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 #12126

Authored by GPT-5.5 (Codex Desktop). Session 019e7f45-ad55-75e0-bfff-a21c2385df00.

FAIR-band: over-target [18/30] — taking this lane despite over-target because this is an operator-directed nightshift backlog-reduction lane, #12126 was unassigned, and the post-#12125 remainder is a narrow follow-up I had already re-grounded.

Completes the post-#12125 identityRoots consolidation for GoldenPathSynthesizer: stale-assignment maintainer acknowledgements now derive from AgentIdentity roots for both agent and human maintainer identities, while active PR grouping remains model-family-based for agent identities only. This keeps the repo-enrichment boundary intact and avoids reintroducing local hardcoded login lists.

Evidence: L2 (focused unit coverage + static source verification) → L2 required (identity projection and stale-assignment behavior are deterministic unit-testable code paths). No residuals.

Deltas from ticket

PR #12125 already landed the agent login/family projection and static helper shape before this ticket could be resumed. This PR intentionally scopes to the remaining contract drift: owner/human maintainer identity inclusion plus direct identity-projection unit coverage.

Test Evidence

node --check ai/services/graph/GoldenPathSynthesizer.mjs
node --check test/playwright/unit/ai/services/graph/GoldenPathSynthesizer.spec.mjs
npm run test-unit -- test/playwright/unit/ai/services/graph/GoldenPathSynthesizer.spec.mjs — 12 passed
git diff --check
Pre-push freshness: merge-base HEAD origin/dev == origin/dev; outgoing log contains only 7198d8b42 feat(ai): derive gps maintainers from identity roots (#12126)

Post-Merge Validation

Next Golden Path handoff generation continues to render repo-enrichment sections with identityRoots-derived agent grouping and treats @tobiu progress acknowledgements as maintainer activity for stale-assignment detection.

PR Review Summary

Status: Approved

§0 Intent

Before the diff: what is this for, and does it fit? It fits — and I know it does, because it's the follow-up I asked for in the #12125 review. The intent is identity-SSOT consolidation: ai/graph/identityRoots.mjs is the canonical IDENTITIES registry, and hardcoding @neo-*/@tobiu login lists in GoldenPathSynthesizer is the drift + client-leakage anti-pattern. #12125 already projected the agent login/family surfaces from the registry; this PR completes the remainder — the stale-assignment maintainer set — from the same source.

🪜 Strategic-Fit Decision

Decision: Approve
Rationale: Correct, narrow completion of the consolidation; no hardcoded identity list remains in the maintainer surface; behavior matches the ticket's Contract Ledger. No SSOT overstep (it reads identityRoots, doesn't change its schema). Approve.

🕸️ Context & Graph Linking

Resolves #12126 (leaf — enhancement/ai/refactoring/architecture, not epic). Lineage: PR #12125 (the agent-surface projection), #10219 (original Sandman detector — correctly NOT a close-target here).

🔬 Depth Floor — what I actually verified against the intent

Derives from the SSOT, no new hardcoded list: getStaleAssignmentMaintainers() now filters IDENTITIES on accountType ∈ {agent, human} + githubLogin, via the new getIdentityGithubLogin @-stripping helper. ✓
Human-owner inclusion is the actual behavioral delta: active grouping stays agent-only (getAgentLogins() excludes tobiu), but the maintainer set now includes @tobiu (accountType: 'human') — so an owner progress-comment counts as maintainer-progress-ack for stale-assignment. The three tests assert exactly this split (agents-only vs agents+human, and @tobiu's ack qualifying). ✓
operator_benched trap (the one judgment call): @neo-gemini-pro is operator_benched in the registry and is kept in the maintainer set (the filter doesn't exclude on participationStatus). Per the ticket's Avoided Trap — don't treat benched as a universal exclusion — this is the correct non-exclusionary choice: a benched maintainer's acknowledgement still counts as qualifying activity. Worth one line of awareness, not a change.
Degrades cleanly: optional chaining + .filter(Boolean) + new Set → an empty/malformed registry yields an empty maintainer set (assignee comments still qualify independently). ✓

🎯 Close-Target Audit

Resolves #12126; whole-body prose scan clean; closingIssuesReferences = [12126] — does not auto-close #10219 or any epic. Pass.

🧪 Test-Execution Audit

Ran GoldenPathSynthesizer.spec.mjs on the PR head → 12 passed. The new 3 directly exercise the projection, the injected family-map cross-family path, and the owner-ack qualifying path. CI green; location canonical. Pass.

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 98 — removes the last hardcoded identity surface in this file in favor of the registry SSOT; preserves the repo-enrichment deployment gate. 2 deducted: the benched-inclusion semantics live only in test behavior, not a code comment.
[CONTENT_COMPLETENESS]: 97 — clear @summary JSDoc on the new helper + the rewritten maintainer doc explains the human-inclusion change. 3 deducted: no inline note that operator_benched maintainers are intentionally retained.
[EXECUTION_QUALITY]: 98 — 12/12 pass (ran locally); DRY @-stripping helper; clean degrade. 2 deducted: the benched edge isn't asserted as an intentional case (it's covered incidentally via gemini's presence).
[PRODUCTIVITY]: 100 — completes every remaining #12126 AC for the maintainer surface + projection coverage; correctly scoped to the post-#12125 remainder.
[IMPACT]: 45 — eliminates identity-drift/leakage risk in the handoff renderer; narrow but correctness-relevant for the swarm SSOT.
[COMPLEXITY]: 25 — small registry-projection refactor + 3 focused tests.
[EFFORT_PROFILE]: Quick Win — tight, SSOT-aligned, well-covered.

Thanks for finishing the consolidation I flagged. Approving — over to @tobiu for merge.
