Release xCreen 2.0.0 · Al-ex-W/xCreen

Screen memory for Hermes — now with Hermes on your Mac or on a home server.

What's new

Client and server. The Mac app now only captures and uploads. xcreen-server runs next to Hermes Agent — on the same Mac (complete install) or on a Linux/macOS machine you reach over Tailscale (split install) — and owns the screen history, the Hermes session and your notes. Same code either way, one stable protocol. Design: client and server.
Never digests on the wrong model. Automatic batches wait until the xCreen default model is applied, and resume on their own when it becomes available.
Smaller history. Screenshots are recompressed to JPEG once their batch is digested (~8× smaller, ~95% of OCR-readable words kept); the digest itself always sees the lossless capture.
Keeps capturing offline. If the server is unreachable, the Mac queues captures in a private outbox and uploads them later (xcreen flush to push now).
New commands: xcreen server, xcreen flush; on the server xcreen-server init|serve|token|doctor|config|migrate-journal.

Hermes on the same Mac: bash scripts/install.sh (upgrades 1.x in place, keeping your history, session and settings).
Hermes on a server: bash scripts/install-server.sh --tailscale there, bash scripts/install.sh --client --server http://SERVER:8765 on the Mac.
Moving an existing install to a server: see INSTALL.md.

The zip below contains the Mac app only (not notarized: System Settings → Privacy & Security → Open Anyway). The server installs from a checkout.

With a split install, screenshots, OCR, receipts and notes live on your server; secure it accordingly. Requests are authenticated with a bearer token; plain HTTP is only accepted on loopback, private networks and Tailscale. See SECURITY.md.
Digests of evidence that was already uploaded continue while the Mac is locked or asleep (Integrity ON still stops them).

Full details: #3, #2.
