Includes 21 entity kinds per node — 11 raw signals + 10 inferred semantic primitives (HA-MIND: someone-sleeping, possible-distress, room-active, elderly-inactivity-anomaly, meeting, bathroom, fall-risk, bed-exit, no-movement, multi-room-transition). The semantic primitives run server-side so `--privacy-mode` strips HR/BR/pose values from the wire while still publishing the inferred *states* — the architectural win for healthcare and AAL deployments. Ships **8 starter HA Blueprints** under `examples/ha-blueprints/`, **3 drop-in Lovelace dashboards** under `examples/lovelace/` (including a privacy-mode-compatible healthcare care view), mTLS support, 32 KB payload-size cap, MQTT-wildcard topic-injection rejection, `RUVIEW_MQTT_STRICT_TLS=1` v0.8.0 upgrade path. **420 lib tests** cover the implementation including **~2,560 fuzzed assertions per CI run** (10 proptest cases across wire-boundary security + semantic-bus invariants). Plus mosquitto-backed integration tests in `.github/workflows/mqtt-integration.yml`, criterion benchmarks beating every ADR target by 1.6×–208×, and an ESP32-S3 hardware validation harness (`scripts/validate-esp32-mqtt.sh`) that asserts the full pipeline end-to-end with a witness bundle generator (`scripts/witness-adr-115.sh`) that self-verifies.

The format is intentionally extension-friendly — segment types are `u8` enums, new types can land without breaking older readers. + +## 3. The integration surface + +Three concrete touchpoints, each shippable independently. + +### 3.1 RVF as the rvAgent ↔ RuView wire + +rvAgent's `AgiContainer` (`rvagent-core/src/agi_container.rs`, 627 LOC) already produces RVF-compatible blobs as its persistent state format. RuView only needs to define **two segment types** in `rvf_container.rs`: + +- `SEG_AGENT_STATE = 0x08` — serialized `rvagent_core::AgentState` (the cloned-on-write tree from `cow_state.rs`). +- `SEG_DECISION = 0x09` — a single agent decision step: tool calls issued, outputs received, witness signature. + +With these two segments, an rvAgent session and a RuView sensing session can interleave entries in the same RVF blob. The witness-bundle script (ADR-028) iterates segments by type, so it would attest both halves with one signing pass. + +### 3.2 BFLD events as rvAgent tool inputs + +`wifi-densepose-bfld::BfldEvent` (iter 13) is already JSON-serializable via `to_json()`. Wrapping it as an `rvagent_tools::ToolOutput` is a 20-line shim: the agent issues a `read_bfld_state()` tool, the runtime returns the latest event JSON, the agent reasons over it. The full event surface (presence/motion/count/identity_risk/zone_id) becomes available as agent context without any new IPC. + +`BfldEvent → ToolOutput` mapping: +```rust +impl From for ToolOutput { + fn from(e: BfldEvent) -> Self { + ToolOutput::json(e.to_json().expect("BfldEvent JSON")) + } +} +``` + +### 3.3 cog-* as rvAgent subagents + +`cog-pose-estimation`, `cog-person-count`, `cog-ha-matter`, and (proposed) `cog-bfld` already share a packaging convention (ADR-100). Each cog can register as a subagent with rvAgent's hub: the cog implements the `Subagent` trait, exports its tool surface, and inherits the parent agent's CRDT state. The queen agent (`rvagent-queen.md` persona) routes operator queries across the cog mesh. + +Concrete example: +- Operator query: "is grandma awake yet?" +- Queen agent fans out to: `cog-bfld` (presence in bedroom), `cog-quantum-vitals` (HR baseline shift), `cog-pose-estimation` (sitting/standing transition). +- Each cog returns within budget; queen synthesizes the answer; witness chain logs the decision for compliance audit. + +## 4. Open questions + +1. **Workspace inclusion**: is `vendor/ruvector/crates/rvAgent/` already on the v2 workspace path, or does it need to be added as a path dep under `wifi-densepose-bfld` / a new `wifi-densepose-agent` crate? +2. **Async runtime**: rvAgent backends are tokio-based. The BFLD `Publish` trait is intentionally sync (iter 22). A small adapter (sync `Publish` ↔ async `Backend`) probably belongs in a `wifi-densepose-agent` crate, not in BFLD itself. +3. **Privacy class composition**: what's the rvAgent equivalent of BFLD's `PrivacyClass`? `rvagent-middleware::sanitizer` strips at the tool-output boundary; should it consume `PrivacyClass` from the originating BFLD event so the agent never even sees a class-3 identity field? +4. **Soul Signature interaction**: rvAgent's `SoulMatchOracle` integration (ADR-121 §2.6) could be the bridge from the Soul Signature graph (`docs/research/soul/`) to the agent decision layer. Worth a dedicated sub-section. +5. **MCP**: `rvagent-mcp` exposes tools to external MCP clients. Should the BFLD `BfldPipelineHandle::send` surface land as an MCP tool here, or stay private to in-process rvAgent flows? + +## 5. Proposed next steps (decision deferred) + +- **D1**: Open ADR-124 — "rvAgent + RVF integration for RuView agentic flows" — capturing the segment-type assignments, the cog-subagent contract, and the privacy-class composition rule. +- **D2**: Scaffold `v2/crates/wifi-densepose-agent` with the sync ↔ async adapter and one example tool (`read_bfld_state`). +- **D3**: Add `SEG_AGENT_STATE` and `SEG_DECISION` to `rvf_container.rs` as `#[cfg(feature = "agent")]` segments so the v0 ship doesn't pull rvAgent's transitive deps by default. +- **D4**: Land a one-page demo in `examples/agent-bedroom-check/` showing the queen-agent flow end-to-end against the `BfldPipelineHandle`. + +## 6.
