 All sub-agents operate exclusively inside `$WORKTREE_PATH`. The main working directory stays on `staging` and is never switched. If two Stories run in parallel, each has its own worktree — zero filesystem conflicts. Worktree isolation is **unconditional** regardless of story tier.
 
-Override the default worktree location by setting `GAAI_WORKTREE_BASE` (e.g., `export GAAI_WORKTREE_BASE=/tmp/gaai-worktrees` for cloud-synced repos).
+Default worktree location is `<parent-of-repo>/.gaai/<repo-name>/worktrees/<story-id>-workspace` — this keeps all GAAI worktrees grouped under a single `.gaai/` folder at the parent level, avoiding pollution of the parent directory when multiple projects share it. Override by setting `GAAI_WORKTREE_BASE` (e.g., `export GAAI_WORKTREE_BASE=/tmp/gaai-worktrees` for cloud-synced repos).
