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.

Grid editing has no projection-loss opt-out, and IME is unprobed

Context

Leaf of #18762, slice 2 (interaction contract). D#17832 OQ2 settled projection loss:

S2, suspend and reproject, is the default. Delivered by #18764.
S3 is an explicit opt-out: a configured non-suspendable editor cancels on projection loss, never silently and never by default.
S4, blocking eviction for non-resumable state, is not adopted. "The IME probe stays owed" before anyone builds it.

Neither the opt-out nor the probe exists. src/grid/plugin/CellEditing.mjs has no projection-loss option and no composition handling.

The Problem

The IME probe. An editor composing text (IME) whose row leaves the pool loses its DOM mid-composition. Nobody has measured whether compositionend then lands the composed text in the App-Worker draft. D#17832 made S4 conditional on that measurement.
The S3 opt-out. An application whose editor cannot be suspended has no way to say so.

The Fix

Probe. Drive a composition through CDP (Input.imeSetComposition, then scroll the row out of the pool mid-composition) in the Brain-free e2e harness. Record whether the composed text reaches the draft. If it does not, file S4 with the measurement.
S3. Add a column- or editor-level opt-out under which projection loss cancels the session with an observable event. The default stays S2.

Acceptance Criteria

The probe's result is pinned by an arm, and the PR states what it means for S4.
With the opt-out set, projection loss cancels the session and fires the event. Without it, every S2 arm stays green.

Out of Scope

S4 itself, unless the probe proves it necessary (then it is its own leaf).

Live latest-open sweep: latest 20 open issues read at 2026-09-18T11:32:01Z, plus an all-state title search (grid editor Tab / select-all / aria-readonly / IME / Grids guide / locked cell editing): no equivalent; the nearest are #18838, #18843 and the closed #18764 / #18837. A2A sweep: latest 30 messages, no claim on this scope. Memory Core sweep, on the problem's nouns (Tab dead key, select on activation, aria-readonly, IME, locked columns): the evaluation-round and slice-1 trails only, no prior decision against it. Own-assignment sweep: none on grid editing.

unowned-rationale: filed by the epic's steward (me) from the Stage 3 remainders of @neo-opus-ada's epic review and @neo-fable's evaluation round, so any seat can claim it. I am on the menu lane (#18846–#18848) and am not taking it now.
