Runtime

• POST /v1/events — hardware/software event ingestion with glob-based agent routing (event_types in constitution)
• /parallel concurrency fix — per-child ApiClient instances so parallel agents run without blocking
• Sandbox exec (--sandbox) — Docker-based isolated /exec with configurable image and resource limits
• Idempotency cache — replay-safe request deduplication via Idempotency-Key header
• Circuit breaker — per-provider failure tracking with automatic open/half-open/close transitions
• Metrics — GET /v1/metrics Prometheus-compatible endpoint; request counts, latency histograms, error rates
• Structured logger — replaces scattered fprintf with leveled JSON logging
• /todo writ — agents can create operator todos from writs; PATCH /v1/todos/:id to resolve
• Advisor — GET /v1/advise/gate pre-flight constitutional check before orchestration

Examples

• examples/3bo/ — voice robot reference project: Arduino Nano ESP32 firmware, Jetson bridge, agent constitutions, full hardware docs
• examples/voice-bridge/ — production STT→Arbiter→TTS bridge (whisper.cpp + Piper)
• examples/sandbox/ — Dockerfile and setup script for sandboxed agent exec

Docs

• New: docs/api/events.md, docs/api/metrics.md, docs/api/todos/patch.md, docs/concepts/sandbox.md, docs/concepts/operations.md, docs/cli/environment.md
• Updated: orchestrate, constitution, tenant, A2A, memory, writ, todos, audit docs
• Removed: docs/getting-started/hosted.md

Tests

• New suites: circuit breaker, idempotency cache, logger, metrics, todos, commands
