A wrong elevator call is a safety event, so the system is built to send nothing until it is certain — and even then, the certified lift controller decides.

• Classifies HUMAN, CARGO, MIXED, and EMPTY from a single USB camera feed
• Pipeline is camera → RF-DETR on TensorRT → centroid tracker → sliding-window median smoother → weighted-vote fusion → safety guards → dispatch adapter
• DISPATCH_MODE defaults to shadow, so no command reaches a lift until it is switched on deliberately

• Postgres
• Mosquitto MQTT
• Grafana

A wrong send is a legal event, so the send stage is dry-run by default and every message must pass compliance checks before it can leave.

• Four stages — discover, draft, send, pipeline — each runnable on its own
• Uses a minimal X-Goog-FieldMask against the Google Places API (New) to find businesses with no websiteUri
• Drafts personalised outreach with the Claude API (claude-haiku-4-5)

An unreviewed agent commit is a correctness event, so the roles are isolated by branch and no agent may approve its own work.

• Planner plans, Builder implements, Reviewer reviews — each in its own sandbox and on its own Git branch
• Handoffs are an append-only JSONL log, so the decision trail survives a session ending
• A build is merged only after a Reviewer record with approve status

• TypeScript
• Rust
• Git

A bot with write access to someone else's board is an authorization problem before it is a Discord problem, so the role allowlist is enforced when the flow opens and re-checked at the moment of the write.

• Authenticates as a GitHub App with short-lived per-installation tokens; no personal access token is stored
• The role allowlist is enforced at the trigger and re-checked at write time
• A rapid double-submit creates at most one Issue — the first submit claims the flow and a concurrent second is refused

• discord.js
• GitHub Apps
• GraphQL

The audio path refuses to depend on anything that rots: yt-dlp resolves metadata only and ffmpeg reads the media URL itself, so when YouTube rotates its player, updating one pinned binary is the whole fix.

• Fourteen slash commands, and no Lavalink, no Java, no Python and no native Opus or sodium package — Node 22's aes-256-gcm covers voice encryption and ffmpeg does the Opus encoding
• The install script downloads the pinned binary and the SHA2-256SUMS file from the same release, verifies the checksum, and refuses to install a binary that does not match
• Preflight checks ffmpeg, the opus muxer, yt-dlp and the environment before the bot logs in
