What causes "read .beads/.gitignore: %w" in gastownhall/beads?

Check the path is a regular file and readable: `ls -la .beads/.gitignore` and `cat .beads/.gitignore`.

read .beads/.gitignore: %w

Error message

read .beads/.gitignore: %w

What it means

EnsureGitignoreForBeadsDir reads .beads/.gitignore and appends any runtime patterns bd requires. A read error that is NOT os.IsNotExist (the not-exist case is handled by writing a template) is wrapped as "read .beads/.gitignore". So this error means the file exists but could not be read — a permission or I/O problem, never a missing file.

Solutions

Check the path is a regular file and readable: `ls -la .beads/.gitignore` and `cat .beads/.gitignore`.
If it is a directory, remove it (`rm -rf .beads/.gitignore`) and re-run the fix so the template is written.
Fix permissions: `chmod u+rw .beads/.gitignore` or re-own the files (`chown -R $(whoami) .beads`).
If root-owned from a container run, redo the operation as the same user or fix ownership.

Example fix

// before
$ ls -la .beads/.gitignore
drwxr-xr-x  .gitignore   # accidentally a directory

// after
$ rm -rf .beads/.gitignore
$ bd doctor fix-gitignore
wrote .beads/.gitignore with required patterns

Defensive patterns

Strategy: validation

Validate before calling

info, err := os.Stat(".beads/.gitignore")
if err == nil && info.IsDir() {
	os.RemoveAll(".beads/.gitignore") // replace accidental directory
}
if err == nil && info.Mode().Perm()&0400 == 0 {
	os.Chmod(".beads/.gitignore", 0o644)
}

Try / catch

if err := EnsureGitignoreForBeadsDir(beadsDir); err != nil {
	if strings.HasPrefix(err.Error(), "read .beads/.gitignore") {
		// permission/I-O problem — check ownership and that it is a regular file
	}
	return err
}

Prevention

Run all bd commands as the user who owns the checkout (avoid sudo/root container runs).
Never create a directory named .gitignore; sync tools can do this by mistake.
Keep .beads file permissions at 0644/0755 in shared checkouts.
Re-check .beads contents after WSL/Windows cross-filesystem operations.

When it happens

Trigger: os.ReadFile(.beads/.gitignore) fails with a non-ENOENT error: the path is a directory named .gitignore, the file has restrictive permissions (unreadable by the current user), an I/O error occurs on the disk, or the file descriptor limit is exhausted.

Common situations: A directory was accidentally created at .beads/.gitignore (e.g. by a misconfigured sync tool); the repo was checked out by another user (root in a container) leaving root-owned files; filesystem mount issues or read-only remounts; Windows/WSL permission mismatches.
