# Sync Tasks Reply in Russian. This is a thin, server-side trigger: the server enumerates, normalizes, and indexes the board. Do not enumerate tasks in the client and do not send credentials. 1. Resolve the repository path with `git rev-parse --show-toplevel`, then run `git -C <path> remote get-url origin`. For HTTPS and SSH URLs, remove the scheme, userinfo, and host; for scp-style remotes, remove everything through the host's first colon. Preserve every path segment after the host or scp colon, remove the leading slash, strip a trailing `.git`, then lowercase and validate the result as the canonical lowercase repository id (`owner/name` or `group/.../name`). Examples: - `https://gitlab.example.com/group/sub/repo.git` → `group/sub/repo` - `ssh://git@gitlab.example.com/group/sub/repo.git` → `group/sub/repo` - `git@gitlab.example.com:group/sub/repo.git` → `group/sub/repo` If origin is missing or ambiguous, ask for the complete namespace/repo id; do not guess from the directory name. 2. Resolve branch independently. Pass a non-null branch only when the user explicitly supplied or selected one and it is in the tracked branches list (`REVIEW_BRANCHES`). With no explicit tracked selection, pass `branch=null` so the server uses its primary tracked branch. Never infer the branch from the current worktree branch or blindly pass an untracked feature branch. 3. Call only repo mode with operation flags. The server owns effective board-policy re
