Erich Blume 55a846eb25 Retire plans directory, convert migrate-forgejo-from-brew to mikado card

The plans/ directory predated the mikado method approach. Deleted all
completed and abandoned plans, converted the still-relevant
migrate-forgejo-from-brew into a lean mikado chain root card under
how-to/forgejo/, cleaned up dangling wiki-links across docs, and
fixed a stale "pre-commit" reference to "prek".

Frigate

Open-source network video recorder (NVR) with object detection. Runs cloud-free with all video stored locally on sifaka.

Cameras

Camera	IP	Location	Objects Tracked
GableCam	`192.168.1.159`	Front gable	person, car, dog, cat, bird

Camera credentials are stored in 1Password and synced via external-secrets to the frigate-camera Secret.

Detection

Object detection runs on ringtail's RTX 4080 via the ONNX detector with CUDA execution provider (TensorRT). The model is YOLOv9-c at 640x640 (yolov9-c-640.onnx, model_type: yolo-generic), which benefits from CUDA Graphs in Frigate 0.17. To re-export or change model size, use mise run frigate-export-model.

Two zones are configured: driveway_entrance (triggers review alerts for person/car) and driveway (triggers review detections).

Retention

Type	Duration	Mode
Continuous recording	3 days	all
Alert clips	30 days	active objects
Detection clips	14 days	motion
Snapshots	14 days	—

Storage

Mount	Backend	Size
`/media/frigate`	NFS PV on sifaka (`/volume1/frigate`)	2 Ti
`/db`	Local PVC (`frigate-database`)	SQLite
`/dev/shm`	Memory-backed `emptyDir`	512 Mi

Alerting (frigate-notify)

A separate frigate-notify pod (ghcr.io/0x2142/frigate-notify:v0.3.5) subscribes to Frigate's MQTT events via Mosquitto and pushes alerts to ntfy on the frigate-alerts topic. Alert messages include action buttons linking back to the Frigate review UI.

ntfy - Push notification delivery
sifaka - NAS storage for recordings
observability - Prometheus metrics at /api/metrics
