chore: remove empty stub crates wifi-densepose-{api,db,config} (closes #578) (#608)

Each of these crates was a single-line doc-comment placeholder:

  v2/crates/wifi-densepose-api/src/lib.rs:    //! WiFi-DensePose REST API (stub)
  v2/crates/wifi-densepose-db/src/lib.rs:     //! WiFi-DensePose database layer (stub)
  v2/crates/wifi-densepose-config/src/lib.rs: //! WiFi-DensePose configuration (stub)

with empty [dependencies] in their Cargo.toml and zero references from any
source file or Cargo.toml in the workspace (verified by `grep -rln
wifi-densepose-api/-db/-config` across `v2/`). They were reserved early for
an envisioned REST/database/config split that never materialised.

The functionality these would have provided is covered today by:
- REST/WS:  wifi-densepose-sensing-server (Axum)
- Config:   per-crate config + CLI args in sensing-server and desktop
- DB:       no persistent state; system is real-time

Removal prevents `cargo` from listing dead crates, shipping empty published
artifacts to crates.io, or wasting reviewer attention. If any of these names
is needed in the future, reintroduce them with a real implementation.

Per the issue reporter (@bannned-bit / Matad0r) #578 explicitly listed
"OR be removed from workspace members until implementation starts" as an
acceptable resolution.

Updated:
- `v2/Cargo.toml`: drop the three members (with inline comment explaining why)
- `v2/Cargo.lock`: regenerated by cargo check
- `CLAUDE.md`: drop the three rows from the crate table and the publishing
  order list
- `CHANGELOG.md`: add an `[Unreleased] / Removed` entry

Verified:
- `cd v2 && cargo check --workspace --no-default-features` -> finished
  in 48s, no errors (warnings unchanged)

## [Unreleased]
### Removed
- **Stub crates `wifi-densepose-api`, `wifi-densepose-db`, `wifi-densepose-config`** (closes #578).
Each was a single-line doc-comment placeholder with an empty `[dependencies]`
section and zero references from any source file or `Cargo.toml`. The names
were reserved early for an envisioned REST/database/config split that never
materialised; the functionality they would provide is covered today by
`wifi-densepose-sensing-server` (Axum REST/WS), per-crate config + CLI args,
and the project's real-time-only (no-persistent-state) posture. Removing them
from the workspace prevents `cargo` from listing dead crates and shipping
empty published artifacts. If any of these names is needed in the future,
they can be reintroduced with a real implementation.
### Added
- **Real-time CSI introspection / low-latency tap on `wifi-densepose-sensing-server` (ADR-099).**
New `wifi_densepose_sensing_server::introspection` module wires

# wifi-densepose-api
[![Crates.io](https://img.shields.io/crates/v/wifi-densepose-api.svg)](https://crates.io/crates/wifi-densepose-api)

REST and WebSocket API layer for the WiFi-DensePose pose estimation system.
## Overview
`wifi-densepose-api` provides the HTTP service boundary for WiFi-DensePose. Built on
[axum](https://github.com/tokio-rs/axum), it exposes REST endpoints for pose queries, CSI frame
ingestion, and model management, plus a WebSocket feed for real-time pose streaming to frontend
clients.
> **Status:** This crate is currently a stub. The intended API surface is documented below.
## Planned Features
- **REST endpoints** -- CRUD for scan zones, pose queries, model configuration, and health checks.
- **WebSocket streaming** -- Real-time pose estimate broadcasts with per-client subscription filters.
- **Authentication** -- Token-based auth middleware via `tower` layers.
- **Rate limiting** -- Configurable per-route limits to protect hardware-constrained deployments.
- **OpenAPI spec** -- Auto-generated documentation via `utoipa`.
- **CORS** -- Configurable cross-origin support for browser-based dashboards.
- **Graceful shutdown** -- Clean connection draining on SIGTERM.
## Quick Start
```rust
// Intended usage (not yet implemented)
use wifi_densepose_api::Server;
#[tokio::main]
async fn main() -> anyhow::Result<()> {
let server = Server::builder()
.bind("0.0.0.0:3000")
.with_websocket("/ws/poses")
.build()
.await?;
server.run().await
}
```
## Planned Endpoints
| Method | Path | Description |
|--------|------|-------------|
| `GET` | `/api/v1/health` | Liveness and readiness probes |
| `GET` | `/api/v1/poses` | Latest pose estimates |
| `POST` | `/api/v1/csi` | Ingest raw CSI frames |
| `GET` | `/api/v1/zones` | List scan zones |
| `POST` | `/api/v1/zones` | Create a scan zone |
| `WS` | `/ws/poses` | Real-time pose stream |
| `WS` | `/ws/vitals` | Real-time vital sign stream |

Configuration management for the WiFi-DensePose pose estimation system.
## Overview
`wifi-densepose-config` provides a unified configuration layer that merges values from environment
variables, TOML/YAML files, and CLI overrides into strongly-typed Rust structs. Built on the
[config](https://docs.rs/config), [dotenvy](https://docs.rs/dotenvy), and
[envy](https://docs.rs/envy) ecosystem from the workspace.
> **Status:** This crate is currently a stub. The intended API surface is documented below.
## Planned Features
- **Multi-source loading** -- Merge configuration from `.env`, TOML files, YAML files, and
environment variables with well-defined precedence.
- **Typed configuration** -- Strongly-typed structs for server, signal processing, neural network,
hardware, and database settings.
- **Validation** -- Schema validation with human-readable error messages on startup.
- **Hot reload** -- Watch configuration files for changes and notify dependent services.
- **Profile support** -- Named profiles (`development`, `production`, `testing`) with per-profile
overrides.
- **Secret filtering** -- Redact sensitive values (API keys, database passwords) in logs and debug
output.
## Quick Start
```rust
// Intended usage (not yet implemented)
use wifi_densepose_config::AppConfig;
fn main() -> anyhow::Result<()> {
// Loads from env, config.toml, and CLI overrides
let config = AppConfig::load()?;
println!("Server bind: {}", config.server.bind_address);
println!("CSI sample rate: {} Hz", config.signal.sample_rate);
println!("Model path: {}", config.nn.model_path.display());
Ok(())
}
```
## Planned Configuration Structure
```toml
# config.toml
[server]
bind_address = "0.0.0.0:3000"
websocket_path = "/ws/poses"
[signal]
sample_rate = 100
subcarrier_count = 56

# wifi-densepose-db
[![Crates.io](https://img.shields.io/crates/v/wifi-densepose-db.svg)](https://crates.io/crates/wifi-densepose-db)
[![Documentation](https://docs.rs/wifi-densepose-db/badge.svg)](https://docs.rs/wifi-densepose-db)
[![License](https://img.shields.io/crates/l/wifi-densepose-db.svg)](LICENSE)
Database persistence layer for the WiFi-DensePose pose estimation system.
## Overview
`wifi-densepose-db` implements the `DataStore` trait defined in `wifi-densepose-core`, providing
persistent storage for CSI frames, pose estimates, scan sessions, and alert history. The intended
backends are [SQLx](https://docs.rs/sqlx) for relational storage (PostgreSQL and SQLite) and
[Redis](https://docs.rs/redis) for real-time caching and pub/sub.
> **Status:** This crate is currently a stub. The intended API surface is documented below.
## Planned Features
- **Dual backend** -- PostgreSQL for production deployments, SQLite for single-node and embedded
use. Selectable at compile time via feature flags.
- **Redis caching** -- Connection-pooled Redis for low-latency pose estimate lookups, session
state, and pub/sub event distribution.
- **Migrations** -- Embedded SQL migrations managed by SQLx, applied automatically on startup.
- **Repository pattern** -- Typed repository structs (`PoseRepository`, `SessionRepository`,
`AlertRepository`) implementing the core `DataStore` trait.
- **Connection pooling** -- Configurable pool sizes via `sqlx::PgPool` / `sqlx::SqlitePool`.
- **Transaction support** -- Scoped transactions for multi-table writes (e.g., survivor detection
plus alert creation).
- **Time-series optimisation** -- Partitioned tables and retention policies for high-frequency CSI
frame storage.
### Planned feature flags
| Flag | Default | Description |
|------------|---------|-------------|
| `postgres` | no | Enable PostgreSQL backend |
| `sqlite` | yes | Enable SQLite backend |
| `redis` | no | Enable Redis caching layer |
## Quick Start
```rust
// Intended usage (not yet implemented)
use wifi_densepose_db::{Database, PoseRepository};
use wifi_densepose_core::PoseEstimate;
#[tokio::main]
async fn main() -> anyhow::Result<()> {
let db = Database::connect("sqlite://data/wifi-densepose.db").await?;
db.run_migrations().await?;
let repo = PoseRepository::new(db.pool());
// Store a pose estimate
repo.insert(&pose_estimate).await?;
// Query recent poses
let recent = repo.find_recent(10).await?;
println!("Last 10 poses: {:?}", recent);
Ok(())
}
```
## Planned Schema
```sql
-- Core tables
CREATE TABLE csi_frames (
id UUID PRIMARY KEY,
session_id UUID NOT NULL,
timestamp TIMESTAMPTZ NOT NULL,
subcarriers BYTEA NOT NULL,
antenna_id INTEGER NOT NULL
);
CREATE TABLE pose_estimates (
id UUID PRIMARY KEY,
frame_id UUID REFERENCES csi_frames(id),
timestamp TIMESTAMPTZ NOT NULL,
keypoints JSONB NOT NULL,
confidence REAL NOT NULL
);
CREATE TABLE scan_sessions (
id UUID PRIMARY KEY,
started_at TIMESTAMPTZ NOT NULL,
ended_at TIMESTAMPTZ,
config JSONB NOT NULL
);
