ruv df95360e52 feat(adr-110 P10): apply_to_local + NodeState::mesh_aligned_us + full ADR rewrite
Iter 16 closes the math loop and updates ADR-110 to reflect the full
P1-P10 sprint outcome (per user request).

Code (the math layer that converts the iter 15 stored sync into a
per-frame mesh-aligned timestamp):

  wifi-densepose-hardware:
    SyncPacket::apply_to_local(local_at_frame_us: u64) -> u64
      Pure integer math: offset = epoch - local; mesh = local_at_frame + offset.
      3 new unit tests (10 total, all green):
      - apply_to_local_recovers_packet_epoch (identity at the packet's local_us)
      - apply_to_local_preserves_inter_frame_delta (Δlocal == Δmesh)
      - apply_to_local_on_leader_is_near_identity (leader offset ≈ 0)

  wifi-densepose-sensing-server:
    NodeState::mesh_aligned_us(local_at_frame_us: u64) -> Option<u64>
      Returns the recovered mesh timestamp using the most-recent sync
      packet, or None if no sync seen or last one older than 9 s
      (3× firmware VALID_WINDOW_MS = 9 s staleness gate).
      cargo check -p wifi-densepose-sensing-server --no-default-features
        → green

ADR-110 substantial rewrite (per user "update adr 110 with details"):

  - Status line: P1-P10 complete, firmware-side substrate closed at v0.7.0.
  - Front matter now lists all 4 firmware releases + witness link.
  - Phase table grows a P10 row capturing the v0.6.8 / v0.6.9 / v0.7.0
    arc (EMA smoother + sync packet + bit-4 wire-fix + host crates).
  - New §4.1 — /loop 5m SOTA sprint summary table (iters 1-16, 4 releases,
    17 commits, 13 unit tests, what shipped each iter).
  - New §4.2 — measured numbers table with 99.56% RX, 104.1 µs smoothed
    stdev, 3.95x suppression, 1.4 ppm crystal skew, etc — every cell
    backed by a witness §A0.x entry and a preserved bench log.
  - New §4.3 — host-side production surface listing (sync_packet.rs +
    sensing-server NodeState + Python parser, with file paths).
  - §5 open question on 802.15.4 channel resolved (Kconfig, default ch26
    not ch15, with the witness §D1 rationale).
  - New §6 — explicit scope of what's outside this ADR (multistatic fusion
    math in ADR-029/030, hardware-gated measurements needing INA / 11ax AP,
    IDF upstream fixes pending).

Architecture Decision Records

This folder contains 44 Architecture Decision Records (ADRs) that document every significant technical choice in the RuView / WiFi-DensePose project.

Why ADRs?

Building a system that turns WiFi signals into human pose estimation involves hundreds of non-obvious decisions: which signal processing algorithms to use, how to bridge ESP32 firmware to a Rust pipeline, whether to run inference on-device or on a server, how to handle multi-person separation with limited subcarriers.

ADRs capture the context, options considered, decision made, and consequences for each of these choices. They serve three purposes:

  1. Institutional memory — Six months from now, anyone (human or AI) can read why we chose IIR bandpass filters over FIR for vital sign extraction, not just see the code.

  2. AI-assisted development — When an AI agent works on this codebase, ADRs give it the constraints and rationale it needs to make changes that align with the existing architecture. Without them, AI-generated code tends to drift — reinventing patterns that already exist, contradicting earlier decisions, or optimizing for the wrong tradeoffs.

  3. Review checkpoints — Each ADR is a reviewable artifact. When a proposed change touches the architecture, the ADR forces the author to articulate tradeoffs before writing code, not after.

ADRs and Domain-Driven Design

The project uses Domain-Driven Design (DDD) to organize code into bounded contexts — each with its own language, types, and responsibilities. ADRs and DDD work together:

  • ADRs define boundaries: ADR-029 (RuvSense) established multistatic sensing as a separate bounded context from single-node CSI. ADR-042 (CHCI) defined a new aggregate root for coherent channel imaging.
  • DDD models define the language: The RuvSense domain model defines terms like "coherence gate", "dwell time", and "TDM slot" that ADRs reference precisely.
  • Together they prevent drift: An AI agent reading ADR-039 knows that edge processing tiers are configured via NVS keys, not compile-time flags — because the ADR says so. The DDD model tells it which aggregate owns that configuration.

How ADRs are structured

Each ADR follows a consistent format:

  • Context — What problem or gap prompted this decision
  • Decision — What we chose to do and how
  • Consequences — What improved, what got harder, and what risks remain
  • References — Related ADRs, papers, and code paths

Statuses: Proposed (under discussion), Accepted (approved and/or implemented), Superseded (replaced by a later ADR).
