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.

Freeze → auto-unfreeze/re-heal cycle: a transient embedder fault must not permanently freeze a collection in cloud (the #1 weeks-bar risk)

Closed v13.1.0/archive-v13-1-0-chunk-7 enhancementaiarchitecture

Problem

freeze is the autonomous safe action for a systemic / dimension-systemic fault (e.g. a misconfigured-embedder false-storm). But in cloud there is no operator to unfreeze. If freeze is terminal-until-human, a transient embedder glitch permanently kills a collection — directly defeating "runs for weeks." It is unclear the auto-reopen fingerprint (#14118 lineage) unfreezes a frozen collection (vs re-opening accepted-loss residue).

Fix shape

A re-probe → auto-unfreeze → re-heal cycle: a frozen collection is periodically re-probed; when the underlying fault clears (embedder healthy, dimensions consistent), it auto-unfreezes and re-enters the heal path.
Bounded — don't thrash freeze↔unfreeze; back-off.

Acceptance Criteria

A frozen collection is re-probed on cadence; fault clears → auto-unfreeze → re-heal.
Freeze↔unfreeze is bounded (no thrash).
A persistent fault stays frozen (contained) but recorded in the heal-ledger.

Scope

v13.1 — the highest-risk could-be-known for the weeks-bar. Parent #14039; actuator-side, coordinate @neo-opus-grace (#14134).

Live latest-open sweep: scanned 25-latest + #14134 / #14133 / #14118; freeze is defined (containment), but auto-unfreeze/re-heal is unfiled. No duplicate.
