🚀 RamShared v0.11.0 — Multi-Tier Resilience Hardening, 15 Workspace Crates & 3D Hardware Visuals

🌟 Key Highlights & Architectural Milestones

1. Multi-Tier Memory Cascade Hardening & Tier 3 Qualification

  • 3-Tier Cascade Architecture: Hardened automatic spillway routing across Tier 0 (ZRAM compressed RAM), Tier 1 (GPU VRAM over PCIe Direct DMA), and Tier 3 (Durable Host SSD Origin).
  • Empirical Saturation Stress: Sustained 19,777 MB total allocation under extreme memory pressure (4,096 MB VRAM, 1,024 MB ZRAM, and 2,367 MB active SSD swap) with 100% PASS_ZERO_PANIC and zero kernel lockups.
  • Throughput & Latency: Verified sustained reclaim throughput of 6.07 GiB/s over PCIe Gen3 DMA and ultra-low VRAM page-in latency of 1.72 µs (versus 48.2 µs on SSD).
  • Closed-Loop Swap Governor: Deterministic swap-paced memory consumption governor in stress.rs pacing allocations against active kswapd drain rates.
  • Real-Time Throughput Telemetry: Filtered /proc/diskstats active workload telemetry (>=5.0 MB/s filter) showing empirical tier throughput and speedup factors (30.6x speedup over SSD).
  • Resilient Failover & Auto Backend: In-process RAM fallback buffer hot-swapping from VRAM to RAM on GPU/CUDA failures with zero I/O loss.
  • Volume Lock Isolation (ADR-0010): Implemented RAII LockedVolume guard preventing volume handle contention during driver lifecycle transitions on Windows.
  • Typed Error Propagation (ADR-0009): Eliminated unwrap() and expect() panics across agent and winsvc crates in favor of domain-specific typed error enums.

2. Workspace Topology & Crates Standardization (15 Crates)

  • Authoritative 15-Crate Topology: Formalized ARCHITECTURE.md spanning 6 architectural layers:
    • Frontend & Control: ramshared-cli
    • Daemons & Agents: ramshared-agent, ramshared-wsl2d, ramshared-winsvc
    • Broker & Policy: ramshared-broker, ramshared-winbroker
    • Memory & IO Engines: ramshared-tier, ramshared-vram, ramshared-cuda, ramshared-vulkan, ramshared-dxg, ramshared-uring
    • Storage & Origin: ramshared-block, ramshared-integrity
    • Configuration: ramshared-config
  • Crate Documentation: Authored and deployed standardized README.md documentation for all 15 crates detailing scope, safety invariants, and test coverage.

3. High-Resolution Photoreal 3D Hardware Visuals

  • Self-Contained Hybrid SVGs: Deployed infinite-resolution architecture diagrams (cascade-diagram.svg and cascade-diagram-pt.svg) embedding 1080p photorealistic 3D hardware renders with scalable vector HUD overlays.
  • GitHub Camo & CSP Compliance: Embedded base64 data URIs ensure zero external network calls, rendering crisply on dark and light GitHub themes without Content Security Policy restrictions.

4. Automated Documentation Governance & Multi-Distro Distribution

  • Multi-Distro Packaging: Automated package generation for Debian/Ubuntu (.deb), Fedora/RHEL (.rpm), and Arch Linux AUR (.tar.gz) with SHA-256 verification manifests.
  • Repository Boundary Gate: Automated isolation checks in check-doc-staleness-and-redundancy.mjs preventing private host path leaks and cross-contamination.
  • Automated Drift Checker: Integrated tools/ci/check-doc-code-drift.mjs ensuring workspace crates and driver boundaries never drift from architecture specifications.
  • 35/35 Local Documentation Gates PASS: 100% compliance across all automated governance tests in ./scripts/docs-check.sh.
