referential symlink."
sync_scripts_to_workspaces() previously used physical file copies. Scripts
that derive project root from __file__ (e.g. kanban_update.py) therefore
resolved to the workspace directory when run as a copied file, causing
tasks_source.json writes to land in the wrong location while the Dashboard
reads from the canonical data/ directory.
Replace write_bytes() with os.symlink() so __file__ always resolves back to
the project scripts/ directory. This ensures that all path-derived constants
(TASKS_FILE, DATA, etc.) point to the single canonical data/ folder regardless
of which agent workspace runs the script.
Added _sync_script_symlink() helper with:
- Idempotent re-runs (skip if link already correct)
- Automatic cleanup of stale physical copies and broken symlinks
- Full test suite (10 tests) covering creation, idempotency, replacement
of physical copies, broken symlinks, __file__ resolution, etc.
Closes#56
