Captures everything needed to redeploy the two-display clock (hour on I2C 0x61, minute on I2C 0x63) on a fresh Pi: - Both systemd units (matrix0x61.service, matrix0x63.service) - Deployed Pimoroni script tree, including the local %I (12-hour) clock customization - Vendored upstream sources (ltp305-python, breakout-garden) so restore is fully offline-capable - Boot config snippet enabling I2C - install.sh that wires it all back up idempotently - Inventory doc cross-referencing every live-system path Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

LTP-305G live-system inventory
Snapshot of every LTP-305G-related path on matrixpi at the time this repo
was created. Use this to spot drift if anything is changed on the live system
without being committed back here.
Systemd units (root-owned)
/etc/systemd/system/matrix0x61.service— runsclock.py hour 0x61/etc/systemd/system/matrix0x63.service— runsclock.py minute 0x63
Both have WantedBy=multi-user.target and are enabled.
Deployed scripts (under dissimulo)

I2C bus state
i2cdetect is not currently installed on this system. Once i2c-tools is
installed, expect 0x61 and 0x63 to appear on bus 1 when both LTP-305G
breakouts are connected and powered.
