An occupied name otherwise fails +with guidance to use `connect `, and a project already connected to a +different tree fails rather than being silently repointed. Files created by a +failed create are removed; a destination that existed before the invocation is +never removed. + +`connect ` performs an exact managed-directory lookup. `connect +OWNER/REPO` reuses a matching checkout or clones it under the lowercased +repository name. Every selection is validated and safely classified as local +or GitHub state. Local-tree, repository, and unsafe-origin name collisions fail +before the project connection changes. Explicit connection switches are +automatic. Only a directory created by a failed clone is removed. + +`connect --tree-path ` attaches an exact, clean, fully valid Git root +with no symlink components in place and never copies, moves, or deletes it. +Trees without an origin classify as local state; credential-free GitHub +origins classify as GitHub state; all other origins are rejected. Stored- +connection validation accepts verified external paths while name-based +discovery remains restricted to the managed namespace. `list` reports valid, +clean managed trees as `{ schemaVersion: 1, trees: [{ name, tree }] }`; a +missing managed directory is an empty list and is never created by listing. + +## Synchronization and reading + +Local synchronization makes no network call and reports the checked-out branch +and exact `HEAD`. GitHub synchronization performs exactly one +`git pull --ff-only origin `, revalidates, then reports its +exact SHA. It does not discover or enforce the remote default branch and does +not report an `updated` flag. + +`read` returns a selected node and only its immediate indexed children. Callers +navigate narrowly from indexes rather than scanning the semantic tree. + +## Writing + +`prepare-write` synchronizes and creates a random `context-tree/write/*` branch +in an isolated worktree at the synchronized SHA. It returns only the worktree +path and schema version; no token, registry, manifest, lock, or preparation +record exists. + +`finish-write` requires that the supplied path is a real non-symlink directory, +belongs to the connected tree's Git common directory, uses the reserved branch +prefix, contains pending changes, and verifies as a complete Context Tree. +Calling it authorizes all pending changes. It stages everything and creates one +commit with `commit.gpgsign=false` while retaining the host Git identity. + +For local state it attempts one fast-forward merge into the connected checkout's +current branch. For GitHub state it attempts one non-force push to that branch. +Success removes the worktree and task branch. A non-fast-forward failure emits +`WRITE_OUTDATED` and preserves both. There is no rebase, race loop, semantic +conflict result, pull-request fallback, or abandoned-worktree cleanup. + +The write skill may prepare fresh and reapply the intended semantic change +once after `WRITE_OUTDATED`. A second outdated result is reported to the user. + +## Publication + +`publish` requires stored local state, a clean valid tree, and no existing +`origin`. By default it combines the authenticated GitHub login with the +managed tree name; an explicit validated `OWNER/REPO` may override it. +It runs one `gh repo create --private --source --remote origin --push`. + +After success, the connection is atomically updated to GitHub state. Clear +authentication failures produce `GITHUB_AUTH`; clear name collisions produce +`REPOSITORY_EXISTS`; uncertain or partial outcomes produce +`PUBLISH_INCOMPLETE`.
