What is this?

KIBBLE RUMBLE '94 turns Dan and Sanbo's daily morning breakfast into an interactive retro arcade championship. Powered by computer-vision detection and automated feeding analysis, each morning's feeding session becomes a playable arcade tape on the fictional NIKUKYU NK-500R color video monitor.

The Real Setup

This isn't a synthetic simulation — it runs on a real dual-feeder multi-camera setup in the home:

• Two Feeders, Two Bowls: Dan and Sanbo each have their own automated feeding station in separate areas of the home.
• Dan's Feeder (Lane 1): Monitored 24/7 by an overhead Tapo C210 infrared camera. This is the primary defense arena where Dan's breakfast is dispensed.
• Sanbo's Feeder (Lane 2): Monitored by a ground-level Logitech C925e USB camera. This is Sanbo's personal feeding station and home base.
• The Core Premise: The match outcome centers on whether Dan can successfully defend Dan's bowl.
• Sanbo Raids: Sanbo wins the championship game layer by crossing over and entering Dan's feeder area (canonical Lane 1 foreign arrival). Under house rules, entering is sufficient for raid success.
• Dan Counter-Raids: Dan can also sneak over to visit Sanbo's feeder, triggering bonus counter-raid events on the timeline!

Stage	Checkpoint / Layer	Real Project Implementation
Stage A	Physical Setup	Dual automated feeders & stainless bowls in separate rooms. Tapo C210 IR camera on tripod (Lane 1 / Dan) + Logitech C925e USB camera (Lane 2 / Sanbo). Raspberry Pi 5 with MOG2 motion capture and circular pre-roll ring buffer.
Stage B	Roboflow & YOLOv11	Curated "IR kibble" Roboflow project (930+ labeled frames, 5 domain classes: Dan, Sanbo, Dan_hand, Bowl, Kibble). Native 16:9 YOLOv11 detector (rect=True). Active learning auto-flagger (flagger.py) for continuous retraining. Historical V14 val benchmark: $mAP_{50} = 0.957$.
Stage C	Daily Telegram Ops	Automated breakfast analysis pipeline. Discrete event timeline extraction (food_dispensed $T+0$, cat_arrival, foreign_arrival, meal_finish). Feederbot daily report in private "feeder monitor" Telegram group with meal stats, health heartbeat, and annotated IR verification stills.
🔒 Gate	Fail-Closed Privacy Gate	On-premise security boundary: Wall-clock normalized to relative match time ($T+00:00$); fail-closed Person Safety withholding if human (Dan_hand) detected; 16:9 crop framing & background masking; audio stripped; 3+3 replay vault retention.
Stage D	Figma Experience Design	"Game Room v4" productization design system translating raw telemetry into a 1994 retro arcade championship. NIKUKYU NK-500R 14" Trinitron-style virtual CRT monitor with scanlines, audio toggles, lane switcher, and head-to-head arcade HUD.
Stage E	GitHub Public Web App	Curated technical core (fair-feeder/ domain models, schemas, and public test fixtures). Clean git history with zero household images or secrets. Showcase videos delivered via GitHub Release v1.0.0. Live playable daily match championship on GitHub Pages.

The Contestants

• 🥊 Dan (P1): 5-year-old Tuxedo cat. Defending champion at Dan's bowl. Role: defends his breakfast.
• 😼 Sanbo (P2): 1-year-old Calico cat. Agile challenger and raid specialist. Role: raids Dan's bowl.

Championship Rules

• Dan Win · Defended: Sanbo never enters Dan's bowl area, and Dan successfully clears his breakfast.
• Sanbo Win · Raid Success: Canonical TAPO foreign arrival of Sanbo at Dan's feeder. Under house rules, entering is sufficient for game-layer raid success.
• Dan Counter-Raid: Bonus event when Dan visits Sanbo's feeder (LOGITECH). Classed as Counter-Raid if following a Sanbo raid, otherwise Dan Raid.
• No Contest / Void: Unresolved match: unfinished breakfast, sensor blackout, or missing event timeline.

Privacy & Sanitization

All public media published to this repository is automatically sanitized:

• Relative Match Time: Household wall-clock times are replaced with relative match time ($T+00:00 = \text{Kibble Drop}$).
• Person Safety Rule: Fail-closed withholding of replay video if human presence is detected (Dan_hand).
• Privacy Masking: Household backgrounds and absolute timestamps are masked.
• Single-Camera Framing: Evidence stills and replays isolate the feeding area in clean 16:9 crops.
• No Audio: Surveillance audio is completely stripped from public replay clips.
• Deterministic Retention: Replay vault retains max 6 active matches (top 3 Dan wins + top 3 Sanbo wins).
