CANONICAL_REPO_ROOT is normalized with cd ... && pwd, but CURRENT_REPO_ROOT comes from git rev-parse --show-toplevel, which resolves symlinks. If a user sets BRAINBAR_CANONICAL_REPO_ROOT to a symlinked path (common for ~/code style setups), the same checkout is misclassified as non-canonical and the script refuses the normal install path unless --force-worktree-build is used. This breaks canonical builds for valid environments and defeats the guard’s intent.
Useful? React with 👍 / 👎.

Fixed on current head afb9b485: brain-bar/build-app.sh now resolves the canonical repo root through pwd -P, so symlinked or ~-expanded canonical paths are compared by physical path instead of a raw string.

There was a problem hiding this comment.
The dirty check relies on git status --porcelain without forcing untracked-file mode, so a global/local status.showUntrackedFiles=no setting hides untracked files from DIRTY_STATUS. In that configuration, a repo with only untracked changes is treated as clean and bypasses the new --force-dirty safety gate, which undermines the explicit-review requirement this commit introduces.

Fixed on current head afb9b485: the dirty-tree guard now uses git status --porcelain --untracked-files=all, so untracked files are included and the install refuses a dirty repo unless the caller explicitly forces it.

When --force-worktree-build routes a non-canonical checkout to BrainBar-DEV-..., the script still operates on the shared LaunchAgent identity/file (com.brainlayer.brainbar under ~/Library/LaunchAgents) later in the same script, so this run rewires the user's canonical auto-start service to the DEV bundle. In the common case of testing from a worktree, that silently hijacks the production agent/socket target even though BrainBar.app itself is no longer overwritten, which undermines the safety goal of these guardrails.

When --force-worktree-build routes non-canonical builds to BrainBar-DEV-..., the script still uses the shared LaunchAgent label/file (com.brainlayer.brainbar in ~/Library/LaunchAgents) later in the install flow, so a worktree test build can silently repoint the user's canonical auto-start service to the DEV bundle. This undermines the safety guard because production startup behavior is still mutated whenever developers run forced worktree installs.

When --force-worktree-build is used, this branch intentionally preserves the canonical LaunchAgent/socket, but the script still runs lsregister -R "$APP_DIR" unconditionally just before this guard. Because Info.plist keeps the same CFBundleIdentifier and brainbar URL scheme, registering the DEV bundle can make brainbar:// resolve to the worktree app instead of the canonical install, which is a production-behavior mutation the new safety mode is trying to avoid.

Medium Risk
Changes the
brain-bar/build-app.shinstall/build behavior by blocking non-canonical and dirty-tree builds unless explicitly forced, and conditionally skipping LaunchAgent/socket management for DEV bundles; mistakes could disrupt local install flows.Overview
Adds guardrails to
brain-bar/build-app.shto prevent accidental overwrites of the canonical BrainBar install. The script now rejects non-canonical checkouts unless--force-worktree-buildis provided (routing those builds to aBrainBar-DEV-<branch>.apppath), and rejects dirty working trees unless--force-dirtyis explicitly passed.Introduces
--dry-runto validate these checks and print the resolved app path without building. DEV worktree builds also skip LaunchAgent install/bootout, socket cleanup, and socket readiness/connectivity checks to avoid disrupting the canonical service.Adds a new pytest suite
tests/test_brainbar_build_app_guards.pythat exercises canonical vs non-canonical behavior, dirty/untracked detection, branch-name sanitization, symlinked canonical roots, and environment isolation.Reviewed by Cursor Bugbot for commit c4e7744.
