Releases: AxonOS-BCI/neural-boundary-game
Neural Boundary Game v8.2.1 — Elite Foundation Grande AxonOS Standard
Neural Boundary Game v8.0.1 — Elite Foundation Grande AxonOS Standard
Neural Boundary Game is an interactive AxonOS simulation focused on neural permissions, consent enforcement, privacy boundaries, evidence-based trust, raw signal exposure, cognitive sovereignty, and operational protection of cognitive data.
This release is the current canonical public build. The chronology below is intentionally ordered in descending version order: from the current v8.0.1 release down to the original v0.1.0 prototype lineage.
Total documented release milestones in this chronology: 77.
Strategic Purpose
Neural Boundary Game is a playable demonstration of the AxonOS thesis:
- neural data requires explicit boundaries;
- cognitive privacy must be enforceable at runtime;
- consent must be operational, not decorative;
- raw neural signal exposure is a critical failure condition;
- trust must be built through verifiable evidence;
- privacy boundaries must be visible, auditable, and recoverable.

Summary
Neural Boundary Game v7.9.812 is a deterministic Rust/WASM browser game and educational simulation for neural privacy boundary scenarios.
Runtime
- Rust/WASM core
- ABI v3
- Packed product version: 0x070900
- Replay schema: neural-boundary-replay-v3
- No telemetry
- No accounts
- No real neural data
- No medical-device claim

- This release is not a medical device, not clinical software, and not stimulation-control software.
AxonOS Boundary Console v7.3.0 RC1
AxonOS Boundary Console v7.3.0 RC1
Public release candidate for the AxonOS Boundary Console.
Positioning
A deterministic Rust/WASM cognitive sovereignty runtime for neural privacy boundaries.
This is the public release-candidate surface formerly developed as Neural Boundary Game. It demonstrates AxonOS boundary principles: raw signal remains private, applications receive typed intent only, and every boundary decision remains deterministic and replayable.
Highlights
- deterministic cognitive sovereignty engine
- flat WASM ABI v3 with 83 exports
- 16 canonical replay vectors
- CLI conformance toolkit
- Grande Style Elite web console
- PWA/fail-closed fallback surface
- EVIDENCE_REPORT.md and SOURCE_MANIFEST.sha256 generated
- 37 Foundation Gates in GitHub Actions
Verification status
- 50 Rust tests
- clippy --workspace --all-targets -D warnings clean
- verify-all 16/16
- ABI v3: 83 exports
- health 0x070300 = 459520
Status
Public release candidate. Not a medical device, not a clinical system, not a hardware stimulation controller.
