synos-package-manager — Package management abstraction

Classification: PUBLIC
Crate: fruit/crates/synos-package-manager/
Milestone: v1+

Version: v111.0.0 “Last Light”

What It Is

synos-package-manager is a high-performance, Rust-based package management abstraction for Syn_OS, handling package discovery, dependency resolution, installation, rollback, and security validation. It supports multiple repository sources, GPG signature verification, parallel download/install pipelines, and integrates with the build system for reproducible installs. A consciousness integration module hooks package operations into the broader Syn_OS AI ecosystem.

Architecture

Modules

Module	Purpose
core	Core Package, PackageManager, PackageSource, and PackageStatus types
repository	Repository manager for multi-source package discovery and metadata caching
dependency	Graph-based dependency resolver using petgraph for conflict detection and topological ordering
install	Installation engine with parallel download, extraction, and verification pipelines
rollback	Rollback manager with snapshot-based system state recovery
security	Security validator for GPG signatures, hash verification, and capability whitelisting
cli	Rollback command definitions for the synos-pkg CLI binary
consciousness	Consciousness integration layer reporting package operation metrics to syn-ai
build_integration	Build system hooks for workspace-level feature orchestration and reproducible builds

How It’s Wired

1. syn-ai consciousness — The consciousness module reports PerformanceMetrics (operation duration, memory, cache hit ratio) back to the AI engine, allowing it to optimize repository selection and parallel download counts over time.
2. Security validation — The security module validates package signatures using ring for Ed25519/RSA verification, with SecurityLevel enum (Minimal, Standard, Enhanced, Paranoid) controlling strictness.
3. Database layer — Dual storage: sqlx + SQLite for async metadata queries and rusqlite for synchronous index operations, both using bundled SQLite for portability.
4. Archive support — tar, flate2, and xz2 handle package extraction; blake3 provides fast content hashing for cache keys.

Future Ideas

1. Add a synos-package-manager-sandbox module that installs packages into isolated Bubblewrap/WASM environments for pre-flight validation.
2. Implement delta-patching using xz2 block-level diff to reduce bandwidth for large package updates.
3. Expose a synos-raas-api endpoint for MSSP clients to query package compliance status across managed tenants.
