Sceptre Live

Real-time multilingual sermon operations platform. A Tauri+Rust desktop app compiled from an Architectural Genome in 4 hours. Two-flow translation contract enforced at compile time — canonical Bible text is never put through MT.

Input — what the founder described

A live multilingual sermon operations platform for ministry teams. Speakers use a Tauri desktop app. During a live sermon, the platform streams speech-to-text via Azure (primary) or Deepgram (fallback), translates each utterance in real-time via either NMT (for general language) or canonical Bible-verse lookup (for scripture — never use MT for scripture, always look up the canonical translation), and fans out translated text + audio to per-language presentation windows. Operator and congregation roles. Local SQLite for offline resilience. Cloud sync optional.

Output — what Archiet compiled

Genome primitives6 realtime

StackTauri + Rust + React

Provider adapters4 (Azure, Deepgram, DeepSeek, NLLB)

Retrieval indexes3 (KJV, ESV, NIV)

Runtime services3 (session, audio, sync)

Two-flow contractenforced at compile time

The Architectural Genome

Six first-class primitives that Archiet compiled into working Rust code. None of these exist in Lovable, Bolt, v0, or Cursor.

provider_adapters[]

Azure Speech STT + Deepgram fallback with circuit breaker. DeepSeek MT + NLLB for general translation. Token-mint auth pattern for browser SDK.

retrieval_indexes[]

Three canonical Bible corpora (KJV, ESV, NIV) with per-book parsers, embedding indexes, and confidence-aware rerankers. Canonical text resolved by lookup, never MT.

streaming_pipelines[]

Two pipelines: translation_mode=nmt (general language, MT allowed) and translation_mode=canonical_lookup (scripture, MT forbidden). Two-flow contract is a compile-time invariant.

output_channels[]

Per-language WebSocket fanout to presentation windows. Sync + reconnect contracts baked in. Partitioned by locale.

runtime_services[]

SessionManager, AudioCoordinator, and CloudSyncService — long-running stateful services with FSM, health pulse, and fallback policy.

desktop_runtime

Tauri 2 shell declaration. Presence flips the generator into desktop mode: no Flask Blueprint injection, no Terraform, no Kubernetes configs.

Why this product class matters

This is a product that Lovable, Bolt, or v0 cannot build. It requires:
• Tauri desktop + Rust backend (not a web runtime)
• Two-flow translation contract enforced at compile time (not documentation)
• Canonical Bible lookup that hard-bans MT providers — a correctness invariant, not a config toggle
• Streaming pipelines with backpressure and partial/final emit semantics

Archiet's Architectural Genome expressed all six of these as first-class primitives.
The compiler enforced the two-flow contract and generated the Rust code.
The founder built the V1 in 4 hours.
