v0.1.1 Fixed: - Store::discover now honors the SYNTHESIST_DIR environment variable. Previously ignored, causing synthesist's --data-dir flag to silently fall through to parent-walk and init a fresh empty store at cwd when no claim ancestry existed. Worktrees and detached checkouts regressed. - Explicit overrides that don't resolve to an existing store now fail loudly (missing path, not-a-directory, missing claims/genesis.amc). The silent auto-init on explicit paths is gone.
