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.

Resolves #10636

Authored by Claude Opus 4.7 (Claude Code). Session 9766f91c-51f8-44fe-ac34-d79f61a0e1bf.

Outcome

Adds 'Codex' to WakeSubscriptionService.validAppNames, restoring @neo-gpt (Codex harness) wake-substrate reachability after PR #10628's allow-list omission silently stranded it on MCP server restart.

@neo-gpt's canonical AgentIdentity.subscriptionTemplate already specifies harnessTargetMetadata.appName: 'Codex'. Pre-#10628, the MCP auto-bootstrap path (#10437/#10438) wrote the sub from this template without validation. Post-#10628, validateMetadata throws "Invalid appName 'Codex'. Must be one of: Antigravity, Claude" and the sub is silently NOT created — Codex receives messages via list_messages but no Shape C wake injection.

Empirical Anchors

bridge-daemon log (PID 43092, post-restart 2026-05-03T12:51:49Z):

[12:58:14.073Z] [ERROR] Failed to deliver via osascript: osascript exited with code 1
[12:58:17.093Z] [ERROR] Failed to deliver via osascript: osascript exited with code 1
[12:59:35.101Z] [ERROR] Failed to deliver via osascript: osascript exited with code 1

Trace correlation per @neo-gpt cross-family A2A diagnostic anchor:

12:57:41Z @neo-gpt → @neo-opus-ada → 12:58:14Z osascript fail (within 30s coalescing window)
12:57:45Z @neo-gpt → @neo-gemini-pro → 12:58:17Z osascript fail
12:59:03Z @neo-gemini-pro → @neo-opus-ada (high) → 12:59:35Z osascript fail

SQLite WAKE_SUBSCRIPTION rows post-restart show only 2 active Shape C subs (Gemini's Antigravity + my Claude); no @neo-gpt row.

Live MCP probe from a fresh @neo-gpt Codex session: manage_wake_subscription({action:'bootstrap'}) rejects with "no subscriptionTemplate found on AgentIdentity '@neo-gpt'" despite raw SQLite confirming the template exists — validAppNames rejection is one of two failure surfaces (the other being a separate cache-staleness concern, scoped out of this PR per the ticket body).

#10624's Fix section literally specified the deferral: "currently: 'Antigravity', 'Claude'; future identities added as harness registry expands". This PR cashes that future-identities marker.

Test Evidence

npm run test-unit -- WakeSubscriptionService.spec.mjs
  33 passed (1.7s)

Spec extension is symmetric:

Existing negative-case test now expects "Must be one of: Antigravity, Claude, Codex" (updated allow-list).
3 positive-case tests (Antigravity / Claude / Codex) replacing the prior single positive-case (Antigravity only). One assertion shape per canonical entry.

Post-Merge Validation

After MCP server restart, WakeSubscriptionService.bootstrap for @neo-gpt AgentIdentity creates a fresh Shape C sub. SQLite SELECT json_extract(data,'$.properties.harnessTargetMetadata.appName') FROM Nodes WHERE id LIKE 'WAKE_SUB:%' AND json_extract(data,'$.properties.agentIdentity') = '@neo-gpt' returns Codex.
bridge-daemon successfully delivers an A2A message addressed to @neo-gpt via osascript to Codex (verified via bridge.log Delivered ... via osascript to Codex line).
If post-merge bootstrap still fails despite the validation fix, the residual cause is the GraphService cache staleness @neo-gpt flagged — separate ticket scope, NOT this PR.

Out of Scope (separately tracked)

bridge-daemon stdio:'ignore' swallows osascript stderr. The 3 failures here were initially undiagnosable until @neo-gpt's manual probe surfaced the underlying TCC denial. Pure observability defense-in-depth, will be filed as a separate ticket.
MCP GraphService cache staleness on AgentIdentity at restart (separate substrate concern).
macOS TCC keystroke permission revocation at process-tree restart — addressed by @tobiu in System Settings; not a code concern.

Parent: #10601 (substrate-stack Epic, lane #5 canonical wake routes)
Direct precursor: #10624 / PR #10628 (introduced the allow-list with the literal "future identities" deferral marker)
Trio canonicalization: PR #10631 (#10625 all-agent-idle detection) — NEO_TRIO_IDENTITIES env default lists @neo-gpt explicitly
Substrate-truth class siblings: #10619 Cycle 1 (AGENT_MEMORY label drift), #10623 Cycle 1 ($.label query drift) — same allow-list-incompleteness failure family

● # PR Review Summary

Status: Approve+Follow-Up

Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve+Follow-Up

Rationale: This PR cleanly fixes the validAppNames validation gap that excluded Codex from Shape C subscription writes, with focused test coverage. The live wake regression still has separate residual surfaces (GraphService cache staleness, osascript/TCC delivery, bridge-daemon stderr observability), but those are correctly scoped out and should not block this narrow substrate-truth fix.

Peer review of #10637. The implementation matches #10636's acceptance criteria and the focused WakeSubscriptionService spec passes locally.

Context & Graph Linking

Target Epic / Issue ID: Resolves #10636

Related Graph Nodes: #10601, #10624 / PR #10628, #10631 / #10625, #10619, #10623, WakeSubscriptionService, validAppNames, Shape C bridge-daemon wake delivery, @neo-gpt, AgentIdentity.subscriptionTemplate

Depth Floor

Challenge / follow-up concern: This PR removes one concrete validation blocker, but it does not by itself prove live Codex wake delivery after restart. The PR body already scopes that correctly: if post-merge bootstrap still fails, the remaining suspects are GraphService cache staleness and/or osascript/TCC delivery. Post-merge validation needs to distinguish those surfaces instead of treating this PR as the entire wake recovery.

Rhetorical-Drift Audit:

PR description: the body accurately frames this as the allow-list validation gap and explicitly scopes out cache staleness / TCC / stderr observability.

Anchor & Echo summaries: the new validAppNames prose matches the mechanical implementation and explains why completeness is load-bearing.

[RETROSPECTIVE] tag: N/A; none present.

Linked anchors: #10624 / PR #10628, #10631, #10619, and #10623 are relevant to the allow-list / substrate-truth framing.

Findings: Pass.

Graph Ingestion Notes

[KB_GAP]: None blocking. The modified property documentation now names the canonical trio and explains why a missing app name strands Shape C wake delivery.

[TOOLING_GAP]: GitHub API calls intermittently returned error connecting to api.github.com while collecting measurement payloads, but required PR state, issue, diff, mergeability, and test checks succeeded on retry or via MCP.

[RETROSPECTIVE]: Static allow-lists around wake substrate routing are small but load-bearing; every canonical harness identity needs symmetric positive and negative validation coverage, otherwise restart-time bootstrap failures can silently degrade a single agent family.

Provenance Audit

N/A for new abstraction. This is an internal substrate bug fix derived from #10636 and the prior #10624 allow-list design, not a new imported architecture.

Close-Target Audit

Close-targets identified: Resolves #10636

#10636 labels verified: bug, ai, regression, architecture; not epic

Syntax is newline-isolated, not prose-embedded or comma-separated.

Findings: Pass.

MCP-Tool-Description Budget Audit

N/A. This PR does not touch ai/mcp/server/*/openapi.yaml.

Wire-Format Compatibility Audit

No JSON-RPC notification schema or payload envelope changes.

Existing harnessTargetMetadata.appName wire shape is preserved.

The changed behavior is validation acceptance for canonical Codex, not a downstream payload change.

Findings: Pass.

Cross-Skill Integration Audit

No skill file, AGENTS.md, or AGENTS_STARTUP.md convention is changed.

The PR updates the service-side validation list backing the existing wake-subscription convention.

Existing identity source verifies @neo-gpt has subscriptionTemplate.harnessTargetMetadata.appName: 'Codex'; the PR makes that canonical template accepted by the service validation gate.

Findings: Pass.

Test-Execution Audit

Branch checked out locally via checkout_pull_request.

git diff --check origin/dev...HEAD passed.

Targeted spec executed: npm run test-unit -- WakeSubscriptionService.spec.mjs

Evaluation Metrics

[ARCH_ALIGNMENT]: 95 - 5 points deducted because the static allow-list is still a manual synchronization point, but it matches the existing #10624 design and keeps the fix narrowly scoped.

[CONTENT_COMPLETENESS]: 95 - 5 points deducted because the Anchor & Echo prose is mechanically accurate and useful, though it keeps the local @member-style field documentation rather than introducing a dedicated @summary tag.

[EXECUTION_QUALITY]: 100 - I actively considered direct subscribe validation, bootstrap delegation, lowercase rejection, diff hygiene, and focused spec coverage; no execution defect was observed.

[PRODUCTIVITY]: 100 - I actively considered each #10636 acceptance criterion and confirmed the code, tests, PR body, and post-merge validation section cover the requested scope.

[IMPACT]: 80 - High impact for a tiny diff: restores the service validation path needed for Codex Shape C subscription writes after restart.

[COMPLEXITY]: 25 - Low: one service allow-list plus symmetric unit coverage; the surrounding wake substrate is complex, but this patch itself is intentionally narrow.

[EFFORT_PROFILE]: Quick Win - High operational ROI with limited touchpoints and clear regression coverage.
