What is the Neural Link?

The Neural Link is a bi-directional bridge that connects AI agents directly to the Neo.mjs runtime. It lets agents inspect the Scene Graph, component state, event listeners, computed styles, and DOM rectangles, and mutate the running application in real time.

Why is Neo.mjs called an Application Engine instead of a framework?

Neo.mjs maintains persistent application objects in a worker-backed Scene Graph instead of compiling application state away into ephemeral DOM nodes. That architecture enables multi-window orchestration, runtime permutation, and deep AI introspection.

What is Context Engineering?

Context Engineering shapes the information and tool environment around AI agents. Neo.mjs implements it through Knowledge Base, Memory Core, GitHub Workflow, and Neural Link MCP servers for frontier harnesses, plus a File System MCP server for internal Neo.ai.Agent local loops.

What is the Neo.mjs Agent OS?

The Neo.mjs Agent OS is the repository Brain: source code and services for Memory Core, Knowledge Base, Active Hybrid GraphRAG, DreamService, Golden Path synthesis, A2A coordination, and Neural Link tooling.

Expand mailbox test coverage and role-based addressing

Closed v13.0.0/archive-v13-0-0-chunk-5 enhancementaitesting

tobiu commented on Apr 21, 2026, 11:24 PM

Context: Follow up to the Phase 3 Mailbox A2A integration (#10146, #10147). The core primitives were shipped in PR #10167, but test coverage for the expanded API surface and the role-based addressing mode were deferred to unblock Phase 4.

The Problem: Missing test coverage for pagination, outbox mode, advanced filtering, and edge creation leaves the new API surface vulnerable to regressions. Missing role-based addressing leaves the AC of #10147 incomplete.

The Architectural Reality: MailboxService.mjs handles the logic. Needs tests covering listMessages filters and addMessage full schema. Role-based addressing needs routing logic in MailboxService supporting role:<name> and human:<login>.

The Fix:

Add comprehensive tests to MailboxService.spec.mjs for all new features.
Implement role-based addressing parsing and permission evaluation.

Acceptance Criteria:

Outbox mode is tested.
Pagination (limit/offset) boundary behavior is tested.
Thread and sender filtering (threadId, from) are tested.
6 new edge types are verified to be created and queryable.
Reachable Counterparty exception is tested.
listPermissions access-denied path is tested.
role:next-session, role:librarian, human:<login> addressing modes are implemented and tested.

Out of Scope: TAGGED_CONCEPT Gemma4 auto-emit (handled in separate ticket).
