rUv e1f4897269 fix(geo numerical): parse_hgt underflow/inf-grid (HIGH) + haversine asin-NaN; pointcloud confirmed-robust (NaN-poisoning class, 3rd find) (#1081)
* fix(geo numerical robustness): parse_hgt underflow panic + haversine asin-domain NaN

Targeted numerical-robustness audit of wifi-densepose-geo (ADR-154-class sweep).

Two real bugs, each pinned by a fails-on-old test:

1. terrain.rs parse_hgt — usize underflow panic on degenerate input.
   `side = sqrt(n_samples)`; for empty / sub-2x2 buffers side <= 1, so
   `1.0 / (side - 1)` underflows `usize` (panic "attempt to subtract with
   overflow" in debug; wraps to a huge value in release → garbage/inf
   cell_size_deg that poisons every ElevationGrid::get). A truncated HTTP
   body or a 404 HTML page reaches parse_hgt. Now bails with a clear error
   when side < 2.

2. coord.rs haversine — asin domain overflow → NaN for (near-)antipodal
   points. Floating rounding can push `h.sqrt()` to 1.0 + ~4e-16, and
   `asin(>1)` is NaN (verified: pair (-44.4994,-178.95722)→(44.49939999,
   1.04278001) yields h=1.0000000000000004). A NaN distance silently breaks
   all downstream `<`/`>` comparisons. Clamp into [0,1] before asin.

Also pins the ±90° pole-singularity (cos(lat)=0 division) as no-panic; the
ENU transform itself is unchanged (no behavior change for valid inputs).

Tests: wifi-densepose-geo 9→15 lib (6 new), 8 integration unchanged. 0 failed.

* test(pointcloud robustness): pin NaN-state-poisoning resistance + degenerate voxel fusion

Numerical-robustness audit of wifi-densepose-pointcloud. No bug found — the
crate is confirmed-robust against the proven NaN-state-poisoning class that bit
calibration/vitals. This adds regression pins documenting why:

1. csi_pipeline.rs — persistent auto-accumulating state (occupancy EMA,
   vitals) is provably self-healing. The UDP parser only emits finite
   amplitudes/phases (sqrt/atan2 of i8), and even an adversarial hand-built
   CsiFrame with NaN/inf amplitudes+phases cannot latch non-finite state:
   motion_score = (NaN/100).min(1.0) → 1.0; breathing path → 0 → clamp(5,40)
   → 5.0; tomography EMA uses only integer rssi. The new test injects 40
   poisoned frames and asserts occupancy/vitals stay finite AND the pipeline
   recovers to an in-range estimate afterward — so a future refactor that drops
   a `.min`/`.clamp` self-heal would fail this pin.

2. fusion.rs — fuse_clouds voxel averaging is div-by-zero-safe (per-voxel
   count >= 1 by construction). Pins empty / single-point / all-coincident
   inputs as no-panic with finite output.

No behavior change. Tests: wifi-densepose-pointcloud 18→22 (4 new), 0 failed.

* docs(geo/pointcloud robustness): CHANGELOG + ADR-154 sibling-crate sweep note

Record the wifi-densepose-geo + wifi-densepose-pointcloud numerical-robustness
audit under CHANGELOG [Unreleased] → Fixed, and a sibling-crate-extension note
on the ADR-154 horizon ledger (these crates are outside ADR-154's signal scope
but the sweep is the same ADR-154 class).

Architecture Decision Records

This folder contains 45 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).
