Cinepatch: Theater Ledger

Cinepatch is an offline system ledger for home-theater owners who need to remember more than a single receiver preset. Preserve the room geometry, device chain, cable path, input mode, speaker layout, and calibration snapshot that actually worked. KEY FEATURES - Room, screen, seat, speaker, projector, and equipment map - Source-to-display and source-to-speaker signal-path records - Aspect, screen height, throw distance, viewing angle, and delay math - Calibration snapshot comparison with firmware and service history - Optional local photos through Apple's Photos picker - Local PDF project brief - 175 original offline reference plates - No account, ads, analytics, tracking, subscription, or network requirement Cinepatch documents user-entered AV setups and estimates geometry. It does not control devices, certify HDMI compatibility, perform acoustic calibration, prescribe electrical work, copy vendor databases, or replace manufacturer instructions and qualified installation guidance.
