jev-layer v0.1.0

Initial public release of a portable System-1 decision layer for agent harnesses.

Highlights

Closed-set capability routing through jev_route.
Stdio MCP and CLI interfaces.
Host-owned execution, permissions, approvals, retries, and recovery.
jev_record_execution receipts joined by correlation_id.
Offline replay and evaluation without host execution.
Optional supervision and deterministic context filtering.
Hermes, OMP, Codex, and generic MCP integration examples.
Experimental browser fast-path over host-supplied observations.
MIT licensing, contribution guide, security policy, schema policy, CI, and multilingual documentation.

Node.js 20 or newer.
Schema v1 preserved for routing, MCP tools, receipts, replay cases, and adapters.
Release-preparation baseline: OMP 18.2.6, Hermes 0.21.3 (b675e6de), Codex CLI 0.155.1.

Host harnesses remain the source of truth for permissions and execution.
Browser reliability is validated against current real-browser fixtures.
Browser performance optimization remains experimental.
No browser speedup claim is made.
Provider-backed tests require explicitly configured secret-managed environments.
