Turn DeepSeek Harness (DSH) into a complete mobile PWA: secure remote access to your own DSH server + install-to-homescreen standalone app + offline capability + touch gestures + agent-done push notifications.

Built on the MIT dsh-mobile-gate secure-gateway base, with PWA differentiation.

Features

Module	What
📡 Secure remote access	Isolated child-process gateway. First-visit approval on the host, one-time token per device, per-IP rate limiting. DSH stays 127.0.0.1-only; the /api trust fence is untouched
📱 Real PWA	manifest.json + service worker → install to homescreen as a standalone full-screen app with icon, splash, theme-color, maskable assets
🌐 Offline	SW: shell assets cache-first, API network-first with cache fallback, offline fallback page
👆 Touch gestures	Pull-to-refresh, edge-swipe back, pinch-to-resize font (resettable)
🔔 Agent-done push	Web Push when the agent finishes a turn, even when the phone shows another app (opt-in)
📐 Touch layout	44px targets, safe-area, full-screen dialogs, compact type, horizontal-scrolling code — desktop never affected
🔒 Desktop unaffected	Every rule is rooted at html[data-lan-device="phone"] or an @media(max-width:820px) that excludes data-lan-device="desktop"

Architecture

Phone ──> gateway (isolated Node child · 0.0.0.0:3088)
            ├─ not approved       -> "waiting host approval" page (polls /lan-gate/admin)
            ├─ approved + token   -> reverse proxy to DSH Web UI (127.0.0.1:3080)
            │        └─ HTML injected: manifest link + PWA bootstrap + touch CSS + randomUUID polyfill
            ├─ /pwa/*             -> serves manifest / sw.js / app.css / icons / offline.html
            ├─ /pwa/push/*        -> subscribe & send agent-done notifications
            └─ over rate          -> 429 page
Host 127.0.0.1:3088/lan-gate/admin -> approve / deny / revoke devices, pick access mode (phone/desktop/auto)

Quick start (on your own DSH server)

git clone https://github.com/<you>/dsh-mobile-pwa.git
cd dsh-mobile-pwa
dsh plugin --profile web add ./dsh-mobile-pwa

Or static-mount via cordis.patch.yml.example.

Env config

LAN_GATE_PORT (3088) · LAN_GATE_HOST (0.0.0.0) · LAN_GATE_TARGET_PORT (3080) · LAN_GATE_RATE_LIMIT (120) · LAN_GATE_VAPID_PUBLICKEY (empty, for push).

Flow

1. Start DSH + this plugin → sees [lan-gate] listening on 0.0.0.0:3088 -> 127.0.0.1:3080 (pwa=on).
2. Phone → open http://<your-ip>:3088 → "waiting approval".
3. On the host → open http://127.0.0.1:3088/lan-gate/admin → approve the device, pick phone.
4. Phone → refresh → DSH UI, PWA-injected.
5. Browser menu → Add to Home Screen → standalone app.
6. (Optional) enable agent-done notifications from the injected hint.

Test locally

npm test   # boots a mock upstream, asserts /pwa assets, HTML injection, status

Layout

lan-gate.mjs (Cordis entry) · dsh-push.mjs (optional push host plugin) · lib/lan-gate-server.cjs (zero-dep gateway) · pwa/ (manifest, sw.js, inject.js, touch-gestures.js, app.css, offline.html, icons) · cordis.patch.yml(.example) · test/

See AGENTS.md for development conventions (do not break isolation / CSS prefix rules / stable selectors).

Security

Installing a plugin runs third-party code with your own permissions. Run only on your own server, keep credentials away, and audit lib/lan-gate-server.cjs changes. Always use approval + tokens for remote access; never expose the gateway port raw on the public internet.
