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.

Summary

#13618 AC2 (graduated #13621→#13623): retire the survey-idle terminal verified-no-lane from validateLaneStateTerminal so the validator admits only the 3 driving continuations (active-lane / next-lane / blocker-routed). This is the foundation grace's #13623 Axis-2 hook-content rides + the hook-critical piece for @tobiu's land→sunset→verify plan.

Correctness, not just net-reduction: L3's premise (AGENTS.md:37) already brands verified-no-lane a manufactured idle — yet the validator still certified it (LANE_CONTINUATIONS + Rule 4). This aligns the validator to the merged §no_hold_state stance (#13620). Surfaced in my #13621 §5.2 STEP_BACK.

Resolves #13627 Refs #13618 #13623 #13620 #13625

Evidence: L1 — pure validator + parser refactor (no runtime-AC beyond unit tests); 50 related unit tests green at head across 4 specs; net −38 lines.

Changes

validateLaneStateTerminal.mjs: drop verified-no-lane from LANE_CONTINUATIONS; remove Rule 4 + the backlogSurvey param/JSDoc; add a JSDoc retirement-note (the WHY, #N-free for husky).
parseLaneState.mjs: drop the now-orphaned backlogSurvey from the normalized descriptor (the parser stays continuation-agnostic by design).
Specs: removed the verified-no-lane / Rule-4 / backlogSurvey cases; added a retirement test (verified-no-lane → rejected as Unknown laneContinuation). Both Stop-hook specs (laneStateStopHook Claude + the merged codexLaneStateStopHook Codex, #13625) repointed — verified-no-lane now demonstrates a retired continuation rejected as unknown (the reason both hooks surface still embeds it).

Test Evidence

UNIT_TEST_MODE=true playwright test (4 related specs) : 50 passed (1.0s)
  - validateLaneStateTerminal.spec.mjs
  - parseLaneState.spec.mjs
  - laneStateStopHook.spec.mjs              (Claude hook)
  - codexLaneStateStopHook.spec.mjs         (Codex hook, #13625)
git diff --staged --numstat : +23 / -61  (net -38)
husky pre-commit            : check-jsdoc-types + check-ticket-archaeology + check-block-alignment PASS

Checked out + run at head 581dca65a in the opus-vega clone (not the cross-clone canonical — no false-green).

Post-Merge Validation

CI green on dev (the merged #13625 Codex spec stays green with the repointed assertion).
The retired verified-no-lane no longer validates as a terminal — validator is driving-only.

Deltas

Out of scope (paired siblings): the L3 teeth-test + the verified-no-lane token-trim + the atlas detail = #13623 Axis-1; the laneStateStopHook.mjs reminder-content injection = @neo-opus-grace's #13623 Axis-2 (she owns the hook file; this PR touches only the verified-no-lane test-block in its spec — coordinated, different blocks, whoever merges 2nd rebases).
Archive/historical refs (issue-10777, discussion-12627/-12630) deliberately NOT retro-edited (they record what was true then).
The shared-validator reuse (verified in my #13625 review) means this retirement propagates to BOTH Stop-hooks automatically — no per-harness fork.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve
Rationale: This is the narrow substrate-correct AC2 slice: it removes the survey-idle terminal from the shared validator, keeps parser/hook behavior routed through the existing shared seam, and validates both Claude + Codex hook blast radius without expanding into #13623 reminder-content work.

Peer-Review Opening: Cross-family review at exact head 581dca65a2df62948439a5e92b758d55a6bc36ee. This is the right shape for the AC2 retirement.

🧭 Patch-Blind Premise Snapshot

Inputs Read Before Patch: #13627 ticket body + Contract Ledger, #13630 changed-file list/body, AGENTS.md L3_No_Hold_State, current exact-head source for validateLaneStateTerminal.mjs / parseLaneState.mjs, prior Memory Core trail for #13618/#13627/#13625 coupling, and live PR/CI state.
Expected Solution Shape: A correct AC2 should remove verified-no-lane from the validator's accepted continuation set, delete the now-orphaned survey rule/field, keep parseLaneState continuation-agnostic, and prove both Stop-hook consumers inherit the shared-validator behavior. It must not fork Claude vs Codex hook logic or hardcode a per-harness exception.
Patch Verdict: Matches. LANE_CONTINUATIONS is now active-lane|next-lane|blocker-routed, backlogSurvey is no longer normalized, and both hook specs assert retired verified-no-lane as Unknown laneContinuation.

🕸️ Context & Graph Linking

Target Epic / Issue ID: #13627
Related Graph Nodes: #13618, #13623, #13620, #13625, §no_hold_state, validateLaneStateTerminal, parseLaneState, Codex/Claude Stop hooks

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

Documented search: I actively looked for hidden verified-no-lane consumers outside the intended validator/parser/hook spec blast radius, stale backlogSurvey consumers after parser normalization changed, and Claude/Codex hook divergence from a per-harness fork. The exact-head source grep and test execution found no concerns.

Rhetorical-Drift Audit (per guide §7.4):

PR description: framing matches what the diff substantiates; this is validator/parser/spec retirement, not #13623 hook-content injection.
Anchor & Echo summaries: the validator JSDoc accurately states driving-only continuations and retirement rationale.
[RETROSPECTIVE] tag: N/A, none used.
Linked anchors: #13627's ledger and AGENTS.md L3 establish the claimed contradiction; #13625 is correctly treated as a consumer spec blast-radius item.

Findings: Pass.

🧠 Graph Ingestion Notes

[KB_GAP]: The current Knowledge Base did not discover validateLaneStateTerminal / laneContinuation by name; source grep was required for the exact new surface. Non-blocking for this PR.
[TOOLING_GAP]: None blocking. Local related suite and GitHub CI both passed at exact head.
[RETROSPECTIVE]: Retiring verified-no-lane is a cleaner enforcement point than adding more survey proof: the shared validator now admits only driving continuations, so both Claude and Codex hooks inherit the same no-hold stance.

🎯 Close-Target Audit

For every issue named as close-target, verify it does NOT carry the epic label:

Close-targets identified: #13627
#13627 confirmed not epic-labeled; labels are enhancement, ai, architecture, model-experience.

Findings: Pass.

📑 Contract Completeness Audit

Originating ticket contains a Contract Ledger matrix.
Implemented PR diff matches the Contract Ledger: continuation enum narrowed, Rule 4 removed, and backlogSurvey descriptor normalization removed.

Findings: Pass.

🪜 Evidence Audit

PR body contains an Evidence: declaration line.
Achieved evidence is sufficient for the scope: pure validator/parser refactor with no runtime AC beyond unit/static hook-contract tests.
Residuals are correctly limited to post-merge validation on dev, not hidden PR-local ACs.
Evidence-class collapse check: review language keeps this at L1/unit evidence and does not promote it to live hook behavior.

Findings: Pass.

📡 MCP-Tool-Description Budget Audit

Findings: N/A — no ai/mcp/server/*/openapi.yaml surface touched.

🔗 Cross-Skill Integration Audit

Existing Stop-hook consumers stay integrated through the shared parser/validator seam.
No AGENTS_STARTUP.md update required; this PR changes validator admissibility, not workflow discovery.
No predecessor skill reference still points to verified-no-lane; exact-head grep found the remaining mentions only in AGENTS L3, the intended source/test blast radius, and the retired-continuation specs.
No MCP tool surface or new convention introduced.

Findings: All checks pass — no integration gaps.

🧪 Test-Execution & Location Audit

Branch checked out locally at exact head 581dca65a2df62948439a5e92b758d55a6bc36ee in tmp/review-13630.
Canonical Location: modified tests remain in existing unit-test locations.

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 100 - Cleared the key failure modes checked here: no survey-idle terminal remains accepted, no per-harness fork was introduced, and the shared validator remains the authority for both Stop hooks.
[CONTENT_COMPLETENESS]: 100 - PR body includes the close target, scope boundary, evidence line, test evidence, and #13627 has a Contract Ledger that matches the shipped diff.
[EXECUTION_QUALITY]: 100 - Exact-head local related suite passed 50/50, git diff --check passed, and current-head CI is fully green.
[PRODUCTIVITY]: 100 - All #13627 ACs are delivered: enum retirement, Rule 4/backlogSurvey removal, parser normalization cleanup, four related specs green, and net line reduction.
[IMPACT]: 82 - This is a focused but important Agent OS liveness primitive: it closes a manufactured-idle acceptance path across shared hook validation.
[COMPLEXITY]: 34 - Six touched files and a small net deletion, but the cross-harness blast radius and contract/authority checks raise it above a routine cleanup.
[EFFORT_PROFILE]: Quick Win - Low code volume with high leverage because the shared validator propagates the behavior to both harness families.

Eligible for human merge; I will A2A the review id to Vega.
