rUv 67fec45e61 feat(edge-registry): ADR-102 — surface Cognitum cog catalog via /api/v1/edge/registry (#648)
* feat(edge-registry): ADR-102 — surface Cognitum cog catalog via /api/v1/edge/registry

Adds a new sensing-server endpoint that fetches and caches the canonical
Cognitum app registry at
https://storage.googleapis.com/cognitum-apps/app-registry.json (105 cogs
across 11 categories as of v2.1.0). RuView previously had no live
awareness of the catalog — the README's capability table was hand-
curated and went stale as Cognitum shipped new cogs (the registry was
last updated 6 days ago).

ADR:
* docs/adr/ADR-102-edge-module-registry.md — full design, response
  shape, configuration flags, failure modes, and a 12-row security
  review covering SSRF, response inflation, ?refresh abuse, stale-serve
  semantics, TLS, cache poisoning, JSON-panic resistance, etc.

Code:
* v2/.../edge_registry.rs — EdgeRegistry struct + UreqFetcher +
  MockFetcher trait + 7 unit tests. RwLock<Option<CachedEntry>> with
  stale-on-error fallback. MAX_PAYLOAD_BYTES=8 MiB, 10s wire timeout.
* v2/.../main.rs — constructs Option<Arc<EdgeRegistry>> at startup,
  registers GET /api/v1/edge/registry handler, wires Extension layer.
  Handler runs the blocking ureq fetch via tokio::task::spawn_blocking
  so the async runtime stays free.
* v2/.../cli.rs / main.rs Args — three new flags (per user request to
  "allow the registry to be disabled or changed"):
    --edge-registry-url <URL>       (env RUVIEW_EDGE_REGISTRY_URL)
    --edge-registry-ttl-secs <N>    (env RUVIEW_EDGE_REGISTRY_TTL_SECS)
    --no-edge-registry              (env RUVIEW_NO_EDGE_REGISTRY)
  When --no-edge-registry is set or the URL is empty, the endpoint
  returns 404.

Cargo.toml: adds ureq (rustls), sha2, thiserror as direct deps.

README:
* New collapsed "🧩 Edge Module Catalog" section with the full 105-cog
  table generated from the registry, grouped by category with practical
  one-line descriptions (e.g. "Spots irregular heartbeats and abnormal
  heart rhythms", "Detects walking problems and scores fall risk").
  Links to https://seed.cognitum.one/store and the local appliance
  /cogs page. Sits between the HF model section and How It Works.

Tests (7/7 pass):
  first_call_hits_upstream_and_caches
  ttl_expiry_triggers_refetch
  force_refresh_bypasses_fresh_cache
  stale_serve_on_upstream_failure_after_cached_success
  no_cache_no_upstream_returns_error
  upstream_invalid_json_is_treated_as_error
  upstream_sha256_is_deterministic

Security highlights (full review in ADR-102 §"Security review"):
- The registry is metadata-only; per-cog binary signatures (ADR-100)
  remain the trust root for installs. A compromised registry can
  mislead a human reader but cannot ship malicious binaries.
- 8 MiB cap + 10s timeout + Option<Arc<...>> via Extension layer means
  the endpoint can't be used to exhaust memory or pin tokio threads.
- Stale-on-error responses carry an explicit `stale: true` field so
  upstream outages are visible to consumers rather than silently
  masked.
- Endpoint sits behind the existing RUVIEW_API_TOKEN bearer gate when
  set, otherwise unauthenticated (registry contents are public anyway).

* chore: refresh Cargo.lock for ureq/sha2/thiserror deps added by ADR-102

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).
