Repository operating rules

This repository investigates an owner-controlled XGRIDS/LixelKity K1 as a black-box sensor. Preserve the device, the Mac, the working LAN, and raw evidence.

Non-negotiable safety boundaries

• Default to non-mutating discovery or read-only operations. CoreBluetooth BLE scanning on macOS is active discovery, not passive radio sniffing.
• Do not send BLE writes until the exact service, characteristic, framing, payload semantics, rollback, and expected state transition are documented.
• BLE notification subscription may perform the standard temporary CCCD write; disclose it explicitly and do not conflate it with provisioning writes.
• Do not fuzz, brute-force, upload firmware, delete device files, guess SSH/ADB credentials, or probe unrelated LAN devices.
• Network probes must target the confirmed K1 IP. A full home-subnet scan is not a default operation.
• Never place a Wi-Fi password in CLI arguments, logs, manifests, source, test fixtures, or Git history.
• Do not install Python packages globally. Use the repository-local .venv managed by uv.
• Do not install or alter Homebrew/system components unless the user explicitly authorizes that concrete change.

Evidence rules

• Reference inputs under docs/reference/ are immutable; write corrections in audits or ADRs.
• Every real experiment gets a session ID, UTC and monotonic timestamps, a redacted manifest, operator notes, and SHA-256 hashes for raw artifacts.
• Real PCAP, K1 projects, logs, images, point clouds, credentials, serials, and router client lists stay out of normal Git. Git LFS solves size, not secrecy.
• Synthetic or explicitly redacted fixtures may be committed under tests/fixtures/.

Implementation order

Follow the gates in docs/01_IMPLEMENTATION_PLAN.md. Do not build heavy decoders before BLE/Wi-Fi/data-session evidence exists.
