Changelog

[Unreleased] — 2026-03-02

Added

  • VIP / trusted-partner matching is now live. Set LOXI_TRUSTED_PARTNERS to a comma-separated list of node IDs in the orchestrator .env; those nodes get Tier 1 priority in the scheduler. Previously the constant was hardcoded empty and the code path never fired.
  • Rate limiting on POST /logistics/submit-problem: 20 requests per second per IP with a burst allowance of 5, powered by governor 0.6. Requests exceeding the limit receive HTTP 429 with a JSON error body. Read-only routes are unaffected.
  • Parallel auction dispatch: the Logistics Architect now batches all partition auction messages into a single WebSocket flush rather than sending them sequentially, cutting time-to-first-bid for multi-partition jobs.
  • Auction persistence via sled. In-flight auctions survive an orchestrator restart — on startup the node reloads all pending auctions from data/loxi_auctions.db, clears stale worker assignments, and re-queues the tasks. State is updated on every transition (created, assigned, completed/removed).
  • OPFS matrix caching in the browser worker. Before computing a distance matrix, the worker derives a SHA-256 cache key from the stop list and origin, reads from the Origin Private File System on a hit, and writes back on a miss. Identical problems solved twice skip Valhalla entirely.
  • OPFS quota eviction: after each cache write the worker checks storage utilisation; if usage exceeds 80% it deletes the oldest cache files until usage drops to 70%.
  • Multi-city tile support in scripts/download_tiles.sh. Set LOXI_CITIES to a comma-separated list of Geofabrik region slugs (e.g. south-america/argentina-latest,south-america/uruguay-latest) and the script downloads all PBF files and builds a single Valhalla tile tree covering every region.
  • Playwright E2E test harness at tests/e2e/. The smoke test opens two worker tabs, connects both to the grid, dispatches a 10-stop problem, waits for the matrix and VRP steps to complete, and asserts the solution is returned via the API. A new .github/workflows/e2e.yml workflow runs it on every pull request.
  • Docker Compose setup (compose.yml + Dockerfile.node). Running docker compose up --build starts the orchestrator/API server and the worker-web Vite dev server with no manual Rust toolchain installation required.
  • GitHub Actions workflow for publishing the SDK to npm. Pushing a sdk-v* tag triggers a build and npm publish --access public using an NPM_TOKEN repository secret.

Changed

  • SDK package renamed from @loxi/worker-sdk to @loxi/worker-device, aligning the package name with the exported LoxiWorkerDevice class. publishConfig.access is now set to "public" and the files field restricts the tarball to dist/ only.

[Unreleased] — 2026

Added

  • Ticket verification on the WebSocket data plane. The orchestrator now signs a short-lived RS256 JWT for every lease it issues. Workers must present this ticket when connecting to /logistics/data; connections without a valid ticket are rejected before any problem payload is sent.
  • Live worker count endpoint (GET /workers/count) backed by an atomic counter that increments and decrements as nodes connect and disconnect. The worker UI polls this every five seconds and shows the count in the header.
  • CSV and JSON stop upload in the worker UI. You can now load real-world stops from a CSV file (any column layout with lat and lon headers) or paste a JSON array directly into the text area — no need to generate random stops for a demo.
  • Solution export. Once a mission completes, two download buttons appear in the header: CSV (one row per stop with route ID, coordinates, and sequence order) and GeoJSON (a FeatureCollection with LineString routes and Point features for each stop).
  • Solution metrics panel in the Mission Architect section showing total route distance in kilometres, number of vehicles used, and unassigned stop count — computed as soon as the solution arrives.
  • Time-window tooltips on map markers. Hovering a stop now shows its ID and delivery window in HH:MM–HH:MM format.
  • VITE_ARCHITECT_URL environment variable for the worker UI, replacing the hardcoded localhost:8080. An .env.example file documents both configurable URLs.
  • TTL eviction in the orchestrator watchdog. Completed auctions are now purged after one hour, preventing unbounded growth of the in-memory auction map during long-running sessions.

Fixed

  • Duplicate solution submissions no longer overwrite a completed auction. If a worker reconnects after a timeout and submits a result for an auction that already resolved, the duplicate is silently dropped.
  • The Heavy (500-stop) problem generation button now shows a confirmation dialog explaining the hardware and time requirements before dispatching, preventing accidental load during demos.
  • Task failure events now display a "will retry in ~120s" message in the telemetry log, making the orchestrator's recovery behaviour visible to the operator.
  • Removed a debug console.log that ran on every render and logged internal map state to the browser console.

Removed

  • Removed unused crates from the workspace: loxi-compute, loxi-net-core, loxi-net-wasm, and loxi-asset-manager. The workspace is leaner and the remaining crates have no unused dependencies.

[0.1.0] — 2026 — POC

Added

  • Grid Orchestrator with auction-based task dispatch, three-tier affinity matching (artifact cache → hardware score → queue), and a binary-heap scheduler.
  • Task timeout watchdog: workers silent for more than 120 seconds are evicted and their tasks automatically re-queued.
  • RS256 JWT ticket signing for lease assignments.
  • Logistics Architect implementing a three-tier problem pipeline: direct VRP for small problems, geographic partitioning for medium ones, and a full matrix → partitioner → VRP pipeline for large ones.
  • WASM cartridges for the VRP solver (vrp-pragmatic), road-distance matrix engine (Valhalla), and H3 geographic partitioner.
  • React worker UI with live telemetry, Leaflet map with Valhalla polyline rendering, and hardware preset selection.
  • LoxiWorkerDevice TypeScript SDK for embedding a worker in any web application.
  • Signal message type for WebRTC peer-to-peer signaling between workers.
  • Domain ID parametrization — the logistics domain ID is now a runtime parameter rather than a hardcoded string, making the orchestrator reusable across domains.
  • Full POC bootability: rustls-tls for TLS without a system OpenSSL dependency, fixed RSA key parsing from .env files, and scripts/run_node.sh for one-command startup.
