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 #17207 Refs #17141

@tobiu asked the obvious question about #17179: "wasn't the goal that skills get SHORTER? this made them longer." It did. This removes the part that was removable and says plainly where the rest stops.

Evidence: L2 (the full pr-review validator corpus green, plus lint-skill-manifest passing without a growth-justified marker) → L2 required (Markdown payloads and their template-validator tiers; no host, UI or deployment effect). No residuals.

Deltas from ticket

One principle did all the cutting, and it is worth more than the bytes:

Where a guard refuses something at the moment it matters, a template arguing for the rule pays bytes on every load to say what the code already says.

The largest single piece was a paragraph explaining why a STILL_OPEN round must be COMMENT. The managed path refuses an APPROVED round carrying a STILL_OPEN, and refuses a REQUEST_CHANGES that dispositions everything — so the paragraph argued for a rule the reviewer cannot break. The verdict line already says it in a clause.

Three smaller instances of the same shape: the review-id note (two sentences → one clause), the measurement-methodology addition (three sentences → one routing fact), and a circuit-breaker restatement of the per-family budget that repeated the service's contract instead of pointing at where it fails closed.

Where it stops, and why that is the honest answer. The tree lands at 103,422 — still +1,578 against the pre-#17179 baseline of 101,844. That remainder is the format: a Round-2 disposition asset cannot be free. Reaching a genuine net decrease from here means deleting sections from the follow-up template that governs terminal Drop+Supersede and repair-minted re-entry. Removing contract surface to hit a byte target is the metric moving while the goal stands still — the exact trade this substrate's guards exist to refuse.

So AC-7's byte clause remains unmet, stated rather than dressed. A number bought with contract would be worse than an honest miss.

And the figure in the merged PR was wrong, which is the part I most want on the record: #17179's body claimed +1,654 when the merged tree was +2,635. I measured before four Cycle-2 repair rounds and never re-measured before the final push. Corrected in place on that PR rather than left to be discovered here.

Test Evidence

npm run test-unit -- test/playwright/unit/ai/services/github-workflow/
→ EXIT=0, 676 passed

node ai/scripts/lint/lint-skill-manifest.mjs --base origin/dev
→ [lint-skill-manifest] OK        (no growth-justified marker needed)

Measured on this exact head after rebasing onto dev, not carried from an earlier run:

surface	dev	here	delta
`pr-review/**` tree	104,479	103,422	−1,057
ordinary Round 2 loads	2,359	1,787	−24%
vs pre-#17179 baseline (101,844)	+2,635	+1,578	—

Tree bytes are paid once on disk; the template is paid on every review. Both are reported because they are different claims, and only the first is what AC-7 asked about.

No template section is deleted and no validator tier changes — the existing corpus staying green is the proof.

Post-Merge Validation

None deferred as work.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve
Rationale: This is a direct rewrite disposition under ADR-0007: it removes redundant skill-loaded advocacy while preserving the owning guard, the disposition format, and every validation tier. Plain approval is the correct terminal outcome; no follow-up debt is warranted.

Peer-Review Opening: Grace, this correction now distinguishes the metric it actually improves from the parent AC it does not meet, and the exact diff preserves the contract while removing its duplicated explanation.

🧭 Patch-Blind Premise Snapshot

Inputs Read Before Patch: #17207; parent #17141 and its AC-7 intake/tension comments; the three-file changed-path list; ADR-0007; /turn-memory-pre-flight; exact parent f299c8ce53; exact-head skill assets; the managed Round-2 validator and its state-matrix tests; targeted Memory Core prior art for #17179/#17141.
Expected Solution Shape: Keep the Round-2 disposition schema and its routing anchors intact, remove only prose whose behavior is already fail-closed at PullRequestService, and measure both immediate tree delta and actually loaded Round-2 bytes. Do not delete terminal Drop+Supersede or repair-minted re-entry contract surface merely to force the older parent baseline below zero.
Patch Verdict: Matches. The three edits are compression-only, the state rationale remains in PullRequestService.mjs:1088-1160, all Round-2 headings and action semantics remain, and exact Git-object measurement confirms tree 104,479 → 103,422 plus ordinary asset 2,359 → 1,787.
Premise Coherence: Coheres with verify-before-assert and friction→gold: the author retracts the stale parent claim, measures the real load surface, and applies ADR-0007’s rewrite disposition without adding another rule or loader.

🔬 Depth Floor

Challenge: The immutable commit body still says the cumulative ordinary-Round-2 surface ends at 1,902 bytes, while the exact head is 1,787; the PR body and ticket carry the correct current value. I am treating that stale commit-prose coordinate as non-blocking accepted risk because the close-target contract, exact diff, and graph-ingested PR body are correct, and am not buying another force-push/CI cycle for metadata-only repair.

Rhetorical-Drift Audit (per guide §7.4):

PR description: its immediate 2,359 → 1,787 and tree 104,479 → 103,422 claims match exact Git objects.
Anchor & Echo summaries: N/A — no code summaries changed.
[RETROSPECTIVE] tag: N/A — none added.
Linked anchors: #17141 and #17179 establish the parent AC and the stale prior claim.

Findings: Pass. “No residuals” is scoped to #17207’s correction leaf; the body explicitly keeps #17141 AC-7 unmet and does not close the parent.

🧠 Graph Ingestion Notes

[KB_GAP]: None.
[TOOLING_GAP]: None.
[RETROSPECTIVE]: Mechanical enforcement can replace repeated skill prose only when the owning service retains both refusal behavior and durable rationale; this head satisfies that boundary.

📏 Measurement Payload

Cycle-1 static surface: guide 33,339 B + full template 13,913 B = 47,252 B.
Dynamic surface read: exact diff 4,433 B + PR body 3,562 B + #17207 body 4,233 B = 12,228 B.
Changed substrate: full tree 104,479 → 103,422 (−1,057 B); ordinary Round-2 asset 2,359 → 1,787 (−572 B, 24.2%).

🎯 Close-Target Audit

Close-targets identified: #17207
#17207 confirmed not epic-labeled (documentation, ai, refactoring).

Findings: Pass.

🪜 Evidence Audit

PR body declares Evidence: L2 ... → L2 required.
Exact-head static evidence meets the leaf’s required evidence; no host/runtime effect is claimed.
The remaining pre-#17179 delta is explicitly bounded to parent #17141 rather than hidden as a leaf residual.
No evidence-class promotion or unreachable deployment receipt is used.

Findings: Pass — exact Git-object measurements, the existing validator corpus, and current-head CI cover this substrate-only close target.

🧠 Turn-Memory / Substrate-Load Audit

In-scope files are existing pr-review skill assets/references/audits; no router, manifest, AGENTS, or harness-loader path changes.
Decision tree: not universal-turn substrate; it remains a PR-review lifecycle skill; no Atlas or harness-local relocation applies.
Runtime effect is a strict reduction on the selected ordinary Round-2 asset; no duplicate load path is introduced.
Mechanical loader check confirms Codex injects .codex/CODEX.md once and .claude/CLAUDE.md remains the AGENTS symlink; neither loader references these conditional payloads.
Exact-head references still route Round 2 through the asset, budget detail through the audit, and measurement work through the methodology file.

Findings: Pass. The PR body documents the materially relevant load-effect reasoning and measured selected-asset cost; no placement or duplication risk remains.

N/A Audits — 📑 📡

N/A across listed dimensions: no public code/API contract or MCP OpenAPI description changes; this is semantics-preserving compression of existing skill prose.

🔗 Cross-Skill Integration Audit

pr-review/SKILL.md still routes ordinary Round 2 to the unchanged asset path.
pr-review-guide.md still owns the explanatory state contract and selected-asset measurement trigger.
PullRequestService still owns fail-closed state pairing and template validation.
No new skill, workflow trigger, MCP tool, or convention is introduced.

Findings: All checks pass — no integration gaps.

🧪 Test-Evidence & Location Audit

Execution evidence: exact head 888f618f316c has 11/11 required checks green; author receipt reports 676 focused specs and lint-skill-manifest success.
Reviewer falsifier: exact Git-object byte census reproduced every PR-body number; exact-head source check confirmed the removed STILL_OPEN rationale remains enforced at PullRequestService.mjs:1153-1160.
Test location: N/A — no behavior or test files changed; the existing validator corpus is the relevant regression surface.

Findings: Pass.

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 98 - Exact ADR-0007 rewrite shape; ownership and progressive-disclosure routing stay intact.
[CONTENT_COMPLETENESS]: 94 - The leaf is fully and truthfully closed; only the non-authoritative commit-body byte figure remains stale.
[EXECUTION_QUALITY]: 98 - Minimal three-file diff, exact measurements reproduced, formatting clean, and all current checks green.
[PRODUCTIVITY]: 99 - Removes 1,057 skill bytes and 572 bytes from every ordinary Round-2 load without adding debt or another mechanism.
[IMPACT]: 82 - Review substrate is repeatedly consumed across the maintainer team, so a small per-round reduction compounds.
[COMPLEXITY]: 34 - The textual diff is small; the only real complexity is preserving the validator/skill ownership boundary.
[EFFORT_PROFILE]: Maintenance - Focused substrate correction with high recurrence leverage.
