Release: RuVix Cognition Kernel — ADR-087 & Implementation Plan

[ruvnet]

Overview

ADR-087 defines RuVix — a cognition kernel for the Agentic Age built on RuVector and RVF primitives. This issue tracks the release of the architecture document and subsequent implementation.

PR: #248
ADR: ADR-087-ruvix-cognition-kernel.md

What RuVix Is

A minimal cognition kernel with 6 primitives (task, capability, region, queue, timer, proof) and 12 syscalls. Not a Linux clone — a purpose-built OS for agentic workloads where:

• RVF is the boot object — signed packages are complete cognitive units
• RuVector is kernel-resident — vectors and graphs are native kernel resources, not userspace databases
• Every mutation is proof-gated — kernel invariant, not library convention
• Scheduling is coherence-aware — deadline + novelty signal + structural risk
• No POSIX — WIT/RVF contracts replace files, processes, and pipes

Syscall Surface (12 total)

task_spawn, cap_grant, region_map, queue_send, queue_recv, timer_wait,
rvf_mount, attest_emit, vector_get, vector_put_proved, graph_apply_proved,
sensor_subscribe

Build Path

Phase A: Linux-Hosted Nucleus (Days 1-60)

Crate	Purpose	Weeks
ruvix-types	Kernel types (no_std, no alloc)	1-2
ruvix-region	Slab/append-only/immutable regions	3-4
ruvix-queue	io_uring-style ring buffer IPC	5-6
ruvix-cap	Capability table + derivation tree	7-8
ruvix-proof	Proof token generation/verification	9-10
ruvix-vecgraph	Kernel vector/graph stores	11-12
ruvix-sched	Coherence-aware scheduler	13-14
ruvix-boot	RVF boot loader	15-16
ruvix-nucleus	Integration + ABI freeze	17-18

Phase B: Bare Metal AArch64 (Days 60-120)

• AArch64 bootstrap (exception vectors, MMU, UART)
• Region → physical memory mapping
• GIC interrupt → queue delivery
• WASM component runtime on bare metal
• Hardware scheduler with timer preemption

Acceptance Test

A signed RVF boots, consumes a RuView event, performs one proof-gated vector mutation, emits an attestation, and replays to the same state after restart.

Release Published ✅

Release: v0.88.0
PRs merged: #244 (Neural Trader WASM) + #248 (RuVix Kernel ADR)

Verification

• All 22 Rust tests passing
• 43 Node.js integration tests passing
• Zero clippy warnings on neural-trader crates
• All CI checks green (clippy, feature checks, wasm dedup, 5 cross-platform builds)
• Security review: ADR-087 architecture is clean — no hardcoded secrets, capability model has no escalation paths, proof-gated mutation has no bypass vectors

Next Steps

Phase A implementation begins — first deliverable: ruvix-types crate (no_std, no alloc).
