+## path-cli 0.21.0 — 2026-08-26
+
+- **`path-cli`** (0.21.0): `path resume` takes `--remote <dest>` (Claude
+  only), `--dry-run`, and, with `--remote`, `-C <remote-dir>` for the
+  remote project directory (default: the local cwd with the local home
+  swapped for the remote home). The command resumes the session on an
+  ssh host under tmux. Two read-only probes report the remote home, the
+  claude path, tmux, the physical project directory, the tmux session
+  state, and the session file's existence, and the plan prints. Then a
+  live tmux session is attached to as is, a present session file is
+  launched as is, and an absent file is shipped over ssh stdin (0600;
+  written to a temporary name and renamed into place after a byte-count
+  check, so a present file is a complete file), launched, and attached
+  to. The session ID is the one `p export claude --derive-session-id`
+  derives. `--dry-run` stops after the plan. The transport is a new
+  internal ssh module, an in-process SSH client (`russh`); every remote
+  call has a wall-clock timeout. `scripts/resume-remote.sh` hands off to the
+  command after its bootstrap steps (VM creation, `--setup` seeding,
+  working-tree sync).
+- **`toolpath-cli`** (0.21.0): lockstep bump of the deprecated shim.
+
+## path-cli 0.20.0 — 2026-08-25
+
+- **`path-cli`** (0.20.0): `p export claude` takes `--derive-session-id`.
+  The flag renames the session to an ID derived from the input
+  document: a v4-shaped UUID from the first 128 bits of the SHA-256 of
+  the key-sorted compact JSON. The same document yields the same ID on
+  every run, so a second export of it into the same project is refused
+  instead of duplicated. It conflicts with `--session-id`. The
+  `--output` message names the session ID. `scripts/resume-remote.sh`
+  exports with the flag and reads the remote session ID back from the
+  JSONL.
+- **`toolpath-cli`** (0.20.0): lockstep bump of the deprecated shim.
+
+## path-cli 0.19.0 — 2026-08-24
+
+- **`path-cli`** (0.19.0): `p export claude` takes `--session-id <uuid>`
+  and `--cwd <dir>`. `--session-id` renames the session: the ID becomes
+  the conversation's session ID, every entry's `sessionId`, and every
+  `sessionId` key in every preamble line, nested keys included (Claude
+  Code copies the ID into `worktreeSession.sessionId` on
+  `worktree-state` lines); any UUID form is accepted and the output
+  uses the hyphenated lowercase form; with `--project` it names the
+  session file. `--cwd` roots the session: the directory becomes the
+  `cwd` of every entry that carries one; it must be an absolute POSIX
+  path in normalized form (no `.`, `..`, or empty component; one
+  trailing `/` is dropped), does not have to exist on this machine, and
+  conflicts with `--project`. Message content and tool results are not
+  touched. `scripts/resume-remote.sh` passes both flags, checks that
+  the output carries the remote cwd and ID, and ships it as is.
+- **`toolpath-cli`** (0.19.0): lockstep bump of the deprecated shim.
+
 ## toolpath-claude 0.13.0 — 2026-08-23
 
 - **Breaking:** `Conversation.segment_ids` replaces `Conversation.session_ids`.
