What is dsh-session-sync?

Cross-device session sync for DeepSeek Harness — a dedicated git mirror of your session store.

Sync your sessions between devices, keep both sides on any conflict, never lose a turn.

The same run, animated.

Compatibility

Surface	Status
Harness	DeepSeek Harness dsh-v0.2.1-alpha.1 (GitHub tag, verified 2026-09-25: full gate chain against the pinned 0.1.7-rc.2 peers). npm dependency line 0.1.7-rc.2, peers `>=0.1.2-rc.1 <0.2.0
Node	^22.19.0 || >=24.0.0
Platforms	Anywhere git and DSH run (git-based mirror; no platform-specific code)
Model	Text-only models fully supported; no vision or extra model capability required

What you get

dsh-session-sync mirrors your DSH session store into a dedicated git worktree and syncs it to a remote you control — no cloud service, no third-party storage:

• /sync command — status (branch, sanitized remote, ahead/behind, dirty files, forks), diff, log, pull, push, help.
• sync_status / sync_pull / sync_push tools — the same surface for the model, inside a turn.
• Append-only conflict resolution — session logs are append-only; on any divergence the plugin keeps both sides (local version kept, remote version preserved as fork files) and never silently overwrites. Diverged sessions can also fork at the session level.
• Auto modes — pull on start, push after every closed turn, and periodic pull, all configurable and all reversible.
• Confirmation-gated writes — pull/push ask first (through userQuestions or approval); read-only surfaces never ask; with no answerer the operation fails closed.

device A                              remote (your git repo)                  device B
$DSH_HOME/sessions ──mirror──▶ commit ──push──▶ [sessions] ──pull──▶ merge (keep-both + fork)

Quick start

dsh plugin --profile web add github:PerryLink/dsh-session-sync

# 1. install the bundle into your profile
dsh plugin --profile web add github:PerryLink/dsh-session-sync

# or from npm (published releases)
dsh plugin --profile web add dsh-session-sync

# 2. point it at a private git remote and verify the row
dsh --profile web --dump-config | grep -A2 'id: session-sync'

Then set the remote in your profile patch (a private repository is the baseline) and sync:

- insert:
    - id: session-sync
      name: dsh-session-sync
      config:
        remote: git@github.com:you/your-dsh-sessions.git

> /sync status
> /sync pull
> /sync push

Configuration

All tunables are Schemastery Config fields (changeable from cordis.yml). An id-targeted override replaces the whole row — restate every key you need. cordis.patch.yml documents each key inline.

Key	Default	Meaning
enabled	true	Master switch; false unregisters the command, tools, listeners, and auto modes
backend	git	Sync backend: git (plaintext mirror) or encrypted (age-encrypted mirror content)
sessionRoot	''	Session store root; empty = $DSH_HOME/sessions (both missing fails load)
repoDir	''	Sync worktree root; empty = $DSH_HOME/dsh-session-sync/repo
remote	''	Remote address (required before pull/push; status/diff work without one)
branch	main	Remote branch name
gitBin	git	git executable path
ageBin	age	age executable path (probed for backend: encrypted; missing degrades to plaintext)
ageRecipient	''	age recipient (public key or identity string); empty = cannot encrypt, degrades to plaintext
ageIdentity	''	Path to a passphrase-less age secret key for decryption; empty = cannot decrypt, degrades to plaintext
autoPullOnStart	false	Pull once when the plugin mounts (config is the grant; no re-confirm)
autoPushOnTurnEnd	false	Push after every closed turn
pullIntervalMinutes	0	Periodic pull every N minutes (0 = off, max 10080)
confirmVia	auto	Confirmation channel: auto (userQuestions first, then approval), userQuestions, approval
graceMs	10000	Grace period for git kills (ms)
commandTimeoutMs	120000	Per-command timeout (ms)
maxOutputBytes	262144	Per-stream collected-output cap (bytes)
commitName	dsh-session-sync	Commit author name
commitEmail	dsh-session-sync@localhost	Commit author email
registerCommand	true	Register the /sync command
registerTools	true	Register the sync_* tools when the tools service is present

Example override in your profile patch:

- insert:
    - id: session-sync
      name: dsh-session-sync
      config:
        remote: git@github.com:you/your-dsh-sessions.git
        branch: main
        autoPushOnTurnEnd: true
        pullIntervalMinutes: 30
        confirmVia: userQuestions

Tools & surfaces

Surface	Read-only	Needs confirmation	Notes
/sync status	✅	—	Branch, sanitized remote, ahead/behind, dirty files, fork files, last pull/push
/sync diff	✅	—	Uncommitted changes + HEAD..remote stat (read-only)
/sync log	✅	—	Last commits in the sync repository
/sync pull		✅	Fetch + merge with keep-both semantics; local kept, remote preserved as forks
/sync push		✅	Mirror + commit + push; never force-pushes, reconciles and retries once on rejection
sync_status	✅	—	Same facts as /sync status for the model
sync_pull		✅	Model-callable pull
sync_push		✅	Model-callable push

Permissions & data

• Permissions: mutating operations cross the confirmation gate (confirmVia); the plugin never re-implements or bypasses the harness's userQuestions/approval services. Auto modes are covered by the config grant and never re-confirm.
• Data: sync metadata (device id, last pull/push, last push head, last error) lives in the session-sync storage domain. Session files are copied as opaque bytes — the plugin never parses them. The device id is also written to device.txt in the sync repository for cross-device fork attribution.
• Session log: sync/push, sync/pull, and sync/conflict are declared in types.d.ts; they are appended only when the host records the types (see Known limitations). Everything written or shown is sanitized. The one durable message the plugin writes — the conflict fork notice — carries the plugin's own producer-owned source kind (dsh-session-sync); the harness retired the shared plugin kind and refuses it when a session is read back.

Security boundaries

• Never silently overwrite. The append-only three-way merge keeps both sides on any divergence, including delete/modify (modified bytes kept, deletion intent honored); fork files are never deleted, and git never force-pushes, resets, rebases, or switches branches.
• Path containment. Files are mirrored as opaque bytes with symlinks refused and every joined path containment-checked (PATH_UNSAFE fails loud).
• Sanitized output. Remote-URL credentials, tokens, and key=value secrets are redacted before reaching the model or the log; path display refuses anything outside its root.
• No credential storage. The plugin stores no credentials; git credentials live in your normal git credential helper. age keys are read from paths you configure (ageIdentity); keys never enter the sync repository.
• Git hardening. Git runs with GIT_TERMINAL_PROMPT=0 and GIT_OPTIONAL_LOCKS=0, deadline- and signal-bounded, with a per-stream output cap.
• Fail closed. A missing confirmation answerer, a missing remote, or an unsafe path refuses the operation loudly.

Encryption & threat model

backend: encrypted adds an optional age layer above the mirror: session bytes are encrypted into encrypted/**/*.age files before they are committed and pushed, and decrypted back to the local plaintext mirror before merging. The three-way merge always runs on plaintext locally, so the append-only keep-both semantics are unchanged.

What the encryption protects:

• Mirror content at rest in the remote. The session files you push are age ciphertext; the remote host, its operators, and anyone who clones the repository do not see plaintext session bytes without the private key.

What it does not protect (the boundary):

• Keys and age identities are yours to manage. The recipient/identity files are never shipped, stored, or rotated by the plugin. If a key leaks, the mirror content it protects is exposed. Use a passphrase-less identity and keep it out of the repository.
• The remote is still a private repository in practice. git metadata — commit messages, the .gitignore, the encrypted/ path structure, branch names, and push/fetch activity — remains visible to the remote host. Encryption hides the content, not the fact that you sync, nor the shape of your session tree.
• Plaintext still exists locally. The mirror at <repoDir>/sessions/ is plaintext on disk; encryption protects the transmitted/remote copy, not local disk encryption or the live session store.
• graceful degradation means plaintext. With backend: encrypted, if age is missing, or ageRecipient/ageIdentity is empty, the plugin falls back to the plaintext git path and warns explicitly in the status/log — it never silently pretends to encrypt. Check /sync status for the warning before trusting the remote as encrypted.

Baseline: with backend: git (the default), session bytes are stored unencrypted in your git remote — use a private repository.

Known limitations

• 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.

Development

pnpm install                                       # node ^22.19 || >=24
pnpm run typecheck && pnpm run typecheck:ci        # tsc --checkJs against the published 0.1.7-alpha.2 peers
pnpm test                                          # node --test (13 test files; the engine git suite skips without git)
pnpm run verify:self-contained                     # dependency specs resolve from the registry
pnpm run verify:artifacts                          # shipped files present + index.mjs importable
pnpm run check:readmes                             # five-language README consistency
pnpm pack                                          # the published tarball

There is no build step: pure ESM, index.mjs and lib/ are the shipped artifacts.
