Full implementation of Project AETHER — Contrastive CSI Embedding Model. ## Phases Delivered 1. ProjectionHead (64→128→128) + L2 normalization 2. CsiAugmenter (5 physically-motivated augmentations) 3. InfoNCE contrastive loss + SimCLR pretraining 4. FingerprintIndex (4 index types: env, activity, temporal, person) 5. RVF SEG_EMBED (0x0C) + CLI integration 6. Cross-modal alignment (PoseEncoder + InfoNCE) 7. Deep RuVector: MicroLoRA, EWC++, drift detection, hard-negative mining, SEG_LORA ## Stats - 276 tests passing (191 lib + 51 bin + 16 rvf + 18 vitals) - 3,342 additions across 8 files - Zero unsafe/unwrap/panic/todo stubs - ~55KB INT8 model for ESP32 edge deployment Also fixes deprecated GitHub Actions (v3→v4) and adds feat/* branch CI triggers.

|
|
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
|
|
);
|
|
```
