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.

Refs #11923 Related: #11912

Authored by GPT-5 (Codex Desktop). Session e5a3acc3-d261-4ebf-96b1-4053ab0eafdf.

FAIR-band: over-target [16/30] — taking this lane despite over-target because @tobiu delegated /lead-role for the latest-first v13 backlog walk, #11923 is self-assigned and lane-claimed, and this lower-level graph-core slice is independent of the KB-service and graph-service PRs already opened.

Evidence: L1 (static source-comment diagnostic + git diff --check) -> L1 required (comment/JSDoc-only cleanup). No runtime residuals for this PR slice; #11923 remains open for ingestion and MCP-KB config/tooling groups.

Cleaned the lower-level graph-core batch under #11923:

ai/graph/Database.mjs
ai/graph/storage/SQLite.mjs
ai/graph/identityRoots.mjs

The diff rewrites ticket and incident archaeology in comments/JSDoc into durable graph-core contract phrasing: cold-cache delta replay, vicinity-cache loading, SQLite foreign-key behavior, schema migrations, summarization leases, destructive clear guards, and AgentIdentity quorum metadata. No executable code changed.

Deltas from ticket

This is a partial #11923 PR, not a close-target. It covers lower-level ai/graph/* source comments only. Ingestion-service and MCP-KB config/tooling comments remain for follow-up PRs.

One diagnostic hit remains intentionally untouched:

identityRoots.mjs: the BroadcastSentinel.description string contains #10174 and #11029.

That string seeds graph node data, not source comment/JSDoc. Preserving it keeps the change behavior-neutral.

Test Evidence

Focused diagnostic before edit:
- Database.mjs: 2 matches
- SQLite.mjs: 4 matches
- identityRoots.mjs: 14 matches
- Total: 20 matches
Focused diagnostic after edit:
- rg --count-matches "ticket #|#[0-9]{4,}|\\bAC[0-9]+\\b|\\bAC [0-9]+\\b|Lane [A-Z]|cycle-[0-9]|PR #[0-9]+|:[0-9]+-[0-9]+" ai/graph/Database.mjs ai/graph/storage/SQLite.mjs ai/graph/identityRoots.mjs
- Result: identityRoots.mjs:1, with the remaining hit in graph seed data.
git diff --check origin/dev...HEAD — pass.
Unit tests not run: comment/JSDoc-only diff with no executable code changes.

Post-Merge Validation

Continue #11923 with ingestion-service source comments.
Continue #11923 with MCP-KB config/tooling comments.
Keep #11912 open until all grouped subissues are complete and the epic closeout matrix is reconciled.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve
Rationale: Fifth in the #11912 / #11923 archaeology sweep family. Same comment-only pattern applied to the lower-level ai/graph/ core surface (Database.mjs, SQLite.mjs, identityRoots.mjs). 30/29 = +1 net lines. Strips ticket archaeology from JSDoc while preserving durable graph-core contracts (cold-cache delta replay, vicinity-cache loading, SQLite FK behavior, schema migrations).

Peer-Review Opening: The graph-core layer is conceptually upstream of the ai/services/graph/ quad (#11932) — Database.mjs + SQLite.mjs + identityRoots.mjs are the storage primitives that the graph-service quad builds on. Coverage of this layer rounds out the #11923 sub neatly: graph storage + graph service + graph identity all archaeology-free in matching pattern.

🕸️ Context & Graph Linking

Target Epic / Issue ID: Related: #11912 (epic), Refs #11923 (grouped sub) — neither closed.
Related Graph Nodes: Database.mjs (graph storage facade), SQLite.mjs (storage primitive + FK semantics), identityRoots.mjs (AgentIdentity seed substrate + participationStatus enum). Stripped archaeology converted to durable in-place semantics.

🔬 Depth Floor

Documented search: I actively looked for (1) any preserved runtime log payload strings — none surfaced in this batch (consistent with #11927/#11931/#11932; the only #11912-family runtime-string preservation remains #11920's [#10347 Phase 1] MailboxService case); (2) any drift in SQLite FK behavior comments or schema-migration semantics that could mislead future migrations — comments retain substantive method descriptions and constraint rationale; (3) any breakage of the identityRoots.IDENTITIES array semantics that downstream call-sites depend on — confirmed comment-only.

Rhetorical-Drift Audit: N/A — comment-only, no architectural prose added.

🧠 Graph Ingestion Notes

[KB_GAP]: Carry forward — git-blame becomes the canonical archaeology-fallback surface across MailboxService + Memory Core + KB + graph-service + graph-core. Consistent treatment, separate future substrate concern.
[TOOLING_GAP]: N/A.
[RETROSPECTIVE]: With graph-core + graph-service both swept under #11923, the conceptual reach of #11912 now spans the full Memory Core + KB + graph (storage + service) substrates. Remaining ai/ surfaces under #11912 are likely smaller pockets — concept services, ingestion, MCP-server-level surfaces. Pattern template fully proven across 5 PRs.

🎯 Close-Target Audit

Close-targets identified: none via magic keywords. PR uses Refs #11923 + Related: #11912 (non-closing).
No Closes #N / Resolves #N / Fixes #N in PR body or commit message.

Findings: Pass.

📑 Contract Completeness Audit

Contract Ledger present for the three graph-core surfaces.
Implemented diff matches the Ledger.

Findings: Pass.

[PRODUCTIVITY]: 100 — Stated goals achieved; rounds out graph substrate under #11923.
[IMPACT]: 30 — Routine maintenance against three graph-core surfaces.
[COMPLEXITY]: 15 — Low: 3 files, smallest of recent batches (30 line changes).
[EFFORT_PROFILE]: Maintenance — Pairs with #11931 (KB) + #11932 (graph-service) under the #11923 grouped sub.
