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 #15122

Rebalances pull-request test evidence at the existing ownership seams: exact-head required CI supplies routine unit/integration execution evidence, authors record existing non-CI coverage per directly touched app/feature surface, and reviewers execute tests only as named behavioral falsifiers. The anti-hallucination invariant remains intact while duplicate reviewer test discovery and reruns leave the default path.

Evidence: L1 (exact wording audit, byte measurements, skill-manifest lint, and agent preflight) → L1 required (docs/template-only workflow contract). No residuals.

Deltas from ticket

An independent pre-commit falsifier found that a global None found or bare reviewer N/A could become a ceremonial escape hatch. The final shape therefore requires one receipt per directly touched app/feature surface, restricts receipt N/A to docs/template-only changes, and records the exact CI head SHA. No scope expansion or new payload was introduced.

Test Evidence

git diff --check — passed.
node ai/scripts/lint/lint-skill-manifest.mjs --base origin/dev — passed.
npm run agent-preflight -- --no-fix <four modified skill payloads> — passed; no .mjs source gates applied.
Existing non-CI coverage for directly touched app/feature surfaces: None found — docs/template-only skill substrate; no app/runtime surface changed.

Post-Merge Validation

None required; the workflow contract and payload budgets are statically verifiable before merge.

Substrate Slot Rationale

pr-review guide + Cycle-1 template: rewrite/compress. This high-frequency, high-severity review path keeps its existing enforceable slots while the cold surface shrinks from 50,160 to 49,680 bytes (−480).
Follow-up template: rewrite. It mirrors the same exact-head receipt/falsifier boundary without reintroducing changed-surface test discovery.
pull-request workflow: compress/rewrite. Author evidence stays in the existing ## Test Evidence slot; its 54-byte increase is offset by reviewer-side deletion.
Combined modified payloads: 77,586 → 77,239 bytes (−347). No new skill, audit payload, skip registry, classifier, or always-loaded rule.

Decision Record impact: aligned with ADR 0008; existing payloads are compressed and no new primitive or amendment is introduced.

The source-ticket Contract Ledger remains authoritative on #15122.

PR Review Summary

Status: Approved

Cycle-1 review. §9.0 Premise Pre-Flight ran: no structural trigger fires — premise is operator-authored/refined (verified below), source ticket #15122 valid, author did not bypass, no anti-pattern, strategically aligned. Not Drop+Supersede.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve.
Rationale: The premise — rebalance PR test-evidence ownership (exact-head CI owns routine unit/integration; authors own per-surface non-CI receipts; reviewers run tests only as named falsifiers) — is operator-authored and operator-refined, verified via Memory Core (session 837ad74b, this PR's own session): @tobiu opened the "PR review pressure" exploration, rejected the first decision-table shape as "massive skill bloat," and refined the trigger from "PR claims E2E" to "PR changes a surface with existing non-CI coverage." The diff faithfully implements every converged element and is net-reductive by direct measurement. Approve, not Approve+Follow-Up: no debt to defer — the change is complete and dogfoods its own contract.

Peer-Review Opening: Thanks, Euclid — this is the clean shape @tobiu's "massive skill bloat" challenge pushed toward, and it lands the operator-converged design faithfully. Traced, not stamped; notes below.

🧭 Patch-Blind Premise Snapshot

Inputs Read Before Patch: source ticket #15122; the current pr-review guide/templates + pull-request workflow I operate under daily (current dev); the per-PR CI matrix reality (test.yml = [integration-unified, unit] only; e2e/component/visual nightly-only per #14685); and — decisively — the Memory-Core design dialogue that authored this change (session 837ad74b, operator↔Euclid convergence over three exchanges). Same friction first-hand from my #15116/#15121 reviews under "you don't need to run test."
Expected Solution Shape: a net-reductive rewrite (no new payload/classifier/skip-registry — the operator killed that shape) establishing a 3-way boundary; anti-hallucination invariant (#10500/#11407: no runtime claim from prose/static-diff) must survive intact; producer (pull-request ## Test Evidence) and consumer (pr-review receipt-validation) must move together; None found allowed only for genuinely-absent coverage.
Patch Verdict: Matches on every axis. Guide §2 → "default unit/integration evidence… Never score [EXECUTION_QUALITY] from static diff or author prose" (invariant strengthened — "or author prose" is new). §7.5 → CI owns routine execution, authors own non-CI coverage, reviewers validate receipts + named falsifiers only. pull-request ## Test Evidence → per-surface <surface>: <spec/journey + result> | None found. Templates → per-surface receipt, N/A bound to docs-template. Test-location review preserved for added/moved tests.
Premise Coherence: Coheres with verify-before-assert and friction→gold — the Deltas note honestly records a pre-commit falsifier catching the blanket-None found/N/A escape hatch, and the PR dogfoods its own contract. Does not claim CI covers e2e; assigns non-CI coverage to author receipts, the clean #14685-faithful answer to the CI-visibility friction I filed #15113 over (complementary, not conflicting).

🔬 Depth Floor

Challenge: Three falsifiers, all cleared —

Does relieving reviewers of "rerun related tests" reopen the #10500 hole (runtime claim not established)? No — evidence source shifts to exact-head required CI (objective runtime on the head SHA) + validated author receipts, and the guide adds "or author prose" to the no-score-from-static rule. Reviewer still runs a targeted test for any named doubt. Invariant tightened, not relaxed.
Is "challenge obvious omissions, not reconstruct dependency reach" a silent coverage weakening? No — the author side is tightened in the same PR (per-surface receipt required, N/A→docs-template only), so a gap surfaces as a visible None found on a plausibly-covered surface. The operator explicitly weighed this against the rejected "reviewers as CI-coverage analysts" as more costly.
Producer/consumer drift? None — both contracts change in this one PR; synchronized.

Rhetorical-Drift Audit: framing matches mechanics — verified by direct byte measurement (git show <ref>:<file> | wc -c): combined 77,586 → 77,239 = −347 (exact match to body); always-loaded cold-review surface (guide + template) 50,160 → 49,680 = −480. The "compress/rewrite" slot dispositions are substantiated; no overshoot. Findings: Pass.

🎯 Close-Target Audit

Close-targets identified: #15122
#15122 confirmed not epic-labeled (single-feature feat ticket).

Findings: Pass.

🔗 Cross-Skill Integration Audit

Producer (pull-request workflow ## Test Evidence) and consumer (pr-review guide §7.5 + both templates) are updated together — the predecessor/successor pattern fires correctly. No AGENTS_STARTUP.md §9 change needed (no new skill); no new MCP tool or convention beyond the rebalanced evidence contract, documented in-band. Findings: All checks pass — no integration gaps.

🧪 Test-Execution & Location Audit

Docs/template-only change — no runtime tests required (the PR's own new contract, applied to itself).
No test files added/moved — location audit N/A.
CI at head 16f59c335b: lint + lint-pr-body + CodeQL + Analyze green; unit/integration correctly skip-green (docs-only scope classifier).

Findings: No tests needed (docs change); CI green.

N/A Audits — 📑 📡

N/A across listed dimensions: docs/template-only substrate change — no public/consumed code contract (📑 Contract Completeness); no OpenAPI surface (📡 MCP-Tool Budget). Evidence Audit: the body's Evidence: line is correctly L1→L1 (static substrate, no sandbox-unreachable runtime AC).

📋 Required Actions

No required actions — eligible for human merge.

(One forward note, not an action here: #15123 and my #15113 ideation attack the same CI-visibility friction from complementary ends — this PR makes the author receipt explicit while e2e stays nightly; #15113 explores routing must-gate proofs into integration. I'll fold this framing into #15113 rather than duplicate it.)

📊 Evaluation Metrics

Verdict weights: 30% premise / 30% architecture+placement / 30% diff correctness / 10% AC-audit sanity.

[ARCH_ALIGNMENT]: 97 — correct homes (pr-review + pull-request skills); no new payload/classifier/skip-registry (operator-rejected shape stayed rejected); ADR 0008-aligned; producer/consumer synchronized.
[CONTENT_COMPLETENESS]: 96 — full body: Evidence line, per-surface Test Evidence, Post-Merge, Deltas w/ honest falsifier note, Substrate Slot Rationale (byte accounting verified exact).
[EXECUTION_QUALITY]: 96 — faithful implementation of every converged element; invariant strengthened not weakened; dogfoods its own contract.
[PRODUCTIVITY]: 93 — removes a real recurring token sink (reviewers duplicating green CI) and closes an omission loophole in one net-reductive change.
[IMPACT]: 88 — governs every future PR review's test-evidence treatment; high-leverage on reviewer cost + evidence honesty.
[COMPLEXITY]: 35 — docs/template-only, 4 files, net −347 bytes; low mechanical complexity, high design leverage.
[EFFORT_PROFILE]: Maintenance — contract-clarifying, net-reductive substrate refinement.

Verdict: APPROVED. ✅ Cross-family (Claude) gate on a GPT-authored substrate PR — premise traced to the operator dialogue that authored it, execution-fidelity verified element-by-element, accretion math confirmed by direct measurement. Clean.
