dsh-session-sync

LIMITATIONS

已知限制

- **Object storage backend reserved.** `object-storage` is an interface placeholder and fails loudly at load; only `git` and `encrypted` are implemented. - **git required.** The plugin needs the `git` executable and the `subprocess` service; without them, sync operations fail with a clear reason (profiles keep booting). - **age is optional, external.** Encryption depends on the `age` binary on `PATH` (or `ageBin`). No `age` → plaintext fallback with a warning; a passphrase-protected identity cannot be used (decryption would block on a TTY prompt, so it fails closed). - **One repoDir per backend.** Switching between `git` and `encrypted` on the same `repoDir` is not supported; use a fresh worktree per backend. - **Session events on `0.1.0-rc.6`/`0.1.0-rc.8`/`0.1.1-rc.2`/`0.1.2-alpha.2`/`0.1.2-alpha.3`/`0.1.2-rc.1`/`0.1.7-alpha.2`.** The harness does not record `sync/*` event types, so the session-log appends are skipped (sessions keep loading); the plugin enables them automatically once a host records the types or exposes the `ignorable` envelope on `Session.append`. - **`approval` between turns.** `/sync` runs between turns, where the `approval` channel has no open turn to attach to; use `confirmVia: userQuestions` for command-driven sync, or drive sync through the tools inside a turn. The open-turn check reads the host `turnBoundary` session projection: a composition without `@deepseek-ai/dsh-session-projection` cannot verify the turn state and fails closed with that reason. - **Host-private artifacts stay host-private.** `session.lock` (the harness session lease) and `session.migration.*.tmp` staging files are never mirrored or deleted — they are runtime state, not syncable content. Session logs (`session.jsonl`, `session.v[1-9]*.jsonl[.zstd]`) remain the mirrored payload.
